The cost is the cost per pound times the number of pounds minus the coupon.

If $p$ pounds are purchased, she will pay $3.50p-3.25$ .

If 3 pounds are purchased, she will pay 3.50(3)-3.25=7.25.

Write the product using exponents -3/7×3/7×3/7

zlopas [31]

Answer:

$-(\frac{3}{7})^3$

Step-by-step explanation:

Since we see that 3/7 is multiplied by itself three times, we can use exponents as a shorter way to write this. The expontent tells us how many times the base number, 3/7, is multiplied by itself.

$-1 * (\frac{3}{7})^3$ = $-1 * \frac{3}{7} * \frac{3}{7} * \frac{3}{7}$

We then multiply by -1 to (3/7)^3 to get the exact answer.

$-(\frac{3}{7})^3$

Need help with trigonometry

vovangra [49]

Answer:

$\sf \tan(A) & =\dfrac{9\sqrt{22}}{44}$

Step-by-step explanation:

If angle C is the right angle, then side c is the hypotenuse.

Use Pythagoras' Theorem $a^2+b^2=c^2$ to find the length of side a:

Given:

b = 2√22
c = 13

$\implies a^2+(2 \sqrt{22})^2=13^2$

$\implies a^2+88=169$

$\implies a^2=81$

$\implies a=\sqrt{81}$

$\implies a=9$

Tan Trig Ratio

$\sf \tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle

Given:

$\theta$ = A
O = side opposite angle A = a = 9
A = side adjacent angle A = b = 2√22

$\begin{aligned}\implies \sf \tan(A) & =\dfrac{9}{2\sqrt{22}}\\\\ & =\dfrac{9}{2\sqrt{22}} \times \dfrac{\sqrt{22}}{\sqrt{22}}\\\\ & = \dfrac{9\sqrt{22}}{44} \end{aligned}$

A square dance floor has a perimeter of 120 yards. What is the length of a diagonal of the dance floor?

Crazy boy [7]

Answer:

Hey!

Your answer is C.42.4yd

Step-by-step explanation:

There are 2 ways you can work this on out...

1. Using Pythagoras Theorem...

= 30^2 + 30^2 = 1,800 (30^2=900 so you've added 2 of those to make 1,800)

= SQUARE ROOT THE ANSWER OF 1,800

$\sqrt{x} 1,800$ = 42.42640687119285‬

TO GET A MORE PRECISE ANSWER WE ROUND IT UP TO 1 decimal place

= 42.4 yd is the diagonal length of the dance floor!!

HOPE THIS HELPS!!
