Answer:
Sophie has to work 18 hours to buy the sneakers.
Step-by-step explanation:
Since Sophie earns $ 12.80 per hour babysitting, and she has to repay a loan to her parents in the amount of $ 100, and after repaying the loan, she wants to have at least enough money to buy herself a pair of sneakers costing $ 130.40, for write an inequality modeling the number of hours, X, Sophie needs to work to have enough money to buy the sneakers, the following mathematical reasoning must be carried out:
12.80X = 100 + 130.40
12.80X = 230.4
X = 230.4 / 12.8
X = 18
So Sophie has to work 18 hours to buy the sneakers.

What is the measure of the angle of the hands on a clock if it is 3:24?
Answer:
from 3 o’clock until 3:20, the minute hand will move 1/3 of the way around the circle or 120 degrees. But the hour hand has also moved 1/3 of the way to the next number, or 10 degrees.
Answer:
42deg
Step-by-step explanation:
Let's see.
We'll consider 12:00 the "starting position"
The minute hand moves with the speed of 360deg in an hour, so 6deg per minute.
The hour hand moves with the speed of 360deg in 12hours, so 30deg per hour, so 0.5deg per minute.
at 3:24, the minute hand has moved 24*6deg=144deg from the starting position, while the hour hand has moved by 3*30deg + 24*0.5deg = 102deg
The absolute difference of the angles is 144deg-102deg = 42deg and it's the angle between the hands.
Help me with this please. thanks.
Answer:
Step-by-step explanation:
It's linear.
First of all, let's recreate the table.
The equa ttion is something like
y = a x
Now if x = - 9
and y = - 157 / 3
Then a = -157/ (-9*3)
a = 5.814814814....
y = 5.814814 (-8)
y = - 46.5185185....
y = -139/3 = -46.333333333 the difference is in how this was rounded.
y = 5.814814 * -7 = 40.703703703...
y = -121/3 = -40.333333 Again another rounding problem.
I'm sure if you try the rest of them, they will do the same thing.

Find the radius of a circle with a circumference of 23.55 feet. Use 3.14 for
Answer:
3.75
Step-by-step explanation:
The radius of the circle will be (11.775/π).
What is the area of a circle? What is an exponential function? Differentiate between equation and expression? area of circle : The area of a circle is equivalent to -[A] = πr² = πd²/4
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the circumferance of the circle is 23.55 feet.
We can write -
2πr = 23.55
r = (23.55/2π)
So, the area of the circle will be -
{A} = πr²
{A} = π x (23.55 x 23.55)/4π²
{A} = (555/4π)
{A} = 138.75/π
r = (23.55/2π)
r = (11.775/π)
Therefore, the radius of the circle will be (11.775/π).

What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
Given a graph.
It has a solid line and a dotted line.
The given equation is, y = 4ˣ.
In order to find which graph shows the equation, find the points that the graph of the equation will pass through.
When x = 0, y = 4⁰ = 1
Solid graph passes through (0, 1).
Hence Mark is correct.

determine the angle of rotation
a. -105
b. -75
c. 75
d. 105
9514 1404 393
Answer:
b. -75°
Step-by-step explanation:
Point A moves from (-4, -3) to (-4, 3). We can find the angle of rotation several ways. One is to consider the tangent of the angle relative to the x-axis.
Point A is on a line that makes an angle to the x-axis of ...
∠A = arctan(-3/-4) = 36.9°
Point A' is on a line that makes an angle to the x-axis of ...
∠A' = arctan(3/-4) = -36.9°
Then the change in angle is ...
∠A' -∠A = -36.9° -36.9° = -73.8°
The closest answer choice is ...
b. -75°

What is the 7th term in the sequence?
Answer:
[tex]T_7 = 136.6875[/tex]
Step-by-step explanation:
Given
12, 18, 27, ..
Required
Determine the 7th term
The above sequence shows a geometric sequence and the nth term is calculated by:
[tex]T_n = a * r^{n-1[/tex]
r is calculated by:
[tex]r = \frac{T_2}{T_1}[/tex]
[tex]r = \frac{18}{12}[/tex]
[tex]r = 1.5[/tex]
[tex]a = 12[/tex] --- First term
[tex]n = 7[/tex]
So:
[tex]T_n = a * r^{n-1}[/tex]
[tex]T_7 = 12 * 1.5^{7-1[/tex]
[tex]T_7 = 12 * 1.5^6[/tex]

35. Para pintar una casa se mezclaron 5/4 L do pintura blanca y 1/2 L de pintura azul. Al final solo se emplearon 213 L de la mezda,
¿cuántos litros de pintura sobraron?
Answer:
Total paint left over = [tex]\frac{13}{12}L[/tex]
Step-by-step explanation:
Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint
were mixed. In the end only 2/3 L of the mixture were used.
To find - How many liters of paint were left over ?
Proof -
Given that,
5/4 L of white paint and 1/2 L of blue paint were mixed.
So, total mixture = [tex](\frac{5}{4} + \frac{1}{2})L[/tex]
= [tex]\frac{5 + 2}{4}L[/tex]
= [tex]\frac{7}{4}L[/tex]
⇒Total mixture = [tex]\frac{7}{4}L[/tex]
Now,
Given that ,
In the end only 2/3 L of the mixture were used.
So, total mixture left = [tex](\frac{7}{4} - \frac{2}{3})L[/tex]
= [tex]\frac{21 - 8}{12}L[/tex]
= [tex]\frac{13}{12}L[/tex]
∴ we get
Total paint left over = [tex]\frac{13}{12}L[/tex]
