Answer:
x-1.77=13.73
x=15.50
Step-by-step explanation:
First, we susbitute variable x for the amount earned. Next as she spent 1.77 and has 13.73 remaining we derive x-1.77=13.73. Finally, add 1.77 to both sides to get x=15.5.
Answer:
The equation is x - 1.77 = 13.73.
The simplified version is x = 15.50.
Step-by-step explanation:
The equation is x - 1.77 = 13.73.
The simplified version is x = 15.50.
To get to this answer, we first need to plug the provided numbers into a simple equation.
We can assume that "x" (the unknown number) is the total. The total minus the amount of money spent, $1.77, will equal the new total, $13.73.
Therefore, x - 1.77 = 13.73.
Next, we need to solve the problem. By adding 1.77 to both sides of the equal sign, we effectively isolate the variable.
-1.77 + 1.77 = 0; 13.73 + 1.77 = 15.50.
We can, at last, come to the conclusion that x = 15.50.

A waterfall has a height of 1900 feet. A pebble is thrown upward from the top of the falls with an initial velocity of 12 feet per second. The height, h, of the pebble after t seconds is given by the equation h=-16t^2+12t+1900. How long after the pebble is thrown will it hit the ground?
Answer:
Step-by-step explanation:
h is the height of the pebble after a certain amount of time has gone by. Since we are told to find that time when the pebble is on the ground, we say that h = 0 since the height of something on the ground has no height at all. Then factor the quadratic.
[tex]-16t^2+12t+1900=0[/tex]
Throw that into the quadratic formula or however you were taught to factor irrational quadratics (maybe completing the square?) to get that
t = 11.27869 sec and t = -10.52869 sec
Since we all know that time will never carry a negative value, we will disregard it and go with 11.27869 seconds. Not sure to where you are told to round.

Answer:
C. 100πk⁸
Step-by-step explanation:
Given that the surface area of a sphere = 4π(5k⁴)²
Let's simply
Take the square of what you have in the bracket, that's the square of the radius, 5k⁴.
4π(5²k⁴*²)
= 4π(25k⁸)
= 4*25*π*k⁸
= 100πk⁸

The $347 selling price for a stereo is $35 more than 3 times the wholesale cost. Write
and solve an equation to find the wholesale cost.
Hello!
[tex]\large\boxed{\$104}[/tex]
We can write an expression to display this scenario:
$347 is $35 more than 3 times the wholesale cost (x), so:
3x + 35 = 347
Subtract 35 from both sides to isolate x:
3x + 35 - 35 = 347 - 35
3x = 312
Divide both sides by 3:
3x/3 = 312/3
x = $104
What should I choose
Answer:
5x+18y
Step-by-step explanation:
3x+2x=5x
11y+7y=18y
Combine Like terms
3x + 2x = 5x
11y - 7y = 4y (I'm asumming that the blanks are subtracting signs)
Therefore, 5x + 4y

What is the cross-sectional area of a cement pipe 2 in. thick with an inner diameter of 5 ft? Use pie 3.14.
Answer:
1.60 [tex]ft^{2}[/tex]
Step-by-step explanation:
Assuming that this is a cylindrical pipe, the area can be determined by applying the formula for calculating the area of a circle.
i.e Area = [tex]\pi[/tex][tex]r^{2}[/tex]
So that,
for the inner part of the pipe,
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 2.5 feet
Area of the inner part of the pipe = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x [tex](2.5)^{2}[/tex]
= 19.625
Are of the inner part of the pipe is 19.63 [tex]ft^{2}[/tex].
Total diameter of the pipe = 5 + 0.2
= 5.2 feet
r = [tex]\frac{5.2}{2}[/tex]
= 2.6 feet
Area of the pipe = [tex]\pi[/tex][tex]r^{2}[/tex]
= 3.14 x [tex](2.6)^{2}[/tex]
= 21.2264
Area of the pipe is 21.23 [tex]ft^{2}[/tex].
Thus the cross sectional area = Area of the pipe - Area of the inner part of the pipe
= 21.2264 - 19.625
= 1.6014
The cross sectional area of the cement pipe is 1.60 [tex]ft^{2}[/tex].

a shoe store uses a 60% markup for all the shoes it sells what would be the selling price of a pair of shoes as a wholesale cost of $51
Answer:
81.60 is your selling price
Step-by-step explanation:
60% = 0.60
0.60 x 51 = 30.60
51 + 30.60 = 81.60
The selling price of shoes after a markup of 60% of the price will be equal to $81.60.
What is the Percentage?The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.
As per the given information in the question,
The wholesale price of shoes = $51
There is a markup of 60% on every shoe.
Then the price of shoes will be,
$51 + $51 × (60/100)
$51 + 30.6
= $81.60

Round to the greatest place to estimate 23 x 1.75
IM GIVING AWAY 11 POINTS
Answer:
I think the answer is 992.5
After rounding off to the greatest place, the expression will be equivalent to 46.
What is rounding of in numbers?
Rounding numbers means adjusting the digits of a number such that it gives an estimated result. If the digit next to the digit which is to be rounded is less than 5, round down and if the digit is 5 or more than 5, than round up.
Given is to round off 23 x 1.75 to the greatest place.
We have the following expression -
23 x 1.75
We will no round of 23 as it would become 20, which is less than 23 itself. However, we will round off 1.75. Since, 75 > 49, we can round
1.75 to 2.00. Now, the expression becomes - 23 x 2.00. On multiplying, we get - 46
Therefore, after rounding off to the greatest place, the expression will be equivalent to 46.

Answer:
Angle 1 is 140.
Step-by-step explanation:
Set angle 1 and angle 3 equal to each other since they are congruent to each other to get this equation 20x+60=30x+20. Subtract 20x on both sides to get this equation 60 = 10x + 20. Subtract 20 on both sides to get to 40 = 10x. Divide 10 on both sides to get your x-variable which is 4. Since you are solving for angle 1, plug in the x-value to get 20(4)+60. You should get 140 degrees as your final answer.
Sabrina plans to apply for a loan that requires a down payment at the end of this year what will help her reduce the total cost of the loan
Answer:
D. reducing the loan term and increasing the down payment
Step-by-step explanation:
Sabrina's loan balance should be lowered in order to have a lower interest. Therefore, she should "increase her down payment." An increase in down payment means a smaller loan balance.
In addition to this, she should also reduce the loan term because extending the term will most likely lead to an increase overall interest. Although the monthly payment is smaller than a shorter loan term, the overall amount Sabrina will pay is actually bigger.
