Given the dimensions of the brick, we first calculated its volume in cubic meters. Then we calculated the volume of the wall in cubic meters. Dividing the volume of the wall by the volume of a single brick, we find that we need 20,000 bricks to build the wall.
This is a problem in Mathematics, specifically involving volume and unit conversion. The volume of the brick can be calculated using the formula for the volume of a rectangular prism, Volume = length x width x height. The dimensions given for the brick are in centimeters and the wall dimensions are given in meters. Therefore, we must convert the brick dimensions to meters: 30 cm = 0.3 m, 10 cm = 0.1 m and 7.5 cm = 0.075 m. The volume of one brick is 0.3 m * 0.1 m * 0.075 m = 0.00225 cubic meters.
The volume of the wall is also given by the formula length x width x height, so it is 30 m * 2 m * 0.75 m = 45 cubic meters. To find the number of bricks required to fill this volume, divide the volume of the wall by the volume of a single brick, 45 m³ / 0.00225 m³ = 20000 bricks. Thus, it will take 20,000 bricks to build the wall.

all you have to do is multiply 30*2*3/4
to get 45
The rate of change of f is twice the rate of change of g.
B.
The rate of change of g is twice the rate of change of f.
C.
The rate of change of f is 3 times the rate of change of g.
D.
The rate of change of f is the same as the rate of change of g.
Answer:
A. The rate of change of f is twice the rate of change of g.
Step-by-step explanation:
The first function is
The slope of this function is the coefficient of x. It is the same as the rate of change of f(x)
From the graph, g(x) passes through(-2,-4) and (0,2)
We use the slope formula: to find the slope of g(x).
Since 6=2(3), we conclude that, the rate of change of f is twice the rate of change of g.
Answer:
A
Step-by-step explanation:
A pencil with length { 7in or, 8in. or, 9in. or, 10in. or, 11in.}
A cοnversiοn factοr is a number used tο change οne set οf units tο anοther, by multiplying οr dividing.
When a cοnversiοn is necessary, the apprοpriate cοnversiοn factοr tο an equal value must be used.
Fοr example, tο cοnvert inches tο feet, the apprοpriate cοnversiοn value is 12 inches equals 1 fοοt.
Given that,
we have to name one object that is more than 6 inches but less than 1 foot.
now, we know that,
6 inches < 1 foot
as, we have,
1 foot = 12 inches
now, we know that,
more than 6 inches but less than 1 foot means,
anything more than 6 inches but less than 12 inches or 1 foot.
now, we get, the object can be any thing with length of more than 6 in. & less than 12in.
i.e. length is < 12 and, length is > 6
so, the possible lengths are = { 7in, 8in. , 9in. , 10in. , 11in.}
so, we get,
A pencil with length { 7in or, 8in. or, 9in. or, 10in. or, 11in.}
Hence, name one object that is more than 6 inches but less than 1 foot is, A pencil with length { 7in or, 8in. or, 9in. or, 10in. or, 11in.}

6 inches < 1 foot
anything more than 6 inches but less than 12 inches or 1 foot
Answer:
Option B
Option C
Step-by-step explanation:
we need to divide the coefficient of x by half since it is required for completing square, this term is added and subtracted at the same time to keep the equation intact, so we have
later we have
we know
we have
or
so we have
finally
The second is obtained by summing the two given equations
f(x)=8x-10
g(x)=3x+5
-----------------
f(x)+g(x)=11x-5
