Point B is collinear with A and C and partitions AC in a 3:4 ratio. B is located at (4,1) and C is located at (12,5). Find the c

GrogVix [38]

Answer:

$A(-\frac{20}{3} ,-\frac{13}{3})$

Step-by-step explanation:

Point B partitions AC in a 3:4 ratio.

B is located at (4,1) and C is located at (12,5).

Let $(x_1,y_1)$ be the coordinates of A.

Then $(\frac{mx_1+nx_2}{m+n}, \frac{my_1+ny_2}{m+n})=(4,1)$

But m:n=3:4 implies m=3 and n=4 and $(x_2=12,y_2=5)$

$(\frac{3x_1+4*12}{3+4}, \frac{3y_1+4*5}{3+4})=(4,1)$

$(\frac{3x_1+48}{7}, \frac{3y_1+20}{7})=(4,1)$

$\frac{3x_1+48}{7}=4, \frac{3y_1+20}{7}=1$

$3x_1+48=28, 3y_1+20=7$

$3x_1=-20, 3y_1=-13$

$x_1=-\frac{20}{3} , y_1=-\frac{13}{3}$

In a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy

forsale [732]

Answer:

So, the way a ratio works is "for every 1 of this, we have 4 of this" for example. (the ratio I just described would be 1:4.)

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.

So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.

So:

240 ÷ 3 = 80

If your ratio is 9:3, then 80 is your answer.

Hope this helps and have a nice day!

Select the correct answer. Simplify the expression. (see the screenshot)

Sliva [168]

Answer:

Option D

Step-by-step explanation:

Given expression has been given as,

$\sqrt[5]{224x^{11}y^8}$

$\sqrt[5]{224x^{11}y^8}=\sqrt[5]{2\times 2\times 2\times 2\times 2\times 7(x^{11})(y^8)}$

$=\sqrt[5]{(2^5)\times (7)(x^{10}\times x)(y^5\times y^3)}$

$=2^{\frac{5}{5}}\times 7^{\frac{1}{5}}\times x^{\frac{10}{5}}\times x^{\frac{1}{5}}\times y^{\frac{5}{5} }\times y^{\frac{3}{5} }$

$=2\times 7^{\frac{1}{5}}\times x^2\times y\times x^{\frac{1}{5} }\times y^{\frac{3}{5} }$

$=2x^2y\sqrt[5]{7xy^3}$

Option D will be the answer.

Answer:

Rectangle

Step-by-step explanation:

Note the definition of a rectangle. All angles must be 90°, and opposite sides are parallel and congruent.

It says that Andre "drew a quadrilateral with four right angles and two pairs of congruent sides.", making rectangle a candidate as an answer.
