Answer:
6 boys and 11 girls
Step-by-step explanation:
hello,
let 's note x the number of boys and y the number of girls, we can write two equations
"there are a total of 17 kids"
(1) x + y = 17
"There are 5 more girls than boys"
(2) y = x + 5
We can replace (2) in (1) it comes
x + x + 5 = 17
<=> 2x = 17-5 = 12
<=> x = 6
and then y = 11
So, there are 6 boys and 11 girls

Answer:
121.5 tonnes of earth will be removed
Step-by-step explanation:
The first thing to do here is to calculate the area of this shape.
We can see that we have three different rectangles here
So the area of the shape is the sum of the areas of the rectangles
This will be;
(18 * 1) + (13 * 1) + (23 * 1) = 18 + 13 + 23 = 54 m^2
Wondering how we got 23?
You know the total top length is 25, removing 1n from each side leaving the central value will
give a rectangle of 23 by 1
Now, digging the foundation to a depth of 1.5m
The volume dug will be = area of shape * depth of digging = 54 * 1.5 = 81 m^3
Now, 1 m^3 has mass of 1.5 tones, 81 m^3 will have a mass of 81 * 1.5 = 121.5 tonnes
