Answer:
35
Step-by-step explanation:
So, lets go over what we know.
One side length is 28.
The other side length is 21.
The missing hypotenuse(longest length) is x.
We can use the pythagreons theorm to find x:
A^2+B^2=C^2. Remember that the two smaller side lengths are A and B, while the longest side length(in this case x) is C.
Plugging in our values:
28^2+21^2=x^2
Distrubute the ^2:
784+441=x^2
Combine the two side lengths:
1225=x^2
Now square root both sides to get x^2 alone(as x)
35=x
So our missing side length, x, is 35!
Hope this helps! :D

A teacher gave a 5 question multiple choice quiz. Each question had 4 choices to select from. If the student completely guessed on every problem, what is the probability that they will have 2 or less correct answers? (CDF)
Answer:
Each question has only one correct answer and the student is equally likely to choose any of the four choices.
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

a school has 60 girls and 90 boys. the ratio of girls to boys
Answer:
60:90
Step-by-step explanation:
The ratio of girls (G) to boys (B) is 2 : 3.
Let the girls be represented by G.Let the boys be represented by B.Given the following data:
Number of girls = 60 girlsNumber of girls = 90 boysIn this exercise, you're required to find the ratio of girls (G) to boys (B). In order to do this, we would divide the two values to the least.
[tex]G : B = 60 : 90[/tex]
Dividing both sides by 30, we have;
[tex]G : B = \frac{60}{30} : \frac{90}{30} \\\\G : B = 2 : 3[/tex]
Therefore, the ratio of girls (G) to boys (B) is 2 : 3.

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

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 find the slope you use rise over run to get 2. to check to see the correct equation replace x with any of the x values in the chart and if you get the same y values as the chart then your equation is correct.
idhi has cut out a semi-circular piece from a plastic sheet and divided it into 8 equal parts as shown: She wants to use this to measure angles. Which of the following angles will she be able to measure accurately using this semi-circular piece?
a. 30⁰
b. 45⁰
c. 60⁰
d. 100⁰
Answer:
[tex]c)\ 45^\circ[/tex]
Step-by-step explanation:
Given
A semicircle divided into 8 parts
Required
Angle that can be measured with the piece
First, we calculate the minimum angle that can be calculated.
[tex]\theta =\frac{Semi\ circle}{8}[/tex]
[tex]Semicircle = 180^\circ[/tex]
So, we have:
[tex]\theta =\frac{180^\circ}{8}[/tex]
[tex]\theta =22.5^\circ[/tex]
This implies that all angles that can be measured using the piece must be a multiple of 22.5 not greater than 180 degrees (i.e. not greater than the semicircle)
So, we have:
[tex]\theta =22.5^\circ,\ 45^\circ,\ 67.5^\circ,\ 90^\circ,\ 112.5^\circ,\ 135^\circ,\ 157.5^\circ,\ 180^\circ[/tex]
From the list of options, only 45 degrees appear in the possible values of [tex]\theta[/tex]
Hence:
[tex]\theta = 45^\circ[/tex]

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°

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.
