A landlord owns 3 condominiums, a l-bedroom condo, a 2-bedroom condo, and a 3-

bedroom condo. The total rent she receives is $1240. She needs to make repairs on the

condos, and it costs 10% of the 1-bedroom condo's rent for its repairs, 20% of the 2-

bedroom for its repairs, and 30% of the 3-bedroom condo's rent for its repairs. The total

repair bill was $276. The 3-bedroom condo's rent is twice the 1-bedroom condo's rent.

How much is the rent for all three condos? Define your variables then write and solve a

system of equations.

Answers

Answer 1

Answer:

1 bedroom = $280

2 bedroom = $400

3 bedroom = $560

Step-by-step explanation:

Given that :

Total rent received = 1240

Rent amount of 3 bedroom = 2 times rent of 1 bedroom

Let 1 bedroom = x

2 bedroom = y

3 bedroom = 2x

x + y + 2x = 1240

3x + y = 1240 ---(1)

Repair cost :

10% of x = 0.1x

20% of y = 0.2y

30% of 2x = 0.6x

0.1x + 0.2y + 0.6x = 276

0.7x + 0.2y = 276 - - - (2)

From (1)

y = 1240 - 3x

0.7x + 0.2(1240 - 3x) = 276

0.7x + 248 - 0.6x = 276

0.1x + 248 = 276

0.1x = 28

x = $280

1 bedroom = $280

3 bedroom = $280 * 2 = $560

2 bedroom = $1240 - $840 = $400

At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?

Answers

Answer:

52 young calves

Step-by-step explanation:

At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?

The ration is given as:

adult milking cows to young calves

= 9 : 2

= 234 : x

= 9/2 = 234/x

x = Number of young calves

Cross Multiply

9 × x = 2 × 234

= x = 2 × 234/9

x = 468/9

x = 52

Hence, the number of young calves on the farm is 52.

By coincidence, Kimberly's Paint Supplies sold equal quantities of two paint colors yesterday: yellow and blue. All yellow paint comes in 9-liter containers while blue paint is sold in 12-liter containers. What is the smallest amount of each paint color the store must have sold?

Answers

Answer:

36 liters

Step-by-step explanation:

We solve this question using the least common multiple method

Find and list multiples of the liter the blue paint comes in the liters the yellow paint comes in. We find the first common multiple is found. This is the least common multiple.

Multiples of 9:

9, 18, 27, 36, 45, 54

Multiples of 12:

12, 24, 36, 48, 60

Therefore,

LCM(9, 12) = 36

Hence, the smallest amount of each paint color the store must have sold is 36 liters

Answers

Answer:

V/3k = t

Step-by-step explanation:

Isolate the variable (t)

V = 3k/t

We have to get rid of 3 and k to isolate t

Since 3 and k are part of a fraction we can multiply it by their reciprocal

V = 3k/t × 1/3k

What we do to one side, we must do to the other

V × 1/3k = 3k/t × 1/3k

The reciprocals equals 1

V × 1/3k = t × 1

Any number or variable multiplied by 1 equals itself (applies to both sides of the equation)

V/3k = t

The first equation of the system is multiplied by 2.By what number would you multiply the second equation to eliminate the x variable by adding? 6x - 5y = 21 4x + 7y = 15

Answers

Answer:

We have to multiply 4 with 3 to make it equal to 12.

Step-by-step explanation:

Given the two equations:

[tex]6x - 5y = 21\\ 4x + 7y = 15[/tex]

In elimination method for solving two linear equations in two variables, one variable is eliminated by making the coefficients of the variable equal to each other and then the equations are subtracted from each other so that only one variable remains.

Here, we have to eliminate [tex]x[/tex].

The coefficients are 6 and 4.

The least common multiple of 6 and 4 is 12.

So, we multiply 6 by 2 to make it equal to 12.

and we have to multiply 4 with 3 to make it equal to 12.

And then the two equation have to be subtracted from each other.

Find the value of X for the given pentagon?

Answers

Answer:

x = 44°

Step-by-step explanation:

The sum of the exterior angles of any polygon my be 360°, so just add all the angles up, and subtract this from 360°.

Given a pentagon with exterior angles: 102°, 47°, 34°, and 133° with the missing angle x°.

To find the missing angle, first write an equation representing the given rule:

102° + 47° + 34° + 133° + x° = 360°

(316°) + x° = 360°

316° + x° - 316° = 360° - 316°

x° = 44°.

This way, because the rule must be true, the missing angle with this value will satisfy this:

102° + 47° + 34° + 133° + 44° = 360°

For this topic, here are some general angle rules for polygons:

n is the number of sides180° (n – 2) = sum of interior angles of any polygon.180° (n – 2) / n = each interior angle of a regular polygon [all sides and or angles the same measure / congruent].360° = sum of exterior angles of any polygon.360° / n = each exterior angle of a regular polygon. [all sides and or angles the same measure / congruent].

1.51

Step-by-step explanation:

[tex]y[/tex] = Cost in dollars of vegetables

[tex]x[/tex] = Number of pounds of vegetables

[tex]y\propto x[/tex]
