Answer:

8.88

Step-by-step explanation:

With reference angle 42°

hypotenuse (h) = 12

base (b) = x

Now

cos 42° = b / h

0.74 = x / 12

x = 0.74 * 12

x = 8.88

Find the value of x I’d appreciate if you could explain as well if not that’s fine

Answers

All the angles in a circle equal to 360 degrees. So basically just add up all the known values: 23+23+15=61 and then subtract that from 360: 360-61=299.

You can also do 23+23+15+x=360. Adding it all becomes 61+x=360, subtract 61 from both sides of the equation, and you get x=299.

(Something to help remember is that the angle is obtuse, meaning it’s automatically more than 90 degrees, hope this helps!)

Answers

Answer:

c = 2.99m+ 6.85

Step-by-step explanation:

one time fee of 6.85

2.99 per movie rental

in other words you must pay 6.85

and 2.99 times the number of movies you watch

m = movies watched

c = cost

therefore

c = 2.99m+ 6.85

watching 13 movies at movie mania would mean that m (movies watched) would be 13

put that into the equation:

c = 6.85+ 2.99(13)

c = 6.85+ 38.87

c = 45.72

how do I solve this

Answers

Answer:

4 hours

Step-by-step explanation:

120-72=48

48÷12=4

Answer:

Step-by-step explanation:

The total amount was $120.

A portion of the $120 was for parts.

The rest of the $120 was for service. Service cost $12 per hour.

Start with $120.

Subtract $72 to find the amount spent on service.

$120 - $72 = $48

$48 was spent on service.

The service costs $12 per hour.

$48/($12/hour) = 4 hours

Answer: 4 hours

Check:

$72 in parts + 4 hours * $12/hour = $72 + $48 = $120

4 hours is correct.

An angle measures 72.2° less than the measure of its complementary angle. What is the
measure of each angle?
º and°

Answers

Answer:

We have the angles as;

8.9 and 72.2

Step-by-step explanation:

When two angles are complementary, they add up to 90

Let the first angle be x , the second angle is 72.2 degrees less and it is x-72.2

Thus, mathematically;

x + x - 72.2 = 90

2x = 90+ 72.2

2x = 162.2

x = 81.1

The other will be

81.1 - 72.2 = 8.9

Y=-1

Step-by-step explanation:

-4(y-2)

-4y+8=12

-8. -8

-4y=4

-4. -4

y=-1

Answer: Y = -1

Step-by-step explanation:

This is solved using the distributive property.

1. Distribute, so now it should look like -4y + 8 = 12

2. Now subtract the 8 from both sides to isolate -4y = 4

3. Divide -4 on both sides to get y = -1

A store buys an item for $94. The store then prices the item to sell to customers. What is the selling price (in dollars) the store sells the item to customers for after applying a 62% markup? If necessary, round the answer to the closest hundredth.

Answers

Answer:

$152.28

Step-by-step explanation:

In order to determine the markup, multiply the original price by 62%

94 x 62% = 94 x .62 = 58.28

In order to determine the sale price, add the markup to the original price.

94 + 58.28 = $152.28

Ice core data suggests the Earth should actually be cooling if it were following its natural cycles. The trend can be best visualized by comparing each years average temperature with the long- term average. Figure 1 shows observations of the worlds annual average temperature made by the National Oceanic and Atmospheric Administration (NOAA). In recent decades, the years have always been hotter. Over geologic time, the Earths average temperature has changed as a result of the suns output, the tilt and position of the Earth in its orbit, and the concentration of greenhouse gases. Scientists have developed a good understanding of the natural variations in these factors by examining different data sources in order to estimate ancient temperatures. Observations tell us that these natural factors have not been changing over the last hundred years or so in a way that would explain the observed temperature increases.In contrast, greenhouse gases have been changing in a way that can explain the observed temperature increases. Figure 2 shows the change in atmospheric CO2 concentration over the last thousand years. At the Scripps Institute of Oceanography in Hawaii researchers have been sampling pristine mountaintop air every month since 1958. Their observations show that both the concentration and isotopic composition of CO2 is changing, and is consistent with manmade sources, including the carbon emissions from burning fossil fuels. The industrial revolution marked a drastic increase in CO2 concentrations in the atmosphere when humans began using fossil fuels on a large scale.Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. CO2 along with other gases are known as greenhouse gases. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.Give evidence and reasoning!!
