Mathematics
1 answer:
omeli [17]2 years ago
7 0

Answer:

= 3 + 6/15 + 10/15

Step-by-step explanation:

To make 2/5 into a fifteenth, you have to multiply the 5 by 3 to get 15. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 2 by 3 to get 6 on top.

To make 2/3 into a fifteenth, you have to multiply the 3 by 5 to get 15. Whatever you do to the top you have to do to the bottom, meaning that you have to multiply 2 by 5 to get 10 on top.

This is the same rule for all equations involving fractions.

What is the domain of the function y=2/x-6?
Alinara [238K]

Step-by-step explanation:

TO FIND THE DOMAIN OF THIS FUCTION AVOID SITUATIONS LIKE Y=2/0 FOR THIS IS UNDEFINED.

TAKING THE DENOMINATOR AND EQUATING IT TO ZERO

=> X – 6 =0

=> X=6

SO AVOID HAVING X = 6 IN THE DENOMINATOR FOR WHICH THE FUNCTION WILL BECOME UNDEFINED

THEREFORE, X ≠6

DOMAIN ={ X£R, x ≠6}

I.e all real numbers except 6

Five swimmers entered a competition. Four of the swimmers have had their turns. Their scores are 10.8s, 10.75s, 10.79s and 10.81
Shalnov [3]

Answer:

10.74s or faster (lower)

Step-by-step explanation:

The lowest time out of all of them is 10.75, so to all the 5th swimmer needs to do to win is to undercut the swimmer who got 10.75s by a 100th of a second. i.e 10.74s or faster (lower) would win.

If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.
PSYCHO15rus [73]

Answer: OPTION D.

Step-by-step explanation:

The formula for calculate the circumference of a circle is:

C=2r\pi

Where <em>r</em> is the radius.

The formula for calculate the area of a circle is:

A=r^2\pi

Where <em>r</em> is the radius.

Solve for <em>r</em> from A=r^2\pi to calculate it:

r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft

Subsitute the radius into C=2r\pi. Then:

C=(2)(4.296ft)\pi=26.99ft
