Answer:
y≥-3x+4
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
You follow bedmas (brackets, exponents,division,multiplication,addition,subtraction). First comes the brackets so you do (60 divided by 10) which is 6. You still have (6) which means you have to multiply it by 2. So you get 12. Now you got rid of the brackets so you can solve the rest. 90-12-4= 74.
Volume is a three-dimensional scalar quantity. The volume of the right-triangular pyramid is 1.008 m³.
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of a right-triangle pyramid is one-third of the product of its base area and its height. Therefore, the volume is,
Volume = (1/3) × 0.5 × 1.4 × 1.8 × 2.4
= 1.008 m³
Hence, the volume of the right-triangular pyramid is 1.008 m³.

Answer:
1. 8t
2. 510 + 6t
3. 510 - 2t
Step-by-step explanation:
1. Since the hare moves at a speed of 8 metres per second, the distance it moves from the starting line is d = speed × time = 8t
2. Since the rabbit moves at a speed of 6 metres per second, and gets a head start of 510 metres, the distance it moves from the starting line is d = 510 m + speed × time = 510 + 6t
3. The distance the tortoise is ahead of the hare is thus, distance moved by rabbit - distance moved by hare in time, t.
d' = 510 + 6t - 8t
= 510 - 2t
