Answers

Answer 1

Answer:4

Step-by-step explanation:if you replace each "x" in the equation with the given x (-15) then it should go as such:

2(-15-5)-(3(-15)+1)

Then simplify

2(-20)-(-45+1)

2(-20)-(-44)

-40-(-44)

The gallons of gasoline used on a car trip varies directly as the number of miles driven. If 25 gallons of gasoline has been used after driving 700 miles,how many gallons of gasoline would be used after driving 1000 miles? Round your answer to the nearest tenth

Answers

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]

Answers

Complete Question

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

In Triangle JKL, ∠J is congruent to ∠L. Triangle J K L is shown. Ray L K extends beyond point K to form an exterior angle that is labeled sixty-seven and eight tenths degrees. What is the measure of ∠L? Enter the correct answer in the box.

Answers

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]

B) gender of patient
C) amount of symptom relief
D) concentration of active ingredient

Answers

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.

What is simplification?

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.

Calculate the force output by the larger piston of a hydraulic lift when a force of 800 N is exerted on the smaller piston. The areas of the two pistons are 20 cm2 and 500 cm2.

Answers

answer:

F2= 5kN

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
