Answer:

hope this help !

Step-by-step explanation:

An expression is shown below.
Natalka [10]

Answer:

see step-by-step

Step-by-step explanation:

It's not clear from your notation, so I will provide 2 answers.

3√(47x) = 24√(47)

3√(47)√x = 24√(47)

Divide both sides by √(47):  3√x = 24

Divide both sides by 3:  √x = 8

Square both sides:   x = 64

3√(47)x = 24√(47)

Divide both sides by √(47):  3x = 24

Divide both sides by 3:  x = 8

F is inversely proportional to d^2.
Doss [256]

Answer:

11.6

Step-by-step explanation:

F = k/ d^2

where k = proportionality constant

k = Fd^2

k = 5 * 9^2

k = 5*81 = 405

d = (K/F)^1/2

d = (405/3)^1/2

d = 11.62 =11.6

Help. Does anyone know how to do this?
tatuchka [14]

Answer:

x = 12, so PTQ = 40 deg

Step-by-step explanation:

first, because the two are vertically opposite, they are equal, write a formula for this:

x + 28 = 2x + 16 (minus 2x from both sides)

-1x + 28 = 16 (minus 28 from both sides)

-1x = -12 (divide both sides by -1)

x = 12

sub into formula:

12 + 28 = 40

Umnica [9.8K]

Answer:

No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.

Step-by-step explanation:

At Lawson Middle School, Mr. Hernandez asked 90 randomly selected students from each grade level for their favorite subject.

   90 randomly selected students from each grade level for their favorite subject, and 28 chose social studies as their favorite.

so, the percent of students who love social studies is given by:

28/90 x 100=31.11%

   He used this data to draw the inference that out of the 250 middle school students, about 20% prefer social studies.

No, Mr. Hernandez’s sample is random, not biased, large enough compared to the population, but 28 is not 20% of 90.
