A carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.
There are three different sized screws shown. The screws are marked two and a half inches, two inches, and one and a half inches.
What is the ratio of the total length of the 2-inch screws to the total length of all the screws? Do not reduce.
Answers
Step-by-step explanation:
The length of 1.5-inch screws is ...
36 × 1.5 in = 54 in
The length of 2-inch screws is ...
24 × 2 in = 48 in
The length of 2.5-inch screws is ...
12 × 2.5 = 30 in
The total length of all screws is ...
54 in + 48 in + 30 in = 132 in
Then the ratio of 2-in screw length to total screw length is ...
2-in : total = 48 : 132
The ratio of the total length of the 2-inch screws to the total length of all the screws will be 4 / 11.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.
There are three different-sized screws shown. The screws are marked two and a half inches, two inches, and one and a half inches.
The total length of the 2-inch screws is calculated as,
⇒ 24 × 2
⇒ 48 inches
The total length of all screws is calculated as,
⇒ 36 × 1.5 + 24 × 2 + 12 × 2.5
⇒ 132
Then the ratio is calculated as,
⇒ 48 / 132
⇒ 4 / 11
The ratio of the total length of the 2-inch screws to the total length of all the screws will be 4 / 11.

1/2 ft^3
1/4 ft^3
1/8 ft^3
1/9 ft^3
Answers
Answer:
So the answer should be 1/4.
Step-by-step explanation:
so a cube has all equal sides and volume is equal to s^3 or side*side*side in this case 1/2*1/2*1/2. There are two cubes so you would multiply that by two creating 2*1/2*1/2*1/2

As I read it, it says 1 cm : 100 km. And the distance between those two would be 1160 miles. 1160/100=11.6, and 11.6≈11.6 so yes, I dont know what to say. The question answers the answer.
