Find the measure of CB.
Answer:
I'm Pretty Sure Its 40.
Step-by-step explanation:
Answer:
CB = 20.
Step-by-step explanation:
If the triangle is Isosceles, assuming that <D = <B according to the markings, CB must be 20 since 32 is the greatest side and therefore the hypotenuse, 20 is the smaller side and therefore either opposite or adjacent. Given that two sides must be the same, since CB is opposite of angle D which is congruent to angle B, CB = side opposite of angle B = 20.
what is uv + v u = –1 and v = –1.
Answer:
u=1/2
Step-by-step explanation:
if v=-1 then v is multiplying u, -u+ -u which gives -2u. to find u, divide both sides by -2 .-1/-2 the negative cancels the negative giving you positive number, which is 1/2

A regular pentegon is divided into five identical isosceles triangles. The area of the regular Pentagon is Bcm^2 . Write a formula for T, the area of one of the triangles
Answer:
B/5
Step-by-step explanation:
A regular pentagon has five sides of equal lengths. If each vertex of the regular pentagon is connected to its centre, you would have five identical isosceles triangles.
Hence, the five triangles all have equal areas. If the area of a triangle is Xcm², then
5X = B
X= B/5

When 3 times a certain number n is added to 6, the sum is 20 more than the original number. What is the number n?
Step-by-step explanation:
The equation would be:
3N + 6 = N + 20
Subtract N from each side:
2N + 6 = 20
Subtract 6 from each side:
2N = 14
Divide each side by 2:
N =7
Check:
3(7) + 6 = 7 + 20
21 + 6 = 27

If you make $2000 in Gross Income every month, but 35% is taken out in taxes, what will your monthly Net Income paycheck be?
The monthly net income paycheck would be $1300.
What is Net income:Net income is the profit or loss that a company or individual has after subtracting all expenses, taxes, and other deductions from the gross income earned in a given period of time. It is the amount of money that is left over after all the necessary deductions have been made.
The formula for calculating net income is:
Net Income = Gross Income - (Expenses + Taxes + Other Deductions)
Here we have
The gross income is $ 2000
The percentage of taxes = 35% of gross income
Hence, net income would be:
Net Income = Gross Income - Taxes
= $2000 - 35% of ($2000)
= $2000 - [ (35/100) × 2000 ]
= $2000 - [0.35 × 2000 ]
= $2000 - 700
= $ 1300
Therefore,
The monthly net income paycheck would be $1300.
