supppose v varies direcly as g, and v= 36 when g=4. Find v when g =11

Answers

Answer:

v = 99

Step-by-step explanation:

Given v varies directly as g then the equation relating them is

v = kg ← k is the constant of variation

To find k use the condition v = 36 when g = 4 , then

36 = 4k ( divide both sides by 4 )

9 = k

v = 9g ← equation of variation

When g = 11 , then

v = 9 × 11 = 99

in the diagram the measure of angle one is 3X the measure of angle two is 12 X what is the measure of angle 4

Answers

Answer:

144°

Step-by-step explanation:

m<1 =3x

m< 2= 12x

1&2 are supplementary angles, so

3x+12x= 180

15x=180

x= 12°

measure of angle 4 equals the measure of angle 2

because they're head opposite angles

m<4= 144°

A 5 foot tall pole casts a 3 1/3 foot shadow. At the same time an oak tree casts a 20 foot shadow. How tall is the tree?

Answers

Answer:

30 feet tall

Step-by-step explanation:

Set up a proportion where x is the height of the tree

[tex]\frac{5}{3\frac{1}{3} }[/tex] = [tex]\frac{x}{20}[/tex]

Cross multiply and solve for x:

100 = 3[tex]\frac{1}{3}[/tex]x

30 = x

So, the tree is 30 feet tall

Find the slope of each linear graph to solve the riddle.

( i just need help with V)

Answers

Answer:

slope=15÷10=1.5 or 3/2

Step-by-step explanation:

slope=rise÷run

10 right 15 up

slope=15÷10=1.5 or 3/2

The slope is calculated as the ratio of the rise and run. The slope of the given line will be [tex]\dfrac{3}{2}[/tex].

In mathematics, slope refers to the measure of the steepness or inclination of a line. It describes how much a line slants or rises/falls as it moves horizontally.

A positive slope means the line is upward-sloping, rising from left to right, while a negative slope indicates a downward-sloping line.

The slope can be calculated by the ratio of the rise and the run. The points on the given graph are A(10,30) and B(20,45). The slope is calculated by the formula written below,

[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

The slope of the line is calculated below

[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\m = \dfrac{45-30}{20-10}\\m = \dfrac{3}{2}[/tex]

The slope of the line will be  [tex]\dfrac{3}{2}[/tex].
