Find the measure of missing angles

A sketch of the required prism is as shown below.

In this question,

Josh is building a kaleidoscope using PVC pipe, cardboard, bits of colored paper, and a 12 -inch square mirror tile.

While making a kaleidoscope, the mirror tile is to be cut into strips and arranged to form an open prism, with a base like that of an equilateral triangle.

We need to make a sketch of the prism, giving its dimensions

As the base of the prism formed is an equilateral triangle, the mirror tile must be cut into three rectangular strips of equal width.

So, the width would be 12 ÷ 3 = 4 inches

The original tile is a 12-inch square, the length of each side of the square is 12 inches.

So the each rectangular strip will be 12 inches by  4 inches.

i.e., the length = 12 inches and width = 4 inches

Therefore, a sketch of the prism is as shown below.

Step-by-step explanation:

replace x with -7

f(-7) = 5 - (-7)

f(-7) = 5 + 7

f(-7) = 12

The value of -17-x is A. -13.

We are given the expression. To find the result, we need to solve the first expression. This will give the value of x. Further, we will be using the value of x to find the value of another expression.

-2 + x = -6

Shifting the value of -2 to the Right Hand Side of the equation

x = -6 + 2

Performing subtraction on Right Hand Side of the equation

x = -4

Now, keeping the value of x in second expression -

Value = -17 -(-4)

As there are two negative signs, the number 4 will be represented with positive sign

Value = -17 +4

Performing subtraction

Value = -13

Hence, the value of expression is A. -13.

The supplementary angles are 60 degrees and 120 degrees

Two angles are said to be supplementary when their measure add up to 180 degrees.

Therefore, if x and y are supplementary angles,

x + y = 180

x represent the degree measure of the​ angle's supplement.

The measure of the angle is two times greater than its supplement.

Therefore, the algebraic expression of the angles is as follows:

x + 2x = 180

3x = 180

divide both sides by 3

3x / 3 = 180 / 3

x = 60

Therefore, the supplementary angles are 60 degrees and 120 degrees.

When you are given two sides but no measurement of the angle, such as a = 15 and b = 15, we can create an infinite number of triangles.

For instance:

How many different triangles can be made if we have side lengths of 15 and 15 and an angle value of 0 to 360 degrees?

Using a protractor, make one of the triangles with sides of 25 metres and 21 metres, an angle of 12 degrees, and a third side that can be changed to your preferred length. You've constructed a triangle.

Similar to this, we can create a completely different triangle by varying the third side's length and angle measurement.

It's crucial to remember that you select the side lengths and angle. This implies that you might choose differently. You may create an infinite number of distinct triangles by using the same angles.

As a result, we can make an infinite number of triangles using just one angle and one side length.

Answer:

(1,3), (2,2), (3,1), (4,0), (-1,5), (-2,6), (-3,7), (-4,8), (-5,9), & (-6,10)

Step-by-step explanation:

First, solve to alter the equation into a slope form instead of in standard form.

x+3y=12

Because x represents the slope, we need to transfer it to the other side of the equation. By subtracting it, it'll allow the equation to only have 3y on the left side of the equation and x will become negative x which will be added on to the 12 on the right side.

x+3y=12

-x       -x

+3y=-x+12

3y=-x+12

Next, you would divide the 3 underneath the y and the number 12 to allow the 3y to become y because y needs to be isolated in order for the slope intercept formula to work.

3y divided by 3 equals 3 and 12 divided by 3 is 4.

3y/3=-x+12/3

The final equation would look as follows:

y=-x+4

Hence, the y-intercept is 4 and the slope is -1.

You would then plot the origin coordinate of (0,4) and either go down one and right one or up one and left one; either way, you'll receive a negative slope looking like this: \

Some points on the graph would be: (1,3), (2,2), (3,1), (4,0), (-1,5), (-2,6), (-3,7)

The number of pensioners in the sample is 40.

Given,

Visitors to a cinema are either adults, children, or pensioners.

The ratio of children to adult visitors is 1:2.

The ratio of adults to pensioners is 3:4.

A stratified sample of 85 is to be taken from the cinema visitors.

We need to find out how many pensioners should be in the sample.

Example:

Out of 10 pens, the ratio of the red and blue pens is a:b

The number of blue pens = [ b / (a + b) ] x 10

The number of red pens = [ a / (a + b) ] x 10

We have,

Total number of visitors = 85

children:adult  = 1:2

adults:pensioners = 3:4

Here,

Let,

The number of children be C.

The number of adults be A.

Number of Pensioners be P.

Now,

1C : 2A

    : 3A : 4P

3C : 6A : 8P

Now,

3C + 6A + 8P = 85

This means 8 is the ratio of pensioners.

= 8 / (3 + 6 + 8) x 85

= (8 / 17)x 85

= 8 x 5

= 40

Thus the number of pensioners in the sample is 40.

Answer:

The water cooler can hold approximately 23,6L

The correct answer from each drop-down menu is as follows:

A quadratic function can be defined as a mathematical expression that can be used to define and represent the relationship that exists between two or more variable on a graph.

In Mathematics, the graph of any quadratic function is parabolic because it is a u-shaped curve. For the given quadratic function, the graph is a downward parabola because the coefficient of x² is negative.

Therefore, function p is a quadratic function.

When the length of the tomato patch is 8 feet, the area of the bell pepper patch is given by:

p(x) = -0.5x² + 6x

p(8) = -0.5(8)² + 6(8)

p(8) = -0.5(64) + 48

p(8) = -32 + 48

p(8) = 16 square feet.

From the graph, we can logically deduce that the maximum possible area occurred at x = 6 feet. Thus, maximum possible area is given by:

p(x) = -0.5x² + 6x

p(6) = -0.5(6)² + 6(6)

p(6) = -18 + 36

p(6) = 18 square feet.

This is because all 3 sports are needed for the triathlon

There are 35 swimmers total. 9 of which are also cyclers (but not runners), and there are 13 swimmers who are also runners (but not cyclers)

That leaves 35-9-13-x people who are swimmers only. I'll leave this expression un-simplified so you can see where the numbers are coming from. Take note of where I'm placing this in the venn diagram below.

There are 32 cyclers. Of this group, 9 are swimmers (but not runners) and 11 are runners (but not swimmers). That leaves 32-9-11-x people who are cyclers only.

There are 38 runners. Of this group, 13 are swimmers (but not cyclers) and 11 are cyclers (but not swimmers). That leaves 38-13-11-x people who are runners only.

All of these values are honestly hard to keep track of. This is why a visual approach using a Venn Diagram is recommended. See the diagram below.

The idea is that every value in the diagram then adds up to the 58 total attendees. This helps form the equation needed to solve for x.

Such an equation is possible because each attendee participates in at least one of the sports mentioned. No values will be outside of all three circles at the same time.
