Answer:
The system of equation used to find the dimension of the wooden deck in feet are
.
Step-by-step explanation:
Given:
Perimeter of deck = 90 feet.
We need to find the system of equation used to determine the dimension in feet of the wooden deck.
Solution:
Let the length of the deck be 'l'.
Let the width of the deck be 'w'.
Now Given:
The deck's length, l, is 5 feet less than 4 times its width, w.
So we can say that;
Length of the deck is equal to 4 times width minus 5.
framing in equation form we get;
⇒ Equation 1
Now we know that;
Perimeter of the rectangle is given by 2 times Length times width of the rectangular deck.
framing in equation form we get;
⇒ Equation 2
Hence The system of equation used to find the dimension of the wooden deck in feet are
.
Answer: The correct option is 4.
Explanation:
The given function is,

It is an exponential function and 2>1, therefore it is an increasing in nature.
put x=0 in the given function to find the y-intercept of the graph.




So, the y-intercept is 1.5.
In figure 1 and figure 1 the y-intercept is 1, in figure 2 the y-intercept is 2 , therefore first three options are incorrect.
In figure 4 the y-intercept is 1.5, therefore the option 4 is correct.
Answer:129
Step-by-step explanation:(621 x 0.25) + (750 x 0.10) = 230.25
750 - 621 = 129 more dimes than quarters
Answer:
c=8
Step-by-step explanation:
do find c, we do 64/8=8. We can check our work by doing 8*8 which is in fact 64
Answer:
The best estimate is $1.97 per gallon
Step-by-step explanation:
Take the Cost- 39.95 then divide it by the gallons- 20.3 this gives you the price per gallon
