Two similar figures have a scale factor of 4/3.
If one side of the smaller figure is 12. determine size of the side of the
corresponding side in the larger figure.
9
16
40/3
32/3
Answers
Answer:
This is the concept of scale factors; The length of the larger figure will be calculated as follows;
linear scale factor=[length of larger figure]/[length of smaller figure]
plugging the values in the above formula we get:
let the length of the larger figure be x;
thus;
x/12=4/3
multiplying both sides by 12 to solve for x we get:
12*x/12=4/3x12
x=16
thus the length of the larger figure is x=16
Answer:16
Step-by-step explanation:
12 times 4/3 is 4^2 or 16
and are independent Gaussian (Normal) random Variables. has mean 13.9 and variance 5.2; has mean 6.9 and variance 3.8. . (a) Calculate
Answers
This question is incomplete, the complete question is;
X and Y are independent Gaussian (Normal) random Variables. X has mean 13.9 and variance 5.2; Y has mean 6.9 and variance 3.8. . (a) Calculate P( W> 10)
Answer:
P( W> 10) is 0.1587
Step-by-step explanation:
Given that;
X ⇒ N( 13.9, 5.2 )
Y ⇒ N( 6.9, 3.8 )
W = X - Y
Therefore
E(W) = E(X) - E(Y)
= 13.9 - 6.9 = 7
Var(W) = Var(X) + Var(Y) -2COV(X.Y)
[ COV(X,Y) = 0 because they are independent]
Var(W) = 5.2 + 3.8 + 0
= 9
Therefore
W ⇒ N( 7, 9 )
so
P( W > 10 )
= 1 - P( W ≤ 10 )
= 1 - P( W-7 /3 ≤ 10-7 /3 )
= 1 - P( Z ≤ 1 ) [ Z = W-7 / 3 ⇒ N(0, 1) ]
from Standard normal distribution table, P( Z ≤ 1 ) = 0.8413
so
1 - P( Z ≤ 1 ) = 1 - 0.8413 = 0.1587
Therefore P( W> 10) is 0.1587

PLEASEEE HELP ! I WOULD APPRECIATE IT VERY MUCH :)

hi!
so the original equation is (x^2 -121) / x+ 11.
Those two equations look similar...
well, we know that the top equation looks like a^2 - b^2, and that equation iis equivalent to this equation: (a+b)(a-b).
So if we factor that out, we get:
( (x + 11) * (x-11) )/ (x + 11)
we can cancel the x+11 on the top and the x+11 on the bottom out.
that leaves us with x-11.
Hope this helped!
book is 6 inches wide and 9 inches tall. A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. A publisher wants to use a scale factor of 1.5 to enlarge a book. What will the area of the front of the book be after the book is enlarged? 54 in2 81 in2 121.5 in2 78.75 in2
Answers
Answer:
6x1.5=9
9x1.5=13.5
9x13.5=121.5
Step-by-step explanation:
Answer: 121.5 in²
Step-by-step explanation: If you multiply the width (6 in.) by 1.5 to scale is up you get 9 in. and if you do the same with the length (9 in.) you get 13.5 in. ... You can then calculate the area.
Round 4,287,965 to the nearest thousand
Answers
Answer:
It is 4,288,000.
Step-by-step explanation:
To round to the nearest thousand, you need to find the thousands place. In the thousands place there is a "7". Okay, we've found it, so the next step is rounding.
To round, there is a handing phrase that we can use to know whether we should round the place up or down. It is "4 or less, let it rest. 5 or more, add 1 more." We need to apply this phrase to the number behind the place we need to round (so apply it to the place behind the thousands place).
When we look behind the thousands place, we see there is a 9. Apply the rule to that. Since 9 is above 5 and not less than 4, we need to add one more to the thousands place.
That means after we round, the 7 turns into a 8. That's how you get 4,288,000.
Hope this makes sense <3

2) A farmhouse shelters 61 animals. Some are cows and some are ducks. Altogether there are
208 legs. How many of each animal are there?
Answers
43 cows and 18 ducks
Explanation:
Let c represent the number of cows in the farmhouse.
Let d represent the number of ducks in the farmhouse.
We know that:
- there are a total of 61 animals in the farmhouse
- one cow has 4 legs
- one duck has 2 legs
- there are a total of 208 legs
Using the information above, we can create two equations:
c+d=61
4c+2d=208
1) multiply the first equation by 2
If we do this, both equations will have 2d and we can subtract them to solve for c.
c+d=61
2c+2d=122
2) Subtract the first equation from the second
4c+2d=208
2c+2d=122
2c=86
c=43
Therefore, the number of cows in the farmhouse is equal to 43.
2) plug 43 into the first equation to solve for d
We can plug 43 into either of the original questions to find the number of ducks, but in this case, it would be easier to solve for in the first equation.
c+d=61
43+d=61
Subtract both sides by 43
43+d-43=61-43
d=18
Therefore, the number of ducks in the farmhouse is equal to 18.

4 < x < 9 x is an interger, write down all the possible values of x
Answers
Answer:
The possibel values of x is 5, 6, 7, 8.
Step-by-step explanation:
Integer is a positive or negative whole number.
In this case, x must be positive and it have to be greater than 4 but smaller than 9 so the possible values will be 5, 6, 7 and 8.
It says [tex]x[/tex] is greater than [tex]4[/tex] and it is less than [tex]9[/tex]
The first value which is greater than [tex]4[/tex] is [tex]5[/tex] and the value which is less than [tex]9[/tex] is [tex]8[/tex]. So the answer would be all integers from [tex]5[/tex] to [tex]8[/tex] (inclusive)
[tex]5, 6, 7, 8[/tex] would be the answer! :D

Step-by-step explanation:
It is convenient to write the proportion with the unknown (width) on top:
width/length = 4/9 = w/(18 cm)
Multiplying by 18 cm gives ...
w = (18 cm)(4/9) = 8 cm
The width of the rectangle is 8 cm.

Answers
Answer:
7r-8
Step-by-step explanation:
yout are the two common factors in this case they are 8r and -r which is also -1r and put them in an equation and you di the same for +6 and -14
Firstly we will solve -1r +8r
+8r overpowers -1r so we will use the positive sign for this one. 8-1 is 7 and I we use the positive sign from the overpowered number you get 7r
Now we move on to +6-14
this is just simple addition and subtraction
what is 14-6 it is -8
-14 overpower 6 so we use its sign
Lastly we put it all together and get
7r - 6
