What number should be placed in the box to help complete the division calculation?
Answer:12
Step-by-step explanation:
A rettangle is 10 inches smaller than it is wide. The perimeter of the
rectangle is 80 inches. Find the length and width of the rectangle.
a. Width = 25 Length = 15
b. Width = 30 Length = 20
c. Width = 25 Length = 35
d. Width = 20 Length = 30
e.Width = 15 Length = 25
f. Width = 35 Length = 25
Answer:
A. Width = 25 Length = 15
Step-by-step explanation:
Length = L = Width - 10
Width = W
Perimeter of a rectangle
=> 2 (L + B) = 80
=> 2 (W - 10 + W) = 80
=> 2 (2W - 10) = 80
=> 4W -20 = 80
=> 4W -20 + 20 = 80 + 20
=> 4W = 100
=> 4W/4 = 100/4
=> W = 25
Width = 25
Length = 25 - 10 = 15
So, the answer is A.

A runner gets a 30.0 meter head start then runs 5.0km/hr. Write an equation which will represent the runners distance from the start line at any second
Answer:
d = 1.4 t + 30
Step-by-step explanation:
Head start means any advantage achieved or advantage gained in any race or competition.
In the context, the runner is gained a head start of 30 meter from the starting point.
It is also given that the speed with which the runner is running is 5.0 km per hour.
Therefore, the equation that gives the distance covered by the runner from his start line at any time in seconds is given by d = 1.4 t + 30.
Convert the following to scientific notation: 5050
Answer:
5.05*10³
Step-by-step explanation:
Put the decimal after the first digit and drop the zeroes. To find the exponent count the number of places from the decimal to the end of the number.5050 = 5.05 *1000 = 5.05*10³Daredevil Danny was cliff jumping. He jumped off a cliff that was 1 4 . 2 14.214, point, 2 meters above the surface of the water. At the end of his jump, Danny was 2 . 3 2.32, point, 3 meters below the surface of the water.
Question:
Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the water. At the end of his jump, Danny was 2.3 meters below the surface of the water.
The following equation describes this situation 14.2 + (-16,5) = -2.3 .
What does -16.5 tell us?
Answer:
The displacement between his current position and his initial position
Step-by-step explanation:
Given
[tex]Initial\ Position = 14.2m[/tex]
[tex]Final\ Position = -2.3m[/tex]
[tex]14.2 + (-16.5) = -2.3[/tex]
Required
What does -16.5 represents?
To understand this, we need to first calculate the displacement between his initial and final position
[tex]Displacement = Final\ Position - Initial\ Position[/tex]
[tex]Displacement = -2.3m - 14.2m[/tex]
[tex]Displacement = - 16.5m[/tex]
So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)
During a fourth of July celebration, a cannon is fired upwards from Fort Ontario. The height, h, in feet, of the cannonball above sea level at any given time, t, in seconds, can be determined by the formula h = -16t2 + 120t + 200. Find the height, in feet, of the cannonball above sea level 5 seconds after the cannon is fired.
Answer:
400 feet
Step-by-step explanation:
We just need to find h when t = 5. To do so, we can plug t = 5 into the function, which would be:
h = -16t² + 120t + 200
= -16 * 5² + 120 * 5 + 200
= -400 + 600 + 200 = 400 feet
Answer:
h = 400 feet
Step-by-step explanation:
given t = 5 seconds
h = -16t² + 120t + 200
just substitute t = 5
h = -16(5)² + 120(5) + 200
h = 400 feet
Tony rounded each of the numbers 154 and 145 to the nearest hundred. Which choice correctly compares the rounded numbers!
150 = 150
200 > 100
0154 > 145
200 = 200
Answer:
200 > 100
Step-by-step explanation:
154 rounded to the nearest hundred is 200 because 154 is closer to 200 than to 100. and 145 is closer to 100 than it is to 200 so we have 200 and 100 and we know that 200 is greater than 100 so we can conclude with 200 > 100
Find the area of the triangle below
Answer:
[tex]A=73.5\text{ cm}^2[/tex]
Step-by-step explanation:
The formula for an area of a triangle is:
[tex]A=\frac{1}{2}bh[/tex]
Where b is the base length and h is the vertical height.
From the triangle, we can see that the base is 21 cm while the vertical height is 7. Thus:
[tex]A=\frac{1}{2}(7)(21)[/tex]
Multiply:
[tex]A=\frac{1}{2}(147)[/tex]
Multiply:
[tex]A=73.5\text{ cm}^2[/tex]
And that's our answer :)
The Area of triangle is 73.5 square cm.
We have from the figure,
Base of triangle = 21 cm
Height of triangle = 7 cm
side of triangle = 15 cm
We know the formula for Area of Triangle
Area of Triangle = 1/2 x base x height
Now, plugging the value of base and height in the formula we get
Area of triangle = 1/2 x base x height
= 1/2 x 21 x 7
= 147/2
= 73.5 square cm

A bag contains 8 red marbles, 7 blue marbles and 5 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that both marbles drawn will be green?
Answer:
Probability that both marbles drawn will be green = 1 / 20
Step-by-step explanation:
(It is assumed that marbles are not returned in the bag)
[tex]p(1st \: marble \: drawn \: is \: green) = \frac{5}{20} [/tex]
[tex]p(2nd \: marble \: drawn \: is \: green) = \frac{4}{20} [/tex]

[tex](-7,4]\text{ or }\{x|-7<x\leq 4\}[/tex]
Step-by-step explanation:
The domain is the span of x-values covered by the function.
From the graph, we can see that the graph covers all the x-values from x=-7 to x=4.
However, note that closed and open circles. There is an open circle at x=-7, which means that the domain excludes x=-7. However, the circle at x=4 is closed, meaning it is included in the domain.
Therefore, the domain is, in interval notation:
[tex](-7,4][/tex]
We use parentheses on the left because we do not include -7. And we use brackets on the right because we do include the 4.

Hi there! Hopefully this helps!

5(0.3) + 2y = 20
Answer: Y = 9.25.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| 5(0.3) + 2y = 20
| Multiply 5 and 0.3 to get 1.5
\/
1.5 + 2y = 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We subtract 1.5 from both sides.
2y = 20 - 1.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Subtract 1.5 from 20 to get 18.5.
2y = 18.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Divide both sides by 2.
[tex]y = \frac{18.5}{2}[/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Expand [tex]\frac{18.5}{2}[/tex] = 9.25 by multiplying both numerator and the denominator by 10.
[tex]y =\frac{185}{20}[/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Reduce the fraction [tex]\frac{185}{20} = 9.25[/tex] to lowest terms by extracting and canceling out 5.
[tex]y =\frac{37}{4}[/tex].
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[tex]\frac{37}{4} = 9.25[/tex] in decimal form.

The probability of spinning an even number on a spinner is 0.4. What is the probability of not spinning an even number, expressed as a percent?
Answer:
60%
Step-by-step explanation:
There are only even and odd numbers. If a number is not even, it is odd. If the probability of spinning an even number is 0.4, or 40%, then just subtract that by the whole spinner, which is equivalent to 100%:
100% - 40%
= 60%
This means that the odds of spinning an odd number is 60%

Answer:
0.37 feet.
Step-by-step explanation:
The following data were obtained from the question:
Volume (V) = 4100 ft³
Height (h) = 1.8 miles
Radius (r) =?
Next, we shall convert 1.8 miles to foot.
This can be obtained as follow:
Recall:
1 mile = 5280 ft
Therefore,
1.8 miles = 1.8 × 5280 = 9504 ft
Finally, we determine the radius as follow:
Volume (V) = 4100 ft³
Height (h) = 9504 ft
Pi (π) = 3.14
Radius (r) =?
V = πr²h
4100 = 3.14 × r² × 9504
4100 = r² × 29842.56
Divide both side by 29842.56
r² = 4100/29842.56
Take the square root of both side
r = √(4100/29842.56)
r = 0.37 ft
Therefore, the radius of the hole is 0.37 feet.
