Casey bought sandwiches and bags of chips. Each sandwich cost three times asmuch as a bag of chips. She bought 5 sandwiches for

Greetings!

Let's rewrite the equation:
b = 4c - s².
Plug in your values:
b = 4(25) - (9)²
Now simplify:
4 times 25 equals 100
9 squared equals 81
So, b = 100 - 81
Calculate:
100 minus 81 equals 19
b is 19.

I hope this helps!

The triangle is positioned within the circle, with its vertices lying on the circle's edge - since the center of the circle is located on the hypotenuse, that hypotenuse serves as the diameter (D) of the circle.

:

D = 120 feet

:

Calculating the circumference of the circle gives: 22/7 * 120 = 377.14 feet.

The perimeter of the triangle is calculated as 120 + 60 + 103.92 = 283.92

1) The combined distance around both circle and triangle totals 661.06 feet.

2) The vertices for the triangle's central area must touch the circular pool - to find the center of the pool, draw perpendicular bisectors from two of the triangle's sides; where they meet is the center.

The distance from the center to any vertex of the triangular area represents the radius of the

circular pool.

4) The pool's volume is calculated as ((π * 60^2) - area of triangle) * 4 =

(11314.285) - (1/2 * 103.92 * 60) * 4 = 32786.74 cubic feet.

Response:

e. 545

Detailed explanation:

In a survey sample containing n individuals, with a success probability of , and a confidence level of , the ensuing confidence interval for proportions is established.

Wherein

z denotes the z-score corresponding to a probability value of .

For this scenario, we find:

The estimate averages the two bounds. Thus

95% confidence level

Consequently, z represents the z value corresponding to the p-value of , hence .

The lower boundary of this interval is:

In this query, L = 0.82. Therefore

Thus, the accurate response is:

e. 545

Because SI units are structured around powers of 10, you can shift the decimal point to convert; imperial units lack that base-10 organization, so the decimal-shifting method doesn't apply.

We understand that

1 foot corresponds to 12 inches.

Step 1

Dimensions of the plywood needed are

(12+3+3) x (18+3+3)------> 18 inches x 24 inches.

Step 2

Convert inches into feet:

18 in-------> 18/12=1.5 ft.

24 in------> 24/12=2 ft.

Step 3

To calculate the area of plywood needed:

A=b*h------> 1.5*2------> A=3 ft².

The final result is

3 ft²
