Solve the equations to find the value of the variable using inverse operations.
a.) 4y = 248 b.) c + 2/5 = 2

Answers

Answer 1

Answer:

a), y=62       b.) c=1 3/5 or 8/5

Step-by-step explanation:

Okay so these are fairly simple lets start with A

4y=248, all we have to do is divide 4 on both sides

4y/4=y

248/4=62

Pretty Simple

For b just subtract 2/5 from both sides

(c+2/5)-2/5=c

2-2/5=1 3/5 or 8/5

Four more than the product of 2 and a

Answers

Four more than the product of 2 and a:

4+2a

Answer:

2a + 4

Step-by-step explanation:

The key word, "product," means you're multiplying, and since it says the "product of 2 and a," you're multiplying 2 and a. To simplify that, you can write 2a (which is equal to 2 · a).

Since it says four more (key word is more), you need to add four to 2a. Since if you have "less than" or "more than", the product will be before the number we're adding, leaving you with  2a + 4.

A 471.2in2
B 10in2
C 150in2
D 4712.3in2

Answers

Answer:

A. 471.2 in²

Step-by-step explanation:

Cylinder volume:

V = πr²h

Cylinder surface area:

A = 2πr(r + h)

Find h from the first equation:

h = V/(πr²) = 785.4/(3.14*5²) = 10 in

Find surface area:

A = 2π(5)(5 + 10) = 471.23 in²

Correct choice is A

Answer:

volume of cylinder=πr²h

785.4=22/7×5²×h

h=785.4×7/(22×25)=9.99=10in

Step-by-step explanation:

surface area of cylinder =2πr(r+h)=2π×5(5+10)=

Answer:

Step-by-step explanation:

f(x)=x³+2x²-7x+4

at x=1

f(1)=1³+2(1)²-7(1)+4=1+2-7+4=0

so x=1 is one zero.

1) 1   2  -7  4

___________

x²+3x-4=0

x²+4x-x-4=0

x(x+4)-1(x+4)=0

(x+4)(x-1)=0

x=-4,1

zeros are -4,1,1

Kayla studied data collected on the school basketball team for one season. She noticed that a player on the team had 13 successful free throws out of a total of 20 attempted free throws. What percent is that?

Answers

If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100.  When she solves the problem, m=65%.

13/20 is part out of whole.  The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable.  Thus we have

13/20 = m/100

Cross multiply:

20*x = 13*100

20x = 1300

Divide both sides by 20:

20x/20 = 1300/20

x = 65

Need help plz?????????!!!!!!

Answers

Answer:

93°

Step-by-step explanation:

By exterior angle theorem:

(4x + 9)° = 2x° + (3x - 12)°

(4x + 9)° = (2x + 3x - 12)°

(4x + 9)° = (5x - 12)°

4x + 9 = 5x - 12

4x - 5x = - 12 - 9

-x = - 21

x = 21

Measure of exterior angle

= (4x + 9)°

= (4*21 + 9)°

= (84 + 9)°

= 93°
