Answer:
The area of figure ABCD is 24 square units.
Step-by-step explanation:
We see that the given points form the vertices of a trapezium ABCD with bases AD and CB with measure,
AD= 3 units and CB=5 units
and the height of the trapezium is AB= 6 units.
The area of trapezium ABCD is:
Answer:
Volume= 180
Step-by-step explanation:
The formula for finding the volume of a triangular prism is V= LWH divided by 2. L=Length W=Width H= Height So (12)(6)(50)= 360 divided by 2 is 180.
The amount she will have left is $10,500
<h3>How to calculate tax and earning</h3>
Given the foliwng paramters
Total amount earned by the student = $15000
Assume we have the following parameters
Earning paid off in taxes = $1500
Amount spent on living expenses = $3000
Amount she will have left = 15000 - (1500 + 3000)
Amount she will have left = 15,000 - 4500
Amount she will have left = 10,500
Hence the amount she will have left is $10,500

Volume of first oil = A, volume of second oil = B, volume of mixture = M
A = ?, B = 4l, M = A + B
40%A + 25%B = 30%M
40%A + 25%4l = 30%(A+4l)
<span>40%A + 25%4l = 30%A + 30%4l
40A + 100l = 30A + 120l
40A - 30 A = 120l - 100l
10A = 20l
A = 2l

Answer: 2 litres of 40% oil dressing.
Also note: That's an approximation, because the volumes are not strictly additive. For example: mixing 50ml pure ethanol with 50ml water will give you about 95ml of mixture. To get an accurate answer, you'd have to measure the volume of the final mixture and then divide your total oil content by that<span>.</span>
