Answer:

Step-by-step explanation:

7=42 is 7*6

6=30 is 6*5

5=20 is 5*4; it's multiplied by the number below it, so 3 will be 3*2

3 = 6

Step-by-step explanation:

Given: 7 = 42, 6 = 30, 5 = 20

7 (x 6) = 42

6 (x 5) = 30

5 (x 4) = 20

Follow the pattern

4 (x 3) = 12

3 (x 2) = 6

3 = 6

Answer:

Step-by-step explanation:

$\frac{5}{5} + 6 = 1 + 6$

To solve this you just have to replace the letters with the corresponding numbers. 5/5 = 1 and 1+6 = 7

So your answer is 7!

(2, 7) and (-6, -2) find the distance between each pair of points

yaroslaw [1]

Answer:

$\sqrt{145}$

Step-by-step explanation:

Hi there!

We are given the points (2, 7) and (-6, -2). We want to find the distance between them. To do that, we can use the distance formula

The distance formula is given as $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have 2 points, which is what we need to find the distance, but let's label their values to avoid any confusion

$x_1=2\\y_1=7\\x_2=-6\\y_2=-2$

Now substitute those values into the formula:

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\sqrt{(-6-2)^2+(-2-7)^2}$

Simplify the values under the radical:

$\sqrt{(-8)^2+(-9)^2}$

Raise to the second power:

$\sqrt{64+81}$

Add the numbers under the radical together

$\sqrt{145}$

The answer can be left as that, as the radical cannot be simplified.

Hope this helps!

Mr brown shares with the class that 70%of the students got a A on the English vocabulary quiz if mr brown has 100 students creat

Harrizon [31]

70% of 100 is 70 students. Unfortunately I can not make a model for you but here's an idea: Draw a large circle. Next, draw a line halfway down the circle, and halfwar down draw another line to the right, this making it look like three fourths. Then, color the larger space in one color and the other smaller space that looks like a small slice of pie in another color. On the larger piece write "70% who got an A" and on the smaller write "30% who didn't get an A" At the bottom you can write 70 students out of 100 got an A on the test.
