A shirt is advertised for 30% off the list price of $19.00. What is the sale price?

The sale price is $ ????????????

Answers

Answer:

13 dollars

Step-by-step explanation

30 percent - 0.3

0.3 times 19 = 13

Answer:

$13.30

Step-by-step explanation:

This problem is asking you to find thirty percent of nineteen. So, after setting up the proportion and doing the cross multiplying, I found that the amount of the discount is five dollars and seventy cents.

Now that I have the discount price, I just needed to subtract that from the regular price. Nineteen dollars minus five dollars and seventy cents is thirteen dollars and thirty cents. The cost of the shirt on sale is thirteen dollars and thirty cents.

What is 30% of 19? ?/ 19 = 30/100 19 x 30 = 570 ÷100= 5.7. The discount is $5.70 $19.00-$5.70= $13.30. so the sale price is $13.30

A circular clock has a circumference of 48.5 meters. What the measurement of the radius, in meters, of the clock?

Answers

Answer:

The radius of the clock is 7.72 meters

Step-by-step explanation:

Here, we want to calculate the radius of a clock which has a circumference of 48.5 m

Mathematically;

Circumference C = 2 * pi * r

48.5 = 2 * 22/7 * r

7 * 48.5 = 44r

r = (7 * 48.5)/44

r = 7.72 meters

A toy maker wants to re-create the Wright Brothers 1903 airplane. The actual plane was 21 feet long. The toy maker wants to use a scale model of 3 feet = 2 inches. How long will the replica plane be?

Answers

Answer:

[tex]x = 14ft[/tex]

Step-by-step explanation:

Given

[tex]Actual\ Length = 21ft[/tex]

Model:

[tex]3\ ft = 2\ in[/tex]

Required

Determine the length of the replica

Represent the model as a ratio:

[tex]Ratio = 3\ in:2\ ft[/tex]

Convert to fraction

[tex]Ratio = \frac{3\ in}{2\ ft}[/tex]

Represent the actual lengths as a ratio

[tex]Ratio = 21\ ft : x[/tex]

Where x is the length of the replica

Convert to fraction

[tex]Ratio = \frac{21\ in}{x}[/tex]

Equate both ratios (because they are in proportion)

[tex]\frac{3\ in}{2\ ft} = \frac{21\ in}{x}[/tex]

[tex]\frac{3}{2\ ft} = \frac{21}{x}[/tex]

Cross Multiply:

[tex]3 * x = 21 * 2\ ft[/tex]

[tex]3x = 42\ ft[/tex]

Solve for x

[tex]x = \frac{42ft}{3}[/tex]

[tex]x = 14ft[/tex]

Hence, the length of the replica is 14ft

[tex]x^2+8x+11=0[/tex]

Answers

Answer:

x > 2

y ≥ 2

x + y ≤ 8

Step-by-step explanation:

Here, we want to write a system of equations according to the given variables

More than means, greater than

since x is the variable we want to use;

x > 2

At least 2 hours means greater than or equal to 2

That is mathematically represented as;

y ≥ 2

At most means less than or equal to

So;

x + y ≤ 8
