Question

a rancher wants to use 400 feet of fencing to enclose a rectangular area of 6400 square feet. what dimensions should the rectangle have ?

Solution 1

Lets l to be lenght, w width, p perimeter and a area:

a=lw

6400 ft²=lw

2(l+w)=p

2(l+w)=400 ft

l+w= 200 ft

l=200ft-w

substitute it instead of l to lw=6400ft²

(200-w)w=6400

200w-w²=6400

w²-200w+6400=0

(w-160)(w-40)=0

**w = 160ft**

**w = 40ft**

**l=200-w**

**l=200-160 = 40ft**

**l= 200-40 =160ft**

a=lw

6400 ft²=lw

2(l+w)=p

2(l+w)=400 ft

l+w= 200 ft

l=200ft-w

substitute it instead of l to lw=6400ft²

(200-w)w=6400

200w-w²=6400

w²-200w+6400=0

(w-160)(w-40)=0

Question

Enter the value of m when the expression 13.5x+m is equivalent to 2.7(5x-3.6)

Solution 1

We have that

13.5x+m =2.7(5x-3.6)

13.5x+m =2.7*5x-2.7*3.6

13.5x+m=13.5x-9.72

if the expression (13.5x+m) is equivalent to 13.5x-9.72

then

m=-9.72

**the answer is**

**m=-9.72**

13.5x+m =2.7(5x-3.6)

13.5x+m =2.7*5x-2.7*3.6

13.5x+m=13.5x-9.72

if the expression (13.5x+m) is equivalent to 13.5x-9.72

then

m=-9.72

Question

What is the greatest multiple of 7 that is less than 60

Solution 1

Find multipues of 7

use times tables if neccecary

7 times 1=7

7 times 2=14

7 times 3=21

7 times 4=28

7 times 5=35

7 times 6=42

7 times 7=49

7 times 8=56

7 times 9=63

63 is more so the answer is 56

use times tables if neccecary

7 times 1=7

7 times 2=14

7 times 3=21

7 times 4=28

7 times 5=35

7 times 6=42

7 times 7=49

7 times 8=56

7 times 9=63

63 is more so the answer is 56

Solution 2

The answer would be 56 because the multiples are 7, 14, 21, 28, 35, 42, 49, 56, and 63 and 63 is over 60 so the answer does have to be 56

Question

What is the volume of the triangular prism? 2cm , 5cm , 3 cm

Solution 1

Question

What do you do if there are no matching coefficients

Solution 1

You leave them like that

Question

Compare these integers by typing the symbol that will make the answer correct -6 ____ 3

Solution 1

3 is greater than -6. Therefore,

-6**<** 3.

-6

Solution 2

-6 is smaller than 3 so it would look like:

-6 < 3

-6 < 3
