There are 75 new houses being built in a neighborhood. Last month, 2/5 of them were sold. This month,1/3 of the remaining houses were sold. How many houses are left to be sold? ​

Answers

You start with 75 houses

2/5 were sold, which mean 3/5 remain
3/5 of 75 is 45

Then, 1/3 of the REMAINING (45) houses were sold. Since 1/3 were sold, 2/3 remain of 45.
2/3 of 45 is 30

30 houses are left to be sold

a) alternate interior angles

b) vertical angles

c) corresponding angles

d) linear pair

Step-by-step explanation:

Alternate interior angles:

formed when a transversal intersects two lines on the same plane located on the inside/interior side of the parallel lines, but they're on the opposite sides  these angles are congruent Example: angles D and E

Vertical angles:

pair of opposite angles formed by lines that intersect these angles are congruentExample: angles E and H

Corresponding angles:

angles that have the same relative position, formed by a transversal intersecting two parallel lines these angles are congruent  Example: angles A and E

Linear pair:

pair of adjacent angles formed by two intersecting linesangles have measures that add up to 180 degreesExample: angles C and D

Put the following equation of a line into slope-intercept form, simplify all fractions 8x + 20y = -120

Answers

Hello there! :)

8x+20y=-120

We want to put this equation into slope-intercept form (y=mx+b)

First, let's move 8x to the right side:

20y=-120-8x

Now, we divide both sides by 20 to isolate y:

y=-8/20-6

Simplify the fraction:

y=-2/5-6

Hence, that's our equation. Hope it helps you! (:

Peter watches 345 more American movies than Chinese movies. the ratio of Chinese movies to American movies is 4:7 . how many American movies does Peter watch?​

Answers

Peter watches 805 American movies and 460 Chinese movies.

Let x represent the number of American movies and y represent the number of Chinese movies and let z represent the total number of movies.

Since he watches 345 more American movies than Chinese movies. Hence:

x = y + 345

x - y = 345    (1)

Also:

x + y = z

x + y - z = 0  (2)

The ratio of Chinese movies to American movies is 4:7. Hence:

(4/11)z = y

-y + (4/11)z = 0   (3)

Solving equations 1, 2, and 3, simultaneously gives:

x = 805, y = 460 and z = 1265

Hence, Peter watches 805 American movies and 460 Chinese movies.

Sofia planted a maple tree sapling that was 5.5 inches tall. The tree grew 10 inches each year. Write an equation that shows how the sapling's height in inches, y, depends on the number of years since it was planted, X. Y =​

Answers

Answer:

y= (10*x)+5.5

Step-by-step explanation:

B)

Answer:

y = 10x + 5.5

Step-by-step explanation:

We can write our equation in slope-intercept form, which looks like y = mx + b. "m" is our growth rate, and "b" is our y-intercept, or starting value.

So, let's fill in "m" first. What is our growth rate? Well, 10 inches per year. So, we can replace "m" with 10: y = 10x + b. But we have to figure out which number to replace "b" with. In this scenario, Sofia planted the maple tree when it was already 5.5 inches tall. So, when it grows 10 inches per year, the inches are being added to that original value. 5.5 is our starting value: y = 10x + 5.5. And that's our final equation.

Hopefully that's helpful! :)

4. On Monday, a department store sold 30 white and blue sweaters in total. If a white sweater is 398 baht, and a blue sweater is 420 baht, the total sales are 12,424 baht. How many sweaters in each color did this department store sell?

Answers

The number of white sweaters will be 8 while the number of blue sweaters will be 22.

Let white sweaters be represented by w.Let blue sweaters be represented by b

Therefore, the equation to solve the question will be:

b + w = 30 .....i

420b + 398w = 12424 .... ii

From equation i, b = 30 - w

Since 420b + 398w = 12424

420(30 - w) + 398w = 12424

12600 - 420w + 398w = 12424

Collect like terms

- 420w + 398w = 12424 - 12600

-22w = - 176

w = 176/22 = 8

Since b + w = 308

b = 30 - 8 = 22

Therefore, there are 8 white and 22 blue sweaters.

what percentage of this grid is shaded

how many more squares need to be shaded so that 60% of the grid is shaded?

Answers

Answer:

44%, and 4

Step-by-step explanation:

The grid has 5 rows and 5 columns so we have 5*5 = 25 squares.

25 squares represent 100 %  of the grid

a) In the grid 11 of the 25 total squares are blue, so if

25 squares are 100%

11 squares will be x%

x= (11* 100) / 25 = 1100/ 25 = 44 %

b) we find the number of squares that gives us 60 %

25 squares are 100%

x squares will be 60%

x= (60*25)/ 100 = 15

The question is " How many more squares " so we have to compare with the 11 given ones in part a)

15 -11 = 4

4 more squares will give 60 %  blue grid.  

The answer should be 25 squares is 100 percent
