There are 24 hours in a day and so 15 hours is 15÷24=58 of a day. Since the rig drills 60 feet underground in a day, in 58 of a day it will drill
(58 days)×(60feetday)=3008 feet.
So the rig will have drilled 3008=37.5 feet underground in 15 hours.
The rig drills 60 feet underground per day so to find how long it has been running to go 143.6 feet underground, we need to calculate
(143.6 feet)÷(60feetday)=143.660 days.
This is about 2.4 days. Alternatively, it is 57.44 hours
We know that the rig drills at a constant rate, so there is a proportional relationship between the two quantities d, the height to which the drill has dug, and t, the number of days the drill runs. It drills at -60 feet per day, so we can represent this relationship with the equation:
–60t=d
Since 15 hours is 1524=58 days, we can use the equation to find d:
–60⋅58=d
Since the depth is the same whether we think of it as a positive depth below the surface or a negative height above the surface, we can find this value by multiplying 60⋅58=37.5 and then noting that the sign must be negative if we are representing positions below the surface of the earth by negative numbers. So d=–37.5 and the drill will be at height -37.5 feet after 15 hours.
Likewise, if we know the drill has dug to -143.6 feet, we can use the equation again, this time to find t:
−60t=−143.6
so t=(−143.6)÷(−60). Since the amount of time would be the same if we were working with positive feet below the surface of the earth and a drill rate of 60 feet per day below the earth surface, we can find this value by dividing 143.6÷60, which is about 2.4 days.
Jen is investigating a quadratic function g(x). She writes four different forms of the function, as shown below. Select the form that reveals the maximum value of g(x) without having to be rewritten.
Answer:
A
Step-by-step explanation:
Since the coefficient of the x² term is negative (we know this because if you look at C, the coefficient of x² is -2, which is negative) we know that the vertex will be the maximum. To find the vertex without having to be rewritten, a quadratic function should be written in vertex form which is y = a(x - c)² + d where (c, d) is the vertex. The answer choice that is written in vertex form is A.
help pls!!!how to solve it
Answer:
q = 5/6
Step-by-step explanation:
First, we distribute.
16q - 10 = 4q
Then, we combine like terms.
-10 = 4q - 16q
-10 = -12q
Finally, we divide -12 on both sides.
5/6 = q, or q = 5/6
Hope this helps ^^
Find the distance between each pair of points. Round to the tenths place.
Answer:
12.0
Step-by-step explanation:
Given the two points shown on the graph above, assuming 1 unit = 1 box, the coordinates of the two points are: (2, 7) and (-6, -2)
Use the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_2)^2} [/tex], to find the distance between points (2, 7) and (-6, -2)
Let,
[tex] (2, 7) = (x_1, y_1) [/tex]
[tex] (-6, -2) = (x_2, y_2) [/tex]
[tex] d = \sqrt{(-6 - 2)^2 + (-2 - 7)^2} [/tex]
[tex] d = \sqrt{(-8)^2 + (-9)^2} [/tex]
[tex] d = \sqrt{64 + 81} = \sqrt{145} = 12.0 units [/tex] (nearest tenth)

a metal block has the following dimensions height 2cm length 10cm width 5cm calculate the volume of the block
Answer:
100cm^3
Step-by-step explanation:
The volume of any cube or cuboid is calculate by simply multiplying the length by the width by the height.
So if our length is 10cm, our width is 5cm and our height is 2cm, then our volume is 10x5x2=100cm^3 (cubic centimeters-unit for volume.)

Kaya rented a limousine for prom. The company charges a cleaning fee of $100 and an hourly rate of $45. Her total cost for the night was $437.50. For how many hours did Kaya rent the limousine?
Answer:
Number of hours= 7.5
Step-by-step explanation:
Giving the following information:
The company charges a cleaning fee of $100 and an hourly rate of $45.
Her total cost for the night was $437.50
First, we need to structure the total cost formula:
Total cost= 100 + 45*x
x= number of hours
437.5= 100 + 45x
337.5/45= x
x= 7.5
Number of hours= 7.5
Answer:
Kaya rented the limo for about 7.5 hours
Hope this helps! good luck :)

can a pentagon be a cross section of a triangular prism?
Answer:
No, a pentagon can NOT be a cross-section of a triangular prism.
Step-by-step explanation:
Prisms have a uniform cross-section and are named after their cross-section. Hence, the cross section of a triangular prism is a triangle. The only prism with a pentagon cross-section is a pentagonal prism.

The product of two numbers is 37.03.If one number is 2.3,find the other.
Answer:
16.1
Step-by-step explanation:
37.03/2.3 = 16.1
Answer:
[tex]\boxed{\bold{\huge{\boxed{16.1}}}}[/tex]
Step-by-step explanation:
Let the first number be x and the second number be y
So, the condition is:
[tex]x * y = 37.03[/tex]
Given that x = 2.3
[tex]2.3 * y = 37.03[/tex]
Dividing both sides by 2.3
[tex]y = \frac{37.03}{2.3}[/tex]
[tex]y = 16.1[/tex]

question in picture
Answer:
The low is -13 degrees Fahrenheit. The high is 109.4 or 109 2/5 degrees Fahrenheit.
Step-by-step explanation:
To get the low you plug -25 in for C(Celsius) and then you solve for F. First you can multiply both sides by nine. Second you need to distribute the 5, and this will give you 5F-160. Next add 160 to both sides, and now you should have, -65 = 5F. And finally you divide both sides by five to get a final answer of F = -13. To get the high follow these steps again, except this time plug in 43 for C.
