Answer: [tex]158cm^2[/tex]

Step-by-step explanation:

You can use the following formula to calculate the surface area of the right rectangular prism:

[tex]SA = 2(wl +lh + hw)[/tex]

Where "w" is the width, "l" is the length, and "h" is the height.

Knowing that this rigth rectangular prism  has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.

Then, the surface of the right rectangular prism is:

[tex]SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2[/tex]

Answer:

Surface area of prism = 158 cm²

Step-by-step explanation:

Points to remember

Surface area of rectangular prism = 2(lb + lh + bh)

Where l - Length, b - Breadth and h - Height

To find the surface area of prism

Here l = 8 cm, b = 3 cm and h = 5 cm

Surface area = 2(lb + lh + bh)

 = 2[(8*3)  + (8 * 5) + (3 *5)]

 = 2[24 + 40 + 15]

 = 2 * 79

 =158 cm²

Surface area of prism = 158 cm²

Answer:

Option C is correct.

Step-by-step explanation:

The formula to find the slope given two points is:

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

We are given points (0,4) and (3,6)

where x₁ = 0 , y₁ = 4, x₂=3 and y₂=6

Putting values in the formula:

[tex]slope = \frac{6-4}{3-0} \\slope = \frac{2}{3}[/tex]

So, slope is 2/3

Since the slope of line to be found is parallel to line L. So both lines have the same slope.

Slope of line parallel to line L = 2/3

Option C is correct.

Answer:You haven't attached a picture but this is what your line should look like

Step-by-step explanation:

For this equation you simply have to graph it.

First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.

Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.

Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.

Answer:

250 batches of muffins and 0 waffles.

Step-by-step explanation:

-1

If we denote the number of batches of muffins as "a" and the number of batches of waffles as "b," we are then supposed to maximize the profit function

P = 2a + 1.5b

subject to the following constraints: a>=0, b>=0, a + (3/4)b <= 250, and 3a + 6b <= 1200. The third constraint can be rewritten as 4a + 3b <= 1000.

Use the simplex method on these coefficients, and you should find the maximum profit to be $500 when a = 250 and b = 0. So, make 250 batches of muffins, no waffles.

You use up all the dough, have 450 minutes left, and have $500 profit, the maximum amount.

Answer:

The answer is A.

Step-by-step explanation:

We only have to test one coordinate to find the answer. The original coordinate for N is (-1, -1). Using the formula, N' is (0, -2).

You see, it's quite easy. All you need to do is find the coordinates of FNQ, then add the 1 to the x values and subtract 1 from the y values as stated in the translation rule.  

However, in your case, you don't have numbers on your graph but you can easily draw some. Be mindful of the quadrants.

Let's try out point F just for gags.

F = (3, 3)  

(Technically you only need one point to determine the answer.)

Now, apply rule: x + 1, y - 1

(3, 3) becomes (4, 2)  

Now, which multiple choice answer contains that specific point for F?  

Choice A.

Answer:

The statement most accurately describes the relationship between

segments of the triangles formed by the beam is AC < DF

Step-by-step explanation:

* Lets study the figure to answer the problem

- There are two triangles ABC and DEF

- AB = BC

- DE = EF

- AB = DE

∴ AB = BC = DE = EF

- m∠ABC = 45°

- m∠DEF = 60°

∵ The measure of angle ABC is smaller than the measure of

   angle DEF

∴ The opposite side to the angle ABC is shorter than the opposite

   side of angle DEF

∵ AC is the opposite side to angle ABC

∵ DF is the opposite side to angle DEF

∴ AC is shorter than DF

∴ DF > AC

∴ AC < DF

* The statement most accurately describes the relationship between

  segments of the triangles formed by the beam is AC < DF

Final answer:

After applying a $5 coupon to his $16, Tyler is left with $11. Given the cost of one bottle of olive oil is $7, Tyler can only purchase 1 bottle because he cannot buy a fraction of a bottle.

Explanation:

The student's question involves basic arithmetic operations and budget management, which falls under the subject of Mathematics. Tyler can use the $5 coupon to reduce the total cost of his purchase. To determine how many bottles of olive oil he can buy, we need to subtract the coupon value from the amount of money he has:

Now, we divide the amount left by the cost of a single bottle of olive oil:

Since Tyler cannot buy a fraction of a bottle, he can buy only 1 bottle of olive oil with the money he has after applying the $5 coupon.

Hello There!

Dividing a fraction is the same thing as multiplying by its reciprocal.

This means that [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{5}{12}[/tex] is the same as multiplying [tex]\frac{3}{4}[/tex] by [tex]\frac{12}{5}[/tex].

So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

HAVE A GREAT DAY!

Answer:   [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

When you divide fractions you can multiply the first fraction by the reciprocal of the second fraction.

To find the reciprocal of the fraction, you need to flip it. Then the original denominator will be the new numerator and the original numerator will be the new denominator.

Then, the reciprocal of the fraction [tex]\frac{5}{12}[/tex] is:

[tex]\frac{12}{5}[/tex]

Therefore:

[tex]\frac{3}{4}[/tex]÷[tex]\frac{5}{12}= \frac{3}{4}* \frac{12}{5}[/tex]

Answer:

x = 1.25

y = 0.75

Step-by-step explanation:

Let $x be the cost per pound of apples

Let $y be the cost per pound of bananas

5x + 3y = 8.5  --- (1)

3x + 2y = 5.25  --- (2)

From (1),

3x + 1.8y = 5.1  --- (1a)

Subtract (1a) from (2),

(3x + 2y) - (3x + 1.8y) = 5.25 - 5.1

3x - 3x + 2y - 1.8y = 0.15

0.2y = 0.15

y = 0.15 / 0.2 = 0.75

x = [ 5.25 - 2(0.75) ] / 3 = 1.25

Step-by-step explanation:

hihi, so given a statistic, a sample standard deviation, and the sample size, we can create a 99% confidence interval for this distribution. Given the equations for confidence interval and Margin of Error, all we have to calculate initially is t* (invT(.995, 85-1)) and Standard error (34/sqrt(85)). Once we have these numbers, it's as easy as plugging in and doing some simple calculations to reaching our upper and lower fences of our interval. (136.28, 155.72). Any value below the lower fence or any value above the upper fence is not in our interval

The 99% confidence interval for the given random sample is between 136.5 and 155.5. The critical value for a 99% of confidence interval is 2.58.

The formula for the confidence interval is

C.I = μ ± Margin error

Where Margin error = critical value × Standard error and μ - mean

Standard error = δ/[tex]\sqrt{n}[/tex]

δ - standard deviation and n is the sample space.

The critical value (z) is obtained from the percentage confidence interval table.

Given that,

Sample space n = 85

Mean μ = 146 and δ = 34

Calculating the standard error:

S.E = δ/[tex]\sqrt{n}[/tex]

      = 34/√85

      = 3.68

The critical value for the 99% of the confidence interval is 2.58

Calculating the Margin error:

Margin error = 2.58 × 3.68

                     = 9.49

                     = 9.5

Then the 99% of the confidence interval is calculated as follows:

C.I = μ - Margin error (lower interval)

    = 146 - 9.5

    = 136.5

C.I = μ + Margin error (upper interval)

    = 146 + 9.5

    = 155.5

Thus, the 99% confidence interval is 136.5 - 155.5.
