Math Problems 2/24 and 2/25 to date Ms. Borg

2/24
























1. Out of every 100 numbers, Sara will write down 81 and 19 will be eliminated. For example, from 1–100 the eliminated numbers will be 9, 19, 29, 39, 49, 59, 69, 79, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, and 99. The pattern holds for every 100 numbers: 109, 119, 129…etc. The number 300 will therefore be the 243rd listed. There are 57 to go. But when 357 is reached, 309, 319, 329, 339 and 349 have been eliminated so there are still five to go. Sara lists 358, (skips 359), 360, 361, 362- then the 300th number on the list- 363.

2.   3_  _9     XX = 12

      1_    2_    4_ =  7

     XX  *5  _8_  =13
     4     16   12. TOTALS

3. FOUR TUESDAYS AND FRIDAYS MEANS 5 OF 3 OTHER DAYS (31 DAYS IN OCTOBER)
CANNOT BE WED AND THU (MISSING ONE) SO SAT ,SUN, MONDAY answer
4. 96 symbols, 97 starts the pattern again. so 100=♢ Diamond, 101=♡ Heart
5. P=6, S = 0, R=9, Q=1
 8100
-6092
 2008

2/25;












1.  C+I+4 = R + I can only be C= 9 and R=13 answer
    2. the difference multiplied is (54-45) i.e. 9; 198/9=22 answer 
check:22*54=1188; 22*45=990; 1188-990=198 checks.










3.  i) C+B = 9; ii) H+B=12; iii) H+C=18 boxes per hour
C-H=-3 subtract ii from I
H+C=18 (from iii), then add
2C.   =15, C=7.5 boxes per hour. Answer; 








Mean of 7 forces total of all to be 49
if the other 6 are 1,2,3,4,5,6 is the minimum total of the others = 21, the largest can be 28 answer.













I = 1 implies
2n + e = 8  (subtract t from both sides of the 2nd equation)
if e = 2, then 2n = 6; n=3
t+2+3 = 10, implies t=5 answer.

ELA The Integrity of Pineapple Pizza

The Integrity of Pineapple Pizza by Sarah Celestin, 16 For many years those who enjoy pineapple on their pizza have faced ridicule. Many people strongly disagree with the combination pineapple and pizza, and it is understood that not all opinions are always completely agreed on, but the perspectives of pineapple pizza eaters have been disrespected for far too long. The outright disgust expressed by non-pineapple pizza eaters is a contradiction to some of of the world’s favorite foods. For centuries various fruits,such as mango and watermelon, have been topped with salt and chili mixes, but the reaction to the list of concoctions previously stated do not even begin to compare to the reactions to pineapple pizza. Salted caramel, kettle corn, chocolate covered pretzels, peanut butter and jelly sandwiches: these are all snacks that are widely loved, but carry the same flavor profiles as pineapple pizza. So why is pineapple pizza so hated? Scientifically pineapple pizza stimulates two ...

CommonLit WHY ARE BEES VANISHING? Scientists find a combination of threats that may explain declining honeybee populations by Alison Pearce Stevens2014 Ms. Mulligan

Honeybees are an important part of Earth’s ecosystem—they pollinate plants, which produce food. Over the past ten years, researchers have been trying to figure out why so many honeybee colonies are collapsing.    As you read, find evidence to answer the following questions: Why are bees vanishing? How could this affect us? The post office is buzzing as package after package of honeybees await delivery to their new homes. The tiny hooked feet of some worker bees cling to the screens on the sides of each wooden case. Other worker bees huddle around a small central cage containing their queen. Sorting and delivering packages of live honeybees isn’t the favorite task of postal workers. Still, it is a job they have to handle more and more often. That’s because beekeepers in the United States and Europe have been losing bees to a mysterious condition known as colony1 collapse disorder, or CCD. Each mail-order package contains the seed of a new honeybee colony to replace one t...
