Answer:

So, he starts out with $15. Then, Monday - Friday he spends 1.50 every day. (Except Friday.) So then you do 4 days x 1.50 (5 x 1.50 = 6) and that equals 6. Then on Friday, he buys 4 pieces of pizza, and a piece of pizza equals $1.40. So then you do 4 x 1.40, and that equals 5.6. (4 x 1.40 = 5.6) Now you add up 5.6 and 6, and you get 11.6. (5.6 + 6 = 11.6) Then you subtract 11.6 from 15 and you get 3.4! (15 - 11.6 = 3.4)

So, after the week, he has $3.4, so spend on whatever else.

Answer: zoe's question's data would vary because not everyone in her class could play video games for the exact same amount of time.

however this is not a statistical question because we do not know when the students are playing video game for example we wouldnt know if she wanted to know how much time a classmates spends playing video games each year, each month, each week, etc. so to make this a statistical question zoe would have to ask....  which student spends the most time a day on video games.

hope this helps ;D

Answer:

C. 56°

Step-by-step explanation:

The measures of a triangle all add up to 180. Since this is a right triangle, we already know one of the measures is 90 degrees. Another measure is given to us, and we need to find measure Q. So far:

mQ = ?

mR = 34°

mS = 90°

To find the remaining angle, just subtract what you already have from the total

180 - (90 + 34) = ?

180 - 124 = 56

Step-by-step explanation:

1. Add -8 to both sides, which gives you [tex]8x\leq -64[/tex], as -72 +8 = -64

2. Then, divide 8 from both sides, which gives you [tex]x\leq -8[/tex].

Scale factor: 1/2

Step-by-step explanation:

Think of it as division.

From side B to C it is 3 units.

From side B' to C' it is 1.5 units.

I always start with 1/2 (if reduction) because it is most common.

3 divided by 2 = 1.5

/0.5 as a fraction is 1/2

The tree diagram that represents the events is an illustration of probability and combination

To draw the tree diagram, we make use of the following representations:

See attachment for the tree diagram.

From the tree diagram, the sample space is as follows:

S = {HR, HY, HB, TR, TY, TB}

The number of outcomes that represents "Toss a tail, spin yellow"

This is represented as: TY

From the sample space above, we have:

TY = 1

Hence, the number of outcomes that represents "Toss a tail, spin yellow" is 1

We have:

Hence, the probability of tossing tails and spinning yellow is 1/6

Answer:

900

Step-by-step explanation:

Absolute value of any number comes out to be a non-negative value. Thus, the answer is 900

Answer:

The absolute value of -900 is 900.

Step-by-step explanation:

When you're solving an absolute value it just means to remove any negative sign in front of a number.

For example, The absolute value of −5 is 5

If there is no negative sign live this number the way it is.

For example, The absolute value of 3 is 3

Answer:

432 cm

Step-by-step explanation:

the circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

If the radius is multiplied by 9 then the circumference will also be increased by a factor of 9

given C = 48 cm

then circumference of new circle = 9 × 48 cm = 432 cm

Answer:

10 times

Step-by-step explanation:

This is a ratio problem.

We can see from the chart that out of the 36 possible choices, rulling a sum of three is 2. Therefore that fraction would be 2/36, about two times out of the thirty six times rolling would be a three.

Now, they're asking us how many times the sum will be three when the dice are rolled not just 36 times but 180. Therefore we can set up a ratio. We need to do this to find out how many times Tamara can expect to roll a three when she's rolling a total of 180 times.

2/36 = X/180

To solve for X we multiply 180 on each side:

(2/36)(180)=10=X

Therefore, when Tamara rolls the dice 180 times, she can expect the sum to be three 10 times.

Answer:

The answer is 12.

Step-by-step explanation:

A straight line is 180. Adjacent angles in that line equal 180. Add 10x-20 and 6x+8, which equals 16x-12. Make 16x-12 equal to 180 and add 12. 16x=192, divide both sides by 16 and x=12

Answer:

So basically you can split the figure up into a couple of shapes. So what you want to do is find out what the area of one rectangle is, a rectangles formula is base x height, and thats 8x4, which is 32, and then you have 2 rectangles so you do 32x2, which is 64, and then, triangles. Triangles formula is 1/2 (bxh), (its 1/2 because a triangle is half of a rectangle) so you want to find out 7 - 4, because one side is 7 but from the rectangle you can see there is 4 already there, so then you do 7 - 4 = 3, then you do 3 x 8 = 24 divided by 2, and then you get 12, but since you have 2 triangles you can keep it at 24.

So now all you do is 24 plus 64 which is 88!

Hope this helps!!!!!!!!!

Answer:

well, a supplementary angle is two angles that sum up to 180 degrees. If one angle is 8, then the other angle would be found by using 180-8=? Or ?+8=180. Because of this, the other angle would equal 172
