Answer:

B

Step-by-step explanation:

(15^3)^3 because the exponent outside of the parentheses multiplies both the 15 and the exponent inside the parentheses, so it's not 15^6, its 15^2 ^6

Answer:

18/56

Step-by-step explanation:

9/28= 18/56

for the top 1 I multiplied the numerator and denominator by 2 and then when you simplify it you get 9/28

Answer:

0.3

Step-by-step explanation:

First you need to add 1/4 and 9/20, and you would get 7/10. That only leaves 3/10, which as a decimal is 0.3.

The decimal that represents the amount of a human bone that is living tissue is 0.3

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that human bone is made up of water 1/4 and 9/20 minerals, and the rest is living tissue.

First we need to add 1/4 and 9/20,

Thus we would get 7/10.

That only leaves 3/10, which as a decimal is 0.3.

The decimal that represents the amount of a human bone that is living tissue is 0.3

Answer:

4y^2 - 10y + 23

Step-by-step explanation:

Answer:

Step-by-step explanation:

(22 - 7y + 6) - (-4y² + 3y + 5) = 22 + -7y + 6 + 4y² - 3y  - 5

                                             = 22 + 6 - 5 - 7y - 3y  + 4y²

                                            = 23 - 10y + 4y²

Answer:

n=5

Step-by-step explanation:

take 29 add to 56 then divided by 17

Answer:

5

Step-by-step explanation:

56 = 17n - 29

-17n = -29 - 56  [remember: when u transfer a positive number it becomes negative and when u transfer a negative number it becomes positive]

-17n = -85

n = -85/-17

n = 5

Answer:

y=4x+3

Step-by-step explanation:

The slope is positive 4 and the y intercept is 3

Answer:

y = 4x + 3

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept

The slope is how much units it goes up/down while how much units it goes left/right from one point to the other. So two points we'll use for reference is (-1, -1) and (0, 3). You want to make sure the points u choose are whole numbers cause they're easier to tell. So the distance between those 2 points if it goes to the right once and goes up 4 units. Left/right is x and up/down is y, y/x is how u write the slope. So it's 4/1 which is just 4

The y-intercept is just where the line intercepts on the y-axis. The line goes through the point 3 on the y-axis, so it's 3

Input the numbers in the equation and it's y = 4x + 3

Answer: slope is -10, y intercept is + 2

Step-by-step explanation:

slope is -10, y intercept is + 2

Complete question :

Lilian purchased a violin form smash music stores. It regularly sold for $670, but wa son slaw for 10% off. She also had to pay 8% sales tax. She bought it on the installment plan and paid 15% of the total cost with tax as a down payment. Her payments were $58 per month for one year. What is her sales tax?

Answer:

$48.24

Step-by-step explanation:

Given that:

Sales price = 670

Discount = 10% off

Sales tax = 8%

Discounted price = (1 - 0.1) * 670

Discounted price = 0.9 * 670 = $603

Hence, purchase price = $603

Hence, sales tax = 8% of purchase price

8% of $603

0.08 * 603 = $48.24

Answer:

12%

Step-by-step explanation:

So 5.5 to 5.62 is .12

Then calculate the difference of 5.5 *.12=0.66

Then do “0.66 is what percent of 5.5?”

The answer is 12%

Answer:

[tex]y = \frac{3}{5} + x[/tex]

Step-by-step explanation:

Given

Represent Mai's distance as x and Clare's distance as y

[tex]Mai = x\ miles[/tex]

[tex]C = \frac{3}{5}[/tex] farther than Mai

Required

Determine the relationship between both

[tex]C = \frac{3}{5}[/tex] farther than Mai

Substitute x for Mai

[tex]C = \frac{3}{5}[/tex] farther than x

Express as a mathematical expression:

[tex]C = \frac{3}{5} + x[/tex]

Recall that Clare's distance is represented by y.

So, we have:

[tex]y = \frac{3}{5} + x[/tex]

Hence, the relationship is: [tex]y = \frac{3}{5} + x[/tex]

Answer: Mai skated x miles, and Clare skated 3/5 farther than that. Write an equation to represent the relationship between the distance Mai skated (x) and the distance Clare skated (y).
