McDonalds sells quarter-pound cheeseburgers for .99 cents last saturday.they sold 310 of these cheeseburgers. how many pounds of

Anvisha [2.4K]

The first thing you should do is calculate how many pounds of cheese a hamburger has
1 hamburger = 1/4 pound of cheese.
Then, you can make a rule of three to know how many pounds of cheese were sold:
1 ---> 1/4
310 ---> x
Clearing x we have:
x = ((310) / (1)) * (1/4) = 77.5
Answer
they sell last saturday 77.5 pounds of cheese

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi

PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

$a^2+b^2=c^2$

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

$10^2+b^2=26^2$

Solve the exponents

$100+b^2=676$

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

$100-100+b^2=676-100$

$b^2=576$

Take the square root of both sides

$\sqrt{b^2}=\sqrt{576}$

b=24

So, the other leg is 24 mm

The slope of a line is . -1/3. and the y-intercept is 10/3

Alex_Xolod [135]

Answer:

B

Step-by-step explanation:

If you convert equation B into standard form then:

x + 3y + 10 = 0

x + 10 = -3y

(-1/3)x - 10/3 = y

now this would actually mean that the y-intercept is -10/3 but its the closest answer out of the 3 to the specified requirements for the function.
