Mathematics

xenn [34]3 years ago

Answer:

Step-by-step explanation:

Let's put in some numbers to make this easier to understand.

Let's say she has to travel 20 km.

On Monday, she travels at 4 kph.  This takes 5 hours.

On Tuesday she travels 25% faster, at 5 kph.  This takes 4 hours.  

To figure percent reduction we take

100 % * (old - new) / old  

100 % * (5 hr - 4 hr ) / 5 hr

100 % * 1 hr / 5 hr

100 % * 0.20

20% reduction.

What is the slope of the line that passes through the points (2 3) and (–2 6)?
frutty [35]
Answer: Choice B) -3/4

------------------------------------------

Work Shown

Slope Formula
m = (y2-y1)/(x2-x1)
m = (6-3)/(-2-2)
m = (3)/(-4)
m = -3/4

Basically what you do is subtract the y coordinates (6 and 3) and then do the same for the x coordinates (-2 and 2) in the same order. After subtracting, you divide the differences. Reduce the fraction if possible. 

The slope of -3/4 means each time we go down 3, we move to the right 4 units. This line is going downhill as you read it from left to right.

the length of the quilt - 1⅓X

X•(1⅓X)=4800
1⅓X²=4800
X²=3600
X=60

the width of the quilt - 60 inches

At the beginning of the week, James stopped by a local grocery store to buy fruit. He bought five bananas and three pears at a t
suter [353]
Lets try to solve this problem using 2 equations, also,we will have bananas=b and pears =p

5b+3p= $3.80
2b+4p= $3.20  i will divide this equation by 2 and get
b+2p= $ 1.60  we subtract 2p from both side so i can find the cost for 1 banana
b+2p-2p=1.60-2p
b= $1.60-2p

I will replace the b in the first equation now,

5(1.60-2p)+3p=$3.80
8-10p+3p=3.80   solving for p
8-7p=3.80     we subtract 8 from both sides
-7p=-8+3.80
-7p=-4.20  we multiply both sides by (-1)
7p=4.20  we divide now both sides by 7
p=0.60   a pear cost 0.60 cents

a banana is b=1.60-2p,   b=0.40 cents
