If the volume for 3-D polyhedra A is 300 cm3 and the volume for 3-D polyhedral B is 900 cm3. How many times bigger is the volume of pyramid B than pyramid A? Select one:
a. 3%
b. 30%
c. 300%
d. 3000%

Answers

Answer:

c. 300%

Step-by-step explanation:

In order to solve this problem you just have to divide the bigger polyhedral by the smaller polyhedral:

(900 cm^(3) )/(300cm^(3))

As this is equal to 3, you know that the bigger polyhedral is 3 times bigger than the smaller polyhedral so now you just make a rule of three, if an object that is 100% bigger than other is 1 time bigger, what would be the percentage of an object that is 3 times bigger?

(1)/(100)=(3)/(x)

Once you clear the X the equation would look like this:

x=(3*100)/(1)

x=300

If 5x+6=10, what is the value of 10x+3?

A) 4
B) 9
C) 11
D) 20

Answers

Answer: 11  (Option C)

Step by step explanation:

If 5x+6=10

value of 10x+3 = ?

Step 1 : solve the first equation to find the value of x

5x + 6 = 10

5x = 10 – 6

5x = 4

X = 4/5

Step 2 : Susbitute the value of x in the second equation

10x + 3 = ?

10 ( 4/5) + 3  

= 40 / 5 + 3

= 40 + 15 /5 (Taking L.C.M)

= 55 / 5

= 11

I think that the answer is C.11

Solve for x 7x-3=5x+5=

Answers

The value of x in the expression 7x-3=5x+5 is 4

Given

7x-3=5x+5

Here,

The equation is linear in variable x .

7x-3=5x+5

7x - 5x - 3 = 5

2x-3=5

2x = 5 + 3

2x=8

x = 8/2

x=4

Thus the value of x is 4 .

225 grams of flour are needed to make 9 cakes.Marian wants to make 20 of these cakes.
She has 475 grams of flour.
Does Marian have enough flour to make 20 cakes?

Answers

So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs: (225)/(9) = 25 grams of flour

Moreover, 20 cakes need: 20 × 25 = 500 grams of flour

500 g > 475 g

Marian does not have enough flour to make 20 cakes
