Answer 1

Answer:

a+b=70

a-b=36

a=36+b

36+b+b=70

2b+36=70

2b=34

b=17

a=53

So the two results are 17 and 53.

You go to Trader Joes with your older sister to pick up avocados to make guacamole. Trader Joes sells 4 avocados for $3.50 or 6 avocados for $5.00. Which is a better deal?

Answers

The better deal would be 6 for $5.00 because if you take 4/3.50=0.875 6/5=1.2 now that we know how much we would be paying for each option you take 0.875*6=5.25 so you would be paying more for the first one when u can get a greater quantity-for cheaper. Hope this helps:)

A loan for $4,000 is given at a 6% interest rate for 2 years. Find the simple interest owed on the loan.

Answers

Answer:

I = $ 480.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 4000 × 0.06 × 2 = 480

I = $ 480.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 6% per year

for 2 years is $ 480.00.

A = $4,480.00

I = A - P

Equation: A = P(1 + rt)

Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.

Solving the equation:
A = 4000(1 + (0.06 x 2)) = 4480
A = $4,480.00

The total amount accrued, principal plus interest, from simple interest on a principal of $4,480.00 at a rate of 6% per year for 2 years is $4,480.00

PLEASE HELP Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell.

Answers

Answer:

1. Is A'B'C'D' a translation, rotation, or reflection of ABCD? Explain how you can tell.

A'B'C'D' is a reflection over the y-axis. By flipping ABCD over the y-axis, the result will be A'B'C'D'

2. Is A"B"C"D" a translation, rotation, or reflection of A'B'C'D'? Explain.

A"B"C"D" is a rotation of A'B'C'D'. This is proven by the fact that if A'B'C'D' is rotated 90 degrees, the result will be A"B"C"D".

3. Suppose the measure of ∠B is 89°. Which other angles must measure 89°? How do you know?

If ∠B measures 89 degrees, then all other B angles must also measure 89 degrees because the angle is not changed by any of the transformations performed.

4. What is the perimeter of A"B"C"D"? Explain how you found the perimeter.

Because the size and shape are not any different from the original figure, the perimeter is 26.3 units.

The price of a gallon of unleaded gas was $2.87 yesterday. Today, the price fell to $2.82. Find the percentage decrease. Round your answer to the nearest tenth of a percent.​

Answers

Answer:

1.7$

Step-by-step explanation:

Given

original price = $2.87

New price = $2.82

Percentage decrease = original price-New price/New price × 100

Percentage decrease = 2.87-2.82/2.87× 100

Percentage decrease = 0.05/2.87 × 100

Percentage decrease = 5/2.87

Percentage decrease = 1.7%

Suppose cos(O) = 5/13, Quadrant I. Find sin(O).
A:13/12
B:12/13
C:13/5
D:5/12

Answers

Answer:

B. 12/13.

Step-by-step explanation:

Using the identity sin^2 O + cos^2 O = 1:

sin^2 O = 1 - cos^2 O

sin^2 O = 1 - (5/13)^2

= 1 - 25/169

= 169/169 - 25/169

= 144/169

So sin O = √(144/169)

= 12/13.
