P=3a+2b2
Make a the subject of the formula

Answers

Answer 1

Answer: subtract 3a from both sides (will look like -3a+P=2b2) then subtract P (-3a=2b2-P) then divide both sides by -3

A circular piece of metal has a radius of 3.5 meters. The metal sells for $3.25 per square meter.

What is the total cost of the circular piece of metal?

A.
$11.38

B.
$38.47

C.
$71.44

D.
$125.01

Answers

Use the formula for finding the area of a circle, then multiply it by each square meter.

A = π r²
A = π (3.5)²
A = 12.25π
A = 38.485

C = 3.25(38.485)
C = 125.01

Answer = $125.01

Area of circle = πr²

Radius, r = 3.5m,

Area = πr² = π*3.5*3.5 = 12.25π m²

Area ≈ 12.25 *3.141 ≈ 38.477 m²

Since the metal sells for $3.25 per square meter.

Total cost for 38.477 m² = 38.477 * 3.25 = 125.05

Answer is = $125.05

The answer is not really there, but let's say we can manage option D which is $125.01.

What is the value of the expression? 19.2+(–7+3.8)a. 16
b. 24
c. 29
d. 30

Answers

$19.2+(-7+3.8)=19.2+(3.8-7)=19.2+(-3.2)\n\n=19.2-3.2=\huge\boxed{16}\leftarrow\boxed{a}$

The first thing I would do to solve this is do the () so -7+3.8=-3.2 +19.2=16 So your answer would be A. I hope this helps. :)

8 buttons are to 1 package as ? buttons are to 5 packages.20
30
40
50

Answers

8b = 1p (or p) (original statement)
To figure out how to get 5 packages, you multiply each side by 5
8b x 5 = 40b
1p (or p) x 5 = 5p
40b = 5p
So in conclusion, 40b (40 buttons) = 5p (5 packages)
Hope this helped!

40 buttons are to 5 packages

8/1 = x/5
multiply by 5 on both sides
x=40
