Answer:

1) The shoes were purchased at a 40% discount.

2) In order to treat 150 patients, the health department will require 9 vials of the malaria serum.

Step-by-step explanation:

1) If the original cost of the pair of shoes was $40, and you paid $24, then we want to set up a proportion to solve for the discounted percentage.

The discounted percentage is what you DID NOT pay, therefore we will find the amount of money saved first before setting up our proportion

$40 - $24 = $16

Meaning you did not pay that extra $16

Using that deficit, let's set up a proportion in terms of the total:

16/40 = 0.4

To find the percentage that was discounted we must multiply our proportion by 100%

0.4 *100% = 40%

Therefore, the shoes you had bought were on sale for 40% off.

2) If the health department expects 6 vials of malaria serum to treat 100 patients then our proportion of vials to patients becomes

6/100

To solve for how many vials will be required to treat 150 patients, we must equate our expected proportion to one with those 150 patients

6/100 = x/150 Where x denotes the number of vials needed.

Multiply both sides by 150 to isolate x

900/100 = x Reduce the fraction

9 = x

Therefore, in order to treat 150 patients, the health department will require 9 vials of the malaria serum.

<B Round your answer to the nearest hundredth. 2 А 3 ? B

Svet_ta [14]

Answer:

∠ B ≈ 41.81°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin B = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{2}{3}$ , thus

B = $sin^{-1}$ ( $\frac{2}{3}$ ) ≈ 41.81° ( to the nearest hundredth )

Identify the domain and range for the table from problem #5 of your assignment. Also, determine if it represents a function.

Lana71 [14]

Answer:

Domain: {4,5,7,10}

Range: {2,4,8}

Not a function

Step-by-step explanation:

The domain is all the x-values.

The range is all the y-values.

However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.

4. Two points on a line are (-10, 1) and (5, -5). If

Vsevolod [243]

Answer:

The x-coordinate of another point is zero

Step-by-step explanation:

step 1

Find the slope between the two given points

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$(-10,1),(5,-5)$

substitute in the formula

$m=\frac{-5-1}{5+10}$

$m=\frac{-6}{15}$

Simplify

$m=-\frac{2}{5}$

step 2

Find the x-coordinate of another point

we have

(x,-3)

we know that

If the other point is on the line, then the slope between the other point and any of the other two points must be the same

Find the slope between the points

$(x,-3),(5,-5)$

Remember that

$m=-\frac{2}{5}$

substitute in the formula

$-\frac{2}{5}=\frac{-5+3}{5-x}$

$-\frac{2}{5}=-\frac{2}{5-x}$

the denominators must be the same

$5=5-x$

$x=0$

therefore

The x-coordinate of another point is zero

Mrs moretti is making welcome bags to give to the 18 students in his homeroom on the first day of school. He puts m mechanical p

julsineya [31]

Answer:

b.) 18(m+2m)

d.) 18m+18(2m)

e.) 54m

Step-by-step explanation:

Given;

total number of Mr Moretti's students = 18

number of mechanical pencils for each student = m

total number of mechanical pencils for all the students = 18m

number of regular pencils for each student = 2m

total number of regular pencils for all the students = 18(2m)

The total number of pencils given to all the 18 students by Mr Moretti is given by;

T = Total mechanical pencils + total regular pencil

T = 18m + 18(2m)

T = 18(m + 2m)

T = 18(3m)

T = 54m

Therefore, based on the expressions above, the correct options include;

b.) 18(m+2m)

d.) 18m+18(2m)

e.) 54m
