Solve for AB. Round your answer to the nearest tenth if necessary.
Answer:
AB = 55.25
Step-by-step explanation:
Set up an equation where the length of AB is equal to AC minus BC. This will allow us to solve for x, and then the length of AB.
AB = AC - BC
5x + 9 = 87 - (3x + 4)
5x + 9 = 87 - 3x - 4
5x + 9 = 83 - 3x
8x + 9 = 83
8x = 74
x = 9.25
Now plug 9.25 in for x in the equation for AB
AB = 5x + 9
AB = 5(9.25) + 9
AB = 46.25 + 9
AB = 55.25
Factor completely by grouping.
x^3 + 7x^2 + 9x + 63
Answer:
(x+7)(x2+9)
Step-by-step explanation:
Answer: x^3+ 261x +63

How would you solve this(what is the equation of the line that passes through the point (3,4) and has a slope of -2/3?)//delta math//
Answer:
[tex]y = -\frac{2}{3}x + 6[/tex]
Step-by-step explanation:
y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.
4 = [tex]-\frac{2}{3}[/tex](3) + b
-2/3 times 3 is -2 so you can fill that in place.
4 = -2 + b
+2 +2
6 = b
So the y-intercept is 6 now we can complete the equation.
[tex]y = -\frac{2}{3}x + 6[/tex]
Hope that helps and have a great day!

C: 3/2
D: 3/1
Answer:
A: 1/3
Step-by-step explanation:
The ratio is 1 part water to 3 parts juice.
The amount of water in the ratio works out to be 1/3 of the amount of juice.
For 1 part juice, use 1/3 of that amount of water, so use 1/3 part water.
Answer: A 1/3
What’s a better buy? 80 marbles for $4.99 or 90 marbles for $5.99?
80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99
What is comparison in mathematics?
Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given are 80 marbles for $4.99 and 90 marbles for $5.99.
Using Unitary method -
80 marbles cost → $4.99
1 marble will cost → (4.99/80) = $0.062
90 marbles cost → $5.99
1 marble will cost → (5.99/90) = $0.066
Clearly $0.062 < $0.066
So, 80 marbles for $4.99 is a better buy.
Therefore, 80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99

THIS IS STATISTICS** Are physically fit people less likely to die of cancer? An article in the May 2002 issue of "Medicine and Science in Sports and Exercise" reported results of a study that followed 25,892 men aged 30 to 87 for 10 years. The most physically fit men had a 55% lower risk of death from cancer than the least fit group. What is the population of interest and the sample in this scenario? Write your response using complete sentences. plz help
Answer:
In this case the population of interest is the set of all men aged 30 to 87.
In this case the sample is the set of 25,892 men aged 30 to 87.
Step-by-step explanation:
A population is the set of all the data that can be collected and from which a smaller set of data is drawn for further examination. A population may denote to a group of individuals, articles, trials or measurements. A population can thus be called as a collection of information regarding subjects combined together by a common characteristic.
In this case the population of interest is the set of all men aged 30 to 87.
A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.
In this case the sample is the set of 25,892 men aged 30 to 87.

What is butterfly method?When using the butterfly method approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa.
What is proportion?An equation known as proportion shows that the two ratios presented are equal to one another. In other terms, the proportion declares that the two ratios or fractions are equal. In terms of proportion, two sets of supplied numbers are said to be directly proportional if they increase or decrease in the same ratio.
The given proportion is:
[tex]\frac{\frac{1}{2} }{4} = \frac{x}{28}[/tex]
Using the method of cross-product or butterfly method:
[tex]\frac{\frac{1}{2} (28) }{4}=x \\\\\frac{14}{4}=x\\ \\x=3.5[/tex]
The value of x is 3.5. Converting this value into mixed fraction:
3.5 = 3 1/2
Hence, the value of x in the proportion below is option 1 3 1/2.
