Isa bought a number of pears and apples and paid $128 for them. If a pear costs $3.00 and an apple costs $4,00, how many apples
rodikova [14]

The numbers of pears and apples bought are 16 and 20 respectively

let

x = number of pears

y = number of apples

He bought 4 more apples than pears. Therefore,

  • y = x + 4

He bought a number of pears and apples and paid $128 for them. Therefore,

  • 3x + 4y = 128
<h3>System of equation:</h3>

y - x = 4

4y + 3x = 128

Therefore,

3y - 3x = 12

4y + 3x = 128

7y = 140

y = 140 / 7

y = 20

Therefore,

20 = x + 4

x = 20 - 4

x = 16

Please help!! Evaluate the piece wise function at x=-4 and x=4.
hodyreva [135]

x = -4, so use the first equation, x^2 = -4^2 = -16

x = 4, use 3rd equation, sqrt(x) = sqrt(4) = 2

A quarter falls off a building that is 144
bagirrra123 [75]

Answer:

3 seconds

Step-by-step explanation:

Initial height = 144 feet

t = Time taken

The equation of the height from the ground is

h(t)=-16t^2+\text{Initial height}

The time taken to reach the ground is needed. Here the ground is taken as reference so h(t)=0

0=-16t^2+144\\\Rightarrow -144=-16t^2\\\Rightarrow t=\sqrt{\dfrac{144}{16}}\\\Rightarrow t=3\ \text{s}

So, time taken by the quarter to reach the ground is 3 seconds.
