find the height of a trapezium if the sum of the lengths of the parallel sides is 39cm and whose area is 234cm²​

Answers

Answer 1

Answer:

the answer according to my calculations will be 12

Step-by-step explanation:

the formula of area of trapezium is A=a+b÷2×h

and if we wanna solve for h

h=2 A÷ a+b

h=2 (234)÷39

after calculations...

h= 12  

hope it helps:)

Answer 2

Answer:

h = 12 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h ( sum of parallel bases )

Here A = 234 and sum of bases = 39 , then

[tex]\frac{1}{2}[/tex] h × 39 = 234 ( divide both sides by 39 )

[tex]\frac{1}{2}[/tex] h = 6 ( multiply both sides by 2 to clear the fraction )

h = 12

Find the number of grams of protein in an 8-ounce serving of vanilla yogurt that contains 179 calories, 3 g of fat, and 31 g of carbohydrate.
g

Answers

Answer:

7 grams of protein

Step-by-step explanation:

C = 9f + 4p + 4c

Plug the given information into the given formula

179 = 9(3) + 4p + 4(31)

Use PEMDAS

179 = 27 + 4p + 124

Combine like terms

179 = 151 + 4p

Subtract both sides by 151 to isolate variable p

179 - 151 = 4p

28 = 4p

Divide both sides by 4 to isolate variable p

28 ÷ 4 = p

7 = p

Which number line shows the solution to inequality 3x – 3 < 12?

Answers

Answer:

A

Step-by-step explanation:

The Graph "A" show the value of x in  inequality 3x – 3 < 12

What is inequality?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

What does open circle and close circle shows in graph?

A closed circle indicates "greater than or equal to" or "less than or equal to," while and open circle indicates "greater than" or "less than".

According to the question

Given inequality 3x – 3 < 12

Solving for x

3x – 3 < 12

3x < 12 + 3

3x < 15

x < 5

Open circle will be used to show the greater than sign

Therefore,

Graph  A shows the inequality .

Hence, the Graph "A" show the value of x in  inequality 3x – 3 < 12
