Amount spent for food = $5850, housing = $4680, clothing = $2340, savings = $2600, taxes = $5850, expenses = $2080.
Step-by-step explanation:
Step 1:
Given details are Total Income = $23,400
Step 2:
Amount spent for food, F= 1/4th of 23,400 = [tex]1/4 \times 23400[/tex]
= $5850
Step 3:
Amount spent for housing, H = 1/5th of 23,400 = [tex]1/5 \times23400[/tex]
= $4680
Step 4:
Amount spent for clothing, C = 1/10th of 23,400 = [tex]1/10 \times 23400[/tex] = $2340
Step 5:
Amount spent for savings, S = 1/9th of 13,400 = [tex]1/9\times 23400[/tex] = $2600
Step 6:
Amount spent for taxes, T = 1/4th of 23,400 = [tex]1/4 \times 23400[/tex] =$5850
Step 7:
Find amount spent on other expenses by totaling all expenditures and subtracting from the annual income.
Annual Income = F + H + C + S + T + E
Amount spent on other expenses, E = 23400 - (5850 + 4680 + 2340 + 2600 + 5850)
E = 23400 - 21320
E = $2080

Brain May, guitarist for Queen, does not know how to price his signature Antique Cherry Special that cost £280 to make. He know he wants 85% markup on cost. What price should Brian May ask for the guitar?
Answer:
£518
Step-by-step explanation:
Asking price = original cost × markup%
A = 280(1.85) = 518
Brian May needs to price his Antique Cherry Special guitar at £518. This price is determined by the original cost, £280, and a 85% markup, £238, on this cost.
Explanation:Brian May needs to define a price for his signature Antique Cherry Special guitar that was costed at £280 and he wants an 85% markup on this cost. Markup is calculated by multiplying the cost by the markup percentage. In this case, the markup is £280 * 85/100 = £238. Therefore, to determine the final price Brian needs to add the original cost and the markup, which is £280 + £238 = £518. So the price Brian should ask for the guitar is £518.

Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborhood. What is the total number of fliers they gave out
Answer:
The total number of fliers they gave out is 1368.
Step-by-step explanation:
Given:
Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborhood.
Now, to find the total number of fliers they gave out.
Let the total number of fliers be [tex]x.[/tex]
Number of fliers they gave out for a political campaign:
[tex]\frac{21}{38}\ of\ x[/tex]
[tex]=\frac{21}{38} \times x[/tex]
[tex]=\frac{21x}{38}[/tex]
Number of fliers remaining they gave out in another neighborhood = 612.
Now, to get the total number of fliers by putting an equation:
[tex]x-\frac{21x}{38} =612[/tex]
[tex]\frac{38x-21x}{38} =612[/tex]
[tex]\frac{17x}{38} =612[/tex]
Multiplying both sides by 38 we get:
[tex]17x=23256[/tex]
Dividing both sides by 17 we get:
[tex]x=1368.[/tex]
Therefore, the total number of fliers they gave out is 1368.
When a number is decreased by 79%, the result is 13. What is the original number to the nearest tenth?
If a number is decreased by 79%, we are left with 21%.
so let's devide by 21 to get down to 1%, then multiply by 100 to get to the origininal number:
13 / 21 * 100 = 61.9047619048
To the nearest tenth it's 61.9
Final answer:
To find the original number when decreased by 79% to result in 13, we solve the equation 0.21x = 13, which gives us 61.9047619. Rounding this to the nearest tenth gives us 61.9.
Explanation:
To find the original number, we need to translate the percentage decrease back into the original number. Here's the step-by-step calculation:
We understand that after decreasing the original number by 79%, we have 21% of it left, which is equivalent to the number 13.So to find the original number (let's call it x), we set up the equation 0.21x = 13.Divide both sides by 0.21 to solve for x: x = 13 / 0.21 which equals 61.9047619.Round to the nearest tenth. We look at the hundredth's digit, which is 0, we round down the tenth's place to get the final answer, 61.9.So the original number to the nearest tenth is 61.9.

∵ All bases are equal
∴ Use the first and third rule above to find x
∵ [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{3+-6}[/tex]
∴ [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{-3}[/tex] ⇒ L.H.S
∵ [tex]4^{5}[/tex] × [tex]4^{x}[/tex] = [tex]4^{5+x}[/tex] ⇒ R.H.S
Equate L.H.S and R.H.S
∴ [tex]4^{-3}[/tex] = [tex]4^{5+x}[/tex]
Equate the indices of the two sides
∴ -3 = 5 + x

Four to the power of three times four to the power of negative six is equal to four to the power of five times four to the power of negative eight.
To solve for the missing exponent, we can use the following properties of exponents:
Multiplying exponents with the same base: When multiplying powers with the same base, we add their exponents.
Negative exponents: A number raised to a negative exponent is equal to its reciprocal raised to the positive exponent.
Applying these properties:
4^3 * 4^-6 = 4^(3 - 6) = 4^-3 (since 4^-6 = 1/4^6)
4^5 * 4^x = 4^(5 + x)
Setting these equal to find x:
4^-3 = 4^(5 + x)
Therefore, x = -3 - 5 = -8.

how can you determine if a polygon is a convex?
Answer:
You can determine if a polygon is a convex, by which way the edges points out
Convex is when all the points are facing out, so a polygon is a convex if all the edges are pointing out.
Answer:
No side of the polygon crosses any other, even when extended indefinitely.
Step-by-step explanation:
If no sides of the polygon cross each other, it is convex when it has no internal reflex angles (angles measuring more than 180°). If sides of the polygon cross each other, it is not convex.
Another way to describe a convex polygon is that extending any one side indefinitely will not cause it to cross any other side.
The distance between Quebec City and New York City is 520 miles if Kate leaves Quebec and will leaves New York at 9:09 a.m. And they tried toward each other at 55 miles per hour and 75 miles per hour respectively at what time will they meet?
Kate and Will meet at 1 : 09 pm
Solution:
The distance between Quebec City and New York City is 520 miles.
At the point where Kate and Will meet, they would have traveled 520 miles.
Let "t" represent the time it takes Kate to travel a certain distance before they met.
[tex]Distance = speed \times time[/tex]
If Kate drives at 55 mph, the distance covered would be
[tex]Distance = 55 \times t = 55t[/tex]
If Will drives at 75 miles per hour, then the distance covered will be
[tex]Distance = 75 \times t = 75t[/tex]
Since the total distance covered is 520 miles
Which means,
[tex]55t + 75t = 520\\\\130t = 520\\\\t = \frac{520}{130}\\\\t = 4[/tex]
Given that in question,
If Kate leaves Quebec and will leaves New York at 9:09 a.m
4 hours after 9: 09 am, Kate and Will will meet
9: 09 am + 4 hours = 1: 09 pm
Thus they would meet at 1 : 09 pm

E=IZ
Where E=(5+9i) and I=(8+7i)
How do I solve for Z?
Answer:
[tex]Z = \frac{37i }{113 } - \frac{23}{113} [/tex]
Step-by-step explanation:
We have the complex number relationship as:
E=IZ
Where E=(5+9i) and I=(8+7i)
We solve for Z to get;
Z=E/L
We then substitute the expressions to get:
[tex]Z = \frac{5 + 9i}{8 + 7i} [/tex]
We rationalize to get:
[tex]Z = \frac{5 + 9i}{8 + 7i} \times \frac{8 - 7i}{8 - 7i} [/tex]
We simplify to obtain:
[tex]Z = \frac{40 - 35i + 72i - 63}{ {8}^{2} + {7}^{2} } [/tex]
This gives
[tex]Z = \frac{37i - 23}{113 } [/tex]
Or
[tex]Z = \frac{37i }{113 } - \frac{23}{113} [/tex]

Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyramid and is covered in shiny gold foil how much gold foil did it take to cover the chair free including the bottom
Answer:
Akira needs 45 square inches of gold foil to cover the chair free including the bottom
Step-by-step explanation:
Total surface = surface area of the base square + area of 4 triangles
Step 1: The surface area of the base square
surface area of the base = surface area of the square = [tex]s^2[/tex]
where s is the side length
The the surface area of the base = [tex]3^2[/tex] = 9 square inches
Step 2: The surface area of the side triangles
The area of the triangle = [tex]\frac{1}{2}\times \text{side length} \times \text{slant height}[/tex]
On substituting the values,
The area of the triangle =[tex]\frac{1}{2} \times 3 \times 6[/tex]
The area of the triangle = [tex]\frac{18}{2}[/tex]
The area of the triangle = 9 square inches
Now the area of 4 triangles = 4 x 9 = 36 square inches
Thus the total surface area = 9 + 36 = 45 square inches
The amount of gold foil needed to cover a trophy in the shape of a square pyramid can be calculated using the surface area formula for square pyramids, which considers the base area and the slant height.
Explanation:To calculate the amount of gold foil needed to cover the trophy, we need to find the surface area of the square pyramid trophy. The surface area of a square pyramid is calculated by the formula: Surface Area = base area + 1/2 * Perimeter of base * slant height. If we know the length of the base (which is a square here), the slant height, we can substitute them into this formula to get the surface area. This is the amount of gold foil Akira used to cover her trophy, assuming the gold foil perfectly fits the trophy shape with no overlap.

The surface area of a cell phone screen is 6800 mm2. Use the fact that 10 mm = 1 cm to convert this area to cm2. Round your answer to the nearest whole number. Do not type the units in the space below.
Answer:
[tex]68 \: {cm}^{2} [/tex]
Step-by-step explanation:
You can use 1 cm = 10 mm very well to help you with this.
The small two at the end of the unit (cm^2) refers, that the shape of an object is two dimensional. If we make 1 cm two dimensional by multiplying it with the original 1 cm, we get a total area of
[tex]1 \: {cm} \times 1 \: {cm} \: = 1 \: {cm}^{2} [/tex]
We have created an equation. Since we know 1 cm = 10 mm, we can replace the centimetres in the equation with the millimetres, like so:
[tex]10 \: mm \times 10 \: mm = 1 \: {cm}^{2} \\ 100 \: {mm}^{2} = 1 \: {cm}^{2} [/tex]
From there, its just a simple matter of calculation:
[tex]6800 \: {mm}^{2} \times \frac{1 \: {cm}^{2} }{100 \: {mm}^{2} } = 68 \: \: {cm}^{2} [/tex]
