-5x + 12 - 7x = -3(5x + 8)
Answer:
x = -12
Step-by-step explanation:
-5x + 12 - 7x = -3(5x + 8)
-5x + 12 - 7x = -15x - 24
-12x + 12 = -15x - 24
-12x + 15x = -24 - 12
3x = -36
x = -12

Answer:
sinθ = [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
= (24)² + 7²
Hypotenuse = √625 = 25
By applying sine rule in the given triangle,
sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
Since, measure of opposite side = 24
Measure of hypotenuse = 25
Therefore, sinθ = [tex]\frac{24}{25}[/tex] will be the answer.

Answer:

Step-by-step explanation:
The location of point G which partitions the directed line segment from D to F into a 5:4 ratio is; x = 3
Division of a Line Segment
The formula for coordinate of a point that divides a line segment in a ration is given by;
x = (mx₂ + nx₁)/(m + n)
We are given the ratio 5:4
Thus m = 5 and n = 4
The endpoints of DF are D(-2) and F(7)
Thus;
x = ((5*7) + 4(-2))/(5 + 4)
x = 27/9
x = 3
Thus, the location of point G which partitions the directed line segment from D to F into a 5:4 ratio is x = 3

A, B & C form a triangle where ∠ BAC = 90°. AB = 6 mm and CA = 7.3 mm. Find the length of BC, giving your answer rounded to 1 DP.
Answer:
BC ≈ 9.5 mm
Step-by-step explanation:
Since, ΔBAC is a right angle triangle,
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = AB² + AC²
BC² = 6² + (7.3)²
BC = [tex]\sqrt{89.29}[/tex]
BC =
BC = 9.445
BC ≈ 9.5 mm
BRAINLIEST and HELP!!!! A worker is connecting a cable from the rooftop of a school to a fence pole 7 ft away. The pole is 10 ft high. He uses 25 ft of cable to reach from the rooftop to the fence pole. How tall is the school?
(NOBODY ANSWER IF YOU DONT HAVE IT!!)
Answer:
yee its 34ft..........
Height of the school building is equals to 34ft.
What is height?
" Height is defined as one of the dimension which represents the distance between base and the top."
Formula used
Pythagoras theorem
(Hypotenuse)² = (Opposite side)² + (adjacent side)²
According to the question,
'h+ 10 ' represents the height of the building
As shown in the figure,
In the right triangle
' Hypotenuse' represented by length of the cable = 25ft
Adjacent side = 7ft
'h' is the height of the triangle
Substitute the value in the Pythagoras theorem we get,
[tex](25)^{2} = 7^{2} + h^{2}[/tex]
⇒ [tex]h^{2} = 625 - 49[/tex]
⇒ [tex]h = \sqrt{576}[/tex]
⇒ [tex]h = 24[/tex] ft.
Therefore,
Height of the school building [tex]' h + 10 '= 24 + 10[/tex]
[tex]= 34[/tex] ft.
Hence, height of the school building is equals to 34ft.

The average life expectancy of people in the united states in 2018 was 78.54 years with a standard deviation of approximately 15 years
Question:
The average life expectancy of people in the United States in 2018 was 78.54 years with a standard deviation of approximately 15 years.
Suppose we take a sample of 40 individuals in the United States, what are the mean and standard deviation for sample averages from samples of size 40?
Answer:
[tex]\bar x = 78.54[/tex]
[tex]\sigma_x = 2.37[/tex]
Step-by-step explanation:
Given
[tex]\mu = 78.54[/tex] --- Population mean
[tex]\sigma = 15[/tex] --- Population standard deviation
[tex]n = 40[/tex] --- Sample size
Solving (a): The sample mean
According to the central limit theorem, sample mean is always equal to the population mean.
So:
[tex]\bar x = 78.54[/tex]
Solving (b): The sample standard deviation
Using the central limit theorem, we have:
[tex]\sigma_x = \frac{\sigma}{\sqrt n}[/tex]
So:
[tex]\sigma_x = \frac{15}{\sqrt{40}}[/tex]
[tex]\sigma_x = \frac{15}{6.32}[/tex]
[tex]\sigma_x = 2.37[/tex]

In 1979, the price of electricity was $0.05 per kilowatt-hour. The price of electricity has increased at a rate of approximately 2.05% annually. If t is the number of years after 1979, create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10. Fill in the values of A, b, and c for this situation. Do not include dollar signs in the response.
c=A(b)^x
The equation that can be used to determine the number of years it would take for the price to be $0.10 is 0.10 = 0.05(1.0205)^t.
What is the equation that models the increase?
The equation that would be used is an exponential equation. An exponential equation is used because the rate of increase is a compound growth.
Exponential equations usually have this form: FV = PV( 1 + r)^t
Where:
FV = future value PV = present value r = rate of growth t = time0.10 = 0.05(1.0205)^t.
