Step-by-step explanation:

3.

the net of a cylinder looks like a rectangle with two circles attached at opposite ends. we also define a base radius for the cylinder as the radius of the base, and the height of the cylinder as the distance between the bases.

in other words, imagine you cut open a soda can (and leave the top and bottom just a little bit attached - don't cut them off completely).

the mantle turns into a rectangle. and the base and top are two circles. the length of the rectangle is the circumference of one of the circles (2×pi×r), and the width of the rectangle is the height of the original can.

4.

remember what you did when calculating the size of the area of a square ? or a rectangle ?

in each case it is in principle length×width.

and we expressed an area not in units of e.g. cm but in cm², because we simply said how many little squares of 1 unit side length fit into the area.

now, for the volume, we apply the same principle and simply add a third dimension.

we express a volume not in cm² squares but in cm³ cubes, saying how many such little cubes fit inside.

a cube with 5 cm side length has therefore a volume of

5×5×5 = 5³ = 125 cm³ (= 125 little cubes of 1cm side length).

5.

this is simply a box, a 3-dimensional rectangle.

similar to 4. fit the volume we just multiply now so 3 dimensions :

6×7×9 = 378 cm³ (= 378 little cubes of 1cm side length).

if the length of a rectangle is increased by 30 percentage and the width of the same rectangle is decreased by 30 what is the af

LUCKY_DIMON [66]

Answer:

The area will decrease by 9%.

Step-by-step explanation:

The area of a rectange is given by the formula below.

$\boxed{\text{Area of rectangle}= \text{length}×\text{width}}$

Let the original length and width of the rectangle be L and W respectively.

Start by finding the original area:

Original dimensions

Length= L= 100%L

Width= W= 100%W

Original area= LW

Let's find the dimensions of the new rectangle in terms of L and W.

New dimensions

Length= (100% +30%)L= 130%L

Width= (100%-30%)W= 70%W

New area

$= \frac{130}{100} L \times \frac{70}{100} W$

$= \frac{91}{100} LW$

= 91% LW

Comparing the new area with the original area:

100% LW- 91% LW= 9% LW

∴ The area will decrease by 9%.

*Note that percentage is equivalent to dividing a number by 100.

What is the value of the algebraic expression if x= 1/2 , y = -1, and z = 2? 6x(y2z) A. -12 B. -6 C. 1 D. 6

Free_Kalibri [48]

To determine the value of the given algebraic expression above, we simply substitute the values of each variable to the variables in the expression and evaluate the expression. We do as follows:

6x(y^2)(z)
when x = 0.5
y = -1
z = 2
6(0.5)((-1)^2)(2)
3(1)(2)
6

The value of the algebraic expression would be 6. An algebraic expression consists of variables which are represented with letters like for this case x, y and z, a coefficient which is indicated by numbers (e.g. 6 ) and exponents like 2 for the expression above. Often times expressions contains a number of terms which consists of those elements.

A trail traveled 90 miles in 1.5 hours. At the same rate how long will it take the train to travel 330 miles

Arisa [49]

4.5 hours is 270 miles so just find out how long 60 miles takes and add that to 4.5 hours.
