It's completely correct to use the ' / ' sign for division.
Every fraction means division. It means

(the top number) divided by (the bottom number) .

These are easy to do on a calculator, and by now you should
also know how to do them with a pencil.

1). 5,320 / 61 = 87.213... (plus more decimal places)

2). 776 / 28 = 27.714... (plus more decimal places)

3). 1,624 / 23 = 70.608... (plus more decimal places)

The equation for line t can be written as y = 4x - 8. Line u, which is perpendicular to line t,

xeze [42]

Here, we are required to determine the equation of the line u which is perpendicular to the line t and passes through the point (8,8).

The equation of the line u is;. y = (-x/4) + 10.

First, the product of the slope of 2 perpendicular lines is negative 1 i.e -1.

M1 × M2 = -1

From observation, the slope of line t given by y = 4x - 8 is equal to 4.

Therefore, since M1 = 4,
Then, M2 = -1/4

To get the equation of a line,

Slope, M2 = (y - y1)/(x - x1)

where M2 = -1/4 , y1 = 8 and x1 = 8.

Therefore, -1/4 = (y - 8)/(x - 8).

Therefore, -x + 8 = 4y -32

Therefore, 4y = -x + 40.

Ultimately, the equation of the line u is ;

y = (-x/4) + 10.

If angela swims 1,700 meters in 40 minutes what is her unit rate

LuckyWell [14K]

1700m = 40 mins
60 mins = 1 hour
60 mins - 40 mins = 20 mins (Half of more)
1700 / 2 = 850
1700 + 850 = 2550 meter/hour

So far, 37 miles of a new highway have been completed. This is one mile less than two thirds of the entire length. How long will

blagie [28]

37 = 2/3x - 1
37 + 1 = 2/3x
38 = 2/3x
38 / (2/3) = x
38 * 3/2 = x
114/2 = x
57 = x <=== when complete, the highway will be 57 miles

Segment BD is an altitude of triangle ABC. Find the area of the triangle.

Sever21 [200]

Answer: The correct option is A, i.e., 7.5.

Explanation:

It is given that ABC is a triangle and BD is an altitude.

Since BD is an altitude, therefore the height of the triangle is BD and the base of the triangle is AC.

The distance formula to find the distance between two points is,

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

First, we find BD, where B(-1,4) and D(2,4).

$BD=\sqrt{(2+1)^2+(4-4)^2}=\sqrt{9} =3$

So, the height of the triangle is 3.

Now, we find the value of AC, where A(2,1) and C(2,6).

$AC=\sqrt{(6-1)^2+(2-2)^2}=\sqrt{25} =5$

So, the base of the triangle is 5.

The formula to find the area of a triangle is,

$A=\frac{1}{2}\times {\text{base}}\times {\text{height}}$

$A=\frac{1}{2}\times 5\times 3=\frac{15}{2}=7.5$

Therefore, the area of the triangle is 7.5 unit square and the correct option is A.
