B - 45 because 27 divided by 6 is 4.5 and then 10x4.5=44

yaroslaw [1]
You have a bunch of interesting figures there (check the diagram):
- square (in red)
- parallelogram (in green)
- Isosceles trapezoid (in yellow)
- Isosceles triangles (blue, and purple)
Notice that you have more than one of the same figures: a bunch of small isosceles triangles, tow isosceles trapezoids, two big isosceles triangles... etc.

I don’t understand how to solve it
kykrilka [37]

Answer:

x= $878.85

Step-by-step explanation:

1349.99=1350

1350=100%     you cross multiply and then divide by 100 you get x = 540

  x   =40%

504 is how much can be off the original price, 1350-504=810

You would pay 810 dollars if the coupon was 40% off. Now we gotta find how much is the tax rate.  

810=100%    do the cross multiply and then divide by a 100, you get x=68.85

x   =8.5

 Then you have to add your tax rate to the price that you are paying, 810+68.85=$878.85.

Hope this helps you!

A well is to be dug at the location in the diagram. Use the diagram for the parts.
Juliette [100K]

Answer:

y = \frac{1}{6}x - 5

Step-by-step explanation:

The equation that represents the road can be written as y = mx + b

Find, m = slope, and b = y-intercept of the line.

Using two points on the line, (-6, -6) and (6, -4), find the slope:

slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-6)}{6 -(-6)} = \frac{2}{12} = \frac{1}{6}

Substitute x = -6, y = -6, and m = ⅙ into y = mx + b to find b.

-6 = \frac{1}{6}(-6) + b

-6 = -1 + b

Add 1 to both sides

-6 + 1 = b

-5 = b

Substitute m = ⅙, and b = -5 into y = mx + b.

✅The equation that represents the road would be:

y = \frac{1}{6}x + (-5)

y = \frac{1}{6}x - 5

The function y=-0.25+1 represents the percent y (in decimal form)  A battery power remaining x hours after you turn on the lap
Dmitry [639]

Answer:

The slope is -0.25. This means that the power reduces by 0.25 percent per hour

Step-by-step explanation:

Given

y = -0.25x + 1

Required

Identify and interpret the slope

An equation has a general form:

y = mx + b

Where

m = slope

Compare y = mx + b to y = -0.25x + 1

We have:

mx = -0.25x

Divide both sides by x

\frac{mx}{x} = \frac{-0.25x}{x}

m = \frac{-0.25x}{x}

m = -0.25

Because the result of the above calculation is negative, it means that the function reduces

<em>The given function measures the percentage of power by hour.</em>

<em>So, the power reduces by 0.25% per hour</em>
