Our total is x.
Maysa took half of the cherries, so there is .5x left.
Nabilla took half of the remaining, so that is .5*0.5x, which is .25x
Abdulla took 3.
Your equation is:
.25x-3=5
.25x=8
x=32
So there are 32 cherries

Answer:
The answer is "23, 62, and 139"
Step-by-step explanation:
In point a:
[tex]\to \sigma = \$0.24\\\\ \to E = \$0.10\\\\ 95\% \text{confidence level of the z}: \\\\\to \alpha = 1 - 95\% = 1 - 0.95 = 0.05\\\\\to \frac{\alpha}{2} = \frac{0.05}{2} = 0.025\\\\\to Z_{\frac{\alpha}{2}} = Z_{0.025} = 1.96\\\\[/tex]
Calculating the sample size:
[tex]\to n = (\frac{(Z_{\frac{\alpha}{2}} \times \sigma)}{E})^2[/tex]
[tex]= (\frac{(1.96 \times 0.24 )}{0.10})^2\\\\= 22.13 \approx 23[/tex]
In point b:
[tex]\to \sigma = \$0.24\\\\\to E = \$0.06\\\\\to Z_{\frac{\alpha}{2}} = Z_{0.025} = 1.96\\\\\to n = (\frac{(Z_{\frac{\alpha}{2}} \times \sigma )}{E})^2\\\\[/tex]
[tex]= (\frac{(1.96 \times 0.24 )}{0.06})^2\\\\= 61.47 \approx 62[/tex]
In point c:
[tex]\to \sigma = \$0.24\\\\\to E =\$0.04\\\\\to Z_{\frac{\alpha}{2}} = Z_{0.025} = 1.96\\\\\to n = (\frac{(Z_{\frac{\alpha}{2}} \times \sigma )}{E})^2\\\\[/tex]
[tex]= (\frac{(1.96\times 0.24 )}{0.04})^2 \\\\=138.30 \approx 139[/tex]

[tex]Side\ 3 = 5p^2q + 3r[/tex]
Step-by-step explanation:
Given
[tex]Perimeter = 7p^2q + 13r[/tex]
[tex]Side\ 1 = 14r[/tex]
[tex]Side\ 2 = 2p^2q - 4r[/tex]
Required
Find the length of the third side
Perimeter is calculated as thus:
[tex]Perimeter = Side\ 1 + Side\ 2 + Side\ 3[/tex]
This gives:
[tex]7p^2q + 13r = 14r + 2p^2q - 4r + Side\ 3[/tex]
Collect like terms
[tex]Side\ 3 = 7p^2q - 2p^2q + 13r - 14r + 4r[/tex]

Answer:
$28
Step-by-step explanation:
Hello There!
The first thing we want to do is find how much money we earn for washing 1 car
To do so we divide 5 (amount of cars washed) by the money we made from washing those 5 cars
35/5=7
so every car we wash we make 7 dollars
now we multiply the amount of money we make washing one car by 4
4x7=28
so we would earn $28 for washing 4 cars
