Answer:

John and Shawn spent the same number of hours after [tex]4[/tex] weeks.

Step-by-step explanation:

Number of hours already completed by John to his volunteer project [tex]=40[/tex] hours

Number of hours spent by John each week to his volunteer project [tex]=5[/tex] hours

Number of hours spent by Shawn each week to his volunteer project [tex]=15[/tex] hours

Suppose John and Shawn spent the same number of hours after [tex]x[/tex] weeks.

Therefore,

[tex]40+5x=15x[/tex]

[tex]40=15x-5x\\40=10x[/tex]

[tex]x=4[/tex] weeks.

So,

John and Shawn spent the same number of hours after [tex]4[/tex] weeks.

Answer:

w⁴+5w³+17w²+24w +18

Step-by-step explanation:

Area of a rectangle = length * width

Given

Length  = w²+3w+9

width = w²+2w+2

Area of the rectangle = (w²+3w+9)(w²+2w+2)

Area of the rectangle = w²(w²) + 2w(w²) + 2w² + 3w(w²) + 3w(2w) + 2(3w)+9w²+9(2w)+9(2)

Area of the rectangle = w^4+2w^3+2w²+3w^3+6w^2+6w+9w²+18w+18

Collect the like terms;

Area of the rectangle = w^4+2w^3+3w^3+2w²+6w²+9w²+6w+18w+18

Area of the rectangle = w⁴+5w³+17w²+24w +18

Hence the area of the entire triangle is w⁴+5w³+17w²+24w +18

Answer:

212 meters

Step-by-step explanation:

The diagonal of a square is the square root of 2 times the length of the square. This can be rewritten as the square root of (2*area)

2 * 22500 = 45000

The square root of 45000 is about 212.13, which would round down to 212 meters.

Answer:

p/2 - 25 = 150

Step-by-step explanation:

I'll try my best.

$150 would be the initial value, so we would use that for the base.

$25 less means subtract 25 dollars in this context.

2 times means multiply by 2.

"$150 was $25 less than 2 times the amount he paid for it ([tex]p[/tex])."

[tex]\frac{p}{2} -25 = 150[/tex]

If you were to solve this:

[tex]\frac{p}{2} -25 = 150[/tex]

[tex]\frac{p}{2} =175[/tex]

[tex]p=350[/tex]

The answer I get from the equation would be $350.

If you input 350 into it:

[tex]\frac{(350)}{2} -25[/tex]

[tex]175 -25[/tex]

[tex]150[/tex]

Answer:

P = 150 ÷ 2 - 25 = p

Step-by-step explanation:

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.

Given: Harry bought a broken motor scooter, fixed it, and sold the scooter for $150. $25 less than 2 times the amount he paid for it.

To find: Which equation can be used to find, p, the amount of money Harry originally paid for the scooter?

Solution: It says; "That was $25 less than 2 times the amount he paid for it"

With that said, find the amount that is 2 times more than 150. To find that, the opposite of times is division, so divide 150 by 2

[tex]150[/tex] ÷ [tex]2 =[/tex] [tex]75[/tex]

Now that has been found, the next thing to find is $25 less, less means subtract. To calculate the amount Harry originally paid for the scooter, subtract 25 from 75

[tex]75 - 25 = 50[/tex]

Therefore, the amount of money Harry originally paid for the scooter is $50

Hence, the equation can now be found as; P = 150 ÷ 2 - 25 = p

Answer:

Slope = -⁵/3

Step-by-step explanation:

See the attachment below. In the attachment, the green line represents the the rise while the red line represents the run of the line.

The slope = rise/run

Rise = 5

Run = 3

Slope = -(5/3)

Slope = -⁵/3 (the slope would be negative because the line slants downwards from your left to the right)

Answer:

the first step is to divide two by three x

Answer:

x = 12

Step-by-step explanation:

Eliminating the fractional coefficient would be a great start:

8 = (2/3)x becomes 24 = 2x after multiplication of both sides by 3.

Then x = 12

Answer:

1- 9.5kg

2- 19kg

5- 47.5kg

Step-by-step explanation:

1+2+5= 8

76÷8= 9.5

9.5 ×1= 9.5

9.5× 2= 19

9.5× 5= 47.5

Answer:

80%

Step-by-step explanation:

[tex]\frac{3600}{4500}= \frac{y}{100}[/tex]

4500 × y = 100 × 3600

4500y = 360000

4500y ÷ 4500 = 360000 ÷ 4500

y = 80

Answer:

Interest rate ≈ 3.48%

Step-by-step explanation:

The rate of interest is 0.87 percent.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal= $640, time= 20 years and amount =$1280.

The interest is compounded quarterly.

Here, 1280=640(1+r/100)⁸⁰

1280/640 = (1+r/100)⁸⁰

2 = (1+r/100)⁸⁰

1.0087 = 1+r/100

0.0087=r/100

r=0.0087×100

r=0.87%

Therefore, the rate of interest is 0.87 percent.

Answer:

Hm, if Ariana wants to save money for her house, she should spend less money on fast food a month because if she spending $100 dollars for takeout coffee and spending at the same time a month for fast food. she should eat less fast food and less money for coffee because she would be spending way too much money because F = $200 and C = $100 dollars, so $200 + $100 dollars would be $300 dollars a month. she could still have takeout coffee however, not every month. The fast food needs to be taken out of her diet as well because its the fact its unhealthy and costing her way too much money, she should stop having fast food and not have coffee or the fast food EVERY MONTH, she could have the fast food evert 5 months and her takeout coffee every once a month. hopefully this helps ^^

Answer:

The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].

Step-by-step explanation:

The coordinates of the point P' is determined by the following expression:

[tex]P'(x, y) = P(x,y) + T(x,y)[/tex] (1)

Where:

[tex]P(x,y)[/tex] - Original point.

[tex]P'(x,y)[/tex] - Translated point.

[tex]T(x,y)[/tex] - Translation vector.

If we know that [tex]P(x,y) = (3, -3)[/tex] and [tex]T(x,y) = (-2, 3)[/tex], then the coordinates of point P':

[tex]P'(x,y) = (3, -3) + (-2, 3)[/tex]

[tex]P'(x,y) = (1, 0)[/tex]

The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].

Point B is tangent to the circle so the angle ABC would be 90 degrees.

Answer:

[tex] \frac{x + 2}{ {x}^{2} - x - 20 } [/tex]

Step-by-step explanation:

Since the roots are -4 and 5, we can write that as

[tex](x + 4)(x - 5)[/tex]

Apply foil method to find our denominator.

We get

[tex] {x}^{2} - x - 20[/tex]

So that our denominator.

Since our denomiater gives us interger asymptote, our degree in our numerator must be 1 so the answer has to be a single interger or a single term.

Since our x intercepts is -2, we use

[tex](x + 2)[/tex]

So our rational denomiater is

[tex] \frac{x + 2}{ {x}^{2} - x - 20 } [/tex]

Answer:

1. b = kt²

2. Y = k / 3√r

3. r = ktu

4. m = kn² / p

Step-by-step explanation:

1. b varies directly with the square of t

b = k * t²

b = kt²

2. Y is inversely proportional to the cubre root of r

Y = k / 3√r

3. r varies jointly as t and u

r = k * t * u

r = ktu

4. m varies directly as the square of n and inversely to p

m = (k * n²) / p

m = kn² / p

1. b = kt²

2. Y = k / 3√r

3. r = ktu

4. m = kn² / p
