Answer:

4 hours = 3

t hours = 11-2t

Step-by-step explanation:

11 gallons = total

2 gallons are used up per hour

So:

11 - 2 * ( number of hours) = number of gallons

11 - (2 * 4) = 11 - 8 = 3

Let's solve the problem,

\( \sf \rightarrow \: 15 \times \frac{5}{12} \)

\( \sf \rightarrow \: \frac{(15 \times 5)}{12} \)

\( \sf \rightarrow \: \frac{75}{12} = 6.25\)

Hence, the product is 6.25.

Step-by-step explanation:

1. 135, 205, 330, 275, and 365 are divisible by 5.

2.  1, 4, and 7 can be filled in the blank space to make it divisible by 3.

3. 1, 2, 3, 5, 6, 10, 15, and 30 are the factors.

4. 81 is the only composite number all the other nos. are prime.

Divisibility rules are methods for determining whether a number is divisible by a certain number or not without actually dividing.

We know numbers that are divisible by 5 are those numbers

having 5 or 0 in their unit place.

∴ 135, 205, 330, 275, and 365 are divisible by 5.

A number is divisible by 3 if the sum of all the digits is divisible by 3.

∴ 3,71_ has a digit sum of 11, so 1, 4, 7 can be filled in the blank space to make it divisible by 3.

A list of all the factors of 30 is those numbers that divide 30 completely.

∴ 1, 2, 3, 5, 6, 10, 15, and 30 are the factors.

We know composite numbers are those numbers that are not prime.

∴ 81 is the only composite number all the other nos. are prime and they have only two factors 1 and the number itself.

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:

a² = b²+c²

As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:

b = √(a²-c²) b = √(10²-4²) b = 9.16

With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10

Answer:  288q - 185 = 236q - 245

Explanation:

A product is the result of multiplying. So "product of 288 and q" means "288 times q" or "288*q" or simply "288q".

Clades that reflect true evolutionary history can be determined by using synapomorphies, which are shared derived characteristics that are unique to particular groups of organisms.

These synapomorphies indicate common ancestry and help in identifying and defining clades accurately. Overall similarities between organisms can also provide evidence for evolutionary relationships, but it is the presence of shared derived characteristics (synapomorphies) that specifically indicate clades. Ancestral traits and homoplasies (analogous characteristics that arise independently) may not accurately represent evolutionary history and can potentially lead to incorrect clade assignments. Carbon isotopes, on the other hand, are primarily used in studies of paleontology and paleoecology to understand ancient environments and diets, but they are not typically used as a direct method for determining clades or evolutionary relationships.

Answer:

Step-by-step explanation:

Therefore, the image is formed at a distance of approximately 46.03 cm behind the mirror, and its height is approximately 2.98 cm.

We'll use the mirror formula and magnification to find the height of the image produced by the convex mirror.
1/f = 1/do + 1/di
do = object distance = 17 cm
f = focal length = -59 cm
Now, let's solve for the image distance (di):
1/-59 = 1/17 + 1/di
1/di = 1/-59 - 1/17
1/di ≈ -0.0217
di ≈ -46.03 cm
The magnification (M) is given by:
M = -di/do
M ≈ 46.03/17
M ≈ 2.71
Now, let's find the height of the image (hi):
hi = M * object height
hi = 2.71 * 1.1
hi ≈ 2.98 cm

Therefore, the image is formed at a distance of approximately 46.03 cm behind the mirror, and its height is approximately 2.98 cm.

The simplified expression is: \(-75x^{13}y^{10\)

Given is an expression \((-3x^3y^2)(5x^5y^4)^2\), we need to find the simplified expression,

To find the expression that is equivalent to  \((-3x^3y^2)(5x^5y^4)^2\), we can simplify the given expression using the properties of exponents.

Let's break down the expression step by step:

\((-3x^3y^2)(5x^5y^4)^2\)

First, we can square the second term \((5x^5y^4)^2\):

\((-3x^3y^2)(25x^{10}y^8)\)

Next, we can simplify the expression by multiplying the coefficients and combining the variables:

-3 × 25 = -75

\(x^3 \times x^{10} = x^{(3+10)} = x^{13\)

\(y^2 \times y^8 = y^{(2+8)} = y^{10\)

Therefore, the simplified expression is:  \(-75x^{13}y^{10\)

\(H_0:p=0.12\\\\H_a:p<0.12\)

Step-by-step explanation:

Null hypothesis\((H_0)\) : A statement describing population parameters as per the objective of the study. It usually takes "≤,≥,=" signs.  

Alternative hypothesis \((H_a)\): A statement describing population parameters as per the objective of the study. It usually takes ">, <, ≠" signs.

Let p be the proportion of screens that will be rejected.

12 percent of the screens manufactured using a previous process were rejected at the final inspection.

(i.e. p= 0.12)

Objective of the study = whether the new process reduces the population proportion of screens that will be rejected

i.e. p< 0.12

So, the appropriate hypotheses to investigate whether the new process reduces the population proportion of screens that will be rejected:

\(H_0:p=0.12\\\\H_a:p<0.12\)

Using translation concepts, the graph of g(x) is given as follows:

It goes through (2, 10), has a vertex at (5, 1), and goes through (8, 10).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent and translated functions are given, respectively, by:

The transformations are as follows:

f(x) has vertex at (0,0), hence g(x) will have the vertex at (5,1). When x = 2, g(x) = (2-5)^2 + 1 = 10, hence the correct statement is:

Three types of rigid transformations are Reflection, Rotation, and Translation. Rigid transformation, also called isometry.

A rigid transformation, also called isometry,  is a transformation that doesn't change the size or shape of a geometric figure. The following are 3 types of rigid transformation:

1. Reflection

→  is the act of shifting an object's coordinates that flip it across a line without changing its shape or size. Horizontal (draw a figure to the left or right) or vertical (draw a figure to the up or down) reflections are possible. The result of reflection is a mirror image of the figure itself.  

The figure is reflected across \(x-\) or \(y-\) axis, and then change \(x-\) or \(y-\) coordinate.

2. Rotation

→ is the non-modification of an object's size or shape by rotating it around an fixed point. A center of rotation is required to rotate an object. And the rotation did by using a degree.

The figure is rotated by a degree (ex: 90°), and then change \(x-\) or \(y-\) coordinate. Meanwhile, a point's center rotation stays at the same.

3. Translation

→ is sliding a figure in any direction without changing its size, shape, or orientation. Translation could be horizontal (make a figure left or right),  or vertical reflections (make a figure up or down).

Vertical translation is shifting the graph along  \(y-\) axis

Horizontal translation is shifting the graph along  \(x-\) axis.

The Multi-Step Campers can cut approximately 15 kite lines from the roll of string.

To determine the number of kite lines that can be cut from the roll of string, we need to convert the measurements to a consistent unit. Let's convert the length of the string roll and the kite line to yards.

Since 1 yard is equal to 3 feet, we have:

50 feet = 50/3 yards ≈ 16.67 yards (rounded to two decimal places)

Now, we can calculate the number of kite lines that can be cut from the string roll:

Number of kite lines = Total length of string roll / Length of each kite line

Number of kite lines = 250 yards / 16.67 yards ≈ 15

Therefore, the Multi-Step Campers can cut approximately 15 kite lines from the roll of string.
