Answer:
22
Step-by-step explanation:
brainliest?
Answer:
The answer is 52
Step-by-step explanation:
the question is
30 minus 12 divided by 3 times 2
so start with 12 divided by 3 that would equal 4
30 minus 4 times 2
then go to 30 minus 4 that would be 26
26 times 2
and 26 times 2 would be 52
In a company there are 33 male and 42 female staff. Calculate the percentage of male and female staffs
Answer: 44%, 56%
Step-by-step explanation:
Given
A company has 33 males and 42 female staff
So, the total staff is the sum of male and female
[tex]\Rightarrow \text{Total=}33+42\\\Rightarrow \text{Total=}75[/tex]
The percentage of male staff is
[tex]\Rightarrow \text{Male }\%=\dfrac{33}{75}\times 100\\\\\Rightarrow \text{Male }\%=44\%[/tex]
The percentage of female staff is
[tex]\Rightarrow \text{female }\%=\dfrac{42}{75}\times 100\\\\\Rightarrow \text{female }\%=56\%[/tex]

Seth estimates that he will need about $9,100 for the first year of tuition for college. His grandparents will contribute 70% of the tuition expenses, and seth will need to save to pay for tthe rest. If seth has three years to save for his first year's contribution, what is the minimum amount that he should save each month?
Answer: $75.83
Step-by-step explanation:
Seth needs $9,100 and his grandparents will pay 70% of this:
= 9,100 * 70%
= $6,370
The amount Seth has to save for is therefore:
= 9,100 - 6,370
= $2,730
He has 3 years to save for it and wants to save monthly. In months this is:
= 3 * 12
= 36 months
Minimum amount to save every month is:
= Amount to save/ Number of months
= 2,730 / 36
= $75.83

Kevin is rolling two dice together and adding them up. Which sums should come up the most frequently?
Answer:
7 occurs most frequently.
Step-by-step explanation:
If we roll two dice, we do get sample space as
(1,1) = 1+1 =2 (4,1)=4+1=5
(1,2)= 1+2 =3 (4,2)= 34+2=6
(1,3)= 1+3=4 (4,3)= 4+3=7
(1,4)=1+4=5 (4,4)= 4+4=8
(1,5)=1+5=6 (4,5)= 4+5 =9
(1,6)=1+6=7 (4,6)= 4+6=10
(2,1)= 2+1=3 (5,1)= 5+1=6
(2,2)=2+2=4 (5,2)=5+2 =7
(2,3)= 2+3=5 (5,3) =5+3=8
(2,4)=2+4=6 (5,4) =5+4 =9
(2,5)=2+5=7 (5,5)=5+5=10
(2,6)=2+6=8 (5,6)=5+6=11
(3,1)=3+1=4 (6,1)= 6+1=7
(3,2)=3+2=5 (6,2)=6+2=8
(3,3)=3+3=6 (6,3)=6+3=9
(3,4)=3+4=7 (6,4) =6+4 =10
(3,5) =3+5=8 (6,5)=6+5=11
(3,6)=3+6=9 (6,6)=6+6=12
2 occurs for 1 time
3 occurs for 2 times
4 occurs for 3 times
5 occurs for 4 times
6 occurs for 5 times
7 occurs for 6 times
8 occurs for 5 times
9 occurs for 4 times
10 occurs for 3 times
11 occurs for 2 times
12 occurs for 1 time.
So, 7 occurs most frequently.

FILES DO NOT WORK FOR ME. I CAN NOT LOOK AT THEM. PLEASE TELL ME THE ANSWER AND TYPE THE WORK OUT> I NEED THE ANSWER ASAP!!!!!
Answer:
[tex]10^3[/tex] times
Step-by-step explanation:
Given
Let
[tex]P \to[/tex] Park Crest Middle School
[tex]T \to[/tex] Total
So, we have:
[tex]P = 400[/tex]
[tex]T = 406240[/tex]
Required
Determine the number of times T is greater than P
This is calculated by dividing T by P.
i.e.
[tex]n = \frac{T}{P}[/tex]
So, we have:
[tex]n = \frac{406240}{400}[/tex]
[tex]n = 1015.6[/tex]
Approximate
[tex]n \approx 1000[/tex]
As a power of 10, we have:
[tex]n = 10^3[/tex]
At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
Answer:
20.2 m
Step-by-step explanation:
At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.
We solve this question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 34°
Adjacent =30m
Opposite = Height of the flag pole = x
Hence
tan 34 = x/30
Cross Multiply
tan 34 × 30m
= 20.235255505 m
Approximately = 20.2 m
Hence, the height of the flag pole to the nearest meter = 20.2m
Please solve. Thanks.

Step-by-step explanation:
Given f’(x), where is f(x) increasing? Where is f(x) concave up?
Answer:
See explanation below
Step-by-step explanation:
a. f(x) is increasing at (-∞, 1] and [7, ∞) because f'(x) is positive at those intervals.
b. f(x) is concave up at [4, ∞) because the slope of f'(x) or f''(x) is positive.

Analyze the diagram below and complete the instructions that follow.
Find m
Answer:
D. 70.53
Step-by-step explanation:
To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]
Substitute,
[tex]cos(CBA) = \frac{3}{9}[/tex]
Simplify
[tex]cos(CBA) = \frac{1}{3}[/tex]
Inverse operations,
[tex]CBA=cos^-1(\frac{1}{3})[/tex]
Compute,
m<CBA = 70.53

Monica deposits $100 into a savings account that pays a simple interest rate of 4.1%. Paul deposits $200 into a savings account that pays a simple interest rate of 2.9%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she correct? Justify your response
Answer:
Paul
Step-by-step explanation:
Paul earn more than monica. Though he is getting less interest but because of his higher initial amount he is getting more return.
Computing the return of both
Monica return is 100*3.4%= $3.4 in a year
9514 1404 393
Answer:
Monica is not correct
Step-by-step explanation:
Monica's interest is ...
I = Prt
I = $100(0.041)(1) = $4.10
__
Paul's interest is ...
I = $200(0.029)(1) = $5.80
__
Paul's account earns more interest because of his greater initial deposit. Monica's statement is incorrect.
Simplify the following
= 10^1÷2/10^1÷4
= 10^1÷2-1÷4= 10^2-1÷4= 10^1÷4
