Exact Area = 25pi square units
Approximate Area = 78.5 square units
The approximate value is found using pi = 3.14
====================================================
Explanation:
I think you meant to say "quarter circle" instead of "semicircle".
The area of a full circle with radius r = 10 is
A = pi*r^2
A = pi*10^2
A = pi*100
A = 100pi
But we only want one quarter of this. So we divide the full area by 4
(100pi)/4 = (100/4)pi = 25pi
The exact area in terms of pi is 25pi square units
If we used the approximation pi = 3.14, then we can say 25*pi = 25*3.14 = 78.5 is the approximate area
To get a better approximation, use more decimal digits in pi.

Answer:
23%
Step-by-step explanation:
322 ÷ 1400 = 0.23 = 23%
Step-by-step explanation:
x percent of 1400 calories = 322 calories so, (x × 1400)÷100 = 322x = (322 × 100) ÷1400x = 32200 ÷ 1400x = 23MARK ME AS BRAINLISTPLZ FOLLOW MESolve x, show work. what equation would i need to use

factor 11k^4 − 88k^3 + 77k^2
Answers
Answer:
11k^2 (k - 7)(k - 1)
Step-by-step explanation:
The highest common factor is
11k^2
Using the distributive property we get at least 2 factors.
11k^2 ( k^2 - 8k + 7)
The second factor reduces yet again.
11k^2 (k - 7)(k - 1)
Answer:
11k^2(k−7)(k−1)
Step-by-step explanation:
11k^4 − 88k^3 + 77k^2
Factor out 11.
11(k^4-8k^3+7k^2)
Consider k^4-8k^3+7k^2. Factor out k^2.
k^2(k^2−8k+7)
Consider k^2 −8k+7. Factor the expression by grouping. First, the expression needs to be rewritten as k^2+ak+bk+7. To find a and b, set up a system to be solved.
a+b=−8
ab=1×7=7
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. The only such pair is the system solution.
a=−7
b=−1
Rewrite k^2−8k+7 as (k^2−7k)+(−k+7).
(k^2−7k)+(−k+7)
Factor out k in the first and −1 in the second group.
k(k−7)−(k−7)
Factor out common term k−7 by using distributive property.
(k−7)(k−1)
Rewrite the complete factored expression.
11k^2(k−7)(k−1)

Is 14,48,50 a Pythagorean triplet
Step by step explanation please
Answers
Answer:
yes
Step-by-step explanation:
If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2
largest value = 50 ⇒ 50² = 2500
14² + 48² = 196 + 2304 = 2500
Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet

Kira drove 522 miles in 9 hours.
At the same rate, how many miles would she drive in 7 hours?
Answers
GIven:522 miles in 9 hours.
So if we divide 522 by 9 we get that Kira drives 58 miles per hour.
Now in 7 hours Kira just drives 7 times that which means Kira drives.
58*7=406 miles
Hope this helped!
Step-by-step explanation:
Distance travelled in 9 hours = 522 miles
Distance travelled in 1 hour = 522/9 = 58 miles
Distance travelled in 7 hours = 7 * 58 = 406 miles

A parking lot has the shape of a parallelogram. The length of two adjacent sides are 70 meters and 100 meters. The angle between them is 70°. What is the area of the parking lot?
Answers
The area of the parking lot is 4606 square meter.
What is parallelogram?
It is a special type of quadrilateral that has both the pairs of opposite sides parallel and equal.
What is the area of parallelogram?
The area of a parallelogram is the product of its base and height.
We have,
length of two adjacent sides are 70meters and 100meters.
And base of parallelogram is 70m. (length of parallelogram is its base)
Angle between the adjacent sides is 70 degrees.
Let, side AB and BC be the two adjacent sides whose lengths are 70m and 100m.And h be the height of the parallelogram.
For the height of the parallelogram
In ΔADE, we have
[tex]sin70=\frac{DE}{AD}[/tex] [tex](sinx=\frac{perpendicular}{hypotenuse})[/tex]
⇒ [tex]0.9397=\frac{h}{70}[/tex]
⇒ [tex]0.9397[/tex]×70[tex]=h[/tex]
⇒ h=65.8m
Formula to find the area of parallelogram:
Area= base× height
so, the area of parking lot=base × height
substitute the value of base and height of the parallelogram in the above formula.
Therefore,
[tex]Area=65.8[/tex]×[tex]70[/tex]
[tex]Area=4606m^{2}[/tex]
Hence, the area of the parking lot is 4606 square meter.
