Answer:
Step-by-step explanation:
Let the number of ounces of
A = x
B = y
A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?
Our system of equations is given as
x + y = 90.... Equation 1
x = 90 - y
40% × x + 55% × y = 45% × 90 ounces
0.4x + 0.55y = 40.5....Equation 2
We substitute 90 - y for x in Equation 2
Neither are true there are 2.9 grams or sugar in a carrot per serving and 14 grams of sugar per serving in a banana.
First you do -5t squared, you do -5*-5 to get positive 25t and add it to 25t to get 50t and 2. In order to get the answer you have to divide 50 by 2 since 2 needs to also get rid of, so 50/2=25t! So t=25
Step-by-step explanation:
a) if the population is 3000 and it is being multiplied 1.15 than it is 15%. I found this by multiplying 1.15 by 100 to make it percent than anything over 100 is an increase.
b)im not so sure on this one but I think if t = 0 than it would be p= 3000 x 1.15 x0 which would equal 0
c) p = 3000x 1.15 x 24 p = 82,800
Hi there!
The answer is:
Let the input be represented by X. We can see we have to multiply it by -3/4, so we get -3/4X. To find our outcome (which is represented by y), we only have to add 2 to the function.
y (outcome) = - 3/4x (income) + 2
