Answer 1

Answer:

The distancetraveled in the period of 5 and 3\4 hours will be 287 miles and 1\4 miles.

Calculating the velocity of each moment we have:

Speed 1 :

$168 miles / 2.25 hours = 48 miles/hour$

Speed 2:

$48 + 5 miles/hour = 53 miles/hour$

calculating the distance of each moment we have:

Distance 1 = 168 miles

Distance 2:

$2.25 hours X 53 miles/hour =119.25 miles$

Calculating the total distance we have:

Total Distance = Distance 1 + Distance 2

= 168 + 119.25 miles = 287.25 miles

Answer 2

Answer: Speed 1 = 168 miles / 2.25 hours = 48 miles/hour
Speed 2 = 48 + 5 miles/hour = 53 miles/hour
Distance 1 = 168 miles
Distance 2 = 2.25 hours X 53 miles/hour =119.25 miles
Total Distance = Distance 1 + Distance 2 = 168 + 119.25 miles = 287.25 miles
Or 287 and 1/4 miles

If the equation y=mx+b is used to model a quantity y as a function of the quantity x, why is b considered to be the starting value?

Answers

Answer:

This is because even when the quality of the variable x is 0, the value of b still exists and is the starting point for y.

Step-by-step explanation:

To prove this, we start with the base form of the equation and input 0 for x.

y = mx + b

y = m(0) + b

y = 0 + b

y = b

Tara is the editor of the school newspaper. She tries to devote about 1/2 of the paper to news, 1/3 to pictures, and the remainder to advertising. About how much of the paper is devoted to news and pictures?PLEASE SHOW ALL WORK!
THANKS!

Answers

5/6 of the paper is devoted to news and pictures

first I made the fraction have equal denominators which was 6 by doing that I multiplyed the numerator and the denominator

1/2
1×3=3
2×3=6
therefore 1/2 being equivalent to 3/6

1/3
1×2=2
3×2=6
therefore 1/3 being equivalent to 2/6

now you would be able to add the numerators, so 2+3=5
therefore being 5/6 of the paper is devoted to news and pictures

How do you write 7.40 × 102 in standard form?

Answers

Answer:

I believe that the answer is 7.4 * 10^2 + 2

-- The answer to that equation is 754.8 if that was needed as well

Step-by-step explanation:

Please mark brainliest I would really like it if you did! I just want one brainliest...

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number)., so I believe the answer would be 7.4*10^2+2

Hope I helped :)

106 over 500 as a decimal number

Answers

106/500 as a decimal is: 0.212.

You can easily find the decimal of a fraction by doing long division or inserting the fraction in a calculator (which teachers usually allow their students to use a calculator even on tests... unless if the test is about long division, etc).

Long division is pretty hard to do without a pen and paper, but the steps to do long division are: divide the number on the right by the left number - multiply the number on the left by the top number - subtract the number on the right by the number below it - bring down, and then repeat if you can.

$(106)/(500)$
0.212

What number is bigger 2 7/8 or 2.79?

Answers

$(1)/(8)=(1\cdot125)/(8\cdot125)=(125)/(1000)=0.125\n\n(7)/(8)=7\cdot(1)/(8)=7\cdot0.125=0.875\n\n2(7)/(8)=2.875\ is\ bigger\n\n2(7)/(8)=2.875 > 2.79$

27/8 is bigger because when you divide 27 to 8 you will get 3.37 so 3.37 is bigger than 2.79.
