Answer:

C. c = 10

Step-by-step explanation:

You have to use the Pythagorean theorem:

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10

Answer:

c = 10

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + 8^2 = c^2

36+64= c^2

100 = c^2

Take the square root of each side

sqrt(100) = sqrt(c^2)

10 -c

a car rental agency charge 20 per day plus 30 cents per mile. if you had one of the car for 5 days and your total bill is $197.5

Flura [38]

Answer:

325 miles

Step-by-step explanation:

$20 for each day

5 days

$0.30 for each mile

20(5) + 0.3x = 197.5

100 + 0.3x = 197.5

100 - 100 + 0.3x = 197.5 - 100

0.3x = 97.5

$\frac{0.3x}{0.3} = \frac{97.5}{0.3}$

x = 325

Write each of these propositions in the form "p if and only if q" in English.

goldfiish [28.3K]

Answer:

The "p if and only if q" statement is equivalent to "q if and only if p", then let's rewrite all the propositions in this way.

a) "If it is hot outside you buy an ice cream cone, and if you buy an ice cream cone it is hot outside."

We can define:

q = is hot outside

p = you buy an ice cream cone

Then we can rewrite this as:

"You buy an ice cream cone if and only if is hot outside"

b) "For you to win the contest it is necessary and sufficient that you have the only winning ticket."

We can define:

p = you winning the contest

q = have the winning ticket

Then we can rewrite (changing some words) this as:

"You will win the contest if and only if you have the winning ticke"

c) "You get promoted only if you have connections, and you have connections only if you get promoted."

We can define:

p = you get promoted

q = you have connections

We can rewrite the proposition as:

"You can get promoted if and only if you have connections"

d) " If you watch television your mind will decay, and conversely."

We can define:

p = you watch television

q = your mind will decay

We can rewrite it as:

"You can watch television if and only if your mind decays"

e) " The trains run late on exactly those days when I take it."

We can define:

p = The train runs late

q = I take it.

We can rewrite the proposition as:

"The train runs late if and only if I take it"

You work at a clothing store, and your boss wants you to find out which type

dedylja [7]

The answer would be D. To find percentage, you would divide the partial number from the total number. In this case, 13/ 20 because 13 tank tops were sold out of 20. 13/20 is .65. To convert decimals to percentage, multiply by 100 and you would get 65% for the first one. Repeat for the next, 15/25, and you would get 60%. Therefore 65% is the greater percentage.

What's 1/2 as a whole number

WARRIOR [948]

Hey There!

$\frac{1}{2}$ can't really be a whole number, but converted to a decimal it is 0.5, and rounded to the nearest tenth, the answer would be one.

Rewrite the following radical expression in rational exponent form. (√x)5

ch4aika [34]

If you meant:
$( \sqrt{x})^5$

Then, let's change the square to read:
$(x^ \frac{1}{2})^5$

Now, we can just multiply the two powers, and your answer is:
$x^ \frac{5}{2}$

Hope I helped.
