Given:
Equilateral triangle: height = 2.6 inches ; base or side length = 3 inches
Rectangle: length = 6 inches ; width = 3 inches
1 name plate has 2 equilateral triangle and 3 rectangles.
Surface area of an equilateral triangle = √3/4 * a² = √3/4 * 3² = 3.9 in²
3.9 in² x 2 = 7.8 in²
Surface area of a rectangle = 6 in * 3 in = 18 in²
18 in² x 3 = 54 in²
7.8 in² + 54 in² = 61.8 in²
61.8 in² x 30 nameplates = 1,854 in² Choice A.
Answer:
B) 10 cm
Step-by-step explanation:
Hello!
We can use the Pythagorean theorem to solve for the hypotenuse.
Formula: 
- a = leg
- b = leg
- c = hypotenuse
We can plug in the values for each leg to solve for the hypotenuse.
<h3>Solve for c</h3>
The answer is Option B: 10 cm
Step-by-step explanation:
Step 1: On the horizontal axis, we can choose the scale to be 1 unit = 11 lb.Since the weights in the table start from 65, not from 0, we give a break/kink on the X-axis. Step 2: On the vertical axis, the frequencies are varying from 4 to 10.Thus, we choose the scale to be 1 unit = 2.
Hi!
The slope for the points given is
Answer:
area= 62.88
Step-by-step explanation:
to find the area of the whole figure take the diameter of the circle witch is 8 and multiply it by 11. the area of the whole figure including the semi-circle is 88.
now find the area of the whole circle and divide it in half.
A= pi * r^2 / 2
A= 3.14 * 4^2 /2
A= 3.14 * 16 / 2
A= 25.12
Now take the area of the semi-circle and subtract it from the whole figure.
88-25.12=62.88
