Use compatible numbers to estimate the quotient394.6 divided by 9

Mathematics
1 answer:
laiz [17]3 years ago
8 0

Answer:

45

Step-by-step explanation:

As a first rough estimate:  divide 390  by 10, obtaining 39.

Another reasonable approximation could be obtained by dividing 450 by 9 and 360 by 9, obtaining 50 and 40.  Since 390 is roughly halfway between 360 and 450, estimate that the quotient is approx 45 (halfway between 40 and 50).

the area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?
Vsevolod [243]

Answer:

perimeters of the rectangle=p=46.014 metres

Step-by-step explanation:

Given that:

Length (l) = 21 m

Area of rectangle(A) = 42.15 meter-square

Width (w)=?

Required data:

Perimater of Rectangle=p=?

Calculation:

As we know that Area of rectangle=A=l*w

Putting the value we get

42.15 m(square)=(21 m)*w

or w=42.15/21

or w=2.007 m

Now to find perimters of rectangle we know that

p=2(l + w) metres

putting the values

p=2(21+2.007) metres

p=2(23.007) metres

p=46.014 metres

I WILL NAME BRAINLIEST FOR WHOEVER CAN WRITE THE ANSWER! I WILL NOT GIVE IT ANYONE WHO JUST POINTS! What is the area of the figu
PtichkaEL [24]

Answer:

48.5cm^{2}

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with 7*8=56 and subtract the triangle.

Area of missing triangle = \frac{1}{2} *b*h (b is the base and h is the height)

Base = 8-3=5

Height = 7-4=3

Area of missing triangle = \frac{1}{2} *5*3=7.5

Area of the figure: 56-7.5=48.5

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: 8*4=32

Area of square: (7-4)*3=9

Area of triangle: \frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5

Total Area: 32+9+7.5=48.5
