Answer:
10 teeth must go on the driven gear
Step-by-step explanation:
Let the number of teeth be x
In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that
17:5 = 34:x
∴ 10 teeth must go on the driven gear
hence ratio = 34:10
51.25 per month which is $615 per year
They save 5 per month if they pay full year
(51.25-5)= 46.25 per month is $555
so it costs $555 if they pay all at once.
Answer:
224 cubes
Step-by-step explanation:
1. Find the area: 2 * 1 *7/4 = <em>7/2 cm³</em>
2. Find how many cubes fit into 1 cm³: 4 * 4 * 4 = <em>64 cubes</em>.
3. Multiply the two numbers: 7/2 * 64 = 224 cubes.
X/7-4=-2 u add two to both sides
x/7-2=0you add two to both sides again
x=14 u multiplied 7 and 2 and by x
