Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know:</h3>
- linear equation
- linear equation word problems
- PEMDAS
<h3>tips and formulas:</h3>
<h3>let's solve:</h3>
all we need to care about the middle condition which is
<h3>the new test score is 15 points more than the original score</h3>
given that
original score is x
New score is y
if you pay attention to the given condition
we can find it same as linear equation
therefore
according to the question
the equation is
<h2>y=x+15</h2>
Answer:
82.4 ft^3
Step-by-step explanation:
Diameter=5.4ft
Radius=diameter/2
=5.4ft/2
=2.7ft
π=3.14
Volume of a sphere=4/3πr^3
=4/3×3.14×2.7^3
=4/3×3.14×19.683
=4/3×61.80462
=247.21848/3
=82.40616
Approximately
82.4 ft^3
The statements that I agree with, with respect to a parallelogram are:
- A parallelogram has six sides.
- Opposite sides of a parallelogram are parallel.
- All angles of a parallelogram have the same measure.
- All sides of a parallelogram have the same length.
<h3>What is a
parallelogram?</h3>
A parallelogram can be described as the quadrilateral that do contains two pairs with respect to their parallel sides.
It should be noted that the sides that can be found in the parallelogram are usually of the same length and there the sides that can be attributed to a parallelogram is usually 6.
Therefore, the option 1,2,4,5 are correct.
