what is the best estimate

Answer:

Option D. is correct.

Step-by-step explanation:

[tex]\cot ^{\left(2\right)}\left(73^{\circ \:}\right)-\csc ^{\left(2\right)}\left(73^{\circ \:}\right)\\[/tex]

[tex]\csc \left(73^{\circ \:}\right)=\frac{1}{\sin \left(73^{\circ \:}\right)}[/tex]

[tex]=\cot ^2\left(73^{\circ \:}\right)-\left(\frac{1}{\sin \left(73^{\circ \:}\right)}\right)^2[/tex]

[tex]\left(\frac{1}{\sin \left(73^{\circ \:}\right)}\right)^2 = \left\frac{1}{\sin^2 \left(73^{\circ \:}\right)}\right[/tex]

[tex]=\cot ^2\left(73^{\circ \:}\right)-\frac{1}{\sin ^2\left(73^{\circ \:}\right)}[/tex]

Which is the same as...

Answer:

Equation: 7x + 8x = 180

x = 12

∠CBA = 84

∠CFH = 96

Step-by-step explanation:

We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.

We know that the sums of two angles on a straight line are going to be equal to 180.

∠CBA = 7x

∠CFH = 8x

To find the value of x, we must do the following:

7x + 8x = 180

15x = 180

15x/15 = 180/15

x = 12

Now we just substitute to find the angle measures:

∠CBA = 7 · 12 = 84

∠ CFH = 8 · 12 = 96

Step-by-step explanation:

Tan(30) = 1/2

Longer leg = 20

Hypotenuse = 10*sqrt(5)

Step-by-step explanation:

really ?

this is just using the calculator and see. there is no knowledge or anything else needed.

sqrt(17) = 4.123105626...

so, where does it go ? ... well ? ... right, third position.

sqrt(20) = 4.472135955...

soooo .... ? ... well ... ? ... right, first position.

sqrt(23) = 4.795831523...

aaaaand ... ? ... right, fourth position.

sqrt(19) = 4.358898944...

well, really, there is only one position left : second

Answer: x ≥ [tex]\frac{-2}{5}[/tex]

Step-by-step explanation:

I cannot see what the student did wrong in your question, so I solved for x in the equation...

[tex]5x + 2[/tex] ≥ [tex]x + \frac{2}{5}[/tex]

1. subtract x from both sides

4x + 2 ≥ [tex]\frac{2}{5}[/tex]

2. subtract 2 from both sides to isolate 4x

4x ≥ [tex]\frac{-8}{5}[/tex]

3. divide both sides by 4

x ≥ [tex]\frac{-2}{5}[/tex]

Answer:

x = 3

Step-by-step explanation:

8x + 4 = 28

subtract 4 from both sides

8x + 4 - 4 = 28 - 4

8x = 24

divided both sides by 8

8x / 8 = 24 / 8

x = 3

Answer:

→ 50°

→ Acute triangle

Step-by-step explanation:

the measure of the third angle = 180 - (60 + 70) = 180 - 130 = 50°

definitions=======================================

Acute angle : it’s an angle that measures less than 90°.

Acute triangle: it’s a triangle with three acute angles.

………………………………………………………………………………………………

The measures of the angles in our triangle are respectively 60° , 70° , 50°

Thus ,it’s an acute triangle .

Answer:

1.50x>2.25x+9.00

Step-by-step explanation:

Because the 1.50 has to go their because 2.25 is greater than 1.50, the 9.00 is at the end because their is not a variable. How to know were theh variables go is the each.

She purchased a new lemon squeezer for $9.00.

The cost of the ingredients for each serving of lemonade is $1.50.

She will be selling each serving of lemonade for $2.25.

The inequality that represents the minimum number of servings of lemonade is 1.50x>2.25x+9.00.

We have given that,

Malika is making lemonade to sell at a school fundraiser.

The total cost is the addition of all the costs.

Malika must sell for the money from her sales to exceed the total cost of making the lemonade.

Because the 1.50 has to go there because 2.25 is greater than 1.50, the 9.00 is at the end because there is not a variable.

How to know where variables go is the each.

She purchased a new lemon squeezer for $9.00.

The cost of the ingredients for each serving of lemonade is $1.50.

She will be selling each serving of lemonade for $2.25.

Therefore we get the inequality that represents the minimum number of servings of lemonade is 1.50x>2.25x+9.00.

Answer:

4

Step-by-step explanation:

to find the mean you add up all  of the numbers and then divide by the numbr of numbers there are. So to add them all up that will be 3+5+0+4+7+5+5+3=32

so then you divide 32 by 8 which equals 4.

So therefore your answer is 4.
