Naomi's fish is 40 millimeters long. Her guinea pig is 25 centimeters long.
How much longer is her guinea pig than her fish?
Answer:
21cm
Step-by-step explanation:
Solution,
Length of fish=40mm=40/10=4cm
Length of pig=25cm
Now,
Difference of their length=25cm-4cm=21cm
Hence,the pig is 21cm long than the fish

Answer :
[tex] \orange{ \boxed{ \pink{ {x}^{2} - 9}}}[/tex]
Step-by-step explanation :
We can use the formula that :
(a + b) (a - b) = a(a - b ) + b(a - b)
= a² - ab + ab - b² = a² - b²
_________________________
(x + 3) (x - 3)
We have :
a = x
b = 3
So :
( x + 3 ) ( x - 3 )
x (x - 3 ) + 3 (x - 3 )
x² - 3x + 3x - 9
x² - 9
Answer = x² - 9

The variance of a distribution is the square of the standard deviation
The variance of the data is 9
How to determine the varianceThe given parameters are:
Mean = 9 cars
Distribution type = Poisson distribution
The variance and the mean of a Poisson distribution are equal.
So, we have:
Variance = 9 cars
Hence, the variance of the data is 9

Answer:
f ( x ) = ( x - 5 ) ² - 20
Step-by-step explanation:
1- Add the same value to both sides
f ( x ) = x ² - 10x + 5
2- Add 25 to the expression
f ( x ) + ? = x ² - 10x + ? + 5
3- Add 25 to the left-hand side
f ( x ) + ? = x ² - 10x + 25 + 5
4- Factor the expression
f ( x ) + 25 = x ² - 10x + 25 + 5
5- Move the constant to the right
f ( x ) + 25 = ( x - 5 ) ² + 5
6- Calculate
f ( x ) = ( x - 5) ² + 5 - 25

Answer:
1.15
Step-by-step explanation:
Answer:
1.15
Step-by-step explanation:
So, first it would be helpful to change this from an improper fraction to a mixed number. Because we have an improper fraction now, we need to make this a mixed number by seeing how many times 23 can go into 20. Twenty-three can't go into 20, but if we take away 3 from 23 it can.
So, now we have 20/20 but with a remainder of 3/20. Because 20/20 = 1, it becomes a whole number of 1 and 3/20. Because there is a whole number of 1, we can put this as the whole number for the decimal. The fraction 3/20 is equal to the decimal 0.15, so we can now put the decimal together now that we have all the parts for the answer needed, which is 1.15.

answer to the nearest whole number if necessary.
Answer:
85%
-> If 34 of the 40 exhibits are lions, then 34/40 are lions.
-> 34/40 = 0.85
-> 0.85 * 100 = 85%

Answer:
We want to multiply two polynomials of degree 1, and get in that way a polynomial of degree 2.
We will get the polynomial: p(x) = 2 * x² + 2 * x - 12
Step-by-step explanation:
We just want to multiply (x + 3) and (2*x - 4).
So we start by writing:
(x+3) * (2*x-4)
Now we just expand this:
(x+3) * (2*x-4) = 2 * x² + x * (-4) + 3 * (2 * x) + 3 * (-4)
Now we need to simplify the above expression:
2 * x² + x * (-4) + 3 * (2*x) + 3 * (-4) = 2 * x² + (6 - 4) * x - 12 = 2 * x ² + 2 * x - 12
This is the polynomial we wanted to get:
p (x) = 2 * x² + 2 * x - 12

Answer:
x-intercept = 3/4
y-intercept = -3
Step-by-step explanation:
4x - y = 3 (Given)
To find x-intercept plug y = 0 in the given equation.
4x - 0 = 3
4x = 3
x = 3/4
To find y-intercept plug x = 0 in the given equation.
4(0) - y = 3
0 - y = 3
- y = 3
y = -3
Use < , > , = , ≤ , ≥ to complete these statements. 1) if x < y , then y___ x, 2) if x > 5 and 5 > y, then x ___ y, 3) if x is four at most, then x ___ 4, 4) if x - y = 0, then x ___ y Can someone please help me I've been stuck on these for 3 days.
Answer:
1) y > x
2) x > 5 > y
3) x ≤ 4 ( or 4 ≥ x )
4) x = y
Step-by-step explanation:
1) 1. y is greater than x
2. so y > x
2) 1. 5 is less than x and more than y
2. we can write this like x > 5 > y
3. you can just squish them together as a shortcut usually: x > 5 and 5 > y --> x > 5 > y
3) 1. x is for at most, we can say this as x is less than or equal to 4
2. this is written as x ≤ 4 or 4 ≥ x
4) 1. x - y = 0 so x and y must be the same value
2. therefore x = y
What’s the correct answer for this question?
Answer:
9.6 acres
Step-by-step explanation:
First we have to change the yards to feet. 1 yd = 3 ft.
173 yds x 3 = 519 ft
269 yds x 3 = 807 ft
From here, use a calculator if you don't wan't to stress yourself.
807 x 519 = 418833
418833/43560 = 9.61508264463 ≈ 9.6
