Step-by-step explanation:

answer:

step by step explanation

Note the second diameter was used as 50cm and not 500cm

given

F1=800N

D1=20cm

A1=πD1^2/4

=3.142*20^2/4

=314.2cm^2

D2= 50cm

A2=πD2^2/4

=3.142*50^2/4

=1963.75cm^2

The pressure applied on the smaller relative to the bigger end is expressed as

F1/A1=F2/A2

substitute we have

800/314.2=F2/1963.75

cross multiply we have

F2=800*1963.75/314.2

F2=1571000/314.2

F2=5000N

F2=5kN

The larger Force is 5kN

Answer:

t = -1/8.

Step-by-step explanation:

t / 5/12 = -3/10          Invert the 5/12 and multiply:

12t / 5 = -3/10

Cross multiply:

12t * 10 = 5 * -3

120t = -15

t = -15/120 = -1/8.

Answer:

Whats the area or perimeter?

Answer:#1.

A=the amount of miles traveled and gallons of fuel

B=Y is the first one it is the amount of miles traveled

C=30x 150

#2.

A=3x 602

B=height of tree inches

C= the number of months

Step-by-step explanation:

i have already had this question

Answer:

35.7 gallons

Step-by-step explanation:

Given that:

Distance traveled = 700 miles

Gasoline used = 25 gallons

The gallons of gasoline used are directly proportional to the number of miles traveled.

To find the gallons of gasoline to be used after driving 1000 miles, we can use the unitary method in which we first of all find, how much gallons of gasoline would be used for 1 mile and then multiply the value with 1000 to find the answer.

700 miles are traveled by gallons of gasoline = 25

1 mile is traveled by gallons of gasoline = [tex]\frac{25}{700}[/tex]

1000 miles are traveled by gallons of gasoline = [tex]\frac{25}{700}\times 1000 = \bold{35.7\ gallons}[/tex]

bob is older than fred with 3 years so when bob was born the fred didn't even exist

but im not sure

Answer:

C

Step-by-step explanation:

im pretty sure it this because it would make 180 degrees ;-;

Answer:

20 degrees

Step-by-step explanation:

angles on a straight line/ straight line angles/ supplementary angles = 180 degrees

angle 1 + angle 2 = 180 degrees

160 + angle 2 = 180

angle 2 = 180 = 160

angle 2 = 20 degrees

Answer:

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The required explanatory variable is concentration of active ingredients. Option D is correct.

Given that,
From the paragraph, "Medical researchers studying a medication in male and female patients 20 to 29 years old noticed that, up to a certain amount, a larger concentration of an active ingredient lead to greater levels of symptom relief." it is to be determined which is an explanatory variable.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
A) age of patient = Not explanatory

B) gender of the patient = Not explanatory

C) amount of symptom relief = Not explanatory

D) concentration of active ingredient =  Explanatory

Thus, the required explanatory variable is the concentration of active ingredients. Option D is correct.

Bonnie is making a dipping sauce. She mixes 150 milliliters of soy sauce with 100 milliliters of vinegar. How much soy sauce does Bonnie mix with every 1 milliliter of vinegar?

Answer:

1.5 mm soy sauce

Step-by-step explanation:

Bonnie is making a dipping sauce. She mixes 150 milliliters of soy sauce with 100 milliliters of vinegar. How much soy sauce does Bonnie mix with every 1 milliliter of vinegar?

Hence:

100 mm vinegar = 150mm soy sauce

1 mm vinegar = x

Cross Multiply

100 × x = 150 × 1

x = 150 × 1/100

x = 1.5 mm soy sauce

Hence, Bonnie mixes with every 1 milliliter of vinegarwoth 1.5 mm soy sauce

Answer:

m<L = [tex]33.9^{o}[/tex]

Step-by-step explanation:

Triangle JKL is an isosceles triangle, given that <J ≅ <L. An isosceles triangle has two of its angles and sides to be equal.

The exterior angle formed = [tex]67.8^{0}[/tex]

But,

<J + <L = [tex]67.8^{0}[/tex] (the sum of two opposite interior angles is equal to the exterior angle)

Let <J ≅ <L be represented by a, so that;

a + a =  [tex]67.8^{0}[/tex]

2a = [tex]67.8^{0}[/tex]

a = [tex]\frac{67.8^{o} }{2}[/tex]

  = [tex]33.9^{o}[/tex]

The measure of <L is m<L = [tex]33.9^{o}[/tex] (m<L =

Thus,

m<J ≅ m<L = [tex]33.9^{o}[/tex]
