The perimeter of the triangle is 202cm. Using that find the value of x
Answer:
x = 13
Step-by-step explanation:
3x + 12 + 5x + 16 + 4x + 18 = 202
combine like terms
12x + 12 + 16 + 18 = 202
12x + 46 = 202
-46 -46
12x = 156
divide by 12
x = 13
Hope this helped! Have a nice rest of ur day! Plz mark as brainliest!!!
-Lil G
Add all the sides together (don´t forget parenthesis) Put the x´s with the x´s and the same with the other numbers. The subtract additional numbers from the total. The divide what left from the number in front of the x.
(3x + 12) + (5x + 16) + (4x + 18) = 202
8x + 28 + (4x + 18) = 202
12x + 46 = 202
- 46 -46
12x = 156
/12 /12
x = 13
∠A and angle B∠ are complementary angles. if m∠A=(4x+6)
∘
and m ∠B = (4x-4)∘
, then find the measure of∠A
Answer:
m∡A = 50°
Step-by-step explanation:
since they are complementary they must equal 90°
4x+6 + 4x-4 = 90
8x + 2 = 90
8x = 88
x = 11
∡A = 4(11)+6 = 44+6 = 50

The line l is tangent to the circle with equation x² + y2 = 169 at the point P.
By thinking about the radius or otherwise, determine the gradient of the line l.
Given:
The equation of a circle is
[tex]x^2+y^2=169[/tex]
A tangent line l to the circle touches the circle at point P(12,5).
To find:
The gradient of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Endpoints of the radius are O(0,0) and P(12,5). So, the slope of radius is
[tex]m_1=\dfrac{5-0}{12-0}[/tex]
[tex]m_1=\dfrac{5}{12}[/tex]
We know that, the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.
[tex]m\times m_1=-1[/tex]
[tex]m\times \dfrac{5}{12}=-1[/tex]
[tex]m=-\dfrac{12}{5}[/tex]
Therefore, the gradient or slope of the tangent line l is [tex]-\dfrac{12}{5}[/tex] .

Scientists studied the population of a species of bat in some caves in Missouri from 1983 to 2003. In 1983 there were 141,200 bats living in the caves. That number decreased by about 11% annually until 2003.
A. Identify the initial amount, the decay factor, and the decay rate
B. Write a function that models and number of that since 1983 then find the number of bats in 2003
Answer:
a)
The initial amount is 141,200.
The decay factor is 0.89, and the decay rate is of 0.11 = 11%.
b)
The function is [tex]y(t) = 141200(0.89)^t[/tex]
The number of bats in 2003 was of 13,729.
Step-by-step explanation:
Exponential decay function:
An exponential decay function has the following format:
[tex]y(t) = y(0)(1-r)^t[/tex]
In which y(0) is the initial value, 1 - r is the decay factor and r is the decay rate, as a decimal.
A. Identify the initial amount, the decay factor, and the decay rate
In 1983 there were 141,200 bats living in the caves, which means that the initial amount is 141,200.
That number decreased by about 11% annually until 2003 means that the decay factor is 1 - 0.11 = 0.89 and the decay rate is 0.11 = 11%.
B. Write a function that models and number of that since 1983 then find the number of bats in 2003
With the data found in question A, we have that:
[tex]y(t) = y(0)(1-r)^t[/tex]
[tex]y(t) = 141200(1-0.11)^t[/tex]
[tex]y(t) = 141200(0.89)^t[/tex]
The function is [tex]y(t) = 141200(0.89)^t[/tex]
Number in 2003
2003 is 2003 - 1983 = 20 years after 1983, so this is y(20).
[tex]y(20) = 141200(0.89)^{20} = 13729[/tex]
The number of bats in 2003 was of 13,729.

The volume of a rectangular prism can be found by multiplying the three side lengths. A bookcase in the shape of a rectangular prism has dimensions (b+8) ft, b ft, and (b+3) ft. Find the volume of the bookcase
Answer:
(b³+11b²+24)ft³
Step-by-step explanation:
Volume of the rectangular prism = Length * Width * Height
Given the dimension
Length = b+8 ft
Width = b ft
Height = (b+3)ft
Volume of the rectangular prism = b(b+8)(b+3)
Volume of the rectangular prism = b(b^2+3b+8b+24)
Volume of the rectangular prism = b(b^2+11b+24)
Volume of the rectangular prism = b(b^2)+b(11b)+1(24)
Volume of the rectangular prism = b^3+11b^2+24
Hence the Volume of the rectangular prism is (b³+11b²+24)ft³

Answer:
4x^3+2x^2+2x
Step-by-step explanation:
The difference of the two polynomials, is: f(x) - g(x) = 4x³ + 2x² + 2x
How to Subtract Polynomials?To subtract one polynomial from another, take like terms together.
Given the polynomials:
f(x) = 9x³ + 2x² - 5x + 4 and g(x) = 5x³ - 7x + 4
Find f(x) - g(x):
(9x³ + 2x² - 5x + 4 ) - (5x³ - 7x + 4)
Open the bracket
9x³ + 2x² - 5x + 4 - 5x³ + 7x - 4
Combine like terms together
4x³ + 2x² + 2x
Therefore, the subtraction of the two polynomials, is: f(x) - g(x) = 4x³ + 2x² + 2x

Select the quadrant in which the terminal side of the angle falls.
210° terminates in quadrant
390° terminates in quadrant
Answer:
The answer is below
Step-by-step explanation:
Select the quadrant in which the terminal side of the angle falls.
210° terminates in quadrant
-150° terminates in quadrant
390° terminates in quadrant
Solution:
The x and y axis divides the cartesian plane into four equal parts known as the four quadrants.
Angles between 0° and 90° are in the first quadrant, angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant while angles between 270° and 360° are in the fourth quadrant.
a) Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
b) -150° = 360 - 150 = 210°. Since 210 degrees is between 180° and 270°, hence it terminates in the third quadrant.
c) 390° = 390° - 360° = 30°.
Since 30 degrees is between 0° and 90°, hence it terminates in the first quadrant.
