9^2 + 12^2= c^2
81 + 144 = 225
C= 15
The answer is 15 yards.
Answer:
Hi there!
The correct answer will be 15 yd
Step-by-step explanation:
There are two ways you can go about solving this problem
Method One: Pythagorean Theorem
a^2 + b^2 = c^2 then all you have to do is plug in the values
(12)^2 + (9)^2 = c^2 you should get c^2 = 225 then you square root both sides and you get c = 15
Method Two: Pythagorean Identities
This triangle represents a 3,4,5 triangle
All the sides just tripled so that means the hypotenuse is 5*3 which equals 15

Write an equation that represents the volume V as a function of the height h
Answers
Answer:
h=V/b
Step-by-step explanation:
The volume V can be represented as a function of height h by the equations V = lwh for a rectangular prism or V = πr²h for a cylinder. If other dimensions are constants, this can be simplified to V=k*h, where k represents the base area.
Explanation:To represent the volume V as a function of the height h, we typically consider the volume of a rectangular or cylindrical shape. The volume V of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height. If we consider a cylinder, the volume is given by the equation V = πr²h, where r is the radius of the base circle and h is the height. However, if we simplify this formula assuming only the height can vary and all other dimensions are constants, the function could be simplified to V=k*h, where k represents the area of the base.

8. - 6x + 14 <-28 OR 9x + 15 <- 12
Answers
For this case we must indicate the solution set of the given inequalities:
[tex]-6x + 14 <-28[/tex]
Subtracting 14 from both sides of the inequality we have:
[tex]-6x <-28-14\\-6x <-42[/tex]
Dividing by 6 on both sides of the inequality:
[tex]-x <- \frac {42} {6}\\-x <-7[/tex]
We multiply by -1 on both sides, taking into account that the sense of inequality changes:
[tex]x> 7[/tex]
Thus, the solution is given by all values of x greater than 7.
On the other hand we have:
[tex]9x + 15 <-12[/tex]
Subtracting 15 from both sides of the inequality we have:

At the zoo, the ratio of mammals to reptiles is 4:3. There are 20 mammals in the zoo.
(a) How many reptiles are in the zoo?
(b) If the zoo adds 12 more mammals to its collection, how many more reptiles will they have to add to keep the ratio the same?
(c) A zoo in a different city has a ratio of mammals to reptiles of 6:5. Which zoo has the larger ratio of mammals to reptiles?
Thank you!
Answers
Answer: im not sure but a)15 B)24 c)zoo in a different city
Step-by-step explanation:
There are 15 reptiles in the zoo. To keep the ratio 4:3, if the zoo adds 12 more mammals, they will need to add 9 more reptiles. The first zoo has a larger ratio of mammals to reptiles (4:3) compared to the second zoo (6:5).
To answer the question, let's solve each part step by step:
Given the ratio of mammals to reptiles is 4:3 and there are 20 mammals, we can set up a proportion to find the number of reptilesIf the zoo adds 12 more mammals, to keep the same ratio of 4:3, we calculate the number of reptiles to add. We can find this by multiplying the 12 additional mammals by 3/4, which results in 9 more reptiles.To compare the ratios of the zoos, we can turn them into comparable fractions: 4/3 for the first zoo and 6/5 for the second zoo. By finding a common denominator or comparing their cross-multiplication products, we can determine which ratio represents a larger number of mammals to reptiles. Here, 4/3 is larger than 6/5, so the first zoo has a larger ratio of mammals to reptiles. This can be confirmed by cross multiplication: 4*5=20 and 6*3=18, since 20 is greater than 18, the first zoo has a larger ratio.Find the value of 6+x when x = 15.
Answers
Answer:
Step-by-step explanation:
Given the function f(x)=6+x
F(x) is dependent on x,
When x=1
f(x)=6+x
f(x)=6+1,
f(x)=7
When x=2
f(x)=6+x
f(x)=6+2
f(x)=8.
This will continue like this till we get to x=15
So when x=15
We will substitute x=15 into the function f(x)
f(x)=6+x
f(x)=6+15
f(x)=21
Then, the answer is 21.
Answer: 17

Calculate the length of AB using Sine rule
Answers
Answer:
Approximately [tex]22.2\; \rm m[/tex].
Step-by-step explanation:
By sine rule, the length of each side of a triangle is proportional to the sine value of the angle opposite to that side. For example, in this triangle [tex]\triangle ABC[/tex], angle [tex]\angle A[/tex] is opposite to side [tex]BC[/tex], while [tex]\angle C[/tex] is opposite to side [tex]AB[/tex]. By sine rule, [tex]\displaystyle \frac{BC}{\sin{\angle A}} = \frac{AB}{\sin \angle C}[/tex].
It is already given that [tex]BC = 22.4\; \rm m[/tex] and [tex]\angle A = 58^\circ[/tex]. The catch is that the value of [tex]\angle C[/tex] needs to be calculated from [tex]\angle A[/tex] and [tex]\angle B[/tex].
The sum of the three internal angles of a triangle is [tex]180^\circ[/tex]. In [tex]\triangle ABC[/tex], that means [tex]\angle A + \angle B + \angle C = 180^\circ[/tex]. Hence,
[tex]\begin{aligned}\angle C &= 180^\circ - \angle A - \angle B \\ &= 180^\circ - 58^\circ - 65^\circ \\ &= 57^\circ\end{aligned}[/tex].
Apply the sine rule:
[tex]\begin{aligned} & \frac{BC}{\sin{\angle A}} = \frac{AB}{\sin \angle C} \\ \implies & AB = \frac{BC}{\sin{\angle A}} \cdot \sin \angle C \end{aligned}[/tex].
[tex]\begin{aligned}AB &= \frac{BC}{\sin{\angle A}} \cdot \sin \angle C \\ &= \frac{22.4\; \rm m}{\sin 58^\circ} \times \sin 57^\circ \\ &\approx 22.2\; \rm m\end{aligned}[/tex].

Karla had $138.72 in her checking account. She wrote checks for $45.23 and $18. Then she made a deposit for 75.85 into her account.what is the best estimate for how much money is in karla’s account now
Answers
Answer:
$151.34
Step-by-step explanation:
First, Karla starts with $138.72.
Then Karla writes checks for $45.23 and $18.00. This means the money will be withdrawn, so let's subtract these from the total.
$138.72 - $45.23 - $18.00 = $75.49
Now, Karla has $75.49 in her account.
However, a $75.85 deposit is made to her account. So let's add this back to the total.
$75.49 + $75.85 = $151.34
So after all the transactions, Karla has $151.34 in her checking account.
LaTanya says that the growth factor of f(x) = 100(1.25) is 25%. What mistake did LaTanya make?
Answers
Answer:
The first error consists in the multiplication of f (x) = 100 * (1.25), the value she mentions is incorrect since it is 125.
It would be a 125% increase really.
In order for LaTanya's phrase to have no error she had to mention that it was a 25% increase over the original amount, in this way, the phrase would make sense and be valid.
Answer:
LaTanya confused growth factor with growth rate. The growth factor is 1.25. The growth rate is 25%.
Step-by-step explanation:
In the exponential growth model,
f(x)=a(1+r)x
a is the inital amount, r is the growth rate, and (1+r) is the growth factor. Hence, the growth factor of the given function is 1.25.
The lengths of the three sides of a triangle are given. Classify each triangle as acute, right or
obtuse.
30, 40, 50
1)
Answers
Triangle with side lengths 30, 40, and 50 is a right triangle.
To classify the triangle based on the lengths of its sides, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
For the given lengths of sides:
[tex]\(a = 30\)[/tex]
[tex]\(b = 40\)[/tex]
[tex]\(c = 50\)[/tex]
We can check if the triangle is a right triangle:
[tex]\[c^2 = a^2 + b^2\][/tex]
Substituting the values:
[tex]\[50^2 = 30^2 + 40^2\][/tex]
[tex]\[2500 = 900 + 1600\][/tex]
[tex]\[2500 = 2500\][/tex]
Since [tex]\(2500 = 2500\)[/tex], the Pythagorean theorem holds true, meaning this triangle is a right triangle.
So, the given triangle with side lengths 30, 40, and 50 is a right triangle.

5y-4x =-7 Equation 1
2y+4x=14 Equation 2
Since x has the same coefficient, it's easy to eliminate by adding up the two equations
5y+2y=7y
-4x+(+4x)=0
-7+(+14)=7
We have 7y=7
Divide both sides by 7,
y=7/7
y=1
Substituting for y in equation 2.
2(1)+4x=14
2+4x=14
4x=14-2
4x=12

What is the inverse of f(x)= 9x-8
Answers
Answer:
f^-1(x) = (x + 8) / 9
Step-by-step explanation:
Step 1: Set y to x and x to y
y = 9x - 8
x = 9y - 8
Step 2: Solve for y
x + 8 = 9y - 8 + 8
(x + 8) / 9 = 9y / 9
(x + 8) / 9 = y
Step 3: Rename y to f^-1(x)
f^-1(x) = (x + 8) / 9
Answer: f^-1(x) = (x + 8) / 9
The inverse of the function f(x) = 9x - 8 is f^-1(x) = (x + 8) / 9.
To find the inverse of the function f(x) = 9x - 8, follow these steps:
First, replace f(x) with y. So, we have y = 9x - 8.
Next, solve for x. To do this, swap x and y to get x = 9y - 8.
Now, isolate y by adding 8 to both sides, resulting in x + 8 = 9y.
Finally, divide both sides by 9 to solve for y, giving y = (x + 8) / 9. This is the inverse function.
To denote the inverse, we replace y with f-1(x), resulting in f-1(x) = (x + 8) / 9.
