Answer 1

Answer:

{y,x}={1,3}

Step-by-step explanation:

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Find the measure of the complementary angle for letter S, 14 degrees.

Answers

Answer:

The complementary angle for letter S will be: 76°

Step-by-step explanation:

As we know that two angles will be complementary if their measures add to 90°.

Given the angle of letter S = 14°

Let suppose the other measuring complementary angle is m∠A.

so the equation becomes

14° + m∠A = 90°

m∠A = 90° - 14°

= 76°

Therefore, the complementary angle for letter S will be: 76°

Shannon's new car sold for $28,000. Her online research indicates that the car will depreciate exponentially at a rate of 5 ¼ % per year. Write the exponential depreciation formula for Shannon's car.

Answers

Answer:

P = 28,000(0.945)^y

where P is the price of the car after y years of purchase

Step-by-step explanation:

The rate of decrease is 5 1/4 % per year

This is same as 5.5% (5.5/100 = 0.055) per year

The exponential equation will be ;

P = 28,000( 1 - 0.055)^y

P = 28,000(0.945)^y

where y is the number of years after the year of purchase

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]

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
