Find the distance between the points with the given coordinates (-4, 9) and (1, -3).

Dmitriy789 [7]

Answer: 13

Step-by-step explanation:

The formula for finding distance between two points is given by :

D = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$x_{1}$ = -4

$x_{2}$ = 1

$y_{1}$ = 9

$y_{2}$ = -3

Substituting the values into the formula , we have :

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

D = $\sqrt{(5)^{2}+(-12)^{2}}$

D = $\sqrt{25+144}$

D = $\sqrt{169}$

D = 13

Therefore : the distance between the points is 13

What's the answer for this problem number 6 and how did you get your answer?

lorasvet [3.4K]

$\frac{7}{b + 5} = \frac{10}{5} \\$

$\frac{7}{b + 5} = 2 \\$

Multiply the sides of the equation by ( b + 5 ) :

$7 =2 \times (b + 5)$

$7 = 2b + 10$

Subtract the sides of the equation minus 10 :

$7 - 10 = 2b$

$- 3 = 2b$

Divided the sides of the equation by 2 :

$b = - \frac{3}{2} \\$

I attempted this already, What is the area of the trapezoid?

larisa [96]

Answer:

40.5 cm

Step-by-step explanation:

So think about it what is the Formula for a Trapezoid? Well it's h(b1+b2)/2! So we use this formula and place the numbers in there! When you're done you should have this: 6(9+4.5)/2. Now we will do <u>PEMDAS</u> (parenthesis, exponents, multiplication, division, addition, subtraction). from left to right. So we first do 9+4.5. That equals 13.5. Then we times that by 6, which is 81. Then we finally divide it by 2. Then there's your answer! :D

If you have 5 tenths of a dollar, how much money do you have

horrorfan [7]

A tenth is 1/10.
5 tenths is 5/10.

5/10 is a fraction that can be made simpler, by dividing by 5, so that the fraction becomes 1/2.

1/2 is a half, so if you have a half a dollar, you have 50 cents.

Hope I helped. :)

A restaurant bill comes to $28.35 find the total coast if the tax is 6.25% and 20% tip is left on the amount before tax

luda_lava [24]

Answer:

The total cost of the bill = $36.146

Step-by-step explanation:

Here, the total amount of the bill = $28.35

Now, the amount of tip = 20%

So, calculating 20% on the bill amount, we get

$\frac{20}{100} \times 28.35 = 5.67$

or, the amount of 20% tip = $5.67

So, the total bill amount after 20% tip = Bill Amount + Tip

= $28.35 + $5.67 = $34.02

Now, the tax is calculated on the amount of bill $34.02.

$\frac{6.25}{100} \times 34.02 = 2.126$

or, the amount of tax on the bill = $2.126

So, the total bill amount after 6.25% tax = Bill Amount + Tax

= $34.02 + $2.126 = $36.146

Hence, the total cost of the bill = $36.146.
