Yao Xin puts \dfrac{3}{10} 10 3 ? start fraction, 3, divided by, 10, end fraction liters of potting soil in each pot for plantin

slega [8]

Answer:

She can fill 19 pots.

Step-by-step explanation:

Yao Xin puts $\frac{3}{10}$ liters of potting soil in each pot.

Suppose, the number of pots Yao Xin can fill is $x$

So, the total amount of potting soil in $x$ number of pots will be: $\frac{3}{10}x$ liters.

Given that, she has $5\frac{2}{3} or \frac{17}{3}$ liters of potting soil. So, the equation will be........

$\frac{3}{10}x= \frac{17}{3} \\ \\ x=\frac{17}{3}* \frac{10}{3}= \frac{170}{9}=18\frac{8}{9}$

So, she can fill pots.

I need help with this math question 3f+9<21

liubo4ka [24]

I am assuming you want to find the simplest form of the inequality.

1. $3f + 9 \ \textless \ 21$
2. $3f < 12$
3. $f < 4$

1. Start
2. Subtract 9 from each side
3. Divide both sides by 3

Verify: cos(2A)=(cotA-tanA)/cscAsecA

kolbaska11 [484]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

cot A = $\frac{cosA}{sinA}$ , tanA = $\frac{sinA}{cosA}$ , cscA = $\frac{1}{sinA}$ , secA = $\frac{1}{cosA}$

Consider the right side

$\frac{cotA-tanA}{cscAsecA}$

= $\frac{\frac{cosA}{sinA}-\frac{sinA}{cosA} }{\frac{1}{sinA}.\frac{1}{cosA} }$

= $\frac{\frac{cos^2A-sin^2A}{sinAcosA} }{\frac{1}{sinAcosA} }$

= $\frac{cos^2A-sin^2A}{sinAcosA}$ × sinAcosA ( cancel sinAcosA )

= cos²A - sin²A

= cos2A

= left side ⇒ verified
