The spinner has eight possible outcomes. Fractions 6 and 3 are double the size of the rest of the sections, so one of them is equal to 2 small pieces. The probability of any one of them is 1/8.

Suppose a lab need to need to make 400 liters of 39% acid solution, but the only solutions available to the lab are 20% acid and

Maslowich

Answer:

c + d = 400

0.2c + 0.5d = 156

Step-by-step explanation:

Let

c = number of liters of 20% acid solution

d = number of liters of 50% acid solution.

c + d = 400 (1)

0.2c + 0.5d = 400(0.39)

0.2c + 0.5d = 156 (2)

From (1)

c = 400 - d

Substitute c = 400 - d into (2)

0.2c + 0.5d = 156 (2)

0.2(400 - d) + 0.5d = 156

80 - 0.2d + 0.5d = 156

- 0.2d + 0.5d = 156 - 80

0.3d = 76

d = 76/0.3

d = 253.33 liters

Substitute d = 253.33 into (1)

c + d = 400

c + 253.33 = 400

c = 400 - 253.33

c = 146.67 liters

Find the median number of magazines purchased in a store by 4 customers. 10, 55 , 34, 21

kkurt [141]

Median of 10, 55, 34, 21

First we arrange number in ascending or descending

10, 21, 34, 55 in ascending.

Median is the middle number and this is between 21 and 34.

We find the average:

(21 + 34) /2 = 55/2 = 27.5

Median is 27.5.

A giraffe can run 12 meters per second. Rounded to the nearest tenth, how fast is this in miles per hour? (1 mile= 1609 meters)

Vikki [24]

Answer: A giraffe can run 26.5mph

Step-by-step explanation:

12 times 60 (seconds) times 60 (minutes) = 43200. This is the total number of meters traveled in an hour. You would divide this by 1609 to get the total number of miles per hour.

Given sin (-theta) = 1/5 and tan theta = sqrt.6/12

stich3 [128]

Given $sin (\theta) = \frac{1}{5}$ , and $tan \theta = \frac{\sqrt{6} }{12}$ , then:

$cos\theta=\frac{2\sqrt{6} }{5}$

<h3> Computations on trigonometric identities</h3>

From the details provided:

$sin (\theta) = \frac{1}{5}\ \\\\tan \theta = \frac{\sqrt{6} }{12} \times \frac{\sqrt{6} }{\sqrt{6} }\\\\tan \theta = \frac{\sqrt{6} \times \sqrt{6} }{12 \times \sqrt{6} }\\\\tan \theta =\frac{1}{2\sqrt{6} }$

From the relationship above:

Opposite = 1

Adjacent = $2\sqrt{6}$

Hypotenuse = 5

$cos\theta=\frac{Adjacent}{Hypotenuse} \\\\cos\theta=\frac{2\sqrt{6} }{5}$
