X = -1
y = 2
m = -3/4
b = ?

2 = -3/4 (-1) + b
2 = 3/4 + b
1.25 = b

y = -3/4x + 1 1/4

standard form: 3x + 4y = 5

What shows the volume

Svetllana [295]

Answer:

654 1/2 cm³

Step-by-step explanation:

First the volume of the cylinder, the formula for that is πr²h

Radius is half of diameter so 7/2=3.5

3.5^2=12.25

12.25x22/7=38.5

38.5x15=577.5

Now the cone, the formula for this is πr²h/3

It has the same radius as the cylinder so 3.5^2=12.25

12.25x22/7=38.5

38.5x6=231

231/3=77

Now we add them together to find total volume.

577.5+77=654.5

Kira walks 8hole and one half blocks in 17 minutes.if kira continues to walk at the steady pace, how many blocks will she walk e

ZanzabumX [31]

8 1-and-a-half blocks would be 12 blocks, and so 12/17, because 12 blocks in 17 mins., so you divide 12 by 17 to get ---- blocks per minute, which is 12/17 as a fraction, or approx. 0.705882353 blocks per minute.

Mrs. Wheeler had a bowl of M&M’s sitting on her table. Her daughter Lauren told her that she thought there were 100 M&M’

laiz [17]

There was 33.3% error in her calculation.

Step-by-step explanation:

Approx value thought by Lauren = 100

Exact value counted = 75

Percent error = $\frac{|approx-exact|}{exact}*100$

$Percent\ error=\frac{|100-75|}{75}*100\\\\Percent\ error=\frac{|25|}{75}*100\\\\Percent\ error=\frac{2500}{75}\\\\Percent\ error=33.33\%$

Rounding off to nearest tenth;

Percent error = 33.3%

There was 33.3% error in her calculation.
