Answer:

Step-by-step explanation:

Lets start by labeling the triangle. Lets say the height is x and the base is x-16.

Next, we know the area of the triangle is 96, so we should make an equation. The area (96) of a triangle is (b*h)/2. So lets substitute.

96=[(x-16)*x]/2

Now, we should simplify the equation. Let us start by moving the /2 to the other side and making it *2.

192=(x-16)*x

Open parenthesis and get

192=x^2-16x

simplify and get

x=24

x is the height so the base must be x-16.

base=8, height=24

Can we conclude that these two triangles are congruent?

Aleonysh [2.5K]

Answer:

Yes,

Step-by-step explanation:

because two sides are shown equal to each other, a and b. Also two angles are equal to each other, x and y. Once you know two angles or two sides are equal so is the third side.

Another way is SAS (side angle side). There is side a, angle y, and side b. These are shown on both triangles.

Therefore, we can conclude these two triangles are congruent.

Answer:

B. 7y - 15

Step-by-step explanation:

Simplifying

10y + -3(y + 5) = 0

Reorder the terms:

10y + -3(5 + y) = 0

10y + (5 * -3 + y * -3) = 0

10y + (-15 + -3y) = 0

Reorder the terms:

-15 + 10y + -3y = 0

Combine like terms: 10y + -3y = 7y

-15 + 7y = 0

Solving

-15 + 7y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + 7y = 0 + 15

Combine like terms: -15 + 15 = 0

0 + 7y = 0 + 15

7y = 0 + 15

Combine like terms: 0 + 15 = 15

7y = 15

Divide each side by '7'.

y = 2.142857143

Simplifying

y = 2.142857143

Plot A shows the number of hours ten girls watched television over a one-week period. Plot B shows the number of hours ten boys

ziro4ka [17]

The true statement is both the mean and median are greater for Plot A than for Plot B..

<h3>What is the true statement?</h3>

Mean is the average of a data set. Median is the number at the center of a dataset arranged in either ascending or descending order.

Mean for plot A = (3 + 4 + 4 + 5 + 5 + 6 + 6 + 7 + 7 + 10) / 10 = 5.7

Median for plot A = (5 + 6) / 2 = 5.5

Mean for plot B = (3 + 4 + 4 + 5 + 5 + 5 + 6 + 6 + 6 + 7) / 10 = 5.1

Median for plot B = 5

Which of these points lie on the circumference of the circle X^2 + Y^2 = 25? Circle your answer. (-3, 4) (6.25, 6.25) (9, 16) (-

Bad White [126]

Answer:

A. (-2, 4)

Step-by-step explanation:

<u>Given the circle:</u>

$x^2+y^2=25$

$x^2+y^2=5^2$

According to the equation, any point with one of the coordinate > 5 lies outside of the circle since the radius is 5 units.

The points 2, 3 and 4 have at least one of the coordinates greater than 5.

<u>Let's verify the point 1:</u>

$(-3)^2+4^2=9+16=25\\$
$25=25$
