In 10 years, he will be 2 less than Julio's age
times 3. How old are Julio and his father?

Answer: D.  T <-9, -2> (ΔABC) = ΔDEF

Step-by-step explanation:

D = A

A (3, 0) --> D (-6, -2)

To get the x-coordinate of D, you add -9 to 3

To get the y-coordinate of D, you add -2 to 0

T <-9, -2> (ΔABC) = ΔDEF

Answer:

2000

Step-by-step explanation:5%= 100 nickels

1%= 20 nickels

20 x 100 = 2000

Answer:

2,000

Step-by-step explanation:

If 5%=100 nickels , then 20x100=the number of nickels Chi has.  

20x100=2,000

Answer:

x +10 =0 (1)

-8x -9y=1 (2)

x=-10 => (2) 80-9y=1 =>y=9

=> x=-10, y=9

Step-by-step explanation:

3a² - 24ab + 48b² = 3 ( a - 4b )²

We will start by rewriting the given quadratic polynomial,

3a² - 24ab + 48b²

Taking out the common "3",

=> 3 ( a² - 8ab + 16b² )

Splitting the middle term i.e. " - 8ab " appropriately,

=> 3 ( a² - 4ab - 4ab + 16b² )

=> 3 [ a ( a - 4b ) - 4b ( a + 4b ) ]

=> 3 ( a - 4b ) ( a - 4b )

Hence, option C is correct.

Answer:

[tex]\huge\boxed{\tt{ 3 (a-4b)(a-4b)}}[/tex]

Step-by-step explanation:

[tex]\sf 3a^2-24ab+48b^2\\\\Taking \ 3 \ as \ common\\\\= 3 (a^2-8ab+16b^2)\\\\= 3 [(a)^2 - 2 (a)(4) + (4b)^2]\\\\Using \ Formula \ a^2 - 2ab + b^2 = (a-b)^2\\\\= 3 (a-4b)^2\\\\= 3 (a-4b)(a-4b)\\\\\rule[225]{225}{2}[/tex]

Answer:

The range of #1 is 13

The range of #2 is 9

The range of #3 is 20

The range of #4 is 59

Step-by-step explanation:

I had a math teacher in 6th grade who taught me a corny, but helpful rhyme.

It is

Hey diddle-diddle

The median's the middle (organize the numbers from least to greatest, then find the number in the middle)

You add (all the numbers), then divide (by how many numbers there are) for the mean

The mode is the one that appears the most (which number do you see more than once?)

The range is the difference between (find the smallest number and the largest number, then subtract the small one from the large one)

See? Corny huh? I hope this helps bro!

The range of data: [tex]52,48,57,47,49,60,59,51[/tex] is [tex]13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex] is [tex]9[/tex]

The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex] is [tex]59[/tex]

What is range?

In statistics, the range of a set of data is the difference between the largest and smallest values. Difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.

According to question, we have to find different range.

The range of data: [tex]52,48,57,47,49,60,59,51[/tex]

[tex]=60-47=13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex]

[tex]=13-4=9[/tex]

The range of data: [tex]97,106,99,97,115,95,108,100[/tex]

[tex]=115-95=20[/tex]

The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex]

[tex]=71-12=59[/tex]

Hence, we can conclude that

The range of data: [tex]52,48,57,47,49,60,59,51[/tex] is [tex]13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex] is [tex]9[/tex]

The range of data:[tex]97,106,99,97,115,95,108,100[/tex] is [tex]20[/tex]

The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex] is [tex]59[/tex]

Answer:

541.1 square feet

Step-by-step explanation:

A = πr²

1) convert in. to ft because answer is in sq. ft

78 in => 6.5 ft

2) Find radius of entire area

6.5 ft + radius of inner circle

6.5 + 10 = 16.5

3) Calculate area of combined circles

A = π(16.5)²

A = 855.3 sq. ft

4) Find area of inner circle

A = π(10)²

A = 314.2 sq. ft

5) Subtract area of inner circle from combined area

855.3 sq ft - 314.2 sq. ft = 541.1 sq. ft

Answer:

The value of x is 3

Step-by-step explanation:

Here, we want to find the value of x

to do this, we apply the principle of similar triangles

That would work as follows;

4/x + 5 = 7/(2x + x + 5)

4/x + 5 = 7/3x + 5

4(3x + 5) = 7(x + 5)

12x + 20 = 7x + 35

12x - 7x = 35-20

5x = 15

x = 15/5

x = 3

These are interval for increasing (doesnt include relative max-min)

Step-by-step explanation:

Increasing means when we input the value of x and we get the increase of y-value.

A bit hard to imagine? You can look at the graph instead. The name already says it all, Increasing Graph. The graph keeps rising and rising till the max and that is increasing.

The decreasing is when the graph decreases to minimum. The graph would face down for decreasing.

Since we only want the increasing. We look at the graph and tell which region does the graph face up and that is the increasing.
