A. 5.6
B. v32
C. 16
D. 4v2
E. 16v2
F. 1
The length of each leg of the given triangle is 16√2.
What is the triangle?Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
The length of the leg is calculated by using the angle property. Use sin angle to calculate each leg.
First leg,
Sin45 = P / H
1 / √2 = P / 32
P = 32 / √2
P = 16√2
Second leg,
Sin45 = P / H
1 / √2 = P / 32
P = 32 / √2
P = 16√2
Therefore, the length of each leg of the given triangle is 16√2.

What is the equation of the line that passes through the point (4, -4) and has a
slope of ?
Answer:
[tex] y = -\frac{5}{2}x + 6 [/tex]
Step-by-step explanation:
Using a point (4, -4) and the slope of the line that passes through it, m = -⁵/2, we can generate an equation by using the point-slope form equation of a line given as y - b = m(x - a).
Where,
(a, b) = (4, -4)
m = -⁵/2
Plug in the values
y - (-4) = -⁵/2(x - 4)
y + 4 = (-5x + 20)/2
Multiply both sides by 2
2y + 8 = -5x + 20
Subtract both sides by 8
2y = -5x + 20 - 8
2y = -5x + 12
Divide both sides by 2
y = -⁵/2x + 12/2
[tex] y = -\frac{5}{2}x + 6 [/tex] (equation in slope-intercept form)

A farm raises cows and chickens. The farmer has a total of 46 animals. One day he counts the legs of all his animals and realizes he has a total of 156 legs. How many cows does the farmer have?
Thanks in advance, I really appreciate it :)
Answer:
Step-by-step explanation:
lets note a= chickens
b=cows
a+b=46
also = chickens has 2 legs, cow=4 legs
2a+4b=156..........we divide this equation by 2 so we can work with smaller numbers
a+2b=78 or we cam write a=78-2b
lets replace in the first equation a+b=46
78-2b+b=46
-b=46-78
-b=-32 multiply by -1
b=32
so we have 32 cows with 128 legs
a+32=46
a=14 chickens with 28 legs

Grandma’s Guide to Cooking Measurements
Dried Seasonings
1 pinch = 2 smidgens
1 dash = 2 pinches
1 sprinkle = 3 pinches
1 teaspoon = 8 dashes
Based on Grandma's guide to cooking, how many pinches are in one teaspoon?
Using proportions, it is found that there are 16 pinches in one teaspoon.
This question is solved by proportions, using a rule of three.One dash has 2 pinches. One teaspoon is the same as 8 dashes. How many pinches are there in 8 dashes?Hence, the rule of three is:
1 dash - 2 pinches
8 dashes - x pinches
Applying cross multiplication:
[tex]x = 2(8) = 16[/tex]
There are 16 pinches in one teaspoon.

George has a coin collection. 16% of the coins are quarters from the
1990s. If he has 32 quarters from the 1990s, how many total coins does he
have?
Answer:
200
Step-by-step explanation:
Given that :
16% of coins are quarters from 1990
Number of quarters from 1990 = 32
Since 16% = 32 quarters
The number of the total coins can be obtained thus :
Let the total number of coins = x
16% = 32
100% = x
Cross multiply :
0.16x = 32 * 1
0.16x = 32
x = 32 / 0.16
x = 200
Hence, total number of coins in the collection = 200

Write a linear equation that is parallel to 5x+2y=-8 and passes through the point (8,-9)
Answer:
y= -5/2x+11
Step-by-step explanation:
You want to first reorder the equation into slope intercept form
First subtract 5x from both sides
5x-5x+2y = -8-5x
It should look like:
2y = -5x - 8
Then isolate your y variable
Since the y is multiplied with 2 divide by 2 to isolate and remember to divide the other side as well
It should look like:
2y/2 = -5/2x -8/2
This will result in y = -5/2x - 4
Now since the line is parallel the slope will be the same but to pass through a different point the y intercept will have to change.
Re make your equation and you have:
y = -5/2x + b
Now plug in your (x,y) value for the x and y in the slope intercept form.
-9 = -5/2(8) +b
Now solve for b:
-9 = -40/2 +b
-9 = -20 +b
Isolate your y intercept by adding 20 to both sides
-9 + 20 = -20 + 20 +b
which results with b = 11
Now you have all components to your final slope intercept form giving you the answer
y = -5/2x + 11

The Amazon River, one of the
longest rivers in the world, is about 6,400 kilometers long. If 1 mile equals 1.6 kilometers, what is the length of the Amazon River in miles?
Answer:
4000 miles.
Step-by-step explanation:
Divide 6400 by 1.6 to get 4000
Answer:
If we know each miles are 1.6 km, we can do a rule of three to get the length of the river:
1 1.6
X 6400
Now, we know that = 4000 miles
You can also just divide 6400/ 1.6 as each 1.6 kilometers are one mile
You are a personnel director and are interested in predicting the Number of Shares of Company Stock (Y) using the Number of Years Employed with the Company (X). You randomly selected 8 employees and found that the average number of shares is 525 and the average number of years employed is 22.5. If the slope (b1) is 20.0, what is the least squares estimate of the intercept (b0)?
a. 25.0
b. 75.0
c. 40.0
d. 80.5
e. None of these are correct
Answer:
b. 75.0
Step-by-step explanation:
Calculation for the least squares estimate of the intercept (b0)
Using this formula
Intercept (b0) least squares estimate=[Shares average number-(Slope (b1)*Average number of years employed)]
Let plug in the formula
Intercept (b0) least squares estimate=[525-(20.0*22.5)]
Intercept (b0) least squares estimate=525-450
Intercept (b0) least squares estimate=75.0
Therefore the least squares estimate of the intercept (b0) will be 75.0

How many distinct rearrangements of the letters in "sleepless" are there?
Answer:
[tex]N = 5040[/tex]
Step-by-step explanation:
Required
Arrange the letters of "sleepless"
First, we count the number (n) of characters
[tex]n = 9[/tex]
First, we count the number (n) of repeated characters
[tex]s = 3[/tex]
[tex]e = 3[/tex]
[tex]l = 2[/tex]
The arrangement (N) is then calculated as follows;
[tex]N = \frac{n!}{s!e!l!}[/tex]
This gives:
[tex]N = \frac{9!}{3!3!2!}[/tex]
[tex]N = \frac{9*8*7*6*5*4*3*2*1}{3*2*1*3*2*1*2*1}[/tex]
[tex]N = \frac{362880}{72}[/tex]
[tex]N = 5040[/tex]
Hence, there are 5040 distinct arrangements
At a coffee shop, the first 100 customers' orders were as follows. What is the probability that a customer ordered a hot drink given that he or she ordered a large? PLEASE HELP
Answer:
22%

22%
The probability that a customer ordering a hot drink given that he or she ordered a large will be 22%.
What is Probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
From the table, we can see that the hot and large coffee customers are 22 in number.
The total number of customers is 100.
Probability = 22 / 100 = 22%
Therefore the probability that a customer ordering a hot drink given that he or she ordered a large will be 22%.
