The surface area of the given right angled triangular prism is 60 square centimeters (cm^{2}).            

Step-by-step explanation:

The given is,

              Right angled triangular prism

Step:1

           Surface area of triangular prism,

                  Surface area of prism = Sum of area of each sides.........(1)

Step:2

          Area of Triangular face,

                                                     = \frac{1}{2}(base)(height)

                                                     = \frac{1}{2} (3)(4)

                                                     =\frac{1}{2} (12)

                                                     = 6 cm^{2}

           In right angled triangular have two triangular faces,

                                                    = (2)(6)

                                                    =12 cm^{2}

Step:3

           Area of sloping rectangular face,

                                                     =lb

                                                     =(4)(5)

                                                     =20 cm^{2}

Step:4

                      Area of back side =(4)(3)

                                                     =12cm^{2}

Step:5

                 Area of bottom side =(4)(4)

                                                     =16cm^{2}

          From the equation (1),

                                                    =12+20+12+16

                                                    = 60cm^{2}

Result:

           The surface area of the given right angled triangular prism is 60 square centimeters (cm^{2}).

In the system of equations, r and s are constants. If the system has infinitely many solutions, what is the value of rs?
exis [7]

Answer:  B) -48

Step-by-step explanation:

If the system of two linear equations a_1x+b_1y=c_1\ \&\ a_2+b_2y=c_2 has infinitely many solutions , then

\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}=k

For the given system of linear equations : rx-sy=26\\4x+3y=13

We , will have

\dfrac{r}{4}=\dfrac{-s}{3}=\dfrac{26}{13}=2\\\\\Rightarrow\ r= 4\times2=8\ \ \&\ \ s=2\times-3=-6

The value of rs=(8)\times-6=-48

Hence, the value of rs is -48.

Thus , the correct option is B) -48.

Answer:

(3X8) - 4 + 2 - 12

Step-by-step explanation:

Following the order of operations solve:

(24) - 4 + 2 - 12

20 + 2 - 12

22 - 12

10

Don't feel bad, this is an odd question and the parenthesis do not seem to be required. Following the order of operations would result in the same answer anyway...

Odd.

A local clothing store sells jeans and shirts. The store makes a $10 profit on the sale of jeans and $3 profit on the sale of th
Zepler [3.9K]

Answer:

An inequality to model the situation is :   ( 10 m +  3 n)  ≥  150

Here, m : The number of jeans sold

          n : The number of shirts sold.

Step-by-step explanation:

Here, the profit on each sale of jeans = $ 10

The profit on each sale of shirt = $ 3

The profit needed to be made = AT LEAST $150

Now, here: Let us assume the number of jeans sold  = m

And, The number of shorts sold  =n

So, the profit on m jeans = m  x ( Profit on 1 jeans) = m x ( $ 10)  = 10 m

So, the profit on n shirts = n  x ( Profit on 1 shirt) = n x ( $ 3)  = 3 n

⇒ The total profit on m jeans + n shirts  = ( 10 m +  3 n)

But, according to the question, the profit should AT LEAST $150.

⇒ TOTAL PROFIT  ≥ $ 150

⇒  ( 10 m +  3 n)  ≥  150

Hence, an inequality to model the situation is :   ( 10 m +  3 n)  ≥  150
