What ten times 13 divided by 130, how you solve it
Answers
You can find this by adding 10, 13 times
Looking like this: 10+10+10+10+10+10+10+10+10+10+10+10+10= 130
Or, another simpler way would be to multiply 1 x 13 = 13 and then add the number of 0's that are in the equation, which there is only one, so we then get 130!

Which monomials are perfect squares? Check all that apply. 6x2 9x8 16x9 25x12 36x16
Answers
9x^8 = (3x^4)^2
25x^12 = (5x^6)^2
36x^16 = (6x^8)^2
answer
9x^8
25x^12
36x^16
Answer: Options Third, Second , Fourth are correct.
Step-by-step explanation:
Since we have given that
[tex]6x^2\\\\9x^8\\\\16x^9\\\\25x^{12}\\\\36x^{16}[/tex]
Since we know that
9, 16, 25, 36 are perfect squares.

andy constructed a triangle angle 1 and 2 are the same but angle 3 has a measurement of 100 degrees what is the measurement of angle 1 and 2
Answers
We know that the angles of a triangle always add up to 180. To find the measurement of angle 1 and 2, let's solve for this equation.
2x + 100 = 180, where x=angle 1 = angle 2. Subtract 100 from both sides
2x = 80 Divide both sides by 2
x = 40
What sum or difference is equivalent to the following expression 5-3x/5 A 1+3/5 B 1+3x/5 C 1-3x/5 D 25-15x

Answer:
Option C is the answer.
Step-by-step explanation:
The given expression is [tex]\frac{(5-3x)}{5}[/tex]
We solve it further to get the simplified form.
[tex]\frac{(5-3x)}{5}[/tex] = [tex]\frac{5}{5}-\frac{3x}{5}[/tex]
= [tex](1-\frac{3x}{5})[/tex] [Since [tex]\frac{a-b}{a}=\frac{a}{a}-\frac{b}{a}][/tex]
Therefore, option C matches the simplified form of the expression.
Parallel slope of 8x+y=11
Answers
First, we must put this into slope-intercept form, just so that we see this better :)
Slope-intercept form : y=mx+b where m=slope, b=y-intercept.
Subtract 8x from both sides.
y = -8x + 11
-8 is in the "m" spot. Remember, m=slope :)
So, our slope is -8.
Remember, if 2 lines are parallel to one another, then they have the same slope.
So, the parallel slope of -8 is -8.
However, if 2 lines are perpendicular from one another, they have negative reciprocal slopes :)
~Hope I helped!~
Answer:
The slope parallel to this line is -8.
Step-by-step explanation:
That's because parallel lines have the same slope. Therefore to find the slope of a parallel line, we must first find the slope of this one. On order to do that, we need to solve for y and then look at the coefficient of x.
8x + y = 11
y = -8x + 11
Therefore, we know the slope to be -8, which means the parallel slope must also be -8.

In which of these cases is each stamp worth the most?
1. 7 of the same stamp worth a total of $3.15
2. 8 of the same stamp worth a total of $3.20
3. 10 of the same stamp worth a total of $4.10
4. 16 of the same stamp worth a total of $4.80
Answers
3.15 /7 = 0.45
3.20/8 = 0.40
4.10/10 = 0.41
4.80/16 = 0.3
Answer is 1. 7 stamps worth 3.15
Answer:
1. 7 stamps for $3.15 → $0.45/stamp
Step-by-step explanation:
Calculate the price per stamp for each scenario:
1)[tex]\frac{3.15}{7}=0.45[/tex]/stamp
2)[tex]\frac{3.20}{8}=0.40[/tex]/stamp
3)[tex]\frac{4.10}{10}=0.41[/tex]/stamp
4)[tex]\frac{4.80}{16}=0.3[/tex]/stamp
Therefore the first scenario of stamps will be the worth the most per stamp, as it has a higher cost than the rest.

Check out the attached image "figure 1". The graph of the line is shown in red. The red line is the equation y = -3x+4. The answer choices A through D are shown as blue points. Only point A = (1,7) is not on the red line. So point A is not a solution to the equation.
Answer: Choice A) (1,7)
=============================================
Problem 2)
First error is in step 3, specifically the "additive inverse" portion. It should be "additive property of equality" since we're adding 10x to both sides.
The second error is the reasoning in step 5. Instead of "symmetric property" it should be "subtraction property of equality".
The third error is all of line 7. We are not multiplying both sides by 6. Instead we divide both sides by 6. The reasoning should be "division property of equality"
Finally, the last error is the first column on line 8. The final answer should be x = 7 (since 42 divided by 6 = 7)
See the image attachment "figure 2" for the visual summary of the table, and what needs to be fixed.

Parabola is a plane curve with a U shape.
The parabola equation is given as:
y = a (x – h)² + k
The equation of a parabola that has a vertex (-3, 7) and passes through the point (-2, 11) is y = 11.
What is a parabola?Parabola is a plane curve with a U shape.
The parabola equation is given as:
y = a (x – h)² + k
(h, k) is the vertex.
We have,
Parabola:
Vertex = (-3, 7)
Passes through the point = (-2, 11)
The equation of the parabola is y = a (x - h)² + k
(-3, 7) = (h, k)
Since the parabola passes through the point (-2, 11) we get,
11 = a (-2 - (-3))² + 11
11 = a (-2 + 3)² + 11
11 = a x 1 + 11
11 = a + 11
Subtract 11 on both sides.
0 = a
a = 0
Now,
y = 0 (x + 3)² + 11
y = 0 + 11
y = 11
Thus,
The equation of a parabola that has a vertex (-3, 7) and passes through the point (-2, 11) is y = 11.
