Suppose 2.7 gallons of water come out of a faucet each minute. Find the amount of water coming out in 1.2 minutes.
Answer:
3.24 gallons
Step-by-step explanation:
2.7x1.2=3.24
Answer:
3.24
Step-by-step explanation:
1.2 is 1 whole plus 20/100
so 1*2.7=2.7
.2*2.7=0.54
0.54+2.7= 3.24

Answer:
y = 7
Step-by-step explanation:
Mathematically, according to the Pythagoras’ theorem;
The square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the two other sides
The hypotenuse is the side that faces the right angle and it is represented by the square root of 85 here
Thus, we have it that;
(√85 )^2= 6^2 + y^2
85 = 36 + y^2
y^2 = 85-36
y^2 = 49
y = √49
y = 7

Margaret and Kevin both have to write an expression that is equivalent to 6 to the power of -4. Part A Who is correct? Part B What is a possible error made by the incorrect student?
Margaret writes 6 x (1/6 to the power of 5)
Kevin writes 1/6 x (6 to the power of 4)
Please help
Answer:
Margret is correct, Kevin is wrong.
Step-by-step explanation:
6^-4 can be written as (1/6)^4
By taking (1/6)^5 times you have (1/6)(1/6)(1/6)(1/6)(1/6), multiplying by 6 would cancel one of those (1/6ths) out. Meaning you would be left with (1/6)^4 or 6^-4
Kevin is wrong because taking 6^4 would not be the same as 6^-4, 6^4= 1296, multiplying that by 1/6 would not give you the same value as 6^-4. His mistake was that he did not take the reciprocal of 6^-4 and incorrectly removed a negative.

Gavin rolls a fair dice 30 times.
How many times would Gavin expect to roll a five?
The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.
What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total outcomes = {1, 2, 3, 4, 5, 6]
Total number of outcomes = 6
Favourable outcomes = {5}
Total number of favourable outcomes = 1
Probability of rolling 5 = 1/6
The expected number of 5's would be 30×(1/6) = 5 times
Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

Answer:
x = 4, y = 5
Step-by-step explanation:
[tex]2x-y=3\\4x-2y=6[/tex]
so:
[tex]4x - 2y = 6\\+ 5x + 2y = 30\\9x= 36\\x=4[/tex]
Substitute this into 2x - y = 3:
[tex]8-y=3\\y = 5[/tex]

Y varies directly as X and inversely as the square of Z. Y=30 when X=75 and Z=5. Find Y when X=36 and Z=2
Answer:
Y when X=36 and Z=2 is 90
Step-by-step explanation:
Given -
Y varies directly as X and inversely as the square of Z
[tex]y = \frac{kx}{z^2}\\30 = \frac{k *75}{5^2} \\30 = 75k/25[/tex]
[tex]k = 10[/tex]
As we know
[tex]y = \frac{kx}{z^2}[/tex]
Substituting value of X = 36 and Z = 2 in above equation, we get -
[tex]y = \frac{10*36}{2*2} \\y = 90[/tex]

If there are 180 students in the girls athletics program, then
how many students participated in soccer?
Answer:
27
Step-by-step explanation:
15: 100 = x : 180
x = (180 x 15) / 100 = 27
Answer:
27
Step-by-step explanation:
Seems like your question(shown/written) is incomplete. Based on the given data.
15% of the total students participated in soccer
15% of 180 students participated in soccer
=> 15/100 x 180
=> 2700/100
=> 27
27 students participated in soccer
