Roger wants to buy 58 tennis balls. Estimate how many canisters he would have to buy if there are 3 tennis balls per canister by rounding the total number of tennis balls to the nearest tens place.
20 canisters
Step-by-step explanation:
Long divide the 58 by 3 to get 19.3 repeating. Then round off to 20. Hope this helps!
Final answer:
After rounding 58 tennis balls to the nearest ten, Roger would need to buy approximately 20 canisters, with each canister containing 3 tennis balls.
Explanation:
Roger wants to buy 58 tennis balls and needs to estimate how many canisters he would have to buy if there are 3 tennis balls per canister. To estimate, we round the total number of tennis balls to the nearest tens place. Rounding 58 to the nearest ten gives us 60. To find the number of canisters needed, we divide the rounded number of tennis balls by the number of balls per canister:
60 ÷ 3 = 20 canisters
Therefore, Roger would need to buy approximately 20 canisters to have around 60 tennis balls.

Elle is buying new flooring for her kitchen
and laundry room. She knows that the
area of the kitchen is 132 square feet. The
laundry room is 8 1/3 feet by 6 3/4 feet. What is
the total area of the two rooms?
Answer:
The total area of the two rooms is 188.25 square feet
Step-by-step explanation:
Given:
Area of the kitchen = 132 square feet.
Dimension of the Laundry room = 8 1/3 feet by 6 3/4 feet.
To Find:
The total area of the two rooms = ?
Solution:
Area of the two rooms = Area of the kitchen + Area of the laundry room
Area of the two rooms = 132 + Area of the laundry room
Area of the laundry room =[tex](8 \frac{1}{3}) \times (6 \frac{3}{4})[/tex]
Area of the laundry room =[tex]\frac{25}{3} \times \frac{27}{4}[/tex]
Area of the laundry = [tex]\frac{675}{12}[/tex]
Area of the two rooms = [tex]132 + \frac{675}{12}[/tex]
Area of the two rooms = 132 + 56.25
Area of the two rooms = 188.25 square feet
Final answer:
The total area of Elle's kitchen and laundry room combined is 188.25 square feet. This is found by first calculating the area of the laundry room with given dimensions and then adding it to the area of the kitchen.
Explanation:
The question involves finding the total area of two rooms, given the area of one and the dimensions of the other. The kitchen has an area of 132 square feet. For the laundry room, we need to calculate the area by multiplying its length and width. The dimensions are 8 1/3 feet by 6 3/4 feet. To find the area, convert mixed numbers to improper fractions: 8 1/3 becomes 25/3 feet, and 6 3/4 becomes 27/4 feet. The area is then calculated as (25/3) * (27/4) square feet.
To compute this, multiply the numerators and denominators separately: (25*27) / (3*4) = 675 / 12, which simplifies to 56.25 square feet. Now, add the area of the laundry room to the area of the kitchen to get the total area of both rooms: 132 + 56.25 = 188.25 square feet. Therefore, the total area of the two rooms is 188.25 square feet.

Find the value of c such that the equation x^2 - c = 0 has 12 and –12 as solutions.
Answer:
c=144
Step-by-step explanation:
The given equation is [tex]x^2-c=0[/tex]
If this equation has 12 and -12 as roots, then the roots must satisfy the equation.
We substitute x=12 to obtain
[tex]12^2-c=0[/tex]
[tex]144-c=0[/tex]
Solve for c to get:
[tex]144=c[/tex]
This implies that:
[tex]c=144[/tex]
We could have also substitute x=-12 to get the same result.
Which number completes the inequality? Two-thirds less-than blank less-than StartFraction 7 over 9 EndFraction Three-fifths StartFraction 6 Over 9 EndFraction Three-fourths StartFraction 6 Over 7 EndFraction
Answer:
c
Step-by-step explanation:
Final answer:
To complete the inequality, we convert the fractions to decimal form or find a common denominator to compare them. The number that completes the inequality is three-fourths (0.75), as it is larger than two-thirds but smaller than seven-ninths.
Explanation:
The student is asking which number fulfills the inequality between two-thirds and various other fractions. To determine the correct number that completes the inequality, we should consider the values of the fractions in decimal form or by comparing them to each other after finding a common denominator.
For example, two-thirds is approximately 0.666..., three-fifths is 0.6, seven-ninths is approximately 0.777..., three-fourths is 0.75, and six over nine is equivalent to two-thirds (as six-ninth simplifies to two-thirds).
Considering these values, the number that fills the gap should be bigger than two-thirds and smaller than the smallest fraction among the given options that is bigger than two-thirds. Therefore, three-fourths (0.75) fits the inequality because it is larger than two-thirds (approximately 0.666...) but less than seven-ninths (approximately 0.777...).

The path of a football kicked by a field goal kicker can be modeled by the equation y = –0.04x2 + 1.56x, where x is the horizontal distance in yards and y is the corresponding height in yards. What is the approximate maximum height of the football?
The maximum height of the football is approximately 15.21 yards.
Explanation:The given equation for the path of the football is y = –0.04x^2 + 1.56x, where x is the horizontal distance in yards and y is the corresponding height in yards. To find the maximum height of the football, we need to determine the vertex of the parabolic function represented by the equation. The vertex represents the point where the function reaches its maximum or minimum value.
The vertex of a quadratic function in the form y = ax^2 + bx + c can be found using the formula x = -b/(2a). In this case, a = -0.04 and b = 1.56. Plugging these values into the formula, x = -1.56/(2*-0.04) = 19.5. Substituting this value back into the equation, we can find the corresponding y value which represents the maximum height of the football.
y = –0.04(19.5)^2 + 1.56(19.5) = -0.04(380.25) + 30.24 = 15.21 yards
Anton's family drove 216 mi to the lake averaging 48 mi/h . On the return trip home they averaged 54 mi/h .
What was the total time that Anton's family spent driving to and from the lake?
The total time that Anton's family spent driving to and from the lake is 8.5 hours
Solution:
Time taken is given by formula:
[tex]Time = \frac{distance}{speed}[/tex]
Anton's family drove 216 mi to the lake averaging 48 mi/h
⇒ Anton's family drove total distance = 216 mi les
⇒ Speed of Antony's family driving to lake = 48 miles per hour
[tex]Time = \frac{216}{48} = 4.5[/tex]
Therefore, time taken to drive to lake is 4.5 hour
On the return trip home they averaged 54 mi/h
[tex]Time = \frac{216}{54} = 4[/tex]
Therefore, time taken to return home is 4 hours
Total time = 4.5 + 4 = 8.5 hours
Thus the total time that Anton's family spent driving to and from the lake is 8.5 hours
what is the probability of rolling a dice at most 3 times until a 6 occurs
Answer:
Probablity of getting six in at most three roll= 0.199.
Step-by-step explanation:
Given: Dice rolled at most 3 times untill a 6 occurs.
First, finding the probablity of getting 6 in a dice if rolled once.
Probablity= [tex]\frac{chances\ of\ occurance}{Total\ number\ of\ event}[/tex]
We know, dice have six side, therefore, total number of event will be 6.
∴ Probablity of getting six in one roll= [tex]\frac{1}{6}[/tex]
As given, Dice is rolled at most 3 times.
Now, finding the probablity of getting 6 in a dice if rolled 3 times.
∴ Probablity of getting six in three roll= [tex]\frac{1}{6}+(\frac{1}{6})^{2} +(\frac{1}{6})^{3}[/tex]
⇒ Probablity of getting six in three roll= [tex]\frac{1}{6}+\frac{1}{36} +\frac{1}{216}[/tex]
Taking LCD 216
⇒Probablity of getting six in three roll= [tex]\frac{1\times 36+ 6\times 1+1}{216}[/tex]
⇒Probablity of getting six in three roll= [tex]\frac{43}{216}[/tex]
∴Probablity of getting six in three roll=0.199
