Answer:

Height of the painting is 30 inches.

Step-by-step explanation:

If the rectangular frame of a painting is in the shape of ABCD.

Measure of frame's diagonal AC is 50 inches and it forms an angle of 36.87° angle with the bottom of the frame BC.

Now we have to determine the height of the painting.

Sin(36.87)° = \frac{AB}{AC}

0.60 = \frac{x}{50}

x = 50×0.6

x = 30 inches

Therefore, height of the painting is 30 inches.

The sum of three numbers is 11. the first number minus the second plus the third is 5. the first minus the third is 1 more than
Anestetic [448]
X+y+z=11, x-y+z=5, x-z=y+1 and solve it by any of the methods: isolation, elimination or determinants. isolation (or back substitution, would be for instance: z = 11-x-y, z=5-x+y, z = x-y-1 and then impose z=z:
11-x-y=5-x+y,
11-x-y=x-y-1,

The first takes you to: 6=2y or y=3, then the second to 12=2x or x=6, so that:

x=6, y=3, z=2.

You can see that it checks out

Find the Area of the figure below, composed of a parallelogram and one
sukhopar [10]

Answer:

300.5 = 300

Step-by-step explanation:

area= base x height (parallelogram)

area= \frac{\pi r^2}{2} (semicircle)

parallelogram: 11 x 20 = 220

semicircle: \left[\begin{\frac{22(8^2)}{7}}\right] \frac{1}{2}

=> \frac{1408}{14}\\

=> 100.5

therefore 100.5 + 220 = 300.5-ans.

Answer:

A is the correct answer

Step-by-step explanation:

Given: Table of x and y

x : 2 4 6 8

y : 3 4 5 6

Using two point find the slope:

(2,3) and (4,4)

Now we find slope using last two point

(6,5) and (8,6)

Slope is equal. Thus, The given relation is linear.

Hence, The relation represents a linear equation
