Two similar solids a and b are shown

Mathematics

Alona [7]4 years ago

Answer:

see explanation

Step-by-step explanation:

Given 2 similar solids with ratio of sides = a : b , then

ratio of areas = a² : b²

ratio of volumes = a³ : b³

Here ratio of sides = 3 : 6 = 1 : 2 , thus

ratio of areas = 1² : 2² = 1 : 4

ratio of volumes = 1³ : 2³ = 1 : 8

(a)

The volume of solid B is 8 times volume of A, that is

volume of solid B = 8 × 60 = 480 cm³

(b)

The area of solid A is one- quarter the area of solid B, that is

surface area of solid A = 140 ÷ 4 = 35 cm²

A box contains 4 plain pencils and 4 pens. A second box contains 3 color pencils and 7 crayons. One item from each box is chosen
Zolol [24]
P ( pen from first box) =  4/8 = 1/2
P(crayon from second box) = 7/10

as these events are independent the individual probabilities are multiplied 
so P( pen and crayon) = 1/2 * 7/10 = 7/20

In a Laboratory, the count of bacteria in a certain experiment was increasing at the rate of 2.5% per hour. Find the bacteria at
DedPeter [7]

Answer:

5,31,616 bacteria

Step-by-step explanation:

Solution:

Here, Principal (P) = 5,06,000, Rate of Interest (R) = 2.5%, Time (n) = 2 hours

After 2 hours, number of bacteria,

Amount (A) = P\left(1+\frac{R}{100}\right)^nP(1+100R)n

= 506000\left(1+\frac{2.5}{100}\right)^2506000(1+1002.5)2

= 506000\left(1+\frac{25}{1000}\right)^2506000(1+100025)2

= 506000\left(1+\frac{1}{40}\right)^2506000(1+401)2

= 506000\left(\frac{41}{40}\right)^2506000(4041)2

= 506000\times\frac{41}{40}\times\frac{41}{40}506000×4041×4041

= 5,31,616.25

Hence, number of bacteria after two hours are 531616 (approx.).

Solve 2x^2 = 72.<br> Question 1 options:<br> {±18}<br> {±36}<br> {±6}<br> {±8}
Marat540 [252]
All you do is have to plug each option in for x
2*18^2=684
2*36^2=2592
2*6^2=72
2*8^2=128
So it's C.6
