When plotting to use the form
(X,Y) aka (horizontal, vertical)
Answer:
(-4, -1), (0, 2), (4, 5)
Step-by-step explanation:
(-4, -1): If you see the x-axis and trace -4 and -1 from the y-axis, they both lead to a point that is on the graph.
(-2, 1): The graph, at -2 on the x-axis, lies at height 0.5, so 1 is wrong.
(0, 2): At 0, the graph lies on 2.
(4, 5): At 4 on the x-axis, the graph lies at height 5.
(2, 0): The graph is already at height 3.5 when at length 2.

If 76g of sodium reacts with chlorine to produce 214g of sodium chloride, how many grams of chlorine reacted?
need help
Answer:
138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Step-by-step explanation:
We are given:
Grams of Sodium = 76 g
Grams of Sodium Chloride = 214 g
We need to find how many grams of chlorine required to produce 214 g of sodium chloride
The equation will be:
[tex]Na \ + \ Cl \ -> NaCl\\76\ g \ \ \ x \ g \ \ \ \ \ \ \ \ 214 g[/tex]
We can write: 76 (g) + x (g)=214 (g)
Solving and finding value of x
x =214-76
x=138 g
So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.
Krutika and Natasha win some money and share it in the ratio 3:1. Krutika gets £52 more than Natasha. How much did Natasha get?
Answer:
Step-by-step explanation:
We know that Krutika’s share is three times Natasha’s because they are split in a 3:1 ratio. So we can say:
K=3N
We also know that Krutika’s share is £52 more than Natasha’s:
K= (N+£52)
Substituting what we know about K allows us to reduce the equation to one variable:
3N=N+£52
Clean that up by subtracting N from both sides, leaving us with variables only on one side of the equation.
2N=£52
Which means that we can divide both sides by two to get our answer.
N=£26.
So, of the original £104, Krutika got £78 and Natasha got £26.

7. A recipe for a smoothie calls for 5 cups of strawberries for every 2 cups of bananas. The line represents the relationship between the amount of strawberries and the amount of bananas needed to make a smoothie according to this recipe. The point (1, 2.5) is on the line. Show your reasoning.
Answer/Step-by-step explanation:
This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.
Thus, a constant of proportionality, k, is a ratio that exist between both quantities.
k = y/x = amount of strawberry/amount of bananas.
Since we are given that a recipe of smoothie contains 5 cups of strawberries for every 2 cups of bananas, therefore,
k = ⁵/2 = 2.5.
Any point that will be on the line shown must have the same value of k (y/x).
Thus, given the point (1, 2.5). The ratio between y and x is:
k = 2.5/1 = 2.5.
Since this also shows the same constant of proportionality as 2.5, therefore, the point is also on the line.

This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.

Answer:
b. -2/3
Step-by-step explanation:
in addition a negative plus a negative does not equal a positive so we can already assume the answer is b but to be safe we can work this problem out in this way: 1/9 + 5/9 = 6/9 we simplify 6/9 and we get 2/3 so we slap the negative back on and boom -2/3

describe the effect of change on the area of the rectangle if the base and height are both multiplied by 1/2
Answer:
The area would decrease
Step-by-step explanation:
So if the base was 4ft and the height was 2ft then the area would be 8ft^2. because area is base times height. so if 4 times 1/2 is 2 and 2 time 1/2 is 1 so the area would be 2ft^2

A class measured the radius and circumference of various circular objects. The results are plotted on the graph below. Does there appear to be a proportional relationship between the radius and circumference of a circle? Explain your reasoning
Answer:
I think yes because the circumference is calculated using the equation 2πr ...So with radius the the circumference also get changed according to that...I don't know am I right or not...But just an idea
In triangle JKL, if angle J is seven less than angle L and angle K is 21 less than twice angle L, find the measure of each angle
Answer:
j=45 k=83 L=52
Step-by-step explanation:
j=x-7
k=2x-21
L=x
x-7+2x-21+x=180
4x-28=180
4x=208
x=52
The measure of the angles are; J = 48, K = 57 and L = 75
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
In order to determine the measure of these angles, we have to set J as x. then find the measure of all of these angles.
J = x
K = x + 9
L = 2x - 21
Now, we can add them all together and set equal to 180;
x + x + 9 + 2x - 21 = 180
4x - 12 = 180
4x = 192
x = 48
Now that we have;
J = x = 48
K = x + 9 = 48 + 9 = 57
L = 2x - 21 = 2(48) - 21 = 96 - 21
L = 75
Hence, The measure of the angles are; J = 48, K = 57 and L = 75

A bus driver drives 6 miles a day how many miles does the bus driver drive in 5 days?
Answer:
The bus driver drives 30 miles in 5 days.
Step-by-step explanation:
Hi,
You can use the rule of three to solve this problem.
For the first step, we need to analyze the information given:
[tex]6 (miles) = 1 (day)[/tex]
and we want to know how much miles the bus driver drives in 5 days:
[tex]x (miles) = 5 (day)[/tex]
Thus,
[tex]6 (miles) = 1 (day)[/tex] ... (1)
[tex]x (miles) = 5 (day)[/tex] ... (2)
Now, multiplying in a cross and we have:
[tex]x *1 = 5*6 \\ x = 30[/tex]
Lastly, replacing the value of x in (2):
[tex]30 (miles) = 5 (day)[/tex]
and this is the answer
