Answer:
27.91 pretzels.
Step-by-step explanation:
Knowing that 1/3 of 33 bakers can make 89 pretzels in 2 1/2 hours, to determine how many pretzels can 5 3/4 bakers make in 1 1/2 hours the following calculation must be performed:
33 x 1/3 = 11
89 / 2.5 / 11 = X
35.6 / 11 = X
3.236 = X
3/4 = 0.75
3.236 x 1.5 x 5.75 = X
4.854 x 5.75 = X
27.91 = X
Therefore, 5 3/4 bakers can make 27.91 pretzels in 1 1/2 hours.
Answer:
576 adults
Step-by-step explanation:
The 5 part of the ratio relates to 720 children, then
720 ÷ 5 = 144 ← value of 1 part of the ratio , then
4 parts = 4 × 144 = 576 ← number of adults
Answer:
f(5) = 38
Step-by-step explanation:
f(a) = 7(a + 1) - 4
f(5) = 7(5 + 1) - 4
f(5) = 7(6) - 4
f(5) = 42 - 4
f(5) = 38
Answer:
neither; perpendicular; parallel; neither; neither
Step-by-step explanation:
parallel line is where the 2 slopes have same gradient and perpendicular means the two lines have a -1 slope when producted

Answer:
0.11
Step-by-step explanation:
Probability that house sale will increase = P(A) = 0.25
Probability that interest rate on house loans will go up = P(B) = 0.74
Probability that either house sales will go up or interest rates will go up = P(A or B ) = 0.89
We have to find the probability that neither house sales nor interest rates will increase. This event is the compliment of the event that either house sales will go up or interest rates will go up.
i.e.
Probability that neither house sales nor interest rates will increase = 
Using the value of P(A U B), we get:
The probability that neither house sales nor interest rates will increase during the next 6 months is 0.11
