The cost c of these t-shirts in her currency of Krona is; C: 608.313 Krona
How to carry out conversion of currency?
We are told that;
A foreign exchange student wants to buy gifts for her family.
She gets a deal at;
7 shirts = $97.93
Now, she wants to buy 5 shirts for her family at that given deal. Thus;
Cost of 5 shirts in dollars = (97.93 * 5)/7 = $69.95
Now, the exchange rate of dollar to krona is given as;
1 U.S. Dollar = 8.6964 Krona
Thus; $69.95 = (69.95 * 8.6964)/1 = 608.313 Krona

Hector left his house at (-7,11) on a map of coleville and walked to the zoo at (-7,3) from there he walked east to his friends house. He walked a total distance of 25... if each unit on the map represents one block, what are the coordinates of Hectors friends house?
The coordinates of Hector's friend's house are (18,3).
What is the Coordinate System?A Cartesian coordinate system or coordinate system can be used to locate any point, and that point can then be shown as an ordered pair (x, y) known as coordinates. The origin, symbolized by the letter "O," is the point where the two number lines cross. The X-axis and Y-axis of a number line are the horizontal and vertical axes, respectively.Given:
Coordinates of Hector's house = (-7,11)
Coordinates of zoo = (-7,3)
He walked a total distance of 25 blocks from the zoo towards the east.
This means that he walked horizontally on the y-axis to reach his friend's house. So, the y-coordinate remains 3 and only the x-coordinate varies.
To find the coordinates of Hector's friend's house,
As given each unit on the map represents one block.
25 units = 25 blocks
Adding 25 units to the x- coordinate of the zoo keeping the y-coordinate same to obtain the required coordinates.
- 7 + 25 = 18
Therefore, the coordinates of Hector's friend's house are (18,3).

The points (0,k) and (1,4) fall on a line with a slope of 9. What is the value of k?
Answer:
k = - 5
Step-by-step explanation:
calculate the slope between the 2 points using the slope formula and equate to 9
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, k ) and (x₂, y₂ ) = (1, 4 )
m = [tex]\frac{4-k}{1-0}[/tex] = [tex]\frac{4-k}{1}[/tex] = 4 - k
then equating to 9
4 - k = 9 ( subtract 4 from both sides )
- k = 5 ( multiply both sides by - 1 )
k = - 5

A jeweler wants to make a silver alloy to be used to make necklaces. How many ounces of a silver alloy that costs $5.50 per ounce should be mixed with one that costs $8.00 per ounce to make a new 20-ounce alloy that costs $7.00 per ounce?
$5.50 grade oz
$8.00 grade oz
Thank you :)
Answer and Explanation:
Let x be the total weight of the silver alloy costing $3.50 per ounce and y be the the total weight of the other that costs $7.00 per ounce.
The total weight of the resulting alloy is 30 ounces.
x+y=30x+y=30
Each ounce of the mixture must cost $6.30. The total cost of the resulting silver alloy is:

8 ounces of silver alloy that costs $5.50 per ounce should be mixed with 12 ounces of silver alloy that costs $8.00 per ounce to make a new 20-ounce alloy that costs $7.00 per ounce.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the number of ounces of silver alloy which costs $5.50 per ounce and y be the number of ounces of silver alloy that costs $8.00 per ounce.
We have,
x + y = 20
5.50x + 8.00y = 7 × 20
From the first equation, x = 20 - y
Substituting this in the second equation,
5.5 (20 - y) + 8y = 140
(5.5 × 20) - 5.5y + 8y = 140
110 + 2.5y = 140
2.5y = 30
y = 12
x = 20 - y = 20 - 12 = 8
Hence the number of $5.50 cost per ounce silver alloy used is 8 ounces and the other alloy used is 12 ounces.

The percentage profit on the cost of the skirt is 11.1%
Here, the cost of gloves is £4
And the profit on gloves is 100% which will be equal to 4
The selling price of gloves will be = 8
As given in the question,
The total selling price of both items is £48
So, the selling price of a skirt will be = 48-8
= 40
Now, let the Total Cost of both items be x
Then, x*120÷5= 48
On solving the equation we get the x= 40
So, the cost price of the skirt will be = 40 - 4 = 36
Profit percentage of the skirt =( Selling price - cost price÷ cost price)*100
= (40-36÷ 36)*100
=(4÷ 36)*100

If you just want to conduct a flyby and aren't planning to stay, it will take you approximately 600 days, and if you want to enter orbit, it will take you about 2,000 days.
WHAT IS LIGHT YEAR ?Astronomical distances are expressed in terms of a light-year, which is also spelt light year. Its length is approximately 9.46 trillion kilometers, or 5.88 trillion miles.
HOW LONG IT WOULD TAKE TO REACH JUPITER FROM EARTH ?NASA's Pioneer 10 was the first spacecraft to ever travel across the distance between the Earth and Jupiter. On March 3, 1972, it was launched, and on December 3, 1973, it arrived. There were 640 days of flight time altogether.
However, Pioneer 10 was passing by while en route to study the outer solar system. Before NASA lost communication with it, the spacecraft traveled another 11 years into deep space after approaching the planet at a distance of 130,000 kilometers, where it snapped the first-ever close-up images of Jupiter.

Tickets to a Broadway show cost $40 for adults and $10 for children. The total receipts for 1420 tickets at one performance were $41,800. How many adult and how many child tickets were sold?
The number of adult tickets sold is 920 , and the number of child tickets sold is 500 .
In the question ,
it is given that
ticket cost for adult = $40
ticket cost for children = $10
and the number of total tickets sold is 1420
let the number of adult tickets sold = x
and the number of children ticket sold = y
According to the question
total tickets sold = number of adult tickets sold+ number of children ticket sold
Substituting the values, we get
x+y = 1420
y = 1420 - x ...(i)
the total receipts for adult tickets= $40x
the total receipts for children tickets= $10y
given that total amount of tickets sold = $41800
According to the question
40x + 10y = 41800
Substituting the value of y from equation(i) , we get
40x + 10(1420-x) = 41800
40x + 14200 - 10x = 41800
30x + 14200 = 41800
30x = 27600
x = 920
and y = 1420 - 920
y = 500
Therefore , the number of adult tickets sold is 920, and the number of child tickets sold is 500 .
