Hey store buys a jacket for $20 then sells it to customers for 80% more than what is the selling price of the jacket

Answers

Given:

Cost of a jacket = $20

Then sells it to customers for 80% more than.

To find:

The selling price of the jacket

Solution:

We have,

Cost of a jacket = $20

Selling price = cost + 80% of cost

                     = [tex]20+\dfrac{80}{100}\times 20[/tex]

                     = [tex]20+\dfrac{8}{1}\times 2[/tex]

                     = [tex]20+16[/tex]

                     = [tex]36[/tex]

Therefore, the selling price of the jacket is $20.

Write an exponential function in the form y=ab^x that goes through points (0, 18)and (3, 6174)

Answers

Answer:

[tex]y = 18 \times {7}^{x} [/tex]

Step-by-step explanation:

Using the formula for exponential function,

[tex]y = ab {}^{x} [/tex]

Let plug in 0,18.

[tex]18 = ab {}^{0} [/tex]

Using the zero power rule,

[tex]b {}^{0} = 1[/tex]

[tex]18 = a \times 1[/tex]

[tex]a = 18[/tex]

Since a equal 18 let plug in what we know so far

[tex]y = {18b}^{x} [/tex]

Now let find b.

Let use the other point, 3,6174

[tex]6174 = {18b}^{3} [/tex]

Divide 18 by both sides and we get

[tex]343 = b {}^{3} [/tex]

Take the 3rd root of 343

[tex] \sqrt[3]{343} = b = 7[/tex]

b=7

The equation is

[tex]y = 18 \times 7 {}^{x} [/tex]

Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $2.40 plus $4.50 per mile. The total fare was $87.90, not including the tip. Write and solve an equation which can be used to determine mm, the number of miles in the taxi ride.

Answers

Answer:

The taxi drove Hailey for 19 miles.

Step-by-step explanation:

1. Subtract the tip.

$87.90 - $2.40 = $85.5

2. Divide by the price per mile. ($4.50)

$85.5 / $4.50 = 19

3 A small photograph has a width of 4 cm and a length of 6 cm
Dean enlarges the small photograph
The enlarged photograph has a length of 21 cm
Work out the width of the enlarged photograph

Answers

Answer:

14 cm

Step-by-step explanation:

Given that the width is 4 cm and the length is 6cm. If after enlargement, the length becomes 21 cm, the multiplier or factor of enlargement x may be computed as

6 * x = 21

Divide both sides by 6

x = 21/6

= 7/2 = 3.5

Hence increasing the width by the same factor, the width of the enlarged photograph will be

= 3.5 * 4 cm

= 14 cm

what 2 numbers multiply to -63 and add to-2​

Answers

7*-9
=-63 and 7+-9 adds to -2

Two numbers are 7 and -9, so their product is -63 and sum is -2.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Let two numbers are x and y

Given,

The multiplication of 2 numbers is -63

[tex]x\times y =-63[/tex]

The addition of 2 numbers is -2

[tex]x+y =-2[/tex]

[tex]x=-2-y[/tex]

On substituting x in [tex]x\times y =-63[/tex]

[tex](-2-y)y=-63[/tex]

[tex]-2y-y^2=-63[/tex]

[tex]y^{2} +2y-63=0[/tex]

[tex](y-7)(y+9)=0[/tex]

[tex]y=7\\y=-9[/tex]

[tex]x=-2-y\\[/tex]

At y=7

x=-9

At x=-9

y=7

Thus, two numbers are 7 and -9
