Answer:
34.4
Step-by-step explanation:
10% is the same thing as 0.1 so 344 times 0.1 is 34.4
A percent (%) is equal to 1/100 (We actually don't call that 'per''cent' for no reason)
So 10% is actually 10 times % which is:
If you get a calculator and calculate 1/10 the calculator should give 0.1
You might be taught that to get the decimal form from percent you just move the decimal point to the left twice (like 34% -----> .34) but if you do this, you are essentially dividing by 100 or multiplying by 1/100
now you know 10% is 0.1 the next thing to do is multiply it to 344.
Answer:
C (-2, 0)
Step-by-step explanation:
y = x+2
intersect the x-axis when y = 0, then
0 = x+2
x = -2
Answer: 6 cups
Step-by-step explanation:
You need to find a unit rate...
48/2= 1 cup for 24 cookies (unit rate)
144/24=6 so you need to multiply 1 and 24 each by 6
1*6=6
24*6
to get...
6 cups for 144 cookies
Answer: No
Step-by-step explanation:
The question is whether 3(4x+2) could ever equal 6(2x+2). So let's set them equal to each other and find if there is a value of x, the days, where they are equal.
3(4x+2) = 6(2x+2)
12x + 6 = 12x+2
6 = 12?? No
They will bnever be at the same height. They are growing at the same rate (12x) but starting at different heights (6 and 12)
