The prism shown has a volume of 35 cm.

Vesna [10]

Answer:

1.25cm

Step-by-step explanation:

Complete question:

The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section

length=7cm

width = 4cm

The volume of the prism is expressed as;

Volume = Base Area * Height

Given

Volume of the prism = 35cm^3

Base Area = length * width

Base Area = 7cm * 4cm

Base Area = 28cm^2

Substitute the given values into the formula

35 = 28* Height

Cross multiply

35 = 28 * Height

35 = 28 Height

Height = 35/28

Height = 1.25cm

Hence the height of the triangular cross section is 1.25cm

Help math look at pic

Sloan [31]

Answer: $\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}$

Step-by-step explanation:

Given the system of equation

$1)~y=-(x+2)^2+1$

$2)~y=2x+5$

Expand the parenthesis of the 1) equation

$y=-(x+2)^2+1$

$y=-(x^2+4x+4)+1$

$y=-x^2-4x-4+1$

$y=-x^2-4x-3$

Current System

$1)~y=-x^2-4x-3$

$2)~y=2x+5$

Substitute the y value of the 1) equation with the 2) equation

$2x+5=-x^2-4x-3$

Add ( x² + 4x + 3) on both sides

$2x+5+(x^2+4x+3)=-x^2-4x-3+(x^2+4x+3)$

$2x+5+x^2+4x+3=0$

Combine like terms

$x^2+2x+4x+5+3=0$

$x^2+6x+8=0$

Factorize the quadratic equation

$(x+4)(x+2)=0$

$x=-4~\text{or}~x=-2$

Substitute the x values into one of the equations to find the y value

$y=2x+5$

$y=2(-4)+5=-8+5=-3$

$y=2(-2)+5=-4+5=1$

Therefore, the two solutions are:

$\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}$

Hope this helps!! :)

How many pounds of candy that cells for $0.66 per Ib must be mixed with candy that sells for $1.31 per Ib to obtain 9 Ib of a mi

faltersainse [42]

Answer: $\frac{306}{65}$ pounds

Step-by-step explanation:

Let x pounds of $ 0.66 per lb candies mixed with y pounds of $ 1.31 per lb candies to obtain 9 lb of $ 0.97 per lb candies,

Hence, we can write,

x + y = 9 ------- (1)

And, 0.66 of x + 1.31 of y = 0.97 of (x + y)

⇒ 66 x + 131 y = 97 (x+y)

⇒ 66 x +131 y - 97 x - 97 y = 0

⇒ -31 x + 34 y = 0 ------(2)

By solving equation (1) and (2)

We get,

$x=\frac{306}{65}$ and $y=\frac{279}{65}$

Hence, the quantity of 0.66 per lb candies = $\frac{306}{65}$ pounds
