Answer:
There are ten possible digits (0 to 9).
If they can be repeated, you're looking at 10 * 10 *10 * 10 * 10, or 105
This means 100000 possible zip codes if repeatable.
If not, you're looking at one less each time:
10 * 9 * 8 * 7 * 6
90 * 56 * 6
540 * 56 = 30240 zip codes without any repetitions.
Calculate the perimeter of the following shape.
6cm
y=
10 cm
12 cm
5 cm
Answer:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides.
10 cm + 12 cm + 5 cm + 6 cm
= 33 cm
Sally and Suzie both agree that m∠A + m∠B = 180⁰.
Sally claims ∠A and ∠B are supplementary.
Suzie claims ∠A and ∠B are not supplementary because they are not adjacent.
Who is correct?
Answer:
Sally is correct in claiming that [tex]\angle A[/tex] and [tex]\angle B[/tex] are supplementary.
Step-by-step explanation:
Supplementary angles are angles that add up to [tex]180^{\circ}[/tex]. Whether they are adjacent or not is irrelevant to whether they are supplementary. Since [tex]70+110=180[/tex], angles [tex]\angle A[/tex] and [tex]\angle B[/tex] are supplementary.
Solvex2
- 4x=21
using the zero product property.
Answer:
The answer is (x + 3) (x - 7) = 0
Step-by-step explanation:
x² - 4x = 21
x² - 4x - 21 = 0
x² - 7x + 3x - 21 = 0
x(x - 7) + 3(x - 7) = 0
(x + 3) (x - 7) = 0
Thus, The answer is (x + 3) (x - 7) = 0

Gabriela is solving the following equation. Her steps are shown:
Gabriella is not sure she has solved the problem correctly. How can you convince Gabriella if she has solved the problem correctly / incorrectly? If she has solved the problem incorrectly, solve it and convince her of the solution
Answer:
Solution given:
5(9x-8)=4(x+2)
45x-40=4x+8
45x-4x=40+8
41x=48
x=[tex] \frac{48}{41} [/tex]
Gabriella is not correct:
she has done in distribution
5(9x-8)=4(x+2)
45x-40=4x+8 not 45x-8=4x+2.
No, Gabriela is not solving correctly because her second step is wrong.
What is a fraction?In a fraction the upper part is known as numerator and the lower part is known as denominator.
How to solve the problem?The problem is as under
(9x-8)/4=(x+2)/5
The above problem is solved as
5(9x-8)=4(x+2)
45x-40=4x+2
41x=42
x=42/41
Hence the value of x is 42/41 therefore the solution of Gabriella is wrong.

what is the common difference in the sequence (-3, 2, 7, 12, ...)
Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .

Five less then 3 times a number is 3 let x be unknown
number
Answer:
3x-5=3
Step-by-step explanation:
Answer:
2.6 repeating Or 8/3(same thing in fraction form)
Step-by-step explanation:
So, lets iscolate the different parts of this euqation:
Five less than 3 times a number is 3
Or:
5 less than 3 * x = 3
This is a bit tricky here, but it should be:
(3*x)-5=3
Since order of operations, multipcation comes first.
And remember this is 5 less than the 3*x, so its subtracting 5 from 3*x.
This is all equal to 3.
Now lets solve:
(3*x)-5=3
Solve whats in the parthese first:
3x-5=3
Then get 3x alone:
3x=8
Then get x alone:
x=8/3
Or
2.66 repeating
This is your answer(8/3 or 2.6)
Hope this helps!

Answer:
The answer is 7
Step-by-step explanation:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
for our purposes we must rearrange this problem to find one of the sides, not the hypotenuse
[tex] {a}^{2} = {c}^{2} - {b}^{2} [/tex]
plugging in our numbers we get
[tex] {25}^{2} - {24}^{2} = 49[/tex]
[tex] \sqrt{49} = 7[/tex]
