Answer:
70
Step-by-step explanation:
You add all the numbers together and then divided by the number of numbers so
90+80+60+50=
280 divided by 4 is 70
Answer:
The fencing will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of what comes out 1 foot of fence
45.53 * $7.25 = 330.0925
Round to the nearest hundredth
$330.0925 = $330.09
Answer:
2261.94671
Step-by-step explanation:
You must first find the circumference of the track. Using 2(pi)r.
Where pi=3.14... and r=radius
you can find the radius by dividing the diameter by 2, 120/2=60
Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515
Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671
NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377
Hello! So, for the first inequality, we have to add 10 to both sides. When you do that, 3.5x > 7. Then, you have to divide both sides by 3.5. When you do that, you get x > 2. Then, for the second inequality, you have to add 9 to both sides, then you would get 8x < 48. Divide both sides by 8 and you get x < 6. The compound inequality for this question would be 2 < x < 6.
Answer:
<h2>y = -9x - 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em> - slope
<em>b</em> - y-intercept (0, b)
We have the slope <em>m = -9</em> and the y-intercept (0, -2) → <em>b = -2</em>.
Substitute:
<em>y = -9x + (-2) = -9x - 2</em>
