Answer 2
Final answer:

To prove ∆ACB ≅ ∆ACD, we use the Reflexive Property, the definition of a midpoint, and the Side-Angle-Side Congruence Postulate, based on the given that C is the midpoint of BD and ∠ACB and ∠ACD are right angles.

Explanation:

To prove that ∆ACB ≅ ∆ACD, given that C is the midpoint of BD in a triangle ABD with a line drawn from A to C creating right angles, we can use the two-column proof format.

Two-Column Proof:AC = AC (Reflexive Property of Equality)C is the midpoint of BD (Given)BC = CD (Definition of Midpoint)∠ACB and ∠ACD are right angles (Given that line AC is perpendicular to line BD)∠ACB ≅ ∠ACD (All right angles are congruent)∆ACB ≅ ∆ACD (Side-Angle-Side Congruence Postulate)

By the Side-Angle-Side postulate, if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

A flagpole is at a ​(3x + 24​)degrees° angle from the ground. Find the value of x.

Answers

The value of x is 22. The angle the flagpole makes with the ground, represented as 3x+24∘, is supplementary to the angle the flagpole makes with the vertical line, which is 90 degrees. By setting up the equation 3x+24° + 90° =180°. and solving for x, we find =22. Thus, the flagpole makes a 3(22) + 24° + 90° =180° angle with the ground.

Certainly, let's break it down step by step:

Given: The angle the flagpole makes with the ground is [tex]\(3x + 24^\circ\).[/tex]

1. **Define the problem**: Let [tex]\( \theta \)[/tex] represent the angle the flagpole makes with the ground.

2. **Write the given information**:

[tex]\[ \theta = 3x + 24^\circ \][/tex]

3. **Understand the geometric situation**: The angle formed by the flagpole with the ground is supplementary to the angle formed by the flagpole with the vertical line

4. **Write the equation based on the supplementary angles relationship**:

[tex]\[ \theta + 90^\circ = 180^\circ \][/tex]

5. **Substitute the given value of [tex]\( \theta \)[/tex]**:

[tex]\[ (3x + 24^\circ) + 90^\circ = 180^\circ \][/tex]

6. **Simplify the equation**:

[tex]\[ 3x + 24^\circ + 90^\circ = 180^\circ \][/tex]

7. **Combine like terms**:

[tex]\[ 3x + 114^\circ = 180^\circ \][/tex]

8. **Isolate \(x\)**:

[tex]\[ 3x = 180^\circ - 114^\circ \][/tex]

[tex]\[ 3x = 66^\circ \][/tex]

[tex]\[ x = \frac{66^\circ}{3} \][/tex]

[tex]\[ x = 22 \][/tex]

[tex]So, \( x = 22 \).[/tex]

Firstly, we can solve for the area of the top rectangle by:

6×4= 24 sq in.

For the next rectangle, we can do:

4×8= 32 sq in.

Finally, the remaining square can be solved by:

It is 85 miles from central city to smithville and 125 miles from smithville to jonesburg. How many gallons of gas will it take to drive from central city to smithville to jonesburg in a car which gets 30 miles per gallon?

Answers

It will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

To calculate the total amount of gas needed to drive from Central City to Smithville to Jonesburg, we need to add up the distances for each leg of the trip and then divide by the car's mileage per gallon.

Central City to Smithville: 85 miles

Smithville to Jonesburg: 125 miles

Total distance: 85 + 125 = 210 miles

Given the car gets 30 miles per gallon, divide total distance by mileage per gallon:

Total gallons of gas needed = 210 miles ÷ 30 MPG = 7 gallons

Therefore, it will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

Answers

Answer:

Length = 13

Width = 9

Step-by-step explanation:

The equation to find the perimeter is 2l+2w=44. The second equation is 2w-5=l since the length is 5 less than double the width.

2l+2w=44,2w-5=l (write equations)

use the equation for length, the second equation, and subtitute it into the first equation's l. Since all l is the same and 2w-5 is equal to l, we can use that equation for the l in 2l+2w=p

2(2w-5)+2w=44 (subtitute)

4w-10+2w=44

6w-10=44 (simplify)

6w=54 (add 10 to both sides)

w=9

use the width to find the length by plugging it into any original equation

2w-5=l

2(9)-5=l

18-5=l

13=l

Answer:

The length is 13.

The width is 9.

Step-by-step explanation:

length = x

width = w

1) x = 2w - 5

2) 44 = 2x + 2w

3) 44 = 2(2w - 5) + 2w

4) 44 = 4w - 10 + 2w

5) 44 = 6w - 10

6) 54 = 6w

7) w = 9

8) x = 2(9) - 5

9) x = 18 - 5

10) x = 13

equation of this parallel line?

Answers

Answer:

For this case since we want a parallel line to -2x+1 we need the same slope so then m = -2 and we have:

[tex] y =-2 x+b[/tex]

Now we can find the intercept b with the condition given x= 4 , y=1 and we got:

[tex] 1 = -2*4 +b[/tex]

And solving for b we got:

[tex] b = 1+8 = 9[/tex]

And our equation would be:

[tex] y = -2x +9[/tex]

Step-by-step explanation:

For this case we need to find an equation for a line who is parallel to y = -2x + 1 and  intersects the point (4,1)

The general equation for a line is given by:

[tex] y = mx +b[/tex]

For this case since we want a parallel line to -2x+1 we need the same slope so then m = -2 and we have:

[tex] y =-2 x+b[/tex]

Now we can find the intercept b with the condition given x= 4 , y=1 and we got:

 Alexander is a stockbroker. He earns 13​% commission each week. Last​ week, he sold ​$4 comma 500 worth of stocks. How much did he make last week in​ commission? If he averages that same amount each​ week, how much did he make in commission in​ 2011?

Answers

Multiply the amount he sold by the percent of commission:

4500 x 0.13 = 585

he made $585 last week.

There are 52 weeks in a year, multiply the amount of commission by 52:

585 x 52 = 30,420

he made $30,420 in 2011.

Final answer:

Alexander made $585 in commission last week. In 2011, he made $30,420 in commission.

Explanation:

To calculate Alexander's commission, we can multiply the value of the stocks he sold by the commission rate.

$4,500  imes 0.13 = $585

Therefore, Alexander made $585 in commission last week.

To calculate how much he made in commission in 2011, we need to know the number of weeks in 2011. Assuming there are 52 weeks in a year, we can multiply Alexander's weekly commission by the number of weeks in 2011:

$585  imes 52 = $30,420

A used car dealer sells SUVs and cars. Of all the vehicles, 90% are cars. Of all the vehicles 40% are red cars. What is the probability that a car chosen at random is red? Round your answer to the nearest tenth of a percent.

Answers

Answer:

44.4%

Step-by-step explanation:

To calculate this, we proceed as follows.

we use the probability equation below;

P(A|B) = P(A and B) / P(B)

Applying the above to the scenario at hand;

P(red | car) = P(red and car) / P(car)

P(red and car) = 40% or simply 40/100 = 0.4

P(car) = 90% = 90/100 = 0.9

P(red | car) = 0.4/0.9

P(red | car) = 0.4444 which is = 44.44% ; to the nearest tenth of a percent = 44.4%

Final answer:

To find the probability of a randomly chosen car being red, you divide the percentage of red cars by the percentage of all cars. The calculation results in 44.4%, which is the probability that a car is red.

Explanation:

To find the probability that a car chosen at random is red, we use the information provided: 90% of all vehicles are cars, and 40% of all vehicles are red cars. To determine the probability of a randomly selected car being red, we must calculate the percentage of red cars within the group of all cars.

This is done by dividing the percentage of red cars by the percentage of all cars, which gives us the probability that a car, given it's a car, is red.

The calculation is (40% / 90%) × 100, which simplifies to 44.4%. Rounded to the nearest tenth of a percent, the probability is 44.4%.

Step-by-step explanation:

The triangular end of the tent has a base of 3 ft and a height of 2 ft. Its area can be found using the formula for the area of a triangle:

  A = (1/2)bh

  A = (1/2)(3 ft)(2 ft) = 3 ft^2

__

The rectangular side of the tent has a length of 4 ft and a width of 2.5 ft. Its area can be found using the formula for the area of a rectangle:

  A = lw

  A = (4 ft)(2.5 ft) = 10 ft^2

___

If we assume the tentmaker makes the two sides not shown exactly the same as these, then the total above-ground material will be ...

  2(3 ft^2 +10 ft^2) = 26 ft^2

If there is on-ground material (a floor), that rectangle adds (3 ft)(4 ft) = 12 ft^2 to the total.

The area of the tent above-ground is 26 square feet. With a floor, it is 38 square feet.
