BigorU [14]3 years ago
6 0

Answer:

\dfrac{\$160}{6~calculators}

\dfrac{\$26.67}{calculator}

Step-by-step explanation:

The rate for the 6 calculators is

\dfrac{\$160}{6~calculators}

To find the unit rate, divide 160 by 6.

The unit rate is

\dfrac{\$26.67}{calculator}

9x1/10+6x1/100+4x1/1,000 how can this measurement be written as a decimal
omeli [17]
The above equation can be written as
\frac{9}{10}  +  \frac{6}{100}  +  \frac{4}{1000}
Then make all the denominators the same
\frac{900}{1000}  +  \frac{60}{1000}  +  \frac{4}{1000}  =  \frac{964}{1000}
964/1000 = 0.964

Identify the domain and range of each function
RSB [31]

Answer: A) Domain: All real numbers , Range: All real numbers

Step-by-step explanation: Since the line of the graph continued to infinity, the answer for both domain (goes from Left to right) and range (goes up to down) would be all real numbers

Trigonometry
Natasha_Volkova [10]

Answer:

Step-by-step explanation:

For a triangle the area is

A=\frac{1}{2}bh

If our triangle is isosceles and the 2 congruent sides each measure 4 and they include an angle of 40 degrees, let's say that the vertex angle is 40 and the sides that are not the base each measure 4.  If we drop an altitude from the vertex to the base, we cut the triangle into 2 right triangles, with the vertex angle being 20 degrees and the hypotenuse being 4.  To find the base, then, which is opposite the angle, we use the sin ratio:

sin(20)=\frac{b}{4} and

4sin(20) = b so

b = 1.368

But we need the whole base, and that is only half of it.  So

2b = 2.736

To find the height, which is adjacent to the angle, we use the cos ratio:

cos(20)=\frac{h}{4} and

4cos(20) = h so

h = 3.759

Now we have enough info to find the area of the triangle using the triangle area formula from above:

A=\frac{1}{2}(2.736)(3.759) and

A = 5 meters squared.
