What is the missing numerator of 3 1/2=?/2

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

3 $(1)/(2)$ = 3 X 2 + 1

= 6 + 1

= 7/2

therefore, the numerator is 7 which is the figure at the upper part of the improper fraction

Answer 2

Answer:

Answer:

7 = ?

Step-by-step explanation:

3 1/2 is a mixed fraction

?/2 shows itself as an improper fraction

To have 3 1/2 turn into an improper fraction, you multiply the denominator(2) by the whole number(3)

3 x 2 = 6

With the remaining numerator, which is 1, you add it to the total product of 3 and 2, giving you 7

so if you have a right triangle with legs legnth a and b and a hypotonuse legnth c, then a^2+b^2=c^2 given in the comments is that a=15 c=20 input and solve 15^2+b^2=20^2 225+b^2=400 subtract 225 from boths ides b^2=175 take square root of both sides b=5√7

The therorem is:

$a^(2) + b^(2) = c^(2)$
or, solving for b:
$b = \sqrt{c^(2)-a^(2)}$

$b = \sqrt{20^(2)-15^(2)}$
$b = √(400-225)$
$b = √(175)$
$b \approx 13.23$

Solve -0.5(–2x+8) – 8 = 8.

Answers

Answer:

x = 20

Step-by-step explanation:

Firstly, we have to distribute: (-0.5 * -2x) and (-0.5 * 8) -8 = 8

1x - 4 - 8 = 8

Next collect like terms: 1x - 12 = 8

Isolate x to get the value of x: Add 12 to both sides

1x = 20

So x = 20

Answer:x=20

Step-by-step explanation: first you distribute the value outside of the parentheses

-0.5*2x= 1x

-0.5*8=-4

it then becomes

x-4-8=8

combine -4 and -8

x-12=8

add the 12 over

x=20

During a bike challenge,riders have to collect various colored ribbons. Each 1/2 mile they collect a red ribbon, each 1/8 mile they collect a green ribbon, and each 1/4 they collect a blue ribbon. Which colors of ribbon will be collected at the 3/4 mile marker?Explain.

At the 3/4 marker, the rider can collect a green ribbon and a blue ribbon.

Write a multiplication problem in which the product is between . 05 and . 75.I have looked at the answers, I don't understand how you get to those answers in the format in which you are doing it. And the answer that I get is not the answer that any of you are getting. Why is that?
I take . 05 and multiply it by . 75 which is . 0375
but that's not the answers you guys are getting.
Please help me I am so confused.

Answers

as far as I read you, the factors of the multiplication should be between 0.05 and 0.75, not being 0.05 or 0.75 but in between only.

a good example of that could be say 0.5 and 0.5, 0.5*0.5 = 0.25, and

0.05.................0.25........................................................0.75.

or say 0.15 and 3, 0.15*3 = 0.45 and

0.05...................................0.45.......................................0.75.
