Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.
Determine whether the conclusion is valid. Explain.
You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
A. yes; The sample is representative of the population, selected at random, and large enough to provide accurate data. So, the sample is unbiased and the conclusion is valid.
B. yes; The sample is representative of a specific group, selected based on age, and small enough to provide accurate data. So, the sample is biased and the conclusion is valid.
C. no; The sample is not representative of the population because students who are older have had more opportunities to visit a science museum. So, the sample is biased and the conclusion is not valid.
D. no; The sample is representative of the population, selected at random, and too large. So, the sample is unbiased and the conclusion is not valid

Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?
Answer:
Sally is 23 years old.
Step-by-step explanation:
John's age is completely unknown, so it is known as x
Meanwhile, Sally's age can be represented as 3x+2
The sum of both ages is 30.
So, x+3x+2=30
Combine like terms.
4x+2=30
Subtract 2 from both sides.
4x=28
Divide both sides by 4.
x=7
John is 7 years old.
Sally's age: 3(7)+2=23
Sally is 23 years old.
Rico spins the spinner twice and determines the sums of the spins. Fill in the sample space to determine the possible outcomes. What is the probability that Rico will get a sum less than or equal to 8? A 13\frac{1}{3} 3 1 B 23\frac{2}{3} 3 2 C 89\frac{8}{9} 9 8 D 59\frac{5}{9} 9 5
Answer:
2/3
Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9
|
4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3

Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6
