How do you solve for X and round the nearest tenth

Answer:

x = 7.3

Step-by-step explanation:

When solving for missing sides using angles, use trig functions.

We have the angle 63° to use.

We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.

Cos T = (adjacent side)/(hypotenuse)

Here we know 'T' and the hypotenuse, so plug them in and solve

Cos 63° = x/16

(16)Cos 63° = x (multiply both sides by 16 to isolate 'x')

7.263847996 = x (use your calculator to solve the left side)

7.3 = x (rounded to the nearest 10th)

Find the area of the circle.. PLEASE HELP

Leno4ka [110]

Answer:

The area is 154 cm²

Step-by-step explanation:

Since the formula for the area of a circle is pi times the radius squared, divide the diameter in half to get the radius (7). Then, square the radius (49). Next, multiply that by pi (153.938). After that round to the nearest whole number (154). Hope that helps!

Find the approximate side length of a square game board with an area of 105 in2.

aleksley [76]

Answer:

Rounded to the nearest inch: 10

Rounded to the nearest tenth: 10.2

Rounded to the nearest hundredth: 10.25

Step-by-step explanation:

To find the area of a square, we multiply the side length by itself, or in other words, SQUARE the side length!

$A=s^2$

We are given the area, so plugging that into our equation looks like this:

$105=s^2$

To eliminate the exponent, take the square root of both sides of the equation!

$\sqrt{105}=s$

From here, there are a few paths to take, depending on what your teacher is looking for. I will evaluate the approximate of the square root by finding the nearest perfect squares.

The nearest perfect square less than √105 is √100, and the nearest perfect square greater than √105 is √121.

105 is closer to 100 than to 121, so √105 is closer to √100.

√100 is equal to 10, so the √105 is approximately 10 inches!

Using a calculator to check:

$\sqrt{105}=10.247$ inches

WORTH 50 POINTS graph y=4/7x−2. i need two points

Pachacha [2.7K]

Cant really show you how to do it but the graph would start at the y axis at (0,-2) then from there each point would move to the left 4 and up 7 or back 4 and down 7. It would form a straight line.

A grocery store sells 5 bottles of water for $3 and 15 bottles of water for$8 is the cost of the water proportional to the numbe

egoroff_w [7]

Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
