Answer:

sin(50deg) = 3/c

Step-by-step explanation:

Applying the trigonometry ratio, SOH, the equation that can be used to solve for c is: sin (50°) = 3/c.

To solve a right triangle, any of the ratios, SOH CAH TOA, can be applied.

Thus, given right triangle ABC, where:

Apply SOH:

sin ∅ = opp/hyp

sin (50°) = 3/c

Therefore, applying the trigonometry ratio, SOH, the equation that can be used to solve for c is: sin (50°) = 3/c.

Answer:

Step-by-step explanation:

To solve this problem, we just need to find the common point of these linear function, beacuse they form a piecewise function which is continuous according to the problem, that means they are related by one common point.

Let's solve the following expression [tex]f(x)=g(x)[/tex], where [tex]f(x) =2x+2[/tex] and [tex]g(x)=4x[/tex]. So,

[tex]2x+2=4x\\2=4x-2x\\2x=2\\x=1[/tex]

Which means [tex]n=1[/tex], that is, if the n is greater than 1, then the function is defined by [tex]f(x)[/tex], if the n is least or equal than 1, then the functioni is defined by [tex]g(x)[/tex]

Therefore, the right answer is D.

Answer:

1. A, -1

2. D, 1

3. B, It is discontinuous because there is a value a for which f(a) is not defined 4. D, It is discontinuous because there is a value a such that lim f(x) does not exist

Answer:

400

Step-by-step explanation:

The number of eagle quarters likely to be in the bag is 200.

Option B is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of quarters = 500

Out of the 10 quarters.

Eagle quarters = 4

This means,

Percentage of eagle quarters,

= 4/10 x 100

= 40%

Now,

40% of 500 quarters.

= 40/100 x 500

= 200

Thus,

The full bag is likely to have 200 eagle quarters.

Answer:

10 grams or 0.010kg

Step-by-step explanation:

The mass of the bag used to make flour is 2.26 kg = 2260 grams

Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.

Therefore: [tex]\frac{2260}{450} = 5.02[/tex]

We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.

Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.

Note: 2260 -2250 = 10 grams.

Subtract, in order to find how many you have left.

Hope this helps.

After making one batch of muffins, Maria will have 1.8 kg of flour remain.

What is 1 kg when it is converted into grams?

1 kg will be 1000 grams when converted.

Given,

Maria bought 2.26 kg of flour = 2260 grams of flour.

To make 1 batch of muffins, Maria needs 450 grams of flour.

Therefore, the flour Maria has after making one batch of muffin = (2260 - 450) grams = 1810 grams.

Answer:

The value of x is 37°.

Step-by-step explanation:

Given that the total angles in a triangle is 180°. In order to find the x value, you have to substract 98° and 45° from 180° :

[tex]x + 98 + 45 = 180[/tex]

[tex]x = 180 - 98 - 45[/tex]

[tex]x = 37[/tex]

Answer: 37

Step-by-step explanation:

If you add in all numbers inside the triangle, it should be equal to 180 degrees meaning x + 98 + 45 = 180.

To solve the unknown, we must first add in the numbers:

x + 143 = 180

To get the variable by itself, we must subtract 143 to both sides which gives us 37 degrees.

Now that we know that x is equal to 37, we should make sure it is the right answer, to do that, we need to replace x with 37:

37 + 98 + 45 = 180

By adding in all the numbers, we should get 180.
