Answer:

height of tree = 7.68 m

Step-by-step explanation:

ΔABC and      Δ A D E  are similar .  In similar triangles, corresponding sides are always in the same ratio

The height of tree is 6.08 m.

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value.

Given:

Height of Erin =1.60m

Erin's shadow height = 1.25 m

Tree's shadow height = 4.75 m

Tree's height = x

1.60/1.25 = x /4.75

1.25x = 1.60*4.75

1.25x= 7.6

x= 7.6/1.25

x= 6.08 m

Hence, the height of tree is 6.08 m.

Answer:

Yes, the percent discount (18%) is the same for both levels of membership

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Membership Level  Individual Family

Original Price              50.00      75.00

Discounted  Price        41.00      61.50

2. Is the percent discount  the same for both levels of membership?

A. Let's calculate the discount for the individual membership level, this way:

Discount percent = 100 - (41/50 * 100)

Discount percent = 100 - 82

Discount percent = 18%

B. Let's calculate the discount for the family membership level, this way:

Discount percent = 100 - (61.50/75 * 100)

Discount percent = 100 - 82

Discount percent = 18%

Yes, the percent discount (18%) is the same for both levels of membership.

The volume of the tent is 46.67 ft³

Explanation:

Given that the rectangular base is 35 square feet.

The height of the pyramid is 4 feet.

We need to determine the volume of the tent.

The volume of the tent can be determined using the formula,

[tex]Volume=\frac{1}{3} Bh[/tex]

where B = 25 and h = 4

Substituting these values in the above formula, we get,

[tex]Volume = \frac{1}{3} (35\times 4)[/tex]

Multiplying the numerator, we get,

[tex]Volume= \frac{140}{3}[/tex]

Dividing, we get,

[tex]Volume =46.6667 \ ft^3[/tex]

Rounding off the value to the nearest hundredth, we have,

Volume = 46.67 ft³

Therefore, the volume of the tent is 46.67 ft³

Using the Remainder Theorem, the remainder when the polynomial 3x³-14x²-14x+3 is divided by 3x + 5 is found to be 7 after evaluating the dividend at the root of the divisor, which is -5/3.

The question asks for the remainder when the polynomial 3x³-14x²-14x+3 is divided by 3x + 5. To find the remainder, you can perform polynomial long division or use the Remainder Theorem. Since the divisor is linear, the Remainder Theorem states that the remainder is equal to the value of the dividend evaluated at the root of the divisor. The root of 3x + 5 is -5/3. Plugging this value into the dividend:

(3×(-5/3)³ - 14×(-5/3)²- 14×(-5/3) + 3).

After calculating, we find that the remainder is 7. Thus, when the given polynomial is divided by 3x + 5, the remainder is 7.

Surface area of rectangular prism is [tex]238\ mm^{2}[/tex] .

Step-by-step explanation:

We have net for a rectangular prism.  Surface area of rectangular prism is given by:

Step 1:

We need to calculate area of material needed as shown in figure above, Let's first concentrate on vertical rectangle have width 11 mm and length ( 5 + 4 + 5 +4 ) mm = 18 mm. We know that ,

area of rectangle = length × width

⇒ [tex]area = length(width)\\area = 11(18)\\area = 198\ mm^{2}[/tex]

Step 2:

Now only two horizontal small rectangles are left with dimensions as length =  4 mm and width = 5 mm.

∴ area of rectangle = length × width

⇒ [tex]area = length(width)\\area = 4(5)\\area = 20\ mm^{2}[/tex]

Also there are Two rectangles , so

total area = [tex]2(area) = 2(20) = 40\ mm^{2}[/tex]

Step 3:

Adding area of step 1 and 2 we get : [tex]198\ mm^{2} + 40\ mm^{2} = 238\ mm^{2}[/tex]

∴ Surface area of rectangular prism is [tex]238\ mm^{2}[/tex].

The form

[tex]y=mx+q[/tex]

is called slope-intercept form. In particular, the coefficient [tex]m[/tex] is the slope, and the constant [tex]q[/tex] is the y-intercept.

In your case, the coefficient of [tex]x[/tex] is [tex]-3[/tex], so that would be your slope.

And your constant term is [tex]8[/tex], so that is your y-intercept.

Step-by-step explanation:

Angle 1 is congruent to angles 3, 5, and 7. We know this because vertical angles are congruent (angle 3), as are corresponding angles (angle 5) and alternate exterior angles (angle 7).

Angle 3 is congruent to angles 1, 5, and 7. We know this because vertical angles are congruent (angle 1), as are corresponding angles (angle 7) and alternate interior angles (angle 5).

Angle 4 is congruent to angles 2, 6, and 8. We know this because vertical angles are congruent (angle 2), as are corresponding angles (angle 8) and alternate interior angles (angle 6).

Angle comparison requires measuring each angle with a protractor. Angles are congruent if their measurements are equal. This concept is used in geometry and other fields like physics.

Your question involves identifying and comparing angles, which is a topic in geometry, a branch of mathematics. When determining congruent angles, you need to look at the measure of the angles. Two angles are congruent if they have the exact same measure.

In the problem you provided, to find the congruent pairs, you would have to measure each angle provided with a protractor. If the measure of the angles is equal, then those angles are congruent.

Remember that in a right triangle, the angles are 90 degrees, 45 degrees and 45 degrees. The angles of a straight line sum up to 180 degrees. These are valuable skills which you can use to aspects of physics, specifically when dealing with vectors as you mentioned tail-to-head addition of vectors and the angles between them.

The solution to the system of equations -3x-2y=36 and 3x-5y=6 is x = -8 and y = -6. This was achieved by adding the equations together to eliminate x, then solving for y, and substituting y into the first equation to solve for x.

To find a solution to the system of equations, you can use the method of addition (also known as elimination). In this case, these equations are designed in a way that allows you to simply add them together. Having the equations: -3x-2y=36 and 3x-5y=6, if you add these two equations together, the x variable will cancel out, leading to:  -2y - 5y = 36 + 6, simplifying this yields -7y = 42. Finally, to solve for y, you divide both sides by -7, yielding y = -6. Now that we have the value for y, we can substitute it into the first equation to solve for x: -3x - 2(-6) = 36 --> -3x + 12 = 36 --> -3x = 24. Dividing both sides by -3, we get

x = -8. Therefore, the solution to the system of equations is x = -8 and y = -6.

Answer:

Step-by-step explanation:

A.  It says he will get to sit in the front if the number is even

There are 6 sides, three of which are even numbers (2,4,6). So the probability of rolling an even number is 3/6 = 1/2.

Let's make p = 1/2

Jack will get his way half of the time, so we expect him to get the front seat half of the time

If we're talking about 20 days, then n = 20 and

n*p = 20*(1/2) = 20/2 = 10

meaning that Jack would, on average, get the front seat 10 times out of the 20 total.

B. Similar to A

n=100

The probability is still the same because rolling an odd number (1,3,5) is still going to happen 3/6 = 1/2 of the time.

so: n*p means 100 days*1/2 which is 100/2=50 days

Jill get to sit in the front 50 out of the 100 days.

Answer:

No units

Step-by-step explanation:

The cost function is given by;

[tex]C(x)=x^2-20x+35[/tex]

To find the units manufactured at a cost of $5,560

We equate the C(x) to 5560 and solve for x.

[tex]x^2-20x+35 = 5560[/tex]

[tex]x^2-20x+35 - 5560 = 0[/tex]

[tex]x^2-20x - 5525= 0[/tex]

The discriminant of this equation is negative.

That is,

[tex]d = {( - 20)}^{2} - 4 \times 1 \times - 5560 \: < 0[/tex]

Hence the equation has no real roots.

This means no units can be produced at $5,560

Answer:

2=7

Step-by-step explanation: Just substitute the 'x' in y=3x+1 with the number in the table (i.e 0, y=3*0+1= 1) and so forth

The table in the image is a table for the equation y = 3x + 1. It shows the values of y for different values of x.

Here is the table in text format:

x y

0 1

1 4

2 7

We can check that the values in the table are correct by substituting the values of x into the equation y = 3x + 1.

For example, if we substitute x = 0, we get y = 3(0) + 1 = 1, which is the value in the table.

The table can be used to graph the equation y = 3x + 1.

To do this, we plot the points (x, y) in the table on a coordinate plane.

The points will form a straight line.

Here is a graph of the equation y = 3x + 1:

graph of y = 3x + 1

graph of y = 3x + 1

The y-intercept of the graph is 1.

This means that the line passes through the point (0, 1).

The slope of the graph is 3.

This means that for every 1 unit that x increases, y increases by 3 units.

The graph can be used to solve for y for any given value of x.

For example, if we want to solve for y when x = 3, we can find the point on the graph where x = 3 and read off the corresponding value of y.

The point is (3, 10), so y = 10 when x = 3.
