Answer:

she has 3 quarters

Step-by-step explanation:

let's call the amount of dimes D

let's call the amount of quarters Q

you know that she has 11 coins in total,

so D + Q = 11.

you also know that each dime is worth 10 cents.

and each quarter is worth 25 cents.

so 10d + 25q = 155

this is a system of equations. solve by substitution:

d = 11 - q

10d + 25q = 155

10(11 - q) + 25q = 155

110 - 10q + 25q = 155

15q + 110 = 155

15q = 45

q = 45/15

q = 3

Answer:

all 3 options are true : A, B, C

Step-by-step explanation:

warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.

they say that A and C are correct.

but I am going to show you that if A and C are correct, then also B must be correct.

therefore, my given answer above is the actual correct answer (no matter what the test systems say).

originally the information about the alignment of the point F in relation to point E was missing.

therefore, I considered both options :

1. F is on the same vertical line as E.

2. F is not on the same vertical line as E.

because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :

the vertical line of EF is like a mirror between the left and the right half of the picture.

A is mirrored across the vertical line resulting in B. and vice versa.

the same for C and D.

this leads to the effect that all 3 given congruence relationships are true.

if we consider assumption 2, none of the 3 answer options could be true.

but if the assumptions are true, then all 3 options have to be true.

now, for the "why" :

remember what congruence means :

both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.

for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.

so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.

therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.

but do you notice something ?

both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.

now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.

therefore, AC must be equal to BD.

and that means that AC is congruent to BD.

because lines have no other congruent criteria - only the lengths must be identical.

Answer: I think it's 6

Step-by-step explanation:

The simplified expression is given by (x² - 3x - 3) / ((x + 3)(x - 2)(x - 4)).

To simplify this expression, we need to find a common denominator for the two fractions and then combine them. To do this, we need to factor the denominators of both fractions.

Let's start with the first fraction's denominator:

x² + x - 6

We need to find two numbers that multiply to -6 and add to +1. These numbers are +3 and -2. Therefore, we can write:

x² + x - 6 = (x + 3)(x - 2)

Now let's factor the second fraction's denominator:

x² - 6x + 8

We need to find two numbers that multiply to 8 and add to -6. These numbers are -2 and -4. Therefore, we can write:

x² - 6x + 8 = (x - 2)(x - 4)

Now we can rewrite the original expression with a common denominator:

(x(x - 2) - (1)(x + 3)) / ((x + 3)(x - 2)(x - 4))

Next, we can simplify the numerator:

(x² - 2x - x - 3) / ((x + 3)(x - 2)(x - 4))

(x² - 3x - 3) / ((x + 3)(x - 2)(x - 4))

Finally, we can't simplify this expression any further. Therefore, the simplified expression is:

(x² - 3x - 3) / ((x + 3)(x - 2)(x - 4))

Unfortunately, I am unable to directly interpret or visualize figures or images. However, I can provide you with a general explanation. In a discretized reservoir using block-centered grids, the standard ordering refers to the arrangement of grid cells or blocks in a particular pattern.

This pattern is often used to establish the connectivity and adjacency relationships between the cells in the reservoir model. Typically, the standard ordering arranges the grid cells in a sequential manner, starting from the top-left corner and moving row by row. Each grid cell represents a discrete volume or unit in the reservoir. The non-zero elements, indicated by the "x" positions in the coefficient matrix, would correspond to the active or connected cells within the reservoir model. These active cells are the ones that contribute to fluid flow and other reservoir properties. To visualize the discretized reservoir using the standard ordering, you would need to refer to the coefficient matrix and determine the dimensions of the reservoir model, such as the number of rows and columns. Then, starting from the top-left corner, you can represent each active cell or block using a graphical representation, such as a square or rectangle, in a sequential manner based on the standard ordering. This way, you can construct a visual representation of the discretized reservoir model.

Thus, we will need 4 hexadecimal numbers to achieve the same values as a 16-bit number.

For the base-5 number we can do a similar procedure:

Therefore, we would need at least 7 numbers base-5 to achieve something similar to 16-Bit number

By solving equations we can conclude that the age of Devaughn and Sydney is 27.5 years and 40.5 years respectively.

In mathematical formulas, the equals sign is used to indicate that two expressions are equal.

A mathematical statement that uses the word "equal to" between two expressions with the same value is called an equation.

like 3x + 5 = 15, for instance.

Equations come in a wide variety of forms, including linear, quadratic, cubic, and others.

So, form the equations as:

Let Devaughn be x and Sydney be s.

Now,

x + 13 = s ...(1)  

x + 13 + s = 21 ...(2)

Now, insert s = x + 13 in equation (2):

x + 13 + s = 81

x + 13 + x + 13 = 81

2x + 26 = 81

2x = 81 - 26

2x = 55

x = 27.5

Now, insert x = 27.5 in equation (1):

x + 13 = s

27.5 + 13 = s

40.5 = s

Therefore, by solving equations we can conclude that the age of Devaughn and Sydney is 27.5 years and 40.5 years respectively.

The original price of the laptop was $862.00

How to calculate the original price

The original price of the laptop, denoted by x, can be found by setting up an equation that relates it to the final price after markup.

We know that the final price of the laptop is $1,137.84, and that this price is 32% higher than the original price.

So, one way to set up an equation to solve for x is to use the formula:

final price = original price + markup

where the markup is defined as a percentage of the original price.

In this case, we can write:

$1,137.84 = x + 0.32x

Simplifying this equation, we get:

$1,137.84 = 1.32x

To solve for x, we can divide both sides by 1.32:

x = $1,137.84 ÷ 1.32

x = $862.00

So the original price of the laptop was $862.00.

Using this approach, we can see that option C (1.32p = 1,137.84) is the correct equation for finding the original price of the laptop.

Option A (p(1 − 0.32) = 1,137.84) is incorrect because it represents the final price, not the original price.

Option B (p + 0.32p = 1,137.84) is also incorrect because it represents the sum of the original price and the markup, which is not what we need to find.

Option D (0.68p = 1,137.84) is incorrect because it represents a calculation that is not relevant to finding the original price.

Option E (p(1 + 0.32) = 1,137.84) is incorrect because it represents a calculation that adds the markup to the original price, which is not what we need to find.

Option F (p − 0.32p = 1,137.84) is also incorrect because it represents the difference between the original price and the markup, which is not what we need to find.

For a uniform distribution random variable X, the probability that the random variable has a value between 0.6 and 2.1 is equals to 0.1875. So, option(a) is right one.

The uniform distribution is defined as a continuous probability distribution and the events are equally likely to occur. In other words in this distribution every possible outcome has an equal probability. There is a uniform distribution of variable. Let the random variable be denoted by X be uniformly distributed. The above figure shows uniform density curve for X. That is \( X \: \tilde \: \: U( 0, 8) \).

Probability density function is f(x) = \(\frac{ 1}{8} = 0.125\)

We have to determine probability that the random variable has a value between 0.6 and 2.1, P(0.6 ≤ X ≤ 2.1). So, required probability is P(0.6 ≤ X ≤ 2.1) = \(\int_{0.6}^{2.1} f(x) dx \).

\(= [ 0.125x ]_{0.6}^{2.1}\)

= 0.125 ( 2.1 - 0.6)

= 0.125 ( 1.5)

= 0.1875

Hence, required value is 0.1875.

3. To get from the base of the cone to the top of the hill, an ant has to crawl 29 mm.

In Mathematics and Geometry, the volume of a cone can be calculated by using this formula:

Volume of cone, V = 1/3 × πr²h

Where:

By substituting the given parameters into the formula for the volume of a cone, we have the following;

8792 =  1/3 × 3.14 × 20² × h

26,376 =  3.14 × 400 × h

Height, h = 26,376/1,256

Height, h = 21 mm.

Question 2.

In order to solve for the slant height, s, we would have to apply Pythagorean's theorem since the height of the cone has been calculated above.

Answer:

Step-by-step explanation:

Answer:

V = 3534 cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

the radius is 7.5 and the height is 20

V = pi ( 7.5)^2 * 20

V =1125 pi cm^3

Using the pi button for pi

V =3534.291735 cm^3

Rounding to the nearest whole number

V = 3534 cm^3

Answer:

b)3534 cm^3

Step-by-step explanation:

To find the area of a cylinder, you first have to find the area of the base which is in the shape of a circle. The area of a circle is given by the equation πr^2. In this case r, the radius, is 7.5 cm. So plugging in 7.5 for r you get 7.5^2 × π. Plugging in 3.1415 for π you get ~176.671. Now all you do is multiply this by the height, 20cm, and get the answer of ~3534 cm^3.

The measure of the angle at the library is 90 degrees.

Since the library is the same distance from both Toru's house and the park, this means that the triangle formed by the three points is an isosceles triangle, with two sides of equal length and two congruent angles.

In an isosceles triangle, the two equal angles are always congruent and add up to 180 degrees. So, the measure of each angle at the library would be:

180 degrees / 2 = 90 degrees

So, the measure of the angle at the library is 90 degrees.

An isosceles triangle is a type of triangle where two sides are of equal length and two angles are congruent. The two equal sides are called the legs and the third side is called the base.
