The answer is 86

Following PEMDAS, which is:

parentheses

exponents

multiplication

division

addition

subtraction

I found that the answer was 86

Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

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

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

B.Obtuse isosceles triangle
C. Right isosceles triangle
D Right scalene triangle

Answers

It is a right isosceles triangle, C

A triangle with two sides of equal length and the angle where these two sides meet is 90° is Right isosceles triangle. Therefore, option C is the correct answer.

What is a right triangle?

A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.

A right triangle with two equal-length legs is called an isosceles right triangle. The corresponding angles would also be congruent because the lengths of the two legs of the right triangle are equal. As a result, the two acute angles and two legs of an isosceles right triangle are congruent.

Therefore, option C is the correct answer.

a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.

b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.

Use the information to answer the following question.

The bottom of a swimming pool is 10 feet below the surface of the water in the pool. The surface of the water is represented by the number 0, and the bottom of the pool is represented by the number -10. The pool’s diving board is the same distance above the surface of the water as the bottom of the pool is below the surface of the water.

What number represents the location of the diving board?

A.
20

B.
0

C.
10

D.
1/10

Answers

Answer:

C

Step-by-step explanation:

Since the difference between 0 and -10 is 10, this means that the difference between the diving board and the pool also has to be 10. Therefore, the diving board is 10 feet above the water since 0+10 is 10.

C. since it’s above the surface of the pool which is 0 it’s at a positive elevation of 10

There are 8 boys for every 3 girls at a concert. If there are 220 people at the concert, what is the difference between the total number of boys and girls at the concert?

Answers

Answer:

100

Step-by-step explanation:

First we get the ratio of 8:3 for the amount of boys to girls.

Assuming there are no other parts,

the Whole = A + B is the denominator:

Whole = 8 + 3 = 11

Part A = 8 and Part B = 3 are numerators for each fraction.

The fractions are then:

8/11 and 3/11

8/11 for boys

and 3/11 for the girls

Now we just multiply 220 by these fractions:

220 * 8/11 = 160

220 * 3/11 = 60

Then subtract:

160 - 60 = 100

Answer:

There are 60 girls and 160 boys
