Answer:

Step-by-step explanation

Using the formula: A= base1 + base 2/ 2 *h

The base you are looking for will be named a;

a = 2 a/h - b 2*112/8 - 11 =17

first a is base a. = 2 times area divided by height minus base b which is 2 times 112 over 8 minus 11 which gives you the answer of 17

Answer: The answer is 17

Step-by-step explanation: The equation for a trapezoid is a= a+b divided by 2 x hight

if the area is 112 you must divide it by 8 the hight which gets you 14 then times 14 by 2 which gets you 28 so if you do 11+17 it gets you 28 once done check it by pluging in 17 into the equation as b and

A business man mixed high quality sugar costing 10 shillings with low quality sugar costing 8 shillings per kg in the ratio 3:5

11111nata11111 [884]

Answer:

His percentage profit is 12%

Step-by-step explanation:

Here, we want to calculate the percentage profit made by the business man.

Per kg of what he is selling, he has 3 parts high quality sugar and 5 parts low quality sugar.

Now let’s see how much these costs

For the high quality sugar, it’s total kg mixed per kg will be 3/(3+5) = 3/8

Since high quality sugar costs 10 shillings per kg, 3/8 of a kg will cost 3/8 * 10 = 30/8 = 3.75 shillings

For the low quality, its part will be 5/(3 + 5) = 5/8

since low quality costs 8 shillings per kg, 5/8 of a kg will cost 5/8 * 8 = 5 shillings

Total cost price = 3.75 + 5 = 8.75 shillings

% profit = (selling price - cost price)/cost price * 100%

selling price here is 9.8 shillings per kg

while cost price is 8.75 shillings per kg

% profit = (9.8-8.75)/8.75 * 100%

= 1.05/8.75 * 100% = 0.12 * 100% = 12%

Circle A was translated 3 units to the left and 4 units up to create Circle B. Which rule describes the translation that was app

kifflom [539]

Answer:

$B = (x - 3, y + 4)$

Step-by-step explanation:

Given

Represent the coordinates of circle A with (x,y)

<u>Translation</u>

Left = 3 units

Up = 4 units

Required

Determine the coordinates of B

When a point (x,y) is translated by h units left, the new point is: (x - h, y)

When a point (x,y) is translated by b units up, the new point is: (x, y + b)

So, when circle A is completely translated to B, the new points of B is:

$B = (x - h, y + b)$

In this case:

$h = 3\ and\ b = 4$

So:

$B = (x - 3, y + 4)$

Work out 1 3/4+ 3 1/2

choli [55]

We can write,

1 3/4 as 7/4 & 3 1/2 as 7/2

So, 7/4 + 7/2 = 21 / 4 in fraction form.

OR 5 1/4 in mixed form.
