Using algebra tiles, show a model of 4x + 2.

Answer:

Look below.

Step-by-step explanation:

Our goal when solving a system of equations is to reduce two equations that have two variables, down to a single equation with one variable.  

here's your solution

=> it is given that.

=> height of cylinder = 15unit

=> radius of base = 9unit

=> volume of cylinder = π r^2h cubic unit

=> now, putting the value of height and radius

in above formula

=> volume = 22/7 *9*9*15

=> volume = 36177cubic unit

The value of volume of cylinder is,

⇒ volume = 36177 cubic unit

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

We have to given that.

In a cylinder;

Height of cylinder = 15unit

And, radius of base = 9unit

Since,  We know that;

volume of cylinder = π r²h cubic unit

Now, putting the value of height and radius as;

⇒ volume = 22/7 x 9x 9 x 15

⇒ volume = 36177 cubic unit

Thus, The value of volume of cylinder is,

⇒ volume = 36177 cubic unit

Answer:

can you put a picture of the shape

Step-by-step explanation:

Answer:

424 cm²

Step-by-step explanation:

The figure is composed of a square and a trapezium on top

A of square = 18² = 324 cm²

A of trapezium = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 8, b₁ = 18 and b₂ = 7 , then

A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²

Area of hexagonal park = 324 + 100 = 424 cm²

T = 6.41 hours

Step-by-step explanation:

Fishing for Friday =  3 7/12 hours

Fishing for Saturday  =2 5/6 hours

We need to find for how long Diana went fishing on Friday and Saturday combined. It means we need to add the time for Friday and Saturday. So,

[tex]T=3\dfrac{7}{12}+2\dfrac{5}{6}\\\\=\dfrac{3(12)+7}{12}+\dfrac{2(6)+5}{6}\\\\=\dfrac{43}{12}+\dfrac{17}{6}\\\\=6.41\ \text{hours}[/tex]

So, the combined timing is 6.41 hours.

Answer:

y=-2 (Please can i have brainliest????)

Step-by-step explanation:

There are different ways to do this but my way, you would distribute 6 to both y and 4, ending up with 6y+24=12. You then subtract 24 from both sides giving you, 6y=-12. Then divide both sides by 6, giving you y=-2

Answer: y=-2

Step-by-step explanation:

First, you would distribute the 6 to both the y and the 4 which would give you 6y+24=12

Then you would subtract 24 from 12 to get -12 ( it would look like 6y= -12 after)

Finally, you would take -12/6 to get -2 so y = -2

Answer:

7.2

Step-by-step explanation:

Use the distance formula:

d = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

Points of the diagonal: (-2, -2) and (2, 4)

d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]

d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]

d = [tex]\sqrt{(4)^2+(6)^2}[/tex]

d = [tex]\sqrt{16 + 36}[/tex]

d = [tex]\sqrt{52}[/tex]

d ≈ 7.2

Answer:

7 ( b + 4 ) = 9

Step-by-step explanation:

Let the number be = b

It is given that the :

The number is added to 4.

And the value is equal to 9 when it is 7 times the sum of the number, b and 4.

Thus according to the question, the sentence can be translated in equation form as :

7 ( b + 4 ) = 9

Thus in other word, we can say that the addition of (b + 4) when it is multiplied for 7 times, we get the result as 9.

Answer:

B

Step-by-step explanation:

[tex]x^{0} = 1\\\\\frac{x^{m}}{x^{n}}= \frac{1}{x^(n-m)}}, n >m\\\\\\\frac{6ab}{(a^{0}b^{2})^{4}}=\frac{6ab}{(1*b^{2})^{4}}\\\\=\frac{6ab}{b^{2*4}}\\\\=\frac{6ab}{b^{8}}\\\\=\frac{6a}{b^{8-1}}\\\\=\frac{6a}{b^{7}}[/tex]

The equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7

The expression is given as:

6ab/(a^0b^2)^4

Evaluate the exponent of 0

6ab/(b^2)^4

Apply the law of indices, and open the bracket

6ab/b^8

Apply the law of indices

6a/b^(8-1)

Evaluate the difference

6a/b^7

Hence, the equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7

Answer:

25% of the length is 7.5 (seven and five tenths) feet

Step-by-step explanation:

25% of 30

7.25 feet is 25% of length.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

The length of wall is 30 feet.

So, 25% of length

= 30 x 25/100

= 30 x 1/4

= 30/4

= 7. 25 feet

Hence, 7.25 feet is 25% of length.
