Alonso should work for 38 hours to earn $554.80.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Alonso earned $204.40 at his job when he worked for 14 hours.
Let Alonso per hour be x,
x = 204.40 / 14
x = 14.6
Now,
Alonso works for hours to earn $554.80,
= total pay/pay of an hour
= $554.80 / 14.6
= 38
Alonso should work for 38 hours to earn $554.80.
Thus, Alonso should work for 38 hours to earn $554.80.

“A map uses the scale 3 of an inch represents 3/4 miles. If the actual distance between two cities is
25 miles, then what is the length on the map?”
Answer:
3 = 3/4
but 3/4= 0.75
3 = 0.75
x = 25
cross multiply
0.75x = 75
divide both sides by 0.75
x = 100
therefore 25miles represent 100inch on a map

Write and solve an equation to find the measure of angle B.
Answer:
∠B = 40°
Step-by-step explanation:
The given angle relations can be expressed in two equations.
__
setupA + B = 90° . . . . . . . . angles are complementary
A×(1 -20%) = B . . . . . B is 20% smaller
__
solutionUsing the second equation to substitute for B in the first equation, we get ...
A + 0.80A = 90° . . . . . . substitute for B
A = 90°/1.8 = 50° . . . . . collect terms, divide by the coefficient of A
B = A(0.80) = 40° . . . . find B from A
The measure of angle B is 40°.
A cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 9, the vertical shift is 11 units down, and the period of the function is 12π7. The graph of the function does not show a phase shift.
What is the equation of the cosine function described?
Drag a value into each box to correctly complete the equation of the function
Answer
f(x) = -9 cos((12(pi) / 7)x) -11
The base equation for a cosine graph is
f(x) = a cos(b(x-c))+d
a = amplitude
b = period
c = phase shift
d = vertical shift
if there's a reflection over the x-axis then there is a negative sign in front of the amplitude
I wrote the equation previously but it got deleted so let me know if you have any problems with this explanation
Before training for the obstacle course, Helena bought a new pair of athletic shoes. She placed the shoes on the floor next to each other and noticed that the right shoe looked just like a reflection of the left shoe. If she had accidentally purchased two left shoes, how would this comparison change?
The comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.
What do you mean by reflection?The reflection of a plane or shape is flipping the original figure with respect to a reference line.
The rule of reflection are given below,
Reflection about x-axis (x,y)-->(x,-y)Reflection about y-axis (x,y)-->(-x,y)Before training for the obstacle course, Helena bought a new pair of athletic shoes.
She placed the shoes on the floor next to each other and noticed that the right shoe looked just like a reflection of the left shoe. This is because, the separating line works as the symmetry line between both the shoes.Now she had accidentally purchased two left shoes. Now, if she puts a left shoe to another left shoe, then it looks like the translated image of the first shoe.
Hence, the comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

What is the value of the expression 5x2 + 2x when x = 5?
Answer:
135
Step-by-step explanation:
Given:
[tex]x = 5[/tex]
To determine a numerical value for the expression, simply substitute the value of "x" into the expression and simplify the expression, if necessary, to determine a specific number for the expression provided.
[tex]\implies 5x^{2} + 2x[/tex][tex]\implies 5(5)^{2} + 2(5) \longrightarrow \longrightarrow \longrightarrow (x = 5)[/tex][tex]\implies 5(5)(5) + 2(5)[/tex][tex]\implies 125 + 10[/tex][tex]\implies 135[/tex]Therefore, the value of the expression [tex]5x^{2} + 2x[/tex] when x = 5 is 135.

a laptop that was originally priced at $650 was placed on sale for 25% off. when it did not sell it was put on clearance for 30% off the sale price. what was the clearance price of the laptop
Answer:
$48.75
Step-by-step explanation:
To find 25% of 650 you find 50%. To do this you divide 650 by 2 which is 325. you then divide that by 2 again to get $162.50. That is the sale price.
You now need to find 30% of 162.50. To do that you find 10% 3 times because 10x3 is 30. To find 10% you divide 162.50 by 10 to get 16.25.
16.25x3 is $48.75 which is our answer.
Christine, Kareem, and Trey have a total of $133 in their wallets. Kareem has $5 more than Christine. Trey has 4 times
what Kareem has. How much do they have in their wallets?
Answer:
Christine has $18, Kareem has $23, and Trey has $92.
Step-by-step explanation:
This can be solved by using variables to represent the unkown values.
x = Christine's money
x + 5 = Kareem's money.
4(x + 5) = Trey's money.
x + (x + 5) + 4(x + 5) = 133
2x + 5 + 4x + 20 = 133
6x = 108
x = $18
This means that Christine has $18, Kareem has $23, and Trey has $92.

Answer:
2412.7 ft^3
Step-by-step explanation:
If a circle has a diameter 16ft, it's radius is half that, or 8ft. The are of the circle/base of the cylinder is given by the formula [tex]\pi r^2[/tex] where r is the radius. This means the area is 64π ft^2.
To find the volume of a cylinder, you multiply the base area and the height, so the volume would be 64π x 12 which is 2412.74315796. When rounded to the nearest tenth, this is 2412.7.
Since we want to find the volume of a cylinder:
⇒ must know the formula: [tex]V = \pi r^2h[/tex]
r: radiush: heightConsider the information given:
Height: 12 ftDiameter: 16 ft ⇒ Radius: 8 ft (radius is half of the diameter)Let's solve:
