Answer: 6
Step-by-step explanation:
What is the y-intercept of the equation 2x + 3y = 12?
- 2/3
6
12
4
Answer:
A ) -2/3
Step-by-step explanation:
Rewrite the equation in slope-intercept form.
y = mx + b
2x + 3y = 12
2x - 2x + 3y = 12 - 2x
3y = 12 - 2x
3y/3 = 12/3 - 2x/3
[tex]y = -\frac{2}{3} x + 4[/tex]
Answer:
The answer above is correct!

50 to 60 as a fraction in simplest form
Answer:
5/6
Step-by-step explanation:
50/60 in simplest form is 5/6
You would divide both sides by 10
The simplified expression of the expression 50 to 60 is 5/6
How to simplify the expressionFrom the question, we have the following parameters that can be used in our computation:
50 to 60
Express as equation
50 to 60 = 50/60
Divide 50 by 60
So, we have the following representation
50 to 60 = 5/6
Using the above as a guide, we have the following:
The expression cannot be further simplified
Hence, the simplified expression is 5/6

Which sets of side lengths could from a triangle?
choose all that apply.
Answer:
E
Step-by-step explanation:
Answer:
d and e
Step-by-step explanation:
for them to be possible side lengths of a triangle the two shorter sides added together have to be greater than the longest side and an answer D and e 6 + 4 is greater than 9 and 5 + 5 is greater than 9 to so those are possible side lengths

If departure time of a train is 03 45 and arrival time is 04 50. What will be the journey time? * A)1 h 20 min B)1 h 10 min C)1 h 05 min
Answer:
C)1 h 05 min
Step-by-step explanation:
If departure time of a train is 03 45 and arrival time is 04 50. What will be the journey time? * A)1 h 20 min B)1 h 10 min C)1 h 05 min
The journey time is calculated as:
Arrival time - Departure time
= 04:50 - 03:45
= 01:05
Therefore, the journey time = 1 hr 05 minutes
Option C is correct

Step-by-step explanation:
Here, we want to calculate the probability that a student who plays an instrument is in band
The number of students who play instruments are;
25
Amongst this,
20 are in a band
So the probability of having a student who plays instrument and is in a band will be;
20/25 = 4/5

A train traveled 1/4 of the distance between two cities in 2/3 of an hour. at this rate, what fraction of the distance can the train travel in one hour
====================================================
Explanation:
A = fraction of the distance traveled in 2/3 of an hourB = time value that pairs up with AC = fraction of the distance traveled in 1 hourD = time value that pairs with CIn this case,
A = 1/4B = 2/3C = unknownD = 1We can set up the proportion
A/B = C/D
Which cross multiplies to
A*D = B*C
Let's plug in the known values and solve for C
A*D = B*C
(1/4)*(1) = (2/3)*C
1/4 = (2/3)*C
(2/3)*C = 1/4
3*(2/3)*C = 3*(1/4) ..... multiply both sides by 3
2C = 3/4
(1/2)*2C = (1/2)*(3/4) .... multiply both sides by 1/2
C = (1*3)/(2*4)
C = 3/8
The train travels 3/8 of the distance in 1 hour.

Find the slope of the line through each pair of points.
Type your answer as a fraction.
(-2, 6), (10, -5)
Answer:
m= -11/12
Step-by-step explanation:
Answer:
-11 / 12
Step-by-step explanation:
Slope = Rise / Run
Slope = y2 - y1 / x2 - x1
Slope = -5 - 6 / 10 - -2
Slope = -11 / 12

2. If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is needed to cover the entire wall?
A) 8 2/3 gallons
B) 8 1/3 gallons
C) 3 gallons
D) 2 gallons
Please help !
Answer: 4 gallons.
Step-by-step explanation:
With this equation, we can use the ratio 1/2 : 1/8. For every 1/2 gallon of paint, 1/8 of a wall is painted.
If 1/2 gallons covers 1/8 of a wall, then we need 8 of the 1/2 gallons to cover the whole wall. We canrepresent this by multiplying 8 and 1/2.
8 x 1/2 = 4.
Because of this, 4 gallons of paint are needed to cover he entire wall.
(Quick note: I don't know why, but the answer choices seem kind of weird. But the answer is 4 :])

Answer:
(x, y) = (-8, 19)
Step-by-step explanation:
9x + 3y = -15
-4x - 3y = -25
(9x + 3y) + ((-4x) - 3y) = -15 + (-25)
5x = -40
x = -8.
So,
9x + 3y = -15
9 * (-8) + 3y = -15
-72 + 3y = -15
3y = 57
y = 19

Randy wanted to survey to determine the most preferred pet of the residents in his city.Which method of samplingBEST represents the most unbiased opinion?
Answer:
Survey 100 residents who have pets completely randomly
Step-by-step explanation:
The best sampling method would be to Survey 100 residents who have pets completely randomly. This would provide first-hand information from actual pet owners which would make the results valid. Also, by choosing the individuals to survey completely randomly it allows for the data to be unbiased and representative of the entire pet owner population in the city. This makes the data gathered completely unbiased and valid.

8. Each box in a set of decorative storage boxes is a cube.
a) The sides of the smallest box are 30% of the length of the sides of the largest
box. The volume of the largest box is 7784 cubic inches more than the
volume of the smallest box. Define one or more variables, and write an
equation that represents the situation.
b) What are the lengths of the sides of the largest and smallest boxes?
c) Two of the other boxes have a total volume of 2457 cubic inches. The length
of the sides of the smaller of these boxes is 75% of those of the larger box.
Write and solve an equation to find the lengths of the sides of the boxes.
Answer:
20 in and 6 in12 in and 9 inStep-by-step explanation:
a) Let the side of the larger box be x, then the side of the smaller box is 0.3x.
Their volumes are:
x³ and (0.3x)³ = 0.027x³The difference in volumes:
x³ - 0.027x³ = 77840.973x³ = 7784x³ = 7784/0.973x³ = 8000x = ∛8000x = 20b) The sides are 20 in and 20*0.3 = 6 in
c) The other two boxes with sides x and 0.75x
Sum of the volumes:
x³ + (0.75x)³ = 2457x³ + 0.421875x³ = 24571.421875x³ = 2457x³ = 2457/1.421875x³ = 1728 x = ∛1728x = 12Sides of the boxes are 12 in and 12*0.75 = 9 in
