Solve for y: (1/2)y + 1/2 =
3 1/2
Answer:
Step-by-step explanation:
1/2y + 1/2 = 3 1/2
- 1/2 -1/2 subtract 1/2 on both sides to isolate 1/2y
1/2y = 3 divide both sides by 1/2 to get y value
y = 6

The amount of air pressure, (PSI) in the spare tire of a certain vehicle (Type A) brought for inspection are normally distributed with PSI of µ = 30 and σ = 4, and such spares tires with PSI below 25 are considered under-inflated.
The amount of air pressure, (PSI) in the spare tire of a certain vehicle (Type B) brought for inspection are normally distributed with PSI of µ = 27.7 and σ = 5.4, and such spare tires with PSI below 25 are considered under-inflated.
The PSI found in the spare tire of vehicle Type A and vehicle Type B does not depend upon the other type of vehicle, and every vehicle has 1 spare tire in it.
a. What is the probability that, for the next Type A vehicle and next Type B vehicle that are inspected, that BOTH vehicles have an under-inflated spare tire?
b. What is the probability that, for the next Type A vehicle and next Type B vehicle that are inspected, that there is a total of EXACTLY one under-inflated spare tire among these two vehicles?

Which equation represents the number of points in the problem below?
A test is worth 60 points. Multiple-choice questions are worth 2 points, and
short-answer questions are worth 5 points. If the test has 15 questions, how
many multiple-choice questions are there?
O A. 2m+ 5s = 60
B. m + s = 60
O C. 2m + 5s +15 = 60
O D. 2m + 5s = 15
Answer:
Step-by-step explanation:
Let the number of MC questions = x
Let the number of SA questions = y
x + y = 15
2x + 5y = 60
Multiply the top equation by 2
2x + 2y = 30
Put this underneath the second equation and subtract
2x + 5y = 60
2x + 2y = 30 Subtract
3y = 30
y = 10 Subtract
2y = 20
y = 10
x + y = 15
x + 10 = 15
x = 5
If b^2=a then b is what of a?
Answer:
[tex]\huge\boxed{b = \sqrt{a}}[/tex]
Step-by-step explanation:
If we have an equation [tex]b^2 = a[/tex] and we want to find what b is in relation to a, we can change the equation so that we have b on one side and whatever is on the other side is what b is.
[tex]b^2 = a[/tex]
To isolate b, we can take the square root of both sides as taking the square root of something squared results in the base.
[tex]\sqrt{b^2} = \sqrt{a}[/tex]
[tex]b = \sqrt{a}[/tex]
So b is the square root of a.

The ratio of soccer balls to basketballs at Andrew’s school is shown on the ratio table. What number completes the ratio table to make an equivalent ratio? [Type your answer as a number.]
soccer balls 30 __?
basket balls 25 5
Answer:
Step-by-step explanation:
You can set this up as a proportion
30/25 = x/5
Cross multiply
25*x = 30*5
25*x = 150
x = 150/25
x = 6
Answer:
30 to 150
25 to 5
Step-by-step explanation:
if there are 25 basketballs for every 5 soccer balls, that means that there is 1 soccer ball for every 5 basketballs. so to get how many soccer balls to basket balls, you would multiply 30 by 5 to get 150. For every 30 soccer balls there are 150 basketballs.

X intercepts are when y = 0, set the equation equal to zero and solve:
0 = -x^3 +x^2 + x -1
-x^3 + x^2 = -x
-x + x = 0
0-1 = -1
The first one is (-1,0)
Because the equation contains squares the answer could also be opposite, so the other answer would be (1,0)
The two answers are (-1,0) (1,0)

The area of a triangle that has 11m height and 12m base
Answer:
The answer for base is 10 and the answer for height is 20 and the answer for unit is cm Area = 100 in2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Area = 1/2 b * h
b = 12 m base
h = 11 meters
Area = 1/2 * 12 * 11
Area = 1/2 * 132
Area = 66 square meters.
the length of a rectangle is five times its width. if the perimeter of the rectangle is 96 ft, find its area.
Answer:
lets say that the length is L and the width is W. With the given info, we can say that L=5W.
We know that the perimeter is all four sides added, so..
5W*4=20W
20W=96
W=4.8
L= 5*4.8=24
Area is equal to 24*4.8, which is 115.2
Voila! Your answer is 115.2 sq. ft!

What is unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A unit rate is a rate in which.....
Now, if we find the unit rate of any quantity it tells that the price of 1 quantity.
It does not tell about the amount of quantity.
