first we represent the unknowns using variables:
let x = measure of angle 4
let 3x+4 = measure of angle 3 (from the second statement)
then we set-up the equation. since the angles form a linear pair, their sum is equal to 180 degrees. therefore,
x + 3x + 4 = 180
4x + 4 = 180
4x = 176
x = 44 degrees (measure of angle 4)
3x + 4 = 136 degrees (measure of angle 3)
Answer:
Ok so you just ask your teacher, if not ur mom. I feel you can work this one out yourself.
Step-by-step explanation:
Answer:
{-7, 2, 8}
Step-by-step explanation:
We see that the domain is limited to three x-values: -3, 0 and 2. To find the range (which is the set of all y-values) we just need to plug-in these x-values and find the corresponding y-values.
So our equation is:
y = 3x + 2
Then we substitute for the x-values:
y = 3(-3) + 2
y = -9 + 2
y = -7
y = 3(0) + 2
y = 0 + 2
y = 2
y = 3(2) + 2
y = 6 + 2
y = 8
So our range would be {-7, 2, 8}.
Answer:
Step-by-step explanation:
1. ¹/₃ × π × r² × l:so 33.9.29cm³
2. π × r² × l:so π x 2² x 3.5=43.98ft³
3.¹/₃ × π × r² × l, to get the radius from diameter you divide the diameter by 2 so it would look like: ¹/₃ × π x 4² x 12= 201.06in³
4.352cm³
5. cone: 1/3 πr²h
Cylinder: πr²h
cone : 33 Cylinder = 3 x 33 = 99 in³
