Which statements about this triangle are true?
Select all correct answers.
The third angle measures 50°
The third angle measures 90°

The third angle measures 50° and all sides have different lengths.
What is a triangle?A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled.
The sum of angles in a triangle is 180 degrees.
A triangle with angle measures of 100° and 30°, let x represent the third angle, hence:
x + 100 + 30 = 180° (sum of angles in a triangle)
x = 50°
Also, all sides have different lengths since all the angles are different.

Below is a diagram of a rabbit tunnel in the shape of a triangular prism.
What is the volume of the tunnel?
Answer: 412.5cm cubed
Step-by-step explanation:
Volume of a prism: area of base ( in this case it’s the triangle) times the height
First: half x 90 x 120 = 165
Then times the height
So, 164 x 2.5 = 412.5
The volume of the given pyramid will be 1.35m³.
What is a pyramid?
Design or construction with a base that is a polygon and sides that are three or more triangles that come together at the top.
A pyramid is a 3D shape where 3 triangle comes and meet in such a way that the base side creates a triangle.
The volume of a pyramid is given by
Volume = (1/3)base²×height.
Volume = area of cross-section × length
Given,
Area of cross-section = area of the base (triangle)
Since the area of the triangle = (1/2)base×height
So,
Area of cross-section = (1/2)1.20×0.90 = 0.54 m²
So,
Volume of pyramid = 0.54 × 2.5 = 1.35 m³.
Hence " The volume of the given pyramid will be 1.35m³".

Step-by-step explanation:
A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.761 b=20.501 r^2=0.643204 r=0.802 Use this to predict the number of situps a person who watches 2 hours of TV can do ( to one decimal place )
Answer:
The number of situps is approximately 19
Step-by-step explanation:
Regression Line
A regression line is a line that best fits any given dataset in terms of having the smallest overall distance from the line to the points.
Regression lines are useful to forecast the behavior of the dependent variable.
We are given the statistics related to determining if there is a relationship between hours of TV watched per day (x) and the number of situps a person can do (y).
The line is given as follows:
y=-0.761x+20.501
The rest of the parameters can only be used as a reference to evaluate how good the line approaches the dataset.
Now use the line to predict the number of situps a person who watches x=2 hours of TV can do:
y=-0.761*2+20.501
y=19
The number of situps is approximately 19

Which number below is a prime number?
a
O A. 76
B. 79
C. 100
D. 66
Answer:
79
Step-by-step explanation:
↓ Define Prime number ↓
Prime number ⇒ A positive integer that has no positive integer divisors other than 1 and itself. To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number.
Solve:
76 is not a prime number. The number 76 is divisible by 1, 2, 4, 19, 38, 76.
79 is a prime number. The number 79 is divisible only by 1 and the number itself.
100 is not a prime number. The number 100 is divisible by 1, 2, 4, 5, 10, 20, 25, 50, 100.
66 is not a prime number. The number 66 is divisible by 1, 2, 3, 6, 11, 22, 33, 66.
Hence 79 is a prime number

You have a credit card that has a balance of $3850 at an APR of 13.99%. You plan to pay $300 each month in an effort to clear the debt quickly. How many months will it take you to pay off the balance?
Answer:
about 14 months
Step-by-step explanation:
Questions regarding loan payments, values, interest amounts, number of payments, and so on, are conveniently answered by the financial formulas available in many apps, calculators, and spreadsheets. Here, we want to solve for the number of payments.
__
The time-value-of-money app on a TI-84 calculator tells us the number of monthly payments is 13.98. It will take about 14 months to pay off the credit card balance.
__
Alternate solutions
You can also use a graphing calculator to find the time value needed in the amortization formula that corresponds to a monthly payment amount of $300 on a loan of $3850 at 13.99% interest compounded 12 times per year. This is shown in the second attachment.
The algebraic solution is a little messy, and involves logarithms, but you can solve it that way, too.
A = P(r/n)/(1 -(1 +r/n)^(-nt))
gives the monthly payment A on a loan of principal P at annual rate r compounded n times per year for t years. We want to find the value of nt for P=3850, A=300, r=0.1399, n=12.
Putting in the numbers, we get ...
300 = 3850(0.1399/12)/(1 -(1 +0.1399/12)^(-nt))
(1.011658333...)^(-nt) = 0.8503847222... . . . . isolate nt term
nt = -log(0.8503857222...)/log(1.011658333...) ≈ 13.982213...

Zach throws a ball upward so that it follows the equation
y= 16x^2 + 64 +5 where y is the height of the ball and x is time.
How many seconds will it take for the ball to hit the ground?
Hey there!
=> y= 16x^2 + 64 +5
Let's obtain a formula for x
=> y= 16x^2 + 64 +5
=> y=16x^2+69
=> y - 69 = 16x^2
=> y - 69/16 = x^2
=> y - 4.3125 = x^2
=> x = √y - 4.3125
=> x = y - 2.08
