Answer:
(k + 0.04)(k - 0.04)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
k² - 0.0016 = k² - (0.04)²
= (k + 0.04)(k - 0.04)
Hint: 0.0016 = [tex]\frac{16}{1000}=\frac{4^{2}}{100^{2}}=(\frac{4}{100})^{2} = (0.04)^{2}[/tex]

Step-by-step explanation:
70 students have a skateboard.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Total students are 125.
And to find the percentage of 56, we have to take the fraction.
56% of 125 students:
56 x 125 /100
= 7000/100
= 70
Therefore, 70 students have a skateboard.

Camille's kitchen has an area of 80 square feet. The kitchen is 8 times as many square feet as Camille's pantry. If the pantry is 2 feet wide, what is the length of the pantry? First find the area of the pantry. Solve on paper and check you answer on Zearn. The area of the pantry is square ft.
Answer:
Length of the pantry = 5 feet
Step-by-step explanation:
Camille's kitchen has an area of 80 square feet. The kitchen is 8 times as many square feet as Camille's pantry.
Step 1
Area of Camille's kitchen = 8(Area of Camille's pantry)
Area of Camilla kitchen = 80 square feet
80 square feet = 8(Area of Camille's pantry)
Area of Camille's pantry = 80 square feet/8
Therefore:
Area of Camille's pantry = 10 square feet
Step 2
If the pantry is 2 feet wide, what is the length of the pantry?
The shape of the pantry is rectangular hence:
The area of the pantry = Length × Width
Area of the pantry = 10 square feet
Width = 2 feet
Length = Area of the pantry/Width
Length = 10 square feet/2 feet
Length = 5 feet

Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

Answer:
Step-by-step explanation:
Use Pythagorean theorem.
Hypotenuse² = base² + altitude²
5) x² = 12² + 6²
= 144 + 36
x² = 180
x = √180
x = 13.42 ft
6) 25² = x² + 19²
625 = x² + 361
625 - 361 = x²
x² = 264
x = √264
x = 16.25 m
7) x² = 7² + 576
= 49 + 576
= 625
x = √625
x = 25 in
8) 2.5² = 2²+ x²
6.25 = 4 + x²
6.25 - 4 = x²
x² = 2.25
x = √2.25

What is the volume of the triangular prism
Hight 10in
Base 14 in
Length 6
Answer:
[tex]V=336\ in^3[/tex]
Step-by-step explanation:
Triangular Prism
Given a triangular prism of base area A and height H, its volume is obtained with the formula:
V = AH
The area of the base is calculated as follows:
[tex]A = \frac{WL}{2}[/tex]
Where W is the width and L is the length. Both dimensions must be perpendicular.
The triangle of the base has a hypotenuse equal to 10 in and the width is 6 in, the length is calculated by:
[tex]L=\sqrt{10^2-6^2}[/tex]
[tex]L=\sqrt{100-36}=\sqrt{64}[/tex]
L = 8 in
The area is:
[tex]A = \frac{6*8}{2}[/tex]
[tex]A = 24\ in^2[/tex]
Finally, the volume is:
[tex]V = 24\ in^2*14\ in[/tex]
[tex]\boxed{V=336\ in^3}[/tex]

Which of the following best describes the graph above?
A.
neither a relation nor a function
B.
function only
C.
relation only
D.
both a relation and a function
Answer:
Option C
Step-by-step explanation:
To test a graph whether it represents a function or relation we conduct a vertical line graph.
If the vertical line intersect the graph at two different points, graph represents a relation only.
By analyzing the given graph with the vertical line test,
Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),
Given graph represents a relation only.
Option C is the answer.

Dan,Gordon and malachy share some sweets in the ratio 2:2:5. Dan gets 24 sweets.How many did malachy get?
Answer:
60 sweets
Step-by-step explanation:
The total ratio = 2 + 2 +5 = 9
Let x = total sweets shared
Dan got 2/9 of x. This is equal to 24
the equation for this is - [tex]\frac{2}{9}[/tex] × x = 24
to solve for x, divide both sides by [tex]\frac{9}{2}[/tex]
x = 108 = total sweet shared
sweets malachy got = [tex]\frac{5}9}[/tex] x 108 = 60 sweets
