How can you find a unit rate when given a rate?

1 answer:

7 0

It depends on the problem really. One example is that you drive 10 miles in 2 hours. So you divide the distance over time to get 10/2 = 5. This means you drove 5 miles per hour (mph). The unit rate for this example is 5 mph.

On Monday, Nalim made a journey.

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.

Answer:

1 ruler costs $0.60

Step-by-step explanation:

$20-$4.70=$15.30

Calculator =$7.50

3 Packs of Pens = $1.80 each

4 rulers= x each

$7.50 + 3($1.80) + 4x = $15.30

7.50 + 5.40 + 4x = 15.30

12.90 + 4x = 15.30

4x = 2.40

x = 0.60

I needdd helppppppp plsss

Answer:

Step-by-step explanation:

3 - 6 = -3
Plug -3 in: $-\frac{12}{-3} + (-1)^{3}$
Simplify the fraction. Two negatives equal a positive. It should now look like this: $\frac{12}{3} + (-1)^{3}$
Simplify even more. Divide 12 by 3, and change -1 to a positive by removing the plug sign: $4 - 1^{3}$
$1^{3} = 1$
Plug 1 in: 4 - 1
4 - 1 = 3

I hope this helps!
