Step-by-step explanation:

Given

Reader' Book Club

Membership = \$12

Book = \$4.00 per book

Perfect Page

Book = \$7.50 per book

Required

Write an inequality to represent the situation

<em>Represent the number of books with b</em>

Hi can anyone pls help me in dis math problem!!!!! I will mark u as brainliest
FinnZ [79.3K]

Answer:

See explanation

Step-by-step explanation:

Statement 3 is a lie because the mascot for the Philadelphia Phillies is Phillie Phanatic, not Gritty. Statements 1 and 2 are true because the slope of a line expresses how quickly the y value changes over the course of x, and the y intercept of y=3x-5 is negative because -5 is negative. Hope this helps!

The figure shows a quarter circle and an equilateral triangle. What is thearea of the shaded part? Give your answer to 3 signifi
ad-work [718]

Explanation

The shaded area represents a segment. This can be solved with the formula below;

\mleft(\frac{\theta}{360}\mright)\times\pi r^2-\frac{1}{2}r^2sin\theta

Since the triangle is an equilateral triangle, it implies that the angle subtended at the centre is 60 degrees. Also, the given radius is 7 cm

\begin{gathered} =7^2(\frac{60}{360}\times3.14-\frac{1}{2}\times\sin 60)^{}_{} \\ =49(\frac{3.14}{6}-\frac{\sqrt[]{3}}{4}) \\ =4.43\operatorname{cm}^2 \end{gathered}

Answer:

4..43\operatorname{cm}^2
