Answer:

8.5

Step-by-step explanation:

area of a rhomus = (1/2)(product of its diagonals)

let the other diagonal be a

(1/2)(15a) = 60

15a= 120

a = 8

So let's find the hypotenuse of one of the right-angled triangles formed by the intersection of its diagonals

base = 4, height = 7.5

if h is the hypotenuse,

h^2 = 4^2 + 7.5^2

h = 8.5

Answer:

81%

Step-by-step explanation:

200-38= 162

162/200= 81/100

81%

Answer:

93%

Step-by-step explanation:

100 x 186= 200 * x

18600/200 = 200x/200

93%=x

186/200 = 0.93

convert decimal to percent

0.93 x 100= 93%

​

Answer: 43.2

Step-by-step explanation: 100% = 120pounds

36% = 120/100 × 36/1

Based on the histogram, the interquartile rangle of the distribution is 5 inches.

The interquartile range is the difference between the third quartile of a data set and the first quartile of the data set.

First quartile = 1/4 x ( n + 1)

= 101 / 4 = 25.25

25.25 on the histogram is 66

Third quartile = 3/4 x (n + 1)

303 / 4 = 75.75

75.75 on the histogram is 71

Interquartile range = 71 - 66 = 5

Answer:

To find the perimeter of this triangle, we add up all the sides together.

(8 · √3) + (8 · √3) + √384

But before we add them, let's simplify them.

(8 · 1.7) + (8 · 1.7) + 19.6

13.6 + 13.6 + 19.6

27.2 + 19.6

= 46.8, is the perimeter of this triangle.

Now to find the area, we use the formula:

(formula for area of a triangle)

A = BH · 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.

What we know:

Plug in the values into our formula:-

A = BH · 1/2

A = 13.6(13.6) · 1/2

A = 184.96 · 1/2

A = 184.96/2

A = 92.48, is the area for this triangle.

Answer:

x=-96

Step-by-step explanation:

isolate x by moving -124x to the other side by adding -124x to -126x = -2x

then it will look like: 102= -2x-90

add 90 to both sides: 192= -2x

divide both sides by -2 to isolate x

x= -96

Answer:

The answer is A.

Step-by-step explanation:

Option B has y-int: (0,-5)
Option C has y-int: (0,5)

Option D has x-int(5,0)

Answer:

x = 15

Step-by-step explanation:

the 2 angles are a linear pair and sum to 180° that is

8x - 3 + 4x + 3 = 180

12x = 180 ( divide both sides by 12 )

x = 15

The angles are supplementary angles. Then the value of the variable 'x' will be 15.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angles are 8x - 3 and 4x + 3. And they are supplementary angles. Then the equation is given as,

8x - 3 + 4x + 3 = 180

Simplify the equation, then we have

8x - 3 + 4x + 3 = 180

12x + 0 = 180

x = 15

The angles are supplementary angles. Then the value of the variable 'x' will be 15.

Answer:

Below!

Step-by-step explanation:

Since the "y" variable is on the L.H.S, we can rewrite y = 5 in slope intercept form to determine the slope and the y-intercept.

Now, let's compare the equation of the line with the formula.

Thus, we will obtain the following equations:

============================

Thus, the slope is 0 and the y-intercept is 5. Since the slope is 0, the line will be a horizontal line that intersects the y-intercept.

In this case, the y-intercept is 5. Thus, the line will be a horizontal line, intersecting the y-intercept (5). (Refer to graph).
