Answer:

<h2>48 kg</h2>

solution,

Ratio of cement:sand:aggregate

=1:3:3

Total of ratios=1+3+3

=7

Total concrete=112 kg

Amount of sand required:

\frac{ratio \: of \: sand}{total \: ratio}  \times amount \: of \: concrete \\  =  \frac{3}{7}  \times 112 \\  = 48 \: kg

Hope this helps...

Good luck on your assignment...

Answer:

1- GIK

2- DG

3- obtuse

4- complement 160° , supplement 70°

Step-by-step explanation:

question 1 : GIK are Collinear point cause they are on the same line

question 2 : DG is the parallel segment to CF cause the segment CD is parallel to the segment FG

question 3 : the angle A is obtuse cause it's 93° the obtuse angle is between 90° and 180°

question 4 : the complement is the add of 2 angle that equal 180°

the supplement is the add of 2 angle that equal 90°

complement 160° + 20° = 180°

supplement 70°+ 20° = 90°

The graph of f(x) = 3 . 2*-3 is shown below. g(x) is a transformation of f(x).
DiKsa [7]

Answer: (c)

Step-by-step explanation:

Given

Function f(x) is 3\times 2^x-3

Also, g(x) is the transformation of f(x)

From the graph, it is clear that g(x) passes through the point (0,5)

Now check the option which satisfies the condition

option (c) seems to obey it

g(x)=3\cdot 2^x+2\\g(0)=3\cdot 2^0+2\\g(0)=3\cdot 1+2\\g(0)=3+2\\g(0)=5

Therefore, option (c) is correct.

leva [86]

Answer:

9:19

Step-by-step explanation:

Total number of students = 28

Number of boys = 19

Number of girls = Total number of students - Number of boys = 28-19 = 9

Therefore, ratio of girls to boys = Number of girls/Number of boys = 9/19 = 9:19
