Answer:
The position of the equipment elevator is 315 feet deep.
The position of the elevator of the miners is 208 feet deep.
At that time, the equipment elevator is deeper.
Step-by-step explanation:
Observation: Seems the numbers are doubled. 77 instead of 7; 1313 instead of 13; 2929 instead of 29; and 1616 instead of 16.
Hence, the question is:
A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 7 feet per second. The elevator for the miners descends 13 feet per second. One day, the equipment elevator begins to descend. After 29 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 16 seconds? At that time, which elevator is deeper?
Step-by-step explanation:
From the question,
For the equipment elevator
Speed= 7 feet/second
For the elevator of the miners,
Speed= 13 feet/second
To determine the positions of each elevator relative to the surface, we will determine the distance each of the elevator descends.
From the formula
Speed= Distance / Time
Then,
Distance = Speed × Time
From the question,
The equipment elevator begins to descend and after 29 seconds, the elevator for the miners begins to descend. To determine the position of each elevator after another 16 seconds. That is, the equipment elevator descends for a total of (29+16) seconds and the elevator of the miners descends for 16 seconds.
For the equipment elevator
Speed= 7 feet/second
Time = 29 + 16 seconds = 45 seconds
From, Distance = Speed × Time
∴ Distance = 7 feet/second × 45 seconds
Distance = 315 feet
Hence, the position of the equipment elevator is 315 feet deep.
For the elevator of the miners
Speed = 13 feet/second
Time = 16 seconds
Distance = Speed × Time
∴ Distance = 13 feet/second × 16 seconds
Distance = 208 feet
Hence, the position of the elevator of the miners is 208 feet deep.
At that time the equipment elevator is deeper.

Answer:
3/2
Step-by-step explanation:
Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7

Two years ago a company purchased 500 dozen pencils at 40 cents per dozen. This
year, only 75% as many pencils were purchased as were purchased two years ago, but
the price was 20% higher than the old price. What was the total cost of pencils
purchased by the company this year?
Answer:
180$
Step-by-step explanation:
First you have to find out how many pencils the company bought each year which is 6000 since they bought 500 dozens and 75% of 500 is 375 and 20% of 0.40 is 0.08 so the cost for each dozen pencils would be 180$ (Sorry if this is wrong I'm 80% sure)

The engineers designing the All Aboard Railroad between Boca Raton and Jupiter decide to create parallel tracks through this portion of the railway. To illustrate their plans to the county commission, they use a coordinate plane. The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2)?
Answer:
there are no signs between the x and y and constant
it could be
2x+5y=15
2x+5y=-15
-2x+5y=15
2x-5y=15
for ax+by=c, the equation of a line paralell to that is
ax+by=d where a=a, b=b, and c and d are constants
(for this answer, I'm going to use 2x+5y=15)
given 2x+5y=15, the equation of a line paralell to that is 2x+5y=d
to find d, subsitute the point (4,-2), basically put 4 in for x and -2 for y to get the constant
2x+5y=d
2(4)+5(-2)=d
8-10=d
-2=d
the eqaution is 2x+5y=-2 (Only if the original equation is 2x+5y=-15
pls mark me brainlest

Rapid Rental Car Company charges a $55 rental fee and $0.25 per mile driven. For the same car, Capital Cars charges $45 for rental fee and $0.35 per mile. Write an equation and find the number of miles for which the companies’ charges will be the same.
Answer:
100 miles
Step-by-step explanation:
Let the number of miles driven = x
Rapid Rental Car Company charges a $55 rental fee and $0.25 per mile driven.
$55 + $0.25x
55 + 0.25x
For the same car, Capital Cars charges $45 for rental fee and $0.35 per mile.
$45 + $0.35x
45 + 0.35x
Equation :
55 + 0.25x = 45 + 0.35x
The number of miles for which the companies’ charges will be the same is calculated as:
55 + 0.25x = 45 + 0.35x
Collect like terms
55 - 45 = 0.35x - 0.25x
10 = 0.10x
x = 10/0.10
x = 100 miles
The number of miles for which the companies’ charges will be the same is
100 miles.

What is Associative Property?The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Given:
We have (3 x 8) x 4 = 3 x ( )
We know from associative Property
a x ( bx c) = (a x b) x c
Here a= 3, b=8 and c= 4
So, (3 x 8) x 4 = 3 x ( 8 x 4).

Peter has many socks, all the same except that they are in three different colours. He is leaving to catch an early train to go on a business trip, and he does not want to wake his wife, so he packs in the
dark. He needs eleven pairs of socks, each sock in each pair the same colour. How many socks must he take from his drawer to be sure of achieving this?
Answer:
24 socks
Step-by-step explanation:
The given parameters are;
The number of different colors of socks = 3
Therefore, we have the worst case, the first three socks are different colors, since there are three different colors, the fourth socks is first pair in the worst case scenario
After which, every other two socks makes a pair in the worst case process, the number of socks he must take to make sure he has eleven pairs are given by the pairing table
Number of socks 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

O 116°
Sum of the interior angles of any triangle equal 180° ;
So :
90° + 24° + T = 180°
114° + T = 180°
subtract both sides 114
T = 180° - 114°
T = 66°

Fabio is driving west away from Albany and towards buffalo along interstate 90 at a constant rate of speed of 62 miles per hour. After driving for 1.5 hours Fabio is 221 miles from Albany
Answer:
The distance between Albany and Buffalo along the I90 is 288.8 mi.
The speed of Fabio is 62 mph.
After 1.5 hours, he is 221 miles from Albany.
Things we can calculate here:
Using the relation:
Distance = time*speed.
We can calculate the number of miles that he moved in that 1.5 hours.
D = 62mph*1.5h = 93mi.
If after 1.5 hours, he was 221 miles Albany, then before that he was 93 miles closer to Albany.
His initial position was:
221 - 93 = 128 miles away from Albany.
Now we also can calculate the time left to arrive at Buffalo.
We know that the distance between Albany and Buffalo is 288.8 mi
And he is 221 mi away from Albany.
Then the distance left to Buffalo is:
288.8mi - 221mi = 67.8mi
And the time left will be:
Distance/speed = time
67.8mi/62mph = 1.1 hours.
He needs to drive for another 1.1 hours to get to Buffalo.

Please solve for X helppp
Answer:
x = 91
Step-by-step explanation:
The sum of the 4 interior angles of a quadrilateral = 360°
Sum the 4 angles and equate to 360, that is
x + 10 + x - 10 + x + 6 + x - 10 = 360 , then
4x - 4 = 360 ( add 4 to both sides )
4x = 364 ( divide both sides by 4 )
x = 91
