Answer:
x = 39.1
Step-by-step explanation:
mean = average off all the numbers =
sum of the numbers / amount of numbers.
35 = sum of the #'s / # of #'s
35 = 100.9 + x / 4
35 × 4 = 100.9 + x / 4 × 4
140 = 100.9 + x
140 – 100.9 = 100.9 + x – 100.9
39.1 = x
x = 39.1

find the length of EF in this Pythagorean theorem problem and show work please and thanks you
Answer:
I'm not sure if you can solve this with Pythagorean Theorem because as far as I know, you need sides not angle+side combination. Despite this, let's solve this one using sine law, cosine law or even tangent.
Step-by-step explanation:
[tex] \tan(61) = \frac{length \: of \: df}{24} \\ length \: of \: df = 24 \tan(61) \\ = 43.2971 \\ \\ \cos(19) = \frac{length \: of \: df}{length \: of \: ef} \\ length \: of \: ef \: = \frac{43.2971}{ \cos(19) } \\ = 45.7919[/tex]
Asanji left the science museum and drove toward the lake at an average speed of 45 km/h. Sometime later Huong left driving in the same direction but at an average speed of 75 km/h. After driving for three hours Huong caught up with Asanji. How long did Asanji drive before Huong caught up?
Answer:
Asanji drove for [tex]5[/tex] hours before Huong caught up
Step-by-step explanation:
Let the time for which Asanji drove alone is "X" hours
Asanji and Huong met after three hours of driving of Huong.
Total time for which Asanji drove [tex]= X+3[/tex] hours
Thus, distance travelled by Asanji in [tex]X+3[/tex] hours is equal to distance travelled by Huong in [tex]3[/tex] hours
[tex]45 ( X+3) = 75 (3)\\[/tex]
On solving the above equation, we get -
[tex]45 X + (45 *3) = 75 *3\\45 X = (75-45)*3\\45 X = 30 *3 \\X = \frac{30 *3}{45} \\X = 2[/tex]
Asanji drove for [tex]3 + 2 = 5[/tex] hours before Huong caught up
Solve for X and Y

Answer:
x = 7
y = 3
Step-by-step explanation:
[tex]\triangle ABC[/tex] is an equilateral triangle so that means all sides are equal
which means
[tex]AB= BC=AC\\\\7=x[/tex]
now in [tex]\triangle ACD[/tex] is an isosceles triangle so that means opposite sides to the angles that have the same measure are equal
which means
[tex]AC=CD\\\\AC = y+4[/tex]
now remember that AC is a side of the equilateral [tex]\triangle ABC[/tex] so AC = 7
solving for y
[tex]7=y+4\\\\7-4 = y\\\\3=y[/tex]
so
[tex]x = 7\\\\y = 3[/tex]

The value of the dependent variable y is always four times(one fourth or four times) the value of the independent variable x. Show me how.
Pls help
Answer:
y=4x
Step-by-step explanation:
when x is 1 the y value is 4. this means each times x moves 1 across the x axis, the y value will go up 4 on the y axis. this means the equation has a slope of 4

The measure of an angle is 32.9°. What is the measure of its complementary angle?
Answer: 57.1
Step-by-step explanation: To be complementary the angles have to add up to make a sum of 90.
90 - 32.9 = 57.1
The angles are 32.9 and 57.1.

Answer:
reflection across y-axis
Step-by-step explanation:
the shape flipped over vertically (y axis) and not horizontally (x axis), so it reflected across the y-axis and not the x-axis
Answer:
The answer is D) Reflection across y-axis.
Step-by-step explanation:
You can tell by looking at the labeled points that the shape was reflected that it was reflected across the y-axis. Think of it like a mirror: the image flipped across the y-axis, so we know that is the right answer.
A gardener will use up to 240 square feet for planting flowers and vegetables. She wants the area used for vegetables to be at least four times the area used for flowers. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and y that satisfy these requirements.

Answer:
x = 12
Step-by-step explanation:
The ray from the vertex to the base is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{x}{9}[/tex] = [tex]\frac{4}{3}[/tex] ( cross- multiply )
3x = 36 ( divide both sides by 3 )
x = 12

Debbie bought a computer for 25% off the list price. If the list price is $2,428, how much did Debbie spend?
Given:
Debbie bought a computer for 25% off the list price.
The list price = $2,428
To find:
The amount spend by Debbie.
Solution:
We have,
The list price = $2,428
Money spend by Debbie = List price - 25% of list price
[tex]=2428-\dfrac{25}{100}(2428)[/tex]
[tex]=2428-607[/tex]
[tex]=1821[/tex]
Therefore, the amount spend by Debbie is $1821.

Express -5x(x+6) = 4(x-3)-10 in the form ax^2+bx+c=0 (quadratic formula)
Answer:
[tex]5x^{2} + 34x - 22[/tex]
Step-by-step explanation:
-5x ( x + 6 ) = 4 ( x - 3 ) - 10
Distribute
[tex]-5x^{2} - 30x = 4x - 12 - 10[/tex]
Simplify,
[tex]-5x^{2} -30x = 4x -22[/tex]
Inverse operations;
[tex]-5x^{2} - 30x = 4x - 22\\ +30x +30x\\\\-5x^{2} = 34x - 22\\+5x^{2} +5x^{2}\\\\5x^{2} + 34x - 22[/tex]
Answer:
5x^2 + 34x - 22 = 0
Step-by-step explanation:
-5x(x+6) = 4(x-3)-10
-5x^2 - 30x = 4x - 12- 10
-5x^2 - 30x - 4x + 22 = 0
-5x^2 - 34x + 22 = 0
5x^2 + 34x - 22 = 0
Which quadratic equation is equivalent to (x – 4)2 – (x – 4) – 6 = 0?
Answer:
Step-by-step explanation:
Posible answers are found
if you square (x-4), open pharenthesis -(x-4) and then combine like terms
x^2 +16-8x -x+4-6 =0
x^2 -9x +14 =0
or you can substitute (x-4) with another letter like x-4 =a so
a^2 -a -6 =0
