Can an octagon have interior angles that measure 100 degrees, 156 degrees, 125 degrees, 90 degrees, 175 degrees, 160 degrees, and 140 degrees? Explain.
9514 1404 393
Answer:
yes
Step-by-step explanation:
The 7 angles listed have a total of 946 degrees. The total interior angle measure in an octagon is 1080 degrees. So, the remaining angle must have a measure of 134°. The figure is entirely feasible.
Answer:
yes because the 7 angles listed have a total of 946 degrees. The total interior angle measure in an octagon is 1080 degrees. So, the remaining angle must have a measure of 134°. The figure is entirely feasible.

What number cannot be divided into 9 groups without a remainder?
Answer:
The answer is B) 432
Step-by-step explanation:
The 4 in 432 becomes a 3, because we can't subtract 6 from 3. The 3 becomes 13 and if we subtract 13 with 6... We get 7.
I got 0 with option B... With A I got 2 which is a remainder. With C I got 6.5 (repeating). And with D I got 7.77777777778.
Hence, B) 432 is the correct option.
Check screenshot of my work below.
(I forgot to include 48 on top of the division I just did. Don't mind that too much..)
A) 326
[tex] \frac{326}{9} [/tex]
[tex] = 36.2222222222 [/tex]
B) 432
[tex] \frac{432}{9} [/tex]
[tex] = 48[/tex]
C) 531
[tex] \frac{531}{9} [/tex]
[tex] = 59[/tex]
D) 630
[tex] \frac{630}{9} [/tex]
[tex] = 70[/tex]
so, the correct answer is option A.
Is the following number rational or irrational?
0.4
——
0.8
Choose 1 answer:
Rational
or
Irrational
0.4/0.8
= 4/10 × 10/8
= 4/8
= 1/2
= 0.5
0.5 is a RATIONAL number (A).
=》0.5 is a rational number because it's in the form of p/q (5/10) where both p & q are integers & q is not equal to 0.
=》 Also, q can be expressed in the form of 2ⁿ × 5ᵐ (q = 10 = 2¹ × 5¹) which makes it a rational number.

Step-by-step explanation:
A model rocket is launched from the top of a building. The height (in meters) of the rocket above the grown is given by h(t)=-6t^2+30t+10 , where t is the time (in seconds) since the rocket was launched. What is the rocket’s maximum height?
Answer:
47.5 Meters
Step-by-step explanation:
Find where the derivative changes from positive to negative (local maximum)
h(t)=[tex]-6t^2+30t+10[/tex]
h'(t)=[tex]-12t+30[/tex]
Find where the derivative equals zero
Theres no spot where the derivative wont exist because its a polynomial.
-12t=-30
t=[tex]\frac{5}{2}[/tex]
Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.
Now plug into original equation
h(2.5)=[tex]-6(2.5)^2+30(2.5)+10[/tex]
=-37.5+75+10
=47.5

"five more than the product of four and a number is
equal to the product of three and that same number
increased by six."
A. X=-1
B. X= 1
C. X= 3
D. X= 1/2
Answer:
B
Step-by-step explanation:
Let the number = x
Product: 4 * x
Add 5: 4x + 5
=
3x + 6
Now equate the two parts.
4x + 5 = 3x + 6 Subtract 5 from both sides
4x + 5 - 5 = 3x + 6 - 5 Combine
4x = 3x + 1 Subtract 3x from both sides
4x-3x=3x -3x + 1 Combine
x = 1

Step-by-step explanation:
Let the number be " x ".
1 / 5 of x is 105
x / 5 = 105
x = 105 x 5
x = 525
Therefore,
the number is 525.
Answer:
525Step-by-step explanation:
1/5 of a number is 105, and the number is
105 * 5 = 525

Find the slope of each line please help
Answer: The slope should be 2/3
Step-by-step explanation: Slope is rise over run. Remember you always rise before you run. So in this case you start at the origin and go up until you get to the point on the line where the line is centered. You go up 3 times and thats where the first actual point is. Then move to the side until you get to the line which is 2 to the right. so therefore your answer is 3/2
what is the initial value of the graph?
Answer:
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y- value of the point at which the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope. Which statement best describes a geometric sequence?

Seven times the sum of a number and 1 is 28.
What is the number?
Enter your answer in the box.
The number is
The number in the question that gives 28 after the operations is; 3
We are told that the product of seven and the sum of a number and 1 is 28.
Let the number be x. Thus;
7(x + 1) = 28
Use division property of equality to divide both sides by 7.
7(x + 1)/7 = 28/7
(x + 1) = 4
Use subtraction property of equality to subtract 1 from both sides to get;
x + 1 - 1 = 4 - 1
x = 3
Therefore, in conclusion the number is 3.

What is 6 1/2 + 9 3/8
Answer: 15 7/8
Step-by-step explanation:
Add the whole numbers first 6+9 to getting 15
Now find the lowest common denominator for both the fractions. In this case it is 8.
3/8 would stay the same however 1/2 would become 4/8. 4/8 + 3/8 is 7/8.
15 add 7/8 is 15 7/8
