Answer:
G
Step-by-step explanation:
First off, we know that Trinity is allowed to watch 420 minutes of television a week, which means that her watch time can be=420, cannot be >than 420 minutes, and can be <than 420 minutes. (in other words, her watch time can be equal to or less than 420 minutes) Because of this, we know that our answer choice must have 420≥. So H and J are out of the question.
Also, we know that each show that she watches is 30 minutes long. Because of this, the next part of our answer is going to be 30s. (I will explain this in the comment section of my post because it's getting a little long)
Therefore, the answer is G: 30s≤420
Answer:
G 30s < 420
Step-by-step explanation:
Trinity can watch 420 min of TV, which is "less than or equal to" but not more than 420 min. Therefore your inequality will be < 420
Next part says each show "s" is 30 min long, so you would multiple 30 times s which would be represented as 30s (think: 1 show is 30(1) =30, 2 shows is 30(2) = 60, 10 shows is 30(10) = 300, etc)
So, put together:
30s < 420 (or 30 min multiplied by 's' number of shows has to be less than or equal to 420)

Using the Pythagorean Theorem, fill in the table. [Assume a and b are the lengths of the legs and c is the length of the hypotenuse.]
A B C
25 60
[ Select ]
7
[ Select ]
25
[ Select ]
30
34
9 40
[ Select ]
Answer: It would be Second leg = 15
Step-by-step explanation:
From my understanding, you are supposed to find the second leg of the right triangle by Pythagoras theorem.
Hypotenuse: 25
One leg: 20
Second leg: x
Pythagoras theorem: hypotenuse² = adjacent² + opposite²
c² = a² + b²
25² = 20² + b²
b² = 25² - 20²
b² = 625 - 400
b² = 225
b = √225
b = 15
Therefore, the second leg of the right triangle is 15.

The table shows the approximate number of minutes of physical exercise each student in Noah’s class gets per day. Identify any outliers in the data set and explain how they affect the data.
I need an explanation please.
Answer:
120 and 180 minutes have outliers
Step-by-step explanation:
An outlier is a point of data in a data set that is far out from the median in the data set. In this case, almost all of the data points are from 0 minutes of exercise to 60 minutes, except for two that are more than double that.
It could "skew" the data, as if you were to calculate the mean (average), it would be shifted slightly higher by these two outliers.
Hope this helps!
Answer:
120 and 180 have outliners

Answer:
B
Step-by-step explanation:
-the base angles are 34, so the total value of both base angles is 68
-an isosceles triangle is equal to 180
-subtract 68 from 180 for the answer, so the equation is 68+x=180

Answer:
a. 28
b. 6.5
c. 30
Step-by-step explanation:
1% = 80÷100
35% = 0.8×35
1% = 0.65
0.65 × 10 = 6.5
1% = 0.5
60% = 0.5×60
Answer:
28
6.5
30
another way you can get these answers is by cross multiplying. In order to do that you need to identify the percent, the whole (of), and the part (is). In identifying the whole and the part, look for the word is, and the word of. The number that is associated with is either the part or the whole. (There is 6 out of 80, what is the percentage?) always set the percentage out of a hundred.
So from there we set up the proportion:
ONE
(we don't know the part in any of them)
X/80=35/100 (cross multiply by putting the numbers on top of each other for the fractions)
TWO
X/65=10/100
THREE
X/50=60/100
Hope this helps, have a good day and remember to be tiger fierce!! :) (also, sorry that it is late.)
Miguel bought a table on sale for $266. This price was 65% less than the original price.
What was the original price?
Answer: 409.23
Step-by-step explanation: Step 1: If 65% of a number is 266, then what is 100% of that number? Setup the equation.
266
65% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
65Y = 266 x 100
65Y = 26600
Y = 26600
100 = 409.23
HELP PLEASE
HELP PLEASE HELP PLEASE
Step-by-step explanation/ Answers
because you have 5% possibilities and a total of 100%. You divide
100 by 5 and then you get 20 so that is for question 5
for question 6 it would be 80 because 100 - 20 is 80
for question 7 it will be 40 because 20 + 20 is 40

USE THE SQUARE ROOT PROPERTY!!!!!
the sides of a square are reduced by 2 inches. the new area is 20 square inches. Set up and solve an equation to find the original length of the square
Answer:
Step-by-step explanation:
x = original length of one side
(x-2)² = 20 inches²
x-2 = ±√20 = ±2√5
x = 2±2√5
2-2√5 is an extraneous solution,
so x = 2±2√5 ≈ 6.47 inches
