60 divided by the ratio of 7:3
wariber [46]
First find the total of the ratio:
7 + 3 = 10

Now we can divide 60 by 10:
60 divided by 10 is 6

Finally we can multiply both 7 and 3 by 6:
7 x 6 = 42
3 x 6 = 18

To check we can add 42 and 18: this gives us 60.

Answer: 42:18

Hope this helps!

I need help please.<br> Given the function h(t)=2t*+9,evaluate h(5)
Yakvenalex [24]
For this case we have the following function:
 h (t) = 2t + 9&#10;
 We want to calculate h (5).
 To do this, we must evaluate the value of t = 5 in the given function.
 We have then:
 h (5) = 2 (5) + 9&#10;&#10;h (5) = 10 + 9&#10;&#10;h (5) = 19
 Answer:
 
The value of h (5) for this case is given by:
 
h (5) = 19

In complete sentences, explain whether or not it makes sense to say the population density of a town is 145 people per block
tatiyna
I'm unsure as to whether or not you have the complete question posted, but I will work with what you gave. 

It is possible to say that the population density of a town is 145 people per block. It can depend on how many people live in each house, if there are any vacant houses, how many houses are on each block, and if there are any apartments on the blocks. Without certain details concerning them, one can only assume, but from the details that I have it is certainly possible to have 145 people living on each block.

3/5 (10x + 15) = +30 help me please
sergeinik [125]

Answer:

x = 3.5

Step-by-step explanation:

\frac{3}{5} (10x + 15) = 30

10x + 15  = 30 * \frac{5}{3}  

10x + 15   = 10 * 5

10x + 15   = 50           {Subtract 15 form both sides}

         10x = 50 -15

        10x = 35         {Divide both sides bt 10}

    10x/10 = 35/10  

          x = 3.5
