Answer:
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
Step-by-step explanation:
convert feet to yard:
1 yard=3 feet so
12 feet=4 yards
10 feet=10/3 yard=3.33333 yard
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
The length of hypotenuse is 39.
Step-by-step explanation:
Given,
Vertical side = a = 15
Horizontal side = b = 36
Hypotenuse = c
Using pythagorean theorem
Taking square root on both sides
The length of hypotenuse is 39.

Answer:
- C for question 1
- A for question 2
Step-by-step explanation:
First Question
What you need to do here is pick an answer that will result in a decrease. If you have something like 1.3 * e ^ (0.038 * t), what will happen when t = 20
P = 1.3 * e^(0.038*20) = 1.3*e^0.76 = 2.77 which is getting bigger not smaller.
So what you want is something like 1.3 * e^-0.76 = 0.67
So which question is configured that way?
It's either C or D. but which one? It cannot be D. 0.38 is far too big: it does not represent 3.8%
C does represent 3.8% as a decimal. It is the correct answer.
Answer: C
Second Question
Every time she sells a ticket, the total that she gets is 4 more than what she had before.
The variation is a direct one. It is y = k*x. But what is k? Is it 4 or is it 1/4?
Read the first sentence above. She gets 4 dollars more, not 1/4 of a dollar.
C and D are both wrong because those equations think she is getting 1/4 more.
B is wrong because it says that the relationship is inverse. It is not. It is direct.
The answer is A
Answer:
5
Step-by-step explanation:
•
×
since 5 is squared the square root cancels out
so 5
Answer:
Well, this is a simple equation when you look at it. Obviously, the answer is Zero. No matter how you rearrange the equation, the answer shoud always be Zero
initial equation: 2+2–4?
Altered equations:
-4+2+2?
2–4+2?
it is always the same. If i were to draw a number line, every time you add two; move two to the right, everytime i subtract four; move 4 to the left. Try it, the answer will always be Zero.
There are also acronyms: BODMAS, BIDMAS, PEDMAS Et Cetera.
these are the order(s) of operations. Search it up. If one ever comes across an equation where all operations are equivalent then solve it from left to right.
Step-by-step explanation:
The answer is 0. Why? Because of the commutative property that basically says no matter what order the numbers are in you'll always yield the same answer. (3+2=5 and 2+3=5)
In this case, 2+2-4=0 because (2+2)=4 , and 4-4=0 because 4 and -4 are additive inverses.
2+2-4=0
4-4=0
0=0
Or
2+2-4=0
2+(-2)=0
2-2=0
0=0
