Answer:
y = 83.33 cm
Step-by-step explanation:
Relation between the rise in water level (h) and duration (t) to fill the water in the garden hose is proportional.
h ∝ t
h = kt
Here, k = Proportionality constant
If the rise in the water level of the hose = 13 cm
Time to fill the water up to 13 cm = 3 minutes
13 = 3k
k = [tex]\frac{13}{3}[/tex] cm per minute
Therefore, equation will be,
h = [tex]\frac{13}{3}t[/tex]
If a data point (19, y) lies on the graph,
y = [tex]\frac{13\times 19}{3}[/tex]
y = 82.33 cm
Therefore, y = 82.33 cm is the answer.
When Sergio went to dinner with his brother, the bill was $51.19. What was the total they paid if they left a 15% tip?
Answer:
The total they paid was $58.8685
Step-by-step explanation:
Let us solve the question using the percentage method
∵ Sergio went to dinner with his brother
∵ The bill was $51.19
∵ They left a 15% tip
→ That means they pay extra money 15% of $51.19
∴ The total they paid = the bill + 15% of the bill
∵ 15% of the bill = 15% × 51.19
→ Change 15% to a decimal by divide it by 100
∴ 15% of the bill = [tex]\frac{15}{100}[/tex] × 51.19
∴ 15% of the bill = 0.15 × 51.19
∴ 15% of the bill = $7.6785
→ Substitute it in the total they paid
∵ The total they paid = 51.19 + 7.6785
∴ The total they paid = $58.8685
∴ The total they paid was $58.8685

7n-(m+18)
if n = 4; m=10 how do you solve ?
Answer:
7(4) - (10+18)
28 - 28
0
Step-by-step explanation:
Step-by-step explanation:
okay, 7 (n) if n = 4 that means 7 times 4 so that equals 28 BUT we do (m + 18) first so if m= 10 that means (10 + 18) would be 28, so
28 - 28= 0

Olive is going to buy a scooter that costs $95. The sales tax rate is 8.5%. What is the total cost of the scooter including tax to the nearest cent?
Answer:
$103.08
Step-by-step explanation:
The total cost of the scooter including tax to the nearest cent will be $103.08.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Olive is going to buy a scooter that costs $95. The sales tax rate is 8.5%.
The amount of the sales tax will be
Sale tax = 8.5% of $95
Sale tax = 0.085 × $95
Sale tax = $8.075
The total cost of the scooter including tax to the nearest cent will be
Total cost = $95 + $8.075
Total cost = $103.075 ≈ $103.08
The total cost of the scooter including tax to the nearest cent will be $103.08.

What is the slope and equation of a line parallel to the y-axis passing through point (9, -1)?
O A. The slope is zero and the equation of the line is y=-1.
O B. The slope is undefined and the equation of the line is y = -1.
O C. The slope is undefined and the equation of the line is x = 9.
D. The slope is zero and the equation of the line is x
Answer:
The slope is undefined and the equation of the line is x = 9 ⇒ C
Step-by-step explanation:
Parallel lines have the same slopes and different y-interceptsThe slope of any vertical line is undefinedThe equation of any vertical line is x = a, where a is the x-coordinate of a point that lies on the lineAll x-coordinates of the points lie on a vertical line equalLet us solve the question
∵ The line is parallel to the y-axis
∵ The y-axis is a vertical line
→ By using the second note above
∴ The slope of the y-axis is undefined
→ By using the first note above
∴ The slope of the line is undefined
→ By using the third note above
∵ The equation of the vertical line is x = a
∵ a is the x-coordinate of a point on the line
∵ The line passes through the point (9, -1)
∴ a = 9
∴ The equation of the line is x = 9

(-4,6), slope=-1
Write the slope-intercept equation using the given information.
Answer:
y = -x +2
Step-by-step explanation:
y = mx + b
y=6
x=-4
m=-1 (m is the slope)
b=? (b is the y-intercept)
Putting these numbers into this equation,
6 = -1(-4) + b
b=6-4
b=2
So the equation is y = -1x + 2
or just y = -x +2

There are 90 calories in a 3/4 cup serving of cereal.
How many calories are in 1 cup?
How many calories are in 6 cups?
90
3/4
=1
=6
Answer:
120 calories in 1 cup, 720 in 6 cups
Step-by-step explanation:
I divided 90 by 3 to get 1/4 cup and then multiplied it by 4 to get for one cup. From there I multiplied by 6
Answer:
1 cup=120 calories 6 cups=720 calories
Step-by-step explanation:
We know that there are 90 calories in 3/4 of a cup and we can figure out that 30 calories are in each 1/4 of a cup because 90 divided by 3 equals 30 then just add 30 calories to 90 and get 120. Finally just do 120 times 6 and get 720 .
