Answer:
8.7
Step-by-step explanation:
14² - 11² = x
196-121= 75
√75= 8.66
so rounding it would be 8.7
The dilation is a transformation in which the size of the preimage is
reduced by 0.5.
- The coordinates of the point Q' following the dilation of the point Q(0, 2) is
![\underline{Q' = (0, \, 1)}](https://tex.z-dn.net/?f=%5Cunderline%7BQ%27%20%3D%20%280%2C%20%5C%2C%201%29%7D)
Reasons:
The given rule for the dilation of QRST to the image Q'R'S'T' is presented as follows;
(x, y) = (0.5·x, 0.5·y)
The coordinates of the point Q' following a dilation of the point Q(0, 2) by
is therefore;
Q(0, 2)
(0.5 × 0, 0.5 × 2) = Q'(0, 1)
- The coordinates of
![\underline{Q' = (0, \, 1)}](https://tex.z-dn.net/?f=%5Cunderline%7BQ%27%20%3D%20%280%2C%20%5C%2C%201%29%7D)

Answer:
Profit % =50%
Step-by-step explanation:
Cost of 50 kg = sh 4000
Selling price of 1kg = sh 120
Selling price of 50 kg = sh 6000
![profit \% = \frac{Selling \ price - cost \ price}{cost \ price} \times 100\\](https://tex.z-dn.net/?f=profit%20%5C%25%20%3D%20%5Cfrac%7BSelling%20%5C%20price%20-%20cost%20%5C%20price%7D%7Bcost%20%5C%20price%7D%20%5Ctimes%20100%5C%5C)
![=\frac{6000 - 4000}{4000} \times 100\\\\=\frac{2000}{4000} \times 100\\\\=\frac{1}{2} \times 100\\\\=50 \%](https://tex.z-dn.net/?f=%3D%5Cfrac%7B6000%20-%204000%7D%7B4000%7D%20%5Ctimes%20100%5C%5C%5C%5C%3D%5Cfrac%7B2000%7D%7B4000%7D%20%5Ctimes%20100%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20100%5C%5C%5C%5C%3D50%20%5C%25)
