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

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.

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

Jenna is at a fair with four friends. They all want to ride the roller coaster, but only three people can fit in a car. How many different groups of three can the five of them make
Answer:
They can make 10 different groups of three.
Step-by-step explanation:
The order in which the people are in the car is not important, so we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many different groups of three can the five of them make?
Combinations of 3 from a set of 5. So
[tex]C_{5,3} = \frac{5!}{3!(5-3)!} = 10[/tex]
They can make 10 different groups of three.
Simplify -6(a +8) can someone help me with that with the steps included
Answer:
−6(a+8)
=(−6)(a+8)
=(−6)(a)+(−6)(8)
=−6a−48
Step-by-step explanation:
multiply -6 x a to get -6a and multiply -6 x 8 to get -48 so -6a-48
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.
Please help me I will offer 20 points
Answer:
9.3 x 8.5 = 79.05
7.6 x 2.4 = 18.24
an easier way to multiply decimals is to take away decimals and add later
example: 9.3x8.5 > 93x85 = 7905 since there are two places behind the decimal add that many to the solution 7905 > 79.05

Which of the following is the product of the rational expressions shown below ? (x + 3)/(x + 2) * (x - 3)/(x - 2)
Answer:
Option D : [tex]\frac{x^2-9}{x^2-4}[/tex] is the correct answer.
Step-by-step explanation:
Given rational expression is:
[tex]\frac{x+3}{x+2}*\frac{x-3}{x-2}[/tex]
In the first step of solving the rational expression, we will multiply the nominators and denominators.
[tex]\frac{(x+3)(x-3)}{(x+2)(x-2)}[/tex]
[tex]\frac{x^2-3x+3x-9}{x^2-2x+2x-4}[/tex]
Now we will solve the alike terms.
[tex]\frac{x^2-9}{x^2-4}[/tex]
The product of rational expression is [tex]\frac{x^2-9}{x^2-4}[/tex]
Hence,
Option D : [tex]\frac{x^2-9}{x^2-4}[/tex] is the correct answer.
Answer:
option D

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
