Find the missing side of each right triangle. Side c is the hypotenuse. Sides a and b are the legs. Leave your answers in simple

vredina [299]

Answer:

Side b = 10.2 m (1 d.p.)

Step-by-step explanation:

11² = 121

15² = 225

225 - 121 = 104

√104 = 10.2 (1 d.p.)

Side b = 10.2m

(Full answer = 10.198039)

11² + 10.2² = 15²

Please help with 11,12,13

Problem 11

<h3>Answer: h = 2A/b</h3>

------------------

Explanation:

We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b

A = (1/2)*b*h

2A = b*h

b*h = 2A

h = 2A/b

Problem 12

<h3>Answers:</h3>

Equation: (n+2)/5 = 14
Solution to that equation: n = 68

------------------

Explanation:

The number n is increased by 2 to get n+2

Then we divide by 5 to get (n+2)/5

This is set equal to 14 to get the equation (n+2)/5 = 14

Solving the equation would look like this

(n+2)/5 = 14

n+2 = 5*14 .... multiply both sides by 5

n+2 = 70

n = 70-2 .... subtract 2 from both sides

n = 68

================================================

Problem 13

<h3>Answer: Not a solution</h3>

------------------

Explanation:

We'll replace every copy of x with -3 and simplify

-2x + 5 > 13

-2*(-3) + 5 > 13

6 + 5 > 13

11 > 13

The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.

Therefore, x = -3 is not a solution.

Gabe is planning on riding the roller coaster 25 times. If he has already ridden 36% of his 25 times, how many times has Gabe al

AVprozaik [17]

If you do 25 x X = 100
It would be x = 4
So we would divide 36% by 4 to get how many times he rode, which is 9
So he already has ridden 9 times.

6.3 The daily amount of coffee, in liters, dispensed by a machine located in an airport lobby is a random variable X having a co

dexar [7]

Answer:

a) 60% probability that on a given day the amount of coffee dispensed by this machine will be at most 8.8 liters.

b) 70% probability that on a given day the amount of coffee dispensed by this machine will be more than 7.4 liters but less than 9.5 liters

c) 50% probability that on a given day the amount of coffee dispensed by this machine will be at least 8.5 liters

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

The probability of X being higher than x is:

$P(X > x) = 1 - \frac{x - a}{b-a}$

The probability of X being between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

For this problem, we have that:

$a = 7, b = 10$

(a) at most 8.8 liters;

$P(X \leq 8.8) = \frac{8.8 - 7}{10 - 7} = 0.6$

60% probability that on a given day the amount of coffee dispensed by this machine will be at most 8.8 liters.

(b) more than 7.4 liters but less than 9.5 liters;

$P(7.4 \leq X \leq 9.5) = \frac{9.5 - 7.4}{10 - 7} = 0.7$

70% probability that on a given day the amount of coffee dispensed by this machine will be more than 7.4 liters but less than 9.5 liters

(c) at least 8.5 liters.

$P(X > 8.5) = 1 - \frac{8.5 - 7}{10 - 7} = 0.5$

50% probability that on a given day the amount of coffee dispensed by this machine will be at least 8.5 liters

Salma paid 14.75 for a 2.12 pound bag of shrimp at one store. The following week, she paid 24.99 for a 3.77 pound bag at another

ladessa [460]

To find the unit price of each bag, divide each cost by the weight to find the cost of shrimp per pound.

For the 2.12 pound bag: 14.75 / 2.12 = $6.96 (rounded to the nearest cent)

For the 3.77 pound bag: 24.99 / 3.77 = $6.63 (rounded to the nearest cent)

You can tell that buying the 3.77 pound bag is better based on the unit price because of 6.63 < 6.96.
