Which is bigger 6.6 or 0.78 ? 6.6 is bigger =================== x^2 - x......when x = 2 2^2 - 2 = 4 - 2 = 2 <== ==================== A = bh 60 = 10h 60/10 = h 6 = h....so height is 6 m ==================== 900 decreased by 5% = 900 - 0.05(900) = 900 - 45 = 855 <== ===================== 2(x + 3) = 8 2x + 6 = 8 2x = 8 - 6 2x = 2 x = 2/2 x = 1 <== ======================= 360 in a ratio of 1 to 4.....
1:4......added = 5
1/5(360) = 360/5 = 72 4/5(360) = 1440/5 = 288
ratio is 72:288 ======================= 3,8,13,16,23.....this is an arithmetic sequence with a common difference of 5
the nth term : an = a1 + (n - 1)d an = 3 + 5(n-1) <=== ====================== are there decimals in this problem......because the angles of a quadrilateral , when added = 360 degrees ====================== 75% = 66....what is full cost... 75% of what is 66.. 0.75x = 66 x = 66 / 0.75 x = 88 <== ===================== y = 4x - 1...when x = -2 y = 4(-2) - 1 y = -8 - 1 y = -9 <== ====================== 6.5 ???? cant see the problem ====================== circumference of circle with radius of 4..... C = 2(pi)r C = 2(3.14)(4) C = 25.12 cm <== or C = 8*(pi) ===================== 6 km / h for 2 hrs 20 min...
6 / 60 = 0.1 km per minute......0.1(140) = 14 km <== ===================== to increase an amount by 4.6%, ur multiplier would be 1.046 ===================== (x - 5)(x + 4) = x^2 + 4x - 5x - 20 = x^2 - x - 20 <=== ====================== 500 increased by 4.6%.... 500(1.046) = 523 <== ======================= 2x > 7 x > 7/2 or x > 3.5 ====================== 500 tickets are sold.....probability of winning first prize (if there is only 1 first prize) is 1/500....dont know how many tickets he bought ====================== 6 * 0.6 = 3.6......u simply multiply 6 * 6 = 36....and since 0.6 has a decimal 1 space to the left, in ur answer(36)...move the decimal 1 space to the left giving u 3.6 ======================= 5x - 2y....when x = -2, y = -3 5(-2) - 2(-3) = -10 + 6 = -4 <== ======================= 0.521 to one significant figure = 0.5 ======================= 4,7,13,22,34...... 4 to 7 = 3 spaces 7 to 13 = 5 spaces 13 to 22 = 9 spaces 22 to 34 = 12 spaces I am sorry....I do not know this one..cannot find the pattern ======================= V= bh V = 3*10 V = 30 not sure about this...because volume of a prism is base * height....there is o (pi) in the formula. ===================== 7.34 * 4.71 = 34.5714 rounds to 34.57 5.63 + 11.89 = 17.52 ==================== y = x^2 + 2x......x = -2 y = -2^2 + 2(-2) y = 4 - 4 y = 0 <==
i hope this answer helps you!
