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

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 =

The drawing at the right shows a person,
5 feet tall, casting a shadow 3 feet long.
The tree is casting a shadow 15 feet long.
How tall is the tree?
Answers
Answer:
I would say the tree is 18 feet tall
Answer: 25 feet tall
Step-by-step explanation:
First, let's take a look at the person. If they are 5 feet tall and cast a shadow of 3 feet, we can easily convert this into a proportion: 5 feet tall: 3 feet shadow.
Continuing with this method, we can convert the tree into a proportion: x feet tall: 15 feet shadow.
So, 5:3=x:15. Mathematically, think of it as 5/3=x/15.
To find x, you will need to multiply 15 to both sides, or perform cross multiplication. (5/3)(15)=(x/15)(15). This will equal 25. The tree is 25 feet tall.

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]
