Answers

Answer 1

Answer:

528 in.²

Step-by-step explanation:

Surface area of the figure = (surface area of the smaller rectangular prism + surface area of the bigger prism) - area of 1 of the base of the smaller rectangular prism

✔️Surface area of the bigger rectangular prism = 2(WL + HL + HW)

= 2(10*12 + 5*12 + 5*10) = 2(120 + 60 + 50)

= 2(230)

Surface area of bigger rectangular prism = 460 in.²

✔️Surface area of the smaller rectangular prism = 2(WL + HL + HW)

= 2(2*2 + 8*2 + 8*2) = 2(4 + 16 + 16)

= 2(36)

Surface area of smaller rectangular prism = 72 in.²

✔️area of 1 of the base of the smaller rectangular prism = L*W = 2*2 = 4 in.²

✅Surface area of the figure = (460 + 72) - 4

= 532 - 4

= 528 in.²

Choose 3 values that would make this inequality true. 7n ≤ 21

Answers

Answer:

A couple could be 2, 1, or even a decimal 1.3 as an example.

Step-by-step explanation:

Divide both sides by 7:

7n/7 < 21/7

n < 3

Any value of n less than 3 will make the inequality true, so just pick three values (numbers) for n that are less than 3, such as n = 2.

Which is a better deal on a $10 item:

Answers

50% off. You only have to pay $5. If you do 10% off one time you have to pay $9 and then the next time you get 40% off, you’d have to pay $6.

Unless I completely misunderstood, 50% should be better. If it’s 40% off + 10% then it will be 50% and therefore both of them are equal deals and both good.

a train travels 16 miles in 20 minutes how many minutes would 12 miles be

Answers

Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.

Step-by-step explanation:

16 miles     =  12 miles

20 mins.        how many mins?

16    =   12       cross multiply       16? = 240   divide by 16     240 divided by 16 = 15 miles

20          ?                                                                                because 15 x 16 = 240

Answer:

It will take 15 minutes to travel 12 miles.

The length of a rectangle is 9” greater than the width. The area is 36”2. Find the dimensions

Answers

Answer:

Step-by-step explanation:

L = W+9

area = LW = 36

(W+9)W = 36

W²+9W-36 = 0

W = -12, 3

-12 is an extraneous solution, so W = 3 inches

L = W+9 = 12 inches

Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1​

Answers

Given:

The expression are

(i) [tex]5x-3[/tex]

(ii) [tex]11-2y^2[/tex]

(iii) [tex]2x-1[/tex]

To find:

The terms which are not constants and their numerical coefficients.

Solution:

Constants: The terms which are free from variables.

Numerical coefficient: Number multiplied with a variable.

(i) [tex]5x-3[/tex]

Constant = -3

Term which is not constant = 5x

Numerical coefficient = 5

(ii) [tex]11-2y^2[/tex]

Constant = 11

Term which is not constant = [tex]-2y^2[/tex]

Numerical coefficient = -2

(iii) [tex]2x-1[/tex]

Constant = -1

Term which is not constant = 2x

Numerical coefficient = 2

Therefore, the terms which are not constants are  [tex]5x,-2y^2,2x[/tex]  respectively and their numerical coefficients are 5, -2, 2 respectively.
