Bought 16 packs of cola each pack had 6 cans he drank 9 cans how many are left?
Answer:
87 cans left
Step-by-step explanation:
multiply.16 x 6 =96 then you subtract 9 and you get 87 cans
There are 87 cans of cola left.
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If there are 6 cans in a pack, and you bought 16 packs.
Total cans.
= 6 x 16
= 96 cans
If you drank 9 cans, then the number of cans left.
= 96 - 9
= 87 cans.
Therefore,
There are 87 cans of cola left.

Find the mean, u, for the binomial distribution which has the stated values of n and p. Round answer to the nearest tenth. n=676; p=0.7
Answer:
[tex]\mu=473.2[/tex]
Step-by-step explanation:
Binomial Distribution
The binomial distribution is commonly used to model the number of successes in a sample of size n drawn with replacement from a population of size N.
The mean value of a binomial distribution is given by:
[tex]\mu=np[/tex]
Where b is the number of trials and p is the success probability for each trial.
We need to find the mean value with parameters n=676 and p=0.7, thus:
[tex]\mu=676\cdot 0.7[/tex]
[tex]\boxed{\mu=473.2}[/tex]
Write an equation in slope-intercept form for the line that passes through (−2, 3) and is parallel to
the line with the equation 3x + 2y = 6.
y= (-3x+6)2
For parallel lines, slopes are the same,
y = mx + c
Substitute the values,
3 = (-3/2)(-2) + c
3=3 + c,
c = 0
Thus, the equation is y= -3/2x

Step-by-step explanation:
From 2010 to 2011, the population of Queens increased by 16,075. Brooklyn’s population increased by
11,870 more than the population increase of Queens.
a. Estimate the total combined population increase of Queens and Brooklyn from 2010 to 2011.
(Round the addends to estimate.)
b. Find the actual total combined population increase of Queens and Brooklyn from 2010 to 2011.
c. Assess the reasonableness of your answer in (b). Use your estimate from (a) to explain.
Answer:
The population of Queens increased by 16,075.
The population of Brooklyn increased by 11,870 more than that, then the population of Brooklyn increased by:
16,075 + 11,870 = 27,945
a) The total combined population increase is (when we round the addens)
I will round in the thousands place.
To do it, we must look at the hundreds place, if the decimal is 5 or larger, we round up.
If the decimal is smaller than 5, we round down.
16,074 ≈ 16,000
27,945 ≈ 28,000
16,000 + 28,000 = 44,000
b) Now using the actual numbers:
16,075 + 27,945 = 44,020.
c) now let's compare our two results:
Let's see the difference between them
a = 44,000
b = 44,020
a - b = 44,000 - 44,020 = -20.
This means that our estimated from (a) is 20 units smaller than the actual number.
But this is insignificant compared with the 44,020.
Why?
we can calculate the relative error as:
100%*(estimate value - real value)/(real value)
100%*(-20/44,020) = -0.05%
So the error is on the -0.05%, which is despreciable.
From this, we can conclude that the estimation in (a) is a really good estimation.

Answer:
D
Step-by-step explanation:
y = a[tex]x^{2}[/tex] + bx + c is an equation for a parabola in standard form.
y = a(x - h)² + k is the equation for a parabola in vertex form.
We use y = because the parabola opens vertically.
The vertex is the point on the curve of the parabola, so either the lowest or highest point depending on whether it opens up or down.
We are given the vertex of (1,3), is the vertex formula h is the x and k is the y.
(h,k) or in this case (1,3).
Let's substitute the vertex.
y = a(x - 1)² + 3
To find a, we use the other point (2,6) to substitute in x and y to solve.
x = 2 y = 6
6 = a(2 - 1)² + 3
6 = a(1)² + 3
6 = a(1) + 3
6 = a + 3 Subtract 3 from each side.
6 - 3 = a + 3 - 3
6 - 3 = a
3 = a
Now we have all the elements of the equation.
a = 3
h = 1
k = 3
y = 3(x - 1)² + 3
So the answer is D.

find two consecutive ODD numbers whose sum is 144.
Answer:
Smaller=x Larger=x+2
x+x+2=144
2x+2=144
2x+2-2=144-2
2x=142
2x/2=142/2
x=71
Smaller=71
Larger=73
Check: 71+73=144
Step-by-step explanation:
please mark me as the brainliest answer and please follow me for more answers to your questions.
Answer:
71 and 73
Step-by-step explanation:
First, set up an equation: let x be the smaller number, and let x+2 be the bigger one.
Then, since these two number's sum is 144, we can set up the equation x+(x+2) = 144.
Solve for x: 2x+2=144 -> 2x = 142 -> x = 71
As the smaller number is defined as x, we solved for the smaller number: 71. The bigger number is defined as x+2, so the bigger number is just going to be 2 more than the smaller number, which is 73.
Therefore, we arrive at our answers 71 and 73.

a certain journey took 40 min to complete. if half of the distance was travelled at an average speed of 100 km/h and the other half at an average speed of 60 km/h, what was the total length of the journey
total time taken = 40 min
let x be the total length/ distance of the journey.
speed(v) = distance/ time
100= (1/2 x)/ time ---1
60= (1/2 x)/ time ---2
add 1 and 2
160= x/40
where 40 is the total time taken
44.44m/s= x/ 2400s (i converted the speed and time)
x = 106,656 metres = 106.656km
the total length is 106.656 km.
Let's assume the total length of the journey is "x" km. Since the journey took 40 minutes to complete, we first need to convert this time to hours, which is [tex]40/60 = 2/3 h[/tex] hours.
According to the information given, the first half of the journey was traveled at an average speed of 100 km/h, which means the distance covered during this time is (1/2)x km. The time taken for this is given by [tex](1/2)x / 100 = x/200[/tex] hours.
Similarly, the second half of the journey was traveled at an average speed of 60 km/h, which means the distance covered during this time is (1/2)x km.
The time taken for this is given by [tex](1/2)x / 60 = x/120[/tex]hours. Now, we can add the times taken for both halves, which gives us [tex]x/200 + x/120[/tex]hours [tex]= 2/3[/tex]hours. By solving this equation, we arrive at [tex]x = 240 km.[/tex]
Therefore, the total length of the journey is 240 km.

Suppose that XNY are in rational numbers such that x>y. Which of the following inequalities must be true
Answer:
D. 2x > 2y
Step-by-step explanation:
This question illustrates some of the difficulties you can run into with inequalities.
Consider each of the expressions when x = 1 and y = -2. We know that
x > y
1 > -2
__
A. x^2 = 1, y^2 = 4 . . . . x^2 > y^2 is not true
B. -x = -1, -y = 2 . . . . -x > -y is not true
C. 1/x = 1/1 = 1, 1/y = 1/-2 = -1/2 . . . . 1/x > 1/y is true
Now consider x=2, y=1. x > y because 2 > 1, but ...
1/x = 1/2, 1/y = 1 . . . . 1/x > 1/y is not true
D. We know that multiplying the numbers by 2 only stretches them apart on the number line. It does not change their order. For our example, ...
2x = 2, 2y = -4 . . . . 2 > -4 is true
