30 times 0 equals 0
0 is 30 less than 30
What is the value of x?
Enter your answer in the box.
Answer:
35
Step-by-step explanation:
Since all the angles are the same in this triangle, all the sides should be the same too.
Hence, 3x - 5 = 4x - 30
5 + -1x = -30
-1x = -35
x = 35
Hope this helped!
Answer:
Considering the fact that this is an equilateral triangle, x would equal 25
Step-by-step explanation:
since in an equilateral triangle all sides are equal, just pick 2 and solve for x
3x-5=2x+20
3x-2x=20+5
x=25
to check work,
4(25)-30=70
3(25)-5=70
2(25)+20=70
Many professional schools require applicants to take a standardized test.
Suppose that 1000 students take such a test. Several weeks after the test,
Pete receives his score report: he got a 63, which placed him at the 73rd
percentile. This means that... *
Pete scored less than about 73% of the test takers.
Pete scored less than about 63% of the test takers.
Pete scored more than about 63% of the test takers,
Pete scored more than about 73% of the test takers,
Pete's score was below the median.
Answer:
if pete placed in the 73rd percentile, this means that his score was better than 73% of the other test takers, so the fourth option: he scored more than about 73% of the test takers
Step-by-step explanation:
hope this helps :)
The meaning is Pete scored more than about 73% of the test takers.
What is data?Data is information that has been translated into a form that is efficient for movement or processing.
Given situation:
Pete receives his score report: he got a 63, which placed him at the 73rd
percentile.
Percentile is a comparison score between a particular score and the scores of the rest of a group.
So, 73 percentile shows he had done better then 73% of people.
Hence, Pete scored more than about 73% of the test takers.

A new sidewalk will be 4 feet wide, 240 feet long, and filled to a depth of 9 inches (0.75 foot) with concrete. How many cubic yards of concrete are needed?
Answer: The number of cubic yards of concrete that are needed is 720.
Step-by-step explanation: The same formula for this type of shape stays the same: l*w*(h or d).
240 * 4 = 960
960 * 0.75 = 720
The amount of cubic yard of concrete needed is about 720 cubic foot
How to calculate the volume of box?The formula for calculating the volume of the concrete is expressed as:
V = lwh
l is the length =240feet
w is the width = 4 feet
h is the depth = 0.75foot'
Determine the volume
V = 240 * 4 * 0.75
V = 720 cubic feet
Hence the amount of cubic yard of concrete needed is about 720 cubic foot

It is known that a laptop company's average production is given by P(t) = (150t) / (3t+20), where
t is the time (in days). How many days will it take the company to produce 30 laptops?
Answer:
10 daysStep-by-step explanation:
Step one:
given that the expression for the company's average production is
[tex]P(t) = (150t) / (3t+20)[/tex]
Required:
t, when P=30
Step two:
substituting we have
30=150t/3t+20
cross multiply we have
30(3t+20)=150t
90t+600=150t
collect like terms
600=150t-90t
600=60t
divide through by 60
t=600/60
t=10 days
it will take the company 10 days

Answer: 1
Step-by-step explanation: Do math
find the slope of the line passing through (4,-6) (7,2)
Answer:
8 over 3
Step-by-step explanation:
Use
Y2 - y1 over x2 - x1 slop formula
Answer:
the slope in fraction form is 8/3, in integer form is 8.
Step-by-step explanation:
use the x coordinates for the run and the y coordinates for the rise. To find the rise you use the y coordinates -6 and 2, and think about how many spaces away they are on the coordinate plane by adding them both like they are positive. 6 + 2 = 8. To find the run, subtract 7 from 4 which equals 3. So, there you have the rise over run = 8/3 or in integer form, 8.

Please help 15 points available! What is the equation of the line that is perpendicular to y - 3 x = 2 and that passes through (6,1)?
y = 1/3x - 1
y = 1/3x + 3
y = -1/3x + 3
y = -1/3x - 1
Answer:
C) y = -1/3x + 3
Step-by-step explanation:
y - 3x = 2
+ 3x + 3x
y = 3x + 2
find the reciprocal of the slope (3) which is -1/3 so -1/3 will be the slope for the perpendicular line
y = (-1/3)x + b
now find the y-intercept (b)
(6,1) x = 6 y = 1
y = (-1/3)x + b
1 = (-1/3)6 + b
1 = -2 + b
+2 +2
3 = b
y = (-1/3)x + 3
If you travel 2.2 miles in 30 minutes. How many miles did you travel in 12 minutes?
Let m = miles traveled in 12 minutes.
2.2/m = 30/12
Cross-multiply here.
30m = (2.2)(12)
30m = 26.4
m = 26.4 ÷ 30
m = 0.88
In 12 minutes, 0.88 miles is traveled.

The 8th grade class sold snacks at lunch to earn money for a field trip. They sold 30 items this week. For each snack type, what percentage of all snacks sold were of that type? Round to the nearest hundredth if necessary.
Answer:
Step-by-step explanation:
Total number of snacks sold by 8th grade class = 30
Percentage of a particular snack sold = [tex]\frac{\text{Number of particular snack sold}}{\text{Total number of all snacks sold}} \times 100[/tex]
Percentage of cookies sols = [tex]\frac{6}{30}\times 100[/tex] = 20%
Percentage of cheese sticks sold = [tex]\frac{8}{30}\times 100[/tex]
= 26.67%
Percentage of chips sold = [tex]\frac{12}{30}\times 100[/tex]
= 40%
Percentage of water sold = [tex]\frac{4}{30}\times 100[/tex]
= 13.33%
What is the constant
rate of change?
y = 5 – 17x
Answer:
-17
Step-by-step explanation:
The constant rate of change of a line is always the SLOPE. In the equation
y = mx + b, m represents the constant rate of change.
The constant rate of change from this equation is -17 because it's the slope.
