Help me solve this please

drek231 [11]

Answer:

x is 46.67

y is 28.4°

Step-by-step explanation:

To solve for x we use sine

sin ∅ = opposite / hypotenuse

AC is the opposite

x is the hypotenuse

so we have

sin 59° = 40 / x

x sin 59 = 40

Divide both sides by sin 59

x = 40/sin 59

x = 46.67

To solve for y we also use sine

sin y = 30/ 63

y = sin^-1(30/63)

y = 28.4°

Hope this helps you

Which fraction is equivalent to StartFraction 2 Over 6 EndFraction? StartFraction 3 Over 7 EndFraction, because StartFraction 2

irinina [24]

Question:

Which fraction is equivalent to $\frac{2}{6}$ ?

- $\frac{3}{7}$ because $\frac{2}{6}= \frac{2 + 1}{6 + 1}$

- $\frac{3}{9}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

- $\frac{3}{12}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

- $\frac{3}{8}$ because $\frac{2}{6}= \frac{1}{2} = \frac{2+1}{6+2} = \frac{3}{8}$

Answer:

- $\frac{3}{9}$ because $\frac{2}{6}= \frac{1}{3}$ and $\frac{1}{3} = \frac{3}{9}$

Step-by-step explanation:

Two fractions are said to be equal if and only if they give the same value when simplified.

The equivalent of $\frac{2}{6}$ is as explained in the selected option;

First, divide numerator and denominator by 2

$\frac{2/2}{6/2}$

Then simplify

2/2 = 1 and 6/2 = 3; So;

$\frac{2/2}{6/2} = \frac{1}{3}$

Multiply numerator and denominator by 3

$\frac{1*3}{3*3} = \frac{3}{9}$

Hence, $\frac{2}{6}$ is equivalent to $\frac{3}{9}$

Find the probability of drawing a Ace or diamonds on the first draw, replacing it and drawing a 6 card on the second draw

coldgirl [10]

Step-by-step explanation:

do you have a chart

to find probability is to add up all the numbers on the chart or the question that have been ask

when the question ask "draw or chance" you do this

example: Jack has 7red marbles 4 green, 2 yellow and 5 grey in a bag what is the chance of him pulling out 7 red marbles?

Well you would add up every number you see there

7+4+2+5=18

the question what is the chance the chance is the number over the amount of marbles that are in the bag

answer= 7/18

Patricia baked some cupcakes for sale. she put half of the cupcakes equally into 6 big boxes and the other half equally into sma

mojhsa [17]

Answer:

The answer is given below

Step-by-step explanation:

a)

Let us assume Patricia baked x number of cakes. She put half of the cupcakes (i.e x/2) equally into 6 big boxes.

6 big boxes contained $\frac{x}{2}$ cakes, therefore 1 big box would contain $\frac{x}{2}/6=\frac{x}{12}$ cakes.

Let us assume she put the other half into 14 small boxes, therefore each small box would contain $\frac{x}{2}/14=\frac{x}{28}$ cakes.

There were 45 cupcakes in 3 big boxes and 8 small boxes altogether. That is: $3(\frac{x}{12} )+8(\frac{x}{28})=45\\ 84x+96x=15120\\180x=15120\\x=84$

Therefore Patricia baked 84 cup cakes

b)

She sold all the small boxes and collected $189, i.e she sold 14 small box for $189. Each small box = $189/14 = $13.5
