Answer:
Step-by-step explanation:
By using the Pythagorean theorem:
b^2+3^2=5^2
b^2+9=25
b=sqrt (25-9)
b=sqrt(16)
b=4
=> 4^2+7^2=c^2
16+49=c^2
65=c^2
=>c=sqrt(65)
c = (approximately) 8
Hey,
So first we are told that they charg a fixed fee of 25:00 right?That means even if you didn’t send any text messages you still have to pay 25:00.
So first we have to subtract that 25:00 form 58.25 right?This means the rest of the bill is for text messages OK?
So he spent 33.25(this is the answer to the subtraction) on the text messages right?
And for every text he sent he was charged 0.35 right? So we have to divide 33.25 by 0.35 right?
And that gets us 95.
Now we can double check the answer by multiplieng 95 by 0.35 and adding 25.
So th answer is 95
Hope this helps !!
Answer:
y=-2x^2+10x-12
Step-by-step explanation:
graph is shown in image below
Answer:
L = 12
W = 20
Step-by-step explanation:
The perimeter of the rectangle is 64.
2L + 2W = 64
The length and width of a rectangle are in a 3:5 ratio.
3 + 5 = 8
64/8 = 8
2L = 8 * 3 = 24
L = 24/2 = 12
2W = 8 * 5 = 40
W = 40/2 = 20
Answer:
5/1
