It's 13.5 because you put them in order and then you have 13 and 14 you add them together and then divide by 2

So you first have to order them least to greatest, which would be : 8 , 9 , 13, 14 , 15, 16. Since the number of numbers is even, average the 2 middle numbers. This is 13 + 14 divided by 2 or 13.5.

Let the necessary amount of water be x.  Then (1.00)(1 gallon antifreeze) = 0.40(x+1 gallon), or 1 = .40x + .40.  Combining like terms:  0.60 = 0.40x.

Then x = 0.60 / 0.40 = 1.5.

Adding 1.5 gallons of water to that 1 gallon of pure antifreeze results in 2.5 gallons of 40% antifreeze.

To create a solution that is 40% antifreeze, you would add .6 gallons of water to 1 gallon of pure antifreeze, using a ratio to determine this.

To find out how much water should be added to a gallon of pure antifreeze to create a solution that is 40% antifreeze, you would use a ratio. We find that 40% of a gallon of antifreeze is .4 gallons, as 1 gallon is equivalent to 100%. If this .4 gallons represents 40% of our final solution, that means the remaining 60% must be water.

Next, we set up a ratio. If .4 gallons is 40%, then x gallons is 60%. This gives us .4/40 = x/60. Simplifying that equation, we find that x equals .6 gallons.

In conclusion, to get a solution that is 40% antifreeze and 60% water, you need to add .6 gallons of water to 1 gallon of antifreeze.

The answer is -10

As the given equation is

Answer:

Select the most appropriate unit for the measure of time that the graph represents.

A.  hours

B.  days

C.  weeks

They are always on a coplanar

Answer:

Perpendicular lines are always coplanar.

Step-by-step explanation:

Coplanar lines are lines drawn on the same plane. So whenever you have

perpendicular lines (i.e lines at right angle to each other), they are always coplanar. This is because they are drawn on the same plane.

Answer choice 1.

Final answer:

To find the measure of angle KNL, we need to add the given upward-left obtuse angle and the downward-right acute angle. Simplify the expression to find the measure of angle KNL.

Explanation:

The question is asking for the measure of angle KNL. We are given that lines MK and JL intersect at their midpoint N. We are also given that the upward-left obtuse angle is labeled as (5x+2) degrees and the downward-right acute angle is labeled as [3(x+14)] degrees.

To find the measure of angle KNL, we need to add the two given angles together since angle KNL is formed by the intersection of these two lines. So, we have:

m angle KNL = (5x+2) + [3(x+14)]

Simplifying the expression, we get:

m angle KNL = 5x + 2 + 3x + 42

m angle KNL = 8x + 44

Therefore, the measure of angle KNL is 8x + 44 degrees.

Final answer:

The measure of angle m∠KNL is 136°.

Explanation:

The question asks for the measure of the angle m∠KNL. It provides some information about the angles formed by the line segments MK and JL. The upward-left obtuse angle is labeled as (5x+2)° and the downward-right acute angle is labeled as [3(x+14)]°. To find m∠KNL, we need to solve for x and substitute it into one of the angle expressions.

We know that the sum of the measures of the angles in a triangle is 180°. Since m∠KNL is opposite the obtuse angle (5x+2)°, we can write the equation as: (5x+2)° + [3(x+14)]° + m∠KNL = 180°.

Simplifying the equation by expanding the brackets and combining like terms, we get: 5x + 2 + 3x + 42 + m∠KNL = 180. Combining like terms further, the equation becomes: 8x + m∠KNL + 44 = 180. To isolate m∠KNL, we subtract 44 from both sides, resulting in: 8x + m∠KNL = 136. Therefore, the measure of angle m∠KNL is 136°.

Solution

g(x) = 2[tex]x^{2}[/tex] - 11x

Plugging in x = -1 in g(x), we get

g(-1) = 2[tex](-1)^{2}[/tex] - 11(-1)

For #10

x=2     w(x)= 5

x=0     w(x)=-9

x=1     w(x)=-1

x=4    w(x)=7

To get these answers, you must use the p(x) table. When x=2, p(x)=6. So you would substitute p(x) for 6 and solve. That would be what you would do for the rest of teh problems.

For #12, the answer would be 5x^2+15x+5

Just mutiply the areas of the out side and inside and subtract them

the answer's 41 degrees. If the total sum of the angles in a triangle is 180, and a right angle is 90, and the other angle is 49 degrees. 180-90-49=41, so that's your answer! Hope I helped you.

i believe the answer would be 41 because the triangle is 180 degrees and so you would add the 49 and the 90 degree angle then subtract that from 180, then you get 41.

Last year a man earned 19,200. This year his salary increased to 20,736. What was the percent of his increase ?

Solution

Here we have to use the formula.

Percentage of increase =[tex]\frac{Increase}{Original number}  *100[/tex]

Increase in earning = 20, 736 - 19,200 = $1536

Original number = 19,200

Now plugin these values into the formula, we get

Percentage of increase = [tex]\frac{1536}{19200} *100 = \frac{153600}{19200} = 8[/tex]%

The answer is 8%

Hope you will understand the steps.

Hey there!!

Shape given - Cylinder

In order to find the amount of gas the vessel can hold, we will have to find the volume of the cylindrical vessel.

How do we find the volume of a cylindrical vessel?

The formula : πr²h

Where ' r ' is the radius and ' h ' is the height.

The height is given by 9 feet.

The diameter is given by 6 feet. This is the tricky part, we will have to use the radius not the diameter.

The diameter = Radius + Radius

6 = radius + radius

6 = 2 × radius

Dividing 2 on both sides

6 ÷ 2 = radius

Hence, the radius is 3 feet.

We have :

Height = 9 feet

Radius = 3 feet

Volume : π ( 3 )² ( 9 )

... π × 9 × 9

... π × 81

... 3.14 × 81

... 254.34 feet³

Hence, the amount could be held in the cylindrical is 254.34

Hope my answer helps!!

Answer:

[tex]y\geq \frac{1}{2}x[/tex]

Step-by-step explanation:

To find the inequality represent by the graph, we first must find the linear equation that represents that line.

So, in first place, we find the slope of the line, using two point (0,0) and (2,1):

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }=\frac{1-0}{2-0}=\frac{1}{2}[/tex]

Now, using one point, the slope and the slope-point formula, we find the linear expression

[tex]y-y_{1}=m(x-x_{1})\\y-0=\frac{1}{2}(x-0)\\ y=\frac{1}{2}x[/tex]

Then, with the linear expression, we just need to take a test point form the shaded area and evaluate the expression, the point is gonna be (0,1):

[tex]y=\frac{1}{2}x\\1=\frac{1}{2}(0)\\ 1=0[/tex]

We know that 1 is more than zero, this means that the right inequality sign is [tex]\geq[/tex], due to the relation of the numbers, and because line is solid.

Therefore, the inequality is

[tex]y\geq \frac{1}{2}x[/tex]

Simplify. Combine like terms:

Answer: 10.8 yards

Step-by-step explanation:

Given: Total fabric Jennifer has = 84.5 yards

Total identical curtains she made = 6

Remaining fabric = 19.7 yards

Thus, fabric used fro 6 curtains = [tex]84.5-19.7=64.8\ yards[/tex]

Now, fabric she use for each curtain = [tex]\frac{64.8}{6}[/tex] yards

Thus, fabric she use for each curtain= 10.8  yards

Hence, Jennifer use 10.8 yards fabric per curtain.

Answer:

10.8 yards

Step-by-step explanation:

84.5 - 19.7 = 64.8

64.8 / 6 = 10.8 yards

Jennifer can use 10.8 yards per curtain.

The answer would be 12.5 ft

This is because you know that if you cast a shadow of 8 feet and you are 5 feet then a lamp post that is 12.5 feet will have a 20 foot shadow.

To solve for the height of the lamppost, we can use the equation h = (5/8) * 20, derived from the ratio of height to shadow length across similar triangles.

To determine the height of the lamppost using the shadow lengths, we apply the concept of similar triangles. Since the student's height and shadow form a right-angled triangle, and the lamppost and its shadow do as well, the two triangles are similar by the angle-angle similarity postulate. Thus, the ratio of the height to the shadow length is constant for similar triangles created by an object and its shadow under the same lighting conditions.

The relationship for the student can be expressed as student's height / student's shadow length, which is equal to 5 feet / 8 feet. For the lamppost, the relationship can be described as height of lamppost (h) / lamppost's shadow length, which is h / 20 feet. Therefore, the proportion can be set up as:

5/8 = h/20

Multiplying both sides of the proportion by 20 gives us the equation to solve for h, the height of the lamppost:

h = (5/8) * 20
