Darnell is trying to understand the Pythagorean Theorem by drawing a few triangles. He found that 1² + 1² = (√2)² is accurate. Which statement is true about Darnell’s triangle?
A. The triangle is not a right triangle because the lengths of its sides measure the same.
B. The triangle is not a right triangle because the hypotenuse is shorter that the lengths of its sides.
C. The triangle is a right triangle, the lengths of its sides are 1 and √2 with a hypotenuse of 1.
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
PLEASE HELP ASAP!!!!
Answers
Answer:
D. The triangle is a right triangle, the lengths of its sides are 1 and 1 with a hypotenuse of √2.
Step-by-step explanation:
The Pythagorean Theorem is modeled by a² + b² = c².
c represents the hypotenuse and a and b represent the other two sides.
The Pythagorean Theorem can only be applied to right triangles.

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 35 problems. Each problem is worth either 5 points or 2 points. How can you set up a system of equations to find how many problems of each point value are on the test?
Let x = the number of questions worth 5 points.
Let y = the number of questions worth 2 points.
Answers
Answer:
Step-by-step explanation:
5x+2y=100
x+y=35
x=10
y=25
y - the number of 2 points worth problems
The test has 29 problems.
x+y=29
The test is worth 100 points.
5x+2y=100
The system of equations:
x+y=29
5x+2y=100
The solution:
-2x-2y=-58. | x (-2)
5x+2y=100
divided by
3x=42. (divided by 3)
x=14
14+y=29
y=15

What is the value of the mean absolute deviation of the weight of the bags, and what does it represent about the weight of a bag?
A) 1.8 pounds; on average, weight of a bag varies 1.8 pounds from the mean of 7 pounds
B) 1.3 pounds; on average, weight of a bag varies 1.3 pounds from the mean of 7 pounds
C) 1.3 pounds; the weight of 50% of the bags is greater than 1.3 pounds
D) 1.8 pounds; the weight of 50% of the bags is greater than 1.8 pounds
Answers
Answer:
B
Step-by-step explanation:
Take all of the numbers and add them up and then divide by the number of numbers (In this case 6). This is the average which is 7. Then see how far each number is from 7 and take the average of those. This gives you 1.3. So, the answer is B.

Step-by-step explanation:
i hope this helps, the wording is a little confusing to me tho
Answer:
1. 1/12
2. 4/15
Step-by-step explanation:
1.
3/4 - 2/3
first, you need to set both of the denominators to the same digit by multiplying both the numerator and denominator by the same number
same number meaning the denominator of the other fraction
multiply 3/4 by 3/3
= 9/12 (3x3 and 4x3)
multiply 2/3 by 4/4
= 8/12 (2x4 and 3x4)
9/12-8/12= 1/12
How much of the whole pizza does he take for lunch?
answer: 1/12 of the pizza
2.
(same thing)
2/3 - 2/5
10/15 - 6/15= 4/15
How much of the whole cake did she eat after school?
answer: she ate 4/15 of the cake

6x + 12 = 10x − 4 1. Solve for x using two different methods
Answers
Answer:
x=53/4 or 4x=53
Step-by-step explanation:
First move the variable to the left-hand side and change its sign.
6x+12-10x=-41 to 6x-10x=-41-12
Then collect the like terms
6x-10x=-41-12 to -4x=-41-12 which equals to -4x=-53
Now you divide both sides of the equation by -4
-4x=-53 to x=53 over 4 then if you want you divide which gives you x=13.25
Second way:
Kind of the same thing as the first one
Move the variable to the left-hand side and change its sign
6x+12=10x-41 to 6x=12-10x=-41
Then you collect the like terms
6x-10x=-41-12 to -4x=-41-12
Now you multiply both sides of the equation by -1
-4x=-53 to 4x=53

Bridgette had a whole pie. She ate 1/4 of the pie for a snack and ate another 25% of the pie for dessert. What fraction of the pie did Bridgette NOT eat?
Answers
Answer:
1/2
Step-by-step explanation:
Bridgette ate 1/4 of the pie, and 25% of the pie.
25% is converted to 1/4.
1/4 + 1/4 = 1/2.
1 - 1/2 = 1/2.
Bridge did NOT eat 1/2 of the pie.
Answer:
1/2
Step-by-step explanation:
She ate 50%
1/4 is the same as 25%
So 25% + 25% is 50%.
100%-50% is 50%
50% as a fraction is 1/2
