Answer:

3

Step-by-step explanation:

A'B'C'D' is 3 times bigger than ABCD, so to get back to the original we gotta count the length of B'C' and devide by 3

9 \div 3 = 3

Angle A and angle B are complementary angles. If m<A = x, which expression represents the number of degrees in angle B?
Usimov [2.4K]
Complimentary just means that they add to be 90, so you take 90 degrees and subtract the angle you already have in order to get the complementary angle

Given the arithmetic sequence with the following two
kondor19780726 [428]

Answer:

aₙ = -15 + 10 * (n-1)

Step-by-step explanation:

aₙ = a₁ + (n-1)*d       a₁: first term     d: common difference

a₅  a₁ + 4d =25 .... (1)

a₁₁  a₁ + 10d = 85   ...(2)

(2) - (1)     6d = 60

d = 10

a₁ = -15

Formula: aₙ = -15 + 10 * (n-1)

You deposit $2000 each year into an account earning 3% interest compounded annually. How much will you have in the account in 25
kozerog [31]

This is what I get.  Total will be 4187.56 with  Interest 2187.56.   By using the formula: To find amount : A=p (1+r/n)^n×t Where P=2000,r=3%,n=1,t=25 So plug in and solve  A=2000(1+0.03/1)^1×25   To find interest you use formula  A=p+I A=4187.56, p=2000,i= we need to find. 4187.56=2000+I 4187.56-2000=I 2187.56=i

Which of the following statements describes the process for solving 4x ≥ -24?
dezoksy [38]
Divide both sides of the inequality by 4 but don’t flip the symbol.

You only flip the inequality symbol if you divide by a negative number.

If you’re solving for x (which you are), you want to get x by itself. The only way to do that is to divide by 4.
