Answer:

Parallel lines are lines that never touch each other

Step-by-step explanation:

they are straight and go on forever without intersecting (crossing)

Answer:

parallel lines are always the same distance apart from each other at all times, they never come in contact with one another

Step-by-step explanation:

They never intersect. It is difficult to explain, but you can look at examples on the internet. Hope this helps, have a good day, and good luck with your summer homework and good luck in 6th grade :)

Step-by-step explanation:

because I am not sure what to do with my life

Answer:

1/2

Answer:

  (d)  x = -3/4; y = -3 1/2

Step-by-step explanation:

You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.

The idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.

In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.

horizontal coordinate

The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.

  x = -3/4

vertical coordinate

The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.

  y = -3 1/2

Answer:

C (√34)

Step-by-step explanation:

Pythagoras' theorem states that: a² + b² = c², where c is the hypotenuse and what we are trying to figure out.

So, 3² + 5² = c²

9 + 25 = 34 = c²

c = √34

:)

Answer:

C (√34)

Step-by-step explanation:

Answer:

A) (x+10)(x+4) = ?

B) (x+10)(x+4) = 112, solve for x

Step-by-step explanation: you multiply the two equations to get the area.

Answer:

a)[tex](x^{2} +14x+40)ft^{2}[/tex]

b)14ft, 8ft

Step-by-step explanation:

a) Area of Rectangle = Length x Breadth

= [tex](x+10)(x+4)\\=x^{2} +4x+10x+40\\=(x^{2} +14x+40) ft^{2}[/tex]

b) Given Area of rectangle = [tex]112ft^{2}[/tex]

[tex]x^{2} +14x+40=112\\x^{2} +14x-72=0 (Quadratic Equation)\\\\[/tex]

Quadratic Equations: [tex]ax^{2} +bx+c = 0\\[/tex]

In this case, a = 1, b = 14, c = -72

[tex]\frac{-b+/-\sqrt{b^{2}-4ac } }{2a} \\= \frac{-14+/-\sqrt{14^{2} 4(1)(-72)} }{2(1)} \\= 4 or - 18 (reject)[/tex]

We reject negative values.

so x = 4,

The length of table = (x+10) ft = 4+10 = 14ft

The breadth of the table = (x+4) ft = 4 + 4 = 8ft

Answer:

I believe it is A

Answer:

Cold length 7 days or longer with medicine taken = 0.24

Cold length less than 7 days with medicine taken = 0.76

Cold length 7 days or longer without medicine taken = 0.69

Cold length less than 7 days without medicine taken = 0.31

Answer: C

Step-by-step explanation:

Step 1: Find the unit rate (tomatoes  per  bowl)

Last time, the ratio was 9:12, or 9 tomatoes for 12 bowls of soup. To finndd the unit ratet, dividde the ffirst given unnit by the 2nd. In this case, tomatoes is the first unit, and bowls is the second. So the unit rate is:

9÷12= 0.75, or 3/4 of a tomato  per bowl of soup.

Now, the  ratio is 6:8, or 6 tomatoes for 8 bowls of soup. The unit rate is

6÷8= 0.75, or 3/4of a tomato per bowl of soup.

Step 2: Compare

As you can see, the number of tomatoes per bowl of soup hasn't changed at all. So the answer is C.

Hope this helps :)

Answer:

Todays’s soup will taste the same.

Step-by-step explanation:

9 tomatoes for every 12 cups of soup- ratio= 9/12=3/4

6 tomatoes for every 8 cups of soup- ratio=6/8=3/4

They both end in the same ratio, which is 3/4.

Answer:

There are 23 cats for every 36 dogs at the city pound

Step-by-step explanation:

This means that for every group of 92 cats at the city compound there is a group of 144 dogs. So it also means that for every group of 23 cats there is a group of 36 dogs.

92 to 144 or 92/144 = 23/26  or 23 to 36

Answer:

8:12

around every 8(7.6)cats there will be 12 dogs

Answer:

D. 11n + 12

Step-by-step explanation:

You can simplify the 4n + 7n to be 11n by adding them together.

This means the answer is 11n + 12.

Answer:

x = 7

or

7 + 10 + 4 = 7 + 10 + 4

Step-by-step explanation:

( ? + 10 ) + 4 = 7 + ( 10 + 4 )

x + 10 + 4 = 7 + 10 + 4  (the answer is just 7)

x + 14 = 21

x = 21 - 14

x = 7

Answer:

I think C

Step-by-step explanation:

A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by  the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.

Answer:

  D.  8/7

Step-by-step explanation:

A probability value is always in the interval [0, 1], between 0 (can't happen) and 1 (certain to happen).

A value of 8/7 will not be a probability. Statement D does not correctly use probability.
