the sum of 2 rational numbers is 5/2. if one of the number is -7/3. then find the other number.

Answers

Answer: the other rational number is -29/6

Step-by-step explanation:

5/2 + x = -7/3

x= -7/3 - 5/2 change to common denominator

x = -14/6 -15/6

x = -29/6

Check: 15/6 +(-29/6) = -14/6 = -7/3

Sal built a card table with a top area of 900 square inches. What is the length, in inches, of one side of the table?

Answers

Answer:
30

Explanation:
It’s pretty simple actually, you just need to get the square root of 900 by seeing what two equal numbers give you 900. The answer in this scenario would be 30 since 30x30 would give you 900. Since it is a square all sides are equal and your answer would only be 30.
Hope this helped you :)

Answer: 30 inches is the length of the sides.

Step-by-step explanation: Card tables are square. So you can take √900 = 30

An average fly has a mass of 0.048 grams. An average ant has a mass of 3.12 x 10^-3grams
Would 3.99 million flies or 47,000.000 ants have a greater mass?
Approxmately how much greater, in grams, would the greater mass be? Justity your answers Respond in the space provided​

Answers

Answer:

the flies have a greater mass

Step-by-step explanation:

First, we should solve 10^-3 = 0.001 "for the ants" it is NOT negative now 0.001 times 3.12=0.00312  to find the total fly mass we should just multiply 0.048 times 3990000=191520 and for the ants 0.00312 times 47million=146640 so now the answer would be that the flies has a greater mass

Answer:

the flight have greater mass

If the slope of a line is undefined, then the line is a vertical line, so it cannot be written in slope-intercept form, but it can be written in the form: x=a , where a is a constant. If the line has an undefined slope and passes through the point (2,3) , then the equation of the line is x=2 .

Tom is painting a fence 100 feet long. He starts at the West end of the fence and paints at a rate of 5 feet per hour. After 2 hours, Huck joins Tom and begins painting from the East end of the fence at a rate of 8 feet per hour. After 2 hours of the two boys painting at the same time, Tom leaves Huck to finish the job by himself.

Answers

Answer: 26 feet

Step-by-step explanation:

They have completed 26 feet in total I don’t really understand the question because I don’t understand what I am supposed to answer so I am kinda guessing on this one. Sorry if I am wrong

Answer:

6 hours

Step-by-step explanation:

distance=rate×time (or d=rt)to determine the total length of the fence Tom paints.

d=(5)(4)

d=20 feet

Subtracting this from the total length of the fence 100 feet gives the length of the fence Tom will NOT paint: 100−20=80 feet. If Huck finishes the job, he will paint that 80 feet of the fence. Using d=rt, we can determine how long this will take Huck to do:

80=8(t)

t=10 hours.

If Huck works 10 hours and Tom works 4 hours, he works 6 more hours than Tom.

Which equation represents a proportional relationship?
1. y = 7x – 3
2. y = 150x
3. y = 21/x
4. y = 2x + 1

Answers

The answer is number 1. y = 7x - 3

Equation 2. [tex]y = 150x[/tex] represents a proportional relationship.

Here  [tex]y=150x[/tex]

On rearranging we get, [tex]\frac{y}{x} =150[/tex]

Or, [tex]\frac{x}{y} =\frac{1}{150}[/tex]

Or, [tex]x:y=1:150[/tex]

from above expression we can say now equation 2 represents a proportional relationship and the other equations cannot show the proportional relationship.

Hence Equation 2. [tex]y = 150x[/tex] represents a proportional relationship.

What do I need to multiply to get my quotation

Answers

Answer:

6

Step-by-step explanation:

I believe this answer is 6 because you need to get common denominators first. So the fractions would be 6/8 and 1/8. Then you do the reciprocal which is 6/8 times 8/1. Then you multiply the numerators 6 and 8. Then the denominators 8 and 1. Then you do 48 divided by 8 (48/8) which is 6. You got this! :)
