Answer 1

Answer:

Step-by-step explanation:

Use the Law of Sines

FE/sin38=18/sin90

FE=18sin38=11.08

DF/sin52=18/sin90

DF=18sin52=14.2

Answer 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

Give the area of land 25m wide and 50m long

Answers

The area of the land is 1250 square meters.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length by the width.

So the formula for finding the area of the rectangle is

Area = Length * Width

In this case, the land is 25 meters wide and 50 meters long, so the area is:

Area = length × width

Area = 50 m × 25 m

Area = 1250 m²

Hence, the area of the land is 1250 square meters.

One year, the population of a city was 127,000. Several years later it was 129,540. Find the percent increase.

Answers

Answer:

Step-by-step explanation:

Answer: 2%

Step-by-step explanation: Method 1

Express the ending population as a percentage of the starting population:

127000 /129540= 1.02

1.02×100= 102%

Subtract the starting 100% to get the percent increase:

102%−100%= 2%

Collectively, what are the interest costs and other fees for using a credit card called? A. balance B. credit line C. finance charge Reset Next

Answers

The correct answer is C. Finance charge

Explanation:

A credit card is a service offered by financial entities such as banks that allows customers to buy goods and pay them later. This implies the customer does not immediately for goods but pays for these after a specific time. The use of this benefit implies related costs such as fees for the use of the credit card, and interest costs (money charged for borrowing the money from the bank), which are known as finance charge or the money charged for the benefit of using credit. According to this, the correct answer is C.

Change 3 5/8 into an improper fraction.

Answers

Answer:

The improper fraction 29/8 is equal to the mixed number 3 5/8.

Step-by-step explanation:

The fractions is solved and the improper fraction is A = 29/8

Given data ,

To change 3 5/8 into an improper fraction, we need to combine the whole number and the fraction part.

The fraction part, 5/8, can be expressed as an improper fraction by multiplying the whole number, 3, by the denominator of the fraction, 8, and then adding the numerator, 5. This gives us:

3 * 8 + 5 = 24 + 5 = 29

The denominator remains the same, so the improper fraction is:

A = 29/8

Therefore , the value of A = 29/8

Hence , 3 5/8 can be expressed as the improper fraction 29/8

b. What percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon (to 1 decimal)?

c. What percentage of regular grade gasoline sells for less than $3.55 per gallon (to 1 decimal)?

%

Answers

The percentage of regular grade gasoline sells for between $3.35 and $3.55 per gallon is 64%

The percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon is 81.5%

The percentage of regular grade gasoline sells for less than $3.55 per gallon is 84%

Given :

Mean retail price is $3.45

Standard deviation is 0.10

Empirical rule states that 99.7% of data is observed in normal distribution that lies within 3 standard deviations.

68% of data lies under 1 standard deviation

95% lies under 2 standard deviations

99.7% lies under 3 standard deviations

there are 3 standard deviations on the left and right of mean . The graph is attached below

Mean is 3.45. standard deviation is 0.1

3.45+0.1=3.55

3.45-0.1=3.35

So 3.35 and 3.55 lies under first standard deviation

The percentage between $3.35 and $3.55 is 68%

3.45 +0.1+0.1=3.65

3.35 lies on 1 standard deviation on left and 2 deviations on the right of mean

So , 34+34+13.5=81.5%

The percentage between $3.35 and $3.65 is 81.5%

For gasoline sells for less than 3.55 , there are 3 standard deviation on the left of mean and 1 standard deviation on the right

0.15+2.35+13.5+34+34=84%

(I will mark brainliest) Use this equation to solve for the missing variable:

y = 8x + 12

If x = -6, y = _____

If y = 13, x = _____

Answers

Answer: x would be 1/8 and y would be -36

Step-by-step explanation:

To find put y you would plug in -6 for x. So it would be y=8(-6)+12. Then you multiply the 8 and -6 to get -48, y=-48+12. Then subtract 48 from 12 and that is -36 so y=-36. To solve for x you would plug in the y or 13 into the equation. So, 13=8x+12. Then you would have to solve. 12 minus 13 is 1 and the you are left with 1=8x then you divide 1/8 and 8x/8 and you get x=1/8. Hope this helped!

John was adding Rational Numbers. He showed his work below. What was John's error?

Explain to John how to solve it correctly.

Adding Rational Numbers Error.

Answers

Answer:

-5 3/5

Step-by-step explanation:

John's error was in adding the whole number and fractional portions separately, the fractions must be converted to improper fractions with common denominators to be added or subtracted properly so

(-7 4/5) + (2 1/5), convert to improper fractions

-39/5 + 11/5, both fractions have common denominator so we can continue

-39 + 11 = -28, so -39/5 + 11/5 = -28/5, convert back to proper fractions

-28/5 = (-25/5) + (-3/5) = -5 3/5
