Note tha the surface area of the toy box is 390cm².
How is this so?
To find the surface area of the toy box, we need to calculate the areas of all the faces and then sum them up.
The toy box is in the shape of a rectangular prism with dimensions:
Length = 15 cm
Width = 5 cm
Height = 6 cm
The surface area of a rectangular prism can be found using the formula
Surface Area = 2(LW + LH + WH)
Substituting the values we have -
Surface Area = 2(15 * 5 + 15 * 6 + 5 * 6)
= 2(75 + 90 + 30)
= 2(195)
= 390 cm²
Hence, the surface area of the toy box is 390 square centimeters.

Identify the unit rate in each graph. Then, order the graphs by unit rate, from least to greatest.
The required rates are: Unit rate of graph K = 3, Unit rate of graph P = 0.5, and Unit rate of graph F = 1. The order from lower to greater is Graph P, graph F, graph K
How did we determine their unit rates?Step 1: As we know that Unit Rate
Step 2: Notice that the in graph K line passes through the point (1,3)
Step 3: (1,3)
It means the value of function is 3 when x= 1
Step 4: So the unit rate of graph K is, 3/1
Step 5: Simplify the expression.
3/1 = 3
Step 6: Similarly we can see that the graph P have the point (2, 1)
Step 7: So the unit rate of graph P will be 1/2
Step 8: Simplify the expression.
1/2 = 0.5
Step 9: The graph F have point (1, 1) so it have unit rate of 1/1
Step 10: Simplify the expression.
1/1 = 1
Step 11: So we have unit rate of graph K = 3, F= 1 and graph P = 0.5
Step 12: Putting them in least to greater order as,
0.5, 1, 3
It follows that;
graph P, graph F, graph K
Therefore, the required answer is,
Unit rate of graph K = 3
Unit rate of graph P = 0.5
Unit rate of graph F = 1

5000 nails in five boxes. the first and second boxes have 2700 nails all together. the second and the third boxes have 2000 nails all together. the third and fourth boxes have 1800 nails all together. the fourth and the fifth boxes have 1700 nails all together. how many nails are in each box
The number of nails in each box is: 1300, 1400, 600, 1200, and 500
Given 5000 nails in five boxes.
Let X denote the universal set.
Then n(X) = 5000.
Let A denote the first box,
B denote the second box,
C denote the third box,
D denote the fourth box, and
E denotes the fifth box.
The first and second boxes have 2700 nails altogether.
⇒n(A ∪ B) = 2700
The second and third boxes have 2000 nails altogether.
⇒n(B ∪ C) = 2000
The third and fourth boxes have 1800 nails altogether.
⇒n(C ∪ D) = 1800
The fourth and fifth boxes have 1700 nails altogether.
⇒n(D ∪ E) = 1700
We need to find out how many nails are there in each box.
That is to find out: n(A), n(B), n(C), n(D), and n(E).
Note that all these five sets are disjoint. This means that the intersection is empty.
n(A ∪ B ∪ C ∪ D) = n(A ∪ B) + n(C ∪ D) = 2700 + 1800 = 4500
n(E) = n(X) - n(A ∪ B ∪ C ∪ D) = 5000 - 4500 = 500
n(D) = n(D ∪ E) - n(E) = 1700 - 500 = 1200
n(C) = n(C ∪ D) - n(D) = 1800 - 1200 = 600
n(B) = n(B U C) - n(C) = 2000 - 600 = 1400
n(A) = n(A U B) - n(B) = 2700 - 1400 = 1300
Therefore, the number of nails in each box is 1300, 1400, 600, 1200, and 500.

Answer:
x = 7.69
Step-by-step explanation:
We need to solve the given problem. It is as follows :
175+14.25x=200+11x
Here, x is a variable. We can take on one side of an equation and constants to the other side such that,
14.25x-11x = 200-175
3.25x=25
x = 25/3.25
x = 7.69

Write an equation of the line using function notation.
Slope 0; through (−3,−2)
The equation of the line is f(x)=
The equation of the line having slope 0 and passing through (-3,-2) is f(x) = -2.
Any horizontal line has the same y-value for every point on the line. We are given that the line passes through the point (-3,-2). This means that f(-3) = -2, since the y-value of the point (-3,-2) corresponds to the value of the function at x = -3.
This is because no matter what x-value we plug into the function, the output (y-value) will always be -2. Therefore, the equation of the line in function notation is f(x) = -2.

The fraction 1¹/₂ + ⁵/₇ = 2³/₁₄
What are fractions?Fractions are numbers written in the form a/b where a and b are integers and b ≠ 0.
How to find what 1¹/₂ + ⁵/₇?Since we have the fractions 1¹/₂ and ⁵/₇ and we want to compute the sum
1¹/₂ + ⁵/₇, we re-write the first fraction as an improper fraction.
So, 1¹/₂ = ³/₂
Now, re-writting the equation, we have
³/₂ + ⁵/₇
To find the sum, wetake the L.C.M of both numbers which 2 × 7 = 14.
So, we make both denominators equal to the L.C.M.
So,
³/₂ × ⁷/₇ + ⁵/₇ × ²/₂ = ²¹/₁₄ + ¹⁰/₁₄
= (21 + 10)/14
= 31/14
= (28 + 3)/14
= 28/14 + 3/14
= 2 + 3/14
= 2³/₁₄
