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].

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 area of the circle is 248.035 cm.

Step-by-step explanation:

You can use an online calculator to help you next time if you still get these questions.

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.

C. For better accuracy, we can at least increase the number of trials so we have more data in able for better accuracy.

As Jill did 100 hundred, we think that she will get closer to the actual frequency. As larger the number of trials, the closer we'll get to the expected probability.

Answer: D

Step-by-step explanation: To find the area of a triangle, you multiply the base and the height, then divide by 2, but because there are 4 triangles, you can multiply 12 and 14, and then multiply again by 2. For the square, 12 times 12 is 144, when you add 336 (the area of the triangles) and 144 (the area of the square), you get 480.

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

Answer:

0=1

1=4

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.

Step-by-step explanation:

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.

The volume of the solid generated by the revolution is 33.5 cubic units.

Step-by-step explanation:

It is given that, the diameter of the semi-circle is 4 and it is rotated to one full rotation around its diameter.

A solid generated when a semicircle is being rotated about its diameter is called a "SPHERE".

Therefore, the volume of the solid generated by the revolution is the volume of the sphere.

The formula for volume of the sphere is given by,

Volume of sphere = (4/3)πr³

where, r is the radius and π has the default value of 3.14

Here, the given diameter is 4.

To find the radius = diameter/2

radius = 4/2 = 2.

Now, to calculate volume of sphere substitute r=2 and π=3.14

volume of the sphere = (4/3)×3.14×2³

⇒ (4/3)×3.14×8

⇒ 100.48 / 3

⇒ 33.49 (approximately 33.5)

Therefore, the volume of the solid generated by the revolution is 33.5 cubic units.

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

Question

The following table shows the number of goals that the Texas Sharpshooters scored in each of their 8 hockey  games this season.

Based on this data, what is a reasonable estimate of the probability that the Texas Sharpshooters score exactly  1 goal next hockey game?

3, 4,  1, 4, 1, 1, 2, 1

Answer:

The probability that the Texas Sharpshooters score exactly  1 goal next hockey game is 0.5

Step-by-step explanation:

The topic in question is Experimental probability;

Experimental probabilities deal with the probability of an event happening based on past experiments.

Given

Number of observation, n = 8

To calculate an estimate of the probability that the Texas Sharpshooters score exactly  1 goal next hockey game, we need to count the total occurrence of 1 in the given data

Let p = total occurrence of 1

p = 4

The probability is then calculated as [tex]\frac{p}{n}[/tex]

by substitution;

Probability = [tex]\frac{4}{8}[/tex]

Probability = 0.5

Hence, The probability that the Texas Sharpshooters score exactly  1 goal next hockey game is 0.5

Solution:

Let "x" be the pounds

Company A charges $2.50 per pound plus a  $20 service charge

Cost : 2.50x + 20 ------ eqn 1

Company B charges $4.50 per pound without any service charge

Cost : 4.50x ------- eqn 2

At what weight does it cost the same for both companies?

For both companies to cost the same, eqn 1 must be equal to eqn 2

2.50x + 20 = 4.50x

4.50x - 2.50x = 20

2x = 20

Divide both sides by 2

x = 10

Thus for 10 pounds, both companies cost the same

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.

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.
