Step-by-step explanation:
A store advertises 15% off an item that regularly sells for $300. what is the sale item? how is a 15% discount similar to a 15% decrease? Explain.
Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.
Find the value of x that will make a||b
The location of each angle make them vertical angles. For the lines to be parallel the two angles need to be equal to each other.
5x + 20 = 3x + 60
Subtract 3x from both sides:
2x + 20 = 60
Subtract 20 from both sides:
2x = 40
Divide both sides by 2:
X = 20

where the area of the base is 6.8\text{ m}^26.8 m 2 and the height of the pyramid is 8.6\text{ m}8.6 m. Round your answer to the nearest tenth of a cubic meter.
r = radius h = height s = slant height V = volume L = lateral surface area B = base surface area A = total surface area π = pi = 3.14159 √ = square root
The Volume of pyramid is 19.5 [tex]m^{3}[/tex].
What is pyramid?A pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apx. Each base edge and apx form a triangle, called a lateral face.
What is volume of pyramid?The volume of a pyramid refers to the space enclosed between its faces.
Volume of pyramid = (1/3) (Base area * height of pyramid )
According to the question
Area of the base = 6.8 [tex]m^{2}[/tex]
Height of the pyramid = 8.6 m
now,
using the formula of Volume of pyramid
Volume of pyramid = (1/3) (Base area * height of pyramid )
substituting the values
Volume of pyramid = (1/3) ( 6.8 * 8.6 )
= 19.49 [tex]m^{3}[/tex]
Rounding off to nearest tenth of a cubic meter
Volume of pyramid = 19.5 [tex]m^{3}[/tex]
Hence, the Volume of pyramid is 19.5 [tex]m^{3}[/tex]

Answer:
16
Step-by-step explanation:
radius is 1/2 of diameter
Answer:
16 units
Step-by-step explanation:
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units.

A root is equivalent to a fractional power. A square root is a 1/2 power. A cube root is a 1/3 power. The index of the root is the denominator of the fraction.
Of course the usual rules of exponents apply in evaluating an expression.
(a^b)^c = a^(bc)

The graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
What is a circle?A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point. A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given equation of the graph is f(x + 5)² + (y – 10)² < 169. When we plot the equation we get the circle having an inside shaded part. The coordinates of the circle are (5,-10).
Therefore, the graph of (x + 5)² + (y – 10)² < 169. The circle with centre at (5, –10), shading inside the circle. The correct option is B.
