Answer:
You have to pay 9.6.
Step-by-step explanation:
In order to find the answer, first you have to consider that 1 pound is equal to 16 ounces and with that information, you can use a rule of three to find the pounds that 24 ounces represent:
1 pound → 16 ounces
x ← 24 ounces
=(24*1)/16=1.5
Now that you know, that 24 ounces are equal to 1.5 pounds you can multiply the price per pound for the number of pounds to find the amount that you need to pay:
6.4*1.5=9.6
According to this, the answer is that you have to pay 9.6.
Answer:
Lateral areas have ratio of 4:1
Volumes have ratio of 8:1
Step-by-step explanation:
There is a rule in 3D geometry that when two solids are similar, and their edges are in the ratio of 
, the ratio of any surface area type measure is always 
this includes the lateral area, which is just a surface area minus the base, which is not important for this problem. The ratio of volumes of those similar solids is in the ratio of 
.
Now, to solve this, we need to find the ratio of any corresponding length of these similar pyramids. We have both the heights, so if we form a ratio of 
which if you simplify it, it is 
, which is 
. The ratio of the heights are 
.
Now we can apply those rules to this ratio, the ratio of lateral areas would then be 
, which is 
. the ratio of volumes would be 
, which is 
Answer:
D=M/V
D=65.1/6.2
Density is 10.5 grams per centimetre cube
Step-by-step explanation:
Change everything into 10ths as follows:
1/10 + 2.5/10 = 3.5/10 of an hour to make one bracelet. Then change to 20ths so the numerator is a whole number.
Divide your time available by the time it takes to make one.

4 = 420= 15 bracelets

(as a whole number there was no fraction or remainder to round off)
Step-by-step explanation:
points (-7,5) and (5,-3)?
This would mean to subtract the y coordinates:
5 - (-3) = 8
Then subtract the x coordinates in the same order:
-7 - 5 = -12
Then divide the y result by the x result for the slope:
8/-12 is the slope.
In simplest form, this is equivalent to -2/3
