Start with 
b/4.9=-20.6 

Multiply both sides by 4.9 you will be left with b

b=-20.6*4.9
b=-100.94

-100.94/4.9=-20.6

How many cubic blocks of side length
Andrei [34K]

Answer:

To find how many blocks it would take in each of these scenarios, you could find the total volume and then divide by the volume of each smaller cube.

1.  3/7 x 3/7 x 3/7 = 27/343 cubic inches

    1/7 x 1/7 x 1/7 = 1/343 cubic inches

27/343 cubic inches  divided by 1/343 cubic inches = 27 cubes.

2.  3/7 x 1/7 x 3/7 = 9/343 cubic inches

9/343 cubic inches divided into groups of 1/343 cubic inches is 9 cubes.

3.  2/6 x 2/6 x 2/6 = 8/216 cubic inches

8/216 cubic inches divided by 1/216 cubic inches is 8 cubes.

Another way to think of it would be for #1, each 3/7 of an inch would be 3 groups of 1/7, so 3 x 3 x 3 for each dimension would result in 27 cubes.

For #2, it would be 3 groups of 1/7, one group of 1/7 and another 3 groups of 1/7, so 3 x 3 is 9 cubes.

For #3 it would be 2 groups of 1/6 three times, so 2 x 2 x 2 = 8 cubes.

Whats the area of the lawn in this shape
Licemer1 [7]

Answer:

208 ft

Step-by-step explanation:

in order to do this we need to find the area of the retangle:

(l x w) 14x20= 280ft

then the area of the rectangle:

a^2 + b^2 = c^2 ( hypotenus lenght )

c= 8.5

now we can plug in to find the area of the triangle, which is 12 (11.99)

then the area of the trapezium= 60

finally we can find the answer

280 - (60+12)= 208 ft :)

At an archeological site, the remains of two ancient step pyramids are congruent. If ABCD= EFGH find EF
Pani-rosa [81]

Answer:

EF = 44 ft

Step-by-step explanation:

Given that ABCD is congruent to EFGH, it follows that their corresponding lengths and angles would be congruent to each other.

This means, for the sides:

AB = EF,

BC = FG,

CD = GH

AD = EH.

Therefore, if AB = 44 ft, corresponding side, EF = 44 ft

What does initial value mean?<br><br> (The topic matter is linear functions)
vagabundo [1.1K]
Initial value can mean many things, but what I believe it means in this area is the value that you start with (obviously), so in the equation (y=mx+b), the initial value is the b. It is where the line intercepts the y-axis, and that is your initial value, I believe!
I hope this was helpful and answered your inquiry! If you have any further doubts or questions, please let me know so that I can help you!
