Answer:

y = 7.

y = -11.

y = -1.

Step-by-step explanation:

All the verticals on the coordinate plane are either y-axis or parallel to the y-axis.

And the equations of all the vertical straight lines on the coordinate plane is given by y = c ........... (1), where c is any real constant.

Now, putting c = 0 we will get the equation of y-axis i.e. y = 0.

Therefore, y = 7 is the equation of a vertical passing through (3,7) points.

The equation of the vertical passing through (30,-11) is y = -11.

And the equation of the vertical passing through (0,-1) is y = -1. (Answer)

2000 soldiers stand in a row. Beginning from the left, each soldier calls out a number, 1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3, and

Cloud [144]

Answer:

The number of soldiers that call out a number 3 is 666 soldiers

Step-by-step explanation:

The parameters given are;

Number of soldiers = 2000

Soldiers calling from the left = 1, 2, 3,.....

Soldiers calling from the right = 1, 2, 3,.....

Therefore, since the number soldiers calling out the number 3 are 1 in 3 from the left and 1 in 3 from the right, we split the soldiers into 2 groups of 1000, with one group calling from left and the other group calling from the right;

The number of 3s in called out in the first group from the left is therefore;

1000/3 = 333.33 which is 333 soldiers or from the 3rd soldier to the 999th soldier

Similarly the number of 3s called out from the second group = 333

Hence the total number of soldiers that call out a number 3 = 333 + 333 = 666 soldiers.

When making a book cover, Anwar adds an additional 20 square inches to the surface area to allow for overlap. How many square in

e-lub [12.9K]

Answer:

234 square inches

Step-by-step explanation:

We are given that

Length of book, l=11 in

Width of book, w=8 in

Height of book, h=1in

Additional area required to overlap=20 square inches

We have to find how many square inches of paper to make cover of one book.

We know that surface area of cuboid

$S=2(lb+bh+hl)$

Using the formula

Surface area of book

$S=2(11\times 8+8\times 1+1\times 11)$

$S=214 in^2$

Total paper used to make cover of one book

=Surface area of book +additional surface area

= $214+20$

$=234in^2$

Hence, Anwar will use paper to make cover of one book=234 square inches

Given a battery rated at 350 ampere-hours how many hours will the battery be able to provide 7 amperes

coldgirl [10]

From the division computed, it should be noted that the number of hours that the battery will be able to provide 7 amperes will be 50 hours.

The information given is about the division of numbers. It was stated that the battery is rated at 350 ampere-hours.

The number of hours that it will be able to provide 7 amperes will be:

= 350 / 7

= 50 hours.
