Answer:
A shape has reflection symmetry if there exists a line of reflection that carries the shape onto itself. This line of reflection is called a line of symmetry. In other words, if you can reflect a shape across a line and the shape looks like it never moved, it has reflection symmetry.

what is -60 ÷_______ = 12
Answer:
5 is the answer.
60÷5=12 as 12×5=60
Answer:
-5
Step-by-step explanation:
The equation, -60 ÷ ____ = 12 can be easily reversed to help us find the missing divisor.
To find the missing divisor, we can rewrite the equation as -60 ÷ 12 = ___.
This way, we can find what the quotient (the divisor of the original equation).
-60 ÷ 12 is equal to -5, so therefore the divisor of -60 ÷ ___ = 12 is -5!
So the finished equation would look like this: -60 ÷ -5 = 12!
(To check your work, multiply -5 by 12 to see if it equals -60 :D)
Hope this helps!!
what values make t true is my inequality is (5-2t)<-4
Answer:
t ≥ 5
Step-by-step explanation:
I) Find what t needs to be at least, represent this with u:
5 - 2u = -4
-2u + 5 = -4 (Simplify by swapping signs and terms for 5 - 2u)
-2u = -9 (Subtract 5 from both sides)
2u = 9 (Make both sides positive values)
u = 4.5 (Divide both sides by 2)
II) Make an inequality for t:
Since t needs to be equal to or greater than 4.5, our inequality will be:
t ≥ 4.5

Answer:
96 minutes
Step-by-step explanation:
Time taken by 6 pipes to fill a tank = 80 minutes
Time taken by 1 pipe to fill a tank = 80×6 = 480 minutes
Tim taken by 5 pipes to fill a tank = 480/5 = 96 minutes
Answer:
66 min and 7 seconds
Step-by-step explanation: 80 divided by 6 and then multiply the answer by 5

Answer/Step-by-step explanation:
✔️Find BC:
Reference angle = 50°
Opposite = BC
Adjacent = 5 cm
Based on trigonometric ratio, thus:
Tan 50 = BC/5
Multiply both sides by 5
BC = 5 × tan 50
BC = 5.96 cm (to 3 s.f)
✔️Find x:
Reference angle = 38°
Opp = x
Adj = BC = 5.96 cm
Based in trigonometric ratio, thus:
Tan 38 = x/5.96
Multiply both sides by 5.96
x = 5.96 × tan 38
X = 4.66 (3 s.f)

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below
Answer:
2, 3, 4
Step-by-step explanation:
Renee bought 7 potatoes at the supermarket. The shortest diameter of each,
in centimeters, is shown below.
2, 3, 4, 4, 6, 6, 7
After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Reneetsed?
Solution:
The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.
The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.
Given that the diameter of the potato as:
2, 3, 4, 4, 6, 6, 7
Given that after removing one potato, the median of the remaining potatoes was 5 centimeters.
After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.
To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.
If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5

So, the expression becomes:
[tex]z*1+z*1+z*1+z*1=[/tex]
Step 2: Distributive Property
This states that:

So, the expression becomes
[tex]z*1+z*1+z*1+z*1=[/tex]
[tex]z(1+1+1+1)=[/tex]
Step 3: Addition
Here, we simply add the expressions in the bracket
[tex]z(1+1+1+1)=[/tex]
[tex]z(4) =[/tex]
[tex]z*4=[/tex]
Step 4: Commutative Property of Multiplication
This states that:
[tex]ab=ba[/tex]
So, we have:
[tex]z*4=[/tex]
[tex]z*4 = 4*z[/tex]
[tex]z*4 = 4z[/tex]
-7(v + 5) = 35 help
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
v = − 10
Step-by-step explanation:
you have to tell us what to do to help otherwise we are just guessing and also thats not a lot of points
The solution to the equation is v = -10.
To solve the equation -7(v + 5) = 35, follow these steps:
Step 1: Distribute the -7 on the left side of the equation:
-7v - 7(5) = 35
Step 2: Simplify the equation:
-7v - 35 = 35
Step 3: Move the constant term (-35) to the right side of the equation by adding 35 to both sides:
-7v = 35 + 35
-7v = 70
Step 4: Finally, solve for v by dividing both sides by -7:
v = 70 / -7
v = -10
So, the solution to the equation is v = -10.
