Answer 1

Answer:

The measure of angle a is 45 degrees.

Step-by-step explanation:

Notice that since PS = RS, this is an isosceles triangle. This means that the base angles are equal. We also know that the sum of interior triangles of a triangle equals 180, then, if 'a' is the base angle, we have the following equation:

90 + a + a = 180

2a = 180 - 90 = 90

a = 90/2 = 45

a = 45

wait a min i searched it up and it '=' to decimals. What does this equal to in fractions?

Answers

Answer: 12/55
Because: I did the math

Answer:

15/11 or 1 and 4/11

Step-by-step explanation:

I like to use the trick "Keep it, change it, flip it." for division of fractons.  So keep 6/11 how it is, change the division sign to multiplication, and change 2/5 to 5/2, (Basically just flipping it.) Now multiply like how you would multiply fractions.  Multiply numerators , (6 and now 5) by eahother and denominators, (11 and now 2,)  by eachother as well.  You get 30/22, which simplifies to 15/11.  The mixed number version is 1 and 4/11 if you need that instead.    

I hope this helps so that you don't have to search it up again!

Answer:

So solution: [tex]6(x=2)+2(y=1)=14[/tex] and [tex]5(x=2)-2(y=1)=8[/tex]

([tex]x[/tex])=2

([tex]y[/tex])=1

Step-by-step explanation:

Because, 6[tex]x=2[/tex] + 2[tex]y=1[/tex] = 14 | 6 * 2 = 12 | 2 * 1 = 2 | 12 + 2 = 14 |

Because 5[tex]x=2[/tex] - 2[tex]y=1[/tex] = 8 | 5 * 2 = 10 | 2 * 1 = 2 | 10 - 2 = 8 |

So that's why the answer is ([tex]x[/tex])=2, and ([tex]y[/tex])=1

How do you find the diameter of a sphere if you have the volume. Will give Brainliest

Answers

Answer:

Diameter  of a sphere formula is  d=2 * r

Step-by-step explanation:

Answer:

d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2) (see below for explanation)

If volume = 34, d ≈ 4

Step-by-step explanation:

The volume of a sphere is:

V = (4/3) · π · r³

To find the diameter, you need to find the radius first. Isolate it to one side:

[tex]\frac{V}{(4/3)(pi)}[/tex] = r³

r³ =  [tex]\frac{V}{(4/3)(pi)}[/tex]

∛r³ =  ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]

r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]

So you would first multiply 4/3 by pi, then divide volume by that. Then cube root the whole thing. This will get you the radius.

Double this. This will get you the diameter.

r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]

d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2)

If the volume is 34, then:

d = {∛ [tex]\frac{34}{(4/3)(pi)}[/tex]} x (2)

4/3 (pi) = 4.188...

34/41.88... = 8.116...

∛8.116... = 2.009...

2.009...(2) = 4.019...

d = 4.019389542

d ≈ 4

Quinn's mom went to the same middle school that Quinn is now attending. The current student population is 817 students. Since Quinn's mom attended, the school has experienced a
57% increase in population. About how many students were enrolled at the school when Quinn's mom attended?

Answers

Answer:

520

Step-by-step explanation:

Past number of pupils: p

Increase of 57% = 1.57

Present number of pupils = 817

p x 1.57 = 817

p = 817 divided by 1.57 = 520.382

rounded to the nearest whole number = 520 (this is why the question says "about" how many...)

57 x 817 = 46569

46569 divided by 100 = 465.69

817-465.69 = 351.31

Answer : 351

Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 .
