30 tickets

Step by step:
When you multiply 30x8 you get 240. You multiply by 8 because that is how much one adult ticket costs. And they tell you that they sold a total of 70 tickets, which means to find the number of children tickets that were sold would be 70-30=40. Then to prove that for sure, multiply...

40x5=200. You multiply by 5 because that is how much one children ticket costs.

Then when you add the totals of the adult tickets sold and the children tickets sold, you get $440, which means that 30 adult tickets were sold!!

You can use this same process for problems like these or to verify the answer!

Please give me brainliest!
Hope this helped!

Drag the ordered pair that are 5.5 units apart.

Alexus [3.1K]

Answer:

(-1.5, -3.5) and (-1.5, 2)

Step-by-step explanation:

The x-coordinates in increasing order are ...

-3, -1.5, 5

The distances between pairs of these coordinates are ...

-1.5 -(-3) = 1.5

5 -(-3) = 8

5 -(-1.5) = 6.5

Clearly, any pair with x = 5 is too far away from any pair with a different x-value.

If the distance between pairs is 5.5, then the distance formula tells us the y-coordinate differences for pairs with x-coordinates of -3 and -1.5 must be ...

d = √((x2 -x1)^2 +(y2 -y1)^2)

5.5 = √(1.5^2 +(y2 -y1)^2) . . . substitute known values

30.25 = 2.25 +(y2 -y1)^2 . . . . square both sides

√28 = (y2 -y1) . . . . . . . . . . . . . . subtract 2.25 and take the square root

This value is irrational. Clearly none of the y-coordinates is irrational, so there are no point pairs with x-coordinates -3 and -1.5 that are 5.5 units apart.

If the x-coordinates are the same, then the y-coordinates must differ by 5.5 in order for the points to be 5.5 units apart. The coordinates in order are ...

for x = -1.5, y = -3.5, 2, 2.5 . . . . . differences of 5.5, 6, 0.25

for x = 5, y = -3.5, 1.5 . . . . . . . difference of 5

The only pair we can find that is 5.5 units apart is ...

(-1.5, -3.5) and (-1.5, 2).

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen

Vlad [161]

The simultaneous equations are
2x - 7y = 4 (1)
3x + y = -17 (2)

Write (2) as
y = - 3x - 17 (3)

Substitute (3) into (1).
2x - 7(-3x - 17) = 4
2x + 21x + 119 = 4
23x = -115
x = -5
This is the equation obtained after substituting y from the second equation into the first equation.
The solution for y is
y = -3(-5) - 17 = -2

Answer: x = -5

Note: The solution is x = -5, y = -2.

Which equation can be used to find the measure of angle gfe? cos−1(startfraction 14.5 over 11.9 endfraction) = θ cos−1(startfrac

The equation that can be used to find the measure of angle GFE is given by: Option B: cos−1(11.9/14.5) = θ

<h3>What are the six trigonometric ratios?</h3>

Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.

In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slant side is called hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

From that angle (suppose its measure is θ),

$\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\$

The missing information, not present in this question are:

Length of FG = |FG| = 14.5
Length of FE = |FE| = 11.9
Angle ∠GFE = θ

Since for the triangle GFE, if we look from the angle ∠GFE, the sides given are hypotenuse FG and the base FE.

Thus, we can use cosine ratio, and then its inverse to find the value of angle θ.

Thus, we get:

$\cos(\theta) = \dfrac{|FE|}{|FG|} = \dfrac{11.9}{14.5} \\\\\theta = \cos^{-1}\left(\dfrac{11.9}{14.5}\right)\\\\$

Thus, the equation that can be used to find the measure of angle GFE is given by: Option B: cos−1(11.9/14.5) = θ

Help me pleaseeeeeeeeee

Karo-lina-s [1.5K]

It has to be B. (0,4) because it does not satisfy the 2nd equation. There would have to be an equal sign because both sides would be 4 but there is none, so B. is your answer.
