Answer:
The constant of proportionality is k = [tex]\frac{2}{3}[/tex] ⇒ B
Step-by-step explanation:
The form of the equation of the proportionality is y = k x, where
k is the constant of proportionality∵ Marjorie made 4 wreaths in 6 hours
→ Let y the number of wreath and x is the time of making them
∵ y = k x
∵ y = 4 and x = 6
→ Substitute them in the equation
∴ 4 = k(6)
∴ 4 = 6k
→ Divide both sides by 6 to find k
∵ [tex]\frac{4}{6}[/tex] = [tex]\frac{6k}{6}[/tex]
∴ [tex]\frac{2}{3}[/tex] = k
Let us use the other information to be sure it will give us the same value of k
∵ She made 6 wreaths in 9 hours
∴ y = 6 and x = 9
→ Substitute them in the equation
∵ 6 = k(9)
∴ 6 = 9k
→ Divide both sides by 9 to find k
∵ [tex]\frac{6}{9}[/tex] = [tex]\frac{9k}{9}[/tex]
∴ [tex]\frac{2}{3}[/tex] = k
∴ The constant of proportionality is k = [tex]\frac{2}{3}[/tex]

• On Monday the school bus traveled the Green Route 8 times and the Blue Route 9 times, traveling a total of 95 miles. • On Tuesday the school bus traveled the Green Route 12 times and the Blue Route 6 times, traveling a total of 102 miles
Answer: Green route = 5.8 miles
Blue route = 5.4 miles.
Step-by-step explanation:
Let the miles travelled for Green route be x
Let the miles travelled for Blue route be y
We can form an equation from the question given which will be:
8x + 9y = 95 ........ i
12x + 6y = 102 ......... ii
Multiply equation i by 12
Multiply equation ii by 8
96x + 108y = 1140 ....... iii
96x + 48y = 816 ....... iv
Subtract iv from iii
60y = 324
y = 324/60 = 5.4
Blue route is 5.4 miles.
Since 8x + 9y = 95
= 8x + 9(5.4) = 95
8x + 48.6 = 95
8x = 95 - 48.6
8x = 46.4
x = 46.4/8 = 5.8
Green route = 5.8 miles
The terminal side of Ø is in quadrant IV and cos Ø + 5/13, what is sin Ø?
A. -5/12
B. -12/13
C. 12/13
D. 5/12
Answer:
It’s -12/13
Step-by-step explanation:
The value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.
What is the trigonometric ratio?The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
We have:
The terminal side of Ø is in quadrant IV quadrant
cosØ = 5/13
sin²Ø = 1 - cos²Ø
sin²Ø = 1 - (5/13)²
sinØ = √(144/169)
sinØ = -12/13 (negative in IV)
Thus, the value of the sin Ø is -12/13 because sin is negative in IV option (B) is correct.

a hotel at your vacation destination quotes you a rate of $200/night. you find a similar hotel in town for 25 percent less. if you select the less expensive hotel, how much will you pay for a three-night stay?
Answer: $450
Step-by-step explanation:
Since the similar hotel in town goes for 25 percent less, that means that (100.- 25) = 75% would be paid. This will be:
= 75% × $200.
= 75/100 × $200.
= $150
The amount paid for a three-night stay will be:
= $150 × 3
= $450
Find the slope of the line : (0, 0), (3, 3)
Answer:
m=1
Step-by-step explanation:
calculate slope (m) with this formula: (y2-y1)/(x2-x1)
here are the given points: (0,0) and (3,3)
label the points
x1=0
y1=0
x2=3
y2=3
now substitute into the equation
m=(3-0)/(3-0)
m=3/3
m=1
the slope is therefore 1

Point V lies between points U and W on Line segment U W.
If UW = 9x – 9, what is UW in units?
Answer:
See Below
Step-by-step explanation:
2x - 4 + 4x + 10 = 9x - 9
6x + 6 = 9x - 9
3x = 15
x = 5
UW = 9x-9 = 9*5-9
UW = 36 units
Answer:
36
Step-by-step explanation:
UW = UV + VW
9x - 9 = 2x - 4 + 4x + 10
9x - 2x - 4x = -4 + 10 + 9
3x = 15
x = 5
UW = 9x - 9 = 9(5) - 9 = 45 - 9 = 36
