Given: PQ ⊥ QR , PR=20, SR=11, QS=5 Find: The value of PS.

Neporo4naja [7]

1. PQR and is a right triangle, so you can calculate the measure of PQ by applying the Pythagorean Theorem. PR is the hypotenuse and QR and PQ are the legs:

$PR^{2}=PQ^{2}+QR^{2}\\ PQ=\sqrt{PR^{2}-QR^{2}}\\ PQ=\sqrt{20^{2}-16^{2}} \\ PQ=12$

2. PQS and is a right triangle too, so you can calculate the measure of PS by applying the Pythagorean Theorem as above. PS is the hypotenuse and PQ and QS are the legs:

$PS=\sqrt{PQ^{2}+QS^{2}}=13$

Therefore, the answer is: The value of PS is 13.

Henrietta is planting a new flower garden she must have yellow and red rose bushes let X represent the number of yellow rose bus

salantis [7]

Answer:

$x \geq 4y$

$7.50x+4.75y\leq 125$

$x > 0$

$y > 0$

Step-by-step explanation:

Let

x -----> the number of yellow rose bushes

y -----> the number of red rose bushes

we know that

At least means "greater than or equal to"

$x \geq 4y$ ----> inequality A

$7.50x+4.75y\leq 125$ -----> inequality B

additionally

The number of roses cannot be a negative number

so

$x > 0$ ----> inequality C

$y > 0$ ----> inequality D

therefore

The restraints are

$x \geq 4y$

$7.50x+4.75y\leq 125$

$x > 0$

$y > 0$

When do you get an answer to a system of linear equations that has one solution, no solution and infinitely many solutions?

meriva

Answer:

Step-by-step explanation:

One solution: when two lines intersect in exactly one point.

Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.

No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.
