Answer:

80 degrees

Step-by-step explanation:

The sum of the interior angles of any quadrilateral is 360 degrees. Adding up the known measures gives you 95 + 123 + 62 = 280. Then you can subtract that from 360. 360 - 280 = 80. So x has to be 80 degrees.

What number must be divided by 15 3/4 so that the quotient is 60?

Answers

The type directions that lie in the (110) plane are Crystal planes are equivalent planes that represent a group of crystal planes with a common set of atomic indexes.

Crystallographers use Miller indices to identify crystallographic planes. A crystal is a three-dimensional structure with a repeating pattern of atoms or ions.In a crystal, planes of atoms, ions, or molecules are stacked in a consistent, repeating pattern. Miller indices are a mathematical way of representing these crystal planes.

Miller indices are the inverses of the fractional intercepts of a crystal plane on the three axes of a Cartesian coordinate system.Let us now determine which of the type directions lie in the (110) plane.[101] is not in the (110) plane because it has an x-intercept of 1, a y-intercept of 0, and a z-intercept of 1. So, this direction does not lie in the (110) plane.[110] is in the (110) plane since it has an x-intercept of 1, a y-intercept of 1, and a z-intercept of 0.

Answers

An estimate for the number of blue marbles in the bag is 60.

We have,

To estimate the number of blue marbles in the bag, we can use an expression.

Let x be the estimated number of blue marbles in the bag.

Then, we can set up the expression:

blue marbles in the bag / total marbles in the bag = blue marbles picked / marbles picked.

x / 200 = 3 / 10

Cross-multiplying.

10x = 3 * 200

Simplifying.

x = 60

Taner wants to run a total of 6 kilometers between last week and this week. How far does Taner need to run this week to reach his goal?

Answers

Taner will only need to run 3 km this week to complete his 6 km running goal.

Describe the fractional number in detail:

If we require a definition, we may start by saying that fractional numbers are numbers that symbolize one or possibly more portions of a unit that has been subdivided into equal parts.

To determine the fractional numbers, two whole numbers (including fraction terms) are separated by a horizontal line (the fraction line). The denominator just below line must be different from zero, whereas the numerator well above line may be any whole number.

Given that, Taner's overall running goal is 6 km (including last week and this week)

So,

Taner's 2-week goal is 6 kilometres.

Now,

Taner's goal for the week is 3 kilometres = (6/2).

As the Taner completed 3 km of running last week. Taner can achieve his objective this week by running just 3 miles.

Answer: 656 square units

============================================================

Explanation:

Focus on the slanted side of the parallelogram, which is 26 units long. The opposite side to this is also 26 units long since opposite sides of any parallelogram are always congruent.

Now turn your attention to the triangle formed by that dashed line. Specifically this is a right triangle. It has a legs of x and 10, where x is the unknown height (also the height of the parallelogram). The hypotenuse of this right triangle is 26 units as mentioned in the previous paragraph.

Use the pythagorean theorem to find x

a^2+b^2 = c^2

10^2+x^2 = 26^2

100+x^2 = 676

x^2 = 676-100

x^2 = 576

x = sqrt(576)

x = 24

This is a 10,24,26 right triangle, which is based on the 5,12,13 right triangle (divide every part by 2)

-------------------

Now that we know the height of the parallelogram, the area is simply base times height

area of parallelogram = base*height = 32*24 = 768

Then we subtract off the area of the shaded gray rectangle, so we subtract off 7*16 = 112 to get 768 - 112 = 656 and this is the area of the unshaded region inside the parallelogram.

-------------------

Side note: The hypotenuse of 10*sqrt(2) you wrote down would only be correct if that dashed height line was 10 units.

The area of quadrilateral EDFG is approximately 21 cm²

What is the area of the Quadrilateral?

We are given that 3DE = 3FC = AB.

Thus:

The area of ΔFCB = ¹/₆ * the area of ABCD

Area of ΔFCB = ¹/₆ * 140 = 23.33 cm²

Area of ΔCFG/Area of ΔCED = (CF/CE)²

Side length of ABCD is: CD = √140 = 11.83 cm

FC = 1/3 * CD

FC = 3.944 cm

CE = √(DE² + CD²)

CE = √(3.944² + 11.83²)

CE = 12.47 cm

Area of ΔCFG/Area of ΔCED = (3.944/12.47)² = 1/10

Area of ΔCFG = 1/10 * 140/6 = 2.33 cm²

Audrey’s dog was 40 inches tall last year.it grows 4 inches this year.Select all the statements about Audrey’s dog that are true.

Answers

Audrey's dog is now 3 feet and 8.04 inches tall (since 0.67 feet is equal to 8.04 inches).

How tall is her dog in feet and inches?

First, we need to convert the height of Audrey's dog from inches to feet. Since 1 foot equals 12 inches, we can divide the height of the dog in inches by 12 to get its height in feet:

= 40 inches / 12 inches per foot

= 3.33 feet

Next, we will convert 4 inches that the dog has grown this year to its original height:

= 4 inches / 12 inches per foot

= 0.33 feet.

Total current height is :

= 3.33 feet + 0.33 feet.

= 3.66 feet.

Answers

The total amount spent was $11.40.

To find out how much was spent, we need to add up the cost of the first cup, the cost of the refills, and the cost of the bagel, and then subtract the discount. Here's how to do it step-by-step:

1. Start with the cost of the first cup: $4.25
2. Add the cost of the refills: $2.25 + $2.25 = $4.50
3. Add the cost of the bagel: $3.15
4. Add up the total cost so far: $4.25 + $4.50 + $3.15 = $11.90
5. Subtract the discount: $11.90 - $0.50 = $11.40

The admission fee at an amusement park is $4.00 for children and $5.80 for adults. On a certain day, 296 people entered the park, and the admission fees collected totaled 1472 dollars. How many children and how many adults were admitted?

Answers

Given;

Admission fee for children is, f(C) = $4.

Admission fee for adult is, f(A) = $5.80.

Total number of people is, N = 296.

Total fees collected is, F = $1472.

The objective is to find the number of children and number of adults.

Consider the childrens as C and the adults as A.

Then, first population equation can be written as,

\(C+A=296\)

Then, first cost equation can be written as,

\(4C+5.8A=1472\)

Solve the two equations by multiplying the first equation by 4.

\(\begin{gathered} 4C+4A=1184 \\ 4C+5.8A=1472 \end{gathered}\)

On solving,

\(\begin{gathered} -1.8A=-288 \\ A=\frac{288}{1.8} \\ A=160 \end{gathered}\)

Substitute the value of A in equation (1) to finf the value of C.

\(\begin{gathered} C+160=296 \\ C=296-160 \\ C=136 \end{gathered}\)

Hence, the number of children is 136 and the number of adult is 160.
