Answer:
Step-by-step explanation:
If Quan had 15 and Kaden had 3 times as much, then Kaden had 15(3) = 45. If he spent 10 then he had 35 left. The amount of money Quan had after his mom gave him some was 4/5 the amount of Kaden's 35 (let x = the amount of money Quan has after his mom gives him some):
35 divides by the 5 in the denominator 7 times, and 7 times 4 is 28. That's how you get your 28 in part a.
For part b., he started with 15 and ended with 28, so his mom gave him 28-15=13. That's how you get the 13.
Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.

The amount of metal needed to make the metal stud for the costume is 12 unit²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the meatal stud does not have a base, hence:
Amount of metal needed = sum of area of triangular faces = 4(1/2 * 2 * 3) = 12 unit²
The amount of metal needed to make the metal stud for the costume is 12 unit²

Area of lane=area of rectangle
=180x5=900m²
Area of brick=0.2x0. 15
=0.03m²
No of bricks needed=900/0.03
=30000
Cost of bricks=30000/1000x750
=30x750=22500
