Answer:
its A & B, x<50
Step-by-step explanation:
atmost means till 50.
atleast means more than 50.
Well this type of problems isn't exactly my strong suit, but I tried to come up with a solution, so my reasoning is as follows: we know that 1km is 0.621 miles, and the problem incites us to find how much time 1 mile takes, so we need to find how many kms are in a mile:
1km ---> 0.621 miles
<=> 1/0.621=1.610 km ---> 0.621/0.621 = 1 mile
so 1 mile = 1.610 km
Next we need to know how much time 1.610 km takes to run across
We know that:
10 km take 55 mins
and 1.610 = 10/6.211
so we need to divide 55 by the same value
55/6.211 = 8.855 mins
So 10 km ---> 55 mins
1.610 = 10/6.211 km ---> 55/6.211 = 8.855 mins
I hope I didn't mess up.
Hope I helped ^^
The monthly loan payment should be $168.75.
<h3>Calculation of the monthly loan payment;</h3>
Since Ally is buying a speed boat for $10,000 with a down payment of $2,500. The bank approved a simple interest flat rate loan for 5 years at 7% APR.
The net principal should be
= $10,000 - $2,500
= $7,500
Now simple interest should be
= $7,500(5)(7%)
= $2,625
Now the total amount should be
= $7,500 + $2,625
= $10,125
Now the monthly payment is

= $168.75
Therefore, The monthly loan payment should be $168.75.

Answer:
a. 754cm³ (3 s.f.)
b. 415cm² (3 s.f.)
Step-by-step explanation:
Formulas (for easier reference):
Volume of cone:
r²
Volume of hemisphere: 
r³
Surface area of cone without base:
rl
Surface area of hemisphere without base: 2
r²
We can just apply the formulas for the question:
Volume of toy = (
× 6² ×
) + (
×
6³)
= 96
+ 144
= 240
= 754cm³ (3 s.f.)
Surface area of toy = (
× 6 × 10) + (2 ×
× 6²)
= 60
+ 72
= 132
= 415cm² (3 s.f.)
