sergij07 [2.7K]

Which of the following accurately describes cot⁡(336°)

Options are

cot⁡(-336°)

cot⁡(24°)

cot⁡(-24°)

-cot⁡(-24°)

Answer : cot⁡(-24°)

In a circle the total angle is 360 degrees. 336 degree lies in fourth quadrant.

360 degree - 336 degree = 24 degree

+24° lies on first quadrant and -24° lies on fourth quadrant.

So cot(336) is same as cot(-24)

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get

MrRa [10]

Answer:

$Ivy = 24$

Step-by-step explanation:

Given

$Dennis : Ivy = 7 : 4$

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

$Dennis : Ivy = 7 : 4$ and

$Dennis = 42$

Substitute 42 for Dennis in $Dennis : Ivy = 7 : 4$

$42 : Ivy = 7 : 4$

Convert to fraction

$\frac{42}{Ivy} = \frac{7}{4}$

Cross Multiply:

$Ivy * 7 = 42 * 4$

Divide through by 7

$\frac{Ivy * 7}{7} = \frac{42 * 4}{7}$

$Ivy = \frac{42 * 4}{7}$

$Ivy = 6* 4$

$Ivy = 24$
