Three numbers are in the ratio 3:4:5. If the sum of their cubes is 216000, find the largest of these three numbers.
Answer:
50
Step-by-step explanation:
Let the numbers be 3x, 4x, 5x
(3x)^3 + (4x)^3 + (5x)^3 = 216000
27x^3 + 64x^3 + 125x^3 = 216000
216x^3 = 216000
x^3 = 1000
x = 10
5x = 5(10) = 50
Answer: 50

what is the slope of the line that passes through the points (0, –7) and (–4, 3)? (I just gave all my points plss help me)
Answer:
The answer is
[tex] \huge - \frac{5}{2} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
From the question we have
[tex]m = \frac{3 - - 7}{ - 4 - 0} = \frac{3 + 7}{ - 4} = - \frac{10}{4} = - \frac{5}{2} \\ [/tex]
We have the final answer as
[tex] - \frac{5}{2} \\ [/tex]
Hope this helps you
Find the slope between the given two points.
Please help...
Answer:
8/-5
Step-by-step explanation:
the equation for slope is y 2 - y 1/ x 2 - x 1 so your equation is -7 - (-11) / -6 - (-1) which simplifies to 8/ -5 and that is the slope.

D) 17
Answer:
45/3 or 15 simplified
Step-by-step explanation:
so b. 15
Answer:
Quick answer is B
Step-by-step explanation:
Use the rise over run method Y2-Y1 over X2-X1 and get your fraction. Divide your fraction to get your number and you get 15. Your equation should be simalar to this 75-30 over 5-2= 45 over 3 which is equal to 15.

Mr. Gomez bought fruit to make fruit salad. He bought 2 ½ pounds of apples and spent $4.50 on apples and oranges . Write and solve an equation to determine the number of pounds of oranges Mr. Gomez bought.
Answer:
Amount of orange = 1.25 pound
Step-by-step explanation:
Given:
Total amount of apple = 2.5 pound
Total cost = $4.5
Missing cost;
Orange = $1.2 per pound
Apple = $1.2 per pound
Computation:
Assume amount of orange = x
So,
1.2(x) + 2.5(1.2) = 4.5
1.2 x + 3 = 4.5
1.2 x = 1.5
x = 1.25 pound
Amount of orange = 1.25 pound
Jane invested her savings in two investment funds. The amount she invested in Fund A was $6000 less than the amount she invested in Fund B. Fund A returned a 8% profit and Fund B returned a 2% profit. How much did she invest in Fund B, if the total profit from the two funds together was $1220 ?
Answer:
Jane invested $37,000 in Fund B.
Step-by-step explanation:
Let;
IA = Amount invested in Fund A = $6,000
IB = Amount invested in Fund B = ?
PA = Amount of profit from Fund A = IA * 8% = $6,000 * 8% = $480
PB = Amount of profit from Fund B = IB * 2%
Therefore, we have:
Total profit = PA + PB = $1220 ........................ (1)
Substitute the relevant values into equation (1) and solve for IB, we have:
$480 + (IB * 2%) = $1220
IB * 2% = $1220 - $480
IB * 2% = 740
IB = 740 / 2%
IB = $37,000
Therefor, Jane invested $37,000 in Fund B.
