Mark costs a shadow that is 4-feet long. At the same time, a nearby tree costs a shadow that is 20-feet long. If mark is 6 feet tall, how tall is the tree?
Answer:
30 feet
Step-by-step explanation:
For this problem we can use ratios 6:4 and x:20. We can also write these ratios as fractions 6/4 and x/20 or 3/2 and x/20. Set the two fractions equal to each other and solve for x:
3/2 = x/20
1.5 = x/20
30 = x
Is this correct? Look at pic attached
Answer:
Perfect!
Step-by-step explanation:
Complementary= 90 degrees
Supplementary= 180 degrees
Looks like you got both of those. Good job!
<1 + <2 = 90
<1 = 55
90-55=35
<2=35
<2+ <3= 180
180-35= 145
<3 = 145 degrees
You did awesome! Amazing job!

Write an explicit function to represent the following sequence.
3,9, 27, 81,...
Answer:
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.

One ninth of the students in Mr. Beck’s class list red as their favorite color. Twice as many students call blue their favorite, and three times as many students prefer pink. The rest name green as their favorite color. If 6 students call blue their favorite color, how many students are in Mr. Beck’s class?
Answer:
27
Step-by-step explanation:
this is because 6 students is 2/9th of the class and if we divide that by two we get 3. 3 is 1/9th od the class so we multiply it by 9 to get 27 which is how many students should be in his class if i am right

coral invested $500 in an account that earns simple interest at the rate of %5.5 each year. Assuming coral does not invest anymore money it will take how many years for coral to have %720 in her account?
Answer:
The number of years it will take coral to have $720 in her account is 8 years
Step-by-step explanation:
The principal amount coral invested, P = $500
The simple interest rate earned per year, r = 5.5%
The amount in coral account after t years, A = $720
The formula for simple interest is given as follows;
[tex]Simple \ Interest, \ SI = \dfrac{Principal, P \times Rate, r \times Time, t}{100}[/tex]
The formula for amount, A = SI + P
Therefore, we have;
[tex]A = \dfrac{P \times r \times t}{100} + P[/tex]
[tex]720 = \dfrac{500 \times 5.5 \times t}{100} + 500[/tex]
[tex]720 - 500 = \dfrac{500 \times 5.5 \times t}{100}[/tex]
[tex]220 = \dfrac{500 \times 5.5 \times t}{100}[/tex]
22000 = 500 × 5.5 × t
t = 22000/(500 × 5.5) = 8
The number of years, t, it will take coral to have $720 in her account = 8 years.

If f (x)
-3x + 2 and g (2) = x + 1 find g(f(x)) please helppp
[tex]\left \{ {{f(x)=-3x+2} \atop {g(x)=x+1}} \right.[/tex]
To find g(f(x)), Substitute f(x) in g(x).
[tex]g(-3x+2)[/tex]
Then substitute x = -3x+2 in g(x) = x+1
[tex]g(-3x+2)=(-3x+2)+1\\g(-3x+2)=-3x+2+1\\g(-3x+2)=-3x+3[/tex]
Therefore, the answer is [tex]g(f(x))=-3x+3[/tex]
