Answer:
the answer is P= F/(1+r)^t
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
25 = 1/2(3 + 7)h
5 feets
Step-by-step explanation:
Given that:
Window shaped in the form of a trapezium :
The length of its bases :
Top of window base = 3 feets
Bottom of window base = 7 feets long
Area of Windom = 25 feets²
Recall :
Area of a trapezium is given by :
Area, A = 1/2(a + b)h
a and b are the bases
h = height
Inputting the Given values into the equation :
25 = 1/2(3 + 7)h
Hence, the height of the window can be Obtian using the expression
25 = 1/2(3 + 7)h
25 = 1/2(10)h
25 = 5h
h = 25 /5
h = 5 feets
Answer:
15/10
Step-by-step explanation:
Since it is adding you need to get a common denominator(bottom number).
I know that 2 × 5 = 10 so now we multiply 3/5 × 2
we get 6/10
now the problem is 9/10 + 6/10
9 + 6 = 15 and the denominator is 10
15/10
Answer:
25 pages
Step-by-step explanation:
Create a proportion:
= 
= 
Cross multiply and solve for x, the number of pages in 75 minutes:
60x = 1500
x = 25
So, he can read 25 pages in 75 minutes at the same rate
Answer:
4% sales tax
Step-by-step explanation:
Take the original costs and subtract it from the price after sales tax.
$84.24-$81= $3.24
Divide 3.24 by 81
this gives you .04, now either multiply by 100 or move the decimal two places to the right to convert the decimal to a percentage.
