If one angle of an equilateral triangle was 60 degrees, then what is the angle of the other two?
Students at a local school can join one club. The chart below shows how many students are in each club. What percentage of the total number of students are in the outdoor club? (3 points - 2 pts for each correct answer, 1 pts total for showing work) Number of Students Percent of Students Club Photography Coding 32 16% 64 32% Outdoor 40 Gaming 64 Show your work below: =
Answer:
20%
Step-by-step explanation:
If you already know that 64 students equals 32% you can fill the gaming club in for 32%. Since 100% is the goal you can add 32+32+16 to get 80 and subtract that from 100 to get the remaining percent.
Find the measure of the angle. (final)
Answer:
39˚
Step-by-step explanation:
The whole thing is a right angle, and we know that because of the square thing at the top.
These two angles are complementary, so we can subtract 51 from 90.
90-51=39˚

Choose the equation below that represents the line that passes through the point (-2, -1) and has a slope of 5. (5 points)
O. y- 1 = 5(x - 2)
O. y + 1 = 5(x + 2)
O. y + 2 = 5(x + 1)
O. y-2-5(x - 1)
Step-by-step explanation:
That's the solution;
Final answer; y + 1 = 5 ( x + 2 )
If y varies directly as x, and x =9 when y =15, Find y when x =21
y = x
15 = 9
y = 21
9y = 315
y = 315/9
y = 35
Answer:
35
Step-by-step explanation:
y is propotional to x, means, if x changes, y changes.
Considering, y depends on x only. Introduce a constant.
y = kx
When x = 9, y = 15,
=> 15 = k(9) => 5/3 = k
When x = 21, note that k is constant.
=> y = kx = (5/3)*21
= 35

Write the equation of the line that passes through the points (-5,1) and (5,8). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (8 - 1) / (5 - (-5))
m = 7/10
y-intercept using slope above and anyone of given point. Let's use (-5, 1):
y = mx + b
1 = 7/10(-5) + b
1 = -35/10 + b
b = 45/10
b = 9/2
Equation of line:
y = mx + b
y = 7/10x + 9/2
Point slope form:
y - y₁ = m(x - x₁)
y - 1 = 7/10(x - (-5))
y - 1 = 7/10(x + 5)

I need to buy enough white boards for 172 students and there are 25 in a pack when the pack arrives 12 whiteboards are damaged. How many whiteboards are undamaged?
Answer:
There are 163 whiteboards undamaged.
Step-by-step explanation:
So first we know that 12 are damaged and there are 172 students. So first we need to find out how many whiteboards did you buy without knowing there will be 12 damaged. The answer is 7 because there are 25 per pack. And 7 * 25 = 175. You can't buy less because you rather buy extra rather then not enough. Now knowing that, what is 175 - 12 because 12 was damaged.
175 - 12 = 163.
There are 163 whiteboards undamaged.
163 white boards are undamaged

we need 172 whiteboard but one pack consist of 25 whiteboards
⇒ 172/25 = 6.88
≈ 7 pack
Total whiteboard we buy
⇒ 7 × 25 = 175
Out of which 12 whiteboard are damaged
↓ Undamaged whiteboard ↓
→ 175 - 12 = 163 ←
thus, 163 whiteboards are undamaged

Which of the following is a true statement?
3/4>9/12
3/5<4/7
6/7<5/8
5/12>3/8
Can any show me another one simple way to do this.
Answer:
The answer is the last one 5/12 > 3/8
Step-by-step explanation:
Convert the fractions to regular numbers so 5/12 just do 5 ÷ 12 and 3/8 do 3 ÷ 8 whatever side has the arrow opened to means that's should be the bigger number for example 2 > 1 is true because 2 is greater than 1 but 2 < 1 is false
Answer:
5/12>3/8
Step-by-step explanation:
you need a common denominator
you multiply 5/12 by 2 the top and the bottom to get 10/24
then you multiply 3/8 by 3 the top and the bottom to get 9/24
10/24>9/24

The functions (f.g)(x) and (g.s)(x) are illustrations of composite function
The values of the composite functions are:
(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10
How to determine the equation of the composite functionThe equation of the functions are given as:
f(x) = 3x - 8
g(x) = -2x + 5
s(x) = 4x^2 - 9x + 2
.
The composite functions are calculated using:
(fg)(x) = f(x) * g(x)
So, we have:
(f g)(x) = (3x - 8) * (-2x + 5)
Evaluate the product
(fg)(x) = -6x^2 + 15x + 16x - 40
Evaluate the like terms
(fg)(x) = -6x^2 + 31x - 40
Also, we have:
(gs)(x) = g(x) * s(x)
So, we have:
(gs)(x) = (-2x + 5) * (4x^2 - 9x + 2)
Expand
(gs)(x) = -8x^3 + 18x^2 -4x + 20x^2 - 45x + 10
Collect like terms
(gs)(x) = -8x^3 + 18x^2 + 20x^2-4x - 45x + 10
Evaluate the like terms
(gs)(x) = -8x^3 + 38x^2 -49x+ 10
Hence, the values of the composite functions are:
(fg)(x) = -6x^2 + 31x - 40 and (gs)(x) = -8x^3 + 38x^2 -49x+ 10

can anybody explain how to subtract mixed fractions?
Answer:
convert the mixed fractions to improper fractions (where the numerator is greater than or equal to the denominator): multiply the whole number part by the fraction's denominator, add that to the numerator, write the result on top of the denominator.if the denominators are not the same, work out the common denominator and rewrite the fractions with the same denominatorssubtract by subtracting the numerators and writing the result over the denominatorconvert back to mixed fractions by dividing the numerator by the denominator, write down the whole number answer, write down the remainder above the denominator.
Example
[tex]3\frac23-1\frac45[/tex]
convert to improper fractions:
[tex]\dfrac{3 \times 3+2}{3}-\dfrac{1 \times 5+4}{5}=\dfrac{11}{3}-\dfrac{9}{5}[/tex]
common denominator = 3 × 5 = 15, so:
[tex]\dfrac{11}{3}-\dfrac{9}{5}=\dfrac{11\times 5}{3\times 5}-\dfrac{9\times 3}{5\times 3}=\dfrac{55}{15}-\dfrac{27}{15}[/tex]
subtract:
[tex]\dfrac{55}{15}-\dfrac{27}{15}=\dfrac{55-27}{15}=\dfrac{28}{15}[/tex]
convert back to mixed fractions:
[tex]28 \div 15=1 \textsf{ remainder }13=1 \frac{13}{15}[/tex]
To subtract mixed fractions, we must follow the steps:
Convert the mixed fraction to improper fraction.2. Multiply the denominator and the numerator by the LCM of the denominators to make the denominators same. P.S: (If the denominators are the same, you can skip this step).
3. Simplify the fractions. (The denominators do not change).
4. (Optional) Convert the fractions to mixed fraction.
Solving an example:Let's take an example.
⇒ [tex]4 \frac{2}{5} - 3 \frac{3}{8}[/tex]Step-1: Convert the fractions to improper fraction:
⇒ [tex]4 \frac{2}{5} - 3 \frac{3}{8}[/tex]⇒ [tex]\frac{(4)(5) + 2}{5} - \frac{(3)(8) + 3}{8}[/tex]⇒ [tex]\frac{20 + 2}{5} - \frac{24+ 3}{8}[/tex]⇒ [tex]\frac{22}{5} - \frac{27}{8}[/tex]Step-2: Make the denominators same:

a) $24.25
b) $35.50
c) $46.80
d) $50.00
Answer:
C) $46.80
Explanation:
The price of new shoes = $85
The amount paid for the shoes = $ 40
The balance amount for the shoes = $85 - $40 = $ 45
The rate of interest = 8%
The time period = 6 months = 0.5 years
Simple interest:
Simple interest = = $1.8
So, Amount = Principal + Interest
