Answer: 1 3/4 × 1 1/2
Step-by-step explanation:
Since Harry needs 1 3/4 cups of flour for one batch of cookies, but he wants to make 1 1/2 batches, the equation that can be used to find how many cups of flour Harry will need will be:
= (1 3/4 / 1) × 1 1/2
= 1 3/4 × 1 1/2
Therefore, to make 1 1/2 batches, the cups of flour needed will be:
= 1 3/4 × 1 1/2
= 7/4 × 3/2
= 21/8
= 2 5/8 cups of flours.
Step-by-step explanation:
b + 81° = 117° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
b = 117° - 81°
b = 36°
for no. 14
The angles that are congruent to < 1 are < 4 and < 8.

The value of 8⁴ is 8 * 8 * 8 * 8 = 4,096 CHOICE C.
Prime factorization of 1,260
1260 ÷ 2 = 630
630 ÷ 2 = 315
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
2 x 2 x 3 x 3 x 5 x 7 CHOICE D.
Composite numbers are numbers that have more factors other than 1 and itself.
91 / 1 = 91
91 / 7 = 13 CHOICE C. 91 is a composite number.
We want to clear the fractions by multiplying both sides of the equation by the LCD of all the fractions in the equation. Find the least common denominator of all the fractions in the equation.
