__________

$\:$

a² = c² - b²

a² = 9² - (√65)²

a² = 81 - 65

a² = 16

a = √16

a = 4

Use Pythagorean theorem

$\\ \sf\longmapsto P^2=9^2-(√65)^2$

$\\ \sf\longmapsto P^2=81-65$

$\\ \sf\longmapsto P^2=16$

$\\ \sf\longmapsto P=4$

Seed costs for a farmer are $40 per acre for corn and $32 per acre for soybeans. How many acres of each crop should the farmer p

Natalija [7]

Answer:

$40x+32y\leq 5,000\\x\geq 0, y\geq 0$

Step-by-step explanation:

Let the number of acre of corn planted =x

Let the number of acre of soybeans planted =y

Seed costs for a farmer are $40 per acre for corn and $32 per acre for soybeans.

Seed Cost for x acre of corn = $40x
Seed Cost for y acre of soybeans = $32y

The farmer wants to spend no more than $5,000 on seed.

Therefore the linear inequality is:

$40x+32y\leq 5,000\\x\geq 0, y\geq 0$

Next, we graph the inequality

$When$ x=0, y\leq156.25\\When$ y=0, x \leq 125$

The graph is attached below.

Maru [420]

Answer:

A. 450

Step-by-step explanation:

180 is 40% of the original

450*0.4=180

298*0.4=119.2

240*0.4=96

72*0.4=28.8

so A. 450 is correct

The first term in a sequence is 3. the term to term rule is add 5. is 97 at term in the sequence? give a reason why.

Harlamova29_29 [7]

Answer: No it’s not.

Step-by-step explanation: So if to find the next number, you add five, then all of the numbers in the sequence will either end with 8 or 3. (5+3 or 0+3). Therefore 97 is not a term in the sequence.
