Answer:
Step-by-step explanation:
y = 6X
so this is a direct variation , b/c as X goes up, so does Y
The equation that models the data is y = 6x
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
To determine whether the data in the table represents a direct or inverse variation, we need to check whether the ratio of x to y is constant.
When we divide each y-value by its corresponding x-value, we get the ratios:
6/1 = 6
12/2 = 6
30/5 = 6
60/10 = 6
We see that the ratio of y to x is constant, which means that the data represents a direct variation.
To write an equation to model the data in the table, we can use the formula for direct variation, which is:
y = kx
where k is the constant of variation.
To find k, we can use any of the given data pairs.
For example, we can use the first pair (x = 1, y = 6):
6 = k(1)
Solving for k, we get:
k = 6/1 = 6
Thus,
The equation that models the data is y = 6x

Answer: 8 1/8
Step-by-step explanation:
What is the value of x in the figure? Enter your answer in the box.
Answer:
65
Step-by-step explanation:
2x+15 = 145
2x = 145-15
2x = 130
x = 65
Answer:
I think x=65
Step-by-step explanation:
Since both of the angles are vertical to one another that would mean they are equal to each other. When writing 2x +15=145 you would solve for x.

the first step is to convert the diameter into a radius measure by using the formula d=2r
when we solve the formula the radius is calculated to be 1.5
use the surface area formula above and your height and radius measurement to find out the area of sheet metal you would need.
2pi(1.5)^2+2pi(1.5)(5)
using 3.14 for pi this equates to 61.23in^2

Use the Pythagorean Theorem to find the missing length and then round the
result to the nearest tenth.
b = 2, c = 3
a =
Answer:
A=2.2
Step-by-step explanation:
PYTHAGOREAN THEOREM:
a^2+b^2=c^2
STEP 1:
Lets put in the given number into the Theorem.
x^2+ 2^2= 3^2
I put x in the "a" place because there is no Number that goes into there, so we put in a variable.
STEP 2:
We find the numbers, which are
x^2+4=9
STEP 3:
We then subtract by 4 from both sides, (We do this because x is not the Hypotenuse)
After subtracting from both sides we have
x^2=5
STEP 4:
Once we have that, we have to find the square root of 5 which is 2.23606798
STEP 5:
Since you say to round to the nearest tenth, we get 2.2
TIP: If the answer didn't have to be rounded to the nearest tenth the answer would've been: [tex]x=\sqrt{5}[/tex] Which is the same as 2.23606798.

There will be Elizabeth and Izak record the number of miles they bike each day. The line plots show the distances they each biked for 5 days. How much greater was the shortest distance Izak biked than the shortest distance Elizabeth biked in 1 day
Answer:
See Explanation
Step by step Explanation:
The question is incomplete as the plots that show the distance traveled is not given.
So, I will answer the question with the attached plots.
The number of dots on each day represents the number of miles travelled on that day.
From Elizabeth's plot, the shortest is 1 mile on day 4 (i.e. 1 dot on day 4)
From Izak's plot, the shortest is 2 miles on day 3 (i.e. 2 dots on day 3)
Calculate the difference between both distances
[tex]d = 2\ miles - 1\ mile[/tex]
[tex]d = 1\ mile[/tex]
Hence, the shortest distance travelled by Izak is 1 mile more than the shortest by Elizabeth

James goes out to eat with Janet, and their meal costs $68. There is a sales tax of 7% and Janet wants to leave a 20% tip. How much money will Janet spend on the entire meal?
Answer:
$86.36
Step-by-step explanation:
Tax: 7%, or 0.07
Tip: 20%, or 0.2
Substitute the values:
Tip: 68 * 0.07 = 4.76
Tip: 68 * 0.2 = 13.6
Just the meal cost: 1 * 68 = 68
Add these all together
4.76 + 13.6 + 68 = 86.36
Thus, the total cost of the meal would be $86.36

Is 3/4greater or less than 1/2....is it 1/2?
Answer: yes 3/4 is greater
converting both fractions to decimals. The decimal 0.75 is bigger than 0.5, so 3/4 is bigger than 1/2.
Answer:
3/4 is greater than 1/2.
Step-by-step explanation:
One way to compare fractions is by making them have the same denominator.
You can do this by finding the least common denominator (LCM).
First, list the multiples of each denominator.
4: 4, 8, 12, 16, 20
2: 2, 4, 6, 8, 10
As you can see, 4 is the LCM.
Now, change the fractions to where they denominators of 4.
**WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MUST ALSO MULTIPLY IT BY THE NUMERATOR.**
[tex]3/4*1/1=3/4[/tex] (STAYS THE SAME)
[tex]1/2*2/2=2/4[/tex]
Now, as you can see, 3/4 is larger than 2/4.
Therefore, 3/4 is larger than 1/2.

D..HOPE IT HELPEDFind the distance between the two points rounding to the nearest tenth (if necessary).
(-6, 6) and (-3,3)
Answer:
[tex]\boxed {\boxed {\sf d\approx 4.2}}[/tex]
Step-by-step explanation:
The formula for distance is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Where (x₁, y) and (x₂, y₂) are the points.
We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:
x₁= -6 y₁ = 6 x₂ = -3 y₂ = 3Substitute the values into the formula.
[tex]d= \sqrt{ (-3 - -6)^2+(3-6)^2[/tex]
Solve inside the parentheses.
-3 --6 = -3+6 = 33-6 = -3[tex]d= \sqrt{(3)^2+ (-3)^2[/tex]
Solve the exponents.
(3)²= 3*3= 9 (-3)²= -3*-3 =9[tex]d= \sqrt{9+9[/tex]
Add.
[tex]d= \sqrt18[/tex]
[tex]d= 4.24264069[/tex]
Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.
[tex]d \approx 4.2[/tex]
The distance between the two points is apprximately 4.2
