Answer:
1.25cm
Step-by-step explanation:
<em>Complete question:</em>
The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section
<em>length=7cm</em>
<em>width = 4cm</em>
<em></em>
The volume of the prism is expressed as;
Volume = Base Area * Height
Given
Volume of the prism = 35cm^3
Base Area = length * width
Base Area = 7cm * 4cm
Base Area = 28cm^2
Substitute the given values into the formula
35 = 28* Height
Cross multiply
35 = 28 * Height
35 = 28 Height
Height = 35/28
Height = 1.25cm
Hence the height of the triangular cross section is 1.25cm
It is D. 35 units I hope this helped ^^
To get the area, all you have to do is multiply the sides. 7*5=35
The nominal exchange rate (NER) is given by:
NER = RER × (foreign price / US price)
= 3/4 × ( 6 / 3)
= 3/2
In fact, with 1$ you can buy 1/3 of a US gallon, which corresponds to 1/4 of a foreigner gallon, which you would pay 3/2units.
Hence, the correct answer is a) <span>3/2 units of country A's currency per dollar.</span>
First you have to remember that to find a percentage you can multiply a number by the percentage's decimal form, for example 40% of 100 would be .40 * 100.
Anyways, 24*.40 =9.6.
To find the percentage however, you must divide 24/40 which equals 0.6, which is equal to the percentage 60%.
To find the third question, you must multiply 24 by 2.5 (0.4 * 2.5 = 1) and you should get 60.
The last question you may have made a typo on, you repeated the first question.
