In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
The yards of fabric needed is 45.50 yards.
<h3>How many yards of fabric is needed?</h3>
The first step is to determine the total inches of fabric that would be needed for 63 uniforms. The mathematical operation that would be used to determine this value is multiplication.
Multiplication is the process of determining the product of two or more numbers. The sign used to denote multiplication is ×.
Fabric needed for 63 uniforms = inches needed for one uniform x total number of uniforms
63 x 26 = 1,638 inches
The second step is to convert inches to yards
1 inch = 1/36 yards
1638 / 36 = 45.50 yards
Here is the complete question:
Mrs. Taylor is making new football uniforms for Fridays nights homecoming game. The trim for the sleeves of one uniform requires 26 inches of fabric. Mrs Taylor needs to make 63 uniforms total. How many yards of fabric should she buy?

Hey!
Well a soccer field would be a rectangle and if cut across you will be presented with two right triangles. So since you are presented with right triangles you will need to know at least two sides to determine the third. The formula used for right triangles is...
a² + b² = c²
Now a and b are the "legs" of the triangle meaning the two sides that come together to make a 90° angle. The c in the equation would be the hypotenuse of the triangle, otherwise the longest side or in this case the diagonal part. Now to find that distance you will have to plug in and solve...
100² + 230² = c²
10000 + 52900 = c²
62900 = c²
about 250.8 meters
Hope this Helped!

Answer: B) 4</h3>
This is because the z coordinate is -4. So we move down 4 units on the z axis. The z axis is basically a vertical pole planted in the ground, and the xy plane is the flat floor.
It's a bit tricky to visualize so try to imagine that you're in this 3D space personally.
Or you could imagine that something like z = -4 means you are in basement level 4 of a building (say a parking garage) and something like z = 6 means you're on the 6th floor above the ground.
Answer:
x is equal to or greater than 38.
Step-by-step explanation:
use the equation 300+12x to find the amount of money in total dependent on x, the number of hours she worked.
