If tiffany drove 21 miles using 7 gallons of gas, how many miles did she drive per gallon.?​

Answer:

The number of x-intercepts of the function are:

Two(2)

Step-by-Step explanation:

The domain of a quadratic function is all real numbers and the range is y ≤ 2.

i.e. the graph of this quadratic polynomial will be a downward parabola whose vertex has y-coordinates less than or equal to 2.

Also we know that any upward or downward facing parabola have two x-intercepts i.e. the  parabola crosses the x-axis at two points i.e. the y-coordinates of those two points are zero.

Hence, the number of x-intercepts of the function is:

Two(2)

Answer:

2 just took it :)

Step-by-step explanation:

The equivalent of the weight that has a measure of 60 ounces in kilogram is 4.54 kg

How to determine the weight in kilogram

from the question, we have the following parameters that can be used in our computation:

Weight = 160 ounces

When converted to kilogram, we divide the weight by 35.274

Using the above as a guide, we have the following:

Weight = 160/35.274 kg

Evaluate

Weight = 4.54 kg

Hence, the weight in kilogram is 4.54 kg

Answer:

Whether her conversion is correct or not, you can just base it on the true answer. For this problem, we apply the technique of dimensional analysis. You can like units if they both appear in the numerator and the denominator side. The solution is as follows:

Mass in ounces = 3 kg * (1,000 g/ 1 kg) * (1 ounce/28.35 g) = 105.82 ounces
