Answer:
y = -90x + 2000
Step-by-step explanation:
Hello There!
So we need to write an equation of the line in slope-intercept form
y = mx + b
where m = slope and b = y intercept
They give us everything in the caption
They say that a hot air balloon descends from 2000 feet at a constant rate of 90 feet per minute
Descends from 2000 feet indicates that the hot air balloon starts at 2000 feet
Thus this is the y intercept
Descends indicates that the slope is going to be negative because descend means to go down
The hot air balloon descends at a constant rate of 90 feet per minute
Thus meaning that the slope is -90
Now that we have everything we add it all together and get that the equation is
y = -90x + 2000
hope this helps :)
Answer:
y = -90x + 2000
Step-by-step explanation:
in y = mx+b, m is the slope and b is the y intercept
Therefore the y intercept is 2000
Now we have y = mx + 2000
Because the balloon descends at 90 ft/min, the m value is -90
So the answer is y = -90x + 2000

Joshua has 2 ¾ times as many stamps as Leo. How many stamps must Joshua give to Leo so that each of them will have 210 stamps?
Show your work
Answer:
Joshua has to give Leo 93.75 (or 93 3/4) of his stamps
Step-by-step explanation:
210x2=240
210/4=52.5
52.5x3=157.5
157.5+240
So Joshua has 397.5 stamps
397.5-219=187.5
So there's a 187.5 difference
187.5/2=93.75
397.5-93.75=303.75
210+93.75=303.75

9. Expand using identites.
1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.
Solve the following equation 12 = 4 + 4(m + 1)

How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

The net below has dimensions l = 14 feet, w = 7 feet, and h = 13 feet. How will the surface area of the figure change if the width decreases by 2 feet?
Step-by-step explanation:
So, we know that the width in this image has a length of 7 feet. decreasing it by two will give us 5 feet. Now, we can solve the surface area.
Lateral faces: 7 x 14 x 4 = 392
Bases: 14 x 13 x 2 = 364

I need help with this question, I'm not very good at math and all help is appreciated!
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
