Answer 1
Answer:

A triangles three angles always sum up to 180 degrees. We must find angle B.

We already have angle A and C, so it's quite simple.

Angle A is 28*, and angle C is 36*

We add these two together

28 + 36 = 64

Now we subtract

180 - 64 = 116

Angle B = 116*


Hope this helps you! (:

What is the volume of the a cube with a side of length 11 unitsA. 33 units
B. 121 units
C. 1331 units
D. 14641 units

Answers

The volume of a cube is

(length of a side) x (length of a side) x (length of a side)

usually written as  (length of a side)³  or (length of a side) cubed.

If the length of a side is 11 units, then the volume is

(11 units) x (11 units) x (11 units)  = 1,331 units-cubed.

None of the choices on the list is correct.  The nearest one is 'C'. 
It has the correct number but the wrong units.
Volume of a cube is
Volume=length×width×height

Substitute in the value
Volume=11×11×11

Volume=1331

The answer to your question is C. The volume of a cube with a side length 11 is 1331.

True or False? 1. All real numbers are either rational or irrational?

2. Every real number can be represented as a decimal, and every decimal represents a real number?

Answers

"Every real number can be represented as a decimal, and every decimal represents a real number"
 
Every real number can be represented as a decimal --> True since non-terminating decimals are decimals too.
 
And every decimal represents a real number --> This is just the vice versa of the first statement. Hence true.
 
That's making the whole statement true.So both the statements are true.

On a given morning the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F?A) Fall 8°F
B) Fall 3°F
C) Rise 8°F
D) Rise 5°F

Answers

Fall 3°F to return to the initial temperature of 71°F so option (B) will be correct.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that,

Initial temperature = 71°F

The temperature dropped 5°F = 71 - 5 = 66°F

Then rose of 8°F = 66 + 8 = 74°F

So,

The temperature has risen by 3°F so it needs to fall to match the initial temperature.

Hence "Fall 3°F to return to the initial temperature of 71°F".

Alan Cohl obtained an installment loan for $3,560. His finance charge is $308.56, and he will make 18 monthly payments. What is the APR?

Answers

The required APR is 56.01%.

What is APR?

The annual percentage rate (APR) is the cost of borrowing money expressed as a yearly percentage. It provides a more comprehensive picture of a loan's cost than the interest rate alone. It includes the interest rate, as well as any discount points or other costs.

A good APR is around 16%, which is the current credit card average. Individuals with poor credit may only have access to higher-interest credit cards. Some consumers with good credit may be able to obtain cards with interest rates as low as 12%.

Alan Cohl obtained an installment loan for $3,560.

His financecharge is $308.56, and he will make 18 monthly payments.

We know that

Annual percentage rate = monthly rate x 12

Now, the total interest

= 308.56 x 18 - 3560

= $1994.08

and, monthly interest = 1994.08/12 = 166.173

Also, the monthly rate = 166.173/3560 =4.7%

Thus, the APR = 4.7 x 12

APR = 56.01%

Annual percentage rate = monthly rate * 12
total interest = 308.56*18-3560 = 1994.08
monthly interest = 1994.08/12 = 166.173
monthly rate = 166.173/3560 =4.7%
APR = 4.7*12 = 56.01%
