Answer:
[tex]\frac{10}{43}[/tex] acres
Step-by-step explanation:
Divide 10 by 43:
10/43
In simplest form as a fraction, this is [tex]\frac{10}{43}[/tex]
So, each section would have [tex]\frac{10}{43}[/tex] acres

Step-by-step explanation:
The distributive property of multiplication states that [tex]a(b+c)=a*b+a*c[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are any real numbers. In the case of [tex]4(x+1)[/tex], we know that [tex]a=4[/tex], [tex]b=x[/tex], and [tex]c=1[/tex]. Therefore, using the distributive property, [tex]4(x+1)=4*x+4*1=4x+4[/tex]. Hope this helps!

Step-by-step explanation:
Steph makes 90\%90%90, percent of the free throws she attempts. She is going to shoot 333 free throws. Assume that the results of free throws are independent from each other. Let XXX represent the number of free throws she makes.
Find the probability that Steph makes exactly 111 of the 333 free throws.
Using the concept of binomial probability, the probability of making exactly 11 throws is [tex]6.073 \times 10^{-15} [/tex]
Recall :
P(x = x) = nCx * p^x * q^(n-x)p = probability of success = 0.9n = number of trials = 33q = 1 - p = 0.1The probability of making exactly 11 throws can be defined thus :
P(X = 11) = 33C11 * 0.9^11 * 0.1^22Using a binomial probability calculator :
P(X = 11) = [tex]6.073 \times 10^{-15} [/tex]
Therefore, the probability is [tex]6.073 \times 10^{-15} [/tex]

Answer/Step-by-step explanation:
Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².
We would use the above knowledge to solve the questions given as follows:
✔️The first pair similar of shapes:
Missing area = x cm²
Therefore,
x/9 = 8²/4²
x/9 = 64/16
x/9 = 4
Cross multiply
x = 4 × 9
x = 36 cm²
✔️The second pair similar of shapes:
Missing area = x cm²
Therefore,
x/240 = 8²/32²
x/240 = 64/1,024
Cross multiply
x*1,024 = 64*240
x*1,024 = 15,360
Divide both sides by 1,024
x = 15,360/1,024
x = 15 cm²
✔️The third pair similar of shapes:
Missing area = x cm²
Therefore,
x/40 = 3²/2²
x/40 = 9/4
Cross multiply
x*4 = 9*40
x*4 = 360
Divide both sides by 4
x = 360/4
x = 90 cm²
Use the table to find the ratio. Enter the ratio as a fraction in simplest form.

In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. what is the probability in simplest form of a yellow marble being selected on the first draw.
Answer:
The probability is 1/3, or in percent form, 33.3%.
Step-by-step explanation:
First, add up all the marbles. 3 plus 2 plus 1 equals 6 total marbles.
There are 2 yellow marbles out of 6 total marbles. Make it a fraction: 2/6.
Simplify the fraction by dividing by 2, to get 1/3, which is 33.3%.

3 coins are tossed and two six sided dice are rolled what is the probablity of getting 3 heads. and an even number on the dice show your work for brainliest if its correct.
Answer:
1/32
Step-by-step explanation:
- if the even numvers of the every six-sided dice are: 2; 4; 6, then the probability of even number of one dice is 3/6=0.5.
- the probability of getting head of one coin is 0.5;
- the required probability of getting 3 heads and even number on the dice is:
0.5^³*0.5^²=0.125*0.25=0.03125 (or 1/32)

Solve for x.
x=
Look at image
Answer:
[tex] x = 14 [/tex]
Step-by-step explanation:
To find x, the following equation is generated given the available information:
[tex] \frac{(x + 7) + x)}{x + 7} = \frac{12 + 8}{12} [/tex]
[tex] \frac{2x + 7}{x + 7} = \frac{20}{12} [/tex]
[tex] \frac{2x + 7}{x + 7} = \frac{5}{3} [/tex]
Cross multiply
[tex] 3(2x + 7) = 5(x + 7) [/tex]
[tex] 6x + 21 = 5x + 35 [/tex]
Collect like terms
[tex] 6x - 5x = - 21 + 35 [/tex]
[tex] x = - 21 + 35 [/tex]
[tex] x = 14 [/tex]

Answer:
as the two lines are parallel to one another, they do not intersect (connect) at any point. therefore there is no solution and it is an INCONSISTENT SYSTEM.
Step-by-step explanation:
homogenuos function who can solve it
Answer:
a) f(x) is a homogenous function of degree '1'
b) f(x) is a homogenous function of degree '2'
Step-by-step explanation:
Step(i):-
Homogenous function
If f(x) is a homogenous function of degree 'n' then
[tex]f(k x ,k y) = k^{n} f(x, y)[/tex]
a)
Given [tex]f(x, y) = \sqrt{x^{2} +3xy+2y^{2} }[/tex]
[tex]f(kx, ky) = \sqrt{(kx)^{2} +3kx(ky)+2(ky)^{2} }[/tex]
[tex]f(kx, ky) = \sqrt{(k)^{2} (x)^{2} +3k^{2} (xy)+2(k)^{2} y^{2} }[/tex]
[tex]f(kx, ky) =( k^{2})^{\frac{1}{2} } ( \sqrt{(x)^{2} +3 (xy)+2 y^{2} })[/tex]
f( k x , k y ) = k f( x, y)
∴ f(x) is a homogenous function of degree '1'
Step(ii):-
b)
[tex]f(x, y) = \sqrt{x^{4} +3x^{2} y+5y^{2} x^{2} -2y^{4} }[/tex]
[tex]f(kx, ky) = \sqrt{(k x)^{4} +3(k x)^{2} y+5(k y)^{2} (k x)^{2} -2(k y)^{4} }[/tex]
[tex]f(kx, ky) = (k^{4})^{\frac{1}{2} } \sqrt{( x)^{4} +3( x)^{3} y+5( y)^{2} ( x)^{2} -2( y)^{4} }[/tex]
f(k x , k y ) = k² f( x , y )
∴ f(x) is a homogenous function of degree '2'
Examine the following table. Determine whether the rate of change is constant or variable. If it is constant, state the rate of change.
Answer:
Variable rate of change.
Step-by-step explanation:
Plot the points and you'll see that the graph is not a straight line, therefore the rate of change is variable.
Rate of change is variable in the given data.
What is variable?"Variable is a quantity which shows the change in value as per the conditions apply on it."
What is rate of change?"Rate of change is defined as when there is a change in one quantity or variable with respect to another quantity or variable."
According to the question,
Change in time interval is constant with the difference of 1 second.
Change in distance is vary as time increases.
From the graph we can conclude the rate of change is not constant as graph is not a straight line.
Hence, rate of change is variable in the given data.
