Answer:
The area of trapezoid is 39.6cm²
Step-by-step explanation:
Given that the formula of area of trapezoid is A = 1/2×(a+b)×h where a and b is the length and h is the height. So you have to substitute the values into the formula :
[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]
[tex]let \: a \: = 8.9 \\ let \: b \: = 5.5 \\ let \: h \: = 5.5[/tex]
[tex]area = \frac{1}{2} \times (8.9 + 5.5) \times 5.5[/tex]
[tex]area = \frac{1}{2} \times 14.4 \times 5.5[/tex]
[tex]area = \frac{1}{2} \times 79.2[/tex]
[tex]area = 39.6 {cm}^{2} [/tex]
Answer: The area is 39.6
Step-by-step explanation:
First multiply 5.5×5.5= 30.25
Then subtract 8.9 - 5.5=3.4
Then multiply 5.5 x 3.4=18.7
Divide 18.7/2=9.35
Add 30.25 + 9.35 =39.6

Find the domain of the function.
y = 5[tex]\sqrt{x}[/tex]
Answer:
[0, infinity)
Step-by-step explanation:
The domain is including all numbers from 0 to infinity.
The reason negative numbers are not included is because of the [tex]\sqrt{x}[/tex]. A negative number cannot be included there, otherwise it would be what's called an "imaginary number" (i).
Therefore, every number besides negative numbers are included in the domain.

Mike can plow a field in 12 hours and his brother Phil can plow it in 15 hours. How long will it take them to plow it if they use two plows and work together?
Answer:
6.66 hours, that is, 6 hours and 40 minutes.
Step-by-step explanation:
If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.
If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.
So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:
(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66
So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.

Answer:
Step-by-step explanation:
radius of the circle=12 cm / 2=6 cm
Area of the square=side²=(12 cm)²=144 cm²
Area of the circle=πr²=(3.142)(6 cm)²≈(3.142)*36 cm²≈113.112 cm²
Area of the four sides between the square and the circle=
=Area of the square - area of the circle=144 cm²-113.112 cm²=30.888 cm²
shaded area =30.888 cm²/4=7.722 cm²

Rename 3/4 and 9/10 using the least common denominator.
Answer:
15/20 and 18/20
Step-by-step explanation:
Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10
multiples of 4: 4, 8, 12, 16, 20
multiples of 10: 10, 20
Least common denominator = 20
Rewrite fractions: 15/20 and 18/20
3/4 and 9/10 using the least common denominator is 15/20 and 18/20.
What is LCM?LCM of two or more than two given numbers is the smallest common multiple that is divisible by two or more than two given numbers.
Given, are two fractions 3/4 and 9/10 we know the LCM of 4 and 10 is 20.
∴ (3×5)/(4×5) and (9×2)/(10×2). (we have to multiply same constant to the
fraction to retain it's original value).
So, 3/4 and 9/10 using the least common denominator is 15/20 and 18/20.
