1.) total quantity of video games on the way to be played: 75+45 = 120 The team desires to win 60%. 60% of a hundred and twenty = 120*zero.6 = seventy two games number of games received to this point: 50 number of video games but to win: 72 - 50 = 22 2.) field of the rectangle = length*width = eight*12 = ninety six discipline of the triangle = 0.5 * base*altitude = ninety six which means that: base*altitude=192 altitude = 192/32 = 6 three.) quantity of scholars in school: 18*35 = 630 quantity of classes needed for 630 scholars: 630/30 = 21 number of classes current: 18 number of classes that need to be shaped: 21-18=three four.) The answer is A. 5.) Slope=(y2-y1)/(x2-x1) = (three-4)/(0-5) = 1/5 6.) One kilometer= b.) 1,000,000 millimeters 7.) determine for (1, 5): 3*1-5=-2 =/= 2 (1, 5) just isn't on the road, so a), b) and d) are improper. Examine for (2, four): 3*2-4 = 6-four = 2 determine for (three, 7): 3*three-7 = 9-7 = 2 So c) is the correct answer. 8.) 3x-1=eleven 3x = 12 x = four x^2+x = 4^2 + four = sixteen + four = 20 9.) For all bells to ring, we need a number of hours to pass that divides by using 2, four, and three. The bottom such quantity is 3*4=12. 9 am + 12 hours = 9 pm 10.) percent of revenue saved: a hundred - 20 - 23 - forty two = 15% If 15% is $360, the whole revenue is $360*a hundred/15 = $2 400 eleven.) subject of stroll: 6*24 = one hundred forty four feet^2 area of brick: (1/3)*(2/three) = 2/9 toes^2 quantity of bricks needed: a hundred and forty four/(2/9) = 648 12.) 2x+3>7 2x>4 x>2 0 is the only number on the record that is <2, so the answer is a). Thirteen.) The room has 2 wall with the subject length*height and a pair of walls with the discipline width*peak. The complete subject of the partitions: 2*24*9 + 2*18*9 = 432 + 324 = 756 14.) length of spoke = diameter/2 In first wheel: 28/2 = 14 In 2d wheel: 21/2 = 10.5 change: 14-10.5 = 3.5 15.) Frank makes 21/4 machine materials per hour, so in 7 hours he's going to make (21/four)*7 = 21*7/four parts. Sixteen.) e.) now not adequate expertise is given It says he divided the rest inconsistently, nevertheless it would not say who got what percent. 17.) 228/35 = 6 (18) seeing that the 18 persons that stay may also desire a tour director, the number of tour administrators needed is 7. 18.) b.) (14900-(750+1250)) /60 19.) 1000th = 0.001 Eight thousandths = 0.008 (a)) 20.) d.) 4.9 21.) d.) 2023 22.) d.) 300.021 23.) 2 three/four + eight half = eleven 1/four
