Answer:

$78,000

Step-by-step explanation:

Because their are 52 weeks in a year and 52 X 1500 is $78,000

Answer:

Since there are 52.14 Weeks in a year you would multiply how many weeks there are in a year and how much Mr.white gets paid weekly and you get $78,210 in year.

Step-by-step explanation:

Answer:

A pair of Nike Air Jordan sneakers cost $139.99.

There is a 35% off sale going on at Foot Locker.

=> Sale price = 139.99 - 139.99 x 35/100 = ~$90.99

Sales tax is 8.125% in Orange County.

=> The tax = 90.99 x 8.125/100 = ~$7.39

The total price is calculated by:

P = The sale price + The tax = 90.99 + 7.39 = ~$98.38

Hope this helps!

:)

Answer: Sale price before tax $90.99

Tax $7.39

Total after tax $98.38

Step-by-step explanation:

Sale price 139.99 x 0.65 = 90.99

Tax 90.99 x 8.125/100 = 7.39

Total 90.99 + 7.39 = 98.38

Answer:

(g°f)(4) = -1296

Step-by-step explanation:

It is given that:

g(x) = -6x² - 86x - 8

f(x) = 4x - 2

First find the equation of (g°f)

(g°f) = g [ f (x) ]

(g°f) = g [ 4x-2 ]

Substitute 4x-2 for x in formula of g(x)

g(x) = -6x² - 86x - 8

g(4x-2) = -6(4x - 2)² -8(4x - 2) - 8

g(4x-2) = -6(16x² + 4 - 2(4x)(2)) - 32x + 16 - 8

g(4x-2) = -96x² - 24 +96x - 32x + 16 - 8

g(4x-2) =  -96x² + 64x - 16

(g°f)(x) =  -96x² + 64x - 16

Substitute x=4 into the equation:

(g°f)(4) =  -96(4)² + 64(4) - 16

(g°f)(4) = -1296

Answer:

B) They will have the same amount in week 4.

Step-by-step explanation:

Jose:  y = -25x +250

Martin: y = 30x + 30

Plug in 6

Jose: y = -25(6) + 250    y = 100

Martin: y = 30(6) +30      y = 2100

Plug in 4

Jose: y = -25(4) + 250      y = 150

Martin: y = 30(4) + 30         y = 150

Answer:

One solution

Step-by-step explanation:

-t+5=7

-t=2

t=-2

Answer:

One solution: t = -2.

Step-by-step explanation:

To figure out how many solutions an equation has, it would be best to compute the solution first.

Given:

3t + 5 = 4t + 7 // Subtract 3t from both sides.

5 = t + 7 // Subtract 7 from both sides.

t = -2.

Answer:

[tex]x=4/55\\y=-69/55[/tex]

Step-by-step explanation:

[tex]\frac{55}{4} y=\frac{-69}{4}[/tex]

[tex]y=\frac{-69}{55}[/tex]

[tex]x=\frac{-9(-69/55)-11}{4}\\x=\frac{4}{55}[/tex]

Answer:

(- 4, - 3 )

Step-by-step explanation:

Given the 2 equations

- 4x + 9y = - 11 → (1)

- 3x + 7y = - 9 → (2)

Multiplying (1) by 3 and (2) by - 4 and adding will eliminate the term in x

- 12x + 27y = - 33 → (3)

12x - 28y = 36 → (4)

Add (3) and (4) term by term to eliminate x

- y = 3 ( multiply both sides by - 1 )

y = - 3

Substitute y = - 3 into either of the 2 equations and evaluate for x

Substituting into (1)

- 4x + 9(- 3) = - 11

- 4x - 27 = - 11 ( add 27 to both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4

Solution is (- 4, - 3 )

Answer:

D.) 68 units²

Step-by-step explanation:

The formula for the area of a triangle is:

A = bh/2

where b is the base and h is the height

Substitute the given values into this formula:

A = bh/2

A = (17)(8)/2

Solve:

A = (17)(8)/2

A = 136/2

A = 68

Therefore, the area is 68 square units.

Answer:

Step-by-step explanation:

When we plan an effective budget, we certainly need to gather some data about the theme, which includes, prices, description of the stuff we need. Once we have the data we need, then we must organize it to set priorities, to make the budget effective.

Additionally, estiamting and finding averages are important skills, because we need to estimate how effective is the budget. In fact, maybe we would desing different budgets to compare them and analyse, using averages, which one is the most effective.

Answer:

35/80

u want to find a number that is proportional to 35/80, then all u need is a number that is equivalent...another words, if it is proportional, it is an equivalent fraction to 35/80.

there can be several answers to this...such as 35/80 reduces to 7/16...so 7/16 is proportional....or if u multiply numerator and denominator by the same number, u will find a proportional number...

example :

35/80 * 2/2 = 70/160...this is proportional

35/80 * 3/3 = 105/240...this is proportional

35/80 * 4/4 = 140/320...this is also proportional

and so on....

so without giving us any answer choices, there can be many numbers to choose from

Answer:

hello

Thanh have 3,5 meters of fabric. i can say

3,5/1 for it.

and i can say 35/10

now he used three-fourths of a meter of fabric.

its equal to 3/4

now i have to remove 3/4 from 35/10.

35/10 - 3/4

denominators have to be same thats why im expanding them to 20.

35×2/10×2 = 70/20

3×5/4×5 = 15/20

now i can remove 15/20 from 70/20!

70/20 - 15/20 = 55/20

we cannot see 55/20 in the options.

thats why im dividing them with 5.

55÷5= 11 20÷5=4

the answer is 11/4

11/4 = 2and 3/4

so its option 2

good luck(:
