Answer:
Either 6.5 or 3.60555127546
Step-by-step explanation:
Geometric mean is given by the formula :
[tex]\sqrt{a+b}[/tex] where a and b is the 2 numbers:
Substituting them in gives us :
[tex]\sqrt{3+10 }[/tex]
[tex]\sqrt{13}[/tex] = 3.60555127546
If that is wrong then it is given by the formula :
[tex]\frac{a+b}{2}[/tex]
Substituting these values gives us:
(3+10)/2 = 13/2 = 6.5

5 3.2 0.8
A solution to this equation to the nearest whole number is x = .
Does this equation have any other solutions?
The solution of the equation is approximately x = 4 and there are no other solutions
How to determine the solution of the equation?The equation is given as
0.1(2^x) = 4/x
Also, we have the table of values as one of the given parameters
Next, we check the table of values
From the table of values, we can see that:
The value of x is between x = 3 and x = 4
This is so because the values of the expressions 0.1(2^x) and 4/x are closest at these values
However, the value of x is closer to 4 than 3
This means that
x = 4 (approximately)
Hence, the solution of the equation is approximately x = 4 and there are no other solutions

((-6) + 7 - 3) x 2 divided by 4. Order of operations? I think the answer is -1.
Answer:

Step-by-step explanation:
The order of operation (PEMDAS) states that:
P - ParenthesisE - ExponentsM - MultiplicationD - DivisionA - AdditionS - SubtractionGiven expression:
[{(-6) + 7 - 3} x 2] ÷ 4We can see that "-6" is the integer that is inside the parenthesis "( )". Therefore, we can open the parenthesis "( )".
⇒ [{-6 + 7 - 3} x 2] ÷ 4Simplify the expression inside the curvy brackets "{ }" using PEMDAS.
⇒ [{1 - 3} x 2] ÷ 4 [PEMDAS]⇒ [{-2} x 2] ÷ 4 [PEMDAS]Now we can open the curvy brackets "{ }".
⇒ [-2 x 2] ÷ 4Simplify the expression inside the long brackets "[ ]" using PEMDAS.
⇒ [-4] ÷ 4Finally, open the long brackets "[ ]" and simplify the expression obtained.

How to determine the total parking area?From the complete question, the parking area consists of the following shapes and dimensions
Rectangle: 28 units by 40 unitsRectangle: 20 units by 25 unitsThe area of a rectangle is the product of its dimensions.
So, the area of the parking area is:

find the area of the shaded region. Use the formula A= pie r^2 to find the area of a circle
Answer:
(π6x+21π)m²
Step-by-step explanation:
Solution,
For small circle
radius(r)=x+2
Area(A1)=πr²
Area(A1)=π×(x+2)²
Area(A1)=π×(x²+4x+4)
Area(A1)=πx²+π4x+4π
For big circle
radius(r)=x+5
Area(A2)=πr²
Area(A2)=π×(x+5)²
Area(A2)=π×(x²+10x+25)
Area(A2)=πx²+π10x+25π
Again,
Area of shaded part=A2-A1
Area of shaded part=πx²+π10x+25π-(πx²+π4x+4π)
Area of shaded part=πx²+π10x+25π-πx²-π4x-4π
Area of shaded part=π6x+21π

Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°. Which of the following is a possible way to classify the triangle by side and angle measurements?
A. Obtuse and isosceles
B. Acute and scalene
C. Obtuse and equilateral
D. Acute and equilateral
Answer:
Acute and Scalene
Step-by-step explanation:
The measurments of the triangle are all almost equal and all the angles are less than 90 degrees, so all of them are acute angles. The scalene triangle has almost all equal sides.
The possible way to classify the triangle by side and angle measurements is,
⇒ Acute and scalene.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°.
Since, All the angles are less than 90 degree.
Hence, It shows the Acute angle.
Here, Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm.
Clearly, All the sides of triangle are not same in length.
Thus, It shows scalene.
Thus, The possible way to classify the triangle by side and angle measurements is,

¿Cuánto dinero tiene Pedro?Sabemos que:
María tiene 900 pesos.
Juan tiene el doble de la tercera parte de María, entonces:
J = (2/3)*$900 = $600
Juan tiene 600 pesos.
Finalmente, sabemos que la suma del dinero de Pedro y Juan es de $1,000 pesos, entonces tenemos que resolver la ecuación lineal:
P + J = $1,000
P + $600 = $1,000
P = $1,000 - $600 = $400
