Answer:

922.832

Step-by-step explanation:

We are asked to multiply 27.4 by 33.68.

We can write our given problem as a multiplication problem without decimal as:

3368

X 274

13472

235760

673600

922832

We can see that both numbers has three digits after decimal, so we will plot a decimal three digits from the right as:

$27.4\times 33.68=922.832$

Therefore, our required product is 922.832.

4/9 divided by what equals 12

Dahasolnce [82]

(4/9)/x= 12

Multiply both sides by x
4/9=12x

Divide both sides by 12
(4/9)*(1/12)= 4/108
4/108= 1/27

Final answer: 1/27

Olivia drives 90 miles in 2 hours. She drives 225 miles in 5 hours. She writes an equation in the form y=mx to represent the num

saul85 [17]

Answer:

$y=270\textrm{ miles}$

Step-by-step explanation:

Given:

Number of miles is represented by $y$ and number of hours is represented by $x$ .

The equation to show the relationship between $x$ and $y$ is $y=mx$

Now, for $x=2,y=90$

Plug in the above equation and solve for $m$ . This gives,

$90=m(2)\\m=\frac{90}{2}=45\textrm{ mi/h}$

Hence, the equation is $y=45x$ .

Now, if the line passes through $(6,y)$ , then $x = 6$ .

So, $y=45(6)=270\textrm{ miles}$

Therefore, the value of $y$ is 270 miles.

Two students were given the expression shown to simplify. Use the drop-down menus to complete the statements about whether each

sdas [7]

Answer:

Step-by-step explanation:

6 - (2 - 4x)

sophia : 6 + 2 + 4x

sophia's expression is incorrect because she didn't distribute the negative sign thru the parenthesis correctly.

ursula : 6 - (-2x)

ursula's expression is incorrect because....well....I dont know how she got what she got...she possibly subtracted 2 from - 4x and got -2x

a correct equivalent expression is : 6 - 2 + 4x or 4 + 4x

A cylindrical roller 2.5 m in length, 1.5 m in radius when rolled on a road was found to cover the area of 16500 m2 . How many r

eduard

Answer:

701 revolutions

Step-by-step explanation:

Given: Length= 2.5 m

Radius= 1.5 m

Area covered by roller= 16500 m²

Now, finding the Lateral surface area of cylinder to know area covered by roller in one revolution of cylindrical roller.

Remember; Lateral surface area of an object is the measurement of the area of all sides excluding area of base and its top.

Formula; Lateral surface area of cylinder= $2\pi rh$

Considering, π= 3.14

⇒ lateral surface area of cylinder= $2\times 3.14\times 1.5\times 2.5$

⇒ lateral surface area of cylinder= $23.55 \ m^{2}$

∴ Area covered by cylindrical roller in one revolution is 23.55 m²

Next finding total number of revolution to cover 16500 m² area.

Total number of revolution= $\frac{16500}{23.55} = 700.6369 \approx 701$

Hence, Cyindrical roller make 701 revolution to cover 16500 m² area.

a rectangular piece of paper 71 cm long and 10m wide . a cylinder is formed by rolling the paper along its length , find volume

natka813 [3]

Answer:

Volume=355 cm³

Step-by-step explanation:

I assume it should be 10 cm, not 10 m. If it is 10 m, everything will have to be adjusted.

Circumference = 2 $\pi$ r

10=2 $\pi$ r

10÷2 $\pi$ =r

1.59=r

V= $\pi$ r²h

V= $\pi$ (1.59)(71)

v=355
