Step-by-step explanation:

I took the test, :D-|--=:

Answer:

b

Step-by-step explanation:

first, figure out the radius. the radius is the 1/2 of the diameter, so 5. in the equation, the formula is pi x radius^2. so 5^2 is 25. then 25x3.14 is b, and we have our answer.

Answer:

b

Step-by-step explanation:

10 divided by 2=5 radius

to get area = Radius^2 x pi

5x5x3.14= 78.5 square units

Answer:The difference between the medians is 2.5

Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5

Answer: The division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.

The division is an operation inverse of multiplication. If 3 groups of 4 make 12 in multiplication; 12 divided into 3 equal groups give 4 in each group in division.

The main goal of the division is to see how many equal groups or how many in each group when sharing fairly.

For example:

There are 16 balls and 4 boxes, how to put 16 balls into four equal sized boxes?

Step-by-step explanation:  Therefore, 4 balls should be kept in each box.

Mathematical notation for division

There are various signs which can be used to indicate division such as ÷, /.

For example:

8 ÷ 2

8/2

Special names for each character in Division

Each part involved in a division equation has a special name.

Dividend ÷ divisor = quotient

Dividend: The dividend is the number that is being divided in the division process.

Divisor:The number by which dividend is being divided by is called divisor.

Quotient: A quotient is a result obtained in the division process.

 18    ÷   3    =    6

image5       image4       image6

Dividend        divisor         quotient

So, in the above process where we divided 16 balls into 4 equal groups;

The dividend is 16, the divisor is 4 and thus the quotient is 4.

Answer:

Step-by-step explanation:

There are three main parts to a division problem: the dividend, the divisor, and the quotient. The dividend is the number that will be divided. The divisor is the number of “people” that the number is being divided among. The quotient is the answer.

First step to simplifying ratios is to find the ratio. The ratio would be 14:16. The next step is to find the least common factor and simplify by dividing. The least common factor is 2, so divide both numbers by 2.

[tex]\frac{14 / 2}{16 / 2} = \frac{7}{8}~or~7:8[/tex]

With that info, your answer is 7:8

Answer:

50⁰

Step-by-step explanation:

we know that sum of angles in a triangle is equal to 180⁰

on adding the angles we get

x⁰+x⁰+20⁰+x⁰+70⁰=180⁰

3x⁰+90⁰=180⁰

3x⁰=90⁰

x⁰=30⁰

Now angle R=x+20=30+20=50⁰

Answer is 50⁰

Step-by-step explanation:

Answer:

29.5 inches squared

Step-by-step explanation:

The formula for the area of a trapezoid is [tex]\frac{base1 + base2 * height}{2}[/tex],

so base1 = 14 inches and base2 = 30 inches

since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches

then, 14+30+15=59 and 59/2=29.5

therefore, your answer would be 29.5 inches squared

Answer:

-2, -1, 0, 1, 2

Step-by-step explanation:

2/2=1

4/2=2

Answer:

angle 2=120°

angle 1=60

Step-by-step explanation:

70+50=120

or

180-(70+50)=60

angles on a straight line add up to 180°

180-60=120

Answer:

The best name for the shape of his kite is a rectangular rhombus.

Step-by-step explanation:

Answer:

1 pound is 16 oz

so 1/2 pound is 8 oz

So 3 1/2 pounds as whole pounds and ounces would be:

3 pounds and 8 ounces

and/or

3 lbs. and 8 oz.

Answer:

x = 40

Step-by-step explanation:

(3x + 5) + (x + 15) = 180

3x + 5 + x + 15 = 180

4x + 20 = 180

      -20    -20

4x = 160

÷4      ÷4

x = 40

your welcome and pls give me the brainliest

Let's simplify these ratios:-

1. 3:9

Divide both sides by 3:-

1:3

 2. 9:27

Divide both sides by 9:-

1:3

  3. 2:4

Divide both sides by 2:-

1:2 (Option C)

 4. 30:90

Divide both sides by 30:-

1:3

Step-by-step explanation:

The four longest pieces are the four X’s on the farthest right.

These X’s have values of 12.75, 12.75, 12.75, and 13.

12.75 + 12.75 + 12.75 + 13

25.5 + 12.75 + 13

38.25 + 13

51.25

Answer:

35

Step-by-step explanation:

Steps

1.  5x + 105 = 8x because you distributed the 5

2. 105 = 3x because you subtract the 5x on both sides

3. 105/3 = x because you divide the 3 and 105/3 is 35

Answer:

weight in an elevator must be less than 2000 lbs goes with w < 2000

a ton is 2000 lbs goes with w = 2000

the pool must hold at least 2000 gallons goes with w ≥ 2000

the scale can hold up to and including 2000 lbs goes with w ≤ 2000

my car weighs more than 2000 lbs goes with w > 2000

Step-by-step explanation:

If the weight is less than 2000 lbs, then the inequality will have a lesser than sign. The choice that matches is w < 2000.

If a ton is exactly 2000 lbs, then it's equal to 2000. In other words, the inequality will have an equal sign. The choice that matches is w = 2000.

If a pool should be held with at least 2000 lbs, then it's weight is either greater than or equal to 2000 lbs. the choice that matches is w ≥ 2000.

If a scaled can hold up to, including 2000lbs, then the maximum weight it can hold is 2000 lbs. The weight is less than or equal to 2000. the choice that matches is w ≤ 2000.

If a car weighs more than 2000 pounds, then the weight will be greater than 2000. The choice that matches is w > 2000.

Answer:

C

Step-by-step explanation:

because angles a is diagonally opposite to 162, they are equal. And as b and 162 are alternate angles, they will also be equal

Answer:

C. <A & <B

Explanation:

If lines m and n are parallel, then you can use the proofs of vertical angles are congruent and alternate interior angles are congruent to prove that <A and <B are equal to 162 degrees; the reason that <C and <D are not congruent, is because they would be too small to fit 162 degrees, they would be the opposite of 162 which is 180-162=18 degrees.
