Answer:
7/10 or 0.7
Step-by-step explanation:
The first step that you need to do is to convert 5.6 to a fraction. 5.6 can be rewritten as 
, which is equal to 
.To multiply two fractions together, you simply need to multiply together the numerators and then the denominators. 
. Hope this helps!
Answer: 2years, 5 months
Step-by-step explanation:
Principal, P = $6000
Rate, R = 3%
Interest, I = $450
Time, T =?
Simple Interest, I = P x T x R/ 100
making T, subject of formula
T = 100 x I/ P x T
Substituting the values into the equation,
T = 100 x 450/ 6000 x 3
T = 45000/ 18000
T = 2.5years = 2years, 5 months
Answer:
y = 5x + 4
Step-by-step explanation:
The slope always goes before the x and your y-intercept is plus or minus depending on weather it is positive or negative. Your parent function or standard equations) is y = mx + b, so just plug your variable into there.
Answer:
length = 78 m , width = 27 m
Step-by-step explanation:
let w represent width then length l = 3w - 3
the perimeter (P) is calculated as
P = 2l + 2w = 210 , substitute values
2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side
6w - 6 + 2w = 210
8w - 6 = 210 ( add 6 to both sides )
8w = 216 ( divide both sides by 8 )
w = 27 and l = 3(27) - 3 = 81 - 3 = 78
Then length = 78 m and width = 27 m
Answer:
There are 0.005 hundreds in 5/10.
Step-by-step explanation:
Claire drew model of 5/10
We want to know how many hundreds are in 5/10.
Let us use an obvious example.
There are three 2's in 6 right?
Suppose we didn't know this, and we are told to find how many 2's are in 6, we get this by representing this in an algebraic expression as:
There are x 2's in 6. This can be written as
2x = 6
Solving for x, by dividing both sides by 2, we have the number of 2's that are in 6.
x = 6/2 = 3.
Now, to our work
We want to find how many hundreds are in 5/10. We solve the equation
100x = 5/10
x = 5/1000 = 0.005
There are 0.005 hundreds in 5/10.
