How much change will you get back from a quarter if you buy 2 ten-cent candies?
A. 1 dime
B. 1 nickel and 2 pennies
C. 2 dimes
D. 2 nickels
E, 1 nickel
Answer:
E. 1 nickel
Step-by-step explanation:
2 ten cent= 20 cent
a quarter is 25 cent
25-20=5
a nickel is 5 cent
Answer:
E.) nickle (5 cents)
Step-by-step explanation:
You give 25 cents (value of a quarter)
2 ten-cent candies is equal to 20 cents:
[tex]2*10=20\\10+10=20[/tex]
Find the difference between what you paid and the actual amount:
[tex]25-20=5[/tex]
You paid an extra 5 cents. Find the answer that has the same value as 5 cents:
A. ) 1 dime
This is wrong because a dime is worth 10 cents, not 5
B.) 1 nickel 2 pennies
this is wrong because a nickle is worth 5 cents and a penny is worthy 1 cent. Add the values, and the change would be 7 cents.
C.) 2 dimes
This is wrong because a dime is worth 10 cents, so 2 dimes would be 20 cents.
D.) 2 nickles
This is wrong because a nickle is worth 5 cents, so 2 nickles would be 10 cents.
E.) 1 nickle
This is correct because a nickle is worth 5 cents, the exact change you should receive.

Candice wants to estimate the proportion of the freshmen at her high school that likes sports drinks. She interviews a simple random sample of 75 of the 215 freshmen on campus. She finds that 18 students like sports drinks. Is the Normal condition for finding confidence intervals met? Explain.
Yes, the Normal condition for finding confidence intervals is met because np = 18 and n(1 − p) = 57, both of which are greater than 10.
The following information should be considered:
Since there is the simple random sample of 75 of the 215 freshmen on campus. She finds that 18 students like sports drinks.So, it is the normal condition as np = 18 and n (1- p) = 57.Learn more: https://brainly.com/question/1504221?referrer=searchResults
The Normal condition for constructing confidence intervals is met if both np and n(1-p) are greater than 10. In Candice's case, both conditions are met, so she can proceed with constructing a confidence interval for the proportion of freshmen who like sports drinks.
In order to determine if the Normal condition for constructing confidence intervals is met, we need to check if both np and [tex]\( n(1-p)[/tex] are greater than 10. Here n is the sample size and p is the sample proportion.
For Candice's sample:
n = 75 (sample size)p (sample proportion) = [tex]\frac{18}{75} = 0.24[/tex]Now, calculate np and n(1-p):
[tex]\[ np = 75 \times 0.24 = 18 \][/tex][tex]\[ n(1-p) = 75 \times (1 - 0.24) = 75 \times 0.76 = 57 \][/tex]Both values (18 and 57) are greater than 10, so the Normal condition is met. Therefore, it is appropriate to proceed with constructing a confidence interval for the proportion of freshmen who like sports drinks.

The radius of a circle is 13 feet. What is the length of an arc that subtends an angle of
radians?
13 ft
Give the exact answer in simplest form.
feet
Answer:
The length of the arc is 221π/18 ft or 38.55 ft
Step-by-step explanation:
Given
Subtended angle, θ = 17π/18
Radius, r = 13 ft
Required
Length of the arc.
When an angle is given in radians, the length of the arc is calculated using the formula below
Length = rθ
By substituting
Length = 13 * 17π/18
Length = 221π/18
The answer can be left in this form.
But for simplification purpose, I'll solve further.
Taking π as 3.14
Length = 221 * 3.14/18
Length = 693.94/18
Length = 38.552222
Length = 38.55 ft (Approximated).
Hence, the length of the arc is 221π/18 ft or 38.55 ft

The rate of collection by a solar panel decreased steadily throughout the day due to increasing cloud cover until it reached a constant amount. Later in the day, there were two short periods where the Sun appeared, only for the cloud cover to return.
Which graph models the amount of energy collected depending on the time since the cloud cover began?
ANSWER: B
Answer:
Second graph
Step-by-step explanation:
In the second graph we can see how the rate of collection decreases steadily at 0 < x < 7.5; at x = 7.5 it becomes constant; and later in the day, there were two short periods (about x = 12.5 and x = 22.5) where the rate of collection has two peaks.

A passenger car travels 16 mph faster than the commuter bus. If the bus travels 56 miles in the same time it takes the car to travel 84 miles, what is the speed of each vehicle?
Answer:
speed of commuter bus: 32 km
speed of passenger car : 48 mph
Step-by-step explanation:
We will use the concept of speed distance and time.
where time = distance / speed
____________________________________________________
Let the speed of commuter bus be x mph
Given that passenger car travels 16 mph faster than commuter bus.
Speed of passenger car if speed of commuter bus is x mph (x+16)mph
Distance traveled by commuter bus = 56 miles
Time taken by commuter bus to travel 56 miles = 56/X (1)
Distance traveled by passenger car = 84 miles
Time taken by passenger car to travel 84 miles = 84/(X+16) (2)
__________________________________________
It is given that time taken by both bus and car is same
so equating equation 1 and 2
we have
56/X = 84/(X+16) (by cross multiplication we have)
=> 56(X+16) = 84*X
=> 56X + 896 = 84X
=> 896 = 84X - 56 X
=> 896 = 28X
=> X = 896/28 = 32.
Therefore , speed of commuter bus is x mph or 32 km
speed of passenger car is x+16 mph = (32+16) mph = 48 mph
Final answer:
The passenger car travels at 48 mph, while the commuter bus travels at 32 mph, derived from the fact that they travel the same time but different distances.
Explanation:
To find the speeds of the passenger car and the commuter bus, we can use the formula for distance (distance = speed × time). Since both the bus and the car travel for the same amount of time, we can set up an equation to solve for their speeds based on the distances they travel.
Let x be the speed of the commuter bus in mph. Consequently, the speed of the passenger car would be x + 16 mph. According to the information given:
The bus travels 56 miles.
The car travels 84 miles.
Since they travel for the same time t, we have:
Bus: 56 miles = x × t
Car: 84 miles = (x + 16 mph) × t
Dividing the mileage of the car by the bus gives us:
[tex]\(\frac{84}{56} = \frac{(x + 16)t}{xt}\)[/tex]
[tex]\(1.5 = \frac{x + 16}{x}\)[/tex]
Multiplying by x to get rid of the fraction and then solving for x provides:
1.5x = x + 16
0.5x = 16
x = 32 mph
This means the bus travels at 32 mph and the passenger car travels at:
32 mph + 16 mph = 48 mph
Therefore, the speed of the passenger car is 48 mph and the speed of the commuter bus is 32 mph.

A rectangle has a height of 5 and a width of 4x^2-2x-6 . Express the area of the entire rectangle.
Answer:
20x² - 10x - 30
Step-by-step explanation:
Height = 5
Width = 4x² - 2x - 6
Area of rectangle = length × breadth
Area of triangle = height × width
Area = 5 × (4x² - 2x - 6)
Area = 20x² - 10x - 30
Area of the rectangle is 20x² - 10x - 30
