Which of the following is the area of a trapezoid whose dimensions are base one = 10 cm, base two = 5 cm, and height = 2 cm?30 squared cm


30 cm


15 cm


15 squared cm

Answers

Answer 1
Answer:

Answer:

The correct answer is D. 15 squared centimeters.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Base one = 10 centimeters

Base two = 5 centimeters

Height = 2 centimeters

2. Let's find out the area of the trapezoid, using the following formula:

Area = 1/2 (Base one + Base two) * Height

Replacing with real values:

Area = 1/2 (10 + 5) * 2

Area = 1/2 (15 * 2) = 1/2 (30)

Area = 15 centimeters ²

The correct answer is D. 15 squared centimeters.

a skate shop owner ordered 60 skateboards from the manufacturer. out of the 60 boards that were ordered, 18 were longboard. he wants to know what percent of his order was longboards?

Answers

The percentage of the skateboards that were longboards is 30%.

Number of skateboards ordered = 60

Number of skateboards that were longboards = 18

Therefore, the percentage of the skateboards that were longboards will be:

= 18/60 × 100

= 30%

Therefore, the percentage of the skateboards that were longboards is 30%.

4 √(40) + 7 √(160)
​

Answers

Answer:

Step-by-step explanation:

44√(40) + 7 √(160) = 4√(2*2*2*5)  + 7√(4*4*5*2)\n  = 4*2√(10)  + 7*4√(10)\n = 8√(10) + 28√(10) \n

= (8 + 28)√10

= 36√10

Answer:

36√(10)

Step-by-step explanation:

Using the rule of radicals

√(a) × √(b) ⇔ √(ab)

Simplifying the radicals in the expression

√(40)

= √(4(10))

= √(4) × √(10) = 2√(10)

√(160)

= √(16(10))

= √(16) × √(10) = 4√(10)

Thus

4√(40) + 7√(160)

= 4 × 2√(10) + 7 × 4√(10)

= 8√(10) + 28√(10)

= 36√(10)

Jason wrote the mixed number 1 1/3 as the sum of three fractions. None of the fractions had a denominator of 3. How is this possible? What fractions might jason have used?

Answers

The required sum of the fractions whose sums result 1 1/3 are 2 / 6 + 1 / 2 + 1/2.

Given that,
Jason wrote the mixed number 1 1/3 as the sum of three fractions. None of the fractions had a denominator of 3. What fractions might jason have used is to be determined,

What is the fraction?

Fraction is defined as the number of compositions that constitute the Whole.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.


here,
we simplified the terms in mixed fraction 1 1 /3 as,
1 = 1/2 +1/2 and 1/3 = 2 / 6
So
1 1/3 = 1 /2 +1 / 2 +2 / 6

Thus, the required sum of the fractions whose sums result 1 1/3 are 2 / 6 + 1 / 2 + 1/2.
