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

Answer for 7: C
Answer for 9: A
Step-by-step explanation for 7:
Because the variable is an exponent, we know there are no real numbers which cannot be placed in the exponent. Therefore, the domain is all real numbers.
Step-by-step explanation for 9:
Test a few values for x. Notice as the x value gets higher, the y value gets exponentially higher. Notice as the x value gets lower, the y value approaches 0, but no value of x will have y equal to or less than 0. Therefor, the asymptote, or line that cannot be crossed is 0 - making A the correct solution.

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].

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
