X * 8/100 * 1 + 9/100 * (11,000 - x) = 980
0.08 x + 0.09 (11000 - x) = 980 Now solve for x which is the amount invested at 8%
0.08x + 990 - 0.09x = 980
- 0.01x = 980 - 990 = -10
x = -10 / -0.01
x = 1000
So he invest 1000 in 8% and 10000 at 9%
Answer:
$14.99
Step-by-step explanation:
395 + 499 + 605 =1499
Slope-Intercept form is y=2x+2 because it takes 2 x's to move before 1 Y moves. and +2 because it is 2 places up on the Y intercept
A kite is a quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” means that one side can’t be used in both pairs).
Then:
- Two disjoint pairs of consecutive sides are congruent by definition - QP≅QR and QR is not congruent to RS (one side can’t be used in both pairs);
- One diagonal (segment QS, the main diagonal) is the perpendicular bisector of the other diagonal (segment PR, the cross diagonal), so PM≅MR;
- The opposite angles at the endpoints of the cross diagonal are congruent, thus ∠QPS≅∠QRS.
- ∠PQR is not congruent to ∠PSR, because they are not angles at the endpoints of the cross diagonal.
Answer: correct options are A, B and E.
The answer should be letter B.
