Answer:
50 grams
Step-by-step explanation:
Let the amount of cheese required by the recipe be "x"
Ann increased 60% from original amount and then used up 80 grams. Thus:
<em>Original, increased by 60%, became 80</em>
<em />
This translated to algebraic equation would be:
x + 0.6x = 80
<u>Note:</u> 60% = 60/100 = 0.6
So we can solve the above equation for "x" and get our answer. Shown below:
Hence,
the recipe required 50 grams of cheese
Answer:
Step-by-step explanation:
There are 1000 m in 1 km, and 3600 s in 1 h, so the speed conversion is ...
The car's speed is 90 km/h.
__
In 2 hours, the car will travel ...
distance = speed · time = (90 km/h)(2 h) = 180 km

The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
(3.5) (14) + 2</span><span>
(3.5)^2
If we simplify this expression, we get:
98</span><span>
+ 24.5</span><span>
If you simplify once more, you get
122.5</span><span>
or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span>
or about 384.85<span>
