If the lengths of the legs of a triangle are 27 cm and 36 cm, what is the length of the hypotenuse, c?​

Answers

use the pythagorean theorem!

a^2 + b^2 = c^2

plug in the values:

27^2 + 36^2 = c^2

simplify to get your answer:

729 + 36^2 = c^2

729 + 1296 = c^2

2025 = c^2

√2025 = c

45 = c

the length of the hypotenuse is 45cm

hope this helps!

Step-by-step explanation:

Andros has an oil fired heating system. In 30 days period he used a full tank of oil at a constant rate per day . At a different time of the year the amount of oil andros uses per day is 1/3 of the rate used in 30 days period . How many days should a full tank of oil last at this new rate

Answers

Answer:

90 days

Step-by-step explanation:

Let the rate per day for the 30 days period be x

Given that the rate drops to 1/3 of the rate used in 30 days period, it means that the new rate

= 1/3 x

If at a rate of x, the full tank runs for 30 days

at a rate of 1/3 x, the full tank would run for

= x/ (1/3 x) * 30 days

= 3 * 30 days

= 90 days

At the new rate, the full tank of oil will last for 90 days

Answers

Answer:

9 Miles to be specific 8.95

Step-by-step explanation:

3 miles = 4.83 km

4.83 km = 4830 m

60 seconds X 45 =2700 Seconds

4830 divided by 2700 = 1.78 m/s

you want to know the distance so its speed X time

135 minutes X 60 seconds = 8100 secs

1.78 m/s X 8100 =14418 meters

14418 = 14.418 km

14.418 km = 9 miles

I need help ASAP! And work needs to be shown!

Answers

Answer:

32 x p/100 = 40

(Solve for P)

Multiply by 100 on both sides

32x = 4,000

Divide by 32 to get:

X = 125%

(reason why you multiply by 100 is because opposite of division is multiplication and we multiply the number "100" because we always multiply the denominator to both sides when having a fraction so you can solve for p or whatever. And that means p/100 x 100 it means p because since p is not a known value we consider 1/100 x 100 = 1, a variable by itself means 1 so you could just put p by itself next to the number its multiplied by which is 32 so it would be 32p because your multiplying both and the opposite of that would be dividing by 32 on both sides because you are getting rid of the 32 so therefore you will be left with: X = 125)

Given that ABCD~JKLM
find the ratio of the perimeter of ABCD to JKLM

Answers

Answer:

The ratio of the perimeter of ABCD to JKLM is;

b. 3/5

Step-by-step explanation:

Given that ABCD ~ JKLM, where;

DC and ML are corresponding sides

AD and JM are corresponding sides

AB and JK are corresponding sides

Therefore;

DC/ML = AD/JM = AB/JK

Plugging in the values of the variables gives;

9/15 = z/10 = x/12

∴ z = 10×9/15 = 6

x = 12×9/15 = 7.2

9/15 = 6/y

y = 6 ×15/9 = 10

The perimeter of the quadrilateral ABCD = AB + BC + DC + AD

∴ The perimeter of the quadrilateral ABCD = 6 + 6 + 9 + 7.2 = 28.2

The perimeter of the quadrilateral JKLM = JK + JM + ML + LK

∴ The perimeter of the quadrilateral JKLM = 12 + 10 + 15 + 10 = 47

The ratio of the perimeter of ABCD to JKLM = 28.2/47 =0.6 = 3/5.

Investment firm claims that the mean increase in price per share companies invest in is $1.95 per share every year and national sample of 100 company shows that the mean increase in price per share is $1.82 per year the standard deviation of share price is nationally is $.30 what is the margin of error

Answers

Answer:

The Margin of Error in percentage is 5.88%

Step-by-step explanation:

The values of the factors in the question are;

The mean increase in price per share,  = $1.95

The number of companies in the sample, n = 100

The mean increase in price per share, [tex]\overline x[/tex] = $1.82

The standard deviation of the population, σ = $0.30

The margin of error, MOE, is given by the following formula;

[tex]Margin \ of \ Error= z \times \dfrac{\sigma}{\sqrt{n} }[/tex]

Where;

z = z-score, critical value = 1.96 at 95%

σ = The standard deviation of the population = $0.30

n = The sample size = 100

Therefore, we have;

[tex]Margin \ of \ Error= 1.96 \times \dfrac{0.3}{\sqrt{100} } = 0.0588[/tex]

The Margin of Error in percentage = 0.0588 × 100 = 58.8%

The Margin of Error in percentage = 5.88%

Answers

Answer: C = 9

Step-by-step explanation:

Answer:

c=10.6

Step-by-step explanation:

In this we need to find c and we know that this is a right triangle

Therefore, I can use the Pythagorean Theorem which is a^2 + b^2 = c^2.

using this we then plug in a=8 and b=7 while c is the hypotenuse.

Now the equation is now 8^2 + 7^2 = c^2. We then solve for c.

8^2 + 7^2 = c^2

64 + 49 = c^2

113 = c^2

√113 = c

c = 10.630145...
