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

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.
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.

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

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

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

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.

what is the slope of a line that has a y-intercept but no x intercept
Answer:
The slope of a line that has a y-intercept but no x-intercept will be zero.
Step-by-step explanation:
If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.
If a line does not have an x-intercept, it means it would never intersect the x-axis.
Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.
For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.
Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.
