Answer:

width = 15 inches

length = 30 inches

Step-by-step explanation:

Let width = w

Length =2w

Perimeter = 90 inches

2*(length + width) = 90

2*(2w +w ) = 90

2* 3w = 90

6w = 90

  w = 90/6

 w = 15 units

length = 2*15 = 30 units

The size of the bag to buy is 5-lb bag for $6.20

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, Frank can purchase bags of apples in four sizes.

To find the best size, checking for the price of bags per pound,

1) 2-lb bag for $3.33

so, for 1 pound = 3.33/2 = $1.665

2) 3-lb bag for $4.70

so, for 1 pound = $1.56

3) 4-lb bag for $5.14

so, for 1 pound = 5.14/4 = $1.285

4) 5-lb bag for $6.20

so, for 1 pound = 6.20/5 = $1.24

In all the four size, the 5 pound bag is cheapest.

Hence, The size of the bag to buy is 5-lb bag for $6.20

Answer:

y=x+1

Step-by-step explanation:

find 2 points which they are on the line

for example:

f(0)=1 Basically shows: x=0,y=1

f(1)=2 Also: x=1,y=2

Find the slope of the line

m=∆y/∆x

[tex]m = \frac{2 - 1}{1 - 0} = 1[/tex]

Also we know:

y-y0=m(x-x0)

Put one of the points instead of y0 & x0:

y-1=1(x-0)

y=x+1

(An easy way is: put 2 points of the line in this equation y=ax+b and find a and b)

Step-by-step explanation:

A quadratic is 'involving the second and no higher power of an unknown quantity or variable.'

Therefore, we can exclude b and d easily because both have a higher power of 2. 9x^(2) is not a binomial because it only has 1 term (i think its called a term) leaving A, x^2-16x as the only answer left.

Answer:

The dimensions of the Park is120m2

Step-by-step explanation:

remember, we need to get to an expression of the form

y = ax + b

1.

x + 5y = 5

5y = -x + 5

y = (-1/5)x + 1

2.

3x + 2y = 4

2y = -3x + 4

y = (-3/2)x + 2

3.

2x + y = 4

y = -2x + 4

4.

4x - 2y = 6

2y = 4x - 6

y = 2x - 3

5.

8x - 4y = 16

4y = 8x - 16

y = 2x - 4

6.

3x + 4y = 4

4y = -3x + 4

y = (-3/4)x + 1

7.

9x - 4y = -16

4y = 9x + 16

y = (9/4)x + 4

8.

2x - 5y = 10

5y = 2x - 10

y = (2/5)x - 2

9.

3x + 5y = 10

5y = -3x + 10

y = (-3/5)x + 2

10.

7x - y = 4

y = 7x - 4
