Solve for x. Round to the nearest tenth of a degree, if necessary.
babymother [125]

Answer:

x ≈ 40.0°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = \frac{opposite}{adjacent} = \frac{WX}{VW} = \frac{57}{68} , then

x = tan^{-1} (\frac{57}{68} ) ≈ 40.0° ( to the nearest tenth )

There are 5 questions listed below. Each question includes:
Tom [10]

a. 22. 79 - amount

b. 129   -   amount

c. 358. 3  - base

d. 40. 65%  - percent

e. 2. 58% - percent

<h3>How to determine the values</h3>

It is important to note that a percentage is the number or ratio expressed as a fraction of 100.

It is denoted using the percent sign, "%"

a. What number is 53% of 43

= 53/ 100 × 43

= 0. 53 × 43

= 22. 79

b. 43% of 300

= 43/ 100 × 300

= 129

c. 12% of what number is 43

12/ 100 × x = 43

x = 43 × 100/ 12

x = 358. 3

d. 43 is what percent of 106

43/106 × 100/ 1

4300×/ 106

40. 5%

e. What percent of 43 is 6

43/ 100 × 6

2.58%

Thus, the percentage of a value is that value divided by 100

Gnom [1K]

Answer:

B

Step-by-step explanation:

A is wrong, it increases

C is wrong, the coefficient does not determine if it is linear (straight), the exponent does.

D is wrong, you don't need to know a point to determine if it is linear, (if you have 3 points you can though. )

Which two rooms have an
alexgriva [62]

Answer: room 101 and room 107

Step-by-step explanation:

In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3

In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.

In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3

Therefore, room 101 and room 107 have the same ratio.
