Firdavs [7]

Answer:

Part 4) Right triangle

Part 5) Kite

Step-by-step explanation:

Part 4) What kind of triangle is made by connecting the points A(0, –6), B(3, –6), and C(3, –2)?

Using a graphing tool

see the attached figure N $1$

The triangle of the figure is not equilateral------> The triangle does not have three equal sides

The triangle of the figure is a right triangle------>The triangle has an angle of $90\°$

The triangle of the figure is not isosceles------> The triangle does not have two equal sides

The triangle of the figure is not a right and isosceles

Part 5) What type of quadrilateral is formed by connecting the points $(0, 9), (3, 6), (0, 1), and (-3, 6)$ ?

Using a graphing tool

see the attached figure N $2$

The figure is not a rhombus------> All sides are not congruent

The figure is not a trapezoid-----> has not parallel sides

The figure is a kite------> Two disjoint pairs of consecutive sides are congruent and the diagonals meet at a right angle

A waitress works 1.75 hours less in the afternoon than in the evening. If she works 5 1/8

gayaneshka [121]

Let $x$ be the number of hours that the waitress works in the evening.

We know for our problem that she works $5 \frac{1}{8}$ in the afternoon and that she works <span>1.75 hours less in the afternoon than in the evening, so:
</span> $x=5 \frac{1}{8} -1.75$
<span>Since </span> $\frac{1}{8} =0.125$ , we can rewrite our expression:
$x=5.125-1.75$
$x=3.375$

We can conclude that she works 3.375 hours in the evening, or expressed as a mixed fraction: $3 \frac{3}{8}$ hours.
