Answer:
25%
Step-by-step explanation:
Let's call the factor by which production increased x.
[tex]x\cdot 84=105 \\\\\\x=\dfrac{105}{84}=1.25[/tex]
To find the percent increase, you need to subtract 1 from this value, because that represents the initial amount of robots produced. 1.25-1=0.25. Now, to find the percentage:
[tex]0.25=\dfrac{25}{100}=25\%[/tex]
Hope this helps!
Answer:
25%solution,
[tex]percent \: increase = \\ [/tex]
[tex] (\frac{105 - 84}{84}) \times 100 \: percent \\ = \frac{21}{84} \times 100 \: percent \\ = 25 \: percent[/tex]
Hope this helps..

The mean age of a herd of cows is 7.9 years. A cow that is 0.5 years old is
added to the herd. How does this cow's age affect the mean?
Answers
Answer: The new mean will be less than 7.9 years
Step-by-step explanation:
The mean is the same thing as the average. Because 0.5 is less than 7.9, the average will also decrease.
Hope it helps <3
Answer:
Hey there!
The new mean will be less than 7.9 years of age.
The mean is the average, thus if you add something below the average, the entire mean will decrease, and if you add something above the average, then vice versa.

A recipe requires 1.5 kilograms of eggs. How much is this in pounds? 0.15 0.7 1.5 2.2 3.3
Answers
Answer:
3.3 Pound
Step-by-step explanation:
in this problem we have to convert kilogram value to its equivalent pound value.
we know
1 KG = 2.205 Pound
since we have to find value of 1.5 kg
we multiply both LHS and RHS by 1.5
1 * 1.5 KG = 2.205 * 1.5 Pound
=> 1.5 KG = 3.307 Pound.
Since , in option value is rounded to 1 decimal place,
hence correct choice is 3.3 Pound

From the graph y = 10/x^2 shown below, what happens to the y- values as the negative x- values get closer to zero?
a.
They increase
c.
They stay the same
b.
They decrease
d.

Answers
Answer: a
Step-by-step explanation:
if you look on the x axis and go from the far left to 0 you can see the y values go up and increase.
The y- values as the negative x- values get closer to zero is they decrease the correct option is B.
How to find the function which used to make graph?There are many tools we can use to find the information of the relation which was used to form the graph.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
We are given that;
The function= y = 10/x^2
Now,
As x gets closer to 0 from the negative side, x becomes a larger negative number in magnitude. When we substitute a large negative value for x in y = 10/x^2, the square of this negative number becomes a large positive number, and the fraction 10/x^2 becomes a small positive number.
For example, if we substitute x = -2 into y = 10/x^2, we get:
y = 10/(-2)^2 = 10/4 = 2.5
If we substitute x = -10 into y = 10/x^2, we get:
y = 10/(-10)^2 = 10/100 = 0.1
Therefore, by the graphed function the answer will be they decrease.

The function h = -16t + 240t represents the height h (in feet) of a rocket t seconds after it is launched. The rocket explodes at its highest point. after how many seconds does the rocket explode
Answers
The height of the rocket at time t is given by the function h = -16t + 240t. The rocket explodes at its highest point, which occurs at the vertex of the parabolic path described by this function.
The vertex of the parabola h = -16t^2 + 240t can be found using the formula t = -b/2a, where a is the coefficient of the squared term (-16 in this case) and b is the coefficient of the linear term (240 in this case).
In this case, a = -16 and b = 240, so the time t at which the rocket reaches its highest point is:
t = -b / 2a
t = -240 / (2 * -16)
t = -240 / -32
t = 7.5
Therefore, the rocket reaches its highest point 7.5 seconds after it is launched, and it explodes at this point.
Note that the negative value for t obtained in the equation t = -b/2a is ignored in this case, since time cannot be negative.

Consider the given inequalities are
[tex]y-x>-4[/tex]

If (2,3) is solution of given system of inequalities, then the above inequalities must be satisfy by the point (2,3).

Answers
Answer:
The correct option is D
D) the height of the rock 3.2 seconds after it is propelled
Question:
The question is incomplete as it doesn't say what to find. I know that whole question which is given below
The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot.What does h(3.2) represent?
A) the height of the rock 3.2 seconds before it reaches the ground
B) the time it takes the rock to reach the ground, or 3.2 seconds
C) the time it takes the rock to reach a height of 3.2 meters
D) the height of the rock 3.2 seconds after it is propelled
Solution:
h(t) represents the the height of the rock t seconds after it has propelled, where t is the time. If we take t=3.2, it means that we can find the height of the rock 3.2 seconds after it has been propelled by a slingshot, which is represented by the function h(t). Since the explanation given matches the option D, option D is the correct option.

Answers
Answer: A.1100
Step-by-step explanation:
Hi, to answer this question we have to round each number to the nearest whole number:
110.4 = 110 (.4 is less than 5)
10.2 = 10
The product is the result of the multiplication of both numbers:
110 x 10 = 1,100

You gave us the speed and the frequency, and you need the wavelength.

So . . . F x W = 343 m/s

W = (343 m/s) / (240 / s)
W = (343/240) m

the figure below is a semi circle with two smaller semi circles cut out from it.The radius of the small semi circle is 3cm.
find the area of the shaded portion
Answers
So basically all you have to do is find the area of one of the smaller semi circles by using the formula for the area of a circle (A=πr^2). You know that the length of the larger semi circle's radius is equivalent to 6 cm because the radius of the smaller ones are 3 cm, meaning the diameter would have to be 6 cm and in this case, the length of the smaller semi circles' diameters is equal to the radius of the big semi circle. Then you would find the area of the big semi circle again by using the area of a circle formula, but after getting the answer you would half it, obviously because it's a semi circle. Subtract the are of the smaller semi circle you found earlier from the answer you just got and that's it ;) (you wouldn't have to half the area since there are two smaller semi circles and 1/2 + 1/2 = 1 but u knew that)
Put simply, the answer would be about 88.2644 cm because circles.
