Answer:

1. Reflect ABC about the line AC and then translate 1 unit to the right.

2. Translate ABC 1 unit to the right and then reflect it about the line AC.

Step-by-step explanation:

We are given that,

ABC is transformed using glide reflection to map onto DEF.

Since, we know,

'Glide Reflection' is the transformation involving translation and reflection.

So, we can see that,

ABC can be mapped onto DEF by any of the following glide reflections:

1. Reflect ABC about the line AC and then translate 1 unit to the right.

2. Translate ABC 1 unit to the right and then reflect it about the line AC.

Hence, any of the two glide reflection will map ABC onto DEF.

50 men working 10 hours daily can complete a job in

Sliva [168]

<h2>Given :-</h2>

50 men do 10 hours work daily complete work in 20 days

80 men do job in 50% time

Days required

<h2>Solution :-</h2>

1 man may do job in (50 × 20) days =
1 man may do job in 1000 days

Now,

80 man = 1000/80 = 12.5

Now,

When hours reduced 50% then we will multiply days by 2
Total days = 12.5 × 2 = 25 days.

<h2>Hence</h2>

Option C is correct

Answer:

The answer is 117.3 $in^{3}$ .

Step-by-step explanation:

To solve for the volume of the cone, use the cone volume formula, which is V = $\frac{1}{3} \pi r^{2} h$ .

Next, plug in the information given from the problem, and the formula will look like V = $\frac{1}{3} (\pi) (4 in^{2}) (7 in)$ .

Then, solve the equation, and the answer will be 117.3 $in^{3}$ .

A sidewalk around a circular park covers a distance of 65 meters. A new sidewalk is being constructed across the park through it

lidiya [134]

All we have to do is divide the distance of the old sidewalk by 3.14:

65 / 3.14 ≈ 20.7006

That means that, rounded to the nearest meter, the new sidewalk is:

21 meters long!

Is (a-3)(2a^2 + 3a + 3) equivalent to 2(a^3 - 1.5a^2 - 3a - 4.5)

vovikov84 [41]

<h3>Answer: Yes they are equivalent</h3>

==============================================

Work Shown:

Expand out the first expression to get

(a-3)(2a^2 + 3a + 3)

a(2a^2 + 3a + 3) - 3(2a^2 + 3a + 3)

2a^3 + 3a^2 + 3a - 6a^2 - 9a - 9

2a^3 + (3a^2-6a^2) + (3a-9a) - 9

2a^3 - 3a^2 - 6a - 9

Divide every term by 2 so we can pull out a 2 through the distributive property

2a^3 - 3a^2 - 6a - 9 = 2(a^3 - 1.5a^2 - 3a - 4.5)

This shows that (a-3)(2a^2 + 3a + 3) is equivalent to 2(a^3 - 1.5a^2 - 3a - 4.5)
