Mathematics

Answer:

the third one

Step-by-step explanation:

the square root of 25 is 5. 5+2 = 7.

this is a rational number (the set of all integers and fractions).

the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.

45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.

Help me determine if this function is even or odd!

If u end up with the exact same function that you started with (that is, if f (−x) = f (x), so all of the signs are the same), then the function is even if u end up with the exact opposite of what you started with (that is, if f (−x) = −f (x), so all of the signs are switched) then the function is odd

A varsity boy's basketball team has ratio of seniors to juniors that is 7:4. If the team is made up of only juniors and seniors,

DENIUS [597]

Answer:

The ratio of seniors to the total team members is 7: 11

Step-by-step explanation:

Let us solve the question

∵ A varsity boy's basketball team has a ratio of seniors to juniors that is 7: 4

∴ seniors: juniors = 7: 4

→ That means seniors have 7 parts and juniors has 4 parts

∴ The seniors' members = 7 parts

∴ The juniors' members = 4 parts

→ Add them to find the total parts of the team

∴ The team's members = 7 + 4 = 11 parts

→ To find the ratio of the seniors' members to the total team's member

divide their parts

∵ The seniors ÷ The total = $\frac{7}{11}$

∵ The seniors' member : The team's members = 7: 11

∴ The ratio of seniors to the total team members is 7: 11
