Answer:
Without solving, the solution is greater than 21. The can be proven because a fraction of x is equal to 21, therefore x cannot be less than 21.
Step-by-step explanation:
Answer:
If the sign of the leading coefficient is positive, the parabola opens upward. If it's negative, the parabola opens downward.
Step-by-step explanation:
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50
Answer:
Feet Above Sea Level
Step-by-step explanation:
A benchmark is a term in Surveying and Geo informatics, that describes a point of reference established at a known elevation which serves as basis in which other elevation or topographical point can be measured.
Therefore, when determining the benchmark, it's height is calculated relative to the vertical datum of the area, typically mean sea level, which is then recorded in FEET ABOVE SEA LEVEL.
Hence, Benchmarks measurements refer to FEET ABOVE SEA LEVEL.
If the volume of each brick will be 64 cubic centimeters. Then the mass of each brick will be 192 grams.
<h3>What is density?</h3>
Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
A construction company needs to transport 500 bricks. The dimensions of each brick are 2 cm by 4 cm by 8 cm.
The density of each brick is 3 g/cm³.
Then the mass of each brick will be
The volume of each brick will be
V = 2 x 4 x 8
V = 64 cm³
Then the mass will be
m = 3 x 64
m = 192 gram
