A theater group made appearances in two cities. The hotel charge before tax in the second city was $1000 lower than in the first. The tax in the first city was 3. 5% and the tax in the second city was 7%. The total hotel tax paid for the two cities was $455. How much was the hotel charger in each city before tax?
Answers
By solving a system of equations we will see that the charge on the first city was $5,000, and on the second city, $4,000.
How much was the hotel charge in each city?
Let's define the variables:
C₁ = charge in the first city.C₂ = charge on the second city.We know that:
C₂ = C₁ - $1000
And we also know that the total tax is $455, then we can write:
0.035*C₁ + 0.07*C₂ = $455
(this says that the total tax is $455)
So we have a system of equations:
C₂ = C₁ - $1000
0.035*C₁ + 0.07*C₂ = $455
We can replace the first one into the second to get:
0.035*C₁ + 0.07*(C₁ - $1000) = $455
0.105*C₁ - $70 = $455
C₁ = ($455 + $70)/0.105 = $5,000
And:
C₂ = C₁ - $1000 = $5,000 - $1,000 = $4,000
The charge in the first city is $5,000 and in the second city was $4,000.

The total remaining bank balance in the account of Omar after reducing all the debit and adding the paycheck is $761.25.
What do you mean by debit and credit amount?The money which is paid from an account is called the debit amount and the money which is paid into an account is called the credit amount.
To know the remaining balance of the account, all the debit amount is subtracted from it and all the credit amount is added to it.
The data given in the table is,
Pharmacy - $15.20-Debited
Rent - $425.00-Debited
Dinner - $22.30-Debited
Movie Ticket - $26.70-Debited
Pay Check - $1015.50-Credited
Initial Balance- $219.80
The initial balance is $219.80, and a paycheck of $1015.50 is credited to his account. Thus, the total balance in his account without any debit is,
[tex]\rm A_i=1015.50+219.80\\\\A_i=1253.30[/tex]
The total amount debited from their account of Omar is,
[tex]\rm A_d=15.20+425+22.30+26.70\\\\A_d=474.05[/tex]
Thus, the total remaining amount in his account is,
[tex]\rm A= 1253.3-474.05\\\\A=761.25[/tex]
Hence, the total remaining bank balance in the account of Omar after reducing all the debit and adding the paycheck is $761.25.

Use 3.14 as an approximation for IT
Answers
Answer:
radius r = 12 m
height h = 5 m
slant height s = 13 m
volume V = 753.982237 m ³
lateral surface area L = 490.088454 m²
base surface area B = 452.389342 m²
total surface area A = 942.477796 m²
The total surface area of cone is 942 cm².
What is Total surface area of Cone?Total surface area is the sum of the area of the circular base and the area of the curved part of the cone.
The total surface area of a cone is the sum of the area of the base and the lateral area:
SA = πr² + πrl
where, r is radius
l is slant height
Now, for finding the slant height of the given cone is
l² = r² + h²
l² = 12² + 5²
l² = 144 + 25
l² = 169
l = 13 cm
Now, SA = π X 12² + π X 12 X 13
= 144π + 156π
= 300π
= 300 X 3.14
= 942 cm²

. Which is a true statement about the transformation?
Answers
Answer: The orientation of the vertices was changed.
(x, y) ---> (x + 8, y - 3)
Step-by-step explanation: The triangle translation isn't on quadrant II, it's on quadrant I, so that answer choice isn't correct. The triangle ABC translated 8 units right and 3 units down, not 8 units left and 3 units up. Whenever you dilate, translate, rotate, or reflect triangles like ABC, the next triangle becomes A'B'C because it shows you that it's a transformation of the original triangle. The orientation of the figure didn't change, because it didn't change shape, rotation, or size, so the orientation wasn't affected at all, just the vertices.
The transformation is (x, y) ---> (x + 8, y - 3), because think of it like this. I already said that the triangle translated 8 units to the right, which means that the triangle is translating 8 units in the positive direction to the right. The triangle going 3 units down is in the negative direction, and that's why it's (x, y) ---> (x + 8, y -3).

Geometric sequence formula: [tex]a_n=ar^{n-1}[/tex]
Given:
[tex]a_{23}=ar^{22}=16[/tex][tex]a_{28}=ar^{27}=24[/tex]Find common ratio (r):
[tex]\begin{aligned}\implies \dfrac{a_{28}}{a_{23}} =\dfrac{ar^{27}}{ar^{22}} & =\dfrac{24}{16}\\ \implies r^5 & =\dfrac32\\ \implies r & = \sqrt[5]{\frac32} \end{aligned}[/tex]
Find initial term (a):
[tex]\implies ar^{22}=16[/tex]
[tex]\implies a(\sqrt[5]{\frac32} )^{22}=16[/tex]
[tex]\implies a(\frac32} )^{\frac{22}{5}}=16[/tex]

You have two sides that are 15m x 6m
(15*6)*2 = 180

Step-by-step explanation:
well, I see one large rectangle (20×6), and 2 small triangles with their horizontal sides being (20-8-6)/2 = 3 m. and their vertical joined side being 10-6 = 4 m.
the total area is simply the sum of the rectangle and the 2 triangles.
the rectangle is
20×6 = 120 m²
each triangle is
4×3/2 = 2×3 = 6 m²
we have 2 of them, so their combined area is 2×6 = 12 m².
the total area is

Here, the lines intersect at the point (0, 9) in the format of (x, y) so we can pull out the answers x = 0 and y = 9.
Answer:
(0, 9)
Step-by-step explanation:
First we need to find the equations of each line!What I'd do is use the equation:gradient (m) = change in y ÷ change in xStarting with the left line, let's pick two coordinates that are on the lineI've picked: (-2, 5), (-3, 3)gradient (m) = (3 - 5) ÷ (-3 - -2) = -2 ÷ -1 = 2We can then use the equation y = mx + c (m is gradient)y = 2x + cWe know we have the point (-3, 3) on this line(-3, 3) = (x, y) so x = -3 and y = 3y = 2x + c3 = 2 × -3 + c3 = -6 + cc = 9Finally, we can say y = 2x + 9Doing the exact same steps for the other line...
y = -3x + 9Since we now have two y = ... equationsWe can say y = yWhich is the same as2x + 9 = -3x + 9We rearrange to find x...5x = 0x = 0That gives us the x-coordinate of where the lines meet (the solution of the system of equations)We can then pick either equation to find the y-coordinate:y = -3x + 9y = -3 × 0 + 9 = 9So the solution we have is at the point (0, 9)!Daniel owns a synall business selling used books.
