What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 7.5?A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm.

Perimeter = 58 cm, area = 209.25 cm2

Perimeter = 58 cm, area = 2,700 cm2

Perimeter = 210 cm, area = 2,700 cm2

Perimeter = 210 cm, area = 209.25 cm2

Answers

Answer 1

Answer:

Answer with Step-by-step explanation:

The perimeter(P) and area(A) of a rectangle is given by:

P=2(l+w)

A=lw

Where l is the length and w is is the width of the rectangle

original length and width

l=8 cm

w=6 cm

New length and width

l'=8×7.5=60 cm

w'=6×7.5=45 cm

P=2(60+45)

=210 cm

Area=60×45

=2700 cm²

Hence, Correct option is:

Perimeter = 210 cm, Area = 2,700 cm²

Answer 2

Answer: enlarged by a scale factor of x means times each dimention by x

P=2(L+W)
A=LW

original L and W
L=8cm
W=6cm

new
nL=8*7.5=60cm
nW=6*7.5=45cm

newP=2(60+45)=2(105)=210cm
newA=(60)(45)=2700cm^2

Of the 48 oranges in a carton 1/3 of them were rotten Ben and David took the remaining good oranges it's been took eat my oranges and David how many oranges did David take

Answers

Answer:

David took 16 oranges.

Step-by-step explanation:

We are given the following in the question:

Total number of oranges = 48

Oranges rotten =

$(1)/(3)$

Number of oranges rotten =

$(1)/(3)* 48\n\n=16$

There were 16 rotten oranges.

Number of good oranges left =

$= 48-16\n=32$

These are equally divided among Ben and David.

Number of oranges each Ben and David get =

$(32)/(2) = 16$

Thus, David took 16 oranges.

Perimeter = 114
Length = 5x + 17
Width = 3x + 24

Perimeter = 2L + 2W
114 = 2(5x+17) + 2(3x+24)
114 = 10x + 34 + 6x + 48
114 = 16x + 82
114 - 82 = 16x
32 = 16x
32/16 = x
2 = x

Length = 5x + 17 = 5(2) + 17 = 10 + 17 = 27
Width = 3x + 24 = 3(2) + 24 = 6 + 24 = 30

When Mac was asked to duplicate Angle TAR, he used his protractor to measure angle TAR and then to make Angle MAC. Is his construction correct? Explain.

Answers

There is no image! Next time, use an image attached to your question. You can take a screenshot, or a picture of your screen with another device.

Final answer:

Mac was somewhat correct in utilizing a protractor to duplicate angle TAR. However, in geometric construction, angles are usually duplicated using a compass and straight edge.

Explanation:

In terms of duplicating angle TAR to create angle MAC, Mac was somewhat correct in his use of a protractor to measure and recreate the angle. However, the exact correctness of his construction could be contingent upon additional elements. In simple terms, yes, you can duplicate an angle by using a protractor. You would simply need to measure the degree of the original angle and then replicate this on a separate point using the same degree measurement. Nonetheless, in proper geometric construction, an angle is duplicated using a compass and a straight edge rather than a protractor.

For instance, if Angle TAR measures 30 degrees, Mac will set his protractor at an intersect point M to measure and create angle MAC, that also measures 30 degrees. It's essential to note that while the measure of the angles are identical, the lengths of the sides of the angles will not necessarily be identical unless defined to be so.

Yet, using a protractor is not necessarily the exact method of angle duplication as described in classic geometric construction. There, one uses a compass and straightedge to duplicate an angle. This process generally involves drawing an initial line, creating an arc crossing the angle's sides with a compass, and then duplicating this arc on the other line to assure both angles are comparable.

Find an equivalent function to f(x) = 5(3)3x.

Answers

f(x) = 5(3)^(3x) = 5(3^(3x)) = 5(27)^x = 5(27)x

The correct result would be f(x) = 5(27)x.

f(x) = 5(3)3x

= 5*3*3*x

= 45x

So an equivalent function is f(x) = 45x

f(x) = 45x

Hope this helps.
