What is the slope of the line? <br> y+3=-4(x+7)
strojnjashka [21]

We don't really have to put this in slope intercept form; it would clearly end up as

y = -4x + something

so we know the slope is -4.

Answer:  C)   -4

Gravel is being dumped from a conveyor belt at a rate of 15 ft3/min, and its coarseness is such that it forms a pile in the shap
gayaneshka [121]

Answer:

0.13 ft/min

Step-by-step explanation:

We are given that

\frac{dV}{dt}=15ft^3/min

We have to find the increasing rate of change of height of pile  when the pile is 12 ft high.

Let d be the diameter of pile

Height of pile=h

d=h

Radius of pile,r=\frac{d}{2}=\frac{h}{2}

Volume of pile=\frac{1}{3}\pi r^2 h=\frac{1}{12}\pi h^3

\frac{dV}{dt}=\frac{1}{4}\pi h^2\frac{dh}{dt}

h=12 ft

Substitute the values

15=\frac{1}{4}\pi(12)^2\frac{dh}{dt}

\frac{dh}{dt}=\frac{15\times 4}{\pi(12)^2}

\frac{dh}{dt}=0.13ft/min

The sum of two numbers is six, and the difference is 10. Find the numbers.
pashok25 [27]
First no. = x 
Second no. = y

Equation Formation
x + y = 6..........equation(i)
x - y = 10...........equation (ii)


x = 6 - y
6 - y - y = 10
6 - 2 y = 10
-2 y = 10 -6
-2 y = 4
   y = -2

x = 6 + 2
x = 8

Answer = 8 , -2

Ten large marbles weigh as much as 14 small marbles. How many large marbles weigh as much as 35 small marbles?
Paladinen [302]
To get the answer we can use proportion
10 large ------------- 14 small
x large -------------- 35 small
crossmultiply
10*35=x*14
350=14x            /:14
350:14=14x:14
25=x-its the answer
