ANSWER

C. 145.75 yd²

EXPLANATION

First we need to calculate the area of the four triangular faces.

The lateral surface area

[tex] = 4 \times \frac{1}{2} \times 5.3 \times 11.1[/tex]

[tex] = 117.66 {yd}^{2} [/tex]

The area of the base is

[tex] = 5.3 \times 5.3[/tex]

[tex] = 28.09[/tex]

To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.

Therefore the total surface area is

[tex] = 117.66 + 8.09 = 145.75 {yd}^{2} [/tex]

Answer: Option C.

Step-by-step explanation:

To calculate the surface area of the right square pyramid, you need to use the following formula:

[tex]SA=\frac{1}{2}(4s)(l)+(s^2)[/tex]

Where  "s" is the length of any side of the base and "l" is the slant height.

You can identify in the figure that:

[tex]s=5.3yd\\l=11.1yd[/tex]

Therefore, substituting these values into the formula, you get this result:

[tex]SA=\frac{1}{2}(4(5.3yd))(11.1yd)+((5.3yd)^2)\\\\SA=145.75yd^2[/tex]

Answer:

29 + n

Step-by-step explanation:

To increase 29 by n, we add n to 29. Then we get 29 + n.

Answer:

29 + n

Step-by-step explanation:

When we increase a number by another number, we're performing the operation of addition, so the phrase here would translate to the expression 29 + n.

Step-by-step Answer:

Gap must be a maximum of 0.005 inches, and uniform all around.  Round out with a sizing tool if necessary.

When brazing, the clearance gap between pipe and fitting should be between 0.002 and 0.006 inches.

This clearance gap is important to allow the brazing material to flow via capillary action and to create a strong, sealed joint. The exact clearance can vary depending on the materials and the application, but staying within this range is a good practice.

For brazing larger diameter pipes and fittings, a slightly larger gap may be acceptable, but generally it is best to maintain the smallest gap that will still allow for proper capillary action of the filler metal.

Answer: The answer to the first one is 99m. The answer to the second one is 62cm.

Step-by-step explanation: You would multiply 63 by 2 to get 126. You would subtract 126 from 324 to get 198. Then you would divide 198 by 2 which would equal 99 which is your answer.

You would divide 5828 by 94 to get 62 wich would be your answer.

Answer:

  10 and 14

Step-by-step explanation:

You need only check the answers to see which one satisfies the problem requirements. The differences between the second and first numbers are ...

  8, 4, 2, -6

Only one pair has the second number 4 more than the first: 10 and 14.

_____

Since you are given variable definitions, perhaps you're expected to write and solve equations.

  a + b = 24 . . . . . the sum of the two numbers is 24

  -a +b = 4 . . . . . . the second number is 4 more than the first

Adding these two equations gives ...

  (a +b) +(-a +b) = (24) +(4)

  2b = 28 . . . . .  simplify; next, divide by 2

  b = 14 . . . . . . .  identifies 10 and 14 as the correct answer

Answer:

10 14

Step-by-step explanation:

I'm not the best at math, but I tried.

x= the amount of months passed

The question asks for the population of fleas in 1 year, and 1 year = 12 months, then x would equal 12 months

Therefore, you substitute that x with 12

f(x)=250(2^x)-------f(x)=250(2^12)

Now you can solve that part of the problem:

2 to the power of 12= 4096

f(x)=250(4096)

now multiply that:

250×4096= 1024000

The answer is C. 1024000

The answer is 1,024,000 fleas.

The function f(x)=250(2^x) gives the population of fleas after x months. To find out how many fleas there will be after 1 year, substitute x=12 into the function:
f(12) = 250(2^12) = 250 * 4096 = 1,024,000 fleas.

According to the information, it can be inferred that the current credit score for Esteban is 730 because he has not used more transactions than eleven of his credit score.

A credit score is a term that refers to an index that is intended to predict the chances that you will repay a loan on time.

This takes into account different factors related to your economy, so it is likely that the more movement of money you have, your score will be higher.

Based on the foregoing, it can be inferred that Esteban's score dropped because he has not made important transactions in recent months. Additionally, it has no recent transaction history.

Hyperbola:

[tex]x^2-y^2-8x+6y-1=0[/tex]

Step-by-step explanation:

the given hyperbola has equation:

[tex]x^2-y^2=8[/tex]

This is an equation of a hyperbola centered at the origin.

This hyperbola is translated so its center is now at T(4,3)

[tex](x-4)^2-(y-3)^2=8[/tex]

We expand to get:

[tex]x^2-8x+16-(y^2-6y+9)=8[/tex]

Answer: True

Step-by-step explanation:

 We know that the quadratics polynomials have this form:

[tex]f(x)=ax^2+bx+c[/tex]

You need to remember that the degree of a polynomial is given by its highest exponent.

You can observe in the quadratic polynomial [tex]f(x)=ax^2+bx+c[/tex] that the highest exponent is "2", which is the exponent of the term [tex]ax^2[/tex]

Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.

Then, you can say that a quadradic polynomial has degree 2.

3.4(x+1.58)= - 11.288

Step 1: Distribute 3.4 to the numbers inside the parentheses (x+1.58)

3.4x + (3.4×1.58)= - 11.288

3.4x + 5.372 = -11.288

Step 2: Bring 5.372 to the right side by subtracting it to both sides

3.4x + (5.372 - 5.372 ) = (-11.288 - 5.372)

3.4x + (0) = (-16.66)

3.4x = -16.66

Step 3: Isolate x by dividing 3.4 to both sides

[tex]\frac{3.4x}{3.4}  = \frac{-16.66}{3.4}[/tex]

x = -4.9

Answer:

18 yds

Step-by-step explanation:

Let the length and width be L and W respectively.

Then L· W = area = 72 yd², so that L = (72 yd²) / W.

But also L = 3W + 6 yd.  Subbing this into  L· W = area = 72 yd², we get:

(3W + 6) · W = 72, or

3W² + 6W - 72 = 0.  Since all  four terms are evenly divisible by 3, we get:

W² + 2W - 24 = 0, which factors as follows:

(W + 6)(W - 4) = 0.  Then W + 6 = 0, or W = -6 (makes no sense for a length), and W - 4 = 0 yields W = 4 yds.

If the shorter side is of length 4 yds, then the longer side is of length

L = 3(4 yds) + 6 yds = 18 yds

Answer:

18 yd

Step-by-step explanation:

(3x + 6) * x = 72

Use the distributive property

3x^2 + 6x = 72

3x^2 + 6x - 72 = 0

3(x^2 + 2x - 24) = 0

X^2 + 2x - 24 = 0

X can equal -6 and 4.

4 only works for this problem

4 * 3 = 12

12 + 6 = 18

So, the answer is 18 yd.

Let’s check our work.

3 * 4 = 12

12 + 6 = 18

18 * 4 = 72

So, we know for a fact that the longer side is 18 yd long.

The answer is:

The total time traveled is equal to 9 hours.

To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.

So, we need to write two equations:

Let be "x" the speed of the cabin cruiser (12 mph in still water)

Let be "y" the speed of the current (4 mph).

Then,

For the travel against the current (upstream), we have:

[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]

For the travel with the current (downstream), we have:

[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]

Also, we know that the speed of the cruise traveling in still water is equal to 12mph.

So,

Calculating the time traveled upstream, we have:

[tex](x-4mph)*t_{upstream}=48miles[/tex]

[tex](12mph-4mph)*t_{upstream}=48miles[/tex]

[tex](8mph)*t_{upstream}=48miles[/tex]

[tex]t_{upstream}=\frac{48miles}{8mph}=6hours[/tex]

Calculating the time traveled downstream, we have:

[tex](x+4mph)*t_{downstream}=48miles[/tex]

[tex](12mph+4mph)*t_{downstream}=48miles[/tex]

[tex](16mph)*t_{downstream}=48miles[/tex]

[tex]t_{downstream}=\frac{48miles}{16mph}=3hours[/tex]

Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:

[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]

Hence, we have that the total time traveled is equal to 9 hours.

In the stem and leaf plot, we have to express the numbers as follows

50 53 65 64 75 77 78 82 84 85 86 87 87 90 91 92 93 94 96 97 99
