6. Find QR, if area and altitude PS of ∆PQR are given<br> ar(∆PQR) = 180 cm2, PS = 15​
Slav-nsk [51]

Given:

Area and altitude PS of ∆PQR are ar(∆PQR) = 180cm² and PS = 15​.

To find:

The measure of side QR.

Solution:

According to the given information, PS is an altitude of ∆PQR. It means QR is the base of ∆PQR.

We know that, the area of a triangle is

Area=\dfrac{1}{2}\times Base\times Height

ar(\Delta PQR)=\dfrac{1}{2}\times QR\times PS

Substituting the given values, we get

180=\dfrac{1}{2}\times QR\times 15

180\times 2=QR\times 15

360=QR\times 15

Divide both sides by 15.

\dfrac{360}{15}=QR

24=QR

Therefore, the measure of side QR is 24 cm.

Solve each system of equation by substitution y=-x+5 x+2y=2​
Likurg_2 [28]

Answer:

x = 8

y = -3

Step-by-step explanation:

Given :

y = -x + 5 ...................... equation 1

x + 2y = 2 ........................ equation 2

solving the system of linear equation by substitution method , substitute equation 1 into equation 2 , that is

x + 2(-x+5) = 2

x - 2x + 10 = 2

-x + 10 = 2

collect the like terms

10 - 2 = x

therefore :

x = 8

substitute x = 8 into equation 1 to find the value of y , that is

y = -8 + 5

y = -3

Therefore :

x = 8

y = -3

An opaque bag contains 5 green marbles 3 blue marbles and 2 red marbles. What is the probability of randomly picking out a marbl
anastassius [24]

Answer= .2 probability

Explanation: Since there is a total of 10 marbles, and 2 are red, you would divide the red marbles (2) out of the total marbles (10) which would get u .2. Since it’s asking for probability, we would keep .2 a decimal.
