Find the area, to the nearest hundredth, of the figure
Answer:
Step-by-step explanation:
hypotenuse = √(14.4² + 6²) = √243.36 = 15.6 mi
area of triangle = 0.5×6×14.4 = 43.2 mi²
radius of semicircle = 15.6/2 = 7.8
area of semicircle = πr² = 60.84π mi²
total area = 43.2 + 60.84π ≅ 234.33 mi²
Round 43.827 to the nearest hundredth.
Answer:
43.83
Step-by-step explanation:
if the 3rd digit to the right of the decimal (the hundredths place) is higher than 4 you round the 2nd digit to the right of the decimal (the tenths place ) up by 1 number and if the 3rd digit to the right of the decimal (the hundredths place ) is less than 4 you round the 2nd digit to the right of the decimal (the tenths place) down by 1.
Answer:
43.83
Step-by-step explanation:
be cause the 7 is bigger than 2 and you make the 2 into 3.
The denominator of a basketball is approximately 9 inches. what is the volume?
Answer: v=43πr3 where r is the radius. You have the diameter, that is the double of the radius, so r=92=4.5 inches. v=43π4.53=381.69 cubic inches.
Answer:
381.7
Step-by-step explanation:
to get the volume of a sphere the formula is:
V=4 /3πr3
(remember basketball isn't a circle because it is 3-d)
you plug in the radius to that formula and boom you got your answer!
(remember radius is half the diameter, and half of 9 is 4.5)
so your answer would be:
381.7

If Simone needs to buy at least 18 pies and has no more than $110 to spend, what is the maximum number of cherry pies she can buy?
Answer:
the answer is 15
Step-by-step explanation:
because 110÷7$
The maximum number of 15 cherry pies she can buy.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
Simone is buying pies for a party.
One cherry pie costs $7,
and one apple pie costs $5.
If Simone needs to buy at least 18 pies and has no more than $110 to spend,
the maximum number of cherry pies,
= 110/7
= 15.71.
If 15 cherry pies, then 3 apple pies.
The total amount = 15 x 7 + 3 x 5
= 110
Therefore, 15 is the maximum number.

A truck driver can travel 200 miles in 3 days.
At that rate, how far will he travel in 12 days?
Answer: the answer is 6000
Step-by-step explanation:
The division is one of the four fundamental arithmetic operations. The distance travelled by the driver in 12 days is 800 miles.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
A truck driver can travel 200 miles in 3 days. Therefore, the distance which the truck can travel in one day is,
Distance in a day = 200miles/3day = 66.6667 miles/day
The distance that the truck can travel in 12 days are,
Distance = 66.6667miles/day ×12 day = 800 miles
Hence, the distance travelled by the driver in 12 days is 800 miles.

If ADEF is reflected over the x-axis, what would be the coordinates of point F?
Answer:
Please check the explanation.
Step-by-step explanation:
Let the coordinates of the point F be (x, y).
When a point F(x, y) is reflected over the x-axis, the x-coordinate of the point F remains the same, and the y-coordinate of the point reverses the sign.
Thus, the rule of reflection over the x-axis:
F(x, y) → F'(x, -y)
Here,
F'(x, -y) would be coordinates of point F after the reflection over the x-axis.
Let say, the point F(1, 2).
The coordinate of the point F after the reflection over the x-axis would be:
F(1, 2) → F'(1, -2)
Thus, F'(1, -2) would be the coordinates of point F after the reflection over the x-axis.

because She should have distributed the -2 inside the parentheses.
the process should be like this;

17(1-x)<13
17-17x<13
-17x<13-17 (17 goes to the opposite side as -17)
-17x<-4 (we divide each side by 17)

A roller 2 m long has a diameter 140 cm. To level a play ground it takes 350 complete revolutions. Determine the cost of levelling the playground at the rate of
75 paise per square meter.
Diameter of a roller = 140 cm
Radius of the roller :
[tex] =\tt \frac{diameter}{2} [/tex]
[tex] =\tt \frac{140}{2} [/tex]
[tex] = \tt70 \: cm[/tex]
Thus, the radius of the roller = 70 cm
Height of roller = 2 m = 2×100 cm = 200 cm
Curved surface area of roller = 1 revolution
The curved surface area of this roller :
[tex] =\tt 2\pi rh[/tex]
[tex] = \tt2 \times 3.14 \times 70 \times 200[/tex]
[tex] =\tt87920 \: {cm}^{2} [/tex]
Thus, the curved surface area of the roller = 87920 cm²
Number of revolutions that needs to be done to level the ground = 350
Distance the roller will travel to get leveled :
[tex] =\tt 87920 \times 350[/tex]
[tex] = \tt43960000 \: cm[/tex]
[tex] = \tt \frac{43960000}{100} \: m[/tex]
[tex] = \tt439600 \: m[/tex]
Thus, to level the playground the distance the roller should cover = 539600 m
Cost of covering one square meter of land = 75 Paise
Cost of covering 539600 m of land :
[tex] =\tt 539600 \times \frac{75}{100} \: Rs[/tex]
[tex] = \tt \frac{539600 \times 75}{100} \: Rs[/tex]
[tex] =\tt \frac{40470000}{100} \: Rs[/tex]
[tex]\color{plum} = \tt\bold{404700 \: rupees}[/tex]
Therefore :▪︎The cost of leveling the playground = 404700 Rs

The Miller Family shares a cell phone plan. Last month, Jodie used 3/4 of the minutes. Her son Billy used 4/5 of the remaining minutes. What fraction of the minutes did Billy use?
Answer: The fraction of the minutes did Billy use = [tex]\dfrac15[/tex].
Step-by-step explanation:
Let x = Total minutes given in the plan.
Last month, Jodie used [tex]\dfrac34[/tex] of the minutes.
Remaining minutes = [tex]x-\dfrac34x=\dfrac14x[/tex]
Billy used = [tex]\dfrac45(\dfrac14x)=\dfrac{x}{5}[/tex] minutes
Fraction of the minutes used by Billy = [tex]\dfrac{\dfrac{x}{5}}{x}=\dfrac15[/tex]
Hence, the fraction of the minutes did Billy use = [tex]\dfrac15[/tex].

Step-by-step explanation:
The slope is 2/1, or 2x because the height between any two given intercepting points is two times higher than it is far.
Take for example the intercepting points at (6, 1) and (7, 3). Since slope is rise/run, the slope has risen 2 and 'run' 1. This makes the slope 2/1.

How is adding and subtracting rational numbers similar and different than adding and subtracting integers?
Answer and explanation:
A rational number is a number that can expressed as fraction where the demoninator of the fraction is not zero, example 2/3, 5/1, 4/6 etc
An integer is a whole number, negative or positive example - 2, 3, -4, 1 etc
Adding and subtracting integers and rational numbers are not very much different. Most numbers are rational numbers anyway. When adding rational numbers 1/2+3/1 for instance, we simply add them like normal fractions:
1/2+3/1= 1+6/2=7/2=2 1/2
When adding intergers 2+4, we add normally as in the number line = 6
