Mathematics

Answer:

Lateral Surface Area: 56 in²

Total Surface Area: 81 in²

Step-by-step explanation:

To find the lateral surface area, all we need to do is find the surface area for one of the lateral faces and then multiply it by 4.

\frac{1}{2} *b*h

\frac{1}{2} *5*5.6=2.5*5.6=14

Now the area of all the lateral faces:

14*4=56

The total surface area is the lateral area plus the base.

56+(5*5)=56+25=81

Last year , there were 30 male members and 20 female members in a Chess Club . This year , the number of male members is decreas
LekaFEV [45]

The r% of a quantity x is computed by dividing x in 100 parts, and considering r of such parts. So, the r% of the male is

30\times\cfrac{r}{100} = 0.3 r

and similarly, the r% of female is

20\times\cfrac{r}{100} = 0.2 r

The number of males decreased by this quantity, so now it is

30 - 0.3r

and the number of female increased by this quantity, so now it is

20+0.2r

we know that these two new counts are the same number, so we can build and solve the equality

30 - 0.3r = 20+0.2r

Subtract 20 and add 0.3r from both sides:

10 = 0.5r

Divide both sides by 0.5 to solve for r:

r = 20

Let's check the answer

The 20% of 30 is 30 \times \frac{20}{100} = 6, while the 20% of 20 is 4. So, we are stating that 30-6 = 20+4 which is true because both expressions evaluate to 24.

What is 162% of 400? Rounded to the nearest hundredth.
finlep [7]

Answer:

648

Step-by-step explanation:

Write 162% as  162 /100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

162 /100  of 400 =  162 /100 × 400

Therefore, the answer is 648

If you are using a calculator, simply enter 162÷100×400 which will give you 648 as the answer
