Orange juice a raisin bagel and a cup of coffee cost 3.35 the orange juice will increase 50% and bagels will increase 20% after increase same purchase will cost 4.20, and the orange juice will cost twice as much as coffee. how much was the orange juice, bagel and coffee before increase
the answer is b. m∠ pos + m∠ por = 180
because if you already know that m∠poq equals 90 because it is a right angle
then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45
now you have the measurement for the two acute angles 45
which makes m∠pos = 45 and m∠qor =45
now you have to add 90 and 45 and 45 all together then you will have 180
3rd box is the answer
hello from mrbilldoesmath!
consider this example:
3 ^ 4 = 3 * 3 * 3 *3 = 81
but it also equals
(1/3) ^ (-4) = 1 / ( 1/3)^4 = 1 / (1/81) = 81
the exponent appears in the denominator. is this what you meant?
