Answer:

This is 27% decrease.

Step-by-step explanation:

The amount of rainwater collected last year was 15.6 L, and this year it was 11.4 L, this means 15.6 L-11.4 L= 4.2 L less water was collected this year than last year.

This 4.2 L is

\frac{4.2L}{15.4L}*100

percent of the amount of water collected last year. Evaluating this we get:

\frac{4.2L}{15.4L}*100=0.269*100=26.9%

Rounding to the nearest percent this is 27%.

Thus, the percent decrease in the amount of rainwater collected is 27%.

Five friends attend a matinee movie and spend $8 per ticket. They also purchase a small bag of popcorn each. If the friends spen
ohaa [14]

Answer:

Formula: (cost of ticket + cost of popcorn) * # of friends = total cost

Which would give us (8 + x) * 5 = 62.5

Solve for x.

8 + x = 12.5 {divide each side by 5}

x = 12.5 - 8

x = 4.5

Each small bag of popcorn costs $4.50.

The radius of a circle is 4 feet. What is the area of a sector bounded by a 45° arc?
DIA [1.3K]

Answer:

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

Step-by-step explanation:

Given

Radius, r = 4ft

Angle, \theta = 45

Required

Calculate the area of the sector

When angle is given in degrees, the area of sector is calculated as thus;

Area = \frac{\theta}{360} * \pi * r^2

Substitute\ r = 4\ and\ \theta = 45

Area = \frac{\theta}{360} * \pi * r^2 becomes

Area = \frac{45}{360} * \pi * 4^2

Area = \frac{45}{360} * \pi * 16

Area = \frac{45*16}{360} * \pi

Area = \frac{720}{360} * \pi

Area = 2 * \pi

Area = 2  \pi\ ft^2

The above is the area in terms of π

Solving further.... (Take π as 3.14)

Area = 2  \pi\ ft^2 becomes

Area = 2 * 3.14\  ft^2

Area = 6.28\  ft^2

Hence, the area of the sector is

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

I’m confused on this one
tatyana61 [14]

6\sqrt2

Why?

We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

h^2=6^2+6^2\\\\h^2=36+36\\\\h^2=36\cdot2\to h=\sqrt{36\cdot2}\\\\h=\sqrt{36}\cdot\sqrt2\\\\h=6\sqrt2

In general, the formula for calculating the hypotenuse in an isosceles right triangle is h=a\sqrt2

a - a leg, h - a hypotenuse
