Answer:

Domain: {-6, -2, -1, 1, 3, 6}

Range: {-6, -2, -1, 0, 3}

Step-by-step explanation:

to find the domain of a function, you look at all the possible x-values. this means you look at all the points, and see what their x-values are.

for example, the first point on the left is at (-6, -1). this means that -6 is in the domain. continue doing this for all the points, and you get {-6, -2, -1, 1, 3, 6}

to find the range of a function, it's just like domain but with y-values.

for example, for the leftmost point, it's at (-6, -1) so -1 is part of the range. continuing this with all the points, you get {-6, -2, -1, 0, 3}

Number 18 and 20 thank you

Afina-wow [57]

18.) The area of one of the triangles would be half of the area of the parallelogram, because the two triangles are congruent.

20.) The formula for the area of a parallelogram is:
A = b • h

110.5 = 13h

110.5 / 13 = 8.5

110.5 = 13 • 8.5

And because this is a measurement of the height, not the area, it is just meters (m)

So, the full answer is 8.5 m

I hope this helps!

India can paint 3 1/5 walls in one day. How many walls can she paint in 5 1/2 days?

sladkih [1.3K]

Change the mixed numbers into fractions.

$3 \frac{1}{5}$
$3 * 5 = 15$
$15 + 1 = 16$
$3 \frac{1}{5} = \frac{16}{5}$

$5 \frac{1}{2}$
$5 * 2 = 10$
$10 + 1 = 11$
$5 \frac{1}{2} = \frac{11}{2}$

Multiply these fractions together:

$\frac{16}{5} * \frac{11}{2} = \frac{176}{10} 
$

Simplify the fraction.

$\frac{176}{10} / \frac{2}{2} = \frac{88}{5}$

$88 / 5 = 17 R3 = 17 \frac{3}{5}$

India can paint 17 and 3/5 walls in 5 and a half days.

Mrs. Smith teaches junior high school. During a class party in fourth

MArishka [77]

Question is Incomplete, Complete question is given below.

Mrs.Smith teaches junior high school. During a class party in fourth period, she used 4/5 liters of soda for 12 students. If she had a class party in fifth period and used the same serving size, how many liters did she use for 30 students?

Answer:

Mrs. Smith used 2 liters of soda for 30 students.

Step-by-step explanation:

Given:

Number of students = 12

Amount of soda used for 12 students = 4/5 liters

We need to find amount of soda used for 30 students.

For 12 students = 4/5 liters of soda used

For 30 students = the amount of soda used

By Using Unitary Method we get

Amount of soda used = $\frac{4\times30}{5\times12}=\frac{120}{60} =2 \ litres$

Hence Mrs. Smith used 2 liters of soda for 30 students.
