Kaylin mixed two liquids for a science experiment. One container held 7/8 cup and the other held 9/10 cup.what is the total amount of the mixture

Answers

Answer:

71/40

Step-by-step explanation:

We find the common denominator, which is 40,

so the first numerator is 9x4, and the second numerator is 7x5,

and adding them we get 71

and so the answer is numerator/denomitar = 71/40

Answer:

1 31/40 cup

Step-by-step explanation:

Add up the volumes to find the volume of the mixture:

7/8 + 9/10 = 5*7/5*8 + 4*9/4*10 =35/40 + 36/40 =71/40 =1 31/40 cup

Trigonometric functions

Answers

9514 1404 393

Answer:

β ≈ 39.9°

θ ≈ 50.1°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships between the sides of a right triangle and the trig functions of the acute angles.

For angle β, we know the opposite side and the hypotenuse, so the relevant relation is ...

Sin = Opposite/Hypotenuse

sin(β) = 61/95

The inverse function is used to find the angle when the sine is known.

β = arcsin(61/95) ≈ 39.9°

Of course, the angle θ is the complement of this:

θ = 90° -39.9° = 50.1°

Answer:

Step-by-step explanation:

sin β = 61/95 = 0.642105

β = 39.95 degrees.

O = 90 - 39.95

= 50.05 degrees

cos O = 61/95.

Note that cos (90-β) = sin β.

C:1 and 3/4

Step-by-step explanation:

We can use a ratio to solve

1 day x days

------- = -------------

24 hours 42 hours

Using cross products

1 * 42 = 24x

Divide each side by 24

42/24 = x

21/12 = x

7/4 = x

4/4 + 3/4 =x

1 3/4 =x

・x = 50

・y = 61

step-by-step explanation:

・first things you should know —

y + 8 + 2x + 11 = 180 ( supplementary angles equal to 180° )

・five sides add up to 540° ( pentagon! )

・therefore:

108 + 125 + 98 + 98 + 2x + 11 = 540

440 + 2x = 540

2x = 100

・x = 50

use what you know and plug in ;

y + 8 + 2x + 11 = 180

y + 8 + 2(50) + 11 = 180

y + 119 = 180

・y = 61

・you can always plug in or substitute to check your answers.ᐟ

Answers

Ok so one gallon is 400 and you want to cover 688 x 2
688 x 2 is 1376. Now you divide 1376 by 400.
You now know that to paint the walls with two coats of paint will cost you four cans of paint.
