Answer: 2√6
x² - y² can be factored as (x+y)(x-y), so we can write x² - y² = (x+y)(x-y). Plugging the values we already know for x² - y² and (x+y), we have 60 = 5√6 (x-y), so (x-y) = 60/(5√6) = 2√6.
i hope this was helpful! :D
please help me :)

the seventh grade class is putting on a variety show to raise money. it cost 700 dollars to rent the banquet hall that they are going to use. if they charge 15 dollars for each ticket, how many tickets do they need to sell in order to raise 1000 dollars. Write an inequality and a solution to the inequality.
Answer:
Since the question is partial, i will assume 2 scenarios:
They need to raise 1000 income
They need to make 1000 as profit
If $1000 as income:
Each ticket costs $15, so tickets would bring them $1000 income. Fractional ticket is not possible, so rounding gives us 67 tickets as the answer.
If $1000 as profit:
Their cost of renting is $700. We know that .
So, . So, to raise $1700, we need tickets. Fractional ticket is not possible, so rounding gives us 114 tickets as the answer.
ANSWER:
If need to raise atleast $1000 as income, they need to sell 67 tickets.
If need to raise atleast $1000 as profit, they need to sell 114 tickets.
The most probable answer would be 114 tickets

What is the slope of the line 3x – 9y = 4?
Answer:
Slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Write the equation in y =mx + c form
3x - 9y = 4
-9y = -3x + 4
[tex]y = \frac{-3x}{-9}+ \frac{4}{-9}\\\\y =\frac{x}{3} - \frac{4}{9}\\m = \frac{1}{3}[/tex]
Find the surface area of the 3D solid. Round to one decimal place.
Answer:
172.5
Step-by-step explanation:
The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place
Categorize each triangle by both sides and angles. Choose two for each question below.
Answer:
Obtuse
Step-by-step explanation:
Answer: scalene, and obtuse
Step-by-step explanation: All of the sides are different lengths so that makes it a scalene triangle. On the picture it also shows that one of the angles is 107 degrees. Since 107 is larger than 90, it is an obtuse triangle.
Find the gradients of lines A and B. NEED ASAP
Step-by-step explanation:
The line A, the slope is +2
And line B the slope is n-1
Answer:
For A;
x1 = -2, y1 = -3, x2 = 3, y2 = 7
Gradient = (y2 - y1)/(x2 - x1)
= (7 - (-3))/(3 - (-2))
= 10/5 = 2.
For B;
x1 = 7, y1 = -2, x2 = -2, y2 = 7
Gradient = (y2 - y1)/(x2 - x1)
= (7 - (-2))/(-2 - 7)
= 9/-9 = -1.
What is the value of x?
A. 142
B. 152
C. 76
D. 71
Answer:
x has a value of 71, making D the correct answer.
Step-by-step explanation:
Because this is an isosceles triangle, we know that the bottom two angles are equal. We also know that the sum of the angles inside a triangle will always come to 180°. With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.
[tex]x = (180 - 38) / 2\\= 142 / 2\\= 71[/tex]
So the correct answer is D, 71 degrees.
3(x - 1) <-3(2 – 2x)
solve the inequality
Answer:
3x-3<6x-6
Step-by-step explanation:
3(x)= 3x
3(-1) = -3
3x-3
-3(2) = -6
-3(-2x) = 6x
6x-6
(11x + 8) + (8x + 12) =27
Answer:
11x + 8 +8x +12 =27 (drop the parenthesis, there's no actual need for them)
19x +20 =27 (i combined like terms and then subtracted 20 from both sides)
19x = 7 (divide both sides by 19 to get x alone)
x= 7/19 or 0.36842105 (the answer)

A squirrel burrowed 6 holes in 2 minutes. How many holes could the squirrel burrow in 7 minutes
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
To determine how many he can burrow in 7 minutes, you would multiply the
unit rate of 3 holes in 1 minute by 7.
He would burrow 21 holes in 7 minutes.
Step-by-step explanation:
brainliest pls?
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
therfore your answer would be 21 holes in 7 minutes

The grid you see below is in the shape of a rectangle. What is the area, in square units, of the shaded part?
Answer:
I believe the answer would be 6
Step-by-step explanation:
Area = length x width
4 x 3 = 12
12/2= 6 because only half of the rectangle is shaded

A cone has a height of 19 yards and a radius of 7 yards. What is its volume
Use a 3.14 and round your answer to the nearest hundredth.
Answer:
Step-by-step explanation:
h= 19 yards, r=7yards, v=?,Π= 3.14
Vol. Of a cone = 1/3×h×Π×r²
V= 1/3×19×3.14×7²
V= 2923.34/3
V=974.45
To the nearest hundredth
V=974cm³
Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?
Answer:
Volume of a cylinder, V = πr^2h
but r= d/2
therefore, Vol = π(d/2)^2h
from the parameters given,
Vol = π(18/2)^2h
=81πh
