A ribbon is 5 2 5 yards long. Mae needs to cut the ribbon into pieces that are 2 5 of a yard long. How many pieces of ribbon can she cut?
Answer: The number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards
Step-by-step explanation:
Given: The length of the ribbon = [tex]5\dfrac25[/tex] yards
[tex]= \dfrac{5\times5+2}{5} =\dfrac{27}{5}[/tex] yards
Length of each piece = [tex]\dfrac25[/tex] yards
The number of identical pieces can be cut from the entire ribbon = (Length of the ribbon ) ÷ (Length of each piece )
[tex]=\dfrac{27}{5}\div\dfrac{2}{5}\\\\=\dfrac{27}{5}\times\dfrac{5}{2}\\\\=\dfrac{27}{2}\\\\=13\dfrac12[/tex]
Hence, the number of pieces of the ribbon she can cut = [tex]13\frac12[/tex] yards
Taylor can clean pools at a constant rate of 2/5 pools per hour. What is the ratio of pools to hours?
Answer:1/25
Step-by-step explanation:
1/25 = (2/5)/p. This can be solved by cross-multiplying: p = 25(2/5) = 10. He can clean 10 pools in 25 hours.

Find the angle of XZY
Answer:
23.6°Step-by-step explanation:
to understand the solving stepsyou need to know abouttrigonometry i.g sin(x)=opp/hypoPEMDASgiven:opp:6hypo:15to find:xyz anglelet's solve:[tex]let \: xyz \: angle \: be \: \alpha [/tex]
[tex]according \: to \: the \: question[/tex]
[tex] \sin( \alpha ) = \frac{xy}{zy} [/tex]
[tex] \sin( \alpha ) = \frac{6}{15} [/tex]

Answer:
I beleive the answer is 8
Step-by-step explanation:
4+4=8
The probability that the female kittens are together, and all the male kittens are together is 1/35.
What is Permutation?Permutation is defined as the calculation of a set such that it defines the number of ways that something can be arranged.
Let A represents the arrangements of 8 kittens which includes 4 male and 4 female.
N(A) = 8P₈ / (4! × 4!) = 8! / (4! × 4!) = 70
Let B represents the arrangement of kittens such that 4 males are together and 4 females are together.
N(B) = 2
Probability of arranging kittens in such a way that all the female kittens are together, and all the male kittens are together = 2/70 = 1/35
Hence the required probability is 1/35.

The function y = x 2 - 10x + 31 has a ____
value of ____.
options for the first blank -
A. maximum
B. minimum
options for the second blank -
A. 31
B. 10
C. 6
D. 5
Answer:
Option B. minimum is correct for the first blank
Option C. 6 is correct for second blank.
Step-by-step explanation:
In order to find the maxima or minima of a function, we have to take the first derivative and then put it equal to zero to find the critical values.
Given function is:
[tex]f(x) = x^2-10x+31[/tex]
Taking first derivative
[tex]f'(x) = 2x-10[/tex]
Now the first derivative has to be put equal to zero to find the critical value
[tex]2x-10 = 0\\2x = 10\\x = \frac{10}{2} = 5[/tex]
The function has only one critical value which is 5.
Taking 2nd derivative
[tex]f''(x) =2[/tex]
[tex]f''(5) = 2[/tex]
As the value of 2nd derivative is positive for the critical value 5, this means that the function has a minimum value at x = 5
The value can be found out by putting x=5 in the function
[tex]f(5) = (5)^2-10(5)+31\\=25-50+31\\=6[/tex]
Hence,
The function y = x 2 - 10x + 31 has a minimum value of 6
Hence,
Option B. minimum is correct for the first blank
Option C. 6 is correct for second blank.

solve for x
350 = 25(x+4)
Answer:
Step-by-step explanation:
I'm just going to reverse the equation because I'm more comfortable with the x being on the left side:
25(x+4) = 350
Do distributive property (I'll explain down below if you don't know what that is):
25x+100=350
Same to both sides
25x = 250
Divide 25 on both sides
x = 10
Distributive property is when there are multiple terms inside the parenthesis and 1 or more term outside of it

The vertices of a polygon are (12, 24), (27, 24), (30, 12), and (6, 12). Find the area of the polygon.
Answer:
234
Step-by-step explanation:
A(12, 24), B(27, 24), C(30, 12), and D(6, 12)
A and B have same y value of 24, AB // x axis
C and D have same y value of 12, CD // x axis
AB // CD
AB distance = 27 - 12 = 15
CD length = 30 - 6 = 24
AB ≠ CD ABCD is a trapezoid
Area of trapezoid: (upper base + lower base) x height / 2
height = y difference of A and D or B and C 24 -12 = 12
Area = (15 + 24) x 12 / 2 = 39 x 12 / 2 = 234
