Answer:

The image of AB will be 15 cm long after dilation by a scale factor of 5.

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

Rule to calculate the mage of the segment AB after dilation of the segment AB by a scale factor 5 centered at the origin

AB = length → A'B'  = 5(length)

It means the length of the image of the segment AB can be determined by multiplying the length of the original segment AB by 5.

so

AB = 3 cm

Thus, the length of image A'B' will be:

A'B' = 5(3) = 15 cm

Therefore, the image of AB will be 15 cm long after dilation by a scale factor of 5.

Answer:

A.36m

C.-11m

D.2m

E.20m

Step-by-step explanation:

Sorry I forgot b

The final elevation of the given animals is as follows 1)Bird = 36m  2) butterfly = 4m 3) diver = -11m below sea level 4) whale = 2m 5) fish= -20 m

To get the sum of a negative and a positive number, use the sign of the larger number and subtract. For example: (–7) + 4 = –3. 6 + (–9) = –3.

Given here,1)  A bird starts at 20 m and changes 16m in a positive direction therefore net elevation is  20 + 16 = 36m

2)  A butterfly starts at 20 m and changes -16m, thus again net elevation is      

20-16 = 4m

3)  A diver starts at 5 m and changes -16m, the net depth of the diver below sea level is 5+(-16) = -11m

4)  A whale starts at -9 m and changes 11 m in the positive direction then net depth is -9+11 = 2m

5) A fish starts at -9 meters and changes -11 meters in the negative direction thus net depth is = 9-11= -20m below sea level

Hence these are the final answers.

Answer:

Dimension of the extended stage is; length = 6 m and width = 2x m

Step-by-step explanation:

Area of the rectangular outdoor = length x width

New area = area of the outdoor + area of the extended stage

                = 216 + 12x

                = 6(36 + 2x)

New area = 6 (36 + 2x)

So that;

The dimension of the rectangular outdoor = 36 x 6

i.e length = 36 m and width = 6 m

So that the dimension of the extended stage = length x width

                                     = (6 x 2x) m

i.e length = 6 m and width = 2x m

Answer:

The percent of decrease can be calculated with this formula:

(Original value - New Value)/(Original Value)

In this case, the original  value is 117 and the new value is 91.

So  the  percent of  decrease is 26/117, or about 22%.

Answer:

The wide of the rectangle = 42 inches

The  length of the rectangle = 43 inches

Step-by-step explanation:

Step(i):-

Given that the length of the rectangle = 10x-7

Given that the width of the rectangle = 6x +12

The perimeter of the rectangle = 2(length + width)

Given that the perimeter of the rectangle = 170

Step(ii):-

    2(length + width) = 170

        length + width = 85

        10x-7 +6x +12 =85

          16x +5 = 85

           16x = 85-5 = 80

             x =    [tex]\frac{80}{16}[/tex]

             x = 5

Final answer:-

The  length of the rectangle = 10(5)-7 = 50-7 = 43

The wide of the rectangle = 6x +12 = 6(5) + 12 = 30+12 =42

The perimeter is the sum of its all sides. The rectangle is 42 inches wide.

The perimeter is the sum of its all sides. The perimeter of the rectangle is twice the sum of its length and its width.

[tex]\rm \text{Perimeter of rectanle}=2(Length +Breadth)[/tex]

As it is given to us that the length of the rectangle is (10x-7), while the width of the rectangle is (6x+12). Also, the perimeter of the rectangle is 170 inches. Therefore, using the formula of the perimeter of the rectangle we will get,

[tex]\rm Perimeter=2(Length +Breadth)\\\\170=2[(10x-7)+(6x+12)]\\\\170=2{10x-7+6x+12}\\\\170=2(16x+5)\\\\170=32x+10\\\\32x=160\\\\x=\dfrac{160}{32} = 5[/tex]

Now, substitute the value of x,

The width of the rectangle = 6x + 12 = 6(5)+12 = 30+12 = 42 inches.

Thus, the width of the rectangle is 42 inches.

Answer:

The original price is $650

Step-by-step explanation:

There's an actual algebra method for this, but this is my method because I find it way easier to remember.

Since the most you can discount out of an item is 100% (well, it's considered free then) let's subtract 100 - 34, which is 66.

Now, turn it into a decimal because it makes the numbers easier- 0.66.

Since when you're finding the discount of an original price, you multiply the original price by the discount- instead for finding the original price for a discounted item we divide $429 by 0.66 instead, since when you divide a number by another number that's under 1 the quotient is a larger number.

So, 429 ÷ 0.66 = 650.

Therefore, the original price of the $429 sale price for a 34% discount is $650.

x=11 please correct me if i'm wrong. I hope I helped.

Step-by-step explanation:

2x-5=8

add 2 to both sides

so the 2 on the left cancels out, and now on the right it is 6

now add 5 to both sides, so x is by its self and on the right of the equation sign it is 11

so x=11

Given:

Last year, Dr. Alvarado saw 540 patients.

This year, he saw 1053 patients.

To find:

The percent of increase in the number of patients seen each year.

Solution:

We know that,

[tex]\%\text{Increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

On substituting the given values, we get

[tex]\%\text{Increase}=\dfrac{1053-540}{540}\times 100[/tex]    

[tex]\%\text{Increase}=\dfrac{513}{540}\times 100[/tex]

[tex]\%\text{Increase}=\dfrac{5130}{54}[/tex]

[tex]\%\text{Increase}=95\%[/tex]

Therefore, the number of patients increased by 95% each year.
