Write 3x+4y=12 in slope intercept form

2 answers:

5 0

Ok, let’s take it step by step.
In order to write an equation in slope intercept form, solve for y.
3x+4y=12
First, subtract 3x from both sides.
4y=-3x+12
Now, divide both sides by 4.
y=-3/4x+3.

So, 3x+4y=12 written in slope intercept form is y=-3/4x+3.

Find the volume of a right circular cone that has a height of 17.1 in and a base with a

padilas [110]

Answer:

Volume of the right circular cone = 1188.79 cubic inches

Step-by-step explanation:

Height of the cone = 17.1 inch

Circumference of the cone= 16.3 inches

Radius = 16.3/2

= 8.15 inch

Volume of the cone is:

$=\pi *r^2*\frac{h}{3}$

As, $\pi =\frac{22}{7}=3.14$

Volume of the cone

$=3.14*(8.15*8.15)*\frac{17.1}{3} \\\\=3.14*(8.15*8.15)*5.7\\\\=3.14*66.42*5.7\\\\=3.14*378.59\\\\=1188.79inch^3$

Volume of the right circular cone is 1188.79 cubic inches

Calculate the percentage change (increase or decease) that occurs when:

SashulF [63]

The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.

So;

a) change = Ι60 - 25Ι = 35.

ratio of change to original = 35:25,

multiplying by 100% will give 35/25 × 100% = 140%.

Hence it is a 140% INCREASE.

b) change = | 30 - 66 | = 36

the ratio is 36:66

multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%

Hence it is a 54.5% DECREASE.
