What is the cost of a table with 17 feet by 10 feet that cost $16 per feet

Answers

Answer 1

Answer: 17+10=27
27×16=$432 is the amount the table costs

Answer 2

Answer: 34 per feet because if you count to 16 it will be 34

15. The lines are perpendicular.

16. The lines are neither perpendicular nor parallel.

Step-by-step explanation:

15. The given lines are

Y=-3x+7 & -2x+6y=3 or, 6y = 3 + 2x or, $y = 0.5 + (x)/(3)$ .

The slope of the first line is -3 and the slope of the second line is $(1)/(3)$ [Comparing with the standard form of equation of straight line y = mx + c, where m is the slope of the straight line].

Two straight lines will said to be perpendicular to each other, if the product of its slopes will be equal to -1.

Since, $-3 * (1)/(3) = -1$ , the equations are perpendicular with respect to each other.

16. The lines are $y = -(x)/(5) + 6$ and -2x + 10y = 5 or, 10y = 5 + 2x or, $y = 0.5 + (x)/(5)$ .

As per the question number 15, it is clear that these equations are not perpendicular.

Here, the slope of the first one is $(-1)/(5)$ and the slope of the second one is $(1)/(5)$ .

The values are same with different sign. Hence, these equations are not parallel too.

Jessica is making 2 loaves of banana bread. She needs 3/4 cup of sugar for each loaf. Her measuring cup can only hold 1/4 cup of sugar. How many times will Jessica need to fill the measuring cup in order to get enough sugar for both loaves of bread?

Answers

3/4*2
=6/4
6/4/1/4
=6/4*4
=6
so 6 pours

Answer:

6 times

Explanation:

1- getting the number of times required for one loaf:

We know that:

The loaf requires 0.75 of a cup of sugar

The cup can hold 0.25 cup of sugar

To know the number of times required to get the needed amount, we will simply do cross multiplication as follows:

1 time ................> 0.25 of a cup

?? times ..........> 0.75 of a cup

Number of times for one loaf = $(0.75*1)/(0.25)$ = 3 times

2- getting the number of times required for two loaves:

We have calculated that one loaf requires filling the measuring cup 3 times, this means that:

2 loaves would require filling the cup 2*3 = 6 times

Hope this helps :)
