Consider the figure.
Find the area of the composite figure to the nearest half unit. Use 3.14 for π

Answers

Answer:

23.5 cm^2

Step-by-step explanation:

First calculate the "rectangle" with the half-circle filled in

9*3 = 27

Then calculate the half-circle using the formula for the area of a circle [tex]\pi r^{2}[/tex], then dividing it by half

3.14 * 1.5 * 1.5 / 2 = 3.5325

Subtract the area of the half-circle from the area of the rectangle

27-3.5325

= 23.4675

= 23.5 (cor. to the nearest half unit)

The answer is 23.5 cm squared

Solve the following systems using the elimination method.

4x + 7y = 19
2x - y = -13

Answers

Answer: x = -4, y = 5

Step-by-step explanation:

[tex]$$Solve the following system: \\$\left\{\begin{array}{ll}7 y+4 x=19 & \text { (equation 1) } \\ -y+2 x=-13\end{array} \quad\right.$ (equation 2)\\\\Subtract $\frac{1}{2} \times($ equation 1) from equation 2 :\\$\left\{\begin{array}{l}4 x+7 y=19 \ \ \ \ (\text{equation 1}) \\ 0 x-\frac{9 y}{2}=-\frac{45}{2}\end{array}\right.$ (equation 2)\\\\Multiply equation 2 by $-\frac{2}{9}$ :\\[/tex]

[tex]\begin{cases}4 x+7 y=19 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Subtract $7 \times($ equation 2) from equation 1:\\$\begin{cases}4 x+0 y=-16 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2)\\ }\end{cases}$\\\\Divide equation 1 by 4 :\\$\begin{cases}x+0 y=-4 & \text { (equation 1) } \\ 0 x+y=5 & \text { (equation 2) }\end{cases}$\\\\Answer:\\$$\left\{\begin{array}{l}x=-4 \\y=5\end{array}\right.$$[/tex]

Answer: x = -4, y = 5

Step-by-Step Explanation:

=> 4x + 7y = 19 (Eq. 1)
=> 2x - y = -13 (Eq. 2)

We can multiply Eq. 2 by 7 in order to make the coefficients of ‘y’ same in both the equations thus being able to eliminate ‘y’ and find ‘x’

Therefore,
(2x - y = -13) * 7
=> 14x - 7y = -91 (Eq. 3)

On Adding Eq. 1 and 3, we get :-

18x = -72 (‘y’ gets Eliminated)
x = -72/18
=> x = -4

Therefore, x = -4

Substitute value of ‘x’ in Eq. 2 :-

2x - y = -13
2(-4) - y = -13
-8 - y = -13
-y = -13 + 8
-y = -5
=> y = 5

Therefore, y = 5

i didnt mean to click on the 31.50 but what is the answer ?

Answers

Answer:

D. $67.50

Step-by-step explanation:

A ticket costs $5.25, a drink costs $2.00, and a popcorn costs 4.00. Each person in the group buys all of these. So we know that each person is paying:

4.00 + 2.00 + 5.25 = 11.25

Since there are 6 people in the group we can multiply that by 6:

11.25 * 6 = 67.50

If you add all of them together you get 11.25
Then times it by 6 and that’s 67.5 then add the zero and that gets you 67.50 and that’s your answer
