Answer:

6 < third side < 14

Third side must be greater than 6 and less than 14

Step-by-step explanation:

A triangle can be formed from 2 sides of any length.

The third side must be longer than the difference of the other 2 sides and

the third side must be less than the sum of the other 2 sides.

I had a quiz with the same question and got an A

Hope this helps! :)

3. Bob the Builder wants to earn an annual rate of 10% on his investments,

mamaluj [8]

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

$T = E + P$

In this question:

Rate of 10%, so I = 0.1.

9 months, so $t = \frac{9}{12} = 0.75$

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

$T = E + P$

$3000 = E + P$

$E = 3000 - P$

Then

$E = P*I*t$

$3000 - P = P*0.1*0.75$

$1.075P = 3000$

$P = \frac{3000}{1.075}$

$P = 2790.7$

He should pay $2,790.7.

Which type of transformation maps trapezoid PQRS onto trapezoid P'Q'R'S'? reflection rotation translation dilation

Keith_Richards [23]

Answer:

Dilation.

Step-by-step explanation:

From the given picture , it can be seen that the size of trapezoid P'Q'R'S' is decreased from trapezoid PQRS .

Reflection , rotation and translation are rigid motions that produces congruent images and do not change the size of the shapes.

But dilation is not a rigid motion because it changes the size of the shape by using a scale factor.

Hence, the transformation maps trapezoid PQRS onto trapezoid P'Q'R'S' is "Dilation".

Can someone please help I really need these points

spayn [35]

Given:

Two chords intersect each other inside the circle.

To find:

The value of x.

Solution:

According to intersecting chords theorem, if two chords intersect each other inside the circle, then the product of two segments of one chord is equal to the product of two segments of second chord.

In the given circle,

$AE\times CE=BE\times DE$

$(3x-11)\times (5x-4)=(x+2)\times (-x+17)$

$15x^2-12x-55x+44=-x^2+17x-2x+34$

$15x^2-67x+44+x^2-15x-34=0$

$16x^2-82x+10=0$

Divide both sides by 2.

$8x^2-41x+5=0$

Splitting the middle term, we get

$8x^2-40x-x+5=0$

$8x(x-5)-1(x-5)=0$

$(8x-1)(x-5)=0$

Using zero product property, we get

$(8x-1)=0$ or $(x-5)=0$

$x=\dfrac{1}{8}$ or $x=5$

For $x=\dfrac{1}{8}$ , the side AE is negative. So, $x=\dfrac{1}{8}$ is not possible.

Therefore, the required solution is $x=5$ .
