Step-by-step explanation:
You are subtracting 10a^2 + 6a + 2 from 7a^2 - 8.
You can set it up like the problem shows you, and subtract each term in the second line form a like term in the top line.
7a^2 -8
(-) 10a^2 + 6a + 2
-----------------------------
-3a^2 - 6a - 10
Answer: -3a^2 - 6a - 10

What is the equation in standard form of
the line that passes through the points
(3, 5) and (-7, 2)?
Answer:
3x-10y=-41
Step-by-step explanation:
"standard form of the line" is ax+by=c, where a, b, and c are free coefficients
first, we need to find the slope (m) of the line
that is calculated with the formula (y2-y1)/(x2-x1)
we have the points (3,5) and (-7,2)
label the points:
x1=3
y1=5
x2=-7
y2=2
substitute into the equation
m=(2-5)/(-7-3)
m=-3/-10
m=3/10
the slope is 3/10
before we put a line into standard form, we need to put it into another form first-- like slope-intercept form (y=mx+b, where m is the slope and b is the y intercept)
we already know the slope
here's our line so far:
y=3/10x+b
we need to find b; since the line will pass through the points (3,5) and (-7,2) we can use either one of them to find b
let's use (3,5) as an example. Substitute into the equation
5=3/10(3)+b
5=9/10+b
41/10=b
b is 41/10
this is the equation:
y=3/10x+41/10
now we can find the equation in standard form. Subtract 3/10x from both sides
-3/10x+y=41/10
a (the number in front of x cannot be negative OR less than one. First, let's multiply both sides by -1)
3/10x-y=-41/10
multiply both sides by 10 to clear the fraction
3x-10y=-41
^^ is the equation
hope this helps!
A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is 40 feet, the height of the roof is 10 feet, and the height of the entire silo is 75 feet?
a. 393,746.3 ft
b. 343,480.8 ft
c. 326,725.6 ft
d. 376,991.1 ft
Answer:
The answer is b. 343,480.8ft
Step-by-step explanation:
I thought it was c at first because I forgot to add the volume of the cone.
The equation for the volume of a cylinder is V=π×r²×h
The solution would look like V=π40²×65=326725.8
The equation for the volume of a cone is V=1/3πr²×h
The solution would look like V=1/3π×40²×10=16755
Adding the two volumes would equal 326725.8±16755= 343480.8

7x-6y=-43
2x=-2
Step-by-step explanation:
i hope this helps :)
Answer:
Step-by-step explanation:
The first step is to add the 2 equations This will eliminate the y terms
( + 6y + -6y = 0).

A backpack is on sale for 30% off. If the sales price is $15.75, what is the original price? Show your work.
Answer:
$22.50
Step-by-step explanation:
As it is 30% off, $15.75 is 70% of the full price. You can then divide 15.75 by 70 [= 0.225] to get 1% of the full price. Multiply 0.225 by 100 to get the full price. 0.225 x 100 = 22.5
We can check that this answer is correct by multiplying 22.50 by 0.7. If you get 15.75 you know the answer is correct as 15.75 is 70% of the full price.

what equation passes through (6,3) and is parrallel to y=3x+5
Answer:
y=3x+25
Step-by-step explanation:
For the equation y=3x+5, the slope is 3. Since the line will be parallel to it then this is the slope of the new line as well. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-13)=3(x--4)
y-13=3x+12
y=3x+25
You would like to lease a car worth $36,601 for a three-year period. The leasing company told you that after three years, the car would have a residual value of $15,818. How much of the car’s original value will you have to pay off during your three-year lease?
Answer:
$20,783
Step-by-step explanation:
The original value of the car is given as $36,601.
Now, the residual value of the car after a 3 - year lease is given as $15,818.
Residual value is the amount that the person leasing this car can purchase it after the 3 years lease is expired.
Formula for his residual value is usually;
Residual value = original value - depreciation value
Where depreciation value is the amount of the cars original value the Person getting the vehicle on lease for 3 years would pay to cover that period.
Thus;
Depreciation value = 36601 - 15818 = $20783
An airplane is flying in a direction of 75° north of east at a constant flight speed of 300 miles per hour. The wind is blowing due west at a speed of 25 miles per hour. What is the actual direction of the airplane? Round your answer to the nearest tenth. Show your work. PLS PLS PLSPLS HELP URGANT
Answer:
79.7°
Step-by-step explanation:
We resolve the speed of the plane into horizontal and vertical components respectively as 300cos75° and 300sin75° respectively. Since the wind blows due west at a speed of 25 miles per hour, its direction is horizontal and is given by 25cos180° = -25 mph. We now add both horizontal components to get the resultant horizontal component of the airplane's speed.
So 300cos75° mph + (-25 mph) = 77.646 - 25 = 52.646 mph.
The vertical component of its speed is 300sin75° since that's the only horizontal motion of the airplane. So the resultant vertical component of the airplane's speed is 300sin75° = 289.778 mph
The direction of the plane, Ф = tan⁻¹(vertical component of speed/horizontal component of speed)
Ф = tan⁻¹(289.778 mph/52.646 mph)
Ф = tan⁻¹(5.5043)
Ф = 79.7°

its 8 because the multiples of 6 are 6, 12, 18, 24, 30, 36, 48 then the multiples of 8 are 8, 16, 24, 32, 40, 48
Describe this sampling method: "Survey the first 40 students who enter the main
office".
Answer:
Convenience sampling
Step-by-step explanation:
From the question, we understand that 40 of all students are to be surveyed. This implies that from the 41st till the last student will not be a part of the survey.
When sampling is done, taking a part of the whole population that is near or readily available; such sampling is referred to as convenience sampling.
The whole population, in this case are all students while the convenience being selected are the first 40 students.

Mrs. Habib has 46.25 feet of border for a bulletin board for her classroom. the board is 37.5 feet tall and 8.3 feet wide. how many feet of border will Mrs habib have left after she puts border around the board?
It’s not 22.15 I’ve tried.
Answer:
Mrs. Habib will have 22.25 feet of border left after she puts border around the board.
Step-by-step explanation:
You must find the perimeter of the board and subtract it from the amount of border she has to find how much she will have left after she uses it. The formula for perimeter is [tex]P=2(l+w)[/tex], where [tex]l=[/tex] the length of the board, and [tex]w=[/tex] the width of the board. You will add those together and multiply them by 2 because there are 4 sides to a rectangle. That means this equation will look like:
[tex]P=2(8.25+3.75)[/tex]
Now you can just solve for the perimeter.
[tex]P=2(12)[/tex]
[tex]P=24[/tex]
The perimeter is 24 feet. That means it will take 24 feet of border to cover her board. In order to find out how much she'll have left over, just subtract 24 from the total amount of border she has.
[tex]46.25-24=22.25[/tex]
Therefore Mrs. Habib will have 22.25 feet of border left over after she covers the bulletin board.

Answer:
10.5 cm
Step-by-step explanation:
A line segment is defined as a part of a line. It is a straight line having two end points. The only difference between a line and line segment is that a line is continuous with indefinite length whereas a line segment has a definite length to it between the two points.
In the figure, the length of the line segment is 10.5 cm (rounded to the nearest tenth).
