we are given

$sin(\theta)=cos(73)$

we have to find theta

so, firstly we can write sin in terms of cos

$sin(\theta)=cos(90-\theta)$

now, we can set it equal

$cos(90-\theta)=cos(73)$

Since, both sides are cos

so, we can set angles equal

$90-\theta=73$

now, we can solve for theta

we get

$\theta=17$ ..............Answer

If you roll one die and flip one coin, what is the probability of rolling a 2 and flipping a head? Why?

Nezavi [6.7K]

Answer:

Probability of rolling a 2 and flipping a head will be $\frac{1}{12}$

Step-by-step explanation:

If we roll one die then probability to get any one side is $\frac{1}{6}$

Therefore, probability to get 2 by rolling the die will be P(A) = $\frac{1}{6}$

Now we flip a coin then getting head or tale probability is $\frac{1}{2}$

Or probability to get head by flipping the coin P(B) = $\frac{1}{2}$

Probability of happening both the events (rolling a 2 and flipping a head) will be denoted by

P(A∩B) = P(A)×P(B)

= $\frac{1}{6}\times \frac{1}{2}$

= $\frac{1}{12}$

Therefore, probability of rolling a 2 and flipping a head will be $\frac{1}{12}$

Kylie has lemon and watermelon in a ratio of 10:71. How many watermelon does she have if she has 20 lemons

kkurt [141]

Answer:

She will have 142 watermelons

Step-by-step explanation:

First let's put our ratio

10 : 71

Since our lemons are now 20 instead of 10 we will divide 20 by 10 to see how many time we multiplied it by.

$20 \div 10$

which equals 2

To find our water melon we will multiply it by 2

$71 \times 2$

which equals 142

She will have 142 watermelons

What is 3y+5x=-15 in slope-intercept form?

Sphinxa [80]

3y + 5x = -15

3y = -5x - 15 (Subtract 5x from both sides)

y = -5/3x - 5 (Divide everything by 3)
