Answer:

k = 11

Step-by-step explanation:

k/90 - 1/9 = 1/90

k/90 = 1/90 + 1/9

k/90 = 1 + 10/90

k/90 = 11/90

k = 11/90 / 90

k = 11/90 * 90

k = 11

SOMEONE PLEASE HELP ME ASAP PLEASE !!!​
Ede4ka [16]

Answer:

530.66

Step-by-step explanation:

The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14

For this circle we do 3.14 * 13^2

First we have to square 13: 13^2 = 169

Then we multiply 169 by 3.14: 3.14 * 169 = 530.66

Then we do to the nearest hundredth which is the same as the previous answer: 530.66

pleaseeeeeeee HELPPPPPPPPPPPp In a parking lot, 25% of the cars are SUVs, and 40% are pickup trucks. The rest of the cars are se
Arisa [49]

Answer:

60 cars

Step-by-step explanation:

In order to find how many total cars are in the parking lot, you must use a ratio. This is what you know:

25% = SUVs

40% = pickups

X% = cars

100% - (25% + 40%) = 35%. Thus, the remaining 35% of the cars are sedans. Now, we use a ratio to find the TOTAL number vehicles. See below:

X/65% * 21/35% = 35x = (21x65) = 1,365 (Hint: remember cross-multiplying??)

35x = 1,365

x = 1,365/35

x = 60 total cars

Sanity check:

25% of 60 = 15 SUVs

40% of 60 = 24 pickups

35% of 60 = 21 sedans

TOTAL: 60 cars

Dovator [93]

Answer:

(-8,-5)

Step-by-step explanation:

Well, if we divide the square root of M by the hypotenuse due to the activation of the square root of A, then we can achieve the absolute equilibrium between both statements as we bring the oven to about 220 degrees Farenheit, the brownies will look great.
