What do opposite rays form
Answer:
they form a single straight line:)
Answer:
a line
Step-by-step explanation:
Here is ray AB
A B
+----------------------+------------------->
It starts at point A, goes through point B, and goes only in one direction, to the right. Points A and B lie on line AB.
Now I'll add an opposite ray whose endpoint is also point A.
C A B
<-----------+--------------+----------------------+------------------->
Ray AC also lies on the same line as ray AB, but starting at point A, it goes in the opposite direction of ray AB. When you add ray AC to its opposite ray AB, you get the entire line AB.

What is the value of y?
What is the area, in square inches, of the rectangle
Answer:
Part A: y = 3
Part B: Area = 60 sq units
Step-by-step explanation:
we can create this system of equations from the information given:
8y + 2x = 34
10y + 2x = 40
now we can subtract to get:
-2y = -6
y = 3
solve for 'x':
8(3) + 2x = 34
24 + 2x = 34
2x = 10
x = 5
Area of Rectangle is 12 x 5
I don’t get this Need help asap
Answer:
Step-by-step explanation:
x - 2y =8
-2y = -x + 8
[tex]y = \frac{-1}{-2}x+ \frac{8}{-2}\\\\y =\frac{1}{2}x - 4[/tex]
When x = 4,
[tex]y = \frac{1}{2}*4-4\\\\ = 2-4\\\\y = -2[/tex]
(4, - 2)
When x = -4,
[tex]y =\frac{1}{2}*(-4) - 4\\\\ = -2 - 4\\\\= - 6[/tex]
(-4, -6)
Plot the points (4, -2) and (-4 , -6) in the graph and Join the points

Answer:
∠W = 130∠X = 140∠Y = 50∠Z = 40Step-by-step explanation:
Using 'y' and 'z' to represent angles with the corresponding names, we have ...
y + z = 90
(3b -1) +(2b +6) = 90 . . . . substitute the given expressions
5b +5 = 90 . . . . . . . . . . . . simplify
b +1 = 18 . . . . . . . . . divide by 5
b = 17 . . . . . . . . subtract 1
Then the angles are ...
y = 3b -1 = 3(17) -1 = 51 -1 = 50
z = 2b +6 = 2(17) +6 = 34 +6 = 40 . . . . note that these are complementary, as theys should be
Angles W and Y form a linear pair, so are supplementary:
W = 180 -Y = 180 -50 = 130
Angles X and Z form a linear pair, so are supplementary:
X = 180 -Z = 180 -40 = 140
Then the angle measures are ...
∠W = 130∠X = 140∠Y = 50∠Z = 4015 points for this question

Answer:
[tex]f(a) = 5a + 1[/tex]
[tex]f(a + h) = 5a + 5h +1[/tex]
[tex]\frac{f(a + h) - f(a)}{h} =5[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 5x + 1[/tex]
Solving (a): f(a)
Substitute a for x in [tex]f(x) = 5x + 1[/tex]
[tex]f(a) = 5a + 1[/tex]
Solving (b): f(a + h)
Substitute a + h for x in [tex]f(x) = 5x + 1[/tex]
[tex]f(a + h) = 5(a + h) +1[/tex]
Open bracket
[tex]f(a + h) = 5a + 5h +1[/tex]
Solving (c): [tex]\frac{f(a + h) - f(a)}{h}[/tex]
In (a):
[tex]f(a) = 5a + 1[/tex]
In (b):
[tex]f(a + h) = 5a + 5h +1[/tex]
So:
[tex]\frac{f(a + h) - f(a)}{h} =\frac{5a+5h+1 - (5a+1)}{h}[/tex]
Open bracket
[tex]\frac{f(a + h) - f(a)}{h} =\frac{5a+5h+1 - 5a-1}{h}[/tex]
Collect Like Terms
[tex]\frac{f(a + h) - f(a)}{h} =\frac{5a- 5a+5h+1 -1}{h}[/tex]
[tex]\frac{f(a + h) - f(a)}{h} =\frac{5h}{h}[/tex]
[tex]\frac{f(a + h) - f(a)}{h} =5[/tex]
math help lol say hi point for lolll
Solving steps and answer!
Answer:
[tex]h = 162.0\ cm[/tex]
Step-by-step explanation:
Given
[tex]BSA = \frac{\sqrt{w*h}}{60}[/tex]
Required
Find h, when BSA = 1.5 and w = 50
We have:
[tex]BSA = \frac{\sqrt{w*h}}{60}[/tex]
Substitute 1.5 for BSA and 50 for w
[tex]1.5 = \frac{\sqrt{50*h}}{60}[/tex]
Multiply both sides by 60
[tex]60*1.5 = \frac{\sqrt{50*h}}{60}*60[/tex]
[tex]60*1.5 = \sqrt{50*h[/tex]
[tex]90 = \sqrt{50*h[/tex]
Square both sides
[tex]90^2 = (\sqrt{50*h})^2[/tex]
[tex]90^2 = 50*h[/tex]
[tex]90^2 = 50h[/tex]
[tex]8100 = 50h[/tex]
Divide both sides by 50
[tex]\frac{8100}{50} = \frac{50h}{50}[/tex]
[tex]\frac{8100}{50} = h[/tex]
[tex]162 = h[/tex]
[tex]h = 162[/tex]
[tex]h = 162.0\ cm[/tex]
Hence, the patient's height is 162.0cm
10.Suppose that you have bought 3 large glass-fronted cabinets. You have three workers, A, B and C, to help you with transporting the cabinets from the furniture store to your home, and you want them to finish it in (at most) one trip each. From past experience, it is known that the probability that A breaks something in a given trip is 10%, the probability that B breaks something in a given trip is 15%, and the probability that C breaks something in a given trip is 20%. The events that A, B, or C breaks something in a given trip are independent of each other. You come up with three strategies: (a) A transports all the furniture, (b) A transports two cabinets and B transports one cabinet, or (c)
Answer:
Step-by-step explanation:
To find the expected no of broken cabinets for each strategy.
If A transport all the furniture
Suppose X₁ = number of furniture A broken
X₁ follows a binomial with n = 3, p = 0.10
E(X₁) = np
E(X₁) = 3 × 0.1
E(X₁) = 0.3
If A transport two (2) cabinets & B transport one (1) cabinet
expected no. of the broken cabinet by A out of 2 is
= 2 × 0.1
= 0.2
Suppose X₂ denotes the no of broken furniture by B
E(X₂) = np
where n= 1 and p = 0.15
E(X₂) = np
E(X₂) = 1 × 0.15
E(X₂) = 0.15
Thus. the expected number of broken cabinets = 0.2 + 0.15 = 0.35
Suppose 50% of the people in a particular population have high blood pressure. Of the people with high blood pressure, suppose 75% smoke; whereas, only 50% of the people without high blood pressure actually smoke. What percent of people who smoke have high blood pressure
Answer:
37.50%
Step-by-step explanation:
The computation of the percentage of people who smoke have high blood pressure is shown below:
Given that
There is 50% of the people who has the high blood pressure
And, out of which 75% would smoke
So, the percent of the people who smoke have high high blood pressure is
= 50% × 0.75
= 37.50%

Alma and Crystal went out to et and spent $16. They wanted to tip the waitress 15%, what was the total cost of their meal including tip?
A: 2.40
B: 18.40
C: 4.80
D: 46.80
Answer:
B: $18.40
Step-by-step explanation:
100% is equal to $16 so 5% would be 16/20 or $0.80 then to get 15% you would multiply $0.80 by 3 which is $2.40. This is the tip. Then do $16 + $2.40 and the total + tip is $18.40. (Double check to make sure I'm correct)

what is the surface area of this shape ?
Answer:
what is the surface area of this shape? 328 yd
Step-by-step explanation:
Surface area = 2 × (11×8 + 11×4 + 8×4)
Surface area = 2 × (88 + 44 + 32)
Surface area = 2 × 164
Surface area = 328 yd
