Answer:

Step-by-step explanation:

The figure is a combination of a triangle and a rectangle

Area of rectangle = bh = 15(5) = 75

We have no way of finding the height of the triangle, unless there is some information that I don't see with regard to the figure.

If the coordinates of the endpoints of a diameter of the circle are known, the equation of a circle can be

miskamm [114]

The equation of the circle would be (x - 1)² + (y - 3)² = 65.

<h3>What is the equation of a circle?</h3>

The equation of a circle with center (h,k) and radius, r in center radius form is given;

(x - h)² + (y - k)² = r²

The coordinates of the center of the circle can be calculated by the formula

((x₁ + x₂)/2, (y₁ + y₂)/2).

The point (x₁,y₁) = (9, 2) and (x₂,y₂) = (-7, 4).

So, ((9 -7)/2, (4 + 2)/2) = (1, 3).

Now, r² = (x₂ - x₁)² + (y₂ - y₁)².

Let (x₁, y₁) = (1, 3) and (x₂, y₂) = (-7, 4).

So, r² = (-7 -1)² + (4 - 3)²

= -8² + 1² = 64 + 1 = 65.

With center (h,k) = (1, 3) and r² = 65, we have

Thus, the equation would be (x - 1)² + (y - 3)² = 65.

In a certain class 40% of students are girls and 20% of the girls wear glasses what percent of the children in the class a girl

Zielflug [23.3K]

Okay.
40/100 students are girls.
20% of those 40 girls wear glasses.
So that's 20/40.
20/100

At East Middle School, there are 585858 left-handed students and 609609609 right-handed students. The numbers of left- and right

lisabon 2012 [21]

Answer: C. Left-handed: 48 Right-handed: 504

E. Left-handed: 30 Right-handed: 315

Step-by-step explanation:

Here is the completed question:

At East Middle School, there are 58 left-handed students and 609 right-handed students. The numbers of left- and right-handed students at West Junior High are proportional to the numbers at East Middle School. Which of the following could be the numbers of left-handed and right-handed students at West Junior High?

A. Left-handed: 42 Right-handed: 483

B. Left-handed: 28 Right-handed: 378

C. Left-handed: 48 Right-handed: 504

D. Left-handed: 56 Right-handed: 560

E. Left-handed: 30 Right-handed: 315

Since it's direct proportion, we have to calculate the constant of proportionality which will simply be:

= 609 / 58 = 10.5

A. Left-handed: 42 Right-handed: 483

Constant = 483/42 = 11.5

Incorrect

B. Left-handed: 28 Right-handed: 378

Constant = 378/28 = 13.5

Incorrect

C. Left-handed: 48 Right-handed: 504

Constant = 504/48 = 10.5

Correct

D. Left-handed: 56 Right-handed: 560

Constant = 560/56 = 10

Incorrect

E. Left-handed: 30 Right-handed: 315

Constant = 315/30 = 10.5

Correct

Therefore, the correct options are C and E.

Please help! It’s due tomorrow it also says to show my work

Given:

The inequality is

$x+19\leq 23$

To find:

The value of x and then graph on the number line.

Solution:

We have,

$x+19\leq 23$

Subtracting 19 from both sides, we get

$x+19-19\leq 23-19$

$x\leq 4$

It means all the real values of x which are less than or equal to 4 are in the solution set. So, an arrow approaches towards left from x=4 as shown in the below figure.
