we are given with an isosceles triangle with two congruent sides equal to 70 inches and an angle of 36 degrees in between the sides. We are asked for the area of the triangle. The formula is A = 0.5 *  ab sin theta where  a and b are the sides. The area is equal to 1440. 07 in2.

What are the coordinates of point A? (8, –6) (–6, 8) (6,-8) (-8, –6)
Jlenok [28]

The coordinates of the point A is (7, -5)

<h3>What are the coordinates of the image?</h3>

Now, we are given 4 coordinates which are;

(8, –6)

(–6, 8)

(–5, 7)

(7, –5)

Now, from the image attached, we can see that at point A, the coordinate can be traced to be (7, -5)

Thus, we conclude that the coordinates of the point A is (7, -5)

The correct question is;

What are the coordinates of point A?

(8, –6)

(–6, 8)

(–5, 7)

(7, –5)

Working together, it takes two different sized hoses 35 minutes to fill a small swimming pool. If it takes 60 minutes for the la
almond37 [142]

L = rate of the large hose

S = rate of the small hose

we know the sum of their rates deliver the swimming pool filled up in 35 minutes, thus L + S = 35.

now, the large hose can do it in 60 minutes, that means that in 1 minute, the large hose has only done 1/60 th of the work.

the small hose can do the whole thing in S minutes, that means in 1 minute it has only done 1/S th of the whole work.

and since both of them working together can do it in 35 minutes, then in 1 minute they both have done 1/35 th of the whole job.

\bf \stackrel{\textit{large's rate in 1 minute}}{\cfrac{1}{L}}+\stackrel{\textit{small's rate in 1 minute}}{\cfrac{1}{S}}=\stackrel{\textit{done in 1 minute}}{\cfrac{1}{35}} \\\\\\ \cfrac{1}{60}+\cfrac{1}{S}=\cfrac{1}{35}\implies \cfrac{S+60}{60S}=\cfrac{1}{35}\implies 35S+2100=60S\implies 2100=25S \\\\\\ \cfrac{2100}{25}=S\implies 84=S

I need help. how do i completely factor 6x^2+7x+2 with an explanation?
AnnZ [28]

Answer:

(2x + 1)(3x + 2)

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 6 × 2 = 12 and sum = 7

The factors are + 3 and + 4

Use these factors to split the x- term

= 6x² + 3x + 4x + 2 ( factor the first/second and third/fourth terms )

= 3x(2x + 1) + 2(2x + 1) ← factor out (2x + 1) from each term

= (2x + 1)(3x + 2) ← in factored form

Juanita is making necklaces to give as presents. She plans to put 15 beads on each necklace. Beads are sold in packages of 20. W
erastovalidia [21]
Hi there!

It should be 4 packages, with some mental math.

4 * 20 = 80

4 * 15 = 60

Remember we still have 20 beads left over now. Add it to 60 and bam! You're done!
