I WILL MARK AS BRAINLIST IF U GET IT RIGHT....... How many proportional relationships are shown in the coordinate plane below?
A. 0
B. 1
C. 2
D. 3
Answer:
c. 2
Step-by-step explanation:
c
Answer:
The answer is D) There are three proportional relationships
Step-by-step explanation:
The green line (the one in the middle) is a straight line through the origin. This is a proportional relationship.
Reason: It goes through 0,0
----------------------------------------------------------------------------------------------------------------
The blue line (the one at the top) is a straight line through the origin. This is a proportional relationship.
Reason: It goes through 0,0
----------------------------------------------------------------------------------------------------------------
The purple line (the one at the bottom) is a straight line through the origin. This is a proportional relationship.
Reason: It goes through 0,0
----------------------------------------------------------------------------------------------------------------
Conclusion: Since the blue, green, and purple lines are proportional, this means all 3 lines are proportional.

Lashawna is making jewelry to sell at a craft fair. On Monday, she makes 12 bracelets. On Tuesday, she works an additional 2.5 hours and has a total of 22 bracelets. Determine the time it takes Lashawna to make one bracelet
Answer:
ok, so she made 10 bracelets in 2.5 hours. 22-12= 10
2.5 ÷10= .25 hours per bracelet
an hour is 60 minutes, so .25 x60= 15 minutes per bracelet

Write an equation of a line in slope intercept form that passes through (6,5) 1 poi
and is parallel to y =-X+4 *
Answer:
y = -x + 11
Step-by-step explanation:
The slope of the line y = -x + 4 is -1.
So the slope of our line is also -1 ( because they are parallel).
First use the point-slope form of the equation of a line:
y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line.
Here m = -1 and (x1, y1) = (6, 5).
So we have:
y - 5 = -1(x - 6)
y - 5 = -x + 6
y = -x + 11 <------ Slope intercept form.

Answer: C. 2 11/25
Step-by-step explanation:
which one is correct?
Answer:
SSS or SAS
Step-by-step explanation:
Remark
Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.
1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.
2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.
solve both of these?
Answer: 1. 18600000000 2. 645000
Step-by-step explanation:
62000000 x 300 = 18600000000
The area of Rhode Island is 1500. The area of Alaska land is a little more than 430.
1500 x 430 = 645000.
(I not sure if 645000 is the correct number, but that’s what I got).
8 6/7 =
i want it in fraction form and in the smallest form.
Answer:
[tex]8\frac{6}{7}[/tex] as an improper fraction is [tex]\frac{62}{7\\}[/tex]
[tex]8\frac{6}{7}[/tex] in simplest form is [tex]8 \frac{6}{7\\}[/tex]
Step-by-step explanation:
To find the improper fraction of 8 6/7 is:
Multiply the denominator of the fraction by the whole number, 8. This gives you 56. Now, add the 56 with the numerator of the fraction. This gives you 62 as a sum. So, the improper fraction is 62/7.
You cannot simplify 8 6/7 because it is in simplest form.

Given the function y=-\frac{3\sqrt{x^5}}{4},y=− 4 3 x 5 , find \frac{dy}{dx}. dx dy . Express your answer in radical form without using negative exponents, simplifying all fractions.
Given:
The function is:
[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]
To find:
The value of [tex]\dfrac{dy}{dx}[/tex].
Solution:
We have,
[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]
It can be written as
[tex]y=-\dfrac{3}{4}x^{\frac{5}{2}}[/tex] [tex][\because \sqrt[n]x=x^\frac{1}{n}][/tex]
Differentiate with respect to x.
[tex]\dfrac{dy}{dx}=-\dfrac{3}{4}\times \dfrac{5}{2}x^{\frac{5}{2}-1}[/tex] [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{5-2}{2}}[/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{3}{2}}[/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}\sqrt{x^3}[/tex]
Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is [tex]-\dfrac{15}{8}\sqrt{x^3}[/tex].
Michelle delivers books to school libraries. her truck has a slide out ramp for unloading the books. the top of the ramp is 3 ft above the ground. the ramp itself is 5.2 ft long. what is the horizontal distance the ramp reaches
Answer:
4.2 ft
Step-by-step explanation:
We can assume that the truck is vertically straight, so this will make up the vertical side of the triangle.
This means that the triangle is a right triangle since a right angle will be formed with the ground and the 3 ft side.
Next, we have the ramp length which is 5.2 ft long. This will be the hypotenuse of the right triangle since the ramp is slanted.
We want to find the length of the horizontal leg of the right triangle, which will give us the horizontal distance the ramp reaches.
We can use the Pythagorean Theorem since this is a right triangle:
a² + b² = c² a and b are the legs, c is the hypotenuseSubstitute these values into the equation and solve for b.
(3)² + b² = (5.2)² 9 + b² = 27.04 b² = 18.04 b = 4.24735211632The horizontal distance the ramp reaches is 4.2 ft, parallel to the ground.

What is length of PR
m PZR is 2/3 pie radius
Answer:
Option (4)
Step-by-step explanation:
m(∠PZR) = [tex]\frac{2}{3}\pi[/tex]
Radius of the circle = 8
Since, length of an arc = [tex]\frac{\theta}{2\pi }(2\pi r)[/tex]
Here, θ = Central angle in radians
From the given formula,
m(arc PR) = [tex]\frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)[/tex]
= [tex]\frac{2}{6}(16\pi )[/tex]
= [tex]\frac{16}{3}\pi[/tex]
Therefore, Option (4) will be the correct option.

A square mat has an area of 324 square inches. What is the length of the mat?
Please help! I don't know this question.
Answer:
B. 14/15
Step-by-step explanation:
I hope this helps.
Answer:
B: 14/15
Step-by-step explanation:
Here's why I say this:
The total is 120. 8 have a box meaning 112 do not have a box. The question is asking about those without a box, so 112 will be used. 112/120. Simply by dividing each the numerator and denominator, in this case by 8. The fraction left is 14/15

Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels
The question is incomplete:
Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels? The table that shows the types of bagels sold at the bagel shop on Friday is attached.
a. $70
b. $20
c. $90
d. $110
Answer:
c. $90
Step-by-step explanation:
First, you need to find the amount of bagels that Sasha purchased. The statement indicates that she buys all the chocolate chip bagels and the table shows that 28 chocolate chips bagels were sold, so that's the amount she purchased of this type of bagels. Also, the statement indicates that she buys half of the plain bagels and the table says that 16 plain bagels were sold, so you have to divide this amount by 2:
16/2=8
Then, you have to add the amount of chocolate chips bagels plus the amount of plain bagels that Sasha purchased:
28+8=36
Now that you know the amount of bagels that Sasha purchased, you have to multiply this for 2.50 that is the price per bagel:
36*2.50=90
According to this, the answer is that Sasha spends $90 on bagels.

Answer:
f(x) = 3x³ +6x² -3x -6
Step-by-step explanation:
Each x-intercept (x=p) gives rise to a factor (x-p), so the factored form of the function is ...
f(x) = a(x -(-2))(x -(-1))(x -1)
The value of 'a' is chosen to make the y-intercept match that shown. The function just written has ...
f(0) = -6 = a(2)(1)(-1)
-6 = -2a
a = 3 . . . . . divide by -2
So, the function in factored form is ...
f(x) = 3(x +2)(x +1)(x -1)
Expanded, this is ...
f(x) = 3x³ +6x² -3x -6
