10 times the product of g and h

Answers

Answer:

10(g*h)

Step-by-step explanation:

the * is supposed to mean times/multiply

since it is an expression you do not put y= or f(x)= or anything like that

Answer:

10(g*h)

Step-by-step explanation:

"Product" means multiply so you would want to multiply g and h together. You put it in parenthesis because you want to multiply the solution you get from multiplying g and h by 10. To show this, you can simply just put the 10 in front of  the parenthesis as that implies multiplication.

The art supply store is having a sale. Paint sets are 20% off and everything else is 15% off. Before the discount, a paint set is priced at $43.50, a canvas is $12.75, and paint brushes are $7.50. Mary purchases all three of these items. About how much did Mary spend after the discount, before sales tax? Group of answer choices

Answers

Answer:

Step-by-step explanation:

Step one:

given

paint set= $43.50

20% off 43.50

20/100*43.50

0.2*43.50

=$8.7

43.5-8.7

new price of paint set=$34.8

canvas=$12.75

15% off 12.75

15/100*12.75

0.15*12.75

=1.9125

=12.75-1.9125

new price of canvas=$10.83

paint brushes are $7.50

15% off $7.5

15/100*7.5

0.15*7.5

=1.125

=7.5-1.125

new price of paint brush=$6.38

total =$34.8+$10.83+$6.38= $39.25

Answer:

actually the answer is 52

Step-by-step explanation:

20% x 43.50/100 = 34.8

12.75 x 15% /100 = 10.83

7.50x 15%/100 = 6.37$

Add all of them together and you will get 52$

Easiest way to do it

20% x 43.50/100

12.75 + 7.50 = 20.25

20.25 x 15%/ 100 = 3.03

20.25 - 3.03 = 17.21

Then add all of them together and you will still end up with about 52$

17.21 + 34.8 = 52

how do you graph x - y < 4

Answers

Answer: y > -4 + x

Step-by-step explanation: graph the inequality by finding the boundary line

Answer:

y > -4 + x

***(see graph below)****

Step-by-step explanation:

Graph

x − y < 4

Solve for y

Subtract x from both sides of the inequality.

−y < 4 − x

Multiply each term in −y < 4 − x by −1

Multiply each term in −y < 4 − x by −1. When multiplying or dividing both sides of an

  inequality by a negative value, f lip the direction of the inequality sign.

  (−y) ⋅ −1 > 4 ⋅ −1 + (−x) ⋅ −1

     Multiply (−y) ⋅ −1.

     Multiply −1 by −1.

     1y > 4 ⋅ −1 + (−x) ⋅ −1

     Multiply y by 1.

     y > 4 ⋅ −1 + (−x) ⋅ −1

Simplify each term.

     Multiply 4 by −1.

      y > −4 + (−x) ⋅ −1

     Multiply (−x) ⋅ −1.

y > −4 + x

   Find the slope and the y-intercept for the boundary line.

Rewrite in s lope-intercept form.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Reorder −4 and x. y > x − 4

Use the slope-intercept form to find the slope and y-intercept.

Find the values of m and b using the form y = mx + b. m = 1

b = −4

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 1

intercept: (0, −4)

Graph a dashed line, then shade the area above the boundary line since y is greater than −4 + x. y > −4 + x

A candle has been burning for 20 min and is now 25 cm tall. In an hour it will be 10 cm tall. Which equation models the height y of the candle in centimeters, x minutes after it was lit?

Answers

Answer:

(y - 25) = - 0.25(x - 20)

Step-by-step explanation:

Given that :

Height of candle after burning for 20 minutes = 25 cm

Height after burning for 1 hr (60 minutes) = 10 cm

Height (y) in cm of candle x minutes after being lit:

Using the equation :

(y - y1) = m(x - x1)

m = (change in y / change in x)

Change in height within 60 minutes :

Height at 20 minutes = 25cm

Height after an hour = 10

Change in height per hour = (25 - 10) = 15cm

Hence, m = change in height per minute

15cm / 60 = 0.25cm ( - 0.25) (decrease in height)

y1 = 25 ; x1 = 20

(y - y1) = m(x - x1)

(y - 25) = - 0.25(x - 20)

Answers

Total number of carriers to deliver the newspapers = 18

Each newspaper carrier delivers the same number of newspapers.

To find:

The number of newspapers that each newspaper carrier will deliver ?

Solution:

The solution to this problem lies in the language of the problem itself.

As we are given that every newspaper carrier will deliver the same number of newspapers.

Therefore, we need to divide the total number of newspapers i.e. 4050 in 18 (number of newspaper carriers) equal parts.

So, the answer is:

A park in the shape of a rectangle is 18 miles long and 24 miles wide. How much shorter is your walk
if you walk diagonally across the park instead of along the two sides of it?

Answers

Answer:

18² + 24² = x²

900 = x²

x = 30

18 + 24 = 42

42 - 30 = 12

Its shorter for 12 miles

Answer:

12 miles less

Step-by-step explanation:

18+24=42

If you walk in a L shape you walk 42 miles

If you walk diagonally:

ABC Right triangle

We have A and B (18 and 24)

Using the pythagorum theorem

a^2+b^2=c^2

18^2+24^2=C^2

324+576=C^2

900=C^2

Square root of 900=C

30=C

You would walk 30 miles

42-30=12

By walking diagonally, you would walk 12 miles less than going all the way around.

Complete question :

On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.

Answer:

1.497 * 10^8km

149700000 km

Step-by-step explanation:

Given that:

Time taken = 8 minutes 19 seconds

Speed of light = 3 * 10^8 m/s

Distance from earth to sun :

Speed * time

(3 * 10^8) * ((8 * 60) + 19)

(3 * 10^8) * 499

= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km

= 149700000000 m

= 149700000 km

= 1497

Leroi and Sylvia both put $300 in a savings account. Leroi decides he will put in an additional $60 each week. Sylvia decides to put in an additional 20% of the amount in the account each week. Complete the sentence to answer the question.

Answers

Answer: See explanation

Step-by-step explanation:

Here is the remainder of the question:

a. Who has more money after the first additional deposit? Explain.

b. Who has more money after the second additional deposit?

a. Amount put in savings account = $300

Leroi's amount after first week = $300 + $60 = $360

Sylvia's amount after first week = $300 + (20% × $300) = $300 + (0.2 × $300) = $300 + $60 = $360

They both have equal amount after the first week.

b. After the second deposit,

Leroi's saving = $360 + $60 = $420

Sylvia's saving = $360 + (20% × $360) = $360 + $72 = $432

Sylvia has more savings after the second week
