Answer:
24. 40 minutes approximately
25. 8 days
Step-by-step explanation:
24. 40 minutes
Anna: 1 hour
Peter: 3 hours
Maria: 6 hours
A way to solve this kind of question is to think about how much they can perform given the same amount of time.
Anna: 1 hour x 6: 6 hours (In 6 hours Anna can clean 6 houses)
Peter: 3 hours x 2 6 hours (In 6 hours Peter can clean 2 houses)
Maria: 6 hours x 1: 6 hours (In 6 hours Peter can clean 1 house)
Working together they can clean the house 9 times faster.
It is 0.66 hours, or approximately 40 minutes
25. 8 days

Step-by-step explanation:
1) 3 x 6 x 3 = 54
1 x 2 x 3 = 6
54 + 6 = 60
2) 3 x 6 x 7 = 126
2 x 7 x 4 = 56
126 + 56 = 182
3) 3 x 4 x 2 = 24
9 x 4 x 12 = 432
24 + 432 = 456

Answer:
Question 9: slope= 4
Question 10: 10x+5y = -25
Step-by-step explanation:
For question 9, since it is a linear function, you can think of it as y=mx+b. "m" is the slope value. In your instance, m=4 so the slope is 4. For question 10, you need to reorder it into y=mx+b by moving the -25 to the left side and moving the 5y to the right side. After you do this, you should get 10x+25=-5y. Then divide both sides by -5 to get -2x-5=y. Since m is a negative value, the function has a negative slope. Since the "b" value is the y-intercept and this case it's -5, the y-intercept of the equation is -5.

If an event is likely to occur, which of the following best describes the probability that the event will occur?
A) The probability is between 0 and 1/4
B) The probability is between 1/4 and 1/2
C) The probability isn’t between 1/2 and 3/4
D) The probability is between 3/4 and 1
Answer:
C bc I believe u made a spelling error if not, D
Step-by-step explanation:
closer to 1 = more likeliness
If an event is likely to occur, the probability that the event will occur is between 3/4 and 1.
What is the probability?
Probability determines how likely it is that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
If the probability lies between 0 and 1/5, it is likely that the event would not occur. If the probability lies between 1/5 and 1, it is likely that the event would occur.

Answer:
216 ft²
Step-by-step explanation:
For this question, first find the area of the outsides of the square walls.
Since the cube has side lengths of 6, we can simply find the area of each wall. Remember, for a square, A = s².
A = 6²
A = 36. This is the area for each side of the wall. Since she is painting 4 walls, we can multiply this by 4.
36 ×4 = 144.
To find the area of the ceiling, we will need to use the formula for the area of a triangle : A = 1/2(bh). The base in the figure would be 6, and the height is also 6.
A = 1/2(6 ·6)
A = 1/2 (36)
A = 18. Therefore, each part of the ceiling is 18. Since the base is a square shape, there are 4 triangles that make up the ceiling. Multiply this by 4, giving you:
18 × 4 = 72.
Add the two areas from the walls and the ceiling:
144 + 72 = 216 ft²
Answer:
Ok, so i got 216

f(1)=-3(1)+1 = -2
For x=0 substituting in g(x) the value of x
g(0)=3^(0) =1
Finally, we have to find for what value of x the function f(x) gives -8
f(x) = -8

angle 1 and 3, and angle 2 and 4
Step-by-step explanation:
Answer:
1 and 3 AND 2 and 4
Step-by-step explanation:
Supplementary angles are angles that add up to 180, therefore we can assume that any angles that make a straight line together are supplementary. 1 and 4 do not make a straight line. 2 and 3 do not either. So we have to assume that the answer is either 1 and 3 or 2 and 4. Not sure whether you want one or two answers

the triple of the area of a square is 1587 m2 What is the side of the square?
Answer:
23 m
Step-by-step explanation:
Given that triple the area = 1587 m² , then
area = 1587 ÷ 3 = 529 m²
The area of a square = s² ( s is the measure of the side ), thus
s² = 529 ( take the square root of both sides )
s = [tex]\sqrt{529}[/tex] = 23 m

Which number produces a rational number when added to 1/3
Answer:
[tex]0.22[/tex]
Step-by-step explanation:
[tex]0.22 =22/100[/tex]
0.22 can be expressed as a fraction. Therefore, it is a rational number.
1/3 is a raional number.
[tex]1/3+22/100=83/150[/tex]
To produce a rational number we add 0.22 to 1/3. So, option C. is the right option.
What are rational and irrational numbers?A rational number is any number of the form p/q, where p, q ∈ Z, q ≠ 0, and p and q have no common factors except 1.
Any number which cannot be expressed in the above form is called an irrational number.
How do we solve the given question?In the question, we are asked to find the number from the given choices, which when added to 1/3, produces a rational number.
We know that adding an irrational number to any number gives an irrational number only. So we simply need to check for the rational number among the given options. Analyzing the options:
A. π: It is an irrational number as it cannot be expressed in the required form of p/q for being a rational number. (We sometimes take π = 22/7 which is a rational form, but it is not the actual value of π).B. 5.38516480...: It is an irrational number as it cannot be expressed in the required form of p/q for being a rational number.C. 0.22: It is a rational number as it can be written as 11/50, the required p/q form for being a rational number.D. √10: It is an irrational number as it cannot be expressed in the required form of p/q for being a rational number.∴ We will add 0.22 to 1/3, to produce a rational number. Option C. is the right choice.

Grace is comparing cell phone plans. A prepaid phone plan costs $0.20 per minute and has no monthly fee. A contracted phone plan costs $50 per month and $0.02 per minute. How will the graphs of the monthy costs of the two cell phone plans compare where x represents minutes purchased in a month? The prepaid phone plan will have a steeper line and lower y-intercept. The contracted phone plan will have the same steepness and a higher y-intercept. The prepaid phone plan will have a less steep line and the same y-intercept. The contracted phone plan will have a steeper line and same y-intercept.
Answer: A; The prepaid phone plan will have a steeper line and lower y-intercept.
"The prepaid phone plan, whose cost is $0.20 per minute, will means the usage increases as time increases means that this will have a steeper line and lower y-intercept since it has no monthly fee, Contracted phone plan, whose fee is still $0.02 would have a less steep line and a higher y-intercept because the plan requires monthly fee of $50."

A. The prepaid phone plan will have a steeper line and lower y-intercept.
What are given here ?Grace is comparing plans of cell phone.
A prepaid phone plan costs $0.20 per minute and has no monthly fee.
A contracted phone plan costs $50 per month and $0.20 per minute
What will be the type of graph ?Time increases as usage of the prepaid phone increases, which cost $0.20 per minute. So, the line will be steeper. There is no monthly plan in prepaid phone, so lower y-intercept seen in the graph.
The cost of contracted phone is $0.20 per minute, so the line is less steeper. Again, contracted phone has monthly plan of $50 per month, so the y intercept will be higher.
