Answer:

15,840 i did this in test and got 100%

Step-by-step explanation:

The total feet ran by Rachel is given by the equation A = 15,840 feet

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the total miles ran by Rachel be A = 3 miles

Now , the value of 1 mile = 5,280 feet

Substituting the values in the equation , we get

The distance of 3 miles in feet = 3 x value of 1 mile

On simplifying the equation , we get

The distance of 3 miles in feet = 3 x 5,280

The distance of 3 miles in feet = 15,840 feet

Therefore , the distance ran by Rachel A = 15,840 feet

Hence , the equation is A = 15,840 feet

Marcus will receive $5,193.82 when he redeems the CD at the end of the ​11 years.

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

A=P(1+r/n[tex])^{nt}[/tex]

Where:

A = the future value of the investment or loan

P = the principal investment or loan amount

r = the interest rate (decimal)

n = the number of compound periods

Marcus receives an inheritance of ​$3,000.

He decides to invest this money in an 11 ​-year certificate of deposit​ (CD) that pays 5.0 ​% interest compounded monthly.

P = $3,000

r =5%

t = 11 years

A=P(1+r/n[tex])^{nt}[/tex]

Substitute the values of P, r and t in the formula,

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A=P(1+r/n[tex])^{nt}[/tex]

A = 3,000.00(1 + 0.05/12[tex])^{(12)(11)}[/tex]

A = 3,000.00(1 + 0.0041666666666667[tex])^{132}[/tex]

A = $5,193.82

Therefore, Marcus will receive $5,193.82.

Answer:

C. since 8, 15, 17 are pythagorean triples

Answer:

$3240

Step-by-step explanation:

First you need to find the area of that lot. Area of a rectangle = length x width. But you also have mixed units...yards and feet. Since the price of the sod is in square yards, we'll convert the 45 feet to yards. 3 feet = 1 yard, so divide 45 by 3, = 15 yards.

18 x 15 = 270 square yards

then you multiply that by the $12/square yard

270 x 12 = $3,240

Please lmk if you have questions

Answer:

270$

Step-by-step explanation:

Step-by-step explanation:

Formula for simple interest:

[tex]a = p(1 + rt)[/tex]

where

a = final amount

p = principal amount

r = interest rate per annum

t = time in years

Now, we are finding a, the final amount, and given,

p = $650

r = 5.5% (5.5/100)

t = 4 years

[tex]a = 650(1 + (\frac{5.5}{100} )(4)) \\ = 650(1 + (0.055)(4)) \\ = 650(1 + 0.22) \\ = 650(1.22) \\ = 793 \: dollars[/tex]

Answer:

C.$793

Step-by-step explanation:

were looking to 5.5% of 650 but in order to do that first we need to find 1%, we can do that by dividing by 100

650=100%

/100  /100

6.5=1%

now we can multiply by 5.5 to get 5.5%

6.5 = 1%

x5.5 x5.5

35.75=5.5%

now we are looking to find how much money is in the account total after 4 years

so the equation is

(35.75x4)+650

143+650

$793 in total

Step-by-step explanation:

15 multiplied by 20% is 3

Subtract 3 from 15 and you get 12

Answer:

yes , see explanation

Step-by-step explanation:

We require 2 equations with the recurring 3 placed after the decimal point.

let x = 0.7333..  ( multiply both sides by 10 and 100 )

10x = 7.333... → (1)

100x = 73.333.... → (2)

Subtract (1) from (2) , eliminating the recurring 3

90x = 66 ( divide both sides by 90 )

x = [tex]\frac{66}{90}[/tex] = [tex]\frac{11}{15}[/tex]

The angles of a triangle should sum up to 180.

But the is 191°

Answer:

C

Step-by-step explanation:

Answer:

m<D = 52°

Step-by-step explanation:

x + 20 + 3x + 32 = 180

4x = 128

x = 32

m<D = x + 20 = 32 + 20 = 52°

Answer:

c. (1/2, 8)

Step-by-step explanation:

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.

-2x + y = 7

Step 1: Subtract y from both sides of the equation.

-2x = -y + 7

Step 2: Divide both sides by -2

x = 1/2y - 7/2

Substitute what you see above this statement for y in the other equation.

6(1/2y - 7/2) + y = 11

Step 3: Multiply 6 by 1/2y - 7/2.

3y - 21 + y = 11

Step 4: Combine y and 3y.

4y - 21 = 11

Step 5: Add 21 to both sides

4y = 11 + 21

4y = 32

Step 6: Divide both sides by 4.

y = 32/4

y = 8

Step 7: Substitute 8 for y in x = 1/2y - 7/2 Because the resulting equation contains only one variable, you can solve for x directly.

x = 1/2(8) - 7/2

Step 8: Multiply 1/2 by 8.

x = 4 - 7/2

Step 9: Add -7/2 to 4.

x = 1/2

The system is now solved, and we get C (1/2, 8) as our answer.

Answer:

The maximum height of the projectile is 90 ft

Step-by-step explanation:

Here, we want to get the maximum height reached by the projectile

The answer here will be the y-coordinate value of the vertex form of the given equation

so firstly, we have to write the equation in the vertex form

We have this as;

y = -16t^2 + 64t + 26

That will be;

y = a(x-h)^2 + k

y = -16(x-2)^2 + 90

where the vertex of the equation is;

(-h,k)

K

in this case is 90 and thus, that is the maximum height of the projectile

Answer:

that is b
