Step-by-step explanation:
Break down the figure into a circle of diameter 7 and an 11 by 7 rectangle.
Area of circle = π3.5² = 12.25π ≈ 38.48 square meters
Area of rectangle = 11*7 = 77 square meters
Total area = 38.48+77 = 115.48 square meters
a race car is driving under the caution flag at 440 feet per second begins to accelerate at a constant rate after the warning flag. the distance traveled since the warning flag in feet is characterized by 30t^2+440t, where t is the time in seconds after the car starts accelerating again. How long will the car take to travel 150 feet?
Answer: [tex]\frac{1}{3}\ s[/tex]
Step-by-step explanation:
Given
Distance traveled is [tex]s=30t^2+440t[/tex]
for s=150 ft
[tex]\Rightarrow 30t^2+440t=150[/tex]
[tex]\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s[/tex]

Step-by-step explanation:
Ella buys eggs and apples at the store.
She pays a total of $44.35.
She pays a total of $2.95 for the eggs.
She buys 6 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of apples costs.
Answer:
6.9
Step-by-step explanation:
The total payment was 44.35 and Ella bought 6 bags of apples and eggs
eggs cost 2.95 so apples cost 44.35-2.95=41.4
lets call bags "x"
so
6x=41.4 (price)
divide both by 6
x=6.9

Answer:
4. 300 5. 7 6. 2
Step-by-step explanation:
In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:
[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]
We would then cross multiply in order to find the value of x. Like this:
60 × 5 = 300
1 × x = 1x
300 = 1x
300 = x
So now we know that x is 300.
We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:
[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]
8 × x = 8x
2 × 28 = 56
8x = 56
÷8 ÷8
x = 7
We now know that x is 7.
Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

Angela wants to use a one-sample zzz interval to estimate what proportion of employees at her large corporation are satisfied with their benefits. She plans on using a confidence level of 90\%90%90, percent, and she wants her margin of error to be no more than \pm 5\%±5%plus minus, 5, percent.
Answer:
Step-by-step explanation:
It's 271 on Khan Academy
The sample space size that Angela wants to use for the employees who are satisfied with their benefits is. 271
What is margin of error?In statistics, the margin of error is the level of inaccuracy in the findings of surveys using random samples. Less reliance on survey or poll results is indicated by higher statistical margins of error.
Given that,
[tex]\^p[/tex] = 0.5
1 - [tex]\^p[/tex] = 1 - 0.5= 0.5
margin of error = E = 5% = 0.05
At 90% confidence level
= 1 - 0.90 = 0.10
0.10/2 =0.05
Z/2 = 1.645 ( Using z table )
Sample size = n = (Z/2 / E)² x (1 - [tex]\^p[/tex])²
= (1.645 / 0.05)² * 0.5 x 0.5
=270.6
Sample size = 271
The required sample size is 271.

Solve the system of linear equations by elimination -x+y=4;x+3y=4
Answer:
the solution is (-8, 4)
Step-by-step explanation:
Let's use the addition/subtraction method here to eliminate one variable:
-x+y=4
x+3y=4
Combining these two equations results in
4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:
x + 3(2) = 4, or x = -2.
Then the solution is (-8, 4)
