Answer:
y = 8
x = 8√5
z = 4√5
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (y), x is a projection (16), and y is the other projection (4):
y 4
---- = -----
16 y
Cross multiply:
y² = 16 (4)
y² = 64
√y² = √64
y = 8
To find x and z, use the Pythagorean Theorem:
16² + y² = x²
256 + 8² = x²
256 + 64 = x²
320 = x²
√320 = √x²
√64√5 = √x²
8√5 = x
x = 8√5
4² + y² = z²
16 + 64 = z²
80 = z²
√80 = √z²
√16√5 = √z²
4√5 = z
z = 4√5

Step-by-step explanation:
6^2 + 11^2
36+121 = 157
sqrt157=c
Answer:
a^2 + b^2 = c^2
6^2 + 11^2 =c^2
36 + 121 =c^2
c^2 = 157

Answer:
no solution
Step-by-step explanation:
x²-4 is (x+2)(x-2), which is your least common multiplier
So first, eliminate the denominators by multiplying all terms by (x+2)(x-2)
(x+2)(x-2)/(x-2) + (6x)(x+2)(x-2)/(x+2)(x-2) = 3(x+2)(x-2)/(x+2)
Then simplify
(x+2) + (6x) = 3(x-2)
combine the variables, and expand the right side of the equation
7x + 2 = 3x - 6
Subtract 2 from both sides
7x = 3x - 8
Substract 3x from both sides
4x = -8
Divide both sides by 4
x = -2
Although x = -2, the final answer is undefined.
Because if you plug x = -2 back into the equation, you would get...
for example, 3/(x+2) will become 3/(-2+2), which is 1/0
it is not possible to divide by 0
anything divided by 0 is undefined, therefore this equation has no solution.

You are at Coney Island Amusement Park, and burgers
cost $5 and hot dogs cost $3. You and your friends
spend $45. This is modelled by the equation
5b + 3h= 45.
Is the solution (2, 5) a viable solution?
show your work to the left]
Answer: No, the ordered pair (2,5) is not a viable solution
===========================================================
Explanation:
(2,5) means that b = 2 and h = 5
I'm assuming each ordered pair is of the form (b,h) where b comes first, since b is before h in the alphabet.
So if b = 2 and h = 5, then we can replace each letter with those numbers to get the following:
5b + 3h = 45
5*2 + 3h = 45 ..... b replaced with 2
5*2 + 3*5 = 45 ..... h replaced with 5
10 + 15 = 45
25 = 45
We don't get the same number on both sides, so (b,h) = (2,5) is not a solution.
--------------
Put another way:
If b = 2 and h = 5, this means you bought 2 burgers and 5 hot dogs
1 burger = $5
2 burgers = 2*5 = $10
1 hot dog = $3
5 hot dogs = 5*3 = $15
total amount spent = $10 + $15 = $25
total amount spent = $25
This does not match up with the $45 total spent that we're given. So this is another way to see we don't have a solution.

the x and y intercepts for this equation plz y=−1/4x+2
(_,_)
Answer:
[tex] \boxed{ \boxed{ \sf \: x \: intercept : 8 \atop \sf \: y \: intercept : 2}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:linear equationPEMDASgiven:[tex] \tt y = - \frac{1}{4} x+ 2[/tex]to find:x and y intercepttips and formulas:to find x and y intercept we have to substitute x and y to 0 let's solve:let's substitute x to 0 to find y intercept
y=-¼(0)+2y=2therefore y intercept is 0
let's substitute y to 0 to find x intercept
0=(-¼)x+2(-¼)x=-2x=-2×-4x=8therefore
x intercept is 8and
y intercept is 2also see the graph
explanation of the graph
you can clearly see that the red line crosses x and y axis to (8,0) and (0,2) respectively
therefore
x intercept is 8
and
y intercept is 2

A flagpole and a model flag pole have a scale factor of 1 in.= 4 ft. If the model pole measures 12 inches, how tall is the actual pole?
Answer:
[tex]48\ \text{feet}[/tex]
Step-by-step explanation:
[tex]1\ \text{inch}[/tex] of the model is [tex]4\ \text{feet}[/tex] of the actual pole.
Here, the pole which is present in the model measures [tex]12\ \text{inches}[/tex], so
[tex]12\ \text{inches}[/tex] of the model will be [tex](12\times 4)\ \text{feet}=48\ \text{feet}[/tex]
Hence, the actual pole will be [tex]\boldsymbol{48\ \text{feet}}[/tex] tall.
Bill rented a truck for one day. There was a base fee of $16.99, and there was an additional charge of 92 cents for each mile driven. Bill had to pay $185.35 when he returned the truck. For how many miles did he drive the truck? miles
Answer:
He paid $18 of which $15.95 was
the flat fee.
18.00
- 15.95
---------
$2.05 is the amount paid for mileage.
This is 205 cents for mileage
at 71 cents per mile. Divide
205 by 71 to get the miles driven.
205/71 = 2.9 miles.

What are the factors of -36 that will sum to give you a -5?
Answer:
4, and -9
Step-by-step explanation:
Well, to solve this problem, lets first list all the factors of -36.
-36 = 1*(-36)
-36 = 2 * (-18)
-36 = 3 * (-12)
-36 = 4 * (-9)
-36 = 6 * (-6)
-36 = 12 * (-3)
-36 = 18 * (-2)
-36 = (-36) * 1.
So, we can see that 4 + (-9) = -5.
What is the outlier in the following data set:
15,11,10,8,9,1,8,7,5,4,2,3, and 37?
Step-by-step explanation:
The steps to find an outlier:
1. Put the data in numerical order.
2. Find the median.
3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts.
The median with the smallest value is called Q1. The median for all the values - usually just called the median is also called Q2. The median with the largest value is Q3.
4. Subtract...Q3 - Q1. This value is the InterQuartileRange or IQR. Remember that the range means taking the largest minus the smallest. This is a special range having to do with the quartiles.
5. Multiply...1.5 * IQR
6. Take your answer from #5 and do 2 things with it. A). Subtract it from Q1 and B) Additional to Q3.
7. Look at all your data points. If any are SMALLER than Q1 - 1.5 *IQR, they are outliers. If any are LARGER than Q3 + 1.5 *IQR, they are also outliers.
For your data....the median, Q2 is
(43+38)/2 = 40.5.
Q1 = (30+26)/2 = 28.
Q3 = (54+52)/2 = 53
The IQR is 53 - 28 = 25
1.5 * IQR = 37.5
Q1 - 37.5 = 28 - 37.5 = -9.5. There is no data value less than -9.5.
Q3 + 37.5 = 53 + 37.5 = 90.5. there is no data value greater than 90.5.
My conclusion is that there are no outliers in this data.
I hope this helps!

2.5+3(5-2.1p)=-13.37
Answer:
p=4.9
Step-by-step explanation:
Answer:
4.9
Step-by-step explanation:
[tex]2.5 + 3(5 - 2.1p) = - 13.37[/tex]
1) Open the brackets by multiplying 3 with each term present inside the bracket.
[tex] = > 2.5 + 15 - 6.3p = - 13.37[/tex]
2) Add the constant teems present in left-hand side.
[tex] = > 17.5 - 6.3p = - 13.37[/tex]
3) Take 17.5 to right-hand side by changing its sign from positive to negative.
[tex] = > - 6.3p = - 13.37 - 17.5[/tex]
[tex] = > - 6.3p = - 30.87[/tex]
4) Take -6.3 to right-hand side by dividing -30.87 by --6.3.
[tex] = > p = \frac{ - 30.87}{ - 6.3} = 4.9[/tex]
