Answer:
i. the length of the of the crab per year is greater than its number of years (x) by 2
ii. length = x + 2
Step-by-step explanation:
i. Given that the size of the hermit crab's shell depends on its size. And it grows 1 inch in a year, then it can be deduced that;
the length of the of the crab per year is greater than its number of years (x) by 2.
ii. To show how large the crab will grow in x years, the required expression that would describe the relationship between the length and years (x) of the crab is:
length = x + 2
lim x → 0, 1, 2,.., x,....
where x is the number of years
Therefore in x years, the length of the crab would be equal to x + 2.
Answer:
x is 9
Step-by-step explanation:
since they are vertical angles, they are congruent. We make an equation putting each one behind the equal sign (7x+3=10x-24) and we solve.
Answer:
300m meters
Step-by-step explanation:
multiply length value by 1000

Step-by-step explanation:
Work in times to fill 1 pail:-
tap A takes 55/4 seconds
tap B takes 50/3 seconds
Let time to fill one pail be x when filling together, then:
3/50 + 4/55 = 1/x
165x + 200x = 55*50
x = 2750 /(365) = 7.5342 seconds
To fill 16 pails it takes 7.5342* 16
= 120.55 seconds
= 2 minutes 1 second to the nearest second..
Density is mass/volume. The mass is given, 32g. To calculate volume, you need to multiply 4*2*3, which is multiplying length, width, and height.
4*2=8
8*3=24
To calculate density, you divide the mass (32) by the volume (24).
32/24= 1.3333333...
Your answer, depending on the person, would either be 1.33, 1.3, 1.33 with the line about the 2 3s, or 1 1/3. Hope this helps! Also, remember to label it g/cm2.
