sergejj [24]
The answer is:  [D]:  11  1/2  .
___________________________________________________________

Explanation:
___________________________________________________________
 2  7/8 <span>÷ 1/4  =

23/8  </span>÷  1/4 =  23/8 * 4/1 ;  The "4" cancels to a "1"; and the "8"
                                                       cancels to a "2";  (since "8÷4 =2" ;
                                                                                and "4÷4 = 1" ;
__________________________________________________________
  → 23/8 * 4/1 =  23/2  * 1/1   = 23/2  * 1  =  23/2 = 11  1/2 ; 
__________________________________________________________
                                                      → which is:  Answer choice:  [D].

Jug A has 0.1 litres more than jug B. Jug C has 200 millilitres less than jug B. Jug D has ¼ of the amount that is in jug A. The
Gnesinka [82]

Answer:

A = 0.8 litres

B = 0.7 litres

C = 0.5 litres

D = 0.2 litres

Step-by-step explanation

Here's what we know:

1. Jug A = B + .1 litres

2. Jug C = B - 200 (or 0.2 litres)

3. Jug D = .25 x A

4. Jug A + Jug B = 1.5 litres

In problem 1, we learned that Jug A has .1 litres more than Jug B and in problem 4, the two of them added together are 1.5 litres. To solve this we can combine the problems.  

B + .1 litres + B = 1.5 litres

2B + .1 = 1.5

Subtract .01 from each side and you have 2B = 1.4

Divide each side by 2 and you have B = 0.7 litres

Plug this info into problem 1 and you can solve for A. (0.7 + 0.1 = 0.8)

Plug this info into problem 2 and you can solve for C. (0.7 - 0.2 = 0.5)

Since you have A, you can use that info to solve problem 3 (0.25 x 0.8 = 0.2)

A line segment has endpoints Q(-16, -12) and R(21, -8).
gulaghasi [49]

Answer:

(2.5, - 10 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2} , \frac{y_{1}+y_{2}  }{2} )

here (x₁, y₁ ) = (- 16, - 12 ) and (x₂, y₂ ) = (21, - 8 ) , then

midpoint = ( \frac{-16+21}{2} , \frac{-12-8}{2} ) = ( \frac{5}{2}, \frac{-20}{2} ) = (2.5, - 10 )
