a)15 and 18
b)21 and 47
c)64 and 88
Answers
Answer:
hmm i think its A
Step-by-step explanation:
The complete question:
What is the range of values of x for a triangle's third side given side measures
of 8 and 15 for the other two sides?
A) Between 8 and 15
B) Between 7 and 23
C) Less than 7, greater than 23
D) Between 8 and 23
Solution:
The measure of third side will fall Between 8 and 23. So Option D is correct.
What is Triangle Inequality Theorem ?The third side of a triangle must be shorter than the sum of the other two sides and longer than the difference between the other two sides. This is known as the Triangle Inequality Theorem.
Given that,
The triangle,
whose two sides has length,
8 and 23 unit
So, for a triangle with sides of 8 and 15, the third side must satisfy the following inequality:
7 < x < 23
Therefore, the range of possible values for the third side of the triangle is:
D) Between 8 and 23

-9 + 1/4x - 6 - 1/8x
Answers
Answer:
Assuming you want me to simplify your answer, the answer to your question is x/8-15.
Step-by-step explanation:
Simplify each term by combining 1/4 and x, and then combine x and 1/8 to get -9+x/4-6-x/8. Subtract 6 from -9 for x/4-15-x/8. Write x/4 as a fraction with a CD (Common Denominator) by multiplying by 2/2. Write each expression with a CD of 8. Combine the numerators, subract x from x*2 by reordering x and 2 to get 2*x-x/8-15. Then subract x from x to get x/8-15.

Find the probability that when four numbers from 1 to 100, inclusive, are picked at random with no repetitions allowed, either all are odd, all are divisible by 3, or all are divisible by 5.
Answers
Answer:
The probability is;
0.076
Step-by-step explanation:
The count of numbers from 1 to 100 is 100
Let’s find the number of odd numbers
We can use;
a + (n-1)d = T
a is 1, d is 2 and T is 99
Thus;
1 + 2(n-1) = 99
n-1 = (99-1)/2
n-1 = 59
n = 50
So there are 50 odd numbers
Probability of selecting an odd number is 50/100 = 1/2
If all 4 are odd, we have 1/2^4 = 1/16
Let’s get the multiples of 3
we can use
a + (n-1)d = T
a = 3, n = ? , d = 3 and T = 99
So;
3 + 3(n-1) = 99
n-1 = 34
n = 33
So the probability is 33/100
All 4 are divisible will give 33/100^4
Multiples of 5
a + (n-1)d = T
a = 5, n = ? , d = 5 T = 100
5 + (n-1)5 = 100
5(n-1) = 95
n-1 = 19
n = 20
Probability is 20/100 = 1/5
All
four are multiples of 5
1/5^4 = 1/625
So the probability is;
1/16 + 1/625 + 0.01185921
= 0.0625 + 0.0016 + 0.01185921 = 0.07595921

Graph 2 has opposite expressions
Start by calculating the equations of the functions.
From the graphs, we have the following equations
Graph 1: y = -|2x| + 2Graph 2: y= 2x -2 and y= -2x - 2Graph 3: y = 2x - 1 and y = -2x + 1Graph 4: y = -2x + 1 and y = 2x - 1An opposite function is defined by y = f(x) and y = f(-x)
Graph 1 is an absolute value graph.
Check if y = f(x) and y = f(-x) is true for function 2.
We have:
[tex]f(x) = 2x - 2[/tex]
[tex]f(-x) = 2(-x) - 2[/tex]
[tex]f(-x) = -2(x) - 2[/tex]
For graph 2, f(x) and f(-x) are true.
Hence, graph 2 has opposite expressions

Marcus is considering two car rental plans. Plan A can be modeled with the equation C = 30 d , and Plan B can be modeled with the equation C = 25 d + 15 , where C represents the cost in dollars and d represents the number of days a car is rented. Which statement would justify selecting Plan B instead of Plan A?
Answers
Answer: Marcus rents a car for 3 days.
Answer: d. Marcus rents a car for 5 days.
Step-by-step explanation:
If D = the number of days then C=25(5)+15=140(plan b)
C=30(5)=150 (plan a)
Plan b is better because plan b cost less than plan a for 5 days.
