Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains. Let d

Answer:

32d

Step-by-step explanation:

-The students ride their bikes to and from school every day. The distance is thus;

d_t=2d

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days

Now, we multiply the distance per day by the total number of days:

Distance, D=2d\times 16\\\\=32d

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).

Ok so it's a proportion so this fraction is to this fraction. the smaller rectangle has sides 4 and 12. the larger one has 8 and x. so u set it up 4/12=8/x. the 4 and 8 r both the short sides so u want those on top and 12 and x r long sides so those on bottom. since that is not an answer option u can set it up as 8/4=x/12 because u still keep the variables of the same rectangle from being multipled with each other. so answer #2 is correct

The jewerly store is having a sale. Necklaces that were regulaey priced at $23.50 are on dale for $18.80. What is the percentage
AveGali [126]
What we need to do is find the difference between the two numbers to find the difference in price and then figure out what the percent of 23.5 that is

23.50-18.80=4.7

now we'll set up a proportion

4.7       x
----- = -----
23.5   100

then cross multiply and divide

100×4.7=470/23.5=20

the percent of decrease is 20%

I hope I've helped!
