Answer:
Step-by-step explanation:
So let the angles be 2x,3x,5x
∠A + ∠B + ∠C + ∠C = 360
[Sum of all the angles of a quadrilateral ]
⇒2x+3x+5x+130=360
⇒10x = 360 -130
⇒x = 23
The angles are ,
∠A = 2x = 2×23 = 46
∠B = 3x = 3×23 = 69
∠C = 5x = 5×23=115
Let the angles be 2x,3x and 5x
We know that 2x+3x+5x+130=360
10x+130=360
10x=230
Therefore x=23°
2x=46°
3x=69°
5x=115°

Find the surface area of the pyramid. The side lengths of the base are equal. Square pyramid with base edge of 12 centimeters, and a slant height measuring 17 centimeters, on a triangular face. The surface area is square centimeters.
Answer:
the surface area of the square pyramid is 576.66 cm^2
Step-by-step explanation:
The computation of the surface area of square pyramid is given below:
A = a^2 + 2a × √a^2 ÷ √4 + √h^2
where
a = 12 cm
h = 17 cm
Now put the value of a and h in the above formula
= 12^2 + 2(12) × √12^2 ÷ √4 + √17^2
= 576.66 cm^2
hence, the surface area of the square pyramid is 576.66 cm^2

Step-by-step explanation:
Think about some easy coordinates. If you plug in x=0, the y coordinate must be 2, eliminating B.
Next, as x becomes larger and larger, the y value decreases. This means that the value inside the bracket must be less than 1. If it is greater than 1, the y value would increase as x increased.
To illustrate, 2 < 2^2 < 2^3 < 2^4
However, 0.5 > 0.5^2 > 0.5^3
You can check this in your calculator if you need to.

What is the volume of a sphere with a diameter of 4.9 cm, rounded to the nearest
tenth of a cubic centimeter?
Answer:
492.87cm^3
Step-by-step explanation:
Given data
Diameter= 4.9cm
The expression for the volume is
V= 4/3 πr^3
Substitute
V= 4/3*3.142*4.9^3
V= 4/3*3.142*117.649
V=1478.612632 /3
V=492.87 cm^3
Hence the volume is 492.87cm^3

HELP!!!!!Which property can you apply to Hayley's expression to show that it is equivalent to Gretchen's expression?
Complete question :
Gretchen and her friend Hayley bought three bags of apples and three bunches of bananas from the fruit vendor. Gretchen and Hayley want to find the total number of pieces of fruit that they bought. Gretchen thinks she should multiply 3 by the number of apples in each bag, x, and add it to 3 times the number of bananas in each bunch, y, to find the total number of pieces of fruit. Hayley thinks Gretchen should add the number of apples in each bag, x, to the number of bananas in each bunch, y, and then multiply that sum by 3.
Which property can you apply to Hayley’s expression to show that it is equivalent to Gretchen’s expression?
Answer:
The distributive property of multiplication
Step-by-step explanation:
Number of apples per bag = x
Number of bananas per bunch = y
3 each of bananas and apples were bought
Expression to obtain the total fruits bought :
Gretchen's expression :
3x + 3y
Haley's expression :
3(x + y)
According to the distributive property :
Haley's equation :
3(x + y)
(3 * x) + (3 * y)
3x + 3y
Hence, Gretchen's expression = Haley's expression by the distributive property of multiplication.

if the vertex of a parabola is (0, -4), what is the axis of symmetry?
If the vertex of a parabola is (0, -4). The equation of the axis of symmetry for this parabola is x = 0.
How to convert the given equation to vertex form?We first take out the coefficient of x squared, and then inside the bracket, we try to make a perfect square-like situation.
For parabolas, its axis of symmetry always goes through the vertex of the parabola.
In other words, the axis of symmetry is a vertical line that goes through the x-coordinate of the vertex.
Now, if the vertex of a parabola is (0, -4) which is at x = 0, y = -4.
Thus, the vertical line that goes through the coordinate of the vertex would be x = 0
Thus, the equation of the axis of symmetry for this parabola is x = 0.
