Devon can have 6 candy bars and 3 sports drinks when he has $15 to spend.
According to the question,
We have the following information:
Devon has $15.
Cost of 1 candy bar = $1
Cost of 1 sports drink = $3
Devon wants to purchase at most 10 items.
It means that the total items should be less than or equal to 10.
Now, we have to spend $15 in such a way that number of items should be less than or equal to 10.
Now, we will look for the number of items for sports drink and change the number of candy bars accordingly.
Let's take 1 sports drink:
$3
We are left with $12. Now, there will be 12 candy bars.
So, this can not satisfy our conditions.
Let's take 2 sports drink:
$6
We are left $9. Now, there will be 9 candy bars. And the number of items is 11.
(This is not satisfying our condition.)
Let's take 3 sports drink:
$9
We are left with $6. Now, there will be 6 candy bars. And the number of items is 9.
This is satisfying all the conditions.
Hence, Devon can have 6 candy bars and 3 sports drinks when he has $15 to spend on snacks.

miles is given by the equation: c=15+2m. If the total cost
was $225, how far was the car driven?
The car was driven 105 miles.
What is rent?
An agreement where a fee is paid for the temporary use of a good, service, or property owned by another is known as renting, sometimes known as hiring, or letting.
In the given example the cost function is, c = 15 + 2m
Where, c is the total cost and m is the number of miles car driven.
The total cost was $225.
So, plug c = $225 in the above equation.
225 = 15 + 2m
210 = 2m
m = 105

The midpoint of UV is (5,−11). The coordinates of one endpoint are U(3,5). Find the coordinates of endpoint V.
Using the mid point, the coordinates of the end point V is (7, -27)
How to find the coordinate using the mid point?A midpoint is a point lying between two points and is in the middle of the line joining the two points.
In other words, the midpoint of a line segment is a point that lies halfway between 2 points.
Therefore, the coordinates of the endpoint V can be found as follows:
using the mid point,
(xₙ, yₙ) = (x₁ + x₂ / 2, y₁ + y₂ / 2)
Therefore,
(5, -11) = (3 + x₂ / 2, 5 + y₂ / 2)
Hence,
5 = 3 + x₂ / 2
cross multiply
10 = 3 + x₂
10 - 3 = x₂
x₂ = 7
Hence,
- 11 = 5 + y₂ / 2
-22 = 5 + y₂
-22 - 5 = y₂
y₂ = - 27
Therefore, the coordinates of V is (7, -27)

Bethany is building a storage trunk. 5ft long, 4ft height and 2ft wide. how much wood is needed to make the trunk
Answer:
76 square feet of wood.
Explanation:
Bethany is building a storage trunk with the following dimensions:
• Length = 5 ft.
,• Height = 4 ft.
,• Width = 2 ft.
We are to determine how much wood is needed to make the trunk.
The amount of wood that will be needed to make the truck is the surface area of the trunk. The storage trunk is in the shape of a rectangular prism.
The surface area of a rectangular prism is found using the formula below:
[tex]\text{Surface Area=2(LW+LH+WH)}[/tex]Substitute the given dimensions:
[tex]\begin{gathered} \text{Surface Area}=2(5\times2+5\times4+2\times4) \\ =2(10+20+8) \\ =2\times38 \\ =76\; ft^2 \end{gathered}[/tex]Bethany needs 76 square feet of wood to make the trunk.
a raised rectangular garden is two feet more than three times as long as it is wide. the depth of the pool is half the width. if the length is 11 feet, what is the volume?
Answer:
49.5ft³
Step-by-step explanation:
If it is 2 ft more than 3 times as long as it is wide then:
l = 3w + 2
which means:
w = (l-2)/3
and:
d = 1/2((l-2)/3)
Now just substitute in 11 for l
w = (11 - 2)/3
w = 9/3
w = 3
d = 1/2((11-2)/3)
d = 1/2(9/3)
d = 1/2(3)
d = 1.5
So the total volume is:
11 * 3 * 1.5

what is the probability that when a coin is flipped six times in a row, it lands heads up every time? (enter the value of probability in decimals. round the answer to three decimal places.)
The probability that the coin lands heads up six times in a row is 0.016
Probability is the term used in mathematics to understand how likely an event is to happen or can also be described as how likely it is that a proposition is true.
It can be determined by dividing the favorable outcomes or events by the total number of outcomes.
As the coin has two sides, the probability that when the coin lands, it lands heads up is determined as follows;
Probability = 1 / 2
Now the probability that the coin lands heads up six times in a row can be calculated as follows;
Probability = (1^6) / (2^6)
Probability = 1 / 64
Probability = 0.015625
Rounding it to three decimal places as follows;
Probability = 0.015625 = 0.016
Therefore, the probability that the coin lands heads up six times in a row is calculated to be 0.016

Answer:
m∠1 = 151°
m∠2 = 29°
m∠3 = 151°
Step-by-step explanation:
We can use knowledge of vertical angles and supplementary angles.
➜ Vertical angles are congruent
➜ Supplementary angles are equal to 180° when added together
Answer:
m∠1 = 151, m∠2 = 29, m∠3 = 151.
Step-by-step explanation:
We know m∠4 is equal to 29. We know m∠4 and m∠2 are equal because they are vertical angles. That means m∠2 is 29. Now, m∠4 and m∠3 equal 180, and m∠2 and m∠1 also equal 180. Since we know m∠4 is 29, you can do 29 + m∠3 = 180. You get m∠3 = 151. Now, m∠1 and m∠3 are also equal because they are vertical angles. That means m∠1 is equal to 151 as well. So your final answers are m∠1 = 151, m∠2 = 29, and m∠3 = 151.

Simplify the left side by adding like terms. I'm going rewrite the equation and group the like terms together.
0.9x + 0.1x + 1.26 - 2.3 = 1.6
