A plot of land doubles in size by adding x meters to the length and x meters to the width of the land?if the original plot had an area of 200 by 300 meters ,what is the value x?
Answers
Answer:
x = 100
Step-by-step explanation:
The larger area is ...
A = LW
A = (300+x)(200+x) = x^2 +500x +60,000
The smaller area is ...
A = (200)(300) = 60,000
We want the larger area to be double the smaller area, so ...
x^2 +500x +60,000 = 2(60,000)
x^2 +500x = 60,000 . . . . . . . . . . . . subtract 60,000
x^2 +500x + 62500 = 122500 . . . add 250^2 to complete the square
(x +250)^2 = 350^2
We're interested in the positive solution, so we can take the positive square root to find it:
x +250 = 350
x = 100 . . . . . . . . . subtract 250
_____
The graph shows the quadratic in the form x^2 +500x -60,000. That is, we're looking for zeros (x-intercepts) of the function.
If 8 drinks cost 12 dollars how much will 12 drinks cost
Answers
Hello there for this problem we can make a proportion
[tex]\frac{8\:drinks}{12\:cost}=\frac{12\:drinks}{x}[/tex], we are trying to find how much x is
cross multiply and we get that [tex]8x=144[/tex]
divide both sides by 8 and we get [tex]x=18[/tex], 12 drinks would've cost 18 dollars
Answer:
1 drink = 12 ÷ 8

If 2 caterpillars eat 6 leaves each day, how many leaves do 12 caterpillars need each day?
Answers
2 caterpillars = 6 leaves
We’ve been told to work out how many leaves 12 caterpillars eat each day.
So we can fill in our extra information…
2 caterpillars = 6 leaves
12 caterpillars = x leaves
From 2 to 12, we have multiplied by 6. What we do to one side, we must do to the other. Therefore, 6 x 6 = 36 leaves.
So for 12 caterpillars, they eat 36 leaves each day.

Find the area of the shaded region.
.7761
.2177
.3650
.7823
Answers
Using the normal distribution, it is found that the area of the shaded region is of 0.7823.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of 59, hence [tex]\mu = 59[/tex].The standard deviation is of 7, hence [tex]\sigma = 7[/tex].The shaded region is the region to the left of 64.2, hence it's area is the p-value of Z when X = 64.2.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{64.2 - 59}{6.7}[/tex]
[tex]Z = 0.7761[/tex]
[tex]Z = 0.7761[/tex] has a p-value of 0.7823.
The area of the shaded region is of 0.7823.

Answers
Answer:
13
Step-by-step explanation:
The proportion is solved and the number of muffins is M = 16
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
The ratio of cookies to muffins made at The Berry Bakery is 3 : 4
Now , the number of cookies is = 12
So , the proportion is
3 / 4 = 12 / M
Multiply by M on both sides , we get
( 3/4 )M = 12
Divide by 3/4 on both sides , we get
M = 16 muffins
Hence , the number of muffins is 16

The sequence of transformation is a reflection across the x-axis, followed by horizontal shift to the right by 2 units, and vertical shift up by 6 units
The vertices of triangle ABC are given as:
[tex]A = (1,9)[/tex]
[tex]B = (3,12)[/tex]
[tex]C =(4,4)[/tex]
The vertices of triangle A"B"C" are given as:
[tex]A" = (3,-3)[/tex]
[tex]B" = (5,-6)[/tex]
[tex]C" =(6,2)[/tex]
Start by reflecting the coordinates of triangle ABC across the x-axis.
The rule of this transformation is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex]A' =(1,-9)[/tex]
[tex]B' =(3,-12)[/tex]
[tex]C' =(4,-4)[/tex]
Next, shift triangle A'B'C' 2 units right and 6 units up
The rule of this transformation is:
[tex](x,y) \to (x+2,y+6)[/tex]
So, we have:
[tex]A" = (3,-3)[/tex]
[tex]B" = (5,-6)[/tex]
[tex]C" =(6,2)[/tex]
Hence, the sequence of transformation is a reflection across the x-axis, followed by horizontal shift to the right by 2 units, and vertical shift up by 6 units

Answers
Answer:
C
Step-by-step explanation:
We can solve this by analyzing if the event causes the result. If it does not, then there is correlation but not necessarily causation
A. Event: Rainfall. Result: Water level rises
Does rainfall cause an increase in water level? Yes, so this is incorrect
B. Event: Temperature increase. Result: Ice melting
Does an increase in temperature cause ice to melt faster? Yes, so this is incorrect
C. Event: More people have vision loss. Result: Hearing aids sales increase
Does more people having vision loss cause hearing aids sales to increase? No, vision loss does not cause a need for hearing aids -- hearing loss would, but vision loss does not. This is correct
D. Event: A student makes fewer mistakes. Result: A better grade
Do fewer mistakes cause better grades? Yes, so this is incorrect
