During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 84 centimeters in 6 days, what is the water level increase rate in centimeters per day?
Answer:
14 cm per day
Step-by-step explanation:
To find the water level increase rate in cm per day, divide 84 by 6, since it increased by 84 cm in 6 days:
84/6
= 14
So, the water level increase rate in 14 cm per day

Tickets to the varsity basketball game cost $4 for students, but adults pay $6, and discount tickets are $5 for senior citizens and active military. At a recent game, 353 tickets were sold for a total of $1,660. If there were twice as many student tickets sold as adult tickets, what system of equations could be used to find how many of each type of ticket were sold?
Answer:
4s + 6a + 5c = 1,660
s = 2a
s + a + c = 353
Step-by-step explanation:
s = # of student tickets bought
a = # of adult tickets bought
c = # of senior citizen tickets bought

When f(c)= 10x^2 + 3x -4, evaluate f(-4)
Answer:
[tex]f(x) = 144[/tex]
Step-by-step explanation:
This problem deals with a function. All this question is asking is to plug in -4 every time an x appears.
So, let's do that:
[tex]f(-4) = 10(-4)^{2} + 3(-4) - 4[/tex]
[tex]f(-4) = 10(16) - 12 - 4[/tex]
[tex]f(-4) = 160 - 16[/tex]
[tex]f(-4) = 144[/tex]
A ball is dropped and bounces to a height of 5 feet. The ball rebounds to 70% of its previous height after each bounce The function that could be used to model the nth term in the sequence of heights of the ball after the initial drop is
Answer:
[tex]T_n = 7.143(0.7^n)[/tex]
Step-by-step explanation:
If a ball bounces to a height of 5feet, the initial drop = 5feet
If the ball rebounds to 70% of its previous height after each bounce, the next height after rebouncing will be expressed as;
= 70% of 5
= 70/100 * 5
= 0.7*5
= 3.5 feet
The next height will be 0.7*3.75 = 2.45 and so on
The heights wil form a sequence as thus;
5, 3.5, 2.45...
This sequence forms a geometric progression.
To get the function that could be used to model the nth term in the sequence of heights of the ball after the initial drop, w will find the nth term of the sequence
[tex]T_n = ar^{n-1}[/tex]
a is the first term of the sequence
n is the number of terms
r is the common ratio
From the sequence:
a = 5
[tex]r = \frac{3.5}{5} = \frac{2.75}{3.5} = 0.7[/tex]
Substitute the given values into the formula
[tex]T_n = 5(0.7)^{n-1}\\T_n = 5(\frac{0.7^n}{0.7^1} )\\T_n = \frac{5}{0.7}\times 0.7^n \\T_n = 7.143(0.7^n)[/tex]
The nth tern=m required is [tex]T_n = 7.143(0.7^n)[/tex]

following expression of -9(3x-7)
Answer:
-27x+63
Step-by-step explanation:
you do -9 times 3x then -9 times -7, two negatives creates a positive, and so 9 times 7 equals 63
hope this helps :^)
-9(3x-7)
Multiply each term in the parentheses by -9
-9×3x-9×(-7)
Calculate the product
-27x-9×(-7)
now we do the same thing only different way ok
-9×3x
Multiplying a negative and a positive equals a negative : (-)x(+)=(-)
-(9×3)x
Multiply the numbers
-27x
-9×3x-9×(-7)
Multiply the numbers
-27x+63
Now we do the same thing only different way ok
-9×(-7)
Multiply two negatives equals a positive: (-)×(-)=(+)
9 × 7
multiply the numbers
63
Solution: -23x+63

How much work is done if a person carries 5n of candy 25m when trick or treating
The amount of work done if a person carries 5n of candy 25m when trick or treating is 125.
In order to determine the amount of work done we are going to multiply the force by the distance.
Using this formula
Work done = Force x Distance
Where:
Force = 5n
Distance = 25m
Let plug in the formula
Work done = 5 x 25
Work done= 125
Inconclusion the amount of work done if a person carries 5n of candy 25m when trick or treating is 125.

We are given;
Force carried; F = 5n
Distance covered; d = 25 m
Now, the formula for work done is given as;
Work done = Force × Distance
Thus;
Work done = 5 × 25
Work done = 125 N.m

James has $40 to spend. He wants to buy 2 tickets to a show. He has to spend $7 to get where tickets are sold. The following inequality can be used to find out the highest price James can afford to pay for each ticket. 2x+7 less than or equal to 40.
A.) x less than or equal to 23.5
B.) x less than or equal to 16.5
C.) x greater than or equal to 23.5
D.) x greater than or equal to 16.5
Answer:
B.) X less than or equal to 16.5
Step-by-step explanation:
If you take his limit, 40 and subtract the 7 dollars you will get 33. Then, divide that by two because he will need two tickets and you will get 16.5. It can't be greater than 16.5 because he will go over his budget.
Answer:
x ≤ 16.5
Step-by-step explanation:
40 ≤ 2t + 7 Subtract 7 from both sides.
40 - 7 ≤ 2t + 7 - 7
33 ≤ 2t Divide both sides by 2.
[tex]\frac{33}{2}[/tex] ≤ [tex]\frac{2t}{2}[/tex]
16.5 ≤ t or t ≥ 16.5

Answer: 15, and 44 are integers.
Step-by-step explanation: For 15 to be an integer, 15 has to be a whole number. Furthermore, for 15 to be an integer, you should be able to write 15 without a fractional or decimal component. 15 is a whole number that can be written without a fractional component, thus 15 is an integer, as well as 44.

Can anybody please help me
Answer: B
Step-by-step explanation:
We have to find the amount that Maya painted IN ALL, which means we must add 3/4 and 1/8. First, look for the answer choice that has 1/8 as a number (B and A). However, none of the answer choices have 3/4 as an answer, so we must convert it into an equivalent fraction, 6/8. You get 6/8 by multiplying both the numerator and denominator by 2. Therefore the answer is B.

Tim dug a hole that was 16 1/2 inches deep. He left a pile of dirt next to the at was inches high. Show how you could use subtraction to find the e from the top of the pile of dirt to the bottom of the hole. 8 3/4 Tim dug a hole that hole that was distance from the
Answer: 2 inches
Step-by-step explanation:
14 inches
Step-by-step explanation:
Length of the hole = 16(½) inches
Length of the dirt = 8(¾)inches
The distance between the top of the pile to the bottom of the hole = ?
Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.
Distance from the top to the bottom = length of dirt + length of the hole
Length of dirt = 8×¾ = 6 inches
Length of the hole = 16 × ½ = 8 inches
Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches
Distance from the top of the dirt to the bottom of the hole = 14 inches
Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left
Distance left = length of hole - length of dirt
Distance left = 8 - 6 = 2 inches .
