Carlos is saving money to buy a set of golf clubs that cost $530. He already has $80.00 saved and can earn the rest of the money by mowing 15
lawns. If m represents how much he earns for mowing each lawn, which of the following equations can be solved to find how much Carlos is paid for
mowing each lawn?
Answer:
15m+80 would be the correct equation
Answer:
15*m=(530-80)
Step-by-step explanation:
30$ per lawn. 530-80=450. This gives us how much money he still needs to buy his gulf clubs. But, the question says that Carlos can earn the rest of the money ($450) by mowing 15 lawns.
Here's how we model that as an expression:
15m=(530-80)
15 lawns for m dollars would get him 530-80 (450) or the remaining amount.

Un padre tiene actualmente cuatro veces la edad de su hijo. Cuando pasen 5 años, su edad será solo tres veces superior. ¿Qué edad tiene cada uno?
Answer:
I. Hijo, h = 10 años
II. Padre, P = 40 años
Step-by-step explanation:
Sea la edad del padre P. Sea la edad del hijo h.Traduciendo el problema verbal a una expresión algebraica, tenemos;
P = 4h .....ecuación 1.
P + 5 = 3(h + 5) ........ecuación 2.
Simplificando aún más, tenemos;
P + 5 = 3h + 15
P = 3h + 15 - 5
F = 3h + 10 ......ecuación 3.
Sustituyendo la ecuación 1 en la ecuación 3;
4h = 3h + 10
4h - 3h = 10
h = 10 años
A continuación, encontraríamos la edad del padre;
P = 4h
P = 4 * 10
P = 40 años
What is the equation of the line that is parallel to the given line and passes theought the point (12, -2)
Y= -6/5x + 10
Y= -6/5x + 12
Y= -5/6x - 10
Y= 5/6x - 12
Answer:
Option D (y = 5/6x -12).
Step-by-step explanation:
Hey there!
The equation of the line which passes through the point (12,-2) is (y+2) = m2(x-12)………(i) [Using one point formula].
According to the question, the first line passes through point (12,6) and (0,-4).
So,
[tex]slope(m1) = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]or \: m1 = \frac{ - 4 - 6}{0 - 12} [/tex]
[tex]or \: m1 = \frac{5}{6} [/tex]
Therefore, the slope of the line is 5/6.
Now as per the condition of parallel lines, m1 =m2 = 5/6.
So, keeping the value of m2 in equation (i), we get;
(y+2) = 5/6(x-12)
[tex]y + 2 = \frac{5}{6} x - 10[/tex]
or, y = 5/6x - 12.
Therefore, the required equation is y = 5/6 X - 12.

What are the vertices of triangle A'B'C' if triangle ABC is dilated by a scale factor of 1/4
A ' (4,0)
B ' (6,3)
C ' (3,4)
================================================
Explanation:
I'm assuming the center of dilation is the origin.
If so, then we multiply the scale factor 1/4 = 0.25 by each of the coordinates of the three points.
Point A(16,0) will move to A ' (4,0) since
16*0.25 = 40*0.25 = 0Point B(24,12) will move to B ' (6,3) since
24*0.25 = 612*0.25 = 3We have enough information to see that choice B is the final answer
If you wanted to keep going, then point C(12,16) will move to C ' (3,4) for similar reasoning/steps as the previous two points.
The resulting image triangle A'B'C' will have its side lengths 1/4 of that compared to the side lengths of the preimage triangle ABC.
The scale factor k is such that 0 < k < 1, which indicates the image will be smaller compared to the preimage. If k > 1, then the image would have been larger than the preimage.

Answer:
2*(5x+4) + 2*(3x+2)
= 10x + 8 + 6x + 2
= 16x + 10
The perimeter of the rectangle, in feet, is represented by (16x + 10)
Answer:
(16x + 12) ft
Step-by-step explanation:
Perimeter of the rectangle = 5x + 4 + 3x + 2 + 5x + 4 + 3x + 2
Perimeter of the rectangle = (16x + 12) ft
The speed of the water in a whirlpoil varies inversely with the radius. if the water speed is 2.5 feet per second at a radius of 30 feet what js the speed of the water at a radius of 3 feet?
Answer:
25 feet per second.
Step-by-step explanation:
Let s represent the speed of the water and r represent the radius of the whirlpool.
The speed in a whirlpool varies inversely with the radius. Therefore, we can write that:
[tex]\displaystyle s=\frac{k}{r}[/tex]
Where k is the constant of variation.
We know that the speed is 2.5 feet per second when the radius is 30 feet.
So, s = 2.5 when r = 30. Substitute:
[tex]\displaystyle 2.5=\frac{k}{30}[/tex]
Solve for k:
[tex]k=30(2.5)=75[/tex]
So, our equation is:
[tex]\displaystyle s=\frac{75}{r}[/tex]
Then when the radius is three feet, r = 3. Evaluate for s:
[tex]\displaystyle s=\frac{75}{(3)}=25\text{ feet per second}[/tex]
So, the speed of the water in a whirlpool with a radius of three feet is 25 feet per second.

Which relation is a function?
A. (8,-4), (8,4), (6,-3), (6,3), (0, 0)
B. (4, 7), (8,5), (6,4), (5, 3), (4, 2)
C. (0, 0), (1, 1), (2, 2), (3, 3), (4,7)
D. (0, 0). (1, 0), (1, 1), (2, 1), (1, 2)
To determine which relation is a function, we need to check if each input value (x) corresponds to a unique output value (y). If there is any repetition in the x-values, then it is not a function. in option (0, 0), (1, 1), (2, 2), (3, 3), (4,7) no repetition x-values so c is correct.
Let's analyze each option:
A. (8,-4), (8,4), (6,-3), (6,3), (0, 0)
In this relation, we can see that both 8 and 6 have repeated as x-values. Therefore, option A is not a function.
B. (4, 7), (8,5), (6,4), (5, 3), (4, 2)
Again, we notice that 4 appears twice as an x-value. Hence, option B is not a function.
C. (0, 0), (1, 1), (2, 2), (3, 3), (4,7)
Here, each x-value is unique. No repetition is observed. Therefore, option C represents a function.
D. (0, 0). (1, 0), (1, 1), (2, 1), (1, 2)
In this relation, the x-value of 1 appears three times. Consequently, option D is not a function.
To summarize, option C is the only relation that represents a function since it has distinct x-values corresponding to unique y-values.
Option C is correct answer

What is the radius of a sphere with a volume of 41572 cm', to the nearest tenth of a
centimeter?
We know that,
Volume of sphere = 4/3πr³
41572 = 4/3 × 22/7 × r³
41573 × 21/88 = r³
³√9,920.82 = r
21.48 cm = r
:)
The radius of a sphere with a volume of 41572 cm³ is,
⇒ 21.4 cm
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Now, To find the radius of a sphere with a volume of 41572 cm³, we can use the formula for the volume of a sphere as;
⇒ V = (4/3)πr³
where V is the volume and r is the radius.
Hence, We can rearrange this formula to solve for r:
⇒ r = ∛ (3V/4π)
Substituting the given volume, we have:
r = ∛ (3(41572)/4π)
r ≈ 21.4 cm
Therefore, the radius of the sphere to the nearest tenth of a centimeter is 21.4 cm.

Find the area of this semi-circle with radius, r = 6cm.
Give your answer as an expression in terms of pi
Answer:
72π (I think)
Step-by-step explanation:
Think of it in terms of the entire circle. A semi-circle is just half a circle, so the area of a semicircle will be half of the area of the entire circle. The radius of the semicircle is 6, so the radius of the whole circle is 12. Then, we can do [tex]\frac{pi*r^{2} }{2}[/tex] to get the area of the semicircle is 72π. I'm pretty sure that's right.
