Answers:
680 to 578
340 to 289
250 to 212.50
Reasoning:
To find the percent of a number:
If the percentage is less than 100, we place a decimal point in front of the percent. Then, we multiply the percent by the whole.
For example, .15 x 680 = 102. Since 15% is less than 100, we place a decimal point in front of the 15. Then, we just multiplied it by the whole of 680.
We know that 102 = 15% of 680, so since that is the amount of money taken off the total, we subtract it: 680-102=578. Therefore, the new price is 578.
I did this for the rest of the questions, and there are 3 correct answers:
680 to 578
340 to 289
250 to 212.50
1 mile is 5280 feet, therefore, we have 60 miles, and each mile is 5280 feet, so we multiply 5280 and 60, you get the answer of 316,800 feet.
Answer:
A and D
Step-by-step explanation:
First we find the slope between the two given points.
m = (y2 - y1)/(x2 - x1) = (-5 - 2)/(7 - 6) = -7/1 = -7
Now we use the slope-intercept equation of a line.
y = mx + b
We use one point as x and y, and we solve for b.
2 = -7(6) + b
2 = -42 + b
b = 44
The equation is
y = -7x + 44
Answer: f(x) = -7x + 44
Answer:
x = 10, ∠ EHF = 110°
Step-by-step explanation:
7x and 11x are adjacent angles and sum to 180° , then
7x + 11x = 180
18x = 180 ( divide both sides by 18 )
x = 10
∠ EHF = 11x = 11(10) = 110°
