how many lines of symmetry does this rectangle have?
Answer:
sorry I don't know
Step-by-step explanation:
you have no image I can't tell
Answer: 2
Step-by-step explanation:
Rectangles have 2 lines of symmetry. One of them is vertically down the middle, and the other one is horizontally down the middle lengthwise. However, you can not draw the 2 symmetry lines diagonally in a rectangle from each corner to the opposite corner. An image is attached for a reference/example of this.

Which equation is NOT true?
Answer:
B
Step-by-step explanation:
Using the method of cross- multiplication
[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] ⇒ ad = bc
If ad ≠ bc then equation is not true
A
[tex]\frac{10}{12}[/tex] = [tex]\frac{5}{6}[/tex] , then
10 × 6 = 12 × 5 = 60 ← equation is true
B
[tex]\frac{69}{100}[/tex] = [tex]\frac{6}{10}[/tex] , then
69 × 10 = 690 and 100 × 6 = 600
690 ≠ 600 ← equation not true
C
[tex]\frac{10}{5}[/tex] = [tex]\frac{200}{100}[/tex] , then
10 × 100 = 5 × 200 = 1000 ← equation is true
D
[tex]\frac{12}{4}[/tex] = [tex]\frac{6}{2}[/tex] , then
12 × 2 = 4 × 6 = 24 ← equation is true
Hi!
I can help you with joy! :)
• Here, we need to determine if each equation is true by simplifying fractions.
• The 1st equation states that
10/12 = 5/6
Is it true?
Let’s simplify 10/12 to find out.
Divide 10 and 12 by 2:
5/6
Thus. The 1st equation is true.
How about the next one?
We have 3 options left.
69/100=6/10
Is that correct?
Nope!
Why?
If we simplify 69/100, we will not get 6/10.
In fact, 69/100 cannot be simplified.
Thus, the second equation is not true.
Now, how about Options C and D?
Well, both of these equations ARE true.
Thus, the second equation is not true.
Hope it helps.

Which graph represents the solution of |–2 + (x – 3)| < 7?
Answer:
D
Step-by-step explanation:
the "<" (or "smaller") symbol tells us that the solution must have empty dots at the interval ends, as these values are not included in the solution.
otherwise, we would have a "<=" ("smaller or equal") symbol.
let's start for the first limit to calculate without the absolute value :
-2 + (x - 3) < 7
-5 + x < 7
x < 12
the other end we get by multiplying only the left side (still without the absolute value) by -1 and do it again :
-1×(-2 + (x - 3)) < 7
2 - (x - 3) < 7
2 - x + 3 < 7
-x + 5 < 7
-x < 2
x > -2 (remember, when we multiply the whole inequality, left and right side, by a negative value, we need to flip the inequality symbol).

For each inequality, find two For each inequality, find TWO values for that make the inequality true.
X+3>70
A. 61
B. 66
C. 50
D. 67
E. 70
Answer: Choice D and Choice E
Explanation:
Subtract 3 from both sides
x+3 > 70
x+3-3 > 70-3
x+0 > 67
x > 67
Any number larger than 67 will make the original inequality to be true.
Unfortunately, only E) 70 fits the description.
D) 67 won't work since 67 > 67 is false.
However, I have a feeling that the original inequality might be [tex]x+3 \ge 70[/tex]. If so, then 67 would work because [tex]67\ge 67[/tex] is true.
So I'll assume that this is the inequality you meant to type out.
A bicycle has a listed price of $556.98 before tax. If the sales tax rate is 8.75% find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
Total Price with Tax: $ 605.72
Step-by-step explanation:
We can write an equation for the total cost of the bicycle as:
C=p+(t×p)
Where:
C is the total cost we are trying to calculate.
p is the list price - $556.98
t is the tax rate - 8.75%. "%" means "out of 100" or "per 100", Therefore 8.75% can be written as 8.75 [tex]\frac{x}{100}[/tex].
Substituting and solving for C gives:
C = $556.98([tex]\frac{8\\.75}{100}[/tex]×$556.98)
C = $556.98+$48.74
C = $605.72

Nisha is looking out the window of her apartment building at a sculpture in a park across the street. The top of Nisha's window is 80 feet from the ground. The angle of depression from the top of Nisha's window to the bottom of the sculpture is 20°. How far away from the building is the sculpture? Round your answer to the nearest hundredth. 29. 11 feet 75. 18 feet 128. 67 feet 219. 80 feet.
Answer:
(d) 219.80 ft
Step-by-step explanation:
The side opposite the angle is given, and we want to find the side adjacent. The relevant trig relation is ...
Tan = Opposite/Adjacent
tan(20°) = (80 ft)/(distance to sculpture)
This rearranges to ...
distance to sculpture = (80 ft)/tan(20°) ≈ 219.80 ft
if x + y = 12 and x * y = -360 what are the values of x and y
Step-by-step explanation:
x + y = 12
x × y = -360
we need to transform one equation into an identity of one variable being expressed by the other variable.
e.g. the first equation gives us
x = -y + 12
and then we use that in the second equation :
(-y + 12) × y = -360
-y² + 12y = -360
y² - 12y - 360 = 0
the general solution for such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = y
a = 1
b = -12
c = -360
y = (12 ± sqrt(144 - 4×1×-360))/2 =
= (12 ± sqrt(144 + 1440))/2 = (12 ± sqrt(1584))/2 =
= 6 ± sqrt(1584/4) = 6 ± sqrt(396) = 6 ± sqrt(36×11) =
= 6 ± 6×sqrt(11)
y1 = 6 + 6×sqrt(11) = 25.89974874...
y2 = 6 - 6×sqrt(11) = -13.89974874...
x1 = -y1 + 12 = -13.89974874...
x2 = -y2 + 12 = 25.89974874...
so, we see, they are interchangeable.
the solution is either
x = 25.89974874...
and
y = -13.89974874...
or
x = -13.89974874...
and
y = 25.89974874...
What is the length of the base of a right triangle with an area of 15 square meters and a height of 3 meters?
5 m
10 m
30 m
45 m
The area of a right triangle is the amount of space on it
The length of the base is 10 meters
How to determine the length of the baseThe given parameters are:
Area = 15 square meters
Height = 3 meters
The area of the triangle is:
Area = 0.5 * Base * Height
So, we have:
15 = 0.5 * Base * 3
Divide both sides by 0.5
30 = Base * 3
Divide both sides by 3
10 = Base
Rewrite as:
Base = 10
Hence, the length of the base is 10 meters

Chris buys 2 identical bags of cherries to make a pie.
There are more than 10 but less than 30 cherries in each bag.
Chris eats 7 cherries, then uses half of the rest in his pie.
Chris uses 11.5 cherries for his pie.
How many cherries were in each bag to start with?
==================================================
Explanation using mental math:
He uses 11.5 cherries for his pie, which is half the amount left (after eating those 7 cherries).
This means 2*11.5 = 23 cherries were left over after he ate those seven. In other words, half of 23 is 11.5
If we reverse time, then we get those 7 cherries back to get 7+23 = 30 cherries total. Divide those up equally between the two bags and we get 30/2 = 15 cherries per bag.
Going forward in time we have 15 cherries per bag, so 2*15 = 30 total. He eats 7 to be left with 30-7 = 23 cherries. That cuts in half to 23/2 = 11.5 cherries for his pie.
---------------
Explanation using algebra
c = number of cherries in each bag.
10 < c < 30 based on the second sentence
2c = number of cherries total from both bags combined
2c-7 = the amount left after Chris eats those 7 cherries
(2c-7)/2 = he uses half of the remaining cherries for the pie
Set that equal to the 11.5 number stated and solve for c.
(2c-7)/2 = 11.5
2c-7 = 11.5*2
2c-7 = 23
2c = 23+7
2c = 30
c = 30/2
c = 15
We effectively follow similar steps as when we did the mental math route.
Notice how c = 15 makes 10 < c < 30 true.

Answer:
