Use the relation 2x+y=10 to find the missing values.​

Answers

Answer 1

Answer:

x= 5 -y/2

y=10-2x

Step-by-step explanation:

solve for Y                solve for X        

2x + y= 10                   2x+ y=10              subtract y from each side

-2x        -2x                       -y=10 -y

       y=10-2x                    2x=10 -y

                                        2x/2=  10 -y/2  multiply both sides by 2

                                              x= 5 - y/2

One of the largest swimming pools in the world is in Garden City, Kansas. It is rectangular and
measures 67 meters by 100 meters. If you swim diagonally across the pool, how many meters would
you swim? Round your answer to the nearest whole meter

Answers

Answer:

The answer is 7,000 meters

Step-by-step explanation:

because you do 67*100 which equals to 6,700 and then u round it which makes it equal to 7,00 meter

Answer:

120 meters (approx)

Step-by-step explanation:

Think of the rectangle like two triangles;

if we find the hypotenuse of one, then we know the length of the rectangle across

Remember the Pythagorean theorem:

a^2 + b^2 = c^2

where a and b are the sides of the triangle

so then substitute in the known values:

a = 100

b = 67

now solve

100^2 + 67^2 = c^2

14489 = c^2

sqrt(14489) = c

120.37 = approx c

Suppose y varies directly with x. If y = 6 when x = 18, find the value of y when
x= 8.

Answers

Answer:

y = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition

y = 6 when x = 18 , then

6 = 18k ( divide both sides by 18 )

k = [tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex]

y = [tex]\frac{1}{3}[/tex] x ← equation of variation

When x = 8, then

y = [tex]\frac{1}{3}[/tex] × 8 = [tex]\frac{8}{3}[/tex]

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?

Answers

Answer:

Girls = 390

Step-by-step explanation:

Set up a proportion:

In a sample of 3:2, you have 5 kids in all.

So the the ratio of girls to kids in a sample of 5 is 2:5.

So set up a proportion:

(3/5) = (x/650)

5x = 650(3)

5x = 1950

x = 390

Answer:

390

Step-by-step explanation:

Let number of boys be b and girls be g. Then we have:

g/b = 3/2g + b = 650

From the first equation b is:

b = 2g/3

Substitute b in the second equation

g + 2g/3 = 6505g/3 = 650g = 650*3/5g =  390

Consider these situations. In each situation, is the demand for the good elastic or inelastic?



BLANK As the price of flat-screen televisions decreases, the quantity demanded increases significantly.



BLANK As the price of bread decreases, the quantity demanded changes only slightly.



BLANK As the price of a drug used to treat heart disease increases, the quantity demanded remains unchanged.

Answers

Answer:

1 elastic

2 inelastic

2 inelastic

Step-by-step explanation:

edge 2021, hope this helps

Here are the elasticities of demand in the following situations :

The demand for flat-screen is elastic.

The demand for bread is inelastic.

The demand for drug is perfectly inelastic.

Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.

Price elasticity of demand = percentage change in quantity demanded / percentage change in price  

Types of elasticity of demand are :

1. Elastic demand : If the absolute value of price elasticity is greater than one, it means demand is elastic. Elastic demand means that quantity demanded is sensitive to price changes.  

If demand is elastic and price is decreased, quantity demanded would increase. The increase in quantity demanded would be greater than the decrease in demand and this would lead to an increase in revenue.

2. Inelastic demand : Demand is inelastic if a small change in price has little or no effect on quantity demanded. The absolute value of elasticity would be less than one.

3. Unit elastic demand : Demand is unit elastic if a small change in price has an equal and proportionate effect on quantity demanded.

4. Perfectly elastic demand : when demand is perfectly elastic, demand falls to zero when price increases

5.Perfectly inelastic demand :  demand is perfectly inelastic when there is no change in the quantity demanded regardless of changes in price.

The demand for flat-screen is elastic. This is because when the price of the television was decreased, demand increased significantly

The demand for bread is inelastic. This is because the fall in quantity demanded was less than than the decrease in the price of bread

The demand for drug is perfectly inelastic. This is because there is no change in the quantity demanded when the price of the drugs was increased.

Answer:

y + 1 = -3(x + 2)

Step-by-step explanation:

Point-slope form is y - y1 = m(x - x1)

m= -3  (-2, -1)

Plug -3 in for the m in the equation, -2 in for x1, and -1 in for y1

y - (-1) = -3(x - (-2))

Subtracting negatives will make them positive

y + 1 = -3(x + 2)

This is the point-slope form, continuing to solve for y will give the y-intercept form.
