She bought 11 books because her original total was 66$ minus the 8$ discount would be the 58 so u take the 6 and 66 and find the multiple of it witch is 11 I believe so.

Answer:

10,000 square meters.

Step-by-step explanation:

First, let's split this shape into a rectangle and a triangle to make it easier.

<em>Rectangle:</em>

A = bh

We know the base is 120m and the height is 30m. So simply plug those into the equation.

A = (120)(30) = <em>3,600 square meters.</em>

<em>Triangle:</em>

A = 1/2bh

Since we split the shape up, we have to calculate the triangles base and height.

To find the base, take the 120 and subtract the 40, giving us 80.

To find the height, take the 190 and subtract the 30, giving us 160.

Now take those numbers and plug them into the equation.

A = 1/2(80)(160) = 1/2(12,800) = <em>6,400 square meters.</em>

<em>Total:</em>

Simply add the area of the rectangle to the area of the triangle to find the area of the entire shape.

A = 3,600 + 6,400 = 10,000 square meters.

Pls answer this is due in 30 minutes
ziro4ka [17]

Answer:

1a) t = 0.17b

1b) $36.03

2) 51,167.50

Step-by-step explanation:

1a) 17% converted to a decimal (divide by 100) = 0.17. Multiply that by the amount of the bill (before tipping) to get the amount of the tip

1b) The bill of $248 represents the entire bill (100%) plus the tip amount (17%) which makes 117%. As a decimal, this is 1.17.

To find what the cost was without the tip, divide the bill total by 1.17

248/1.17 = 211.97. That was the bill before the tip was added.

248-211.97 = 36.03 was the tip added.

2) 5.5% converted to a decimal is 0.055

0.55 x 48,500 = 2667.50

$2,667.50 + $48,500 = 51,167.50

Or, you can use what we did in 1b, and his new salary is 1.055 times 48,500

1.055 x 48,500 = 51,167.50

He measure of one angle of an octagon is twice that of the other seven angles. what is the measure of each angle? answer: ,
Scrat [10]
Answer:
measure of larger angle = 240 degrees
measure of each of the smaller angles = 120 degrees

Explanation:
In any polygon, the sum of measures of interior angles can be calculated using the following rule:
sum of interior angles = (n-2)*180 where n is the number of sides

Now, for an octagon, n=8, this means that:
sum of measures of interior angles = (8-2)*180 = 1080°

An octagon has 8 interior angles, one of which is twice the measure of the others.
Assume that each of the 7 smaller angles is x degrees and that the larger angle is 2x degrees

Computing their summation, we will find that:
x + x + x + x + x + x + x + 2x = 1080
9x = 1080
x = 120

This means that:
each one of the smaller angles = x = 120 degrees
the larger angle = 2x = 2 * 120 = 240 degrees

Hope this helps :)

lianna [129]

Answer:

If you have a group of 700 men, 56 will be color blind

Step-by-step explanation:

The theoretical probability that a man will have some form of color blindness is 8%.

Number of men in group = 700

Number of men with color blindness in a group of 700 men  

If you have a group of 700 men, 56 will be color blind

Croscheck 8% of 700 is 56
