a factory could produce 84 toy robots in one day. They purchased some new equipment. Now they can produce 105 robots in one day. what is the percent gain?
Answer:
The answer to the question is
25 % increase in production rate
Step-by-step explanation:
To solve the question, we note that
Initial number of products = 84 toy robots per day
Present production rate = 105 robots per day
The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100
Where increase in production rate = 105 - 84 = 21
Percentage increase = 21/84 ×100 = 25 % increase
If the elevator ascends or GOES UP 80 meters, is
that represented by 80 or -80?
Answer:
80
Step-by-step explanation:
Explain how you solved this problem.
Answer:
(-20)
Step-by-step explanation:
-4 - 2(4 + (-2) )³ = -4 - 2(4 - 2)³
= -4 - 2*(2)³
= -4 - 2* 8
= -4 - 16
= -20

If the sum of the measures of the interior
angles of a polygon is 1930°, how many sides
does it have?
Answer:
Thus, the number of sides: n ≈ 13 (rounded to the nearest whole number).
Step-by-step explanation:
We know that the formula of the sum of the measures of the interior angles of a polygon
Sum = (n-2) × 180°
where
n is the number of sides
In your case, since the sum of the interior angles is 1930°, then
1930° = (n-2) × 180°
so we can determine the number of sides n, such as
1930 / 180 = n-2
[1930 / 180] + 2 = n
n ≈ 12.7
If 12.7 rounded to the nearest whole number, then
n ≈ 13
Thus, the number of sides: n ≈ 13 (rounded to the nearest whole number).

Answer:
x = 30
Step-by-step explanation:
Supplementary angles total 180°.
5x° +x° = 180°
6x = 180
x = 180/6 = 30
The value of x is 30.
Stanley has a collection of seashells. He found 35% of his collection on Florida beaches. If Stanley has 49 seashells from Florida, how many seashells does he have in his collection all together?
A) 90
B) 120
C) 140
D) 160
Answer:
140 shells. So, C
Step-by-step explanation:
Let x equal the total number of shells in Stanley's collection. Then,
.35 x = 49
x = 49 / .35
x = 140
Can someone help me please?
Answer:
[tex]x=\sqrt{12}[/tex]
Step-by-step explanation:
The Pythagorean theorem states that [tex]a^2+b^2=c^2[/tex] in a right triangle where c is the longest side. To solve for x, we plug in the side lengths given as a and c.
[tex]a^2+b^2=c^2\\2^2+x^2=4^2[/tex]
Move 2² to the other side to isolate b²
[tex]x^2=4^2-2^2[/tex]
Square root both sides to isolate b
[tex]x=\sqrt{4^2-2^2}\\x=\sqrt{16-4} \\x=\sqrt{12}[/tex]

which expression shows the correct way to expand (6x-6)^2?
Answer:
[tex](6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36[/tex]
Step-by-step explanation:
Even if I don't know the options I can give all the option that will be right for expending this. Just look at each step and see which one is one of the options.
[tex](6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36[/tex]

George spent 32,000 points for an upgrade in a video game. He spent 5/8 of the points on a castle and the rest on a spell. How many points did George spend on the castle and how many did he spend on the spell?
Answer:
He spent 20,000 points on the castle and 12,000 points on the spell.
Step-by-step explanation:
It says that he spent 5/8 points on the castle
32000/1 x 5/8 = 20,000
We got our points for the castle. Now we need to find how many points for the spells, which is the remaining. 32000-20,000=12,000
This means that 20,000 points are used on the castle and 12,000 on the spell.
Answer:20000 and 12000

How can you use the coordinates of two points on a line to determine the slope of the line?
Answer:
you can use the slope intercept formula!
y2-y1/x2-x1
Step-by-step explanation:
lets take an example!
the coordinates of 1 point are (2,4) and the other point is (4,6)
so lets plug in (x1,y1) (y1,y2)y2 is the y intercept of second point so it is 6 minus y1 which is 4.
6-4/x2-x1
lets do same for x!
6-4/4-2
lets solve
2/2
=1
the slope is 1

If your first first oil changes 5000 miles and then every three hundred three thousand miles after if you drive your car 250 miles a week how many oil changes will you need the first year
Answer:
4 oil changes
Step-by-step explanation:
Given that:
Distance after first oil change = 5000 miles
Subsequent oil changes = 3300 miles
If distance in miles moved per week = 250 m
Number of weeks per year = 52
Total miles moved per year = (250 * 52) = 13000 miles
Let Number of oil change per year = n
Difference between successive oil change = d = 3300 miles
Using the relation :
Total miles = Ist change + (n - 1)d
13000 = 5000 + (n - 1)3300
13000 = 5000 + 3300n - 3300
13000 = 1700 + 3300n
13000 - 1700 = 3300n
11300 = 3300n
n = 3.424
Hence, number of oil. Changes in first year = 4
Write 0.4% as a fraction or mixed number in simplest form.
Answer:
1/250
Step-by-step explanation:
0.4% = 0.004 = [tex]\frac{4}{1000}[/tex]
divide numerator and denominator of [tex]\frac{4}{1000}[/tex] by 4 to get [tex]\frac{1}{250}[/tex]

Which recursive formula fits the following pattern? 50, 25, 12.5, 6.25, 3.125...
Answer:
1.5625
Step-by-step explanation:
Find the ratio (r) between adjacent members: 50,25,12.5,6.25,3.125
a_2/a_1=25/50=0.5
a_3/a_2=12.5/25=0.5
a_4/a_3=6.25/12.5=0.5
a_5/a_4=3.125/6.25=0.5
The ration (r) between every two adjacent members of the series is constant and equal to 0.5 thus:
a_6 =a_1×(^r6-1) =a_1×r^5 =50×0.5^5 =1.5625

Hurry up please I have 27 minutes to anwser 25 guestions
Answer:
C. The relationship between the quantities is: add 25.
Step-by-step explanation:
1x = 25y,
2x = 25 + 25 = 50y
3x = 50 + 25 = 75y
4x = 75 + 25 = 100y
Note:
As you can see, every time the number goes up on the chart, it goes up by 25 and you can find that out by just simply adding 25 to the first number and seeing if it matches up with the next, (which I did above).
