Answer:
19x-19+23y
Step-by-step explanation:
add the like terms
The area of a circle is <span>πr²
the outer circle area = </span><span>π 4x²
the inside circle area = </span>π.6²=36<span>π
</span>the outer circle area - <span>the inside circle area = </span><span>he shaded region
</span>π 4x² - 36π =<span>220π cm2 it implies x²-9 =55 and x²=64, and x =sqrt(64)=8
the value of x is 8</span>
Answer:
$2.5
Step-by-step explanation:
Number of pounds of banana needed = 5 pounds
Cost per pound of banana = 0.50
To solve using place value blocks :
Ignoring the decimal in the cost per pound:
We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.
5 * 5 = $25
Now we can add the one decimal point (in the cost per pound) to our result
Then we have $2.5
Hence, total cost = $2.5
You take $1472 and divide it by 4
$1472 divided by 4 = $368 per week or $52.57 a day
hope this helps!!

is a right triangle with base length 1 and height 8, so the area of

is

.
The average value of

over

is given by the ratio

The denominator is just the area of

, which we already know. The average value is then simplified to

In the

-plane, we can describe the region

as all points

that lie between the lines

and

(the lines which coincide with the triangle's base and hypotenuse, respectively), taking

. So, the integral is given by, and evaluates to,
