Answer:
17 minutes
Step-by-step explanation:
To answer this question, all we have to do is subtract the original amount of money on the phone card by what is remaining after Keiko's call:
20 - 17.28 = 2.72
Now, we divide this number by 0.16:
2.72 / 0.16 = 17
So, Keiko's call lasted 17 minutes
Hope this helps :)
Which statements are true about the reflectional
symmetry of a regular heptagon? Select two options.
It has only 1 line of reflectional symmetry.
A line of symmetry will connect 2 vertices.
O A line of symmetry will connect a vertex and a
midpoint of an opposite side.
It has 7-fold symmetry.
A line of symmetry will connect the midpoints of 2
opposite sides. lol
A line of symmetry will connect a vertex and a midpoint on an opposite side of a regular heptagon has 7-fold symmetry.
What is symmetry?" Symmetry is defined as the line which divides the geometrical shape into two equal proportion."
According to the question,
Regular heptagon is a polygon with 7equal sides.
Line of symmetry will connect a vertex and a midpoint of an opposite sides.
There are seven such possibilities.
Number of lines of symmetry in regular polygon is same number of sides of polygon.
Hence, regular heptagon has 7-fold symmetry.

#9 Alana made $45
babysitting for 6
hours. How much do
she make per hour?
Step 1:
Start by setting it up with the divisor 6 on the left side and the dividend 45 on the right side like this:
6 ⟌ 4 5
Step 2:
The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
6 ⟌ 4 5
Step 3:
Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.
0
6 ⟌ 4 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
6 ⟌ 4 5
- 0
4
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
6 ⟌ 4 5
- 0
4 5
Step 6:
The divisor (6) goes into the bottom number (45), 7 time(s). Therefore, put 7 on top:
0 7
6 ⟌ 4 5
- 0
4 5
Step 7:
Multiply the divisor by the result in the previous step (6 x 7 = 42) and write that answer at the bottom:
0 7
6 ⟌ 4 5
- 0
4 5
4 2
Step 8:
Subtract the result in the previous step from the number written above it. (45 - 42 = 3) and write the answer at the bottom.
0 7
6 ⟌ 4 5
- 0
4 5
- 4 2
3
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 45 divided by 6 calculated using Long Division is:
7
3 Remainder

Solve for z.
4/z
12/5
Answer:
[tex]\frac{5}{3}[/tex]
Step-by-step explanation:
[tex]\frac{4}{z} = \frac{12}{5}[/tex]
4 (5) = z (12)
20 = z (12)
20 = 12z
z = [tex]\frac{5}{3}[/tex]
Write an equation that is parallel to y=4/5x+1?
Answer:
y=4/5×
Step-by-step explanation:
its parallel. U just have to leave the slope alone but find a different y intercept.
When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is
[tex]y=\frac{4}{5}(x)[/tex]
Given :
Given the equation is [tex]y=\frac{4}{5}x+1[/tex]
the given equation is in the form of y=mx +b
where m is the slope and b is the y intercept
[tex]y=\frac{4}{5}x+1\\slope =\frac{4}{5}[/tex]
when two lines are parallel to each other then the slopes are equal
slope of parallel line = slope of given line
slope of parallel line =[tex]\frac{4}{5}[/tex]
When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is
[tex]y-0=\frac{4}{5}(x-0)\\\y=\frac{4}{5}(x)[/tex]

Tonya wrote the equation below which solves for x.
x = 150 minus 6 y
Which equation is equivalent to Tonya’s equation?
x + 150 = 6 y
x + 6y = 150
2x + 3y = 75
2 x minus 3 y = 75
Given parameters:
x = 150 minus 6 y
Interpreting this gives;
minus = subtraction = -
x = 150 - 6y
Now bring the variables together;
x + 6y = 150
The option that matches with this equivalent.
The other choices are wrong;
a, x + 150 = 6 y
x - 6y = 150 wrong
c. 2x + 3y = 75 mulitply through by 2;
2(2x + 3y) = 2(75)
4x + 6y = 150 wrong
d. 2x - 3y = 75
Multiply by 2;
2(2x -3y) = 2(75)
4x - 6y = 150
Answer:
x+6y = 150 (B)

Answer:
Options A, D and F
Step-by-step explanation:
From the picture attached,
lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.
From the angles formed at the points of intersection,
∠5 ≅ ∠8 [Vertical angles]
∠5 ≅ ∠4 [Alternate interior angles]
∠5 ≅ ∠1 [Corresponding angles]
Therefore, Options A, D and F will be the correct options.
