Answer:
3.2%
Step-by-step explanation:
-Let r be the simple interest rate per annum.
-Given the total amount after 1 year is 1857.60, the initial amount is 1800
#We use the simple interest formula to find the rate of interest:

Hence, the annual interest rate on the deposit is 3.2%
X and w is 105 degrees and y and z are 86 degrees. since line L is a straight line it would have to add up to 180 and same with line M
Your answer is going to be 5x^2+6 because if you simplify and do x(5)x +6 it will equal to 5x^2 + 6
Hope this helped!!
Answer:
660
Step-by-step explanation:
Let A = number of buttons in Box A
and B = number of buttons in Box B
We have two conditions:
(1) A + B = 1200
(2) B + 360 = 3(A – 360) Remove parentheses
B + 360 = 3A - 1080 Subtract 360 from each side
(3) B = 3A - 1440 Substitute (3) into (1)
A + 3A - 1440 = 1200 Combine like terms
4A - 1440 = 1200 Add 1440 to each side
4A = 2640 Divide each side by 4
A = 660
Answer:
theese are supplementary angles as their sum is greater than 180
Step-by-step explanation:
supplementary angles: angles whose sum is <180
complementary angles: 2 angles whose sum equals 90 degrees
vertical angles: opposite angles
