Answer:
3 1/5 = 16 / 5
1 1/2 = 3 / 2
16 / 5 * 3 / 2 = 48 / 10 = 24 / 5

A cone has a radius of 7 cm and a height of 12 cm what is the volume in cubic meters of the cone
Answer: 615.44 m^3.
Step-by-step explanation: To find the volume of a cone, you need to multiply the radius, pi, and height. The equation is given below:
π x r^2 x h = V, where π is pi, r is the radius squared, h is the height, and V is the volume.
Now, we need to substitute the values with the information that is given. π ≈ 3.14:
3.14 x 7^2 x 12 ≈ 1846.32.
We are not finished yet! A cone's volume is a third of a cylinder's, so you need to split 1846.32 in 1/3:
1/3 x 1846.32 ≈ 615.44 m^3.
Hope this helps! :)
Which expression could be placed in the box as an example of the reflexive property?
9x + 27 = 2 A. 9(x + 3) B. 27 + 9x C. X * 9 + 27 D. 9x+ 27
Answer:
A.
Step-by-step explanation:
The reflexive property (of equality/of congruence) states that a number must always be equal to itself.
Because A is the only statement with an = sign, that's the answer.
Noah walked a family’s dog 5 times this past month and earned the same amount each time. To thank him, the family gave him an extra $6 at the end of the month. Noah earned $106 from dog walking.
1- This situation IS represented by the tape diagram.
2- This situation IS NOT represented by the tape diagram.
The situation IS NOT represented by the tape diagram.
How to represent the situationNumber of times Noah walked the dog = 5Amount earned each time = sExtra amount earned = $6Total amount earned = $106The situation can be represented by the equation:
s + s + s + s + s + 6 = 106
5s + 6 = 106
5s = 106 - 6
5s = 100
s = 100/5
s = 20
Therefore, the amount Noah earned each time he walked the dog is $20

A log is partly buried in the mud. One third of the log is buried and 8 meters of the log are above ground. What is the total length of the log?
Answer:
12
Step-by-step explanation:
The answer is 12 because if 1/3 of the log is buried then 2/3 of the log is 8 meters. 8 divided by 2 is 4 so you know that 1/3 of the log is 4 meters. Then you just multiply 4 times 3 or add 4 and 8.
Answer:
12 meters
Step-by-step explanation:
see image. If 1/3 log is buried, then 2/3 (the rest of it) log is above ground. If 8meters of log is 2/3 of the log, that is 8 meters is 2 parts, then each part is 4 meters.
2 parts (thirds!) above ground:
8 meters
1 part (one-third) below ground:
4 meters
Total is 8 + 4 =12
or 3×4 = 12
The whole log is 12 meters.

What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
The vertex form of parabola :
y=a(x−h)²+k
(h,k)is the vertex of the parabola, and
Substitute vertex(2,-3), into equation
y = a(x−2)²-3
Substitute a = 3 into equation
y = 3(x−2)²-3
Here is a graph of the y = 3(x−2)²-3

Help picture below problem 10
Solution :-
Here, we have been given that lines f and g are parallel. Thus, the angle measuring 135° and ∠2 are vertically opposite angles.
And we know that vertically opposite angles measure same. Thus,
∠2 = 135°
And,
∠2 + ∠6 = 180° ( Co - interior angles sum up to 180° )
135° + ∠6 = 180°
∠6 = 180° - 135°
∠6 = 45°

Shaquana owns a small business selling bagels. She knows that in the last week 93 customers paid cash, 7 customers used a debit card, and 5 customers used a credit card.
Based on these results, express the probability that the next customer will pay with cash as a decimal to the nearest hundredth.
Answer:The probability as a decimal to the nearest hundredth is 0.89
Step-by-step explanation:
i just did it and got it right
The probability that the next customer will pay with cash as a decimal to the nearest hundredth is 0.89
What is probability?"Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are."
What is decimal?"A decimal is a fraction written in a special form. Instead of writing [tex]\frac{1}{2}[/tex], for example, you can express the fraction as the decimal 0.5, where the zero is in the ones place and the five is in the tenths place."
We have
Customers paid cash = 93
Customers used debit card = 7
Customers used credit card = 5
Number of favorable outcomes n(S)
= 93
Total number of outcomes n(E)
= 93+7+5
= 105
The probability that the next customer will pay with cash
= [tex]\frac{n(S)}{n(E)}[/tex]
= [tex]\frac{93}{105}[/tex]
= [tex]0.885[/tex]
= 0.89 (nearest hundredth)
Hence, the probability that the next customer will pay with cash as a decimal to the nearest hundredth is 0.89.
