Answer:
65 miles per gallon
Step-by-step explanation:
To determine the number of miles per gallon, take the total number of miles driven and divide by the number of gallons used
292.5 miles/4.5 gallons
65 miles per gallon
Sunni is riding a raft down a stream that is moving at a rate of 75 feet per minute how far downstream does she travel in 5 minute?
Answer: 375 feet
Step-by-step explanation:
From the question, we are given the information that Sunni is riding a raft down a stream that is moving at a rate of 75 feet per minute.
To calculate how far downstream that she can travel in 5 minute, we have to multiply the distance covered per minute by 5. This will be:
= 75 feet × 5
= 375 feet
Aaron bought 7 packs of balloons for the party. There were 50 balloons in each bag. 40 of the total number of balloons were yellow. How many balloons were not yellow?
Answer:
[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]
Answer:
310
Step-by-step explanation:
The equation that we would use to solve this problem is 7 × 50 - 40 = b
(b is the number of non-yellow balloons)
Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.
7 × 50 = 350.
Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.
350 - 40 = 310

what is the measure of angle B in degrees?
Answer:
119°
Step-by-step explanation:
51+180-112= 119°
------
We know that,
[tex]\sf\purple{Sum\:of\:angles\:on\:a\:straight\:line}[/tex] = 180°
➡ ∠ C + 112° = 180°
➡ ∠ C = 180° - 112°
➡ ∠ C = 68°
Also,
[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle}[/tex] = 180°
⇝ ∠ A + 51° + 68° = 180°
⇝ ∠ A + 119° = 180°
⇝ ∠ A = 180° - 119°
⇝ ∠ A = 61°
Again,
[tex]\sf\blue{Sum\:of\:angles\:on\:a\:straight\:line}[/tex] = 180°
✒ ∠ A + ∠ B = 180°
✒ 61° + ∠ B = 180°
✒ ∠ B = 180° - 61°
✒ ∠ B = 119°
Hence, the measure of angle B is 119°.

In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?
Answer:
B. B = 70.5° or B' = 109.5°
Step-by-step explanation:
(sin 45°)/13.5 = (sin B)/18
sin B = (18 * sin 45°)/13.5
sin B = 0.9428
B = sin^-1 0.9428
B = 70.5°
B' = 180° - 70.5°
B' = 109.5°

Find the lateral and surface area of the figure.
Answer:
A.
Lateral area (LA) = 324 cm²
Surface area = 432 cm²
Step-by-step explanation:
✔️Lateral area of the triangular prism = perimeter of the base (P) × height of prism (L)
Perimeter (P) = 9 + 12 + 15
Perimeter (P) = 36 cm
height of prism (L) = 9 cm
Lateral area (LA) = 36 × 9 = 324 cm²
✔️Surface area = bh + LA
b = 9 cm
h = 12 cm
LA = 324 cm²
Surface area = 9*12 + 324
= 108 + 324
Surface area = 432 cm²
To estimate the proportion of brand-name lightbulbs that are defective, a simple random sample of 400 brand-name lightbulbs is taken and 44 are found to be defective. Let X represent the number of brand-name lightbulbs that are defective in a sample of 400, and let PXrepresent the proportion of all brand-name lightbulbs that are defective. It is reasonable to assume that X is a binomial random variable.
Requried:
One condition for obtaining an interval estimate for Px is that the distribution of Px is approximately normal. Is it reasonable to assume that the condition is met?
Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met

Step-by-step explanation:
20 men can complete a piece of work in 24 days how many men should be subtracted to finish the work in 32 days?
Answer:
5 men should be subtracted.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.
How many men should be working to complete the work in 32 days?
20 men - 24 days
x men - 32 days
Then
[tex]32x = 20*24[/tex]
[tex]x = \frac{20*24}{32}[/tex]
[tex]x = 15[/tex]
How many men should be subtracted?
There are 20 to complete in 24 days.
15 are needed to complete in 32 days.
20 - 15 = 5
5 men should be subtracted.

From the sample space S = a single number is to be selected at random. Given the following events, find the indicated probability.
A: The selected number is even.
B: The selected number is a multiple of 4.
C: The selected number is a prime number.
P(Aand B)
P(A and B) =
(Simplify your answer.)
Answer:
P(A and B) = 1/5 = 0.2
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we want to find the probability of taking a number that is even and a multiple of 4.
We have the following sample space, of five numbers: {1,2,3,4,15}.
One of these numbers, 4, is even and a multipled of 4.
P(A and B)
1 out of 5. So
P(A and B) = 1/5 = 0.2
