This can be expressed by the equation 520 = 1.3x
So, we divide 520 by 1.3 and get 400 :)

So from 100% you increased it by 30% to become 520
130%=540
percent means parts out of 100
130%=130/100=1.3
1.3 of whole=520
divide both sides by 1.3
whole=400

the number was 400

The pizza shop owner tells Mrs. Rodriguez that 3 jumbo Cookies can feed 10 students.
oksano4ka [1.4K]

Answer:

3(60/10)

Step-by-step explanation:

10 students require 3 cookies, which you already know. So, since you need to find for 60, you can divide 60 by 10 into 6. Then, 6x3 will equal 18. Or, you can say:

10=3

20=6

30=9

40=12

50=15

60=18

10x2=3x2 and so forth....

Daniel has 2 3/8 pounds of
crimeas [40]

Answer:

NO IF 14 POUND BURGERS

NO IF 1/4 POUND BURGERS

Step-by-step explanation:

2   3/8 POUNDS < 10

10- 2 3/8 = 7 5/8 REQUIRED TO MAKE 10  1 POUND BURGERS

If 1/4 pound burgers then you can just divide 1/4 into 2 3/8

= 2 3/8 / 1/4 = 9.5 BURGERS   = No

Because 10-9.5 = 0.5 burger required

1/2 burger is not equivalent to 1 whole burger.

Help me please with geometry ​
Yuri [45]

Answer:

Step-by-step explaunfere:

The circumference of a circle is the distance around the outside of the circle. The diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference.

1- C ≈ 50.27 in

2- C ≈ 31.42 in

3- A ≈ 201.06

4- A ≈ 314.16

5- C = 14π = 43.982 ≈ 44 inches

π (Pi) times the Radius squared: A = π r2

or, when you know the Diameter: A = (π/4) × D2

or, when you know the Circumference: A = C2 / 4π
