Little Snail is going to visit his friend over at the next pond, 3 miles away. He can crawl ( 1/2. 1/3, 1/4, 3/4, 2/3 ) of a mil

KIM [24]

Solution :

It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.

When the snail crawls 1/2 of a mile per day, it will take him, $1 \times \frac{2}{1} \times 3$

= 6 days to get to the next pond.

When the snail crawls 1/3 of a mile per day, it will take him, $1 \times \frac{3}{1} \times 3$

= 9 days to get to the next pond.

When the snail crawls 1/4 of a mile per day, it will take him, $1 \times \frac{4}{1} \times 3$

= 12 days to get to the next pond.

When the snail crawls 3/4 of a mile per day, it will take him, $1 \times \frac{4}{3} \times 3$

= 4 days to get to the next pond.

When the snail crawls 2/3 of a mile per day, it will take him, $1 \times \frac{3}{2} \times 3$

= 4.5 days to get to the next pond.

In circle T, PTQ = RTS. What is the measure of PQ? 24° 33° 48° 66°

weqwewe [10]

Answer:

The correct option is D

66°

Step-by-step explanation:

Given that ∠PTQ ≅ ∠RTS

The measure of the arc SR = 66°

So ∠RTS = 66°

But also, ∠PTQ ≅ ∠RTS

Therefore ∠PTQ = 66°

and the measure of the arc PQ = ∠PTQ

Therefore, measure of the arc PQ is 66°.

In a class of 20 students, 40% are boys. Twenty-ﬁve percent of the boys and 50% of the girls wear glasses. How many students wea

Nastasia [14]

First, you need to figure out hoe many boys and girls there are.

40% = 0.4

0.4 x 20 = 8 boys

20 - 8 = 12 girls

25% of the boys have glasses

0.25 x 8 = 2 boys who wear glasses

50% of the girls have glasses

0.5 x 12 = 6 girls who wear glasses

2 + 6 = 8

8 students wear glasses

Answer:

57.06 unit^2

Step-by-step explanation:

find the area of the rectangle = 12*12 = 144 unit^2

the area of the circle = pi*r^2 = 3.14*8^2 = 201.06 unit^2 (rounded to the nearest hundredth)

then the "shaded area" is the difference

201.06 - 144 = 57.06 unit^2
