The sum of two numbers is 45 and their product is 500

Answers

Answer 1

Answer:

If the sum of two numbers is 45 and their product is 500 the numbers are 25 and 20 respectively.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, The two numbers are a and b.

Given, a + b = 45...(1) and ab = 500...(2)

(a + b)² = a² + 2ab + b².

2025 = a² + b² + 1000.

a² + b² = 1025.

Now,

(a - b)² = a² + b² - 2ab.

(a - b)² = 1025 - 1000.

(a - b)² = 25.

(a - b) = 5....(3)

Now, Adding eqn(1) and eqn(2) we get,

2a = 50.

a = 25 and hence b = 20.

ricky found a beetle that has a body one fourth the length of the fraction strips used in problem 1.2. how many beetle. how many beetle bodies placed end to end would have a total length equal to the length of a fraction strip. ricky drew 13 paper beetle bodies end to end each the same length as the one found. how many fraction strips long is ricky line of beetle bodies.

Answers

1/4 of 1/4

= 1/8

13 x 1/8

= 13/1 x 1/8

= 1 5/8

therefore there are 1 and 5/8 in the line of rickys fraction strips.

on a fraction strip line this is 13/8

A scale for a scale drawing is 10cm:1mm. which is larger the actual object or drawing explain

Answers

If I'm understanding your question, the drawing is 10cm and for every 10cm, the drawing is etched 1mm. This means that no matter how big the drawing gets, the actual object will always be bigger since it's 10cm larger always than the drawing. Hope this helped!

How many solutions are there to the equations 5x+1=3x+7?

Answers

5x + 1 = 3x + 7

Subtract 3x to both sides:

2x + 1 = 7

Subtract 1 to both sides:

2x = 6

Divide 2 to both sides:

x = 3

So this equation only has 1 solution.

$5x+1=3x+7\n2x=6\nx=3$

Which number is 164,502,423 decreased by 100,000?

Answers

Hello!

This is very basic math.. So I should be able to help you :)
The correct answer you should have gotten is: $164, 402, 423$

You should have subtracted from the hundred thousands place, which would have brought you down "1" hundred thousand points. . .

Hope it Helped :)

If you'd want the answer you have to do 164,502,423 subtract 100,000 which all you have to do is subtract from the hundred thousands place which is in this case 500,000 so it would be 164,402,423. I hope i gave a good understanding :)

Mr.Jenkins wants to distribute 40 fliers. He distributed 30 fliers so far. What percent of the total number of fliers has Mr. Jenkins distributedÉ

Answers

$(30)/(40)= (3)/(4) \n\n (3)/(4) = (x)/(100) \n\n4*25=100\n3*25=75\n\n(75)/(100)\n\n75\%$

Just put 30 over 40. Now you have $(3)/(4)$
If you put that in decimal form it's .75. Now convert it to a percent and get 75%
