Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!
Hi There! :)
The length of s is 2/3 the length of t. If s has an area of 368 cm squared find the perimeter of the figure
<span>920</span>
If we divide 360 by the number of sides, 16, we will get the measure of one of the 16 central angles. 360/16 = 22.5. The vertex angle of one of the triangles that makes up this 16-gon is 22.5. That means that each of the base angles measure 78.75. If we put 2 of these triangles next to each other, 2 sides touching, the bases of both those triangles meet to form an interior angle. Two base angles of 78.75 together form the interior angle: 78.75+78.75 = 157.5. An interior angle measures 157.5. The exterior angle then has to measure 180-157.5 which is 22.5, same as the vertex angle of 1 of the triangles that make up this 16-gon.
Answer:
Dale will reach his goal at an annual rate of 11.83%.
Step-by-step explanation:
The formula for continuos compounding is given by:
In which A is the amount after t years, P is the principal(initial amount) and r is the annual rate.
Dale has 2000 dollars to invest.
This means that
He has a goal to have 5800 in this invest ment in 9 years.
So
At what annual rate compounded continuously will Dale reach his goal?
This is r.
Dale will reach his goal at an annual rate of 11.83%.
2.5% Would be your answer.
Does this help any?
