The slope of a line is – 3, and a point on the line is (4, -1).
What is the equation of the line expressed in slope-intercept form?

Answer:

Step-by-step explanation:

the scale factor is 0.8:20

since the line is 239 miles long, divide by 20

239/20 = 11.95

multiply by 0.8

11.95 x 0.8 = 9.56

Answer:

x=4 or -4

y=5

Step-by-step explanation:

Answer:

48 ft

Step-by-step explanation:

this is because the perimeter of the room is its sides so first you 9x2=18

then 14x 2= 28 and then 28 + 18 and you get 48 ft

Answer:

ur correct it's A. trust me u look up all the definitions to the other than A. they gonna be wrong already looked em all up

Answer:

a = -30

d = -32 - (-30) = -2

n = 96

So, using A.P. formula-

Tn = a + (n-1) d

T96 = -30 + (96-1) -2

T96 = -30 + (95) -2

T96 = -30 - 190

T96 = -220

Answer:

0.006

Step-by-step explanation:

Answer:

Explanation:

611 or 6÷11=0.545454545....

The hundredth position is two positions to the right of the decimal point. For this problem it is the 4:

0.545454545....

To round to the nearest hundredth you must look at the digit in the position immediately to the right of the digit in the hundredth place, which is the 5 in the thousandth place:

0.545454545....

If the digit to the right is greater than or equal to 5 you add 1 to the digit you are rounding to and make everything to the right 0.

If the digit to the right is less than 5 you add keep the digit you are rounding to the same and make everything to the right 0.

In this problem the digit to the right is a 5 so we add 1 to the digit we are rounding to and make everything to the right 0.

0.545454545....=0.550000000....=0.55

Answer:  15 units .

__________________________________________________

In this case, a square, the two sides of the square (forming a right triangle) are equal), and the "diagonal" forming is the hypotenuse of the right triangle.

In these cases, the measurements of the angles of the right triangle are "45, 45, 90" ; and the measurements of the sides are:  "a, a, a√2" ; in which "a√2" is the hypotenuse.

We are given:  "15√2" is the hypotenuse" ; and we are given that this is a right triangle of a square with a diagonal length (i.e. "hypotenuse" of "15√2" ; so the measure of the side of the "square" (and other two sides of the triangle formed) is:  15 units.   (i.e.,  15, 15, 15√2 ).

  (b)  ... because of the AA similarity postulate

Step-by-step explanation:

The problem statement tells you that you are showing ∠F≅∠C. We already know that ∠A≅∠D, because they are both marked as right angles. Thus the given mapping results in two of the three angles being shown congruent, allowing you to conclude ...

Answer:

[tex]\frac{3}{2}[/tex] square feet

Step-by-step explanation:

The dimensions of the photo is 4/5 by 1 7/8 of a foot.

But,

1 7/8 = [tex]\frac{15}{8}[/tex] feet

So that,

length of the photo = [tex]\frac{15}{8}[/tex] feet

width of the photo = [tex]\frac{4}{5}[/tex] feet

The area of the photo = length x width

                                     = [tex]\frac{15}{8}[/tex] x [tex]\frac{4}{5}[/tex]

                                     = [tex]\frac{60}{40}[/tex]

                                     = [tex]\frac{3}{2}[/tex]

Area of the painted photo is [tex]\frac{3}{2}[/tex] square feet.

Answer:

D.2.58

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.

The answer is given by option D.

Answer:

A

Step-by-step explanation:

Part A, A. Kari, because the mean and median of her scores is, 84.5.

Part B, Jocely will see a greater increase overall as her previous average is less.

The three main methods for identifying the average value of a set of integers are mean, median, and mode.

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.

The middle value in a list that is arranged from smallest to greatest is called the median.

The value that appears the most frequently on the list is the mode.

From the given information, The average score of Jocelyn is,

= (86 + 87 + 95 + 72 + 78 + 80)/6.

= 83.

And Similarly, The average score Kari is,

= (88 + 78 + 93 + 81 + 75 + 91)/6.

= 84.5.

Therefore, Kari scores better overall.

If they both get 90% on their next math quiz Jocely will see a greater increase overall as her previous average is less.

Multiplication

Step-by-step explanation:

To convert from a larger unit to a smaller unit, we multiply. This is because the number will become greater since the unit is smaller.

Example:

1 m ⇒ ×100 ⇒ 100 cm

We use division when converting from a smaller unit to a larger unit since the number will become smaller as the unit becomes greater.

Example:

100 cm ⇒ ÷100 ⇒ 1 m

Answer:

6.24

Step-by-step explanation:

To find the area of the triangle, it is base times height divided by 2 after you multiply. Height is 90 degrees from base so remember that.

In this example, do (2.6 x 4.8)/2

Equals 6.24
