On solving the equations, the total cost is 25.86.
The cost of ham is $4.80 a pound.
The cost of cheese is $6.3 for a pound.
Cheese weighing pounds was provided for $14.76.
Let "a" represent the cost of a pound of ham, and "b" represent the cost of a pound of cheese.
Given the available information,
1.3a + 0.8b = 11.28 —— (1)
1.50 +1.2b = 14.76 —— (2)
From the equation now (1).
11.28 -0.8b 1.3 (3)
Now, using equations (2) and (3), we obtain the following: 11.28 0.8 b. 1.3)+1.2 b. 14.76. 12.97 0.92 b+1.2 b. 14.76 0.28 b. 1.79 b. 6.3
The result of adding the value of b to equation (3) is 11.28 0.8. (6.3)
1.3 a = 4.8
The cost of ham is $4.80 a pound.
The cost of cheese is $6.3 for a pound.

we know she poured already 2 qts of a 62% sugar solution, hmmm how much will that be in quarts? well, just (62/100) * 2 = 1.24 quarts.
we also know she wants to mixed say "x" quarts of a 38% sugar solution, how many quarts will that be? well, (38/100) * x = 0.38x.

The perimeter of a rectangle is 30cm, it’s width is 6cm. Find its area
Step-by-step explanation:
the area of a rectangle is
length × width.
so, in our case
30 × 6 = 180 cm²
be careful to use the right unit for the result. an area is measured in square units based on the units of the given lengths. hence cm² as the given lengths are in cm.
Use the given information to write an equation of a circle.
center at (-1,-5) , radius 2
Using the given information, the equation of the circle with radius 2 and center at (-1 , -5) is (x + 1)^2 + (y + 5)^2 = 4.
The general form of the equation of circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the general form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (-1 , -5)
r = 2
(x - -1)^2 + (y - -5)^2 = 2^2

an elevation more than 18000 feet above sea level is considered extremely high altitude. supplementary oxygen is recommended when climbing extremely high altitudes. a mountaineer plane to climb a mountain with an elevation of 6282 meters. is supplementary oxygen recommended for the climb? why?
Based on the elevation that the mountaineer has to climb of 6,282 meters, supplementary oxygen is needed because this distance is above 18,000 feet.
How many feet is the mountaineer climbing?The limit for what is considered extremely high altitude is given in feet so the mountaineer's elevation of 6,282 meters needs to be converted to feet.
1 meter in feet is 3.28084 feet.
6,282 meters in feet is therefore:
= 6,282 x 3.28084
= 20,610.24 feet
This distance is more than the 18,000 feet above sea level which makes it extremely high altitude and so supplementary oxygen is needed.

The quotient of 4 divided by 2 1/3 and also explain the mistake that done by Carl
The value of 4 1/3 is 14/3
And the value of 2 1/3 is 7/3
So then we divide 4 2/3 by 2 1/3 is,
[tex]\frac{14 / 3}{7 / 3}=\frac{14}{3} \frac{3}{7}[/tex]

Step: Solve7a−12b=10for a:
7a−12b=10
7a−12b+12b=10+12b(Add 12b to both sides)
7a=12b+10
