insulin comes in 10 cubic centimeter(cc) vials labeled in the number of units of insulin per cubic centimeter of fluid. A vial m

Sergio [31]

Answer:

8.25 cc fluid should be drawn into the syringe from the U40 vial.

Step-by-step explanation:

The amount of a U40 vial insulin fluid is 10 cc.

A vial marked U40 has 40 units of insulin per cubic centimeter of fluid.

Suppose, if a patient needs 33 units of insulin, then $x$ cc fluid should be drawn.

So, according to the ratio of "cubic centimeter" to "the units of insulin", the equation will be.........

$\frac{x}{33}=\frac{10}{40}\\ \\40x=330\\ \\ x=\frac{330}{40}=8.25$

So, 8.25 cc fluid should be drawn into the syringe from the U40 vial.

Find the probability.

vitfil [10]

Answer:

82%

Step-by-step explanation:

how i did it was 12 + 15 + 6 is 33 and then 12 + 15 is 27 so it's 27 out of 33. then to find the percentage just divide 27 by 33 and multiply the answer by 100.

Use matrices to determine the coordinates of the vertices of the reflected figure. Then graph the pre-image and the image on the

Troyanec [42]

Answer:

The coordinates of the vertices of the reflected figure are :

R' is (5 , -2) , S' is (3 , 5) , T' is (-7 , 6) ⇒ the right answer is (d)

Step-by-step explanation:

* When you reflect a point across the line y = x, the x-coordinate

and y-coordinate change their places.

- If the point is (x , y) then its image is (y , x)

* If you reflect over the line y = -x, the x-coordinate and y-coordinate

change their places and their signs

- If the point is (x , y) then its image is (-y , -x)

* Lets study the matrix of the reflection about the line y = x

- The matrix of the reflection about the line y = x is

$\left[\begin{array}{cc}0&1\\1&0\end{array}\right]$

- Because the x-coordinate and y-coordinate change places.

* Now lets solve the problem

- We will multiply the matrix of the reflection about y = x

by each point to find the image of each point

- The dimension of the matrix of the reflection about y = x

is 2×2 and the dimension of the matrix of each point is 2×1,

then the dimension of the matrix of each image is 2×1

∵ The point R is (-2 , 5)

∴ $R'=\left[\begin{array}{cc}0&1\\1&0\end{array}\right]\left[\begin{array}{cc}-2\\5\end{array}\right]=$

$\left[\begin{array}{c}(0)(-2)+(1)(5)\\(1)(-2)+(0)(5)\end{array}\right]=\left[\begin{array}{c}5\\-2\end{array}\right]$

∴ R' is (5 , -2)

∵ The point S is (5 , 3)

∴ $S'=\left[\begin{array}{cc}0&1\\1&0\end{array}\right]\left[\begin{array}{c}5\\3\end{array}\right]=$

$\left[\begin{array}{c}(0)(5)+(1)(3)\\(1)(5)+(0)(3)\end{array}\right]=\left[\begin{array}{c}3\\5\end{array}\right]$

∴ S' is (3 , 5)

∵ The point T is (6 , -7)

∴ $T'=\left[\begin{array}{cc}0&1\\1&0\end{array}\right]\left[\begin{array}{c}6\\-7\end{array}\right]=$

$\left[\begin{array}{c}(0)(6)+(1)(-7)\\(1)(6)+(0)(-7)\end{array}\right]=\left[\begin{array}{c}-7\\6\end{array}\right]$

∴ T' is (-7 , 6)

* Lets look to the figures to find the right answer

∵ The R' is (5 , -2) , S' is (3 , 5) , T' is (-7 , 6)

∴ The right answer is (d)

A large pizza at palanizo pizzeria costs 6.80$ plus 0.90$ for each topping. The cost of a large cheese pizza at guido’s pizza is

r-ruslan [8.4K]

we are going to create a table in excel and we will assign different values of topping to know when the price is equal in both pizzerias

see the attached figure

the answer is

5 toppings from palanzio’s pizzeria

6 toppings from guido’s pizza

cost palanzio’s pizzeria----> 6.80+0.90*5-----> $11.30

cost guido’s pizza------> 7.40+0.65*6----------> $11.30
