Answer:
You would have a horizantal line with a y-intercept of 1.
Step-by-step explanation:
Answer: y is less than or equal to 1
Step-by-step explanation:
Whenever you see parentheses you should automatically think of P.E.M.D.A.S.
Step 1:
In order to get rid of the parentheses you will have to combine like terms, meaning that the 7 will need to be multiplied by whats inside the parentheses.
7 x y = 7y
7 x 2 = 14
Rewritten, your equation should look like this: 7y + 14 - 6 less than or equal to 15
Step 2:
Next, we need to get rid of the 6 which means that 6 should be added in order to cancel it out. 6 should also be added to the other side of the equation.
-6 + 6 = 0
15 + 6 = 21
Rewritten, your equation should look like this: 7y + 14 less than or equal to 21
Step 3:
In order to further balance out the equation, you will need to subtract the 14 from both sides of the equation.
14 - 14 = 0
21 - 14 = 7
Rewritten, your equation should look like this: 7y is less than or equal to 7
Step 4:
Finally, you should divide both sides by seven!
7y/7 = y
7/7 = 1
Rewritten, your equation should look like this: y is less than or equal to 1

Answer:
Step-by-step explanation:
the volume of the aquarium is V= Lx wx H
it is already given that V=11.18 cubic feet, so 11.18=LxWxH
H height and it is the aquarium's depth
H=11.18 / L xW= 11.18/2.7x1.6= 2.58 feet

How do the average rates of change for the pair of functions compare over the given interval?
Answer:
I'm not sure about the given interval but here is how to answer it yourself.
Step-by-step explanation:
To find the average rate of change, we divide the change in y (output) by the change in x (input). And visually, all we are doing is calculating the slope of the secant line passing between two points.

How many yards and feet are equivalent to 10,000 feet? (1 yard = 3 feet)
what are three ratios that are equivalent to 4:3.
Answer:
8:6 , 12:9 , 16:12
Step-by-step explanation:
To find equivalent ratios is like finding equivalent fractions :
We simply multiply both numbers of the ratio by the same number.
You can also do the reverse to simplify a ratio.
4:3 × 2 = (4×2):(3×2) = 8:6
4:3 × 3 = (4×3):(3×3) = 12:9
4:3 × 4 = (4×4):(3×4) = 16:12
Therefore 3 ratios that are equivalent to 4:3 are :
8:6 , 12:9 , 16:12

What is the scale factor from figure A to figure B?
Answer:
1/3
Step-by-step explanation:
Figure A is
-the initial one and
-is bigger
so the scale factor is less then 1 and the figure A was shrunk to figure B
If we compare the sides of the triangles we see that the green triangle was shrunk by a k= 1/3 factor into the blue triangle.
Blue triangle is 3 times smaller than green triangle.

In a bag, there are 100 same-sized chips labeled 1 through 100. If one chip is selected without looking, order the probabilities of the events below by placing the event with the greatest probability on top.
Answer:
a: 89/100
b: 19/100
c: 28/100
Step-by-step explanation:
for a, take every number greater than 10. there are 100 chips, so 89/100 chips are greater than 10. do this for each of the other questions.
The order for the probabilities of the events by placing the event with the greatest probability on top is
1. The label is a number between 30 and 60
2. The label is a number less than 20
3. The label is a number greater than 10
How did we arrive at this order?Below are the correct order of the probabilities from greatest to least:
1. The label is a number between 30 and 60
2. The label is a number less than 20
3. The label is a number greater than 10
The reason for this order is that there are 31 chips with labels between 30 and 60, 19 chips with labels less than 20, and 90 chips with labels greater than 10.
Therefore, the correct answer is as given above.

What is the value of x?
Answer:
A triangle is 180 degrees and you have a 30 and 50 angle so the third angle should equal 100. so the answer should be 45 and here's why
Step-by-step explanation:
Subtract 10 from both sides
2x+10=100
2x+10-10=100-10
Simplify
Subtract the numbers
2x=90
Divide both sides by the same factor
2x=90
2x/2 = 90/2
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
x=45
Solution

Question 1
Center = R
Radius = RS and RP and RQ
Diameter = PRQ
Question 2
Center = C
Radius = CD and CA and CB
Diameter = ACB
Question 3

Miguel draws a square on a coordinate plane. One vertex is located at (5,4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex.
A. (5,1)
B. (5,7)
C. (7,8)
D. (2,6)
E. (2,1)
Answer:
A, B, and E.
Step-by-step explanation:
We know that one vertex is at (5, 4), and each side of our square is 3 units long.
Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3 units (if those vertexes are connected by the diagonal of the square).
Also remember that the distance between two points (a, b) and (b, c) is:
distance = √( (a - c)^2 + (b - d)^2)
So we need to find the distance between our point and all the ones given in the options:
A) the distance between (5, 4) and (5, 1) is:
distance = √( (5 - 5)^2 + (4 - 1)^2) = 3
Then point (5, 1) can be a vertex.
B) The distance between (5, 4) and (5, 7) is:
distance = √( (5 - 5)^2 + (4 - 7)^2) = 3
Then (5, 7) can be a vertex.
C) The distance between (5, 4) and (7, 8) is:
distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20
Point (7, 8) can not be a vertex.
D) The distance between (5, 4) and (2, 6) is:
distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13
Point (2, 6) can not be a vertex.
E) The distance between (5, 4) and (2, 1) is:
distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3
Then point (2, 1) can be a vertex.
Carly placed 50 marbles in a bag. Fifteen of the marbles are pink, 8 marbles are black,
2 marbles are green, 18 marbles are clear, and 7 marbles are striped. Click and drag
the letters onto the probability scale to order the likelihood that the event will happen.
When you go into this problem, you want to figure out your marble ammount to 50 so in this case we will say C for color and 50 for the total ammount of marbles.
We know 15 are pink, 8 are black, 2 are green, 18 are clear, and 7 are striped
15P/50
8B/50
2G/50
18C/50
7S/50 for a total of 50 marbles
Now we use the chart to decide our awnsers
A. We know our propability of drawing a green and clear is 20/50 which if we simplify is a 2/5 ratio. If We put this in perspective 2/5 is rare and is unlikley to even.
B. We know a striped marble is 18/50 or 1.8/5 ratio which is mainly unlikely
C. We have 23/50 marbles that are black and pink, our propability is about 2.3/5 and gives us an even chance to get one of these
D. We know we have 33/50 marbles that are pink and clear and gives us a 3.3/5 chance of getting one of these and gives us an even to likely chance of getting one of these.
E. If we have a total of 17 marbles in these 3 colors, we have a 1.7/5 chance of getting one of these and is probably impossible to unlikey.

Answer:
B
Step-by-step explanation:
Because the pythagorean theorem we know that s2 = r2 + h2, since r = a/2s2 = (1/4)a2 + h2, and s = √(h2 + (1/4)a2)
