A survey showed that out of 600 surgery patients at ABC Medical Center, 8% of them had eye surgery. Find the number of patients that had eye surgery.
Answer:
48
Step-by-step explanation:
.08x600=48
Answer:
Step-by-step explanation:
total patients = 600
% of patients had eye surgery = 8%
Number of patients that had eye surgery ?= x
% of pt that had eye surgery = no. of pt that had surgery/ total number of pt
8/100= x/600
x=(8x600) /100
x= 4800/100
x= 48
Number of patients that had eye surgery were 48

Answer:
√29
Step-by-step explanation:
This is due to A^2+b^2=c^2. you know that side a and b are 2 and 5, so it beocmes 25+4/=c^2, which means that 29=c^2, and you root it to get rid of the power of 2, so you obtain c=√29

360 - 330 = 30 (360 degrees is a whole circle)
a 30 60 90 triangle is made, then use the law for 30 60 90 triangles:
if the shortest leg is x, the other leg is x*rt3 and the hypotenuse is 2x.
Answer:

Step-by-step explanation:
cos 330 = cos (360-330)
= cos 30
= √3 /2
The shorter leg of a right triangle is 5 meters. The hypotenuse is 1 meter longer than the longer leg. Find the
length of the longer leg.
The other leg is
meters.
Answers:
longer leg = 12 meters
hypotenuse = 13 meters
==========================================================
Explanation:
Let's say the triangle has sides a,b,c such that a < b < c
a = 5 = short legb = unknown long legc = b+1 = hypotenuseUse the pythagorean theorem to solve for b
[tex]a^2 + b^2 = c^2\\\\5^2 + b^2 = (b+1)^2\\\\25 + b^2 = b^2+2b+1\\\\25 + b^2-b^2-2b-1 = 0\\\\-2b+24 = 0\\\\-2b = -24\\\\b = -24/(-2)\\\\b = 12[/tex]
The longer leg is 12 meters in length.
c = b+1 = 12+1 = 13
The hypotenuse is 13 meters long.
We have a 5-12-13 right triangle.

In , Americans spent a record-high billion on Halloween-related purchases (the balance website). Sample data showing the amount, in dollars, adults spent on a Halloween costume are as follows. 12 67 25 62 33 38 34 47 53 16 11 97 46 32 62 27 a. What is the estimate of the population mean amount adults spend on a Halloween costume (to decimals)
Answer:
41.375
Step-by-step explanation:
Given the sample data :
The estimate of the population mean from the sample data is given as :
Mean = ΣX / n
Mean = (12+67+25+62+33+38+34+47+53+16+11+97+46+32+62+27) / 16
Mean = 662 / 16
Mean = 41.375

What number should be added to -3/2 to get -5/8
Answer: 7 / 8 should be added
Step-by-step explanation:
Let x be the number that should be added
Write the equation
-3/2 + x = -5/8
Add -3/2 on both sides
-3/2 + x + 3/2 = -5/8 + 3/2
x = -5/8 + 3/2
Change the denominator of 3/2 to 8 in order to do addition
x = -5/8 + 12 / 8
x = 7 / 8
Hope this helps!! :)

State and prove the converse of the pythagorean theorem using a two-column proof
Answer:
Step-by-step explanation:
I'm from the UK and I'm not familiar with a two column proof, but the following proves the converse.
Draw 2 right angled triangles with the 2 legs = a and b in each case and the longest side = c in one triangle and f in the other.
By Pythagoras a^2 + b^2 = c^2 (Given)
Also in the other triangle a^2 + b^2 = f^2, if it is right-angled.
Therefore a^2 = f^2 and a = f.
So the 2 triangles are congruent by SSS.
So m < C in one triangle = m < F ( the angles opposite the hypotenuse)
Therefore the second triangle is right angled .
This completes the proof.
Verify that the indicated function y = ϕ(x) is an explicit solution of the given first-order differential equation. (y − x)y' = y − x + 18; y = x + 6 √(x + 4)
When y = x + 6√(x + 4) y'=_________
Thus in terms of x, (y-x)y'=________
y-x+18=________
If y = x + 6√(x + 4), then
y' = 1 + 3/√(x + 4)
Substituting y and y' into the DE gives
(y - x) y' = (x + 6√(x + 4) - x) (1 + 3/√(x + 4))
… = 6√(x + 4) (1 + 3/√(x + 4))
… = 6√(x + 4) + 18
on the left side, while on the right you get
y - x + 18 = x + 6√(x + 4) - x + 18
… = 6√(x + 4) + 18
so both sides match and the given function is indeed a solution to the DE.
What is the third step in sketching the graph of a rational function
Answer:
use test numbers to find where the function is a positive and where it is negative. sketch the function's graph, plotting additional points as guides as negative. choose test numbers to t the left and right of each of these places, and find the value of the function at each test number.
metal is made using copper, zinc and lead in thr ratio 13:6:1 . if the mass of the zinc is 90kg, calculate the mass of the lead
============================================
Explanation:
Let x be the mass of the lead, and this mass is in kg.
The ratio 13:6:1 can be scaled up to 13x:6x:1x after multiplying all parts by x.
The portion in the middle (6x) represents how much zinc we have, while the last part (1x or simply x) is the amount of lead.
----------------
We're told that we have 90 kg of zinc. Set this equal to 6x and solve for x
6x = 90
6x/6 = 90/6 ..... dividing both sides by 6
x = 15
So we have 15 kg of lead
Side note: we also have 13x = 13*15 = 195 kg of copper.
If $500 were deposited into an account paying 5% interest, compound monthly, how much would be in the account in 4 years?
Please show me proper work and a good explanation on how you got said answer.
Answer:
610.48
Step-by-step explanation:
The formula for compound interest is
A = P(1+r/n) ^nt where
A is the amount in the account
P is the principle
r is the interest rate
n is the number of times the interest is compounded per year
t is the time in years
A = 500(1+.05/12) ^12*4
A = 500(1+.0041666666) ^48
A = 500(1.0041666666) ^48
A = 500*1.220895355
A =610.4476775
Rounding to the nearest cent
A = 610.48
What is the volume of a cone with a radius of 4 inches and height of 11?
Answer:
184.22
Step-by-step explanation:
solve 3 1/5 = y - 12/25
3 1/5 = y - 12/25
31/5+y = -12/25
31+y = -12/25×5
31+y = -12/5
y = -12/5-31
y = -143/5
y = -28.6

What is the value of b? -11b + 7 =40 (also there is another question in the bottom of the picture. If you can answer it please do)
Problem 1
The idea here is to follow PEMDAS in reverse to undo what is happening to the variable b, so we can isolate it.
-11b + 7 = 40
-11b = 40-7
-11b = 33
b = 33/(-11)
b = -3
To check this value, plug it back into the original equation. You should get 40 on each side to help confirm the answer.
Answer: b = -3=====================================================
Problem 2
There are two ways we can solve. One method is to use the hint your teacher gave you. So we'll distribute first and then follow the same idea as problem 1
9(p-4) = -18
9p-36 = -18
9p = -18+36
9p = 18
p = 18/9
p = 2
Another method you can use is to follow these steps
9(p-4) = -18
p-4 = -18/9
p-4 = -2
p = -2+4
p = 2
Either way, we get the same result. To check the answer, replace every p with 2 in the original equation. You should get -18 on the left side after simplifying.
Answer: p = 2Solve the above quadratic equation

The diagram shows a wooden prism of height 5cm.
The cross section of the prism is a sector of a circle with sector angle 25º.
The radius of the sector is 15 cm.
Calculate the total surface area of the prism.
Answer:
280.8997
Step-by-step explanation:
cross section = 2*15*5+2*(25/360)*15*15*pi+5*(25/360)*2*pi*15
= 280.8997
Total surface area of prism is 280.890cm²
What is surface area?A solid object's surface area is a measurement of the overall space that the object's surface takes up, and it is always expressed in square units.
The term "surface area" is sometimes used to refer to "total surface area".
Find the sector angle in radians
α = 25× (π/180)
α = (25π)/(180) rad
Find the area of the prism:
A = 2×15×5 + 15×15×α + 5×15×α
A = 150 + 15×15×(25π)/(180) + 5×15×(25π)/(180)
A = 280.890cm²
