Answer:
A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636
as a fraction it would be 36/99, divide both numbers by 9 to get 4/11
B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666
as a fraction that would be 33/90 , divide both by 3 to get 11/30
C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

Three numbers are in the ratio 5 :3 : 2. If the sum of their squares is 5472, find the three numbers
Answer:
60 36 24
Step-by-step explanation:
5 3 2
25x +9x + 4x = 5472
38x = 5472
x = 144
25(144) = 3,600 9(144) = 1,296 4(144) = 576
60² = 3,600 36²= 1,296 24² = 576
3,600 + 1,296+576 = 5,472
What is 45% of 40=
How to solve percentages.
Answer:
18
Step-by-step explanation:
Usually in math problems, the word "of" means to multiply. So this question would be 45% times 40. It would be easier to calculate this by turning 45% into a fraction, which is 45/100. Then, we solve.
45/100 times 40
40(45)/100
1800/100
=18

Answer:
C = 25
a = 10.72
b = 11.83
Step-by-step explanation:
The easiest thing to solve for right now is C- all angles in a triangle add up to 180 degrees. So we can subtract 65 and 90 from 180 to get the measure of angle C, 25 degrees.
Then we can use trigonometric functions: SOH CAH TOA
sinC = opposite / hypotenuse
sin25 = 5 /hyp
5/sin25 = hyp
hyp (aka b) = 11.83
cosC = adjacent / hypotenus
cos25 = a/11.83
11.83*cos25 = a
a = 10.72
C = 25
a = 10.72
b = 11.83

Your answer
Answer:
C = 81.69 ft
Step-by-step explanation:
Given the following data;
Diameter = 26 ft
To find the circumference of a circle;
Mathematically, the circumference of a circle is given by the formula;
Circumference of circle, C = πd
Where;
d represents the diameter of the circle.
Substituting into the formula, we have;
C = 3.142 * 26
C = 81.69 ft
Out of a group of 120 students that were surveyed about winter sports 28 said they ski 53 said they snowboard Sixteen of the students who said they ski said the also snowboard. If a student is chosen at random P ( snowboard I ski)
Answer:
P ( snowboard I ski) = 0.5714
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Ski
Event B: Snowboard.
28 out of 120 students ski:
This means that [tex]P(A) = \frac{28}{120} = 0.2333[/tex]
16 out of 120 do both:
This means that [tex]P(A \cap B) = \frac{16}{120} = 0.1333[/tex]
P ( snowboard I ski)
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1333}{0.2333} = 0.5714[/tex]
So
P ( snowboard I ski) = 0.5714
Anne works in a factory she recieves a salary of $8 per hour and piecework pay of 12 cents per unit produced
Answer: See explanation
Step-by-step explanation:
a. What was her piece work pay?
Anne's piecework pay = 12 cents per unit produced
Number of units produced = 755
Anne's Piecework pay = $0.12 × 755 = $90.60
b. What was her total hourly pay for the week?
Anne's hourly pay = $8 pee hour
Number of hours worked = 38
Total hourly pay = 38 × $8 = $304
c. What was her total pay for the week?
This will be:
= $90.60 + $304
= $394.60

Find the area of the composite figure shown below.
A. 12 cm2
B. 36 cm2
C. 24 cm2
D. 18 cm2
Based on the figure below, find the value of x.
Answer:
The value of x = 9.Step-by-step explanation:
The figure shown is represented as a right triangle, which means that the sum of the angles within should add up to 90°. So if we take 32° (one of the angles given) and subtract it from 90°, we should be left with 58°.
This means that the value of the equation that contains "x" must equal 58°. Therefore, (6 x 9 + 4)° must equal 58.° Which means that the value of x = 9.

Answer:
C, 108 ft²
Step-by-step explanation:
To solve, we need to find the area of each of the shapes and then add them together.
The top rectangle's area: 8 * 3 = 24
The left triangle: 3 * 4 * 0.5 = 6
The middle rectangle: 8 * 4 = 32
The right triangle: 4 * 3 * 0.5 = 6
The bottom rectangle: 5 * 8 = 40
Add them all together.
24 + 6 + 32 + 6 + 40 = 108 ft²
Thus, the answer is C, 108 ft²

A skateboard ramp has a 158° entry angle. Find the measure of 1
Answer:
B. 68°
Step-by-step explanation:
The interior angles of the right triangle from the figure given are:
<1, right angle (90°), and (180° - 158°)
m<1 + 90° + (180° - 158°) = 180° (sum of triangle)
m<1 + 90° + 22° = 180°
m<1 + 112° = 180°
m<1 + 112° - 112° = 180° - 112°
m<1 = 68°
Answer: 68

y = -45x + 13
Step-by-step explanation:
The equation is *** y = [tex]-5x^{2}[/tex] - 20x +13 ***
First: you have to look at [tex]-5x^{2}[/tex] which would equal -25x
Second: you have take the -25x and put into the equation... y = -25x - 20x +13
Third: You have subtract -25x - 20x which equals -45x
Lastly: Now you have y = -45x + 13 and since 13 does NOT have a variable like -45x does, you then know that you have finished the equation
