Answer:

115 sq cm

Step-by-step explanation:

the shared side (16 cm) separates these two shapes into two trapezoids

the formula for the area of a trapezoid is:

A = 1/2h(sum of bases)

the bases for the left trapezoid are 7 and 16 because they are parallel

the bases for the right trapezoid are also 7 and 16 because they are parallel

the height for one could be 'x' and for the other could be '20-x-'

Area of 1st trapezoid:

A = 1/2x(23)

   = 23x/2

Area of 2nd trapezoid:

A = 1/2(20-x)·(23)

   = 10-x/2·(23)

   = (230-23x)/2

If you add the areas together you get the following:

23x/2 + (230-23x)/2

= 230/2

= 115

Answer: 230cm²

Step-by-step explanation:

>We can do this by splitting the figure into 2 trapeziums.

>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula: \frac{1}{2} * (a+b) * (total height).

>Thus,

Area = \frac{1}{2} *(7+16)*20=230

STatiana [176]
0.5 x 4 = 2 feet / 2 feet in 4 seconds
15 - 2 = 13
New depth: 13 feet

0.4 x 3 = 1.2 feet / 1.2 feet in 3 seconds
13 - 1.2 = 11.8
New depth: 11.8 feet

Lisa [10]

Based on the sample results of the population the percentage of population that  prefers reading a hard copy i fht e digital copy is 4, the hard copy is 21 and n equas 25 is 84%

Step-by-step explanation:

From the above question  we know that .

<u>Total number of population, n = 25</u>

Number of people who prefer to read a digital copy = 4

Number of people who prefer to read a hard copy = 21

As per the question we need to  find out the percentage  of population who prefer to read hard copy.

So we use the formula

<u>Percent of population preferring hard copy = Hard copy/Total*100</u>

<u></u>

Percent of population that prefers  hard copy = 21/25*100

Percent of population that prefers hard copy = 0.84 × 100 = 84%

<u>So , the percent of population who prefers to read a hard copy are about 84%.</u>

<u></u>

What is the value of x in the equation 6(x − 2) − 4x = 16?   A x=14 x=14 B x=4 x=4 C x=2 x=2 D x=12 x=12
prohojiy [21]

Answer:

A)    x=14

Step-by-step explanation:

hello :

6(x − 2) − 4x = 16

6x-12 -4x =16

2x-12=16

add 12 : 2x=16+12

2x= 28

x=28/2=14
