Answer:

Step-by-step explanation:

The first thing you would want to do is to draw it out. Once you've drawn it out, you want to add the "imaginary lines" so the trapezoid will form into a rectangle. Then find out the area which is L * W. The area for the rectangle is 20.

Finally you want to take those imaginary pieces and find the area of those. Which would be three and then you want multiply by two since there is two of them. The last thing you need to do is subtract the six from 20.

Therefore the answer is 12.

A triangle has one angle that measures 17 degrees, one angle that measures 103 degrees, and one angle that measures

jeyben [28]

Answer:

The given triangle is an obtuse angled triangle.

Step-by-step explanation:

The measures of the given angle are:

∠1 = 17°, ∠2 = 103° and ∠3 = 60°.

OBTUSE ANGLE: The angle whose measure is more than 90° and less than 180° is an obtuse angle.

Now, Here, in the given triangle, ∠2 = 103° is an obtuse angle.

The triangle with a obtuse angle is known as an Obtuse Angled Triangle.

Hence, the given triangle is an obtuse angled triangle.

What is -5/6 divided by 9/10? A. -27/25 B. -4/3 C. -3/4 D. -25/27

kakasveta [241]

$-\frac{5}{6}$ ÷ $\frac{9}{10}$

First, apply the rule (easiest way if you have learned it): $a$ ÷ $\frac{b}{c} = a$ × $\frac{c}{b}$
$- \frac{5}{6}$ × $\frac{10}{9}$
Second, apply the last rule: $\frac{a}{b}$ × $\frac{c}{d} = \frac{ac}{bd}$
$- \frac{5*10}{6*9}$
Third, multiply 5 × 10 to get 50.
$- \frac{50}{6*9}$
Fourth, multiply 6 × 9 to get 54.
$-\frac{50}{54}$
Fifth, find the GCF of 50 and 54.
The GCF should be 2.
Sixth, divide the numerator by the GCF.
$50$ ÷ $2 = 25$
Seventh, divide the denominator by the GCF.
$54$ ÷ $2 = 27$
Eighth, now put 25 and 27 together to get the simplified fraction.
$- \frac{25}{27}$

Answer as fraction: $-\frac{25}{27}$
Answer as decimal: 0.9259

For the years between 2003 and 2010, the equation yˆ=937.98x+12,764.90 models the average cost of tuition of four-year colleges,

VMariaS [17]

Answer:

The best estimate for the average tuition cost in the year 2005 is $7,455

Step-by-step explanation:

In this question, we shall be using the predicted equation to predict the value of tuition in the year 2005.

The equation is y = 937.98x + 12,764.90

since x is the number of years after 2000 and we are looking at the average tuition cost in year 2005, thus, our x will be 2005-2000 = 5 years

Substituting this into the equation, we have;

y= 937.98(5) + 12,764.90

y = 7,454.8 which is 7,455 to the nearest dollars
