Answers

the formula to use for this equation would be a²+b²=c². in this case, a is 11, b is 9.2, and c is the side you are looking for. so you do 11²+9.2²=c². simplify that and you get 205=c². now square root both sides and you get 14.32=c. the height of the triangle is 14.32. hope this helps

1. A professional basketball used for league play has a diameter of 25 cm. Which of the following is closest to the volume of the basketball in cubic centimeters?​

Answers

Answer:

V = 8,181.23 [tex]cm^{3}[/tex]

Step-by-step explanation:

Unfortunately, we are not given any answer choices to choose from but using the information provided we can find the actual volume of the basketball. A basketball is made in the shape of a sphere and the formula for the volume of a sphere is the following...

V = [tex]\frac{4}{3} * \pi * r^{3}[/tex]

radius of a circle/sphere is half of it's diameter. Since we are provided the diameter size we simply divide it by 2 which would give us 12.5cm. Now we simply plug this value into the formula and solve for V.

V = [tex]\frac{4}{3} * \pi * 12.5^{3}[/tex]

V = [tex]\frac{4}{3} * \pi * 1953.125[/tex]

V = 8,181.23 [tex]cm^{3}[/tex]

hey please help me with the answer​

The answer would be 6 because when you plug it in it becomes 3+7-4 which is 6

Question 8
Calculate the difference (4x2 + x - 5) – (5x2 - 1).

Answers

Answer:

x - 6

Step-by-step explanation:

(4x2 + x - 5) - (5x2 - 1)

According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.

Then we do the multiplication because it comes before addition and subtraction.

4x2 = 8

Now we have 8 + x - 5

Combine like terms and 8-5=3 so we have 3 + x

Now for the second one.

5x2=10

10-1=9

Subtracting this from the first expression we have:

3+x-9 =

x - 6

Answer:

Okay the ratio of starfish to fish is 3:6 or 3/6 but simplified it is 1/2

The starfish ratio to 16 fish would be 8 or 16:8

and if there was one less starfish in the line the ratio would be 2:6 or 2/6 but simplified would be 1/3

Step-by-step explanation:

Okay to solve the first question we see that there are 6 fish and 3 starfish, when put into a ratio it is 3:6 (the reason the number of starfish is first in the ratio is because it is starfish to fish hence starfish goes first ). If you are wanting the ratio to be in fraction form you are going to put 3/6 and since 3 goes into 3 once and 6 twice so the fraction is 1/2

3:6 = 3/6 = 1/2

Since the ratio from starfish to fish is 1/2 of that number you are going to divide 16 by 1/2 or more like multiply:

16/ 1/2 = 16/1 * 1/2 = 16/2 = 8

I hope this helps you!!!

When the ratio of starfish is short of one then the ratio would be 2: 6 or in fraction form 2/6 but simplified is 1/3.

2:6 = 2/6 = 1/3

Alice likes to go to Main Event to play laser tag and climb the rock wall each Saturday. Instead of purchasing the play pass, Alice pays for each activity separately.


a. This week Alice played laser tag twice and climbed the rock wall 3 times, spending $31.


b. Last week Alice played laser tag 4 times and climbed the rock wall once, spending $27.


Using the information provided, how much does Main Event charge, in dollars, to climb the rock wall?


1. $7

2. $5

3. $8

Answers

Answer:

1. $7 for climbing the rock

Step-by-step explanation:

x is the number of laser tags

y is the number of times climbed the rock

a. 2x + 3y = 31

b. 4x + y  =27

lets find y

Step 1

4x + y = 27

y = 27 -4x

step 2

replace y with 27 - 4x in the a.

2x + 3( 27 - 4x) = 31

2x + 81 - 12x = 31

2x -12x = 31 -81

x = 5

y = 27 - 4(5)

y = 7
