Answer:

The second equation which is a(b+c) = ab + ac.

Step-by-step explanation:

Remember that when you think of the word distribute, you want to see a variable or a number behind the parentheses. The fourth equation would not work despite there being distributive in which it will give you abc. The second equation is a great example of what a distributive property problem may do.

A company makes traffic signs one of those signs can be modeled by an equilateral triangle with the perimeter of 144 inches the

barxatty [35]

Answer:

The height of the larger traffic signs is 51.96 inches

Step-by-step explanation:

Given that initially, A company makes traffic signs of an equilateral triangle with the perimeter of 144 inches

Now, A company makes similar traffic signs of perimeter 1.25 of original

New perimeter will be 1.25x144=180 inches

Let triangle ABC be a larger triangle with 180inches of the perimeter.

It is given that the triangle is an equilateral triangle,

Therefore, Side AB=BC=AC

The perimeter of a triangle ABC is

AB+BC+AC=180

3AB=180

AB=60 inches

Figure show that triangle ABC and AD is the height of the triangle.

Since, the triangle ABC is an equilateral triangle,

AD is the perpendicular bisector of BC

so that,

BD=DC and Angle ADB=90

In right triangle ADB,

Angle D =90 and Angle B =60

Side BD=60/2=30 inches and AB=60 inches

Using Pythagoras theorem,

$AD^{2} +BD^{2} =AC^{2}$

$(AD)^{2} +(30)^{2} =60^{2}$

$(AD)^{2} =60^{2}-(30)^{2}$

AD=51.96 inches

Thus, The height of the larger traffic signs is 51.96 inches

What is C in the triangle <br> C=

Alla [95]

Answer:

C = 13

Step-by-step explanation:

$A^{2}$ + $B^{2}$ = $C^{2}$

$5^{2}$ + $12^{2}$ = 169

$\sqrt{169}$ = 13

Hello! For these kinds of problems, the formula for finding the principal is I / rt. That means, divide the simple interest by the rate and time (rate should be in decimal form). In order to find simple interest, just do prt, which means multiply the principal (initial amount) by the rate (simple interest rate, in decimal form) by the amount of time (could be in months or years). With that being said, if you solve it correctly, here are your answers:

Principal: $14,181
Interest rate: 10%
Time: 4 years
Simple Interest: $5,672.40

Principal: $83,079
Interest rate: 9%
Time: 2 years
Simple Interest: $14,954.22

Principal: $659,379.96
Interest rate: 11.7%
Time: 28 months
Simple Interest: $179,753.57

Principal: $18,936
Interest Rate: 2.41%
Time: 3 Months
Simple Interest: $114.09

Note: If the time is in months, be sure to convert it into a decimal and multiply. If a decimal repeats, just convert it to the nearest hundredth.
