Question
enot [183]

Answer:

The percent increase in pay is 50%.

Step-by-step explanation:

We need to find the percent increase from $24 to $36.

To solve this, we first must ask ourselves the question

36 is what percent of 24?

Y = P% of 24

36 = X · 24

To get X alone, we divide 36 by 24. That's 1.50. So now we know 36 is 150% of 24. Knowing 24 is 100%, we can find the percent increase. Well, how do we get from 100% (24) to 150% (36)? By increasing by 50%. Therefore, the percent increase in pay is 50%.

Find the value of x in the figure
Alex17521 [72]

Answer:

70degrees

Step-by-step explanation:

Using the theorem;

Angle at the vertex is the half of the difference of the angles at its intercepted arcs

Angle at the vertex = 24 degrees

difference of the angles at its intercepted arcs = 118 - x

According to the theorem;

24 = 1/2(118 - x)

Cross multiply

24 * 2 = 118 - x

48 = 118 - x

x = 118 - 48

x = 70degrees

Hence the value of x is 70degrees

A^2+b^2=????????????????????????
zepelin [54]

What you have written here is an equation.

You can define as

a2+b2=y  

If you want to derive a^2+b^2 from ( a+b)^2

(a+b)2=a2+b2+2ab  

Ora2+b2=(a+b)2−2ab

Given the binomials (x - 3), (x - 1), (x + 2), and (x + 3), which one is a factor of f(x) = 2x3 + 3x2 - 2x - 3?
spayn [35]

Answer:

(x-1) is factor of our function.

Step-by-step explanation:

We are given a function f(x)=2x^{3} +3x^{2} -2x-3 and we are asked to find the correct factor from the given options.

Let us factor out our polynomial.

2x^{3} +3x^{2} -2x-3

x^{2} (2x+3)-1(2x+3)

(x^{2} -1)(2x+3)

(x+1)(x-1)(2x+3)

Therefore, (x-1) is correct choice for factor of our polynomial.

Lucy makes 4/7 of a dress in 3/4. How many dresses does she make in one hour
GREYUIT [131]

Answer:

3/7 of a dress in one hour

Step-by-step explanation:

(4/7)/(3/4)=x/(4/4)

(4/7)(4/3)=x/1

cross product

4/3*x=(4/7)(1)

4/3x=4/7

x=(4/7)/(4/3)

x=(4/7)(3/4)

x=3/7
