Answer:

d

Step-by-step explanation:

Answer:

d = ab / ec

Step-by-step explanation:

ab / c = d x e

times both sides with c:  ab = d x e x c

divide both sides with e x c:  ab / ec = d

Answer:

y=5/2x-1

Step-by-step explanation:

Choose two coordinates. I will choose the ones you chose, (-2, -3) and (0, 1).

Find the slope first using the slope equation: [tex]\frac{y2-y1}{x2-x1}[/tex]

y2 is 1, y1 is -3, x2 is 0, and x1 is -2.

[tex]\frac{1-(-3)}{0-(-2)}[/tex]

[tex]\frac{1+3}{0+2}[/tex]

[tex]\frac{4}{2}[/tex]

m = [tex]2[/tex]

The slope is 2.

Now that we found out the slope, we can start to assemble our equation. The m in the equation y = mx + b stands for the slope.

Now the equation is: y = 2x + b.

We need to figure out the y-intercept next. The b in the equation stands for the y-intercept. Choose one coordinate. I will chose (0, 1). x = 0 and y = 1. Substitute 0 in for x and 1 into y.

y = 2x + b

1 = 2(0) + b

1 = 0 + b

1 = b

Now we know what b is. Plug in 1 for b in the equation.

y = 2x + 1

I hope this helps! Let me know if I got something wrong and I'll fix it.

Answer:

Your answer would be 189

Step-by-step explanation:

if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.

Answer:

t = 1

Step-by-step explanation:

5t + 8 = 13

Subtract 8 from both sides

5t + 8 - 8 = 13 - 8

5t = 5

Divide both sides by 5

5t/5 = 5/5

t = 1

Check:

5t + 8 = 13

5(1) + 8 = 13

5 + 8 = 13

Step-by-step explanation:

-13x - 15 = -93

-13x = -78

x = 6

Answer:

1.17

Step-by-step explanation:

(MUCH BETTER!)

From the definition of the sin of an angle, you know:

sin(45°) = AC/AB = 4/AB   ⇒   AB = 4/sin(45°) ≈ 5.6569

sin(63°) = AC/AD = 4/AD   ⇒   AD = 4/sin(63°) ≈ 4.4893

Then the difference AB-AD is:

AB -AD = 5.6569 -4.4893 = 1.1676

AB -AD ≈ 1.17 units

Answer: 10 and a half For ivy For Hayden 8 half

Step-by-step explanation: because ivy gave Her mother 2 each and her father half and for her brother

Answer:

Given to father by Ivy: 12/2=6

Given to father by Hayden: 10/2=5

Now,

Chocolates given to mother by Ivy: 2

Chocolates given to mother by Hayden: 2

Now total chocolates given by Ivy to mother and father: 6+2 = 8

Now total chocolates given by Hayden to mother and father: 5+2=7

Now total chocolates left  with Ivy 12-8=4

Now total chocolates left with Hayden: 10-7= 3

Thus ivy and Hayden has  4&3 chocolates respectively

Answer:

A.

Step-by-step explanation:

Hi there!

By factoring the trinomial, we end with (x-9)(x-4)

However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.

0 = x - 9

0 = x - 4

Using orders of operations, x = 9 and x = 4

Therefore,  A is your answer.

I hope this helps!

Answer:

26 months i believe is correct :)

Step-by-step explanation:

The number of years it will take to pay off the loan will be  4.125 years based on simple interest.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

As per the given,

Total loan = $1125

Rate of interest R = 10%

Monthly payment = $25

Yearly payment = 25 x 12 =$300

Suppose it takes T years,

Total amount A = principle P + interest

A = 1125 + 10% of 1125

A = 1125 + 0.10 x 1125

A = $1237.5

The number of years it will take will be as follows,

Total amount / yearly payment

⇒ 1237.5/300

⇒ 4.125 years.

Hence"The number of years it will take to pay off the loan will be  4.125 years based on simple interest".

Answer:

New area by scale of 1.5 = 81 in²

Step-by-step explanation:

Given:

Current area  = 36 in²

Find:

New area by scale of 1.5

Computation:

New area by scale of 1.5 = Current area x (scale factor)²

New area by scale of 1.5 = 36 x (1.5)²

New area by scale of 1.5 = 36 x (2.25)

New area by scale of 1.5 = 81 in²

Answer:

B.

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5.

We are asked to find the area of the enlarged trapezoid. The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

Therefore, the area of the enlarged trapezoid would be  and option B is the correct choice.
