A plain travels 3400 miles in 8 hours. How far will it travel in 6 hours at this rate
pashok25 [27]

Answer:

2550 miles in 6 hours

Step-by-step explanation:

if you divide the miles and hours by each other you will get the m/ph (miles per hour)

3400 ÷ 8 = 425

now, that we know the plane travels 435 m/ph, then if we multiply it by 6 we will get the answer

425 × 6 = 2550

Tim buys a torch and battery the torch costs 11 times as much as the battery Tim pays with a ?10 note and he gets ?4.84 change h
KengaRu [80]

The cost of 1 battery is 0.43

Step-by-step explanation:

Let the cost of 1 battery be x

We are given that the torch costs 11 times as much as the battery

Cost of torch = 11x

Total cost of 1 battery and torch = 11x+x=12x

Tim pays $10

He receives change of $4.84

Total cost of 1 torch and battery = 10 - 4.84 =$5.16

So,12x= 5.16

x= \frac{5.16}{12}

x=0.43

Hence the cost of 1 battery is 0.43

Please help!!!!! geometry
m_a_m_a [10]

Answer:

58

Step-by-step explanation:

First, draw out your triangle on a piece of paper, and label each point w, x, and y

We are then told that side wx and yw are similar. This means that we have an isosceles triangle with two similar sides.

We are also told that angle w is equal to 64 degrees

with this information, we can assume that angle y is the same as angle x

Another important thing to note is that all triangle measures equals to 180

SO

we can make this expression:

64 + x + x = 180

Now to solve for x:

64 + x + x = 180

64 + 2x = 180

2x = 116

x = 58
