Step-by-step explanation:
A cleaning company charges x dollars per hour to clean floors and y dollars per hour to clean the rest of the house
-when the company spends 2 hours to clean floors and 3 hours to clean the rest of a house,the total is $84.
-when the company spends 1 hour to clean floors and 4 hours to clean the rest of a house,the total is $87
Which ordered pair represents the hourly charges to clean floor and to clean the rest of the house?
A.(12,20)
B.(15,18)
C.(20,12)
D.(18,15)
Answer:
(15,18)
Step-by-step explanation:
write two equations with the information provided.
2x + 3y = 84
x + 4y = 87
use the property of substitution to answer.
x + 4y = 87, x = 87 - 4y
2(87 - 4y) + 3y = 84
174 - 8y + 3y = 84
174 - 84 = 8y - 3y
90 = 5y
90/5 = y
y = 18
Add the value of Y to an original equation. Solve for X
2x + 3(18) = 84
2x + 54 = 84
2x = 84 - 54
2x = 30
x = 30/2
x = 15
factory makes car batteries. The probability that a battery is defective is 1/14. If 400 batteries are tested, about how many are expected to be defective?
A) 14
B) 371
C) 29
D)35
The required number of defective batteries is 29 out of 400 batteries tested. Option C. is correct.
The probability that a battery is defective is 1/14. The probability that a battery is defective is 1/14. If 400 batteries are tested, how many are expected to be defective s to be determined?
Probability can be defined as the ratio of favorable outcomes to the total number of events. it can be denoted as,
Probability = number of favorable outcomes / total sample space
The probability that a battery is defective given by,
P(D) = 1/14 = 0.072 or 7.2%
400 batteries are tested while multiplying the defective percentage to the number of batteries it gives the defective number of batteries
Number of defective batteries,
= 400 * 7.2%
= 400 * 7.2/100
=≈ 29
Thus, the required number of defective batteries is 29 out of 400 batteries tested. Option C. is correct.

Which of the following side lengths can form a triangle?
23, 28, and 55
24, 24, and 47
15, 30, and 45
8, 17, and 25
Answer: 24, 24, 47
Step-by-step explanation:
In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations.
a + b > c & a + c > b & b + c > a
23 + 28 = 51 which is NOT greater than 55
15 + 30 = 45 which is NOT greater than 45
8 + 17 = 25 which is NOT greater than 25
24 + 24 > 47 & 24 + 47 > 24 & 24 + 24 > 27
all combinations are true so these side lengths can form a triangle
1) Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?
Unit rate (speed) _____
Distance _____
2) Pira drives 825 miles to California. The trip takes 17 hours. He uses 38 gallon of gas on the trip, which costs him $125.
Find his speed
Find his gas mileage
Find the unit price he paid for gas.
Answer:
Step-by-step explanation:
Mr. Anderson drove 168 miles in 3 1/2 hours: d1 = 168 mi
t1 = 3 1/2 hr
t1 = 3.5 hr
v1 = the first rate
v1 = d1/t1
v1 = 168/3.5
v1 = 48 mph
He then drove 2 1/4 hours at a rate of 5 miles an hour faster than the first rate:
t2 = 2 1/4 hr
t2 = 2.25 hr
v2 = v1 + 5
v2 = 48 + 5
v2 = 53 mph
d2 = the distance
d2 = v2*t2
d2 = 53*2.25
d2 = 119.25 mi
during the total time 3 1/2 + 2 1/4 = 5 3/4 hr Mr. Anderson drove:
d1 + d2 = 168 + 119.25 = 287.25 mi.

a sector with a radius of 15 cm has a central angle measure of 8π/5 what is the area of the sector
Answer:
area of the sector = 360π cm²
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case the angle is measured in radiance, hence we will use the second formula
From the question given, radius = 15 cm and angle Ф = 8π/5
area of sector = 1/2 × r² × Ф
=1/2 × 15² × 8π/5
=1/2 ×225 × 8π/5
=360π cm²
area of the sector = 360π cm²
Please, if I get this wrong I fail please help me, it will mean a lot to me
Answer:
x = 58°
Step-by-step explanation:
First, we need to find the green angle on the bottom left of the triangle.
We know that straight lines are supplementary, or equal 180 degrees, so we can say that 114° + a (a variable representing the measure of the angle) = 180°.
Equation:
114 + a = 180
Solve:
114 + a = 180
-114 -114
a = 66
Therefore, the value of the green angle is 66 degrees.
Now, we need to find the value of angle x.
We know that the sum of the angles in a triangle is 180 degrees.
So, 56° + 66° + x = 180°
Equation:
56 + 66 + x = 180
Add:
56 + 66 + x = 180
122 + x = 180
Subtract:
122 + x = 180
-122 -122
x = 58
Therefore, x is 58 degrees.
Answer:
58
Step-by-step explanation:
An exterior angle is equal to the two remote interior angles. It would be easier to understand that just by adding the numbers in an equation.
Exterior angle = 114
Remote interior angles = x and 56
exterior angle = sum of x and 56 which are the two remote interior angles.
x + 56 = 114 Subtract 56 from both sides.
x+56-56=114-56
x = 58

The number in the chart are the math test scores of 10 seventh hrade students.
Which of the following is most affected by the lower score?
A.) the mean and median
B.) the median
C.) the mean
D.) the mode
Answer:
C
Step-by-step explanation:
The mean of a set of values is the average of all of them. The median is just the center most value when you arrange the values in order from least to greatest, or the average of the most central two if there is an even number of values. The mode is simply the value that shows up the most. The single, low outlier does not affect the median and mode almost at all, and only has a large influence on the mean, since it brings down the average. Therefore, the correct answer is choice C. Hope this helps!
Answer:
The mean... the median is in the middle, it won't change, the mode is the most repetitive number and it won't change neither... so the mean will be the most affected.
