Round value of x. Round the answer to the nearest tenth.

Mathematics
1 answer:
Mrrafil [7]3 years ago
6 0

Answer:

Step-by-step explanation:

From the given right angle triangle,

the hypotenuse of the right angle triangle is 25

With ∠ 31 degrees as the reference angle,

the adjacent side of the right angle triangle is the unknown side.

the opposite side of the right angle triangle is x.

To determine x, we would apply

the Sine trigonometric ratio.

Sin θ, = opposite side/hypotenuse. Therefore,

Sin 31 = x/25

x = 25Sin31

x = 25 × 0.5150

x = 12.875

Beverage A and Beverage B are sold in identical cans. Beverage A is 6% sugar. The portion of Beverage B that is sugar is 0.21. H
muminat

Answer:

3.5 more times sugar in B

Step-by-step explanation:

We need to see that the fact that Beverage B is 0.21 sugar can be translated to percentages, just by multiplying and dividing by 100 to get it easier to see:

0.21 * 100 /100 =  21/100 = 21% percent

This means that for every 100 units, 21 are sugar.

Now we can compare percentages directly, as both have the same volume because are sold in identical cans. We need to get how many times is 21 greater than 6. The only thing we need to do is the ratio between them:

21/6= 3.5

This implies that 21 is 3.5 greater than 6, you can verify it by multiplying 6 by 3.5 and getting 21.

So, B has 3.5 times more sugar than A.

Find the value of x from this adjoining figure
Fiesta28 [93]

Answer:

x=15^\circ

Step-by-step explanation:

Please refer to the attached figure for labeling of given diagram:

We are given the following angles:

\angle AOC = 3x^\circ\\\angle BOD = 2x^\circ\\\angle EOF = 7x^\circ

Angles opposite to each other when they are formed by crossing of two lines are known as vertically opposite angles. And vertically opposite angles are always equal to each other.

Using property of vertically opposite angles:

\angle EOF = \angle AOB = 7x^\circ

Line CD is a straight line, so \angle COD = 180^\circ

Also,

\angle COD = \angle COA+\angle AOB+\angle BOD = 180^\circ\\\Rightarrow 3x + 7x + 2x=180^\circ\\\Rightarrow 12x =180^\circ\\\Rightarrow x = \dfrac{180}{12}\\\Rightarrow x = 15^\circ

Hence, <em>answer</em> is x = 15^\circ.

Calculate the value of A to one decimal place
WINSTONCH [101]

Okay, you will need to use the law of cosines for this problem.

The Law of Cosines states (in this case): a^2 = b^2 + c^2 - 2 * b * c * cos A, where "a" is the side opposite angle A (7 inches), and b and c are the other two sides.

Plug the numbers in and you get: 7^2 = 5^2 + 9^2 - 2 * 5 * 9 * cos A, or:

49 = 25 + 81 - 90 * cos A.

Subtract (25 + 81) from both sides to get:

-57 = -90 * cos A.

Divide by -90 on both sides:

cos A = 19/30

To find A, you do the inverse trigonometric function to get:

cos^-1 of (19/30) = A.

I don't have a calculator that can do this right now, but if you plug the left side of the above equation into it (make sure it is in degrees, not radians), you should get A.

You need at least $100 to go to a BTS concert. You have $27 and your allowance is $10
REY [17]
Count by 10s after 27 so continue with 37, 47, 57 until you get past at least 100, which should be 8 times. Therefore it would take 8 weeks of allowance to reach $107
