A 120-ft long is just 15in on the scale drawing. What is the scale on the scale drawing?

Answers

Answer 1
Answer: 120/15=8.

What that means is that for every 8 feet, there's 1 inch added to the scale drawing. Good luck!

What is the area of the trapezoid? A trapezoid has a base of 20 feet, a height of 24 feet, and a top side length of 16 feet.

Answers

the area of the trapezoid is 432 ft2

Answer:

EASY PEASY!

Step-by-step explanation:

So First, We have to create an equation that can find the area!

Using the area of a trap. formula:

A=((b_(1)+b_(2) ) )/(2) \left * h\n

A=(16+20)/(2) *24\nA=18*24\nA=432

The area of the trapezoid is 432 ft^2

There you go!

Hope this helps!

Cereal costs $2.79 for 16.4 ounces. At this rate how much does 25 ounces of cereal cost?

Answers

First let find the unit rate which is how much will one ounce cost?
To find the unit rate you have to divide 2.79 divided by 16.4 which gives you .17 .
For ever ouce you buy its going to cost you 17 cents.
you are trying to find how much 25 ounces cost so multiply 25x.17
And you get a result of 4 dollars, the answer is $4







Final answer:

To find the cost of 25 ounces of cereal, set up a proportion using the given information and solve for the unknown cost.

Explanation:

To find the cost of 25 ounces of cereal, we can set up a proportion using the given information. The cost of 16.4 ounces of cereal is $2.79. We can set up the proportion as:

16.4 ounces / $2.79 = 25 ounces / x (unknown cost)

Cross multiplying, we get:

16.4x = 2.79 * 25

Solving for x, we find the cost of 25 ounces of cereal to be approximately $4.76.

What is the reciprocal of 2 3/8

Answers


Hey there! Let me help you!

To find what the reciprocal is, you have to turn a proper fraction upside down. For example, the reciprocal of 2/8 would be 8/2. However, when you have an improper fraction, you must first turn it into an improper fraction. To turn a mixed number into an improper fraction, multiply the denominator by the whole number and add the numerator. The denominator will stay the same. For example, to turn 2 3/8 into an improper fraction, multiply 8 by 2 and add 3. That equals to 19. The denominator will stay the same. So, the improper fraction for 2 3/8 is 19/8. Now, turn 19/8 into a reciprocal. 19/8 as a reciprocal would be 8/19.

Thank you!

The reciprocal of fraction 2(3/8) is 8/19.

We have,

To find the reciprocal of a number, we invert the fraction by swapping the numerator and denominator.

Given the number 2 3/8, we first convert it to an improperfraction:

2 3/8 = (2 * 8 + 3) / 8 = 19/8

To find the reciprocal, we invert the fraction by swapping the numerator and denominator:

Reciprocal = 8/19

Therefore,

The reciprocal of fraction 2(3/8) is 8/19.

Which transformations will produce similar, but not congruent, figures?Choose all answers that are correct.
A.Parallelogram JKLM is rotated 90° clockwise and then reflected across the y-axis to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.
B.Parallelogram JKLM is dilated by a scale factor of 6 and then translated 2 units down to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.
C.Parallelogram JKLM is translated 6 units up and then dilated by a scale factor of 10 to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.
D.Parallelogram JKLM is translated 8 units left and then reflected across the x-axis to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ

Answers

so if similar means that the points are in the same orientation reletive to each other (exg point 1 is to the right of point 2 and both are above points 3 and 4)


so rotations and reflections change the orientation reletive to each other so choices  A and D are out

Dialations and translations just move the whole thing, yet it stays the same points reletive to each other so the answers are B and C

Sorry if it is wrong, don't know this the best
I think the answer is B and C

Answer:

B.Parallelogram JKLM is dilated by a scale factor of 6 and then translated 2 units down to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ; and C.Parallelogram JKLM is translated 6 units up and then dilated by a scale factor of 10 to form parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ.

Step-by-step explanation:

Some transformations are called rigid transformations.  This is because they preserve congruence.  These are translations, rotations and reflections.  Any combination of these three transformations will result in congruent figures.

This means if we want similar and not congruent figures, the figure must be dilated.  The only two choices that mention dilations are B and C.
