Answer:

true

Step-by-step explanation:

im pretty sure its true

Answer:

actually it's false because to find the mode you find the number that occurs most often. In this case it's 8.

2) 6.5

the sum of numbers/ number of them

Answer:

216 cm squared

Step-by-step explanation:

14*12 for rectangle area=168  because of l*w

for the triangle: 12 * 8 =96/2=48 because of A=1/2 * b*h

area equals 168+48=216 cm squared

Answer:

3rd Option

Step-by-step explanation:

Volume = (2x-5)*(2x+5)*3x

Volume = (4x^2 + 10x - 10x -25)*3x

Volume = 12x^3 +30x^2 -30x^2 - 75x

Volume = 12x^3 - 75x

The expressions represent the volume of the prism is

V = 12x^2 - 75x

The formula for calculating the volume of rectangular prism is expressed as:

V = lwh

l is the length

w is the width

h is the height

Given the following

l = 2x + 5

w = 2x - 5

h = 3x

V =  3x(2x+5)(2x-5)

V = 3x(4x^2 - 25)

V = 12x^2 - 75x

Hence the expressions represent the volume of the prism is

V = 12x^2 - 75x

Answer:

3.04

Step-by-step explanation:

Answer: D 90

Step-by-step explanation:

One way to do this follows:  Find the ratio, r, which when multiplied by each of the four numbers in the ratio produces the actual number of parts present:

4r + 11r + 9r + 6r = 60

Summing these up results in 30r = 60, so r is 2.

There are 4(2), or 8, nails,

11(2), or 22, screws,

9(2), or 18, washers, and

6(2), or 12, brackets.

Note that 8 + 22 + 18 + 12 = 60 (total number of parts)

If 5 carpenters have identical boxes, there will be 5(18), or 90, total washers.

Answer:

Paper Lanterns: 4

Bags of Balloons: 12

Garlands: 11

Banners: 4

Step-by-step explanation:

Cost of lanterns is $6.50

Mrs. Murphy bought 4 lanterns

Multiply the cost of one lantern ($6.50) by the number of lanterns bought (4)

6.50 multiplied by 4 equals 26

Cost of banners is $5.25

Mrs. Murphy bought 4 banners

Multiply the cost of one banner ($5.25) by the number of banners bought (4)

5.25 multiplied by 4 equals 21

Mrs. Murphy bought 3 times as many balloons as she did lanterns

So, you multiply the number of lanterns bought (4) by 3

This gives you 12

You then multiply the cost of each balloon ($5.00) by the number of balloons bought (12)

5.00 multiplied by 12 equals 60

Mrs. Murphy bought 7 more garlands as she did lanterns

So, you add 7 to the number of lanterns bought (4)

7 plus 4 equals 11

To find the cost of the total garlands bought

You multiply the cost of each garland ($3.50) by the number of garlands bought (11)

3.50 multiplied by 11 equals 38.5

Now you can add up the costs of all the items

26+21+60+38.5=145.50

145.50 was the total amount she spent so you know it is the correct answer.

Answer:

∠Y is the smallest angle measure.

The correct answer is B

Answer:

5. D  6. B   7. C

Step-by-step explanation:

All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.

The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.

Answer:

Mean: 46 Median: 45 Mode: 45

Step-by-step explanation:

Mean: 41+45+39+56+48+45+42+34+47+62+35+58 = 552 then, 552/12 = 46

Median: Put numbers in order from least to greatest and cross one out on each side until you get to the middle number. 45 and 45 were the last two numbers to be crossed out, the middle of those would simply be 45!

Mode: 45 appears twice while the rest of the numbers only appeared once.

Answer:

Measure of angle R:                      Measure of angle S:

42 degrees                                     90 - 42 = 48

30 degrees                                     90 - 60 = 30

84 degrees                                     90 - 84 = 6

Complimentary angles are angles whose sum is 90 degrees

Answer:

The numbers are 44 and 36

Step-by-step explanation:

n + n - 8 = 80

2n - 8 = 80

2n (- 8 + 8) = 80 + 8

2n = 88

2n/2 = 88/2

n = 44

44 - 8 = 36

Answer:

The missing number is 2

Step-by-step explanation:

43 - 13 = 30

13 - 10 = 3

10 - 8 = ?

10 - 8 = 2

30 - 3 = 27

3 - ? = 1

3 - 1 = 2

3 - 2 = 1

? = 2
