Landen spent L hours at the beach last weekend. Matéo spent 15% fewer hours at the beach than Landen did
fenix001 [56]

Answer: B, D, and E

0.85L

or

L-0.15L

or

L(1-0.15)

or

L - \frac{15}{100}L

L - \frac{3}{20}L

Step-by-step explanation:

L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or \frac{15}{100}L. We subtract by L-0.15L or as L - \frac{15}{100}L. This fraction can simplify to L - \frac{3}{20}L

(PaperTowels)
DochEvi [55]

Answer:

<u>23 consumer.</u>

Step-by-step explanation:

Given:

Number Of Responses for Thirsty = 49

Number Of Responses for Clean = 24

Number Of Responses for Strong Ones = 15

Number Of Responses for PowerWash = 12

So,

The total number of Responses  = 49 + 24 + 15 + 12 = 100

So, the probability to prefer PowerWash = 12/100 = 0.12

For a group of 195 consumers:

prediction to prefer PowerWash paper towels = 0.12 * 195 = 23.4

So,

The number of consumers prefer PowerWash paper towels = <u>23 consumer</u>

The measure of angle KMJ??
Irina18 [472]
44

Assuming JM and LN are parallel, KMJ=MKN. MKN is part of a triangle where the other two values are defined (48 and 88). By subtracting these values from 180, we find the value of MKN is 44, which therefore is also the value of KMJ.
