Which of the following uses the reciprocal property to rewrite {x}{5} = {72}{4}
A: x/72 = 4/5
B: 5/x = 4/72
C: x/5 = 72/4
D: x/4 = 5/72
Will mark brainliest if answer is correct.
Anw:
a
Step-by-step explanation:
72*4=5x
=288
5x=288
x=288/5
=57.6
x=57.6
57.6/72=0.8
4/5=0.8
Find the area of the shaded region please help
To solve this problem I'd reccomend first finding the area of the circle, then dividing that area by 4 to find the area of the shaded area.
Let's begin!
To find the area of a circle, we will use this formula:
A = (pi) r^2
(pi multiplied by the radius squared)
The radius of a circle is the distance from the center outwards. The diameter goes straight across the circle, through the circle. Radius is basically half of a circle's diameter.
The math problem states that we approximate pi to be 22/7, so we will use that in place of the pi symbol.
Finding the area of the circle:
(pi) r^2 = A
(Write out formula)
(22/7) 12^2 = ?
(Input the values that we now, r equals 12 because that is the radius shown on the image the problem provided.)
22/7 × 144 =
(Start solving, we did 12^2 first)
452 4/7 in^2 (inches squared or square inches)
(Always use your units, math teachers usually don't allow naked numbers. You'll notice that our answer is in fraction form, that's okay if it is, unless your teacher says otherwise, because some teachers prefer answers in decimal form rather than in fraction form)
Now that we know the whole area of the circle, we can finally find the area of the shaded region :)
452 4/7 ÷ 4 = 113 1/7 in^2 (square inches or inches squared)
The area of the shaded region is 113 1/7 in^2
(Hope this helps :) )
An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 13 more than two times the length of the bottom of the triangle. The last side is 11 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.<3

Create a scatter plot and answer the following question.
Graph the points, draw a lint of best fit, and write an equation for the line of best fit.
Answer:
See Explanation.

Best Line of Fit
Algebra II
Linear RegressionStep-by-step explanation:
We can graph the scatter plot and estimate a best line of fit by drawing it in (See Attachment). We can also get the best best of line of fit using your calculator's graphing capacities. The black line is our estimated best line of fit and the red line is the linear regression.
Step 1: Define
Find 2 points from the chart.
Point (1, 2)
Point (7, 7)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute in points [SF]: [tex]\displaystyle m=\frac{7-2}{7-1}[/tex][Fraction] Subtract: [tex]\displaystyle m=\frac{5}{6}[/tex]Step 3: Find Equation
We can roughly estimate the y-intercept of the best line of fit. We see that it is (0, 1.5)
Our equation would then be:
[tex]\displaystyle y = \frac{5}{6}x + \frac{3}{2}[/tex]

Answer:

Step-by-step explanation:,.
Answer:
Terms: 6x², 6x, -4x, -16
Equivalent terms: 6x, -4x
Coefficients: 6 (twice), -4
Constants: 16
Explanation:
A term in an expression is a quantity in that expression. It may include a variable, but it doesn't have to! There are 4 terms in this expression: 6x², 6x, -4x, -16. Remember to put the negative sign in front if the term follows a minus sign.
Equivalent terms have the same variable level. Here, the equivalent terms are 6x and 4x, because they both have x as their variable.
Coefficients appear in front of a variable in a term. There are 3: 6, another 6, and -4.
Constants don't have a variable. There is just one: -16.

Hey there!
The answer to your question is x = 45
To solve this, we want to get x with a coefficient of 1 by itself on one side of the equal sign, and right now it's coefficient is 1/3. We can get a coefficient of 1 by multiplying both sides of the equation by 3.
15(3) = 1/3x(3)
45 = x
