Here are two patterns made using identical rhombuses. Without using a protractor, determine the value of a and b.
Answers
Answer:
a = 60°
b = 120°
Step-by-step explanation:
First, you can find measure a by using the first shape. There are six rhombuses, and you can use the innermost a of each one to form a circle. A full circle is 360°, so divide 360 by six. The answer is sixty. So on the next shape, the a measurements add up to 120°. Subtract that from the circle: 360 - 120 = 240. And since there are two measurements for b, you would divide 240 by two. The answer is 120.
To check your work, use the knowledge that circles are 360° (the four interior corners of a rhombus will also add up to 360°. 2(120) + 2(60) = 360. Hope this helps! Feel free to ask any questions!

A wall is 12 feet long and 8 feet tall. There is a square window 4 feet long in the wall. What is the area of the wall surface?
1. 96 ft 2
2. 80 ft 2
3. 92 ft 2
4. 32 ft 2
Answers
Answer:
80 ft2
First let's find the total area of the wall: 12 x 8 = 96. Then, we need to subtract out the window. To find the area of the wall, we'll need to find the area of the window and subtract it from the total area of the wall: 4 x 8 = 32 | 96 - 32 = 64. However, I am assuming the height of the window is 8 feet. If the window is 1 foot tall, the answer is 92 feet. If the window is 4 feet tall, the answer is 80 feet.
(The first and last answers are incorrect) As there is no picture provided, as I am assuming there is a picture, please follow my instructions left for you above as to what the answer would be depending on the height of the window.

What is the product of 1.65 and 1.05 x 10^-2
Enter your answer in the box using standard notation. Use an initial 0 and a decimal point as needed
Answers
The product of the exponents is 1.7325 x 10⁻².
Given data:
To find the product of 1.65 and 1.05 × 10⁻², multiply the two numbers:
A = 1.65 × 1.05 × 10⁻²
From the laws of exponents:
mᵃ×mᵇ = mᵃ⁺ᵇ
First, multiply the decimal numbers:
1.65 × 1.05 = 1.7325
Next, multiply the result by 10⁻², which is equivalent to moving the decimal point two places to the left:
1.7325 × 10⁻² = 0.017325
Hence, the product of 1.65 and 1.05 × 10⁻² is 0.017325.
