Answer:
she invested 6600 at 3% and 3400 at 2.5%
Step-by-step explanation:
Simple interest = amount deposited x time x interest rate
Let the amount deposited in in the account bearing 3% interest by represented with a
Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)
a x 0.03 + (10,000 - a) x 0.025 = 283
0.03a + 250 - 0,025a = 283
collect like terms
0.03a - 0.025a = 283 - 250
0.005a = 33
a = 6600
the amount deposited in the 2.5% account = 1000 - 6600 = 3400
Answer:
The triangle with side lengths 7 in, 11 in, 13 in will be an acute angled triangle.
Step-by-step explanation:
If we assume that the triangle with height 7 inches and base 11 inches of a right triangle then its hypotenuse will have the length of
inches.
But the third side of the triangle is given to be 13 inches which is less than 13.04 inches i.e. 13 < 13.04.
Therefore, the triangle with side lengths 7 in, 11 in, 13 in will be an acute-angled triangle. (Answer)
Answer:
A 45/28
Step-by-step explanation: because a tangnt means a a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point. so 45 and 28 are on it so it has to be A
Part 1 :Using a variable, write an expression that describes the total amount of money earned by both boys at the end of the month.
Let the number of lawns mowed be = x
Earnings of Amar = 20x
Earnings of Sang = 15x
So total earnings are =
Part 2: Amar and Sang mowed 10 lawns each by the end of the month. They need $400 for a summer trip. Do they have enough money for their trip?
Total number of lawns mowed by each are = 10
Amar earned =
Sang earned =
So, total money earned = = $350
No, they don't have enough money for their trip. They are short of $50.
The number is assumed to be x
x of 40% = 56
x * (40/100) = 56
x = 5600 / 40
x = 140
