Answer:

41°

Step-by-step explanation:

180°- 63° - 76° = 41°

Given:

Parallel lines p and q are cut by transversal r.

m∠3=(3x + 4)° and m∠5=(2x + 11)°.

To find:

The relation between ∠3 and ∠5, then find the measure of angle 5.

Solution:

Parallel lines p and q are cut by transversal r as shown in the below figure.

From the figure it is clear that ∠3 and ∠5 are alternate interior angle. So, the values of these angles are equal.

[tex]m\angle 3=m\angle 5[/tex]

[tex](3x+4)^\circ=(2x+11)^\circ[/tex]

[tex]3x+4=2x+11[/tex]

Therefore, the required equation to solve for x is [tex]3x+4=2x+11[/tex].

Isolate variable terms.

[tex]3x-2x=11-4[/tex]

[tex]x=7[/tex]

The value of x is 7.

Now,

[tex]\angle 5=(2x+11)^\circ[/tex]

[tex]\angle 5=(2(7)+11)^\circ[/tex]

[tex]\angle 5=(14+11)^\circ[/tex]

[tex]\angle 5=25^\circ[/tex]

Therefore, the measure of angle 5 is 25°.

Answer:

The neighbor is 20 years old.

The third neighbor is 68 years old.

Step-by-step explanation:

Equations

Let's set:

x=current age of the neighbor

x+5=his age in 5 years

x-5=his age 5 years ago

He claims that his age is the difference between twice his age in 5 years and twice his age 5 years ago. Then:

x = 2( x + 5 ) - 2( x - 5 )

Operating:

x = 2x + 10 - 2x +10

Simplifying:

x = 20

The neighbor is 20 years old.

Repeating for the other neighbor, a similar equation is established:

x = 2( x + 17 ) - 2( x - 17 )

Operating:

x = 2x + 34 - 2x +34

Simplifying:

x = 68

The third neighbor is 68 years old.

Answer:

2 1/7

Step-by-step explanation:

Answer:

2 1/7, is 15/7(improper fraction) as a mixed fraction, and

1 8/7 is an improper mixed fraction equivilent to 2 1/7.

Step-by-step explanation:

15/7 = 7/7 + 7/7 + 1/7 = 1 + 1 + 1/7 = 2 1/7

1 8/7 = 1 + 8/7 = 1 +7/7 + 1/7 = 1 + 1 + 1/7 = 2 1/7

Answer:

$675

Step-by-step explanation:

You multiply 15 and 100 answer for that is 1500 then you multiply 21.75 and 100 answer for that is 2175 finally you subtract 1500 from 2175 witch gives you the final answer of 675

Total profit from the sale of 100 shares is equals to $675.

" Profit is the amount of money or revenue which we earned when  selling price of a product is more than its cost price."

Formula used

Profit = Selling price - Cost price

According to the question,

Cost price  of 1 share = $15

Therefore,

Cost price of 100 shares = 15 × 100

                                         = $1500

Selling price of 1 share = $21.75

Selling price of 100 shares = 21.75 ×100

                                            = $2175

Selling price > Cost price

Therefore , Profit

Substitute the value in the formula we get,

Profit = 2175 - 1500

         = $675

Hence, total profit from the sale of 100 shares is equals to $675.

The statement is false 4 is not bigger than 19.

Answer:

equation: y=-7.5x+15 and Raul must ride at a speed of 5 mi/hr

Step-by-step explanation:

[tex]\frac{y2-y1}{x2-x1}[/tex] to find out the slope. [tex]\frac{6-11.25}{1.2-0.5}[/tex]=[tex]\frac{-5.25}{0.7} = -7.5[/tex]

Then you fill x and y to find out the y intercept

[tex]11.25=-7.5*0.5+b[/tex]

[tex]11.25=-3.75+b\\11.25+3.75=15\\[/tex]

Y intercept= 15

then you put it in the equation:

y=-7.5x+15

Since Raul lives 5 miles closer and Luis is 5 miles away, he needs to go at 5 miles an hour to get to the spot.

That is 5 miles/hour

The distance and time, as presented in this question are illustrations of linear equations.

From the diagram, we have:

[tex](x_1,y_1) = (0.5,11.25)[/tex]

[tex](x_2,y_2) = (1.2,6)[/tex]

Start by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{6 - 11.25}{1.2 - 0.5}[/tex]

[tex]m = \frac{-5.25}{0.7}[/tex]

[tex]m = -7.5[/tex]

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives

[tex]y = -7.5(x - 0.5) + 11.25[/tex]

[tex]y = -7.5x + 3.75 + 11.25[/tex]

[tex]y = -7.5x + 15[/tex]

Calculate distance, when [tex]x = 5[/tex]

We have:

[tex]y = -7.5 \times 5 + 15[/tex]

[tex]y = -22.5[/tex]

The speed (s) is then calculated as:

[tex]s = \frac{22.5}{5}[/tex]

[tex]s = 4.5[/tex]

Hence, he must plan to ride at 4.5 miles per hour

Answer:

The arrow will take 4.19 seconds to hit the ground

The arrow will go 24 feet to reach its maximum height and it takes 2 seconds to reach this height

Step-by-step explanation:

The quadratic function is f(t) = -5t² + 20t + 4, where

f(t) is the height in feet

t is the time in seconds

If the arrow hit the ground that means h(t) = 0

→ Substitute h(t) by 0 and use the quadratic formula to find t

∵ h(t) = 0

∴ 0 = -5t² + 20t + 4

→ Switch the two sides

∴ -5t² + 20t + 4 = 0

→ Multiply all terms by -1 to make the coefficient of t² positive

∴ 5t² - 20t - 4 = 0

→ The quadratic formula is [tex]t=\frac{-b+-\sqrt{b^{2}-4ac}}{2a}[/tex] , where

∵ a = 5, b = -20, c = -4

∴ [tex]t=\frac{-5+-\sqrt{(-20)^{2}-4(5)(-4)}}{2(5)}[/tex]

∴ [tex]t=\frac{-5+-\sqrt{400+80}}{10}[/tex]

→ Find the values of t in decimal

∴ t = 4.19 seconds OR t = -0.19 ⇒ refused because it is negative

∴ The arrow will take 4.19 seconds to hit the ground

The graph of this quadratic function is a parabola with maximum vertex (h, k), where

To find the maximum height and the time taking for this to occur find h and k where k is the maximum height and h is the time for this to occur

∵ f(t) = -5t² + 20t + 4

∵ a = -5 and b = 20

∴ h = [tex]-\frac{20}{2(-5)}=-\frac{20}{-10}=2[/tex]

∴ The time for the maximum height is 2 seconds

→ Now use it to find k

∵ k = f(h)

∴ k = f(2)

∵ f(2) = -5(2)²+ 20(2) + 4

∴ f(2) = -5(4) + 40 + 4

∴ f(2) = -20 + 40 + 4

∴ f(2) = 24

∴ k = 24

∴ The maximum height is 24 feet

The arrow will go 24 feet to reach its maximum height and it takes 2 seconds to reach this height
