If you divide the 24 delivery vans into 8 groups that means the truck dealer sells 8 trucks

A triangle has an angle that measures 90°. What type of triangle could it be? (Choose all that apply)

OLEGan [10]

Right and scalene. A right triangle has an angle that measures to be 90° and using the pythagorean theorem, we know that the triangle is scalene, meaning that all three sides have different side lengths. (:

A designer is making a rectangular prism box with maximum volume, with the sum of its length, width, and height 8 in. The length

Sever21 [200]

Answer:

width = 1.8 in

length = 3.6 in

height = $8-3w =8-3(1.8)= 2.6 in$

Step-by-step explanation:

A designer is making a rectangular prism box with maximum volume, with the sum of its length, width, and height 8 in

Let l , w and h are the length , width and height

$l +w+h=8\\l=2w$

Plug it in the first equation

$2w+w+h=8\\3w+h=8\\h=8-3w$

volume the box is length times width times height

$volume = (2w)(w)(8-3w)\\16w^2-6w^3$

To get maximum volume we take derivatived

$v'=32w-18w^2$

set the derivative =0 and solve for w

$0=32w-18w^2\\0=-2w(9w-16)\\w=0 , w= \frac{16}{9}$

width = 1.8 in

length = 2w= 3.6 in

height = $8-3w =8-3(1.8)= 2.6 in$

A publisher needs to send many books to a local book retailer and will send the books in a combination of small and large boxes.

mote1985 [20]

Answer:

5 large boxes

3 small boxes

Step-by-step explanation:

Create two equations to represent the problem.

let "a" be the number of small boxes

let "b" be the number of large boxes

20a + 40b = 260 This equation shows the numbers of books

a + b = 8 This equations shows the number of boxes

Solve the system of equations (solve for a and b). We can solve using the substitution method.

Rearrange a + b = 8 to isolate one of the variables.

a = 8 - b New equation that represents "a"

Since we know an equation for "a", we can substitute what "a" equals into the other equation. There will only be one variable in the equation, so we can solve by isolating. Isolate by doing reverse operations.

Substitute "a" for 8 - b

20a + 40b = 260

20(8 - b) + 40b = 260 Distribute 20 over the brackets by multiplying

160 - 20b + 40b = 260 Collect like terms (numbers with same variables)

160 + 20b = 260 Start isolating "b". Subtract 160 from both sides

20b = 260 - 160

20b = 100 Divide both sides by 20

b = 5 Number of large boxes

Substitute "b" for 5 in the simplest equation

a + b = 8

a + 5 = 8 Subtract 5 from both sides to isolate "a"

a = 8 - 5

a = 3 Number of small boxes

Therefore there were 5 large boxes and 3 small boxes sent.
