You leave home and walk 3 blocks east, then 4 blocks north. How far are you from

home?

Answers

I believe the answer would 5 blocks

If you go 3 blocks East and 4 north, they are like the straight sides of a triangle, so to find the diagonal distance, or the shortest distance, you would find the diagonal side of a triangle it is
A squared + B squared = C squared

So 3x3 = 9
And 4x4 = 16
16+9=25
And the square root of 25 is 5

you get $2,000 loan at 9% interest rate and pays it back in 6 months. how much intereast will you pay on the loan

Answers

Answer:

$90

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

I = 2000 × 0.09 × 0.5 = 90

I = $ 90.00

The simple interest accumulated

on a principal of $ 2,000.00

at a rate of 9% per year

for 0.5 years is $ 90.00.

t= [−(−33)±√{(−33) ²−4×16×16)}]/(2×16)

What is the volume of a rectangular prism that has a height of 2 inches a width of 2 and 1/2 inches and a length of 5 and 1/2 inches?

Answers

Answer:

V = 27.4 in^2

Step-by-step explanation:

Converting to mixed numbers with fractions in decimal format makes this problem easier.  2 1/2 inches is the same as 2.5 inches; 5 1/2 inches is 5.5 inches.

The volume formula is V = L*W*H.

Here, V = (5.5 in)(2.5 in)(2 in), or 27.4 in^2

Step-by-step explanation:

A school ordered 32 orange shirts, 29 blue shirts, and 34 green shirts. The shirts are being divided equally among 6 classrooms. If each classroom gets the same number of shirts, how many shirts will be left over?
A.
2
B.
4
C.
5
D.
3

Answers

Answer: D

Step-to-step explanation:

Answer:

C

Step-by-step explanation:

The orange shirts will have 32/6 = 5 with 2 left over

The blue shirts will have 29/6 = 4 with 5 left over

The green shirts will have 34/6 = 5 with 4 left over

The left overs are 2 + 5 + 4 = 11 but I have divided the colors equally. If color does not matter then the total number of shirts = 32 + 29  + 34

The total number of shirts is 95

95/6 = 15 with a remainder of 5

So 5 shirts will be left over.
