Calculate the perpendicular height. (h)
Hence calculate the area of the triangle.

Answer:

Step-by-step explanation:

surface area of cuboid=2(lb+bh+hl_

=2(7*4+4*5+5*7)

=2(28+20+35)

=2*83

=166 mm^2

Given figure is cuboid so use surface area of cuboid formula.

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

This is a triangular prism

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:

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.

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:

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:

∠Y is the smallest angle measure.

The correct answer is B

Answer:

1.5

Step-by-step explanation:

Since the two triangles are similar ,

So that ,

→ a/b = 2.1/1.4

→ a/b = 3/2

Hence the required answer is 1.5

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:

D

Step-by-step explanation:

I did it too

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:

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.
