Step-by-step explanation:

3 bears = 3

1 bear = 3 ÷ 3

1 bear = 1

2 glasses + 1 bear = 5

2 glasses + 1 = 5

2 glasses = 5 - 1

                = 4

1 glasses = 4 ÷ 2

1 glasses = 2

1 Cyxus + 1 bear + 1 Cyxus + 1 glasses = 9

2 Cyxus + 1 + 2 = 9

2 Cyxus = 9 - 1 - 2

              = 6

1 Cyxus = 6 ÷ 2

1 Cyxus = 3

1 glasses + 1 bear + 1 glasses + 1 Cyxus - 1 bear - 1 glasses = ?

2 + 1 + 2 + 3 - 1 - 2 = 5

Answer:

10.6

Step-by-step explanation:

Answer:

She would be using 10.6 feet of wood.

Step-by-step explanation:

Multiply 2.65 (the length of the wood) by 4 (the number of pieces) and you would get 10.6 (the total measurement of the wood she has).

Step-by-step explanation:

(a) 3, 10, 17, 24, ...

d=10-3=17-10=7 then it is arithmetic sequence

a(n) = a +(n-1)d

a(11) = 3 +(11-1)7

       =73

(b) 4, 12, 36, 108,

r=12/4=36/12=108/36=3    

So it is geometric

By using this equation:

and we have a(1)=4 , r=3    

a(11)=4*(3)^(11-1)

      =236196

(c) -20, -24, -28, -32, ...

d=-24+20=-28+24=-4 then it is arithmetic sequence

a(11) = -20 +(11-1)-4

       =-60

Answer:

1.25x + 1.49 = 100

Step-by-step explanation:

1.25  =  Water bottle selling price

x = number of water bottles

1.49 = Ice tea sell price

Missing = number of ice tea bottles

100 = Total selling price

Mistake:

Barbara’s equation did not consider the number of bottles of iced tea

Answer:

Step-by-step explanation:

Answer is "B"

Answer:

sin a= 4/5 tan b=3/5

im not 100% sure but im open for suggestions

Answer:

x must equal 5 and y must equal 2

therefore,

5a + 2b = 23 and

5a - 2b = 7.

I'm gonna take 5a + 2b = 23 and add 7 to each side:

5a + 2b + 7 = 30

and substitute 5a -2b in for 7 on the left side:

5a + 2b + (5a-2b) = 30

10a = 30

a = 3

Now we know a. Now take

5a -2b = 7

and substitute in 3 for a

5*(3) - 2b = 7

15 -2b = 7

8 = 2b

b = 4

a = 3 and b = 4

Step-by-step explanation:

Equation is y = -3/4x + 12.

Answer:

A) $0.6

The point (5,3) means that you get 5 pounds of lettuce for 3 dollars, which means that one pound of lettuce would cost 3/5 dollars.

B) It tells us that 10 pounds of lettuce costs $6.

The x value of the point on the this graph tells us the number of pounds of lettuce and the y value of the point tells us the cost of those pounds of lettuce.

Answer:

8 units

Step-by-step explanation:

Given the relationship between the radius, r, of a sphere and its surface area, A expressed as;

r = 1/2( A /4 π )

We are to find the radius r when Area A is 64π

Substitute A = 64π  into the expression and get r as shown;

Recall that: r = 1/2( A /4 π )

r = 1/2( 64 π/4 π )

r = 1/2(16)

r = 16/2

r = 8units

Hence the radius of the sphere will be 8 units

Yes

Answer:

9 shelters

Step-by-step explanation:

Subtract 64 from the total number of coats to get the total amount of coats donated to shelters:

388 - 64 = 324

Then, divide 324 by 36, since that's the minimum number of coats given to each shelter:

324 ÷ 36 = 9

So at least 9 shelters received coats.

Dee gives a minimum of 36 coats to each shelter, 9 shelters receive coats.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Dee has collected no fewer than 388 coats for charities.

Let n be the number of coats.

n = 388

She gave 64 of the coats to her church and donated the remaining coats equally to local shelters.

Then,

n = 388 - 64

n = 324

The 324 remaining coats equally to local shelters.

She gave 36 to each shelter.

That means, use division operation,

the number of shelters = 324 / 36

The number of shelters = 9

Therefore, the number of shelters is 9

Answer:

Not similar

Step-by-step explanation:

For a rectangle you would make a equation with length a over length b equalibg width a over width b. I'll use the problem and show it in an equation below.

[tex] \frac{12}{24} = \frac{8}{18} [/tex]

There are a few ways to solve this, 1, by simplifying, and the other cross multiplying. I like cross multiplying more, so I'll explain it like that. To cross multiply you multiply the numerator of one fraction by the denominator of the other.

[tex]12 \times 18 = 216 \\ 24 \times 8 = 192[/tex]

Because these values are not equal, the rectangles are not similar.

Answer:

[tex]2\sqrt {2}[/tex]

Step-by-step explanation:

Distance From a Point to a Line

Given a line with an equation :

ax + by + c = 0

And the point [tex](x_0,y_0)[/tex]

The distance from the line to the point is given by

[tex]\displaystyle d=\frac {|ax_{0}+by_{0}+c|}{\sqrt {a^{2}+b^{2}}}[/tex]

The triangle has a vertex at (1,-2) and the base lies on the equation

x + y = 3

Rearranging:

x + y - 3 = 0

The altitude of the triangle is the distance from the point to the line.

The values to use in the formula of the distance are: a=1, b=1, c=-3, xo=1, yo=-2:

[tex]\displaystyle d=\frac {|1*1+1*(-2)-3|}{\sqrt {1^{2}+1^{2}}}[/tex]

[tex]\displaystyle d=\frac {|1-2-3|}{\sqrt {2}}[/tex]

[tex]\displaystyle d=\frac {4}{\sqrt {2}}[/tex]

Rationalizing:

[tex]\displaystyle d=\frac {4}{\sqrt {2}}\cdot\frac{\sqrt {2}}{\sqrt {2}}[/tex]

[tex]\displaystyle d=2\sqrt {2}[/tex]

The altitude of the triangle is [tex]\mathbf{4\sqrt {2}}[/tex]

Answer:

D is the extraneous ratio

Step-by-step explanation:

A is correct because 72/27 = 2.67, 64/24 = 2.67

B is correct because 25/10 = 2.5, 10/4 = 2.5

C is correct because 30/6 = 5, 35/7 = 5

D is extraneous (incorrect) because 7.5/ 5 is 1.5 and 18/1 is 18, two very different answers
