find the side of a right triangle
The 2 sides of the right triangle is 25 and 24.
Any multiple of a Pythagorean triple is also considered a Pythagorean triple. Multiplying 3, 4, 5 by 2 gives 6, 8, 10, which is another triple. To see if a set of numbers makes a Pythagorean triple, plug them into the Pythagorean Theorem.
3,4,5 5,12,13 7,24,25 8,15,17 9,12,15
Final Result: 25,24

In a certain triangle two sides have lengths 5 and 13. The angle between them is 49
degrees. What is the area of the triangle?
Answer:
Area = 24.54
Step-by-step explanation:
two sides have lengths 5 and 13.
Let the two sides be;
a = 5
b = 13
The angle between them is 49
C = 49°
Let the third side be c
Thus, using cosine rule, we can find the side c.
c² = a² + b² - 2ac•Cos C
Plugging in the relevant values, we have;
c² = 5² + 13² - 2(5 × 13)Cos 49
c² = 25 + 169 - 130(0.6561)
c² = 108.707
c = √108.707
c = 10.43
Since we now have 3 sides, from herons formula, we can find the area;
Area = √[p(p − a)(p − b)(p − c)]
Where p is half of the perimeter = (a + b + c)/2 = (5 + 13 + 10.43)/2 = 14.215
Thus;
Area = √(14.215(14.215 - 5)(14.215 - 13)(14.215 - 10.43))
Area = √602.4
Area ≈ 24.54
Light bulbs are normally distributed with an average lifetime of 1000 hours and a standard deviation of 250 hours. The probability that a light bulb picked at random will last between 1400 and 1500 hours is about:
Answer:
The probability that a light bulb picked at random will last between 1400 and 1500
P(14 00≤X≤1500) = 0.032
Step-by-step explanation:
Explanation:-
Given that mean of the Population = 1000
Given that the standard deviation of the Population = 250 hours
Let 'X' be the random variable in a normal distribution
Let X = 1400
[tex]Z = \frac{X-mean}{S.D} = \frac{1400-1000}{250} = 1.6[/tex]
Let X = 1500
[tex]Z = \frac{X-mean}{S.D} = \frac{1500-1000}{250} = 2[/tex]
The probability that a light bulb picked at random will last between 1400 and 1500
P(x₁≤ X ≤x₂) = P(Z₁≤ Z ≤z₂)
= A( Z₂ ) -A(Z₁)
P(1400≤X≤1500) = P(1.6≤ Z ≤2)
= A(2 ) -A(1.6)
= 0.4772-0.4452
= 0.032
Final answer:-
The probability that a light bulb picked at random will last between 1400 and 1500
P(14 00≤X≤1500) = 0.032

an honor class is something that helps with your collage and could raise you up a grade but my teacher goes ahead and gives me a D she must be missing brain cells right she has to be because that is ridiculous
Answer:
when the signed you up for the honor class they probably expected you to know more
Answer: knowing what an honors course is, she probably thought you were good at the subject. Just because you got one bad grade on an assignment, doesn't mean that you can't be in an honors course. (That... or she really is missing a brain cell or 2)

In Melanie's Styling Salon, the time to complete a simple haircut is normally distributed with a mean of 25 minutes and a standard deviation of 4 minutes. The slowest quarter of customers will require longer than how many minutes (to the nearest tenth) for a simple haircut?
Answer:
Longer than 27.7 minutes.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 25, \sigma = 4[/tex]
The slowest quarter of customers will require longer than how many minutes (to the nearest tenth) for a simple haircut?
Longer than the 100 - 25 = 75th percentile of times, which is X when Z has a pvalue of 0.75. So X when Z = 0.675. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.675 = \frac{X - 25}{4}[/tex]
[tex]X - 25 = 4*0.675[/tex]
[tex]X = 27.7[/tex]
So
Longer than 27.7 minutes.

SIMPLIFY IT PHOTO IS UP I WILL MARK IT BRAINLIEST
Step-by-step explanation:
Notice that
9y² - 4xy + 4x²/9 = (3y - 2x/3)².
Therefore (9y² - 4xy + 4x²/9) / (3y - 2x/3)
= (3y - 2x/3).
Answer:
(9y²-4xy+4x²/9)/(3y-2x/3)
={(3y)²-2(3y)(2x/3)+(2x/3)²}/(3y-2x/3)
=(3y-2x/3)²/(3y-2x/3)
=(3y-2x/3)
(3y-2x/3) is the right answer.Combine the following like terms 8y - y =

to advertise o radio,the radio station charges 32naira for the first 10 words and 2naira per word for every additional word.how much will it cost to place an advertisement of 68 words on radio?
Answer:
Cost for 68 words = 148 naira
Step-by-step explanation:
Given that:
Cost of first ten words = 32 naira
Cost of additional words = 2 naira per word
Let,
x be the number of additional words.
y be the total cost
y = 2x + 32
We have to find the cost for 68 words.
The cost of first 10 words will be 32 naira.
Additional words = 68 - 10 = 58 words
Putting x = 58 in the equation
y = 2(58) + 32
y = 116 + 32
y = 148
Hence,
Cost for 68 words = 148 naira
Angle AOE has what measurement according to the protractor?
Answer:
140
Step-by-step explanation:
PENN
Hence angle AOE has a measure of 120 Degrees.
What is an Angle?An angle is a combination of two rays (half-lines) with a common endpoint.
How To Solve:When an angle is formed or drawn or opened clockwise , then we measure it using the upper scale of the protractor , and if the angle or its arc goes anticlockwise , we measure it using the bottom scale of the protractor.
According to the figure , the angle has been opened anticlockwise.
(Observe carefully , AOB , then AOC , AOD and so on. Suppose that O is the center of a clock and OA is the needle which is moving anticlockwise from position OA, OB, OC and so on).
So we will use the bottom or lower scale of the protractor. Line Segment OE of angle AOE is bisecting the Lower scale of the protractor at 120 degrees.
Hence angle AOE has a measure of 120 Degrees.

Give 50 mg/kg to a child weighing 56 lbs. The drug is in oral suspension of 100 mg/ml. How many mL would the nurse administer per dose to the child?
Answer:
About 13 ml
Step-by-step explanation:
The child weighs 56 lbs. We need to first convert the weight of the child from lbs to kg so that we can know the amount of drug in mg is needed to be given to the child.
1 lb = 0.4536 kg
[tex]56\ lbs=56\ lbs*\frac{0.4536\ kg}{1\ lb} =25.4\ kg\\\\[/tex]
Therefore the amount of mg needed to be administered to the child = 50 mg/kg * 25.4 kg = 1270 mg
Since the oral suspension is in 100 mg per ml, hence:
Amount per dose = 1270 mg / (100 mg/ml) = 12.7 ml ≅ 13 ml
The child should be given 13 ml for each dose.
