Each year for 8 years, the Williams family visited 6 different states on vacation. How many more states do they need to visit be

shusha [124]

Answer: 2 states

Step-by-step explanation:

Every year for 8 years, the Williams family visited 6 different states on vacation. This means for 8 years, the family have visited:

= 8 × 6

= 48 states

Since there are 50 states in total, that means we will subtract 48 from 50. This equals :

50 - 48 = 2 states.

They've 2 states left to visit

What two numbers add to equal ten and multiplies to equal negative seven?

lawyer [7]

Okay ShallBeTheLast, what we will do will involve a lot of simple plug and play kind of actions.
To start we must notice one number must be negative and the other should be positive, because the multiplied number is a negative.

Next, lets multiply number that have a sum of 10 (keep in mind one has to be negative and the other has to be positive).

-1 * 10 = -10 false
-2 * 12 = -24 false
-3 * 13 = -39 false
notice that no number working and it's only getting farther away.
There is no solution for this that involves to integers.

I think you might of wrote the question backwards.
If that is the case we would run numbers like.....
-1 * (-6) = 7 false
-2 * (-5) = 10 true!!!!

-2 and -5 would work

An architect's sketch of plans for the front of a garage in the shape of pentagon is shown below. What is the approximate perime

Vesna [10]

Using it's concept, it is found that the approximate perimeter of the front of the garage is:

A. about 36 ft.

<h3>What is the perimeter of a figure?</h3>

The perimeter of a figure is given by the total length of it's boundary.

In this problem, we have that:

The bottom boundary has length of 10 units.

The two lateral boundaries have lengths of 7 units.

There are two top boundaries, which are the hypotenuses of a right triangle with legs 3 and 5, hence:

$t = \sqrt{3^2 + 5^2} = 5.83$

Hence the perimeter of the figure is:

P = 10 + 2 x 7 + 2 x 5.83 = 35.66.

Rounding, it is of about 36 ft, hence option A is correct.

24 red flowers and 18 white flowers will be equally divided into groups. Find the greatest number of groups that can be created

mariarad [96]

Given:

The number of red flowers =24

The number of white flowers = 18

As flowers divided equally.

$\begin{gathered} 24=4\times6 \\ 18=3\times6 \end{gathered}$

The HCF ( highest common factor) of 24 and 18 is 6.

The largest number of group that can be created is 6.
