Find the surface area.

denpristay [2]

Step-by-step explanation:

a rectangular prism (like this brick) has the same basic structure as a cube (like a die) : it has 6 sides.

while a die has 6 equal sides, a rectangular prism has 3 pairs of equal sides :

top and bottom

left and right

front and back

all we have to do is calculate the areas of the 6 rectangles and add them up. that's it.

your remember, the area of a rectangle is

length × width

in our case we have

top and bottom : 2.5×11.5 × 2 = 28.75×2 = 57.5 in²

left and right : 2.5×5 × 2 = 12.5×2 = 25 in²

front and back : 11.5×5 × 2 = 57.5×2 = 115 in²

so, the total surface area of the whole block is

57.5 + 25 + 115 = 197.5 in²

A recipe for apple pie calls for 1.2 kilograms of apples. If the average apple has a mass of 200 grams, how many apples should b

lutik1710 [3]

Answer:

6Apples

Step-by-step explanation:

Number of apples required for the recipe = 1.2kilograms

But we know that 1000g = 1kg

So;

1.2 kg will give:

1.2 x 1000 = 1200kg

Average mass of the apple = 200g

So;

The number of apples used = $\frac{1200}{200}$ = 6Apples

Match the inequality with its line graph.

Flura [38]

Answer:

Here, answer is given in form of 4 figure labelled with inequality

Step-by-step explanation:

Given inequality are

A). $2x>(-6)$

B). $6+x\leq 3$

C). $x-4$

D). $-x-5\leq (-2)$

For matching with givens graph:

Simplifying...

A). $2x>(-6)$

Divide 2 on both sides

$x>(-3)$

B). $6+x\leq 3$

Add (-6) on both side.

$6+x+(-6)\leq 3+(-6)$

$x\leq(-3)$

C). $x-4$

Add (4) on both side.

$x-4+4$

$x$

D). $-x-5\leq (-2)$

Multiple (-1) on both side

$+x+5\geq (+2)$

Note : Change of inequality sign due to multipication of negative number

Add (-5) on both side.

$x\geq (-3)$

Here, Answer is given in form of 4 figure labelled with inequality
