To find the answer all you do is switch the percentage to a decimal and multiply by the number you were given. For example on 1a, 19% as a decimal is 0.19 and 0.19 * 360 is 68.4. All of 1 and 2 questions work this way. For number three, take the fraction and convert it to a decimal (so 1/2 will be 0.5, 1/3 will be 0.33, etc) and add that to the whole number. For example, 3a would be 33.33%. 3b would be 12.5%.
Hope this helps!
Answer:
22
Step-by-step explanation:
convert into mixed fraction
11/2 divided by 1/4
then keep change flip
11/2 *4/1
then cancel common factor and cross multiply
11*2/1*1=22
T(t) = temp at any given time t = time. To = initial temp of the heated object ... A cake removed from the oven has a temperature of 210°F It is left to room that has a temperature of 70°F. After 30 minutes, the temperature of in is 140°F a. Use Newton's Law of Cooling to find a model for the temperatur ... 20 = 1402 -0.02317.
If the product of the present age of father and his daughter is 430 and the age of father was 4 times as old as his daughter is now, then the present age of father is 43 and the present age of daughter is 10.
Given that the product of the present age of father and his daughter is 430 and the age of father was 4 times as old as his daughter is now.
We are required to find the present age of the father and daughter.
Suppose the present age of the father is x.
Suppose the present age of his daughter is y.
We are given product of present ages be 430.
xy=430----------1
y=430/x
According to question,
x-3=4y
Put the value of y=430/x.
x-3=4*430/x
-3x=1720
x=(3±
)/2*1
x=3±
)/2
x=(3±83)/2
x=(3+83)/2
(Ignoring the negative value because the age cannot be negative as it is coming before the greater number)
x=43
y=430/x
y=430/43
y=10
Hence if the product of the present age of father and his daughter is 430 and the age of father was 4 times as old as his daughter is now, then the present age of father is 43 and the present age of daughter is 10.

Answer:
G(x)=(x-4)+9
Step-by-step explanation:
If the graph going to the left or right, then it will in like (x plus or minus #). REMEMBER THE SIGN WILL BE OPPOSIT FOR EXAMPLE: IF IT SAY RIGHT, THEN OPPOSIT SIGN WILL BE NEGATIVE (minus). IF IT SAY LEFT, THEN OPPOSIT SIGN WILL BE POSITIVE (plus).
If the graph looking up or down, then it will be like: (x) plus or minus #. THE SIGN ARE THE SAME. FOR EXAMPLE: IF IT SAY UP, THEN IT IS PLUS (positive). IF IT SAY DOWN, THEN IT IS MINUS (negative)
