Answer:

13 sticks of butter would weigh 3 pounds and a quarter which can also be expressed as 3.25 pounds!

Step-by-step explanation:

If one stick weighs a quarter then that means 4 sticks would weigh a full pound. When you multiply this by 3 you get 12 sticks of butter (3 pounds) and the 13th stick would add a quarter.

Answer:

13 l of 15%, 13 l of 25%, 26 l of 70%

Step-by-step explanation:

solutions:

15%, 25% and 70%

final solution:

52 l of 45%

This includes 0.45*52l= 23.4 l acid

Let's assume:

amount of 15% solution= x
amount of 25% solution= y
amount of 70% solution= z
and we have z=2y

so there are 2 equation:

x+y+z=52

0.15x+0.25y+0.7z=23.4

x+y+2y= 52 ⇒ x+3y= 52 ⇒ x= 52- 3y

0.15x+0.25y+1.4y=23.4

0.15x+1.65y=23.4
0.15*(52-3y)+1.65y=23.4
7.8-0.45y+1.65y=23.4
1.2y=23.4-7.8
1.2y= 15.6

y=15.6/1.2
y= 13 l

--------

x= 52- 3*13= 13 l
z= 2y= 2*13= 26 l

A rectangular prism has a length of 13ft and a width of 16ft.

IrinaK [193]

Considering the volume of the rectangular prism, it is found that it's height is of 4.5 ft.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism of length l, width w and height h is given by:

$V = lwh$

In this problem, the measures given are as follows:

l = 13 ft, w = 16 ft, V = 936 ft³.

Hence, the height, in ft, is found as follows:

$V = lwh$

$13 \times 16 \times h = 936$

$h = \frac{936}{13 \times 16}$

$h = 4.5$

A 2-column table with 5 rows. the first column is labeled x with entries negative 4, negative 1, 0, 2, 3. the second column is l

Licemer1 [7]

The linear function that models the data in the table is $y = \frac{3}{2}x + 1$

<h3>How to determine the linear model?</h3>

The table of values is given as:

x y

-4 -6

-1 -1

0 1

2 4

3 7

The linear equation is calculated using:

$y = \frac{y_2 -y_1}{x_2 - x_1} * (x - x_1) + y_1$

So, we have:

$y = \frac{4 -1}{2 - 0} * (x - 0) + 1$

Evaluate the differences

$y = \frac{3}{2}x + 1$

Hence, the linear function that models the data in the table is $y = \frac{3}{2}x + 1$
