Answer:

[tex]angle Q = about 45\\\\\\angle R= about 19\\\\angle S= about 127[/tex]

Looking at these angles, the type of this triangle is an obtuse triangle.

Step-by-step explanation:

First, sum up all the angles to 180 (because any triangle's angles sum up to 180).

[tex]4x-17 +x+5+10x-4 = 180[/tex]

Next, combine like terms:

[tex]15x -16 = 180[/tex]

Solve:

[tex]15x = 196\\\\x = 196/15[/tex]

After that, plug x into the angles equations

[tex]angle Q \\4*(196/15) -7 = about 45\\\\\\angle R\\196/15 + 6 = about 19\\\\angle S\\10*196/15 - 4 = about 127[/tex]

Since 127 is obtuse, this triangle is obtuse.

I hope this helps, but I am unsure if it is correct.

Answer:

B

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

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:

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: 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

Step-by-step explanation:

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:

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

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

Answer:

A. 40.82 cenimeters

Step-by-step explanation:

[tex]\text{According to the condition, circumference,}\\\\~~~~~~~C_1=2\pi r=48~~~~~~~~~~~~~~~~...(i)\\\\\\~~~~~~~C_2 =2\pi \cdot(9r) =18\pi r~~~~~~...(ii)\\\\(ii) \div (i)\\\\~~~~~~\dfrac{C_2}{C_1} = \dfrac{18\pi r}{2\pi r} \\\\\\\implies \dfrac{C_2}{48}= 9\\\\\\\implies C_2 = 48\times 9\\\\\\\implies C_2 = 432~ \text{cm}\\\\\text{Hence, the new circumference is 432 cm.}[/tex]

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:

[tex]x\leq -8[/tex]

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].

Hope this helped.

Answer:

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

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.

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
