Draw the dilation of ABCD using center D and scale factor 1/3. Label the dilation EFGH

Answer:

Step-by-step explanation:

Given

Area of the rectangle =Length × width

Given

The desired length of the lot is 6 m longer than its width, then L = 6+W

A = LW

40 = (6+W)W

40= 6W+W²

W²+6W -40 = 0

W²+10W-4W-40 = 0

W(w+10)-4(w+10) = 0

W+10 = 0 and w-4 = 4

W = -10 and w = 4

Width can't be negative

W = 4m

Since L = 6+w

L = 6+4

L = 10m

Hence the possible dimension s 4m by 10m

Answer:

The value of x is -3

Step-by-step explanation:

∵ ∠A and ∠B are vertical angles

→ By using the rule above

∴ m∠A = m∠B

∵ m∠A = (3x + 26)°

∵ m∠B = (x + 20)°

→ Equate their measures

∴ 3x + 26 = x + 20

→ Subtract x from both sides

∵ 3x - x + 26 = x - x + 20

∴ 2x + 26 = 20

→ Subtract 26 from both sides

∵ 2x + 26 - 26 = 20 - 26

∴ 2x = -6

→ Divide both sides by 2

∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{-6}{2}[/tex]

∴ x = -3

∴ The value of x is -3

Answer:

y=-4x-6

Step-by-step explanation:

use the formula y=mx+b

oh btw i just posted a question so please maybe help with it???

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex]y - 6 = - 4(x + 3)[/tex]

[tex]y - 6 = - 4x - 12[/tex]

Add sides 6

[tex]y - 6 + 6 = - 4x - 12 + 6[/tex]

[tex]y = - 4x - 6[/tex]

This is the slope-intercept form.

Done...

Answer:

9 2/3

Step-by-step explanation:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Answer:

$4.94

Step-by-step explanation:

To find out the change from $20, we need to find her total cost.

Total cost = 2.25lbs * $4.96/lb + 0.75lbs * $5.20/lb

Total cost = $11.16 + $3.90 = $15.06

Now $20 - total cost = $20 - $15.06 = $4.94

Fiona must deposit  $18,277.65 into her retirement account each year for the next 20 years in order to have a total of $600,000 by the time she retires.

percentage, a relative value indicating hundredth parts of any quantity.

The present value of an annuity is:

PV = PMT x [(1 - (1 + r)⁻ⁿ) / r]

Where PV is the present value,

PMT is the periodic payment

r is the interest rate per period (6% per year), and

n is the number of periods (20 years).

We want to find PMT, so we can rearrange the formula to solve for it:

PMT = PV x [r / (1 - (1 + r)⁻ⁿ)]

We know that PV is $600,000, r is 6% or 0.06, and n is 20.

Plugging these values into the formula, we get:

PMT = $600,000 x [0.06 / (1 - (1 + 0.06)⁻²⁰)]

PMT ≈ $18,277.65

Therefore, Fiona must deposit  $18,277.65 into her retirement account each year for the next 20 years in order to have a total of $600,000 by the time she retires.

Answer:

irst, 4865 rounded to the nearest ten is:

4870

Step-by-step explanation:

Here we will tell you what 4865 is rounded to the nearest ten and also show you what rules we used to get to the answer.

Remember, we did not necessarily round up or down, but to the ten that is nearest to 4865.

When rounding to the nearest ten, like we did with 4865 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

It's really easy to solve this problem all you have to do is long division with 4,274 and 51.

4,274 divided by 51 is = to 83 but it still has decimals leftovers meaning there would be a remainder and since we already found out 81 is part of the answer we know it won't be 91 and it has to be 83 with a remainder!

Answer: $0.75

Step-by-step explanation:

To solve this problem, we can create 2 equations. Let's use x for tacos and y for soda.

Equation 1: 5x+y=13.25

Equation 2: x=2.5

Since we know the value of x, we can plug it into Equation 1 to solve for y.

5(2.5)+y=13.25        [multiply]

12.5+y=13.25           [subtract both sides by 12.5]

y=0.75

Now, we know the price of the soda is $0.75.

Answer:

The soda costs $0.75.

Step-by-step explanation:

We are given that Ms. Hogan paid $13.25 for 5 tacos and one soda. We are also given that one taco costs $2.50. Therefore, we can set up a system of equations to solve for how much a soda costs.

[tex]\displaystyle\left \{ {{5x + y = \$13.25} \atop {x = 2.50}} \right.[/tex]

This is our required system of equations. We are given that one taco costs $2.50, so this is our x. Therefore, the price of one soda is y.

We can use the second equation and substitute it in place of the x in the first equation to solve for the price of the soda.

[tex]\displaystyle5x+y=\$13.25\\\\5(2.50)+y=\$13.25\\\\12.5 + y = \$13.25\\\\y = \$0.75[/tex]

Therefore, one soda costs $0.75.

Answer:

Look below :)

Step-by-step explanation:

1. coefficient

2. constant (it's referred to as a constant because the value never changes)

3. This polynomial has 4 terms. We know this by counting them. 5x^3 is one term, -x^2 is the second term, 5x is the third term, and -8 is the fourth term.

4. In descending order: 2, 1, 3, 4. The degree is the same value as the exponent. For the last term, x^2y^2, you add the values of the exponents together to get the degree.

5. -2 is the coefficient. The term with the third degree, or has 3 as the exponent, is -2x^3.

6. 1 is the coefficient. The term with the second degree is x^2. When the coefficient is 1, usually the 1 isn't written because any number multiplied by 1 equals that number (x * 1 = x)

7. 5 is the degree of the polynomial. To find the degree of a polynomial, find whichever term has the highest value for an exponent. In this case, 5 is the highest exponent.

8. 2 is the degree of this polynomial. Although none of the terms may look like they have a degree of 2, in order to find the actual degree of 4xy you have to add the values of the degree of x and y to find the actual degree. If x and y both have a degree of 1, you add those together to make 2.

9. 2[tex]x^{3}[/tex] - 7[tex]x^{2}[/tex] + 5x - 15. To order a polynomial from highest to lowest you have to order the terms in decreasing value of their exponents.

10. -4[tex]x^{3} y[/tex] + 2xy + 5x + 7.

I hope this helps :)
