Answer:
2992 or 2112
Step-by-step explanation:
$1,000 times 10% (0.1) = $100
$1,200 in a year.
$2,400 in a year + $1,000 originally = $3,400.
$3,400 * 0.12 = $408
#3,400 = $408 = $2,992.
Or..
$2,400 * 0.12 = $288
$2,400 - $288 = $2,112.
Answer:
Step-by-step explanation:
39²=1521
80²=6400
39²+80²=1521+6400=7921
87²=7569
7921≠7569
so it is not aright angled triangle.
I don't really know what the question is that needs to be solved, but
here's a suggestion that might help:
Since there are seven days in a week, you could multiply 25 milligrams
by 7, and that will tell you the number of milligrams in a whole week.
(-9x-6y=-54) +(8x+6y=50)= -x=-4; x=4
3(4)+2y=18
12+2y=18
2y=6 ; y=3
Each birthday card costs 4
Answer:
The base of the ladder has a length of 8 ft.
Step-by-step explanation:
We have to draw a triangle, as the figure attached.
The hypothenuse of the triangle is the length of the ladder (17 ft).
The height on the wall that the ladder reach is the adjacent (15 ft).
The base of the ladder is our unknown quantity X.
We will use the Pythagorean theorem to express the relation between these numbers:
The base of the ladder has a length of 8 ft.
