7 blocks i think
Step-by-step explanation:
n/5 + 7 < 5
I need help please!
Let's solve your inequality step-by-step.
n/ 5 + 7 < 5
Step 1: Simplify both sides of the inequality.
1/5n + 7 < 5
Step 2: Subtract 7 from both sides.
1/5n + 7 −7 < 5 − 7
1/5n < − 2
Step 3: Multiply both sides by 5.
5*(1/5n) < (5)*(−2)
n < − 10
Answer:
n < − 10
Question
Translate and solve: Twelve less than x is equal to 51. Enter the equation
Answer:
x = 63
Step-by-step explanation:
From the question, we can deduce the following points;
- 12 less than x which simply means 12 subtracted from x.
- the value of the above expression is equal to 51.
Translating the word problem into an algebraic expression, we have;
x - 12 = 51
Rearranging the equation (collecting like terms), we have;
x = 51 + 12
x = 63

Answer:
sin 60 =√3/2 = 0.8660
Step-by-step explanation:
sin 60 = opposite/hypotenuse
sin 60 = x√3/2x
sin 60 = √3/2 since x cut x
sin 60 = 0.8660 or √3/2

Answer:
12.25 (or -18.75)
Step-by-step explanation:
If you pay attention to the square of a binomial, ...
(x -a)² = x² -2ax +a²
You see that the constant (a²) is the square of half the x-coefficient. That is, the x-coefficient is -2a, half that is -a, and the square of that is (-a)² = a².
In your equation, the x-coefficient is -7, half that is -3.5, and the square of that is 3.5² = 12.25.
So, you can think of this ambiguous question in a couple of ways.
Concern is only with the x-terms:
x² -7x +31 = (x² -7x +12.25) +31 = 12.25 . . . . . . add 12.25 to both sides
(x -3.5)² +31 = 12.25 . . . . write the x-terms as a square
Concern with the equation overall:
You want the end result to have the x-terms in the form of the square ...
(x -3.5)² = x -7x +12.25
The left side of the equation can be put in that form by adding -18.75 to both sides;
x² -7x +31 -18.75 = -18.75 . . . . . . add -18.75 to both sides
x² -7x +12.25 = -18.75 . . . . . . . . . simplify
(x -3.5)² = -18.75 . . . . . . write the left side as a square
__
The short of it is that we're not sure what the question is asking for exactly. The "help video" would probably clarify the intent. Most likely, you're concerned with adding the square of half the x-coefficient, 12.25.

All employees in Department A attend the sales training programme. Some employees in Department A attend the technical training programme. Some employees who attend both training programmes are in Department B. Conclusion: All employees who attend the sales training programme and who attend the technical training programme are in Department A. If the assumptions are true, is the conclusion:
a. Correct
b. Cannot be determined based on the information available
c. Incorrect
Answer:
c. Incorrect
Step-by-step explanation:
According to the third sentence in assumption "Some employees who attend both training programmes are in Department B.", it is clear that there are certain employees in department B, who are attending both the training. Hence, all the employees who attend the sales training programme and who attend the technical training programme are not in Department A. Some of them are in department B as well.
Therefore, the conclusion is not correct and the final answer is:
c. Incorrect

A father has four sons, with heights of 68, 71, 72, and 75 inches. Determine the sampling distribution of
the sample mean height and the sampling distribution of the sample range of height for samples of
size n= 2.
The sampling distribution of the sample mean height and the sampling distribution of the sample range of height are 71.5 inches and 7 inches.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Heights: 68, 71, 72, and 75 inches
Now,
Mean height.
= (68 + 71 + 72 + 75) / 4
= 286/4
= 71.5 inches
Sample range.
= Highest height - Lowest height
= 75 - 68
= 7 inches
Thus,
The mean height is 71.5 inches.
The sample range of height is 7 inches.

Hello! answer: x = 37
These are vertical angles so they will both equal the same so we just have to figure out what multiplied by 4 + 2 = 150 and 4 × 37 = 148 and 148 + 2 = 150 so x = 37 Hope that helps!

The admission fee at an amusement park is $3.50 for children and 13.00 for adults. On a certain day, 288 people entered the park, and the admission fees collected totaled $2,338.00. How many children and how many adults were admitted?
There were ___ children and ____ adults admitted into the park
Answer:
148 children and 140 adults were admitted.
Step-by-step explanation:
Given that the admission fee at an amusement park is $ 3.50 for children and $ 13.00 for adults and on a certain day, 288 people entered the park, and the admission fees collected totaled $ 2,338.00, to determine how many children and how many adults were admitted you must be perform the following calculation:
13 - 3.5 = 9.50
288 x 3.50 = X
1.008 = X
2338 - 1008 = 1330
1330 / 9.5 = 140
288 - 140 = 148
148 x 3.5 + 140 x 13 = X
2338 = X
Therefore, 148 children and 140 adults were admitted.

Determine if lines AB and CD are parallel, perpendicular, or neither. A(5,-8), B(-2,-10), C(-6,-13), D(-2,1)
Answer: The answer is neither because the slopes are 2/7 and 7/2.
Step-by-step explanation:
While these answers look like they are perpendicular, they are not since the signs are the same. If they were perpendicular the signs would be different. Ex: 2/7 and -7/2. These points are perpendicular since their signs changes as well as being "flipped".

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
So as we see here, they all look the same. But I can see that it says only ONE of the PAIRS of triangles is congruent.
What I can tell is that
Number 1 and 3 are probably congruent since they both have the same shape, and size.

Which table shows the same relationship as y = -x^2 + 3x?
Answer:
H
Step-by-step explanation:
given y = -x² + 3x.
let f(x) be y.
f(-2) = -(-2)² + 3(-2) = -10
f(-1) = -(-1)² + 3(-1) = -4
f(0) = -(0)² + 3(0) = 0
f(1) = -(1)² + 3(1) = 2
f(2) = -(2)² + 3(2) = 2
