Alonzo buys cheese from the local farmers market the graph below shows the cheese cost in cents versus its weight in ounces use the graph to answer the questions
Answer:
35 cents per 1oz
Step-by-step explanation:
there is a slope of 1 so the cost of 1 oz is equal to (1,1)
find (x+55)°
find (3x-5)°
find x
Answer:
x = 30
Step-by-step explanation:
The two angles are congruent so they have the same value
3x-5 = x+55
Subtract x from each side
3x-5 -x = x+55-x
2x-5 = 55
Add 5 to each side
2x-5+5 = 55+5
2x= 60
Divide each side by 2
2x/2 = 60/2
x = 30
You would get
x=40

Answer: A.
Step-by-step explanation: There are a few outliers in A which would generally distort the shape of a dot plot where a majority would be clustered around the mean, and the points off to the side would fall far away from the mean making it skewed right in this situation.

A flying carpet flies 2.4 miles with the wind in the same amount of time it flies 1.4 miles against the wind. The wind speed is 4 mph. What is the speed of the flying carpet in still air?
Answer:
[tex]15.2~mph[/tex]
Step-by-step explanation:
Let the time flown by the flying carpet be [tex]t[/tex]. Then, we have that [tex](2.4)/t=(1.4)/t+2*4[/tex].
We multiply both sides of the equation by [tex]t[/tex] to get [tex]2.4=1.4+8t[/tex].
We subtract [tex]1.4[/tex] from both sides to get [tex]1=8t[/tex].
We divide both sides of the equation by [tex]t=1/8[/tex].
We know that the speed of the flying carpet in still wind is the average of the rates of the speed of the flying carpet with the wind and against the wind.
The speed with wind is [tex](2.4)/(1/8)=19.2[/tex]mph.
The speed against wind is [tex](1.4)/(1/8)=11.2[/tex]mph.
The speed in still wind is [tex](19.2+11.2)/2=(30.4)/2=15.2[/tex].
Therefore, the answer is [tex]\boxed{15.2~mph}[/tex] and we're done!
The speed of the flying carpet in still air is 15.2 mph
Let x represent the speed of the flying carpet in still air, and t represent the time.
Speed = distance/time
Since the wind speed is 4 mph, hence:
When flying with the wind:
x + 4 mph = 2.4/t (1)
When flying against the wind:
x - 4 mph = 1.4/t (2)
Dividing equation 1 by 2 gives:
(x + 4) / (x - 4) = 2.4/1.4
1.4x + 5.6 = 2.4x - 9.6
x = 15.2 mph
The speed of the flying carpet in still air is 15.2 mph

Complete the missing value in the solution to the equation.
(8.

Answer:
The answer is 5
Step-by-step explanation:
Since we already know what x we can just substitute it.
5(8)-2y=30
5 times 8 is 40
40-2y=30
Subtract 40 on both sides:
-2y=-10
Divide -2 on both sides:
y=5

Three teams, A, B and C, play in a competition.
games won by A: games won by B = 4:3
games won by B: games won by C = 5:2
Team B has won 30 games.
In total, how many games have the three teams won?
ANSWER:
43
Explanation:
A : B : C
4 : 3
5 : 2
A × B → 4 × 5 = 20
B × B → 3 × 5 = 15
B × C → 3 × 2 = 6
A : B : C
20 : 15 : 6
B = 15 = 30
what of teams A and C together?
If 15 = 30games, what about 26games?
Cross multiply.
15 × 26 =13
30
So, games won by Team B + games won by Teams A and C
30games + 13games
=43games.

The length of the side of a square whose area is 225 m² is _____.
Answer:
15
Step-by-step explanation:
Answer: 15
Step-by-step explanation:
you would have to find the square root of 225 and this is 15 so if you do 15x15 you will get 225
and if you need to find the perimeter you add up all the sides
15x4=60
The perimeter of a square is 60
1 side length of a square: 15

Simplify the expression -5+i/2i
Step by step
Answer:
For complex numbers,
a + bi and a - bi
they have the interesting property that if you add them you get the real number 2a
and if you multiply them , because of the difference of square pattern, you get a^2 - b^2 i^2
But since i^2 = -1, we end up with a real number as a product.
e.g. 6 - 5i and 6 + 5i are conjugates of each other
sum = 6-5i + 6+5i = 12
product = 36 - 25i^2
= 36 -(-25) = 61
Your question is even easier, since the denominator is a monomial instead of a binomial, so we just have to multiply by i/i
Also I believe, according to the answer, that you have a typo, and you meant
(-5+i)/(2i)
= (-5+i)/(2i) *i/i
= (-5i + i^2)/2i^2)
= (-5i +i^2)/-2
= (-5i - 1)/-2
= (1 + 5i)/2 or they way they have it: 1/2 + 5i/2
