Question 2
64 is 40% of what number?
А
128
B
256
160
D
26

Answers

C: 160 is the correct answer

Answer:

answer is 160

Step-by-step explanation:

1. We assume, that the number 40 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 40, so we can write it down as 100%=40.

4. We know, that x% equals 64 of the output value, so we can write it down as x%=64.

5. Now we have two simple equations:

1) 100%=40

2) x%=64

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=40/64

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 64 is what percent of 40

100%/x%=40/64

(100/x)*x=(40/64)*x    

100=0.625*x

100/0.625=x

160=x

x=160

now we have:

64 is 40% 160

Sara has $1.30 less than double what Billy does. Sara has $53.72. How much money does Billy have?​

Answers

Answer:

Billy has $27.51

Step-by-step explanation:

First let's set up an equation to solve this problem.

Assign a variable to Billy's amount. Let's make it x.

Then we just interpret the problem and solve:

2x - 1.30 = 53.72

     +1.30    +1.30

----------------------------

2x = 55.02

(Divide by 2 on both sides)

----------------------------

x = $27.51

2x = Billy's amount doubled

2x - 1.30 = Taking away 1.30 from double Billy's amount

53.72 = Sara's amount

Answer:

E. √39

Step-by-step explanation:

see attached

From the similar triangles value of x is √39. Therefore, option E is the correct answer.

From the given triangle, CD=13, BD=3 and AD=x.

Given that, ΔABD is similar to ΔCAD.

CD/AD = AD/BD

13/AD = AD/3

39 = AD²

AD = √39 = x

Therefore, option E is the correct answer.

which equation shows P=2l + 2w when solved for w?

A. w= 2l/P
B. w= 2l-P/2
C. w=2l - p/2
D. w=p-2l/2​

Answers

Solving for w by making w the subject of the formula, we would have: D. w = (P - 2l)/2.

Change of Subject of Formula

To make a variable a subject of the formula, we solve for the variable.

Given the equation, P=2l + 2w, we are required to solve for w.

Thus:

P = 2l + 2w

Subtract both sides by 2l

P - 2l = 2w

Divide both sides by 2

(P - 2l)/2 = w

w = (P - 2l)/2

Therefore, solving for w by making w the subject of the formula, we would have: D. w = (P - 2l)/2.
