Answer:
Step-by-step explanation:
Area=1/2(bh)
b=x
height=2x-2, units meters
30=(1/2)bh
60=bh=x(2x-2)
2x^2-2x=60
2x^2-2x-60=0
x^2-x-30=0
(x-6)(x+5)=30
x=6 as only positive root.
2x-2=10
Their product is 60 m^2, half of which is 30 m^2
The base is 6 m; the height is 10 m.
First find slope
(2-4)/(3+1) = -2/4 = -1/2
Use point (3,2)
y-y1 = m(x-x1)
Plug everything in
y-2 = -1/2(x-3)
Solution: A
Total height of the cake and the candles is 17.1 cm
Step-by-step explanation:
- Step 1: Convert the mixed fractions into decimal expressions.
11 7/10 cm = 117/10 = 11.7 cm
5 4/10 cm = 54/10 = 5.4 cm
- Step 2: Find total height of the cake and the candles
Total height = 11.7 + 5.4 = 17.1 cm
It would be over 12% (11.98375085%)
Lets break it down:
You need to find what percent 177 is of 1,477.
To do this, you need to do 177÷1,477 to get 0.1198 and so on
(To find a percent from a decimal, you move the decimal point 2 places to the right)
If you find the percent, it would be 11.98 (and so on) percent. Rounded to the nearest 1%, it would be 12%
Hope this helps!
