4 x 0.15 Is the problem I'm stuck onnnnn please help me it'll make me happy

kupik [55]

Answer:

0.6

Step-by-step explanation:

4 × 0.15

I can't show how to do it by typing, but in order to solve this you multiply 4 by each of those numbers and add them up together.

If done correctly, it should equal 0.6 or 0.60 (they are the same number).

Two sides of a triangle have the measures 7 and 10. Is it true or false that the range of possible measures for the third side i

adelina 88 [10]

Answer:

True

Step-by-step explanation:

We know that The triangle inequality states that the sum of the two sides of the triangle is always greater than the third side.

Here given that two sides of the triangle are 7 and 10

Let the third side be x

Here a = 7 , b = 10 , c = x

According to the triangle inequality

a + b > c

7 + 10 > x

x < 17

Also c + b > a

x + 10 > 7

x > -3

Also a + c > b

7 + x > 10

x > 3

Combining all the above results we get

3 < x < 17

All the values of x in the above region forms a triangle

Given x values lies in the region so they form a triangle

12,548:9( you can’t simplify this ratio)
62,547 divided by 7 = 8,935.28571
5127 divided by 25 = 205.08

Skills needed: Special Right Triangles

Step-by-step explanation:

1) We are given what is known as a right triangle. More specifically, this is a special right triangle. It is a:

30-60-90 triangle, which means it has a:

---> 30-degree angle

---> 60-degree angle

---> 90-degree (right) angle

There is an important property with the side lengths of this special right triangle.

2) The property is the following:

- Let's say the side opposite of the 30-degree angle is $b$ .

- The side opposite the 90-degree angle would be $2b$ .

- The side opposite the 60-degree angle would be $b * \sqrt3$

This property is useful for finding side lengths of the triangle.

3) In this problem, we are given the side opposite the 90-degree angle, which means we can divide by $2$ to solve for $b$ (side opposite 30° angle).

$4\sqrt{3} = 2b$ ---> This is the equation

$4\sqrt3 \div 2 = b$ --> We divide by 2 on both sides to isolate the variable.

$b = 2\sqrt3$ --> We evaluate it out, and get this to be our answer for $a$

Then, we can solve for the side opposite the 60-degree angle by multiplying $b$ by $\sqrt3$

---> $b*\sqrt3=2\sqrt3*\sqrt3 = 2*\sqrt3*\sqrt3=2*3=6$

$\sqrt3$ times itself would be 3, as multiplying by itself is squaring the square root, and removing it.

---> $a=6mm$ in the diagram.
