Answer:
Ok, first we have the relation:
Speed = Distance/Time.
Here we have:
Distance = 24m
Time = 87 mins
Speed = 24m/87mins = 0.279 m/min.
Now, in 6 minutes, the distance moved will be (remember that the movement is downwards)
D(6min) = (0.279m/min)*6min = 1.66 m.
So in 6 minutes, it moves 1.66 meters down, if the initial position is 10m above the ground, then the position after 6 minutes is:
10m - 1.66m = 8.34m above the ground.
And after 70 minutes, the distance moved is:
D(70min) = (0.279m/min)*70min = 19.53m
Again, the initial position is 10m above the ground, so after 70 minutes the position is:
10m - 19.53m = -9.53m
So after 70 minutes, the position is 9.53 meters under the ground.
The lift will go 2.76m deep from the surface after 70 mins.
The lift moves down 24m in 87 minutes.
What is the speed of an object that covers 'd' distance in 't' time?The speed of an object that covers 'd' distance in 't' time is d/t.
So, speed of the lift = 24/87 = 3/29m/min
Distance covered in 6 minutes = 6 * 3/29 = 18/29 m
So, if initially lift is at the surface of the earth, it will go 18/29m below the surface.
Distance covered in 70 minutes = 70* 3/29 =210/29m
So, if the initially lift is at 10 m height, it will go (10-210/29) = -80/29 or 2.76m below the surface of the earth.
Therefore, the lift will go 2.76m deep from the surface after 70 mins.

Darren has 84 DIMES and 144 PENNIES in his piggy bank.
Eugene has 63 DIMES
and 112 PENNIES in his piggy bank.
Who has the higher ratio of DIMES TO PENNIES in their piggy bank?
Answer:
Step-by-step explanation:
Darren has 84 DIMES and 144 PENNIES:
the ratio of dimes to penny=84/144=7/12
12 is GCF : 84/12=7, 144/12=12
Eugene has 63 DIMES and 112 PENNIES :
the ratio is 63/112=9/16
GCF of (63 and 112) is 7 : 63/7=9 , 112/7=16
7/12 = 0.58333 9/16=0.5625
7/12 is higher than 9/16
Darren has the higher ratio of DIMES TO PENNIES in his piggy bank
this can be solved by finding the percentage 7/12=0.5833=58.3% and 9/16=0.5625 which is 56.25%

She can wash 99 cars in 9 days.
Divide number of cars by number of days.
99 cars / 9 days ⇒ 11 cars/day ⇒ 11 cars per day.
An 8-cup carton of milk costs $2.00. What is the price per pint?
Answer:
$0.50 per pint
Step-by-step explanation:
First, we need to convert cups to pints.
There are 2 cups in 1 pint. We are given 8 cups, which is 4 times 2. So, we multiply 1 pint by 4:
1 * 4 = 4 pints
There are 4 pints in 8 cups.
We also know that 8 cups cost $2, which also means that 4 pints cost $2.
To find the cost per pint, we divide 2 by 4:
2 / 4 = $0.50
Thus, the price is $0.50 per pint.

Answer:
Option D. 2x⁷ - 12x⁶ + 10x⁵
Step-by-step explanation:
From the question given:
Length (L) = 2x²
Width (w) = x³
Height (h) = x² - 6x + 5
Volume (V) =?
Volume (V) = length (L) x width (w) x height (h)
V = L x w x h
V = 2x² × x³ × x² - 6x + 5
V = (2x²) (x³) (x² - 6x + 5)
V = (2x⁵) (x² - 6x + 5)
Clear bracket
V = 2x⁷ - 12x⁶ + 10x⁵
Therefore, the volume of the cube is 2x⁷ - 12x⁶ + 10x⁵

Greetings from Brasil...
We know that the sum of the internal angles of a triangle is 180....
Bringing to our problem:
Angle P + Angle R + Angle S = 180
43 + 79 + Angle S = 180
Angle S = 180 - 43 - 79
Angle S = 58given the equation p=2n-3 , what is p when =3
Answer:
3
Step-by-step explanation:
Hello!
It is asking for the answer is p is equal to 3 so we put 3 in for p
3 = 2n - 3
Add 3 to both sides
6 = 2n
Divide both sides by 2
3 = n
The answer is 3
Hope this helps!
Answer:
n = 3
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:
*3-(2*n-3)=0
Pull out like factors:
*6 - 2n = -2 • (n - 3)
Solve:
*-2 = 0 (This has no equation so we solve for the next side.)
*n-3 = 0 (Add 3 to both sides)

Solve 13u2+23u=−112 by using the quadratic formula. Give an exact answer and simplify any fractions. If there are multiple answers, list them separated by a comma, e.g. 1,2. If there is no solution, enter ∅.
Note: this is assuming you haven't reached complex numbers yet
=============================================================
Explanation:
The given equation 13u^2+23u = -112 is the same as 13x^2+23x = -112
and we can add 112 to both sides getting 13x^2+23x+112 = 0
We see the equation is in the form ax^2+bx+c = 0
The discriminant is
D = b^2 - 4ac
D = 23^2 - 4(13)(112)
D = -5295
The negative discriminant means there are no real number solutions.
-----------
Extra info:
If D = 0, then there would be exactly one real number solution.
If D > 0, then there would be two distinct real number solutions.
Answer:
it is complex solution
no real number solution
Step-by-step explanation:
13u²+23u=-112
13u²+23u+112=0
a=13, b=23 , c=+112
u= (-b±√(b²-4ac))/2a
u=[(-23±√(23)²-4(13)(112)]/2(13)
u=(-23±√-5295)/26
u=(-23±i√5295)/26
What’s the value of X In this????
Answer:
x = 68 degrees
Step-by-step explanation:
Step 1: We know this is a isosceles triangle
Since we know it is a isosceles triangle it has 2 of the same angle so the unknown side(not x) is 59
Step 2: Use the 2 angles to find 'x'
Angles in a triangle add up to 180 so we subtract 59 x 2 from 180 to get 68
Therefore angle x is 68 degrees
Answer:
X = 68Step-by-step explanation:
This is because u have to do the math - LOL
1. What do you haveSo
- an isosceles has 2 same sides. The pic shows an isosceles triangle
- 2 sides are the same which is 4
- 1 side is different and is 1.5
2. Steps to solveSame length = Same angles
So
- 4 = 4
- 56 = 56
3. Finding the angle.Total angle - angle 1 - angle 2 = angle 3 or ?
- Total angle = 180
- Angle 1 = 56
- Angle 2 = 56
- Angle 3 = ?
180 - 56 - 56 = 68

Look at the graph:
What is the relationship between x and y?
A: y and x stay constant
B: y increases as x increases
C: y decreases as c increases
D: y stays constant as x increases
Answer:
C: y decreases as x increases
Step-by-step explanation:
Notice from this graph, as we move from left to right, the y values are decreasing while the x values are increasing.
This means that the relationship of the line in terms of x and y can be described as, as y decreases, x increase. Hence you will choose option C.
You can validate this by choosing to definitive points on the line, say the origin (0,0) and (2, -6). Notice that our x value increased, but our y value decreased.

This is for algebra 2 can someone tell me if I’m right and can someone explain how do you get a= ?
Answers:
a = 2
h = 3
k = -3
You have the correct h and k values. Nice work so far.
==========================================================
Explanation:
(h,k) is the vertex. So (h,k) = (3,-3) meaning h = 3 and k = -3
To get the value of 'a', we need to plug in some point on the red graph. Each point is of the form (x,y). We can pick any point we want that isn't the vertex.
Let's pick (0,3) which is the y intercept. I'm picking this because 0 is an easy number to work with
------------
y = a|x-h| + k
y = a|x-3| + (-3) .... plug in the h,k values
y = a|x-3| - 3
3 = a|0-3| - 3 .... plug in (x,y) = (0,3)
3 = a|-3| - 3
3 = a*3 - 3
3 = 3a - 3
3a-3 = 3
3a = 3+3 ... adding 3 to both sides
3a = 6
a = 6/3 ... divide both sides by 3
a = 2
The value a = 2 indicates that the parent function y = |x| has been stretched vertically by a factor of 2. So it is twice as tall as before. Then it has been shifted to place the vertex at (3,-3) as shown in the graph.
------------
You may be wondering why you can't pick on the vertex for (x,y)
Let's see what happens if we use (x,y) = (3,-3)
y = a|x-3| - 3
-3 = a|3-3| - 3 ... plug in (x,y) = (3,-3)
-3 = a|0| - 3 ... uh oh, we get 0 here
-3 = a*0 - 3
-3 = 0 - 3
-3 = -3
We get a true statement, which is nice, but it doesn't tell us anything about what the value of 'a' is. That 'a' term goes away entirely. So I avoided using x = 3 to prevent x-3 from being 0.
