Answer:
14. 27
16. 170
Step-by-step explanation:
We must follow Order of Operations rules here. Work inside parentheses must be done first, then exponentiation, then multiplication and division, and finally addition and subtraction.
((5·7) - (8·4))³ becomes (35 - 32)³, or 3³, or 27.
16. 7² + ((46 - 7·2) + 2³)² becomes 7² + ((46 - 49) + 8)²
Again, do the work inside parentheses first:
7² + (3 + 8)² becomes 49 + 11², or 49 + 121, or, finally, 170

A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 16% are pennies and 30% are dimes. There are 4 more nickels than pennies. How much money does the bag contain?
Answers
Answer:
There is $5.93 in the bag
Step-by-step explanation:
50 coins
16% of 50 = 8 (pennies)
30% of 50 = 15 (dimes)
8 + 4 = 12 (nickels)
8 + 12 + 15 = 35 (total, without quarters)
Let's assume the rest are quarters, as no measurement of quarters is given.
15 quarters
Adding these up we get 593 cents, or $5.93
16% P:8 $0.08
24% N:p+4=12 $0.60
30%- D:15 $1.50
30% Q:15 $3.75
$.08+.6+1.5+3.75=$5.93

Step-by-step explanation:

Answer and Step-by-step explanation:
When angles are complementary, it means that, when added together, will equal 90 degrees.
To find the missing angle, we subtract 37 from 90.
90 - 37 = 53.
The measure of the other angle is 53⁰.

4 multiplied by the sum of y and 7 is equal to 16
Answers
Make sure the makes sense so 4 is going to be first because it’s 4 outside of (y+7) so once you do y+7 you multiply by 4 then that should equal 16
The equation that represents 4 multiplied by the sum of y and 7 is equal to 16 is 4(y + 7) = 16 and the value of y = - 3
How to form equation ?The problems says 4 multiplied by the sum of y and 7 is equal to 16.
Therefore,
The sum of y and 7 is represented as follows:
y + 7
4 multiplied by the sum of y and 7 is as follows:
4(y + 7)
4 multiplied by the sum of y and 7 is equal to 16 is as follows:
4(y + 7) = 16
4y + 28 = 16
subtract 28 from both sides
4y = 16 - 28
4y = -12
y = -12 / 4
y = -3

can someone plz help me with this math problem and plz explain how you got your answer
Answers
Answer:
Well for these problems you need to know the formula so
First off we have to square the radius thats just a fancy way of saying multiply by itself so 2.8 x 2.8 = 7.84 Now we just multiply that by pi!
so 3.14 x 7.84 = 24.6176 now sense we have to round it our final answer would be 24.6
Pii * radius*radius (note: * this start symbol means multiply if you don’t know)
All we have to do is substitute in the values.
Steps:
1. 3.14 * 2.8 * 2.8
2. Answer: 24.617
3. Now we have to round them to the nearest tenth.
So the answer rounded will be: 24.62 yd (squared)
Hope this helps you!!

Answers
Answer:
1,800
Step-by-step explanation:
V = l × w × h
V = 15 × 12 × 10
V = 180 × 10
V = 1,800 ft
Step-by-step explanation:
The volume of a box is equal to the length l times the width w times the height h.
[tex]lenght \times width \times height[/tex]
Substitute the values of the length l=10, the width w=15, and the height h=12 into the formula.
[tex]10 \times 15 \times 12[/tex]
Multiply 10 by 15.
