Answer:

GCF = 8

Step-by-step explanation:

Find the prime factorization of 48

48 = 2×2×2×2×3

Find the prime factorization of 56

56 = 2×2×2×7

To find the GFC, multiply all the prime factors common to both numbers

Therefore, GCF = 2×2×2

GCF = 8

Winnie wrote the following riddle.I am a number between 60 and 100.My ones digit is two less than my tens digit.I am a prime num
Kazeer [188]

Answer:

79

Step-by-step explanation:

60<xy<100

y -2 =x


if it is prime

y cannot be even

so y could be      1,3,5,7,9

x would then be 9,1,3,5,7

but to be between 60 and 100

x must be 7 or 9

so the number must be 79 or 57

57 is not prime so

the number is 79

2 x - 17 = 11.<br> Help please
Svet_ta [14]

Step-by-step explanation:

Perhaps you want to solve the equation for the value of x. If so then let us work it out:

2x - 17 = 11 \\ 2x = 11 + 17 \\ 2x = 28 \\ x =  \frac{28}{2}  \\  \huge \red { \boxed{x = 14}}

Ann [662]

Answer:

268 cm^2

Step-by-step explanation:

Pink prism:

top: 2 cm * 2 cm = 4 cm^2

right, left, back, front: 4 * 2 cm * 6 cm = 48 cm^2

bottom: completely covered in connection to green prism

Total surface area of pink: 52 cm^2

Green prism:

bottom: 10 cm * 5 cm = 50 cm^2

front, back: 2 * 10 cm * 4 cm = 80 cm^2

right, left: 2 * 5 cm * 4 cm = 40 cm^2

top: 10 cm * 5 cm - 2 cm * 2 cm = 46 cm^2

Total surface area of green: 216 cm^2

Total surface area of composite solid:

52 cm^2 + 216 cm^2 = 268 cm^2

A scale model of a tower is 24 inches tall and 18 inches wide. If the height of the actual tower is 60 feet, what is its width?
pochemuha

We can set up a proportion to solve this problem as follows:

height of the model/width of the model= height of the actual/width of the actual

24/18=60/x

Cross multiply,

24x=18*60

24x=1080

x=45 ft.

Therefore the answer is 45 ft.
