Answer:
151,334.2263
Step-by-step explanation:
7.3 to the 6th power
Let
x-----------> the length of the rectangular corral
y-----------> the width of the rectangular corral
we know that
the area of the rectangular corral is equal to
so
-------> inequality A
the perimeter of the rectangular corral is equal to
so
-----> inequality B
using a graphing tool --------> resolve the compound system inequalities
see the attached figure
the solution is the shaded area
so
the length of 650 feet does meet the requirements of the runners corral
and the width is 64 ft-------> see the graph
<u>the answer is</u>
a) the length of 650 feet does meet the requirements of the runners corral
V≈254.47
Which rounded to the nearest tenths place, is 254.5
The equation to find the volume of a cylinder is V=πr^2h, so if we input 3 into where r is, and if we input 9 in the place of h, we get V=π(3^2)9
If we solve the exponent, now it’s V=(π9)9. So now we multiply pi by 9, then that by 9, and you get 254.47
You need to make a proportion. Cross multiply and divide.
eggs 2 x
cookies 4 10
(2)(10) = 4x
20 = 4x
x = 5
You will need 5 eggs to make 10 dozen cookies
Answer:
2x - 0.4x ;
8x/5 ;
Yes
Step-by-step explanation:
Let number of miles = x
Arlene:
Double number of miles = 2 * x = 2x
Subtract 20% of the result :
2x - 20% of 2x ;
2x - 0.4x
Raul:
Divides Number of miles by 5 ; x / 5
Multiplies result by 8 ;
8 * (x/5) = 8x /5
To know if expressions are equivalent :
Let x = 10 miles
Using Arlene's expression:
2x - 0.4x
x = 10
2(10) - 0.4(10) = 16
Using Raul's expression :
8x / 5
(8*10) / 5
80/5
= 16
Since they give the same result, we can conclude that the expression are equivalent
