A. 2/5 because of you take 3/4 and roughly cut it in half, it would be 3/8 which is close to 2/5, but a little less since in the problem, you aren't completely cutting 15 people in half to get 8, so it is an estimate

If f(x) + g(x) = (f + g)(x), then we can simplify this by adding both functions together: ΙxΙ + 9 + (- 6). This makes ΙxΙ + 3. The absolute value of x can only be something that is greater than or equal to zero for the function to make sense. This means your answer is a.) (f + g)(x) ≥ 3.

If we are to make x small rugs, each of which takes 2 hours to dye, then the total time taken to dye the small rugs is 2x. Similarly for the y large rugs which each take 3 hours to dye, the total time for dyeing the large rugs is 3y. Therefore the total for all sizes of rugs is 2x + 3y. Finally, we have a maximum of 60 available hours for the dyeing, so the total time cannot exceed 60, and the final inequality is
2x + 3y < 60

Hi need help on hw plz help me out my questions is - a rectangle has a length of 14cm and width 9.5cm the length increased by 6%

sweet-ann [11.9K]

Answer:

Part a) $21.9\%$

Part b) $82.03\%$

Step-by-step explanation:

we know that

The original area of rectangle is equal to

$A=(14)(9.5)\ cm^{2}$

if the length is increased by 6% and the width is by 15%

then

the new area is equal to

$A=[1.06(14)][1.15(9.5)]\ cm^{2}$

$A=(1.06*1.15)(14)(9.5)\ cm^{2}$

$A=(1.219)(14)(9.5)\ cm^{2}$

The new area is (1.219) times the original area

Part a) Calculate the percentage change in area of the rectangle

$1.219-1=0.219$

convert to percentage

$0.219*100=21.9\%$

Part b) what is the original area as a percentage of the increased area of the rectangle?

Divide the original area by the increased area

$\frac{(14)(9.5)}{(1.219)(14)(9.5)} =\frac{1}{1.219} \\ \\=0.8203$

Convert to percentage

$0.8203*100=82.03\%$

PLEASE ANSWER I WILL MARK AS BRAINLIEST

Tomtit [17]

Answer:

Six

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

$V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}$

(c) Banana flavouring

$V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL }$

2. Calculate the total volume

Chlorpheniramine = 100 mL

Lidocaine = 59

Banana flavouring = <u> 2.5 </u>

TOTAL = 162 mL

3. Calculate the number of doses

$\text{Doses} = \text{162 mL} \times \dfrac{\text{1 dose}}{\text{10 mL}} = \text{16.2 doses}\\\\\text{You can't take a fraction of a dose, so the there are $\large \boxed{\textbf{16 doses}}$}$
