Math help please 14 points and brainiest!!!

Cloud [144]

The reason is because she didn't survey the school, but only surveyed her class, and to add to that It didn't say it was a random selection of students. Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories. Just because most of her class chose short stories she believes the rest of the school will have the same choice.

I need help!! Find the area of each shaded segment. Round your answer to the nearest 10th

guajiro [1.7K]

Given:

θ = 60°

Radius = 8 in

To find:

The area of the shaded segment.

Solution:

Vertically opposite angles are congruent.

Angle for the shaded segment = 60°

Area of the sector:

$$A=\pi r^2\times \frac{\theta}{360^\circ}$

$$A=3.14 \times 8^2\times \frac{60^\circ}{360^\circ}$

A = 33.5 in²

Area of the sector = 33.5 in²

Area of triangle:

$$A=\frac{1}{2} bh$

$$A=\frac{1}{2} \times 8\times 8$

A = 32 in²

Area of the triangle = 32 in²

Area of segment = Area of sector - Area of triangle

= 33.5 in² - 32 in²

= 1.5 in²

The area of the shaded segment is 1.5 square inches.

Suppose a system of two linear equations has one solution. What must be true about the graphs of the two equations?

DaniilM [7]

When two linear equations have only one solution the two lines on a graph would intersect each other ( they would only touch in one spot).

line segment with one endpoint at (2,5) is divided in the ratio 4:5 by the point (10,1). which coordinates could represent the o

rodikova [14]

Answer:

(20,-4)

Step-by-step explanation:

We are given;

One end point as (2,5)

Point of division as (10,1)

The ratio of division as 4:5

We are required to calculate the other endpoint.

Assuming the other endpoint is (x,y)

Using the ratio theorem

If the unknown endpoint is the last point on the line segment;

Then;

$\left[\begin{array}{ccc}10\\1\end{array}\right]$ = $\frac{4}{5} \left[\begin{array}{ccc}x\\y\end{array}\right]$ + $\frac{5}{9}\left[\begin{array}{ccc}2\\5\end{array}\right]$
