Answer:
See Below:
Step-by-step explanation:
40,000*8/25= the diameter, because the diameter is 8/25 of the equator which is 40000
Diameter= 40,000*8/25
Diameter= 12,800 km
Answer:
12,800 km
Step-by-step explanation:
Since the length of the Earth's equator is 40,000 km and the diameter is 8/25 the length of the equator, indicates that you would multiply 40,000 by 8/25, which gives you a product of 12,800, or, the diameter of the Earth which is 12,800 km.

Answer:
What is the change for each consecutive input?
✔ 1
What is the change for each consecutive output?
✔ 0.35
What is the rate of change for the relationship?
✔ 0.35
Step-by-step explanation:
The change for each input is 1 beacause the inputs are 10,11,12,13
The change for each consecutive output is 0.35 beacuse we need to subtract 4.1 from 3.75
The rate of change for the relationship is also 0.35

Riko wants to find the distance between the points (−2, −3) and (2, −5). His work is shown. The distance is 8 units. Riko correct? Explain why or why not.
Answer:
incorrect
Step-by-step explanation:
The calculation he has done only calculates the distance between the y- coordinates of the points.
Calculate the distance d using the distance formula.
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (2, - 5)
d = [tex]\sqrt{(2+2)^2+(-5+3)^2}[/tex]
= [tex]\sqrt{4^2+(-2)^2}[/tex]
= [tex]\sqrt{16+4}[/tex]
= [tex]\sqrt{20}[/tex] = [tex]\sqrt{4(5)}[/tex] = 2[tex]\sqrt{5}[/tex] ← exact distance
Answer:Sample Response: No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.

Colton is painting a set of figurines a solid color. It takes him 15 minutes and 5 milliliters of paint to finish a small figurine. It takes him 30 minutes and 8 milliliters of paint to complete a large figurine. Colton plans to paint for at least 360 minutes, and he can use a maximum of 100 milliliters of paint.

Starlight Tree Farm sells Douglas firs and Noble firs. One December they sold 139 more Douglas firs than Noble firs. The total number of trees sold was 377. Which equation could be used to solve for n, the number of Noble fir trees sold?
2n – 139 = 377
n – 139 = 377
n + 139 = 377
2n + 139 = 377
Answer: 2n + 139 = 377

Lydia writes the equation below with a missing value.
y=5x-[]
She puts a value in the box and says that the equation represent a direct variation. Which explains whether the equation could represent a direct variation?
A.The equation has a minus sign, so it cannot represent a direct variation.
B.If she puts 5 in the box, she would have a direct variation.
C.If she puts 0 in the box, she would have a direct variation.
D.The equation is not of the form y = kx, so it cannot represent a direct variation.
Answer:
If she puts 0 in the box she would have a direct variation.
Step-by-step explanation:
Given : Lydia writes the equation y = 5x - __ with a missing value.
She puts a value in the box and says that the equation represents a direct variation.We have to choose the correct option from the given options that explain that the equation could represent a direct variation.When two variables are such that one is a constant multiple of other, we said they are in Direct variation.
That is in form of y = ax , here y and x are in direct variation.Consider the given equation y = 5x - __
For the equation to be in direct variation the value of missing term has to be 0.
then equation becomes,y = 5x
Thus, If she puts 0 in the box she would have a direct variation.

The grassy area of a playground has a side length of x and a side of width of x + 3 what is the area of the playground?
A. A(x)=x^2+3x
B. A(x)=x^2+x+3
C. A(x)=2x+3
D. A(x)=x^2+3
Answer:
A
Step-by-step explanation:
We assume this playground is a rectangle. The area of a rectangle is of the form: A = lw, where l is the length and w is the width.
Here, the length is l = x and the width is w = x + 3. So, plug these in:
A = lw
A = x(x + 3)
Expand this out:
A = x² + 3x
The answer is thus A.
Answer:
A
Step-by-step explanation:
Area = length × width
Area = x × (x + 3)
A(x) = x²+ 3x

How you would solve the following problem: 4.5 + h = 7.3.
Find the sum of the geometric series
1+ 0.8 + 0.8^2 + 0.8^3 + ... + 0.8^19
Work Shown:
a = first term = 1
r = 0.8 = common ratio
We know the common ratio is 0.8 because we multiply this common ratio by each term to get the next term. The easiest to spot this is going from term1 to term2. Put another way, term2/term1 = 0.8/1 = 0.8 is our common ratio.
The general form of the nth term of a geometric sequence is [tex]a(r)^{n-1}[/tex] and because the last term has an exponent of 19, this means n-1 = 19 solves to n = 20. Therefore, we are summing exactly n = 20 terms here.
Use the formula below to take a shortcut rather than painstakingly find all 20 terms and then summing them.
[tex]S = \frac{a*(1-r^n)}{1-r}\\\\S = \frac{1*(1-0.8^20)}{1-0.8}\\\\S \approx \frac{1*(1-0.01152921504607)}{1-0.8}\\\\S \approx \frac{1*(0.98847078495393)}{0.2}\\\\S \approx \frac{0.98847078495393}{0.2}\\\\S \approx 4.94235392476964\\\\[/tex]
This value is approximate.
------------
To check your answer, you could type the following into your calculator
1+0.8+0.8^2+0.8^3+0.8^4+0.8^5+0.8^6+0.8^7+0.8^8+0.8^9+0.8^10+0.8^11+0.8^12+0.8^13+0.8^14+0.8^15+0.8^16+0.8^17+0.8^18+0.8^19
Though as you can see, this is very tedious to type in. This is why the formula in the previous section above is preferred.
What additional information is needed to prove that the triangles are congruent using the AAS congruence theorem? LO ≅ LM OA ≅ MA AngleLOA ≅ AngleLMA AngleLAO ≅ AngleLAM
Answer:
∠LOA≅∠LMA
Step-by-step explanation:
The first two options are incorrect because you need one more set of congruent ANGLES, not SIDES. The last option would prove congruency, but through ASA, not AAS. So it would be the third option.
For both triangles to be congruent by the AAS congruence theorem, the additional information needed is: C. ∠LOA ≅ ∠LMA.
What is the AAS Congruence Theorem?The AAS congruence theorem states that two triangles are proven to be congruent when they have two pairs of corresponding congruent angles and a pair of non-included sides that are congruent.
From the diagram given, we already known that:
LA ≅ LA [congruent side]
∠OLA ≅ ∠MLA [one pair of congruent angles]
Therefore, an additional information that would make both triangles congruent by the AAS congruence theorem is: C. ∠LOA ≅ ∠LMA.

Answer:
123
Step-by-step explanation:
to find the current value of one share just do this
23/100*100=23 so just add 23 on 100 and you will get 123 which is the current value of one share.
