A car wash has two employees on duty.
Employee I can finish washing a car in 30 minutes.
Employee 2 can finish washing a car in 20 minutes.
.
How long will it take the tiro employees to wash a car together?
Answers
Answer:
60 minutes
Step-by-step explanation:
Given that Employee I can finish washing a car in 30 minutes. and
employee 2 can finish washing a car in 20 minutes.
Assuming that both will wath the car together after n minutes.
So, n must be the integral multiple of 30 as well as 20.
For niminum value of n, n must be the lowest common factor of 30 and 20.
[tex]\Rightarrow n = LCM(30,20) \\\\\Rightarrow n = 60.[/tex]
Hence, after 60 minutes, they will wash a care togethre.

Step-by-step explanation:
Since the competitor charges $35 per hour PLUS 42(individually), it is 35h+42.
Suzzette's charges should be NO MORE than the competitor, so it could include the SAME amount too. So S(suzzette) is lesser than Or equal to 35h+42.
The answer is C, S≤35h+42

What is the x-intercept of the line 7x - 4y = 28
Answers
Answer:
(0, 4 )
Step-by-step explanation:
To find the x- intercept, let y = 0 in the equation and solve for x, that is
7x - 4(0) = 28, that is
7x = 28 ( divide both sides by 7 )
x = 4 ← x- intercept ⇒ (0, 4 ) as an ordered pair

. Volunteer drivers are needed to bring 80 students to the championship baseball game. Drivers either have cars, which can seat 4 students, or vans, which can seat 6 students. The equation 4c+6v=80 describes the relationship between the number of cars, c, and number of vans, v, that can transport exactly 80 students.
Select all statements that are true about the situation.
If 12 cars go, then 2 vans are needed.
c=14 and v=4 are a pair of solutions to the equation.
If 6 cars go and 11 vans go, there will be extra space.
10 cars and 8 vans isn’t enough to transport all the students.
If 20 cars go, no vans are needed.
8 vans and 8 cars are numbers that meet the constraints in this situation.
Answers
Answer:
3v +2c=32 students
Step-by-step explanation:
Answer:ALL OF THESE ARE TRUE
c=14 and v=4 are a pair of solutions to the equation.
If 20 cars go, no vans are needed.
8 vans and 8 cars are numbers that meet the constraints in this situation.
Step-by-step explanation:
1. If 12 cars go, then 2 vans are needed.(4)(12)+(6)(2) = 80
60≠80
False2.c=14 and v=4 are a pair of solutions to the equation.(4)(14)+(6)(4) = 80
80=80
True
3.If 6 cars go and 11 vans go, there will be extra space.(4)(6)+(6)(11) = 80
90≠80
False
4. 10 cars and 8 vans isn’t enough to transport all the students.(4)(10)+(6)(8) = 80
88≠80
False and is wrong because it would leave extra space
5. If 20 cars go, no vans are needed.(4)(20)+(6)(0) = 80
80=80
True
6. 8 vans and 8 cars are numbers that meet the constraints in this situation.(4)(8)+(6)(8) = 80
80=80
True

Answers
Answer:
y=x
Step-by-step explanation:
Answer:
D. y = -6
Step-by-step explanation:
You can graph each line to see which one is horizontal since the y-axis is vertical. This would make the lines perpendicular since when a vertical and horizontal line meet, they form a 90-degree angle, which is by definition what perpendicular means.

84.7 units²118.125 in³Step-by-step explanation:
The surface area of the triangular prism is the sum of its base areas and the lateral area. The total area of the two triangular bases is ...
A = bh = 7(6.1) = 42.7 . . . square units
The lateral area is the product of the perimeter of the base and the length of the prism. The height given for the prism is consistent with it having triangular bases that are equilateral triangles. That is, the unmarked dimension is likely 7 units, so the perimeter is ...
P = 7+7+7 = 21
and the lateral surface area is ...
LA = PL = 21·2 = 42
Then the total surface area of the prism is ...
total area = A + LA = 42.7 +42 = 84.7 . . . square units
__
The volume of a rectangular prism is given by ...
V = Bh
where B is the area of the base, and h is the height. Your prism has a volume of ...
V = (26.25 in²)(4.5 in) = 118.125 in³

Answers
Explanation:
For number one you could use the slope formula y2-y1/x2-x1, or you could simply just view it from the table that every second that’s passes the distance goes up another 75 meters. This means it would be 75 meters per second.
For the second one it’s a positive correlation that’s related meaning at every whole second (1,2,3...) the line will pass through it, so all you have to do is look at the left and see how much it’s going up by because we know it’s going up by the same amount each time.

Ashley's older brother, Jamaal, is planning to ride his bicycle from Los Angeles to Washington D.C., a distance of 2,668 miles, in two months. Jamaal has decided that he will ride for three days and then rest on the fourth day. If he maintains this plan, and rides on 45 of the 60 days, what is the minimum number of miles that Jamaal must ride each day with his new plan?
Answers
Answer:
60 miles
Step-by-step explanation:
This means the number of days he will ride is
45 days
Hence, the minimum number of miles that Jamaal must ride each day with his new plan is calculated as:
Total number of miles/Number of days
= 2668 miles /45 days
= 59.288888889 miles
Approximately to the nearest whole number = 60 miles
Hence, the minimum number of miles Jamal must ride each day is 60 miles

Answer: 58°.
Step-by-step explanation: From what is given, we see that the other three angles are 122°, 90°, and 90°. Since we know that the sum of the interior angles of a quadrilateral adds up to 360°, we just add up 122, 90, and 90 and subtract the sum from 360°. 122 + 90 + 90 = 302. 360 - 302 = 58. Thus, the answer is 58°.

Answers
Given:
The equation of line is
[tex]7x-5=4y-6[/tex]
To find:
The x and y-intercept of the given line.
Solution:
We have,
[tex]7x-5=4y-6[/tex]
Putting x=0, we get
[tex]7(0)-5=4y-6[/tex]
Add 6 on both sides.
[tex]0-5+6=4y[/tex]
[tex]1=4y[/tex]
Divide both sides by 4.
[tex]\dfrac{1}{4}=y[/tex]
So, the y-intercept is [tex]\left(0,\dfrac{1}{4}\right)[/tex].
Putting y=0 in given equation, we get
[tex]7x-5=4(0)-6[/tex]
Add 5 on both sides.
[tex]7x=-6+5[/tex]
[tex]7x=-1[/tex]
Divide both sides by 7.
[tex]x=\dfrac{-1}{7}[/tex]
So, the x-intercept is [tex]\left(-\dfrac{1}{7},0\right)[/tex].
Answer:
x intercept: (-1/7 , 0)
y intercept: (0, 1/4)
