Use the Law of Sines

FE/sin38=18/sin90

FE=18sin38=11.08

DF/sin52=18/sin90

DF=18sin52=14.2

Answer:

FE = 11.08, DF = 14.18

Step-by-step explanation:

Use trigonometric ratios:

sin = opposite / hypotenusecos = adjacent / hypotenuse

Apply to the given triangle

Side FE

FE / DE = sin 38° (or cos 52°, the value is same)FE / 18 = sin 38°FE = 18 sin 38°FE = 11.08

Side DE

DF / DE = sin 52° (or cos 38°, the value is same)DF / 18 = sin 52°DF = 18 sin 52°DF = 14.18

Answer:

Mean: 20

Median: 20

Mode: 5, and 20

Range: 30

Step-by-step explanation:

Mean: Add all the numbers up then divide by the total of numbers there are. 5+30+35+20+5+25+20=140 divided by 7

Median: middle number, list all the numbers from greatest to least and whatever number is in the middle is your answer (5, 5, 20, 20, 25, 30, 35)

Mode: Number that is repeated the most. 5, and 20

Range: The distance from the highest number to the lowest 35-5= 30

Brainliest?

I’m going to do #1 and explain how I do it and I hope it will help!

#1 -

5, 30, 35, 20, 5, 25, 20

Rearrange in order.

5, 5, 20, 20, 25, 30, 35

Mean: Add all the numbers in the set together, then divide by how many numbers there are. So in this case, when you add these up, you get 140. Then you have to divide it by how many numbers, which there are 7 numbers in the set. So... 140 divided by 7 is 20. The mean is 20.

Median: The median is always the middle number in the set. If there are even numbers, you subtract the two numbers in the middle to get a median. But in this case, there is odd, and the middle number there is 20.

Mode: How you find the mode is simply the number that repeats the most or that you see the most. If no number repeats in the set, then you put “No Mode.” So here, there are two numbers that appear twice, so 5 and 20 is the mode.

Range: The range is subtracting the first from the last number. In this case, it would be 35 - 5, and that would be 30, so the range is 30!

Find the equation of the linear function represented by the table below in slope-
intercept form.

Answers

Answer:

f(x) = 5x - 5

Step-by-step explanation:

Let the equation of the linear function is,

f(x) = mx + b

Here, m = Slope of the graph

b = y-intercept

Slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]

From the table attached,

Slope of the line passing through (2, 5) and (6, 25) will be,

m = [tex]\frac{25-5}{6-2}[/tex]

m = 5

Equation of the linear function will be,

f(x) = 5x + b

Since, a point (10, 45) lies on the function,

45 = 5(10) + b

b = 45 - 50

b = -5

Equation of the linear function will be,

f(x) = 5x - 5

what Is the answer to 1/6 + 2/3

Answers

Answer:

5/6

Step-by-step explanation:

When adding fractions, you must ensure the denominator is the same in both fractions.

In this case, the 3 can be multiplied by 2 to equal 6, the other denominator.

When multiplying fractions to create a common denominator, you must multiply the both the numerator and the denominator by the same value, to ensure that the fraction is still equivalent.

2/3 × 2/2 = (2×2)/(3×2) = 4/6

Replace 2/3 with its equivalent 4/6.

Now you will add the numerators together.

1/6 + 4/6 = (1+4)/6 = 5/6

Your final answer is 5/6

Answer:

5/6

Step-by-step explanation:

Tyler needs to complete this table for his consumer science class. He knows that 1 tablespoon contains 3 teaspoons and that 1 cup contains 16 tablespoons.
What are the values of t, x, y, and c ?​

Answers

Answer:

Step-by-step explanation:

This table reflects the proportional relationship amongst number of teaspoons, number of tablespoon, number of cups.

In other words these three measures are proportional.

By taking proportionality ratio of 'number of tablespoons' and 'number of cups' first.

[tex]\frac{12}{48}=\frac{C}{3}[/tex]

C = [tex]\frac{12\times 3}{48}[/tex]

C = 0.75

Similarly, [tex]\frac{y}{2}=\frac{12}{C}[/tex]

[tex]\frac{y}{12}=\frac{2}{0.75}[/tex]

y = [tex]\frac{24}{0.75}[/tex]

y = 32

Now, [tex]\frac{t}{36}=\frac{y}{12}[/tex]

[tex]\frac{t}{36}=\frac{32}{12}[/tex]

t = 96

By the same rule,

[tex]\frac{36}{x}= \frac{12}{48}[/tex]

x = [tex]\frac{48\times 36}{12}[/tex]

x = 144

Therefore, complete table will be,

Number of teaspoons       Number of tablespoons          Number of cups

          96                                            32                                          2

          36                                            12                                        0.75

         144                                            48                                          3

Hope this helps:)

Answer:

EASY PEASY

n = -18

Step-by-step explanation:

Simplifying

n + 7 = -11

Reorder the term:

7 + n = -11

Solving

7 + n = -11

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + n = -11 + -7

Combine like terms: 7 + -7 = 0

0 + n = -11 + -7

n = -11 + -7

Combine like terms: -11 + -7 = -18

n = -18

Simplifying

n = -18
