Coordinate Plane Dilation

Divide the total amount of money you have by the cost of one package of blueberries.

If one package of blueberries is $5, and you have $15, divide 15 by 5

15 ÷ 5 = 3

You can buy 3 packages of blueberries with $15 dollars.

In a proportional relationship, the ratios of the x and y variables are equivalent.

To find out if this relationship is proportional, take two of the points and convert them to fractions (x over y).

(1, 5) & (3, 15) ⇒ [tex]\frac{1}{5}[/tex] & [tex]\frac{3}{15}[/tex]

Divide the numerators and denominators by each other. If they both equal the same number, the relationship is proportional.

3 ÷ 1 = 3 ,,, 15 ÷ 5 = 3

Yes, the relationship is proportional.

Answer:

2:5

Step-by-step explanation:

[tex]12\:squares\\8\:triangles\\\\Total\:shapes =12+8 =20\\\\Triangles: Total\:shapes\\8 : 20\\\\Cross\:cancel\:common\:factor\:4\\\\2 :5[/tex]

The ratio triangles to total shapes is → 2 : 5.

We have 12 squares and 8 triangles.

We have to determine the simplest ratio of triangles to total shapes.

The ratio of number of toffees to the total number of sweets in a jar is -

[tex]$R \;- > \frac{10}{10+15} = \frac{2}{5}[/tex]

R → 2 : 5

According to the question, we have -

Total number triangles = 8

Total number of Shapes = 12 + 8 = 20

The Ratio of number of Triangles to total number of shapes = [tex]$\frac{8}{20}[/tex] = [tex]$\frac{2}{5}[/tex]

Hence, the ratio triangles to total shapes is → 2 : 5.

All I can tell u is that the exponent is the number of times the decimal moves

Step-by-step explanation:

As the other answer stated, the exponent is the number of times the decimal moves. If the decimal moves forward, the exponent is positive, and if the decimal moves backward, the exponent is negative.

-580,000 =  -5.8 × 10^5

26,400,000 =  2.64 × 10^7

0.000135 =  1.35 × 10^-4

0.000002 =  2 × 10^-6

155,000,000 =  1.55 × 10^8

0.00000014 =  1.4 × 10^-7

0.0003 =  3 × 10^-4

7,800,000 =  7.8 × 10^6

0.0467 =  4.67 × 10^-2

3,500 =  3.5 × 10^3

900 =  9 × 10^2

1,000,000,000 = 1 × 10^9

nah my brain is dead like I'm stuck In science ugh

Step-by-step explanation:

but from what I can see 15 is 9 tenths and 7 hundredths ya

Answer:

Step-by-step explanation:

Changing Percents to Decimals

The word percent means "per 100."  20% means 20 out of 100, or 20/100.   67% means 67 out of 100, or 67/100.  So to change a percent to a decimal, you simply divide the percentage number by 100.  When you divide by 100, the decimal just moves over 2 places to the left.

Changing Percents to Fractions

Remember, the word percent means "per 100."  This means you can change a percent to a fraction by dividing by 100.  Don't stop here though, make sure to simplify the fraction if possible.  Look to see if the numerator and denominator can be divided by the same number.

Changing Decimals to Fractions

First, figure out the place value of the last digit on the right.  Is it in the tenths place? Hundredths? Thousandths?  Use the place value to write the decimal as a fraction over 10, 100, 1000, etc. Then simplify the fraction if possible.

Remember, the first place to the right of the decimal is the tenths place.  The second place is the hundredths, then thousandths, ten thousandths, and so on.  

Answer:

The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.

Step-by-step explanation:

If we say [tex]x[/tex] is the first number, then the next consecutive number will be [tex]x+1[/tex].

Using this, we can make an equation.

[tex]x+(x+1)=55[/tex]

[tex]2x+1=55[/tex]

[tex]2x=54[/tex]

[tex]x=27[/tex]

And so we know that the two consecutive numbers are 27 and 28.

Step-by-step explanation:

You first have to know what all those words mean.

 -A rational number is a number who can be expressed in a ratio, and a  

  fraction.

-A integer includes a whole number and negatives numbers that is not a

 fraction. Ex: -0, 1....

-Whole numbers are numbers are whole numbers up to infinity Ex: 1,2,3

*Extra tip:

The difference between integer numbers and whole numbers is that integer numbers contain all whole numbers that are positive and negative up to infinity. But Whole numbers don't contain negative numbers.

Answer:a lot of speed

Step-by-step explanation:

Answer:

11. x = -16

12. k = 6

13. x = -19

14. x = -6

15. x = -20

16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?

17. x = 19

18. n = -10

19. b = 11

20. n = 4

21. r = -6

22. n = -4

Again super sorry about question 16 :(

Answer:

Step-by-step explanation:

11) -1= x/16

x= -16(because when dividing a negative and positive number the answer is always a negative.

12) 7=1+k

k=7-1

k=6

13) x-6=-25

x=-25+6

x=-19

14) -8x=48

x=48/-8

x= -8

15) x/10=-2

x=10*-2

x=-20

Answer:

x=6 and y=14

Step-by-step explanation:

First lets solve x

We substitute y for 0

So then this is how it turns out:

7*x+3*0=42

To find x you divide 42 and 7 and it becomes 6

Then lets solve y

We substitute x for 0

So then this is how it turns out:

7*0+3*y=42

To find y you divide 42 and 3 and it becomes 14.

THUS x=6 AND y=14

Answer: A - 30 cubes

B - Volume of prism =  feet³

Step-by-step explanation: We are given that the dimensions of the rectangualr prism is,

Length =  =  feet

Width = 1 foot

Height =  =  feet

Thus, the volume of the prism = Length × Width × Height

i.e. Volume of the prism =  × 1 ×  =  feet³

Now, the side of the cube =  foot each.

Volume of the cube =  =  feet³
