just olya [345]

Answer:

253cm²

Step-by-step explanation:

Area of the trapezoid = 1/2(b1+b2)*h

Given

h = 22cm

b1 = 10.5cm

b2 = 12.5cm

Substitute

Area of the trapezoid = 1/2(10.5+12.5)*22

Area of the trapezoid = 1/2(23)*22

Area of the trapezoid =11*23

Area of the trapezoid = 253cm²

Hence the area of the trapezoid is 253cm²

THIS IS EASY BUT IM DUM SO I DONT GET IT

Question: What is 35 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$40=100\%$40=100%​.

Step 4: Similarly, $x=35\%$x=35%​.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$40=100%(1)​.

$x=35\%(2)$x=35%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{35\%}$
40
x​=
100%
35%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{35}{100}$
x
40​=
35
100​​

$\Rightarrow x=14$⇒x=14​

Therefore, $35\%$35%​ of $40$40​ is $14$ B. 14%
