4. The apples bought by Neetu was of weight 3 ¾ kg and the apples bought by Naren was of weight 2 ½ kg. Who bought more apples and by how much more did it weigh?
Answer:
5/4kg
Step-by-step explanation:
Given data
Weight of apples bought by Neetu= 3 ¾ kg
Weight of apples bought by Naren= 2 ½ kg
From the numbers/weights above, Neetu bought more apples
=3 ¾ kg to simple fraction
= 15/4 kg
=2 ½ kg kg to simple fraction
= 5/2 kg
The difference is
=15/4-5/2
=15-10/4
= 5/4kg
Hence Neetus Apples is 5/4kg morethan Narens Apples

Which linear inequality is represented by the graph?
Step-by-step explanation:
the linear inequality is how to measure value of a line through quality and quantity.
Suppose that you throw a rock into the air from the top of a cliff. The initial
upward velocity is 15 m/sec.
a. How high will the rock be above the cliff after two seconds?
b. Where will it be after four seconds ?
c. When will it again be at the same level you threw it?
d. When will it hit the water, 50 meters below the cliff?
Answer:
a. 10.4m above the cliff
b. 18.4m below the cliff
c. Os or 3.1s
d. 5.1s
a) The rock be 10 m above the cliff after two seconds.
b) The rock be 20 m below the cliff after 4 seconds.
c) After 3 second it again be at the same level you threw it.
d) After 5 second it hit the water, 50 m below the cliff.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Since, The formula for the distance,
s = ut - 1/2 gt²
Where, s is distance of an object.
u is initial velocity.
t is time taken by object.
Now,
a) Given that;
t = 2 seconds , u = 15 m/sec , g = 10 m/s
Since, s = ut - 1/2 gt²
Substitute all values we get;
s = 15 × 2 - 1/2 × 10 × 2²
s = 30 - 20
s = 10 m
Thus, The rock be 10 m above the cliff after two seconds.
b) Given that;
t = 4 second,
Then, s = ut - 1/2 gt²
s = 15 × 4 - 1/2 × 10 × 4²
s = 60 - 80
s = - 20
Hence, The rock be 20 m below the cliff after 4 seconds.
c) Given that;
s = 0 meter
Then, s = ut - 1/2 gt²
Substitute all the values,
0 = 15t - 1/2 × 10 × t²
15t - 5t² = 0
5t² - 15t = 0
5t ( t - 3) = 0
Gives, t = 0 second and t = 3second
So, After 3 second it again be at the same level you threw it.
d) Given that;
s = -50 m
Since, s = ut - 1/2 gt²
Thus, Substitute all the values we get,
- 50 = 15t - 1/2 × 10 × t²
15t - 5t² = -50
5t² - 15t - 50 = 0
5 (t² - 3t - 10) = 0
t² - 3t - 10 = 0
By using quadratic formula;
t = -(-3) ± √(-3)² - 4 × 1 × -10 / 2 × 1
t = 3 ± √9 + 40 / 2
t = 3 ± √49 / 2
t = 3 ± 7 / 2
Gives t = 3 + 7 / 2 = 5 second
and , t = 3 - 7/ 2 = -4/2 = -2 second
Thus, After 5 second it hit the water, 50 m below the cliff.
So,
a) The rock be 10 m above the cliff after two seconds.
b) The rock be 20 m below the cliff after 4 seconds.
c) After 3 second it again be at the same level you threw it.
d) After 5 second it hit the water, 50 m below the cliff.

Answer:
8a^3
Step-by-step explanation:
Given that;
2^x = a, we want an expression for 8^(x + 1)
we have this as;
8^(x + 1) = 8^x * 8^1
8^x = (2^x)(3)
8^x is thus same as 2^3x
So replace 2^x by a
Thus, we have a^3
Multiply this by the 8 we had initially; that will give;
8 * a^3 = 8a^3

A player at a basketball camp set a goal to make 55% if his shots. If he has 120 attempts, how many shots would he need to make in order to reach his goal?
Answer: 66
Step-by-step explanation:
From the question, we are informed that a player at a basketball camp set a goal to make 55% if his shots and that he has 120 attempts.
The number of shots that he would he need to make in order to reach his goal will be 55% of 120. This will be:
= 55% × 120
= 55/100 × 120
= 0.55 × 120
= 66
He would need to make 66 shots
