This becomes: A = 1/2 * (3) * (8 ) = 1/2 * 24 = 12
So the area is 12.
Hope this helps!

1 1/4 is too 1/4 as 2 is to?

loris [4]

Answer: 1/4:1 1/4 = 2:b

↓

1/4 / 5/4 = 2/b

4/4 * 5 = 2/b

1/5 = 2/b

b/5 = 2

b = 2 * 5

b = 10

A point M on a segment with endpoints X(1, −2) and Y(10, 3) partitions the segment in a 4:1 ratio. Find M. You must show all wor

inna [77]

Answer:

$\displaystyle \: M = \left( 8\frac{1}{5},2\right)$

Step-by-step explanation:

we want to figure out the point "M" which is on a segment with endpoints X(1,-2) and Y(10,3) partitions the segment in a 4:1 ratio.

to find so, we can consider section formula . we know that Section formula is used to find the ratio in which a line segment is divided by a point internally or externally the ratio is written as m:n

however in this case the following formula can be used used:

$\displaystyle \left( \frac{m x_{2} +n x_{1}}{m + n} , \frac{m y_{2} + n y_{1}}{m +n}\right)$

step-1: assign variables

assign variables:

$(x_{1},y_{1}) = (1, - 2)$
$(x_{2},y_{2}) = (10, 3)$
$m : n = 4 :1$

step-2: substitute

$\displaystyle \left( \frac{(4) (10) +(1)(1) }{4 +1} , \frac{(4)(3)+ (1) ( - 2)}{4 +1}\right)$

simplify multiplication:

$\displaystyle \left( \frac{40 + 1 }{4 + 1} , \frac{12+ ( - 2)}{4 + 1}\right)$

simplify addition:

$\displaystyle \left( \frac{41 }{5} , \frac{10}{5}\right)$

simplify division:

$\displaystyle \left( 8\frac{1}{5},2\right)$

hence,

$\displaystyle \: M = \left( 8\frac{1}{5},2\right)$

Hey can you please help me posted picture of question :)

The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.

(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab

x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.

Thus the answer to this question is option C

Karl wants to rent a bike for at most $55. He can rent a bike for $7 per hour plus a $9.50 flat fee. Any portion of an hour is c

Anvisha [2.4K]

6.5 because you instantly take $9.50 away from $55. After you get that answer, you will have 45.5. Then divide 45.5 by 7 which will give you 6 and a half hours.
