Mathematics

7 0

Answer:

21.04

Step-by-step explanation:

Start by adding the hundredths category. 0.09 + 0.05 = 0.14, this means that your hundredths column will be a 4, and you will carry the 1 over to the tenths.

Now add your tenths. 0.0 + 0.9 + 0.1 = 1.0, which means that your tenths column is a 0. Carry the 1 over to the whole numbers.

Now add your whole numbers. 7 + 13 + 1 = 21. Combine your terms and you get 21.04

Aahil, James and merav share £90 in the ratio 1:3:5 how much does merav get

Dafna1 [17]

Given: £90 is divided among Aahil, James and Merav in the ratio 1:3:5.

To find: How much Merav gets.

Answer:

Let's assume the shares of each to be 'x'.

This implies that 1x + 3x + 5x = 90.

9x = 90

x = 90/9

x = 10

Substituting this value of x in the ratio,

1 × 10 = 10 [Aahil's share]
3 × 10 = 30 [James' share]
5 × 10 = 50 [Merav's share]

Therefore, Merav gets £50.

Hope it helps. :)

svp [43]

Answer:

the probability of drawing a pink rose from the bunch of roses is 25%

Step-by-step explanation:

assuming that each rose es equally likely to be chosen then the probability of picking one pink rose is

probability = number of pink roses / total number of roses = 3 / (5+3+2+2) = 3/12 = 0.25 (25%)

then the probability is 25%

Jamie recently drove to visit her parents who live 510 miles away. On her way there her average speed was 25 miles per hour fast

tino4ka555 [31]

Answer:

Average speed in mph with which he goes to parent's place = 75 mph

Average speed with he comes back = 50 mph

Explanation:

Distance between Jamie's house and parent's house = 510 miles.

Let u be the average speed in mph with which he goes to their place.

We have the average speed of coming back = (u -25) mph

Total time of journey considering both ways = 17 hours.

Time taken to go their home = 510/u hours

Time taken for coming back = 510/(u-25) hours

So total time = $\frac{510}{u} +\frac{510}{u-25}$

Equating both times we have

$\frac{510}{u} +\frac{510}{u-25}=17\\ \\ 510u-12750+510u=17u^2-425u\\ \\ 17u^2-1445u+12750=0\\ \\ u^2-85u+750=0\\ \\ (u-75)(u-10)=0$

u = 75 mph or u =10 mph

If the average speed in mph with which he goes to their place = 75 mph, average speed with he comes back = 75-25 = 50 mph

If the average speed in mph with which he goes to their place = 75 mph, average speed with he comes back = 10-25 = -15 mph(Not possible)

So, Average speed in mph with which he goes to parent's place = 75 mph

Average speed with he comes back = 50 mph
