Use the integer tiles to evaluate the following expressions. 6 + 3 = 6 + (–4) = 6 + (–6) =

babunello [35]

Given:

The expressions are:

$6+3$

$6+(-4)$

$6+(-6)$

To find:

The value of given expression by using integer tiles.

Solution:

We have,

$6+3$

Here, both number are positive. When we add 6 and 3 positive integer tiles, we get 9 positive integer tiles as shown in the below figure. So,

$6+3=9$

Similarly,

$6+(-4)$

Here, 6 is positive and -4 is negative. It means we have 6 positive integer tiles and 4 negative integer tiles.

When we cancel the positive and negative integer tiles, we get 2 positive integer tiles as shown in the below figure. So,

$6+(-4)=2$

$6+(-6)$

Here, 6 is positive and -6 is negative. It means we have 6 positive integer tiles and 6 negative integer tiles.

When we cancel the positive and negative integer tiles, we get 0 integer tiles as shown in the below figure. So,

$6+(-6)=0$

Therefore, $6+3=9, 6+(-4)=2,6+(-6)=0$ .

4) How many license plates can be made using one letter

zalisa [80]

Answer:

2,600,000

Step-by-step explanation:

To determine the number of license plate that can be made with one letter and 5 digits;

Number of English alphabet = 26

Number of digits from 0 to 9 = 10

Each letter have 26 possible options and each digit have 10 possible options.

Number of license plate that can be made is;

N = 26 × 10^5

N = 2600000

A tower is 234 meters tall. Jaylon is looking up at the top of the tower and thinking it would be cool to string a zip line from

gizmo_the_mogwai [7]

Answer:

A length of 959.401 meters is needed for the zip line is needed to string it from the top of the tower to the platform.

Step-by-step explanation:

The geometrical representation of the statement is summarized in the figure below attached. The length of the line is represented by hypotenuse of the right triangle, whose value is calculated by the help of trigonometrical relations:

$\cos \alpha = \frac{h}{r}$ (1)

Where:

$\alpha$ - Angle formed between the zip line and the tower, measured in sexagesimal degrees.

$h$ - Vertical distance between the tower and the platform, measured in meters.

$r$ - Length of the zip line, measured in meters.

If we know that $\alpha = 76^{\circ}$ and $h = 232.1\,m$ , then the length of the zip line is:

$r = \frac{h}{\cos \alpha}$

$r = \frac{232.1\,m}{\cos 76^{\circ}}$

$r = 959.401\,m$

A length of 959.401 meters is needed for the zip line is needed to string it from the top of the tower to the platform.
