Answer:
4.25 hours
Step-by-step explanation:
A fully charged phone would be at 100%, so we'll set y equal to 100 and solve for x:
100=20x+15
85=20x
4.25=x
So Sammi's phone will be fully charged in 4.25 hours.
Answer:
4.25 hours
Step-by-step explanation:
"Fully charged" means the percentage should be 100%.
Substitute 100 for y then solve for x.
[tex]100=20x+15\\85=20x\\x=\frac{85}{20}\\x=4.25 \text{ hours}[/tex]

In the table given in the question 0.2 means that 20% of her customers ordered an appetizer but not a dessert.
What is two way table?Two way table is a table which shows the frequencies or relative frequencies of some values in the data.
How to find frequency?From the table it is given that:
0.1=10% of the customers ordered both an appetizer and a dessert.0.3=30% of the customers ordered a dessert but not an appetizer.0.4=40% of the customers ordered a dessert.0.2=20% of the customers ordered an appetizer but not a dessert.0.4=40% of the customers neither ordered appetizer nor dessert.0.3=30% of the customers ordered an appetizer.0.7=70% of the customers did not order an appetizer.The total is of 100%.

An engineer is designing a fountain that shoots out drops of water. The nozzle from which the water is launched is 3 meters above the ground. It shoots out a drop of water at a vertical velocity of 14 meters per second. Function h models the height in meters, h, of a drop of water t seconds after it is shot out from the nozzle. The function is defined by the equation h(t)=−5t2+14t+3. How many seconds until the drop of water hits the ground?
Answers
Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -5t^2 + 14t + 3[/tex]
Required
Time the drop will hit the ground
When the drop hits the ground,
[tex]h(t) = 0[/tex]
So, we have:
[tex]0 = -5t^2 + 14t + 3[/tex]
Rewrite as:
[tex]5t^2 - 14t - 3 = 0[/tex]
Expand
[tex]5t^2 + t - 15t - 3 = 0[/tex]
Factorize
[tex]t(5t + 1) -3(5t + 1) = 0[/tex]
Factor out 5t + 1
[tex](t -3)(5t + 1) = 0[/tex]
Split
[tex]t -3 = 0[/tex] or [tex]5t + 1 = 0[/tex]
Solve for t
[tex]t = 3[/tex] or [tex]5t = -1[/tex]
Time cannot be negative.
So:
[tex]t = 3[/tex]

Casho has a bag that contains pineapple chews, lemon chews, and lime chews. She performs an experiment. Casho randomly removes a chew from the bag, records the result, and returns the chew to the bag. Casho performs the experiment 54 times. The results are shown below:
A pineapple chew was selected 9 times.
A lemon chew was selected 15 times.
A lime chew was selected 30 times.
Based on these results, express the probability that the next chew Casho removes from the bag will be pineapple chew as a percent to the nearest whole number.
Answers
Answer:
17% the next chew Casho pulls out is pineapple
Step-by-step explanation:
pineapple chew 9/54
lemon chew 15/54
lime chew 30/54

375.66 cm²
Step-by-step explanation:
The two semicircles add to a full circle.
For the circle, d = 18 cm.
r = d/2 = 9 cm.
A = LW - πr²
A = (35 cm)(18 cm) - 3.14(9 cm)²

A package is shaped like a right rectangular prism. Use the dimensions shown to find the surface area of this package.
A)6 square feet
B)12 square feet
C)20 square feet
D)22 square feet
Answers
Answer:
The surface area is 22 square feet
Step-by-step explanation:
For a right rectangular prism, we have the formula for the area as;
A = 2(lb + lh + bh)
Accordingly, we have l as the length, b as the breadth and h as the height
Using the given dimensions, we have
A = 2(3(1) + 3(2) + 1(2))
A = 2(3 + 6 + 2)
A = 2(11) = 22 square feet

x = 9
Step-by-step explanation:
The top shape's side values are 3 times larger than the side values of the bottom shape, so x + 15 = 3(8).
Solve for x and you get x = 9.
Answer:
x = 9
Step-by-step explanation:
9 / x = 3 -> x = 3
(x+15) / 3 = 8
x + 15 = 8*3
x+15 = 24
x = 24 - 15
x = 9

Solution given:
area of a circle[A]=πr²
circumference of circle [C]=2πr
when circumference of circle is doubled
it becomes :4πr
Step-by-step explanation:
area directly proportional to circumference
πr²=2πr
when circumference is doubled
πr²=2(2πr)
so area
C. The area is 2 times the original circle
