Answer:
340 phones
Step-by-step explanation:
Make an expression
She repairs 10 phones each day, d.
Each day she repairs 10 phones, it is 10 phones off the total number (450) she has to repair, so we can subtract 10d from 450.
450-10d
We want to find how many she has left after 11 days, so we can substitute 11 in for d
450-10(11)
Multiply
450-110
340
She will still have 340 phones left to repair
Answer:
Solve the following system for x and y:
{2 x + 53 = 53, 8 x + 3 = 42}
Check whether x and y are present in the given system:
Answer: The variable y is not present. Therefore its value cannot be determined.
Step-by-step explanation:
<span>127.3 feet
This problem requires the use of pythagoras theorem. Ignore the face that it's a baseball diamond. All you're concerned with is that you have a square that's 90 feet per side and you want to know what the length of the diagonal. So you have a right triangle with 2 sides of 90 feet each and you want to know the length of the hypotenuse.
The formula is
C^2 = A^2 + B^2
Both A and B are 90, so plugging them into the formula gives
C^2 = 90^2 + 90^2 = 8100 + 8100 = 16200
So
C^2 = 16200
Take the square root of both sides
C = 127.2792
Round to the nearest tenth, giving
C = 127.3</span>
