Triangle ABC ~ Triangle DEF. Use The Image To Answer The Question.Determine The Measurement Of EF. EF

Answers

Answer 1

Answer:

EF = 2.37

Step-by-step explanation:

It's given that these are similar triangles.

In similar triangles, the side lengths are proportional.

We can write the following equation based on this information:

[tex] \frac{11}{3.3} = \frac{7.9}{ef} [/tex]

Cross multiply fractions

11EF = 27.03

Divide both sides by 11

EF = 2.37

You get scores of 72 and 88 on 2 science tests. You have to have an average of at least 85 to not be grounded by your parents. What score do you need to make on your next test to not be grounded?

Answers

Answer:

95

Step-by-step explanation:

72+88+95=255:3= 85

Answer: 95
1. Add both test scores (72 & 88) together. You get 160
2. Then you divide 160 by 2. You get an average of 80.
3. When you add 72, 88, and 95 together you get 255.
4. You then divide 255 by 3
5. You get an average of 85

Express the function F in the form f ∘ g. (Enter your answers as a comma-separated list. Use non-identity functions for f(x) and g(x).) F(x) = x + 2

Answers

Answer:

[tex]F(x) = f \circ g[/tex]

[tex]f(x) = x + 2[/tex] and [tex]g(x) = x[/tex]

Step-by-step explanation:

Given

[tex]F(x) = x + 2[/tex]

Required

Express as

[tex]F(x) = f \circ g(x)[/tex]

In functions:

[tex]f \circ\ g(x) = f(g(x))[/tex]

So, we have:

[tex]f(g(x)) = x + 2[/tex]

g(x) can be set to x and f(x) to x + 2

Hence:

[tex]F(x) = f \circ g[/tex]

When: [tex]f(x) = x + 2[/tex] and [tex]g(x) = x[/tex]

Jack made 9 identical bags using 5 yards of fabric. How much fabric did Jack use for each bag? Solve on paper and check your work on Zearn.

Answers

Answer: 5/9 yards

Step-by-step explanation:

From the question, we are informed that Jack made 9 identical bags using 5 yards of fabric.

To calculate the amount of fabric that Jack use for each bag, we have to divide 5 by 9. Thus will be:

= 5 / 9

Therefore, it means that Jack used 5/9 yards for each bag

Micah invests $5,280 in an account that earns 4.2% interest, compounded monthly.

Part A
Write a function for the amount that will be in the account after t years.

Part B
What is the value of the account after 8 years?

Answers

a) The function is given as follows: [tex]A(t) = 5280\left(1 + \frac{0.042}{12}\right)^{12t}[/tex]

b) The value of the account after 8 years is given as follows: $7,384.

What is compound interest?

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

P is the principal, which is the value of deposit/loan/....r is the interest rate, as a decimal value.n is the number of times that interest is compounded per year, annually n = 1, semi-annually n = 2, quarterly n = 4, monthly n = 12.

The parameter values for this problem are given as follows:

P = 5280, r = 0.042, n = 12.

Hence the equation is given as follows:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]A(t) = 5280\left(1 + \frac{0.042}{12}\right)^{12t}[/tex]

The value of the account after 8 years is obtained as follows:

[tex]A(8) = 5280\left(1 + \frac{0.042}{12}\right)^{12 \times 8}[/tex]

A(8) = $7,384.

Mrs. Beppu's property has four sides. An aerial view of her property is shown below. What term best describes the shape of her property?

Answers

Answer:

rectangle

Step-by-step explanation:

From the picture attached below of the aerial view of Mrs. Beppu's house we can see that it is a rectangle. That is because it has 4 sides with only the parallels being the same size. Meaning that both the width and the length of the house are not the same. This removes the possibility of it being a square. Since all the angles seem to be right angles it also removes the possibility of it being a trapezoid. The best choice would be that it is a rectangle.

Some important pieces of information regarding the cycle are: The nonidealities occur during the adiabatic compression and expansion processes. At the beginning of the compression process, the air is at 95 kPa and 22C. The pressure bounds (i.e. the minimum and maximum pressure) for this non-ideal cycle are the same as they would be under ideal operating conditions. Ideally, the compression ratio for this cycle would be rideal = 10. The specific volume at the end of the isobaric expansion is the same for the real cycle and the idealized cycle. The temperature is measured to be 800 K after the adiabatic compression process. The cutoff ratio for the real cycle is r= 2.5. The adiabatic expansion produces 85% of the work it would produce if it were also reversible. Treat air as having constant specific heats at 300 K during your analysis. a) Sketch an ideal Diesel cycle on P-v and T-s diagrams. You do not need to specify any property values on your diagrams. Using the ideal cycles for reference, sketch the non-ideal Diesel cycle described above on the same axes. Again, you need not specify any property values; just focus on getting the general trends correct. b) Determine the isentropic efficiency of the compression process. c) Determine the thermal efficiency of this cycle. d) Determine the ratio of the thermal efficiency of this cycle compared to its ideal counterpart. That is, determine thermal real/thermal,ideal
