Answer:

  A)  The number of hours spent painting each house

Step-by-step explanation:

You know that the cost of painting will include the product of the hourly cost (55 or 25) and the number of hours.

The equations have x multiplied by 55 or 25, so it is reasonable to assume that ...

  x represents the number of hours spent painting

2y + 1 - x = 7x

2y + 1 = 8x

2y = 8x - 1

y = 4x - 1/2

Answer:

X = 3x + 3

And

X = 4/3y + 4

Answer:

-3

Step-by-step explanation:

3*-3=-9

-9-20=-29

To find the number, we can represent it as 'x' and create an equation. By isolating 'x' using addition and division, we find that the number is -3.

To solve this problem, let's represent the number as 'x'. The product of 3 and the number can be written as 3x. According to the problem, 20 less than 3x is equal to -29.

We can write this as: 3x - 20 = -29. To find the value of x, we need to isolate x. Adding 20 to both sides of the equation, we get: 3x = -9.

Finally, dividing both sides by 3, we find that the number is x = -3.

Answer:

D. 5.0

Step-by-step explanation:

When the ball hit the ground, height h =0

So,

h= -4.9t² + 25t

0 = -4.9t² +25t

t(-4.9t+25)=0

t=0 (start) , and -4.9t+25=0,   4.9t =25,    t≈5.1(finish)

Answer:

not sure about 1

for number 2 it is 5 over 4 . for y, 5 10 15 20 is a multiple of 5 so the change is 5. for x, 4 8 12 16 is a multiple of 4 so the change is 4.

That is Correct ^^^^

The given measures of AB, AOB, and BDA are correct angles,

AB= 50°

AOB= 50°

BDA=25°

First, notice that angle AOB is an inscribed angle that intercepts arc AB, which means its measure is half of the measure of arc AB. Therefore, to find the measure of angle AOB, we just need to divide the measure of arc AB by 2:

arc AB = 360° - arc AD - arc BD = 360° - 212° - 98° = 50°

∠AOB = arc AB / 2 = 50° / 2 = 25°

Next, angle BDA is an angle formed by a tangent and a chord that intersects the tangent at the point of tangency. This means that angle BDA is equal in measure to half of the measure of the intercepted arc BD. Therefore, we just need to divide the measure of arc BD by 2 to find the measure of angle BDA:

∠BDA = arc BD / 2 = 98° / 2 = 49°

So far, we have found that AB = 50°, AOB = 25°, and BDA = 49°.

Finally, to check our work, we can use the fact that angles AOB and BDA are vertical angles, which means they are equal in measure. Therefore, we can add their measures and compare the result to the measure of angle AOD:

∠AOD = 180° - arc AD = 180° - 212° = -32° (counterclockwise)

∠AOB + ∠BDA = 25° + 49° = 74°

Since the sum of angles AOB and BDA is less than 180°, we know that angle AOD must be greater than 180°, which means we need to add 360° to its measure to get its actual measure:

∠AOD = -32° + 360° = 328° (clockwise)

Now we can check that angle AOB + angle BDA = angle AOD:

25° + 49° = 74° = 328° (mod 360°)

So our values for AB, AOB, and BDA are correct.

100°

Step-by-step explanation:

AB = AC (given)

Therefore, ∆ ABC is an isosceles triangle.

m<B=m< C= 40°

sum of the interior angles of a triangle= 180°

m<A+40°+40°=180°

m<A = 180°-80° = 100°

Answer:

< A is 100

Step-by-step explanation:

<B is 40 <C is also 40

so 40+40= 80 then you have to do 180-80. Which equals 100.

The answer is shown in the picture☝️.

Formula :

cos(π/2 - x) = sin x

cos(π - x) = -cos x

cos²x + sin²x = 1

loga(b) + loga(c) = loga(b×c)

Steps to solve:

5 - 5cos(π/2 - x) = 2cos²(π - x)

~Use an identity to simplify cos(π/2 - x)

cos(π/2 - x) → sin(x)

~Use an identity to simplify cos(π - x)

cos(π - x) → -cos(x)

~Put back into an expression

5 - 5sin(x) = 2(-cos(x))²

~Simplify

5 - 5sin(x) = 2cos²(x)

~Subtract 2cos²(x) to both sides

5 - 5sin(x) - 2cos²(x) = 2cos²(x) - 2cos²(x)

~Simplify

5 - 5sin(x) - 2cos²(x) = 0

~Use an identity to simplify

5 - (1 - sin²(x)) * 2 - 5sin(x) = 0

~Simplify

3 + 2sin²(x) - 5sin(x) = 0

~Let sin(x) = u

3 + 2u² - 5u = 0

~Use the quadratic formula to solve for u.

[tex]x=\frac{-(-5)+-\sqrt{(-5)^2-4(2)(3)} }{2(2)}[/tex]

[tex]u = \frac{3}{2}, u=1[/tex]

~Substitute back with sin(x) = u

sin(x) = 3/2 or sin(x) = 1

Steps to solve:

log₂(1 - x) + log₂(-5x - 2) = 2 + log₂3

~Apply log rule

log₂((1 - x(-5x - 2)) = 2^2+(log₂(3)

~Use log definition

(1 - x)(-5x - 2) = 2^2+log₂(3)

~Expand both sides

5x² - 3x - 2 = 12

~Subtract 12 to both sides

5x² - 3x - 2 - 12 = 12 - 12

~Simplify

5x² - 3x - 14 = 0

~Use the quadratic formula to solve

[tex]x = \frac{-(-3)+-\sqrt{(-3)^2-4(5)(-14)} }{2(5)}[/tex]

~Simplify

x = 2 or x = -7/5

Answer:

log(18/(p+2))

log StartFraction 18 Over p + 2 EndFraction

Second option is the correct.

Step-by-step explanation:

There is a property of logarithms that when two logarithms are subtracting each other, we can make a single logarithm with the argument being the division of their arguments:

log(x) - log(y) = log(x/y)

So, with we have log18 – log(p + 2), we can rewrite as:

log18 – log(p + 2) = log(18/(p+2)), that is:

log StartFraction 18 Over p + 2 EndFraction

Second option is the correct.

The base of the ladder needs to be positioned approximately 27.3 feet away from the wall.

Let's consider the ladder as the hypotenuse of a right triangle, where one leg represents the distance from the building (let's call it 'x'), and the other leg is the height of the window above the ground (10 feet). The angle between the ground and the ladder is given as 68°.

We can use the tangent function, which is defined as the ratio of the opposite side (height of the window) to the adjacent side (distance from the building):

tan(θ) = Opposite / Adjacent

In this case, tan(68°) = 10 feet / x

To find 'x,' we can rearrange the equation:

x = 10 feet / tan(68°)

Now, we can plug the values into a calculator to get the answer:

x ≈ 27.3 feet
