the cubes of interest are the cubes of 5, 6, 7, 8, 9 — a list with 5 elements
Step-by-step explanation:
The integers that have 3-digit cubes will be between ...
∛100 = 4.6 and ∛999 = 9.99
That is, the 3-digit cubes will be the cubes of 5, 6, 7, 8, 9. There are exactly 5 numbers on this list.

Find the value of x.
Answer: 150 degrees
Step-by-step explanation:
The line around the angles that measure 35 degrees shows that those are equal so both are 35 degrees. Then you add 35+35+140. You then subtract that value from 360 since a whole circle measures 360 degrees.
Akiko ate 60 hot dogs in 10 hours. At that rate, how many hot dogs would she eat in 20 minutes?
Akiko ate per hour:-
Total hot dogs/Total hours60/106dogs/hourSo
20min=1/3h
Total hot dogs
6/32Answer:
2 hot dogs
Step-by-step explanation:
Total hot dogs she ate in 10 hours,
→ 60 hot dogs
Total hot dogs she ate in 1 hour,
→ 60/10
→ 6 hot dogs
The fraction of 20 minutes in a hour,
→ 20 minutes/1 hour
→ 20/60
→ 2/6 = [ 1/3 ]
Rate of hot dogs she ate in 20 minutes,
→ 6 × 1/3
→ 6/3
→ [ 2 hot dogs ]
So, Akiko ate 2 hot dogs in 20 minutes.

Someone help The question is to find the volume of the cylinder in terms of pi. The formula for Volume is V=pi*R^2*H right? Radius is 3.4m and the height is 11m So i got 399... Around but none of those are the answer choices i know when questions ask in terms of pi, i always get confused can anyone help me please?! A.) 127.16 B.) 74.8 C.) 432.34 D.) 63.58 P.S - pi is after each answer
Answer:
A.) 127.16π
Step-by-step explanation:
Volume of a cylinder = πr²h
Radius, r = 3.4m
Height, h = 11m
Pi = π
Find the volume in terms of pi
Volume of a cylinder = πr²h
= π * (3.4)² * 11
= π * 11.56 * 11
= 127.16π³
The correct answer is
A.) 127.16π

Jorges car wash offers a weekend special on sand washes on cars, trucks , and SUVs. you can also chooses between wax, vacuum, and interior cleanings. how many different car washes can you make for the weekend?
Answer:
9 different car washes
Step-by-step explanation:
From the services that Jorge offers we can see that there are 3 options (wax, vacuum, and interior cleanings) on 3 different categories of vehicles (cars, trucks, and SUV). Therefore, in order to calculate the number of possible combinations or car washes that you can make, we need to multiply the number of options by the number of categories of vehicles. Like so...
3 * 3 = 9
Therefore, we can see that there are a total of 9 different car washes that you can make for the weekend.

A projectile is launched from a tower 64 feet above the ground into the air with an initial velocity of 48 feet per second. How many seconds is the projectile in the air before it hits the ground?
Answer:
I hope this helps you
Step-by-step explanation:
To define the time of flight equation, we should split the formulas into two cases:
Launching projectile from the ground (initial height = 0)
t = 2 * V₀ * sin(α) / g.
Launching projectile from some height (so initial height > 0)
t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

4/5 - 1/10=
A. 7/10
B.3/5
C.3/10
D.2/25
Answer
A 7/10
Step-by-step explanation:
if you make it even, you double the 4/5 to make it a 8/10, if you every have a number that is like 4/6-2/18, you triple the 4 to make 12, and triple the 6 to make it 18. so you now have 12/18-2/18=10
So 8/10-1/10=7/10

Translate algebra expressions 2 less that 3 times z
Answer:
(3z) - 2
Step-by-step explanation:
Let's see an example:
(4x) - 6
This translates into 6 less than 4 times x
So... 2 less than 3 times z =
(3z) - 2
Answer:
Step-by-step explanation:
That would be "3z - 2:" 2 less than 3 times z.

The cross section of a right cylinder that is perpendicular to the base of the cylinder is in the shape of a rectangle
The cross section of a right cylinder that is neither parallel nor perpendicular to the base of the cylinder is in the shape of an ellipse which is a form of an oval shape.
In ABC m /_A = 65° and m/_B= 80°
Select the triangle that is similar to ABC
Answer:
C is the correct answer.
Step-by-step explanation:
All of the angles in a triangle add up to 180 degrees. 65+80=145 and when you do 180-145, you get 35 degrees. You can check to see if it's correct by adding 35, 65, and 80 together.
[tex]65+80=145[/tex]
[tex]180-145=35[/tex]
[tex]35+65+80=180[/tex]
The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC. Option C is correct.
What exactly is a triangle?
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
ΔDEF
∠F=80°
∠F=35°
The sum of the angle of the triangle DEF is;
∠D+∠E+∠F=180°
∠D=180°-115°
∠D=65°
In ABC
/_A = 65°
/_B= 80°
∠A+∠B+∠C=180°
∠D=180°-145
∠D=35°
The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC.
Hence,option C is correct.

Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom bought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups.
Answer:
Cups = 24
Plates = 48
Balloons = 12
Total = 84
Step-by-step explanation:
Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom brought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups. If Serena's mom bought 84 items, how many of each item did she buy.
Let
c = number of cups
Serena's mom bought twice as many plates as cups.
2c = number of plates
number of balloons Serena's mom bought was half the number of cups
0.5c = the number of balloons
Total items = 84
c + 2c + 0.5c = 84
3.5c = 84
Divide both sides by 3.5
3.5c / 3.5 = 84 / 3.5
c = 24
c = number of cups = 24
2c = number of plates = 2 * 24 = 48
0.5c = the number of balloons = 0.5*24 = 12
Cups = 24
Plates = 48
Balloons = 12
Total = 84

Tyler has a stack of cards. He picks a card, records the color, and returns the card to the stack. He repeats this 60 times and chooses a red card 24 times. What is the experimental probability of choosing a red card from the stack?
Answer:
24/60 = 2/5
Step-by-step explanation: dont have one
Answer:
2/5, or 40%
Step-by-step explanation:
The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.
