Kylie is preparing for the science fair that will take place in six weeks. She has three plants that she has grown from seeds, which she considers to have height 0 centimeters, and she is measuring their heights as she applies different treatments to each. The second plant is receiving Plant Food B. After 3 weeks, it is 10 centimeters tall. If it continues growing at this rate, how tall will it be after 6 weeks?
The height of plant B growing at a rate of 3.33 centimeters per week should have a height of 19.98 cms.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
First we need two points (x, y) to obtain the slope.
Assuming height to be 'y' and weeks to be 'x'.
Therefore, (0, 0) and (3, 10) are the two points.
Slope(m) = (10 0)/(3 - 0).
Slope(m) = 10/3.
Slope(m) = 3.33
Now, To obtain the y-intercept.
10 = 3(3.33) + b
b = 0.01 Or neglegible.
Therefore y = 3.3x.
Now, In the 6th week, the height of plant B will be,
y = 3.33(6).
y = 19.98 or 20 cm.

Eight toy camels and three toy pigs cost Gary $85. Twelve toy camels cost Sherry $96. Assuming everyone bought their toys at the same store and there were no discounts, what is the cost of two toy pigs?
Answer:
2 toy pigs cost $14
Step-by-step explanation:
If 12 toy camels cost $96, I can solve ($96 / 12 = $8) to find the price of 1 toy camel. Now, I know that 1 toy camel costs $8.
If 8 toy camels and 3 toy pigs cost $85, I can multiply the price of 1 toy camel by 8 and solve ($8 x 8 = $64).
Next, I can subtract Gary's total cost by the toy camels to find how much was spent on 3 toy pigs. ($85 - $64 = $21) Therefore, 3 toy pigs cost $21.
Then, I can solve ($21 / 3 = $7) to find the price of 1 toy pig. Finally, I can multiply ($7 x 2 = $14) to find that 2 toy pigs cost $14.
Answer:
Two toy pigs cost $14.
Step-by-step explanation:
Gary bought 8 toy camels and 3 toy pigs for $85.
Sherry bought 12 toy camels for $96.
Thus, each toy camel cost $96/12=$8
Now we know Gary spent 8*$8= $64 in toy camels.
The rest of the $85, $85 - $64 = $21 was spent on the 3 toy pigs, thus each toy pig cost $21/3=$7
If one toy pig costs $7, two toy pigs cost $14.

There were 400 sweets in a pack. The principal of a school bought 25 such packs of sweets for 2000 children o Children's Day. If each child was given 7 sweets, how many more packs of sweets were needed?
Answer:
10 more packs
Step-by-step explanation:
400 sweets bought 25 such packs = 400*25=10000
2000 each one gets 7 = 2000*7=14000
14000-10000=4000
4000/400 is 10.
So 10 more packs.
Hit the crown :D
Answer:
Step-by-step explanation:
400 sweets in a pack * 25 packs = 10,000 sweets
2000 kids * 7 sweets = 14,000
We need 4,000 more sweets. That would be 10 packs more since there are 400 sweets in a pack.

a distributor wants to make 1000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is 20% raisins. How many pounds of each should he use?
Answer:
200 pounds 20% raisins
800 pounds 5% raisins
Step-by-step explanation:
Let number of 5% be x
and number of 20% be y
x + y = 1000
Also;
5% of x + 20-% of y = 8% of 1000 pounds
= 0.05x + 0.2y = 80
From i , x = 1000-y
0.05(1000-y) + 0.2y = 80
50-0.05y + 0.2y = 80
0.15y = 30
y = 200
x = 1000 - y
= 1000-200 = 800
He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.
Given that,
A distributor wants to make 1000 pounds of trail mix that is 8% raisins.
He will use a mix that is 5% raisins and a mix that is 20% raisins.
We have to determine,
How many pounds of each should he use.
According to the question,
Let number of 5% raisins be x,
And number of 20% raisins be y.
Then,
He will use a mix that is 5% raisins + A mix that is 20% raisins = Distributor trail mix.
[tex]x + y = 1000[/tex]
And,
He will use a mix that is 5% raisins of x + and a mix that is 20% raisins of y = 1000 pounds of trail mix that is 8% raisins.
5% of x + 20% of y = 1000 of 8% raisins
[tex]0.05 x+ 0.20y = 80[/tex]
On solving both the equation,
[tex]x + y =1000\\\\x = 1000-y[/tex]
Substitute the value of x in the equation 2,
[tex]0.05 (1000-y) + 0.20y = 80\\\\0.05 \times 1000 - 0.05y + 0.20y = 80\\\\50 + 0.15y = 80\\\\0.15y = 80-50 \\\\0.15y = 30\\\\y = \dfrac{30}{0.15}\\\\y = 200[/tex]
Substitute the value of y in the equation 1,
[tex]x + y = 1000\\\\x + 200 = 1000\\\\x = 1000-200\\\\x = 800[/tex]
He will use x = 800 pounds a mix that is 5% raisins and y = 200 pounds for a mix that is 20% raisins.
Hence, He will use 800 pounds for a mix that is 5% raisins and 200 pounds for a mix that is 20% raisins.

A. There must be an even number of data values in the data set to create a histogram.
B. This data set would yield a histogram that is not bell-shaped.
C. Adequate class boundaries for a histogram cannot be found with this data set.
D. With a data set that is so small, the true nature of the distribution cannot be seen with a histogram.
Answer:
The correct option is D.
Step-by-step explanation:
A histogram is a bar chart wherein the horizontal scale signifies class interval (or classes of data values) and the vertical scale signifies frequencies or percentages. The altitudes of the columns relate to the frequency values, and the columns are drawn together without breaks.
The histogram has the following properties:
• Shows the shape of distribution
• Shows the location of center
• Shows the spread of data
• Helps in identifying outliers
Since the sample collected is so small, the true nature of the distribution cannot be seen with a histogram.
Thus, the correct option is D.

Step-by-step explanation:
4z^3 · z^2 · 5z
first, multiply 4z · 1z = 4z and add the exponents 3 + 2 = 5
4z^5 · 5z
multiply 4z · 5z and keep the exponents
20z^5
2m^3p^4 · 4m^2p^3 · 3mp^0
find just the "m" variables: 2m^3 · 4m^2 and same as before multiply then add the exponents = 8m^5
now do the same for the "p" variables: 3p^4 · 2p^3 = 6p^7
and for the "mp" variable: 3mp^0
put it all together and this is the simplest form because we don;t know the values of the variables:

For the function F defined by F(x)=x2−2x+4, find F(−2).
Answer:
F(-2) = 12
Step-by-step explanation:
F(-2) = (-2)²- 2(-2) + 4
= 4 - (-4) + 4
= 4 + 4 + 4
= 12
The required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.
A quadratic function is given F(x) = x² − 2x + 4, value of the function is to be determined at x = -2.
What is a polynomial function?
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
F(x) = x² − 2x + 4
Above given function is a quadratic function,
in order to find F(-2) , we have to put x = -2 in above given function.
F( -2 ) = ( -2 )² − 2( -2 ) + 4
F( -2 ) = 4 + 4 + 4
F( -2 ) = 16
Thus, the required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.
