Answer:

[tex]3(x-3)^{2} - 15[/tex]

2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray.

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

Explanation:

Consider the problem of 0.68 of 1, in other words 0.68*1 or simply 0.68

The number 0.68 is 68/100 or 68 over 100. We can have a 10 by 10 grid of tiny squares. Shade in 68 of them to represent 0.68 aka 68 hundredths.

So you'd have 6 full rows shaded  (to account for 0.60 so far) and then an additional 8 squares in the seventh row (adding on 0.08 to get 0.60+0.08 = 0.68)

All of this is for one square. Double this process and you'd get 0.68*2 to represent the value 1.36

In total, 2*68 = 136 squares are shaded out of 2*100 = 200 squares total.

Answer:

31.6

i think

Because 39 1/2 divided by 1 1/4 is  31.6

Hope This Helps

Answer:

31.6

Step-by-step explanation:

Alright lets take a deep look at the question. It is asking for the miles/gallon, or miles per gallon so we already have our format set. Now for the important information, how do we find unit rate?

Simply put, we divide the unit numerator by the quantity in the denominator. Alright, so we have 39.5/1.25 already, which gives us a highway to our answer through dividing the numbers as they are shown.

Therefore, our unit rate is 31.6 miles per every gallon of fuel.

Answer:

20°

Step-by-step explanation:

1) Opposite angles are equal, so the opposite will be 140°.
2) Then, you do 140+110+90+90 (since A and D are at right angles) which gets you 430°

3) Finally, since its a pentagon, you do 540° - 430° which is 110°

Answer:

1.728

Step-by-step explanation:

1.2^3 = 12^3/10^3

12^3/10^3 = 1728/1000

1728/1000 = 1.728

Answer:

B

Step-by-step explanation:

Add the number of the remaining cards

8 cards of tomatoes + 3 remaining cards of carrots

since Lidia turned the cards and put away 1 carrot card.

At first she had 4 on the table but now she has 3

So, add 8+3= 11

The question is asking... what is the probability that the card Lydia turns over has a carrot on it.

so we put the number of remaining carrot cards over the total number of cards.

Answer:

longer base: 10 2/3

shorter base: 5 1/3

Step-by-step explanation:

you first take 32 divided by 4 and then multiply that by 2 and you get 16 and then you divide that by 3 and you get 5 1/3 but then the longer one is 5 1/3 plus 5 1/3 (i hope that makes sense)

Answer:

10.53 m

Step-by-step explanation:

since the two triangles that are formed are similar triangles, you can find out that by how much the base of the small triangle is getting larger in the bigger triangle by dividing the two measurements. after finding out that the scale factor is 9.16, i multiplied the height of the person by 9.16 to figure out the height of the school building since they are similar

hope u get it:)

Answer:

I think its 345.6m^3

Step-by-step explanation:

Volume=Base x Height

Volume=(4.8 x 7.2) x 10

Volume=34.56 x 10

Volume is 345.6 m^3

Answer:

a) 2.5π, b) ≈673 times

Step-by-step explanation:

diameter = 2.5

circumference = diameter*π

circumference = 2.5π

5280/2.5π

≈5280/2.5*3.14

≈5280/7.85

≈672.6, ≈673

Answer:The number of all possible codes = 26 * 26 * 10 * 10 * 10 = 676000

Step-by-step explanation:

five digit code; each code is 3 digits (0-9) followed by two letters. That's ten numbers to choose from and 26 letters in the alphabet.

The problem suggests numbers and letters can be used more than once, like having a code: 555AA

To find the number of possible codes, you multiply by the choices for each digit.

10*10*10*26*26 = 676,000

Answer:

26 * 26 * 10 * 10 * 10 = 676000

Step-by-step explanation:

Answer:

The scale factor was x3

Step-by-step explanation:

3 x 3 = 9. 5 x 3 = 15. So the scale factor is times 3 or x3.

Answer:

The scale factor is 3

Step-by-step explanation:

this is because if you divide the length or the width of rectagle B by 3, it will give you the length or width of rectangle A

The area of the circle is the amount of space on the circle

The area of the circle is about 14 cm²

From the question, we understand that the circle fits perfectly into the grid.

This means that the area of the circle is about the same with the area of the square grid.

The area  of the square grid is:

Area = 4 * 4

Evaluate

Area = 16

The surrounding areas are triangles with the following estimated dimensions:

Base = 1.5, Height = 1.5

The area of the four triangles is:

Area = 4 * 0.5 * 1.5 * 1.5

This gives

Area = 4.5

Subtract the area of the triangle from the square

Remaining area = 16 - 4.5

Remaining area = 11.5

Approximate

Remaining area = 12

Hence, the area of the circle is about 12 cm²

To improve the grid, we simply get the actual dimension of the black region
