The length of a side and the corresponding height of a triangle are (x+3) cm and (2x-5) cm respectively. Given that thr area of the triangle is 20 cm^2, find the value of x.
Answer: 5
Step-by-step explanation:
Given
The length of a side is [tex]x+3\ cm[/tex]
The height of a triangle is [tex]2x-5\ cm[/tex]
Area of triangle is [tex]20\ cm^2[/tex]
Area of triangle is given by
[tex]\Rightarrow A=\dfrac{1}{2}\times \text{base}\times \text{height}[/tex]
[tex]\Rightarrow A=\dfrac{1}{2}\times (x+3)\times (2x-5)\\\\\Rightarrow 40=(x+3)\times (2x-5)\\\Rightarrow 2x^2+x-55=0\\\\\Rightarrow x=\dfrac{-1\pm \sqrt{1^2-4(2)(-55)}}{2(2)}\\\\\Rightarrow x=\dfrac{-1\pm 21}{4}\\\\\Rightarrow x=-5.5,5[/tex]
Neglecting negative value
Therefore, the value of x is 5.

What is the volume of this sphere?
Use a = 3.14 and round your answer to the nearest hundredth.
8 mm
cubic millimeters
Answer:
Volume = 2,143.57 mm³
Step-by-step explanation:
Given:
radius (r) = 8 mm
π = 3.14
Required:
Volume of the sphere
Solution:
Volume of the sphere = ⁴/3πr³
Plug in the values
Volume = ⁴/3 × 3.14 × 8³
= ⁴/3 × 3.14 × 512
= 6,430.72/3
Volume = 2,143.57333
Volume = 2,143.57 mm³ (nearest hundredth)

What are the zeros of the quadratic function?
y = x^2 - 2x - 15
Answer:
[tex]x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}[/tex]
Step-by-step explanation:
[tex]-> 0=2x^2-2x-15[/tex]
-zeros means the solution aka x intercept, meaning y=0
[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:2\left(-15\right)}}{2\cdot \:2}[/tex]
=> according to quadratic formula
[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
where [tex]ax^2+bx+c=0[/tex]
=> [tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{31}}{2\cdot \:2}[/tex]
simplify
[tex]x_1=\frac{-\left(-2\right)+2\sqrt{31}}{2\cdot \:2},\:x_2=\frac{-\left(-2\right)-2\sqrt{31}}{2\cdot \:2}[/tex]
[tex]x=\frac{1+\sqrt{31}}{2},\:x=\frac{1-\sqrt{31}}{2}[/tex]

Answer:
Multiply by -2
Step-by-step explanation:
Additive inverse essentially means the counterpart that negates a number. Then, elimination can be used. In this case, the easiest change would be with the terms -4y in the first equation, and -2y in the second equation, since 2 is a factor of 4. So,
3x - 4y = -5
5x - 2y = -6
The goal here is to cancel out the -4y.
(5x - 2y)(-2) = (-6)(-2)
-10 + 4y = 12
3x - 4y = -5
Now it works.

Grace has $15 in her bank account. She starts
saving $5 each week. Jose has $5 in his account
and is saving $10 each week. What is the slope of the line that represents Grace's bank account?
Answer:
[tex]\frac{5}{1}[/tex] or 5
Step-by-step explanation:
Using the data provided we would create the following equation to calculate Grace's bank account using the variable x to represent the number of weeks.
f(x) = 5x + 15
The slope of a function in such a function would be the value of that is being multiplied by x. The numerator would be the numberof units it is rising in a graph while the denominator represents the number of units it is moving to the right. Since in this scenario, the number is a whole number (5) the denominator is automatically 1. Meaning that the slope is 5 units up for every 1 unit to the right.

3) Find the area of the composite figure.
Answer:
356.93sq. cm
Step-by-step explanation:
Area of the composite figure = Area of rectangle + Area of semicircle
Area of rectangle = length * wiidth
Area of rectangle = 14cm * 20cm
Area of rectangle = 280 sq. cm
Area of semicircle = πr²/2
Area of semicircle = 3.14(7²)/2
Area of semicircle = 3.14 * 49/2
Area of semicircle = 76.93 sq. cm
Hence the area of the figure = 280 + 76.93
Hence the area of the figure = 356.93sq. cm
Find the rate percent per annum at which birr 380 earns birr 128.25 in 7 years and 6 months?
Answer:
A = $4,035.13
Step-by-step explanation:
Given: 380 earns, 128.25 in 7 years and 6 months
To find: The rate percent per annum
Formula: [tex]A = P(1 + rt)[/tex]
Solution: I = A - P = $3,655.13
Equation:
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 128.25%/100 = 1.2825 per year.
Solving our equation:
A = 380(1 + (1.2825 × 7.5)) = 4035.125
A = $4,035.13
The total amount accrued, principal plus interest, from simple interest on a principal of $380.00 at a rate of 128.25% per year for 7.5 years is $4,035.13.
