Q 1

Sum of interior angles of a pentagon:

4x + 60 = 180(5 - 2)4x + 60 = 5404x = 480x = 120Q 6

Midsegment is half of the sum of the bases:

(2n - 2 + 4n + 6)/2 = n + 12(6n + 4)/2 = n + 123n + 2 = n + 122n = 10n = 5

Midsegment is:

5 + 12 = 17

Correct choice is D

Q 3m∠1 = 90 as diagonals are perpendicularm∠2 = 41 as alternate interior angles

∠3 is complementary with ∠2:

m∠3 = 90 - 41 = 49

None of the choices is correct

In which 3 statements below will the number 24 correctly fill in the blank? A) 2 feet = ___ inches B) 24,000 grams = ___ kg C) 3 gallons = ___ pints D) ___ pints = 12 cups E) 240 mg = ___ grams

Answers

Answer:

A,B and C.

Step-by-step explanation:

(A) 1 feet = 12 inches

So, 2 feet = 2 × 12 inches = 24 inches

(B) 1,000 grams = 1kg

So, 24,000 grams = (24,000÷ 1,000) = 24kg

(C) 1 gallon = 8 pints

So, 3 gallons = 3 × 8 pints = 24 pints

(D) 1 pints = 2 cups

So, 12 cups = (12÷ 2) = 6 pints

(E) 1 gram = 1000 mg

So, 240 mg = (240 ÷ 1,000) = 0.24 gram

Hence, A,B and C correctly fill with 24.

in a test, a hybrid car drove 4952 yards on 1 cup of gasoline. What is this rate in miles per gallon ?

Answers

Answer:45

Step-by-step explanation: There’s 16 cups in a gallon and the car goes 4952 yards per cup. You have to multiply the equivalency of a gallon by the yards to get your total distance in yards. Then, you would have to divide your total in yards (79,232) by the yards in a mile (1760). Your ratio would be around 45 miles per gallon.

At the craft store, Janice bought a bag of green and yellow marbles. She received 14 green marbles and 11 yellow marbles. What percentage of the marbles were green?

Answers

Answer: 56%

Step-by-step explanation:

Since Janice bought a bag of green and yellow marbles and she received 14 green marbles and 11 yellow marbles, the total number of marbles will be:

= 14 + 11 = 25 marbles

Number of Yellow marbles = 11

Number of Green marbles = 14

Total number of marbles = 25

The percentage of the marbles that were green will be:

= Number of Green marbles / Total marbles × 100

= 14/25 × 100

= 14 × 4

= 56%
