If the parallelogram floor needs a base of 16 feet,what will the height of the floor be

nydimaria [60]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete because the area of the parallelogram is missing. However, the following will guide you in answering the question</em>

Given

$Base = 16\ ft$

Required

Determine the Height

Area of a Parallelogram is:

$Area = Base * Height$

Make Height the subject

$Height = \frac{Area}{Base}$

Substitute 16 for Base

$Height = \frac{Area}{16}$

This implies that you divide the value of area by 16 to get the height of the parallelogram.

Take for instance;

$Area = 64ft\²$

The height would be

$Height = \frac{64}{16}$

$Height = 4\ ft$

$Area = 80ft\²$

The height would be

$Height = \frac{80}{16}$

$Height = 5\ ft$

F) Two numbers are in the ratio 5:4. If they differ by 12, what are the numbers?

Iteru [2.4K]

Answer:

First number = 60 and another number = 48

Step-by-step explanation:

Let two numbers are 5x and 4x.

The two number are differ by 12. We need to find the numbers.

ATQ,

5x-4x = 12

x = 12

Now first number = 5x

= 5(12)

= 60

Other number = 4x

= 4(12)

= 48

Hence, the numbers are 60 and 48.

Two customers went to a post office to buy postcards and large envelopes. Each postcard

astraxan [27]

The right answer is Option A.

Step-by-step explanation:

Let,

x be the postcards

y be the large envelops

According to given statement;

14x+5y=12 Eqn 1

10x+15y=24.80 Eqn 2

Multiplying Eqn 1 by 3;

$3(14x+5y=12)\\42x+15y=36\ \ \ Eqn \ 3$

Subtracting Eqn 2 from Eqn 3;

$(42x+15y)-(10x+15y)=36-24.80\\42x+15y-10x-15y=11.20\\32x=11.20\\$

Dividing both sides by 32

$\frac{32x}{32}=\frac{11.20}{32}\\x=0.35$

Putting x=0.35 in Eqn 1;

$14(0.35)+5y=12\\4.90+5y=12\\5y=12-4.90\\5y=7.10$

Dividing both sides by 5

$\frac{5y}{5}=\frac{7.10}{5}\\y=1.42$

Therefore, one large envelope costs $1.42

The right answer is Option A.
