he tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.
Cara’s Flower Arrangements
White 3 6 9 12 15
Yellow 5 10 15 20 25
Hector’s Flower Arrangements
White 4 8 12 16 20
Yellow 6 10 14 18 22
Part A
Are the numbers of white and yellow flowers in Cara’s arrangements proportional?
Which equation relates the number of white flowers, w, to the number of yellow flowers, y?
Yes; y=35w
Yes; y=53w
No; y=3w+5w
No; y=5+3w
Part B
Are the numbers of white and yellow flowers in Hector’s arrangements proportional?
Which equation relates the number of white flowers, h, to the number of yellow flowers, e?
Yes; e=32h
Yes; e=23h
No; e=h+2
No; e=h−2
Answer:
A.
1. no, y = 5 + 3w
B.
no, e = h + 2
Step-by-step explanation:
Using the principle of proportional relationship to model the two tables, we can infer that, the first first table is proportional while the second isn't.
Clara's arrangement :
White (w)Yellow (y)Testing if relationship is proportional :
y = kw5 = 3k
[tex] k = \frac{5}{3}[/tex]
Yes, the relationship is proportional [tex] y = \frac{5}{3}w[/tex]
Hector's arrangement :
White (h)Yellow (e)The number of yellow flowers surpasses the number of white flowers by a constant value of 2.
Hence, the relationship can be modeled thus ;
e = h + 2Therefore, the relationship is not proportional.

It takes Krys and Glen 1_4hour to walk a mile. This week Krys walked 9 miles and Glen walked 3 miles. How much longer did Krys walk than Glen?
Answer:
Krys walked 1 1/2 hours longer than Glen.
Step-by-step explanation:
Glen walked 3 miles
3 x 1/4 = 3/4
Krys walked 9 miles
9 x 1/4 = 9/4
9/4 - 3/4 = 6/4
6/4 = 1 2/4
1 2/4 = 1 1/2

What is the distance between (-8, 5) and (6, 5)?
Enter your answer in the box.
___ Units
Answer:
distance: 14
explanation:
[tex]\sf \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
given:
(-8, 5) and (6, 5)solve:
[tex]\sf \rightarrow \sqrt{(5-5)^2+(6--8)^2}[/tex]
[tex]\sf \rightarrow \sqrt{(0)^2+(14)^2}[/tex]
[tex]\sf \rightarrow \sqrt{14^2}[/tex]
[tex]\sf \rightarrow 14[/tex]
Solution:
We know that:
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
Finding the coordinates
(x₁,y₁) = (-8,5) = x₁ = -8; y₁ = 5(x₂,y₂) = (6,5) = x₂ = 6; y₂ = 5Substitute the coordinates into the distance formula.
[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6- (-8)]^{2} +[5-5]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[(6 + 8]^{2} +[0]^{2}}[/tex]
[tex]\rightarrow \text{Distance }=\sqrt{[14]^{2}[/tex]
[tex]\rightarrow \boxed{\text{Distance }=14 \ \text{units}}[/tex]

Every 14 days, Debbie’s dog eats 4 1/5 pounds of dog food. If Debbie’s dog eats the same amount of food each day, how many pounds does her dog eat per day?
The amount of food her dog eat per day would be; 0.33 pound.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that Debbie’s dog eats 21/5 pounds of dog food every 14 days. Debbie’s dog eats the same amount of food each day.
Therefore,
21/5 pounds of dog food = 14 day
one day = 14 / (21/5 ) pounds of dog food
One day = 14 x 5/ 21
= 10/3
Therefore, the amount of food her dog eat per day would be; 0.33 pound.

Step-by-step explanation:
In this question as two straight lines intersect each other
we use vertically opposite angle axiom
so 74 degree = 2x.
then x= 74/2= 37degree
Answer:
Angle 74 degrees and 2x are vertical, so they would have to equal each other.
Note: Vertical angles are congruent meaning they measure the same degrees
So we set up the equation;
74 = 2x
/2 /2
37° = x

What is the slope of the line?
Answer:
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Tod hunter (1888) who wrote it as "y = mx + c".
Step-by-step explanation:
Steps for Graphing a Line With a Given Slope
Plot a point on the y-axis. (In the next lesson, Graphing with Slope Intercept Form, you will learn the exact point that needs to be plotted first. For right now, we are only focusing on slope.)Look at the numerator of the slope. Count the rise from the point that you plotted. If the slope is positive, count up and if the slope is negative, count down.
Look at the denominator of the slope. Count the run to the right.
Plot your point.
Repeat the above steps from your second point to plot a third point if you wish.
Draw a straight line through your points.
Answer: as you can see the line only on the 1

- 3 times as many
- 30 times as many
- 300 times as many
- 3 x 10^6 times as many
Divide the number of people in California (3.9x10^7) by the number of people in Maine (1.3x10^6)
(3.9x10^7) / (1.3x10^6) = 30
