Answer: 4166.67$
Step-by-step explanation:
1920 x 250 = amount
Amount = 120%
Cost price = 100%
1920 x 250= 120%
Cost price = 100%
Cross multiply and divide both side by 120
1920 x 250 x 100/120 = price
Exchange rate = cost in #/cost in $
= (1920 x 250 x 5/6)/(5000)
= (96 x 5/6) = 16 x 5= 80
Exchange rate then was 80 to 1$
The sales will be 400000/96 = 4166.67$
Answer:
1. $1:#80
2.$5000
Step-by-step explanation:
ok... lots of moving parts here ....
$5000 / 250 = $20 per lantern.
~~~~~~~~~~~~~~~~~~
x (1 + .2) = 1920
x = 1600
~~~~~~~~~~~~~~
$5000 : (1600*250)
$5,000:#400,000
c
~~~~~~~~~~~
sales back to the us at $1:#96
1920*250 = 480000
#480000/#96=$5000

Name the polygon with seven sides_____
a polygon with seven sides is called a heptagon
Answer:
Hyptagon
Step-by-step explanation:
In geometry, a heptagon is a seven-sided polygon or 7-gon.
The heptagon is sometimes referred to as the septagon, using "sept-" (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix "-agon" meaning angle.

15. 70° because a right angle is 90° and we have the angle of ADB which is 20°. So 90°-20°=70°.
16. 70° because angle PSQ is 60° and angle QSR is 10°. So 60°+10°=70°.
17. 55° because it says it in the explanation. I assume this is a typo and they meant to ask the measurement of ADC and in that case it would be 130° because angle ADB is 75° and angle BDC is 55°. 75°+55°=130°.
18. 40° because angle PSQ is a right angle which means it's 90°. So 130°-90°=40°.
19. 140° because angle ADB is 120° and angle BDC is 20° so 120°+20°=140°.
20. 125° because again it's in the explanation. But if it's a typo and they meant what is the measurement of PSQ then it is 50° because PSR is 125° and QSR is 75° so 125°-75°=50°.
Hope this helps! :)

Find the zeros of each quadratic function using any method.
f(x)=(2x+1)(x-3)
===================================================
Explanation:
Set each factor equal to zero and solve for x. This is using the zero product property.
(2x+1)(x-3) = 0
2x+1 = 0 or x-3 = 0
2x = -1 or x = 3
x = -1/2 or x = 3
If you graphed the function, you should see that it crosses the x axis at -1/2 and at 3.

f(x) = 4x2 – 10x + 2
Find f(-7)
Answer:
f(-7) = 268
Step-by-step explanation:
f(x) = 4x^2 – 10x + 2
Let x = -7
f(-7) = 4(-7)^2 – 10(-7) + 2
Exponents first
f(-7) = 4(49) – 10(-7) + 2
Multiply
f(-7) = 196 + 70 + 2
f(-7) = 268
Which number is the EXPONENT? 4^2 = 16 *
Answer: 4
Step-by-step explanation:
The exponent in the given number [tex]4^{2}=16[/tex] is 2.
What is exponent?
An exponent refers to the number of times a number is multiplied by itself.
For example, [tex]3^{4}[/tex] means we are multiplying 3 four times. Here the base is 3 and exponent is 4.
According to the question
We have a number
[tex]4^{2} =16[/tex]
Here, we are multiplying 4 two times. So, the base is 4 and the exponent is 2.
Hence, the exponent in the given number [tex]4^{2}=16[/tex] is 2.

how many ways can Aileen choose 2 pizza toppings from a menu of 19 toppings if each topping can only be chosen one
Answer:
There are 342 different combinations.
Step-by-step explanation:
Ok, Aileen is choosing toppings for a pizza.
She can choose two.
There are 19 options that can be chosen once.
The first thing we need to do, is find all the "selections".
Here we have two selections:
Topping number 1
Topping number 2.
Now we need to find the number of options for each one of these selections:
Topping number 1: Here we have 19 options.
Topping number 2: Here we have 18 options (because one was already taken in the previous selection)
The total number of combinations is equal to the product between the numbers of options.
C = 19*18 = 342
There are 342 different combinations.

The value of the two numbers 'x' and 'y' will be 18 and 27., respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The sum of the two numbers is 45. One number is 9 more than the other one.
Let the two numbers be 'x' and 'y'. Then the equations are given as,
y = x + 9 ...1
x + y = 45 ...2
From equations 1 and 2, then we have
x + x + 9 = 45
2x = 36
x = 18
The value of the variable 'y' is given as,
y = 18 + 9
y = 27
The value of the two numbers 'x' and 'y' will be 18 and 27., respectively.

What is the point of intersection to the system below?
2x - 3y = 5
3x +3y = 5
Answer:
Solution: {x = 2, y = -1/3}
Step-by-step explanation:
On observation, we see that the y-terms are equal and opposite in sign, therefore to solve the system, we add the two equations.
2x-3y = 5 ..........(1)
3x+3y = 5............(2)
(1) + (2)
2x - 3y + 3x + 3y = 5+5
5x = 10
x = 2 .......(3)
Substitute (3) in (2) and solve for x
3x+3y = 5 .....(2)
3(2) + 3y = 5
3y = 5-6 = -1
y = -1/3 .......(4)
assemble (3) and (4) to give the answer
Solution: {x = 2, y = -1/3}

Given:
The quadratic equation is:
[tex]-5x^2-3x-2=0[/tex]
To find:
The discriminant of the given equation and the number of real solutions.
Solution:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the value of discriminant is:
[tex]D=b^2-4ac[/tex]
If D<0, then the quadratic equation has no real roots or two imaginary roots.
If D=0, then the quadratic equation has two equal real roots.
If D>0, then the quadratic equation has two distinct real roots.
We have,
[tex]-5x^2-3x-2=0[/tex]
Here, [tex]a=-5,b=-3,c=-2[/tex]. So, the discriminant of the given equation is:
[tex]D=(-3)^2-4(-5)(-2)[/tex]
[tex]D=9-40[/tex]
[tex]D=-31[/tex]
Since D<0, therefore the number of real solutions is 0.
Hence, the value of the discriminant is -31 and the number of real solutions is 0.
The length of the missing sides
Answer:
length-14cm width-7cm
Step-by-step explanation:
To work out the sides, you can use 2l+2w=42. Since the length is twice the width, this becomes 2(2w)+2w=42.
This can be expanded to 4w+2w=42 or 6w=42.
From there, we can divide both sides by 6 to isolate w, meaning w=7.
Since the length is twice the width, it is given by l=2×7 or l=14.

Step-by-step explanation:
This question is a tricky one, but easy to solve at the same time. Normally the answer to this question would be 1 person = 24 (blank).

Answer:
Ben = $ 41

Step-by-step explanation:
Let initially Ben has $ p and then Kaden has $ (p - 10).
After that
Ben has= $ (p + 4)
Kaden has = $ (p- 10 + 4) = $ ( p - 6)
According to the question,
[tex]p- 6 = \frac{7}{9}\times (p+4)\\\\9 p- 54 = 7 p + 28 \\\\2 p = 82\\\\p =41[/tex]
Initially Ben has $ 41 and Kaden has $ 31.
