What is the ratio AC: CB?​

Answers

Answer:

D. 1 : 2

Step-by-step explanation:

Given:

A(-6, -2),

B(6, 7),

C(-2, 1)

Required:

Ratio of AC : CB

SOLUTION:

Find AC:

[tex] AC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] A(-6, -2) = (x_1, y_1) [/tex]

[tex] C(-2, 1) = (x_2, y_2) [/tex]

[tex] AC = \sqrt{(-2 -(-6))^2 + (1 -(-2))^2} [/tex]

[tex] AC = \sqrt{(4)^2 + (3)^2} [/tex]

[tex] AC = \sqrt{16 + 9} = \sqrt{25} [/tex]

[tex] AC = 5 [/tex]

Find CB:

[tex] CB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] C(-2, 1) = (x_1, y_1) [/tex]

[tex] B(6, 7) = (x_2, y_2) [/tex]

[tex] CB = \sqrt{(6 -(-2))^2 + (7 - 1)^2} [/tex]

[tex] CB = \sqrt{(8)^2 + (6)^2} [/tex]

[tex] CB = \sqrt{64 + 36} = \sqrt{100} [/tex]

[tex] CB = 10 [/tex]

Find AC : CB

AC : CB = 5 : 10 = 1 : 2

A cyclist rode at a constant speed of 21mph for 3 hours. Then she decreased her rate of speed to 17 mph for 4 hours. How far fid they cyclist ride in 7 hour

Answers

Answer: 131 miles; 21 x 3 = 63 + 17 x 4 = 68. 63 + 68 = 131 miles

Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.

What is the speed?

The magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here given that,

A cyclist rode at a constant speed of [tex]21[/tex]mph for [tex]3[/tex] hours. Then she decreased her rate of speed to [tex]17[/tex] mph for [tex]4[/tex] hours.

[tex]21[/tex] x [tex]3[/tex]  [tex]=63 + 17 (4)[/tex]

[tex]= 131[/tex] miles

Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.

How many quarts of water must be added to 7 qts of a 19% saline solution to obtain a 5% saline solution?

Answers

Answer: quantity of water added = 19.6 quarts

Step-by-step explanation:

Let x= quantity of water added

Then, Quantity of saline in 7 quarts solution  = 19% of 7 = 0.19 (7)=1.33 quarts [to remove % divide number by 100]

When x quarts water is added , the quantity of solution becomes = x+7

Quantity of saline in it= 5% of (x+7)= 0.05(x+7)

Now, quantity of saline remains same, so

[tex]1.33= 0.05(x+7)\\\\\Rightarrow\ 1.33x=0.05x+0.35\\\\\Rightarrow\ 1.33-0.35=0.05x\\\\\Rightarrow\ x=\dfrac{0.98}{0.05}=19.6[/tex]

Hence,  quantity of water added = 19.6 quarts
