Answer:

425 milliliters of compound A are needed

Step-by-step explanation:

We were told that $5$ milliliters of compound A and $6$ milliliters of compound B is needed to make the drug.

This means that each drug contains 11 milliliters of both compounds.

$\frac{935}{11}=85$ milliliters is the volume of each drug.

Therefore the chemist needed $5\times 85=425$ millilirteres of compound A.

Answer:

$\frac{-47}{6}$ = $7.833$

Step-by-step explanation:

Expression given is:

$-4\frac{2}{3} -(3\frac{1}{6})$

Now change the mixed fraction to improper fractions;

$-\frac{14}{3} -\frac{19}{6}$

Now take a common denominator:

$-\frac{28}{6} -\frac{19}{6}$

Now we can simplify the the above equation:

$\frac{-28-19}{6}$

$\frac{-47}{6}$ = $7.833$

Jamie needs to build a fence around his garden, as illustrated by polygon ABCDEF on the coordinate grid below. If each unit repr

NNADVOKAT [17]

Answer:

C. 26 yards

Step-by-step explanation:

Jamie's fence total length = perimeter of the polygon

Perimeter of the polygon = AB + BC + CD + DE + EF + FA

AB, FA and DE can be worked accordingly as shown below:

AB = |-5 - 0| = 5 units

FA = |5 - 2| = 3 units

DE = |1 -(-2)| = 3 units

BC, CD, and EF can be calculated using the formula $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Distance between B(0, 5) and C(4, 2):

$BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$B(0, 5) = (x_1, y_1)$

$C(4, 2) = (x_2, y_2)$

$BC = \sqrt{(4 - 0)^2 + (2 - 5)^2}$

$BC = \sqrt{(4)^2 + (-3)^2}$

$BC = \sqrt{16 + 9} = \sqrt{25}$

$BC = 5 units$

Distance between C(4, 2) and D(1, -2)

$CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$C(4, 2) = (x_1, y_1)$

$D(1, -2) = (x_2, y_2)$

$CD = \sqrt{(1 - 4)^2 + (-2 - 2)^2}$

$CD = \sqrt{(-3)^2 + (-4)^2}$

$CD = \sqrt{9 + 16} = \sqrt{25}$

$CD = 5 units$

Distance between E(-2, -2) and F(-5, 2):

$EF = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$E(-2, -2) = (x_1, y_1)$

$F(-5, 2) = (x_2, y_2)$

$EF = \sqrt{(-5 -(-2))^2 + (2 -(-2))^2}$

$EF = \sqrt{(-3)^2 + (4)^2}$

$EF = \sqrt{9 + 16} = \sqrt{25}$

$EF = 5 units$

Total length of the wall in yards = 5 + 5 + 5 + 3 + 5 + 3 = 26 yards

A rectangular solid has sides of 4 cm, 6 cm, and 8 cm. What is its surface area?

gizmo_the_mogwai [7]

The surface are of a rectangular prism is:

A=2(xy+xz+yz), where x,y, and z are the dimensions of the prism, in this case:

A=2(4*6+4*8+6*8)

A=2(24+32+48)

A=2(104)

A=208 cm^2
