Step-by-step explanation:

Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.

A-(5)(0.6)*7=21

B-(4/5)(15)+8=(0.8)(15)+8=20

C-4(8+2)/2=4(10)/2=40/2=20

D-14+4(2+3)=14+4(5)=14+20=34

Convert 2 18/240 to an improper fraction in the lowest terms. Show all work.

(Please be serious about this, I need help with math and I'm not that good at it, thank you.)

Answers

Answer:

498/240

Step-by-step explanation:

First lets recognize how many wholes we have ==== 2

Because our denominator is equal to 240, we know that one whole is equal to 240/240. However, we have 2 wholes there for our fraction is 480/240. Lastly, we can't forget about the remaining 18/240. If we add this on the previous result(480/240), then our final answer is 498/240.

Hope this helps!

The value of an improper fraction in the lowest terms is,

⇒ 83/40

What is mean by Fraction?

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

Number is,

⇒ 2 18/240

Now, We can change the number into an improper fraction in the lowest terms as,

⇒ 2 18/240

⇒ (240 × 2 + 18) / 240

⇒ (480 + 18) / 240

⇒ 498 / 240

⇒ 249 / 120

⇒ 83/40

Thus, The value of an improper fraction in the lowest terms is,

⇒ 83/40

Step-by-step explanation:

It is a right triangle, so it can be solved with the Pythagorean Theorem.

Answer:

Step-by-step explanation:

Length of PR = 40 units

Length of RQ = 70 units

ΔPQR is a  right angle. So, to fin the length of PQ, use Pythagorean theorem

hypotenuse² = base² + altitude²

PQ² = PR² + RQ²

       = 40² + 70²

       = 1600 + 4900

       = 6500

PQ = √6500 = 80.62 units

PQ = 80.62 units
