A 2 pound bag of wildflower send covers 4 square feet how many of seed it takes to cover 1 square foot
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

2 lb bag to 4 sq ft = 1 lb bag to x sq ft

2 / 4 = 1 / x

cross multiply because this is a proportion

(2)(x) = (1)(4)

2x = 4

x = 4/2

x = 2 <==== so a 1 lb bag covers 2 sq ft

Simplify: 4^ sqrt 400/ 4^ sqrt 5 <br> SHOW WORK
USPshnik [31]

Given  

The equation is in the form

=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}

Simplify the above equation

To proof

As given in the question the equation is written in the form

=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}

By using the exponent property

when you divide powers with the same base you just have to subtract the exponents. i.e

\frac{y^{a}}{y^{b}} = y^{a-b}

y is not equal to zero.

Now apply this property to the above equation

=4^{\sqrt{400}- \sqrt{5}}

As

\sqrt{400} = 20

now put this in the above equation

we get

=4^{20- \sqrt{5}}

Hence proved

a first number plus twice a second number is 4. twice the first number plus the second number totals 26. find the numbers
blagie [28]

Answer:

a = 16

b = -6

Step-by-step explanation:

a + 2b = 4

2a + b = 26

2a + 4b = 8

2a + b = 26

3b = -18

b = -6

a + 2(-6) = 4

a - 12 = 4

a = 16
