Answer:
Part A - Yes; y=5/3w Part B - No; e=h+2
Step-by-step explanation:
The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.
Cara’s Flower Arrangements Proportional
White 3 6 9 12 15
Yellow 5 10 15 20 25
Hector’s Flower Arrangements Not Proportional
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=3/5w
Yes; y=5/3w CORRECT ANSWER
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=3/2h
Yes; e=2/3h
No; e=h+2 CORRECT ANSWER
No; e=h−2
They are correct because Part A is 1.666667 thats more than 1 so it cant be the first, and Part B, its the White flowers plus 2 to be Yellow flowers, not -.

Write an equation in slope-intercept form for the line with slope -1/4 and -7 y-intercept. NO LINKS.
Answer: [tex]y = -\frac{1}{4}x - 7[/tex]
That equation is in slope intercept form y = mx+b
m = -1/4 is the slope
b = -7 is the y intercept

A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.

There are a few different ways to compute the ratio of fractions. The one we used here may be a little unusual. All are equivalent.
[tex]\bullet\quad\dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}\qquad\text{"invert and multiply"}\\\\\bullet\quad\dfrac{a}{b}\div\dfrac{c}{b}=\dfrac{a}{c}\qquad\text{ratio of numerators with the same denominator}\\\\\bullet\quad\dfrac{a}{b}\div\dfrac{a}{c}=\dfrac{c}{b}\qquad\text{inverse ratio of denominators with the same numerator}[/tex]

(PLEASE HELP, BRAINLIEST IF CORRECT) A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
40 nickels
Step-by-step explanation:
1 2/5 to 2 1/3 = 7/5 : 7/3
= 21/15 : 35/15
21/15 = 24
35/15 = x
(35/15 * 24) / 21/15
∴ 56 ÷ 21/15
= 40 nickels

At the dealership where she works, Denise fulfilled 1/2 of her quarterly sales goal in January and another 5/12 of her sales goal in February. What fraction of her quarterly sales goal had Denise reached by the end of February?
Answer:
She has fulfilled about 91.6666 repeating
Step-by-step explanation:
If half of her sales were fulfilled in January, then that is 50% or 0.5. Then if you take 5/12 then it = 0.41666666, add the two decimals together and you have 0.916666 repeating. If you want to turn that into a fraction it would be 9/10 by rounding down due to the decimal.
Answer:
the answer will probably be around 1 / 12
Step-by-step explanation:

You just found the car of your dreams. It will cost $24,000. You have been saving for a car since 3rd grade and now have $6,000. Your dad will match that with another $6,000 for the car. You will pay a simple interest of 10% on the balance of what you owe after you give the car dealership the money you have between your dad and yourself.
How much money will you still owe?
Answer:
I think the answer is 13,200
Step-by-step explanation:
6k+6k=12,000 half of the price of the car
.10x12000= 10% interest = 1200 + rest of the balance(12,000)=13,200
