Answer: 5/24

Step-by-step explanation:

The problem is 7/12-3/8. I got a common denominator of 24, then multipled 8 and 3 by 3, and 7 and 12 by 2. The problem is now 14/25-9/24, which equals 5/24

The endpoints of a diameter of a circle are A(3,1) and B(9,9). Find the area of the circle in terms of pie

andrey2020 [161]

Answer:

The answer is $25\pi$ units squared.

Step-by-step explanation:

If we find the diameter, we can find the radius by halving the diameter.

We can find the diameter by using the endpoints of the diameter.

The distance formula will give us the length between (3,1) and (9,9).

The distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

The distance between the $x$ 's is 9-3=6.

The distance between the $y$ 's is 9-1=8.

The distance between the points is given by $\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10$ .

The radius is therefore $\frac{10}{2}=5$ .

We are asked to find the area of this circle.

The formula for finding the area of a circle is $\pi r^2$ .

Since the radius is $5$ , then the area in terms of $\pi$ ,(pi), is $\pi (5)^2=\pi (25)$ .

The answer is $25\pi$ units squared.

Easy question i will mark braineliest

Yuki888 [10]

Answer:

Step-by-step explanation:

$5(y - 3.8) = 4.7(y - 4)$

Distribute 5 through the parentheses

$5y - 19 = 4.7(y - 4)$

Distribute 4.7 through the parentheses

$5y - 19 = 4.7y - 18.8$

Move ' 4.7 y ' to L.H.S and change it's sign

$5y - 4.7y - 19 = - 18.8$

Move constant to R.H.S and change it's sign

$5y - 4.7y = - 18.8 + 19$

Collect like terms

$0.3y = - 18.8 + 19$

Calculate

$0.3y = 0.2$

Divide both sides of the equation by 0.3

$\frac{0.3y}{0.3} = \frac{0.2}{0.3}$

Calculate

$y = 0.67$

Hope this helps...

Best regards!!

Write an equation which is perpendicular to the line of y= -5/2x+2

S_A_V [24]

Answer:

y = 2/5x

Step-by-step explanation:

Perpendicular lines are lines which have negative reciprocal slopes of each other.

The line y = -5/2 x + 2 has slope -5/2. Therefore its perpendicular slope will be 2/5.

The equation can cross anywhere on the y-axis for its y-intercept since no specific point is given. Here I chose (0,0).

y = 2/5x
