laurens suv was detected exceeding the posted speed limit of 60 kilometers per hour , how many kilometers would she have been tr
Vlada [557]

Answer:

60 kilometers per hour (kmph) over the limit

Step-by-step explanation:

The speed limit is 60 kmph

Let's find his original rate:

We know D = RT

Where

D is the distance, in km

R is the rate, in kmph

T is the time in hours

He went 10 km in 5 minutes, so we need the time in hours, first. That would be:

5/60 = 1/12 hour

So, putting into formula, we find rate:

D = RT

10 = R(1/12)

R = 10/(1/12)

R = 10 * 12

R = 120 kmph

He was going over by:

120 - 60 = 60 kmph

Find the values of a and b such that x2 - 2x + 2 = (x -a) + b LOADS OF POINTS ON THE LINE!!!
Hitman42 [59]

Answer:

Step-by-step explanation:

Factorize using square root method.

x² - 2x + 2 = (x-a)² + b

x² -2x + 1 + 1 = (x-a)²+b

(x² - 2*x*1 + 1²) + 1 = (x -a)²+ b       {Compare with a²- 2ab+b² which is (a - b)²}

(x - 1)² + 1 = (x - a)² + b

a = 1 and b = 1

A farmer sells 8.3 kg of apples and pears at the farmers market this way is apples and Restless Paris how many kilograms of Pari
Serga [27]

Answer:

She sell <u>2.075 kilograms</u> of pears at the farmer's market.

Step-by-step explanation:

<u><em>There is a mistake in the question some data is missing, so the correct question is below: </em></u>

<em>A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?</em>

Now, to find the kilograms of pears.

Total weight of apples and pears = 8.3 kg.

Weight of apples = \frac{3}{4} of 8.3 kg.

So, to get the weight of apples:

  \frac{3}{4} \times 8.3

=0.75\times 8.3

=6.225\ kg.

Thus, the weight of apples = 6.225 kg.

Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:

8.3-6.225\\\\=2.075\ kg.

Therefore, she sell 2.075 kilograms of pears at the farmer's market.
