Answer:
400 tiles :)
Step-by-step explanation:
2/5 = 160/x
1/5 = 80/x
80 *5 = 400
Answer:
I think it's 4 and why do I have to write 20 letters?
To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. Let's say we wanted to convert 82% to a decimal. We can think of 82% as the ratio 82 to 100 or 82 ÷ 100. When we divide by 100, it moves the decimal point 2 places to the left so 82 ÷ 100 would move the decimal point 2 places to the left which would give us .82. Therefore, 82% would = 0.82.
Yes. If we wanted to get even more specific, -2 is an integer, which falls under the label of the real numbers. √-2, on the other hand, is an imaginary number. The square root of -1 doesn't exist in the real numbers, so we invent a new number i with the property that i² = -1. Blending real and imaginary numbers together creates <em>complex numbers, </em>numbers with a real and imaginary part. This extension of the number system is tremendously useful because it essentially makes numbers two-dimensional, allowing us to manipulate and study them through a geometric lens.
70 degrees! This is the answer. Notice that the triangle ACF is isosceles, therefore, 35, 35 degrees, and 110 the vertex at F, then AB is 180 deg, so 70 left!
