Answer:
Dont eat your food too cold im suggesting
Step-by-step explanation:
First of all you can get a cold then you can get sick and food isnt good cold
Area=legnth times width
width=1/5
area=1/5 times width
area=4
4=1/5 times legth
multiply both sides by 5/1 to clear fraction (since 1/5 times 5/1=5/5=1)
remember ou can do anything to an equaiton as long as you do it to both sides
20=1 times legnth
20=legnth
answer is legnth==20 m
Answer:
Hi there!
The correct answer to this question is: 97/15
Step-by-step explanation:
First step is to change all the mixed fractions into improper fraction.
9 8/9 becomes 99/9 and 4 8/15 becomes 68/15
then you divide 99/9 you get 11. then you multiply 11 with 15 to get a common denominator. so now the equation is 165/15 - 68/15 which equals 97/15
Answer:
<em>100feet</em>
Step-by-step explanation:
Given the height of the object modelled by the equation
y = -16x^2 + 48x + 64
We can find the maximum height reached by the object since we are not told what to find.
The velocity of the object at its max height is zero.
dy/x = 0
dy/dx = -32x + 48
0 = -32x + 48
32x = 48
x = 48/32
x = 1.5secs
get the max height by substituting x = 1.5 into the given equation:
y = -16x^2 + 48x + 64
y = -16(1.5)^2 + 48(1.5)+ 64
y = -36+72+64
<em>y = 100 feet</em>
<em>Hence the maximum height reached by the object is 100feet</em>
Answer:
42%
Step-by-step explanation:
If the probability of the first machine breaking down is 30%, the probability of it operating normally is 100% - 30% = 70%
The probability of the second machine operating normally is 100% - 40% = 60%
So, the probability of both machines operating normally in one day is:
P = 70% * 60% = 0.7 * 0.6 = 0.42 = 42%
