Answer:
a) k = 2/5
b) y = 2/5x
c) y = 2 3/5
Step-by-step explanation:
a)The proportional relation is described by the equation ...
y = kx . . . . . . k is the constant of proportionality
The value of k can be found by dividing the equation by x:
y/x = k = (2 1/4)/(5 5/8) = (9/4)/(45/8) = 18/45
k = 2/5
__
b)As above, the equation is ...
y = kx
y = 2/5x
__
c)Using 6.5 for x, we have ...
y = (2/5)(6.5) = 2.6 = 2 3/5

Step-by-step explanation:
∛100 = ?
100 = 2 x 2 x 5 x 5
∛100
= ∛ ( 2 x 2 x 5 x 5 )
= 4.642
4.642 ~ 4.5
The approximation 4.642 can also be written as 4.5
Therefore,
∛100 = 4.5
According to the U.S. Census Bureau, the total number of households in the state of Indiana is 2,478,846. The number of households with at least one resident who is 65 years of age or younger is 1,885,128. What percentage of Indiana households have at least one resident who is 65 years of age or younger? (Round to the nearest hundredth percent)
Step-by-step explanation:
100% = 2,478,846
1% = 100%/100 = 2,478,846/100 = 24,788.46
how many % are 1,885,128 ?
we need to see how often 1% fits into that amount.
1,885,128 / 24,788.46 = 76.04861294... %
so, the rounded answer is
76.05%
The required percentage of Indiana households that have at least one resident who is 65 years of age or younger is 76.05.
Given that,
According to the U.S. Census Bureau, the total number of households in the state of Indiana is 2,478,846. The number of households with at composition least one resident who is 65 years of age or younger is 1,885,128.
The percentage is the ratio of the composition of matter to the overall of matter multiplied by 100.
Here,
Total population = 2,478,846
The total population of at least one resident who is 65 years of age or younger is 1,885,128.
Required percentage = 1,885,128 / 2,478,846 × 100%
Required percentage = 76.05%
Thus, the required percentage of Indiana households that have at least one resident who is 65 years of age or younger is 76.05.

What is the value of x? Midsegments of triangles

Mr. Levy has a budget of $18,000. Uniforms for the marching band cost $315 each, and he needs 62 uniforms. He says, "Since 60x$300=$18,000, I can stay within the budget." Do you agree? Explain.
Answer:
No. See explanation below.
Step-by-step explanation:
No.
Since 60 × $300 = $18,000, he would be exactly at budget if he needed 60 uniforms and if each uniform cost $300, but he needs more than 60 uniforms, and each uniform costs more than $315, so the total cost is definitely more than $18,000.
No, Mr. Levy would not be staying within budget.
Sure, 60 · $300 is $18,00, but he didn't take in the other $15 or the 2 extra uniforms.
If he were to do the math correctly, he should have done 62 · $315, which would be $19,530.
If Mr. Levy were to buy all the uniforms and not worry about it because "60 · $300 is $18,000," he would go over the budget by $1,530.

Find the missing term so that r2 + _____ + 100 forms a perfect square trinomial.
A. 10r B. 20r C. −10r D. −20r
Answer:
B 20r
Step-by-step explanation:
r² + + 100
r² = (r ) ( ) signs are all positive. 100 = (10) (10) last number. so
(r + 10)(r + 10)
r(r+ 10) + 10(r + 10)
r² + 10r + 10r + 100
r² + 20r + 100

What is the z-score of x, when x = 1 and X ~ N (12,3)? Must Show Working
Answer:
=1−12/3≈−3.67
Step-by-step explanation:
The z-score of x = 1, when x ~ N(12, 3), is approximately -3.6667.
To find the z-score of x when x = 1, we'll use the formula for z-score:
z = (x - μ) / σ
Given:
x = 1
μ (mean) = 12
σ (standard deviation) = 3
Substituting these values into the formula, we get:
z = (1 - 12) / 3
Calculating the numerator:
1 - 12 = -11
Dividing the numerator by the denominator:
-11 / 3 ≈ -3.6667
Therefore, the z-score of x = 1, when x follows a normal distribution with a mean of 12 and a standard deviation of 3, is approximately -3.6667.

Investing $10,000 in a savings account at 3% annual interest compounded monthly will result in approximately how much money after
10 years?
formula: A = P(1 + r/m)^mt
O $10, 564.68
O $13, 439.16
O $13, 493.54
O $13,000.00
Answer:
$13,493.54
Step-by-step explanation:
We are gonna use the provided formula: A = P(1 + r/m)^mt
A = Final amount (?)
P = Starting amount (10,000)
r = rate (0.03)
m = times applied (12 since it is compounded monthly)
t = years (10)
A = 10,000(1 + 0.03/12)^12·10
I would suggest using a calculator, but let's try to get a little far with this
A = 10,000(1 + 0.0025)^12·10
A = 10,000(1.0025)^120
A = 13,493.535471908333
A cuboid in which the sum of its dimensions is 9 cm., then the sum of its edge lengths - cm. (18 or 27 or 36 or 45)
The number of sides or edges on a cuboid are twelve, and the sum of the
edges is the sum of the twelve edges.
The sum of the edge lengths = 36 cm
Reasons:
The given parameters are;
The sum of the dimension of the cuboid = 9 cm
Required:
The value sum of the dimension of the edges the cuboid.
Solution:
The dimensions of a cuboid are; Length, l, width, w, and height, h
We get;
l + w + h = 9
The number of times that each dimension appear = 4 times
4 edges with the same length as the height, h
4 edges with the same length as the width, w
4 edges with the same length as the length, l
The sum of the edge lengths is therefore; Sum Edges = 4·l + 4·w + 4·h
Which gives;
Sum Edges = 4·l + 4·w + 4·h = 4 × (l + w + h) = 4 × 9 = 36
The sum of the edge lengths = 36 cm.

A ladybug crawls around the outside of a rectangle that measures 7.5 cm by 8.5 cm. The ladybug stays exactly 3.9 cm from the rectangle at all times to form a larger figure. What is the area of the new rectangle bound by the path of the bug?
Answer:
185.64 [tex]cm^{2}[/tex]
Step-by-step explanation:
Width =7.5+3.9*2 = 15.3 cm
Length = 8.5+3.9*2=16.3 cm
Big Area = 15.3*16.3 = 249.39 [tex]cm^{2}[/tex]
Small Area = 7.5*8.5 = 63.75 1 [tex]cm^{2}[/tex]
area bounded by the path of the bug = 249.39-63.75 = 185.64 [tex]cm^{2}[/tex]
If a total of 1100 square centimeters of material is to be used to make a box with a square base and an open top, find the largest possible volume of such a box.
Answer:
Step-by-step explanation:
Let x = base side length
y = side height
volume V = x²y
y = V/x²
surface area
A = x² + 4xy
A = x² + 4x(V/x²)
A = x² + 4V/x
Solving for volume
V = (A - x²)(x/4)
V = ¼(Ax - x³)
a maximum will occur when the derivative equals zero
V' = ¼(A - 3x²)
0 = ¼(A - 3x²)
0 = A - 3x²
3x² = A
3x² = 1100
x² = (1100 / 3)
x = √(1100/3)
V = (A - x²)(x/4)
V = (1100 - √(1100/3))²(√(1100/3)/4)
V = 3,510.56606...
V = 3510.6 cm³
The box height will be half of the base side length.
y = ½√(1100/3)

A bucket holds 4 liters of water. If a ladle can scoop out 1/4 of a liter, how many scoops will it take to empty the bucket?
Answer:
3 scoops will take to empty the bucket because 1 scoop has been taken out of the bucket
Answer:
The answer is 4 scoops.
Step-by-step explanation:
The question states that a ladle can scoop 1/4 of a liter at a time from the bucket, which is taking out a quarter of water from the bucket. Taking 2/4 liters of water from the bucket would be taking half of the water away. Taking another scoop of water out of it would be 3/4, and 4/4 would be taking all of the water out. Therefore, your answer is 4.
