Answer:

5 meters bc you just multiply it by 2

Answer:

9

Step-by-step explanation:

V=pi (r squared) (h/3)

75pi = 25pi (h/3)

Divide both sides by 25 pi

3= h/3

Multiply both sides by 3

h=9

Step-by-step explanation:

Using the formulas

A=πr2

d=2r

Solving forA

A=1

4πd2=1

4·π·162≈201.06193

Answer:

32

Step-by-step explanation:

Pythagorean theorem

[tex]a^{2} + b^{2} =c^{2}[/tex]

a = perpendicular

b = base

c = hypotenuse

we have to find the hypotenuse

so,

[tex]13^{2} + 29.25^{2} = c^{2} \\169 + 855.6 = c^{2}\\1024.6 = c^{2}\\\sqrt{1024.6} = \sqrt{c^{2}} \\c = 32[/tex]

Answer:

x = 6

Step-by-step explanation:

Tip: You want to isolate the x-variable on one side of the equation to find its value.

1) First, get rid of the radical signs on both sides of the equation by squaring both sides. This should leave you with 5x-7 = 3x+5.

2) Get the x-variables on one side by subtracting 3x from both sides, so the equation should be 2x-7=5.

3) Solve for x by adding 7 to both sides, so that your equation looks like this: 2x = 12.

4) Divide both sides by 2 and you will get x = 6. You can verify 6 as the x-value by plugging 6 back into the original equation.

I hope that helps! :)

Answer:

x=6

Step-by-step explanation:

Answer:

Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

Step-by-step explanation:

Vertical angles are diagonally across for each other and equal the same angle. You would get a better explanation if you looked up pictures.  

Linear angles are two angles on a straight line that are divided by another line. Again, you would get a better explanation by looking at a visual

Congruent angles are equal to each other, and because there are no angle measures here, you would go with a vertical angle pair.

Answer:

Step-by-step explanation:

Vertical angles: <3 and <8, <2 and <5, <1 and <6, <4 and <7 (choose one pair, these are all right)

Linear: <1 and <5, <2 and <6, <3 and <7, <4 and <8, there are more (choose one pair, all these are right)

Congruent: Choose one of the vertical angle pairs I listed above

Answer:

the answer is (-3,0) or 4

Step-by-step explanation:

Answer:

1. D= 46 degrees

2. X= 50 degrees

3. X= 180-118 = 62 degrees

4. X = 90-75 = 15 degrees.

Step-by-step explanation:

Answer:

Going by the order from the first row left to right and then second row left to right

1) D=46

2) x=62

3) x=50

4) x=15

5) b=40

Step-by-step explanation:

So for the first column for the first question its a complementary angle which means 2 or more angles added up to from a 90 degrees angle. We got 44 degrees already and an unknown angle which will lead to 90-44= 46 and that 46 degrees is your answer. D will be equal to 46.

For the second question on the first column, you have 2 angles forming a straight line. This is a s upplementary angle which means 2 or more angles added up to from 180 degrees. You have 1 angle already which is 118 and to find the other angle, 180-118 which will be 62. X will equal to 62

For the thrid question which is the first question on the SECOND column, you have another supplementary angle. You have 130 and 180-130=50 and X will equal to 50.

For the 4th question you have a complementary and one angle is 75. You do 90-75 and get 15. X will equal to 15.

The last question which is the huge rectangle on the right, you have 2 intersecting lines. We know one side is 40. Well the only thing that makes sense here is B=40 since its vertical to the one angle given. Vertical angles are equal so therfore the answer is b=40

Answer:

Radius:2

Diameter:4

Area:12.56

Circumference: 12.56

Answer:

$444

Step-by-step explanation:

1.99 * x = 883.56  [The price has increased by 99%, so you multiply it by 1 + 0.99]

x = 444

Answer:

The original price of the calculator was $444

Step-by-step explanation:

So follow this equation

1.99x=883.56

1.99 becuase 99 percent is the .99 and since the original price with no change of all is worth 100 percent With no sales or increases, we add the 99 percent this time becuase it increased by 99%.

X is for the original price of the calculator

If you still don’t undertsand it works like this.

100% is basically 1.00 becuase you move the decimal place 2 times to the left for percentages. And if you multiply the original price by 100 percent, its basically 1x which will end up with x. Same thing. But when you increase a price, you add to the 1.00 like in this case 99% increase which is adding .99 to 1.00. If it decreases same thing except you subtract from that 1.00 But the percent. this saves a whole nother step Which makes percentage questions liek these much quicker and easier.

Alright so the eqaution is 1.99x=883.56

Solve by isolating x by dividing 1.99 on both sides

You’d get 444=x

$444 is the original price

Answer:

37.68

Step-by-step explanation:

Circumference = Diameter x pi

Diameter = 12 feet

12 x 3.14 = 37.68

The circumference of the pool is 37.68 feet.

Answer:

x = 3

y = 12

Step-by-step explanation:

(2x+1) / 3 = (4x+9) / 9

cross-multiply:

18x + 9 = 12x + 27

6x = 18

x = 3

3/4 = 9/y

3y = 36

y = 12

Answer: 17.5%

Step-by-step explanation:

Percentage of chips given to Jackie = 20%

Percentage of chips given to Ronald = 20%

Percentage of chips given to Mark = 1/4 × 100 = 25%

From the above calculation, we can see that Ms Johnson has given out ((20% + 20% + 25%) = 65% worth of chips out. The percentage she'll have left will be:

= 100 - 65

= 35%

Since Susan takes half of what's left, the percent that Ms. Johnson has left to eat will be:

= 1/2 × 35%

= 17.5%

She has 17.5% left to eat.
