Step-by-step explanation:

this worked on edg for me!

Given:

The area model for [tex]2.1\times 3.2[/tex].

To find:

The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

[tex]2\times 3=6[/tex]

[tex]2\times 0.2=0.4[/tex]

[tex]0.1\times 3=0.3[/tex]

[tex]0.1\times 0.2=0.02[/tex]

The complete area model is shown below.

After adding all areas of the area model, we get

[tex]6+0.4+0.3+0.02=6.72[/tex]

Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

Answer:

4/9

Step-by-step explanation:

He ate 1/3 of what he found. 2/3 or the 2/3 were left in the fridge.

2/3 · 2/3 = 4/9

Fourth ninths of the pizza is in the fridge.

Answer:

25; 15^2+20^2=625. 25^2=625, therefore the answer is 25.

Answer:

x/x+1

Step-by-step explanation:

[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]

start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)

So the fraction would be 4n/4(x-1)

Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses

The new equation would be

n*n-1/n+1

Now just multiply:

x/x+1

Answer:

B.) n/(n+1)

Step-by-step explanation:

Answer:

60 degrees

Step-by-step explanation:

s = r (theta)

(theta) = s/r

= 1 / (3/π) = π/3

as a degree π/3 x 180/π = 60

60 degrees

*Circumference = 2πr

6 = 2πr

r = 6/2π = 3/π

Answer:

3

Step-by-step explanation:

Answer:

Step-by-step explanation:

(1 - 4)/(2 -3) = -3/-1 = 3 is the slope

Answer:

B = -1

Your answer would be C

Answer:

b = -1

Step-by-step explanation:

-3(2x - 3) + 5x = bx + 9

-3 x 2x = -6x

-3 x -3 = 9

-6x + 9 + 5x = bx + 9

-6x + 5x = -1x

-1x + 9 = bx + 9

(cancel out everything except -1 and b)

-1 = b

Answer:

slope 1/2

Step-by-step explanation:

Answer:

3a+5b

Step-by-step explanation:

Variable 1:  a = candy corn

Variable 2: b = chocolate

Inequality 1:  60 ≥ 3a + 5b

Inequality 2: 20 ≤ 3a + 5b

The inequalities are as such because Josh needs to spend no greater than $60.  He must also buy at least 20 bags of candy.  The candy corn costs $3, while the chocolate costs $5.  An expression for the total cost of the candy would be 3a + 5b.

Answer:B i think if wrong im so sorry

Step-by-step explanation:

Answer:

B 75+25h

Step-by-step explanation:

$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

Answer:

f(x) = (x - 3)(x - 4)

Step-by-step explanation:

f(x)= x^2 - 7x +12 factors immediately into f(x) = (x - 3)(x - 4).

The roots are {3, 4}

Answer:

m<A=94

Step-by-step explanation:

(2x+10)+(2x+2)=180

4x+12=180

-12 -12

4x=168

/4 /4

x=42

m<A= 2x+10

m<A=2(42)+10

m<A=84+10

m<A=94

Check:

Add m<A and m<B which should equal 180.

m<B=2x+2

m<B=2(42)+2

m<B=84+2

m<B=86

94+86=180

Answer:

x = 6

Step-by-step explanation:

3x + 4 = 22

subtract 4

3x = 18

divide by 3

x = 6

Answer:

x=6

Step-by-step explanation:

Subtract 4 from each side of the equation to get 3x=18. divide 18 by 3 to get 6, and divide 3x by 3 to get x. x=6

Answer:

C)

[tex] \frac{1}{2} [/tex]

Step-by-step explanation:

Your problem should be set up like so:

[tex] \frac{1}{6} \div \frac{2}{6} [/tex]

When dividing fractions you multiply by the reciprocal of the second fraction. Therefore your question changes to this:

[tex] \frac{1}{6} \times \frac{6}{2} [/tex]

You multiply as across as normal and you'll end up with

[tex] \frac{6}{12} [/tex]

Which when simplified gives you

[tex] \frac{1}{2} [/tex]
