Domarina is making bracelets. she needs 62 cm of gold wire for each bracelet. A roll of wire has 3.10 meters. How many bracelets can she make from one roll of wire.

Answers

Answer:

5

Step-by-step explanation:

To figure this out you first need to find how many centimeters 3.10 meters is worth. 3.10m=310cm. Then, since each bracelet needs 62 cm, you just do 310/62. 310/62=5 So you can make 5 bracelets with one roll of wire.

The area of a rectangle is greater than or equal to 154 square centimeters. The width of the rectangle is 12 centimeters and the length is x centimeters. Select the possible value(s) of x.


x=12

x=12.5

x=13

x=13.5

Answers

Answer: 13 & 13.5

Step-by-step explanation: Since the answer to this can be more than one number, I'll just list off each of these answers and find the possible value.

12x [tex]\geq[/tex] 154

12x12=144

144 < 154 (this doesn't work!)

12x12.5=150

150 < 154 (this doesn't work either!)

12x13=156

156 > 154 (this works!)

12x13.5=162

162 > 154 (this works as well!)

Answer:

13.5

Step-by-step explanation:

The answer is 13.5 because it is greater than 154 and even though 13 is still higher than 154, 13.5 is the highest when multiplied by 12.

Answers

Answer: A

Step-by-step explanation: I think its A because < means less than. So y is less than z. I hope that helps.

the answer is A

the answer is A because the strict inequality sign is “the alligator”. the alligator whats the bigger amount so it’s “eating” letter Z because Z is the greater amount. therefore letter A being the answer.

Answer:

Diameter = 7, Radius = 3.5

Radius = 9, Diameter = 18

Diameter = 12, Radius = 6

Radius = 2.5, Diameter = 5

Step-by-step explanation:

The diameter is the largest line that can be drawn in a circle. It passes from one end of the circle to another, and it goes through the center of the circle. The radius is a line drawn from the center of the circle to the circumference of a circle. By its definition, the radius will always be half of the diameter. Use this information to find the radius of the circle when given the diameter,

Diameter = 7, Radius = 3.5

Radius = 9, Diameter = 18

Diameter = 12, Radius = 6

Radius = 2.5, Diameter = 5

Diameter = 7 Radius = 3.5
Radius = 9 Diameter = 18
Diameter = 12 radius = 6
Radius = 2.5 Diameter = 5
