Answer:

∅=30°

Step-by-step explanation:

$sin$ ∅ $=\frac{1}{\sqrt{3} }sin60^{0}$

sin∅= $\frac{\frac{\sqrt{3} }{2} }{\sqrt{3} } =\frac{\sqrt{3} }{2\sqrt{3} }=\frac{1}{2}$

∅= $sin^{-1}(\frac{1}{2})= 30^{0}$

Help plz with this math problem. I’m so confused

Lunna [17]

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).

The equation to find the slope is:

m = $\frac{y2 - y1}{x2 - x1}$

Let's substitute in our values:

m = $\frac{-2 - -4}{6 - 3}$

Remember that two negatives make a positive, let's solve for m:

m = $\frac{2}{3}$

Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).

Therefore we can determine that b = -6.

Let's substitute our value for m and our value for b into the slope-intercept formula:

y = mx + b

y = $\frac{2}{3}$ x + -6

There's your final answer! I hope this helps, have a great night. :)

If Morgan and Kira have a number of jelly beans in a ratio of 5 : 3. Kira and Mann have a

castortr0y [4]

Answer:

Step-by-step explanation:

Kira has 3/8 of the total of Jelly Beans available. Morgan has the other 5/8

So if there are 56 Jelly beans in total 3/8 * 56 = 21 which would be Kira's share.

Morgan would have 5/8 * 58 = 35 Jelly beans (Not that this is really relevant).

Now Kira and Mann have a ratio of 6:1 which means that she has 6/7 of the total between those two. He therefore must have 1/7 of the total.

Her total is 21.

1/7 of 21 = 3

Therefore Mann would have 3 jelly beans.

3/8 * 1/7 is the total the number of Jelly Beans that he would have if the total was N

N(3/8 * 1/7) = N (3/56)

A trapezoid has an area of 13.5 square inches. If the bases are 3 and 6 inches what is the height?

liraira [26]

Well the formula is : b1+b2/2 (h)

so the height would be solved as :
13.5 = 3+6/2 (h)
13.5 = 9/2 (h)
h = (13.5)/(9/2)
h = (13.5) x (2/9) *reciprocal*
h = (27) / (9)
h = 3

In a factory, 3.25% of the jars of peanut butter produced contains less peanut butter than is advertised on the label. The facto

marshall27 [118]

Answer:

936 jars of peanut butter contain less peanut butter than usual.

Step-by-step explanation:

1. First, we need to find how many jars of peanut butter that contain less peanut butter than advertised are produced every hour.

The factory produces 1200 jars of peanut butter every hour

3.25% of those jars have less peanut butter than advertised

So: multiply $(1200*.0325)$ (the decimal form of the percent) to find the amount of peanut butter jars that contain less peanut butter than advertised.

$(1200*.0325) = 39$

So the factory produces 39 jars of peanut butter that contain less peanut butter than advertised.

2. Second, we need to find how many jars of peanut butter that contain less peanut butter than advertised in three 8 hour work days.

Lets add these work days together to find the total amount of hours: $(8 + 8 + 8) = 24$

So: three 8 hour work days totals to 24 hours

Since the factory produces 39 jars of peanut butter that contain less peanut butter than advertised per hour. Multiply $(24 * 39)$ to find the total amount of jars produced in three 8 hour work days.

$(24 *39) = 936$

A total of 936 peanut butter jars are produced in three 8 hour work days that contain less peanut butter than advertised.

3. If you want to double check your work do the following.

Since the factory produces 1200 jars an hour and 24 hours total three 8 hour work days. Multiply $(1200*24) = 28800$

So there is a total of 28800 jars produced in three 8 hour work days.

Then you can multiply 28800 by 3.25% of jars that contain less peanut butter to find the total amount of peanut butter jars that contain less peanut butter in three 8 hour work days.

$(28800 * .0325) = 936$

Consider the following linear equations. y = 2x + 5 y = 2x - 3 Which statement below if True?

Fantom [35]

Answer:

Option B is correct

Step-by-step explanation:

The equation of a straight line is given as;

y = mx + b

where m is the slope and b is y-intercept

Let’s evaluate the options one after the other;

A. This is wrong as they both have same slope of 2

C. The y-intercepts are not the same

One is 5, the other is -3

D. This is wrong, the line cannot be the same

Option B is correct

The y-intercept of both varies

While 1 is already appreciated, the other is coming back
