The balance in my bank account went down $85 in 15 days. How much did it change per day. Use a positive number to represent a gain of money and a negative number to represent a loss of money.
The change in balance is a loss of money, so the change is -85.
The change of -85 occurred in 15 days, so the average change per day is
-85/15
Answer:
D = 100 - 2p
Where p is the price in dollars of the product and D is the number of products that can be sold at that price
And we need to interpret the slope of this function mean in the context of the problem. And for this case the slope is m=-2 and it means that for every increase in the price in 1 $ we will have a decrease the number of products in two units
Step-by-step explanation:
For this problem we know the following function given:
D = 100 - 2p
Where p is the price in dollars of the product and D is the number of products that can be sold at that price
And we need to interpret the slope of this function mean in the context of the problem. And for this case the slope is m=-2 and it means that for every increase in the price in 1 $ we will have a decrease the number of products in two units
Answer:
The two people should stand 40 feet from the center so that they can hear each other whisper
Step-by-step explanation:
From the question
Width of the gallery = 100 feet
Width = 2a
a = Width/2
a = 100/2 = 50 feet
Height of the gallery = b = 30 feet
Hence, the distance is
d² = a² - b²
d = √a² - b²
d = √50² - 30²
d = √2500 - 900
d = √1600
d = 40 feet
Hence, the two people should stand 40 feet from the center so that they can hear each other whisper.
I would go with 45,45, 90 because first you can eliminate C and D.
C because it is not an equilateral triangle and D because you can figure it out.
Now you have A and B. A 30, 60 90 Degree Triangle would mean that none of the sides are equal (or the legs don't equal the hypotenuse when you put it in Pythagorean form [a²+b²=c²]). However if you translate the problem to answers that are easier to understand: {(7√3 = 12.124)² + 21² = 587.8944 = 14√3} Then you can see, two angles are equal to each other. So the answer is B.
