Sharon skated for 6 2/3 hours last month and 2 2/3 hours this month. How many hours did Sharon skate in all?
Answer:
9 1/3
Step-by-step explanation:
6 2/3 + 2 2/3 = ?
6 + 2 = 8
2/3 + 2/3 = 4/3 = 1 1/3
8 + 1 1/3 = 9 1/3
Sharon skated for 9 1/3 hours.

find constants p and q such that x^4-2x^3-x^2+2x+10=(x^2+px+5)(x^2+qx+2)
Answer:
p = -4 q = 2
Step-by-step explanation:
Expand the brackets ( yes the entire thing).group together the values with same co-effiecients; like (q+p)x^3 etc etc.equate the co-effiecients on the left hand side to the now grouped ones on the right, for example [x^3]: -2x^3= (q+p)x^3, the x^3 cancels and ull get an equation only in terms of p and q. do the same for [x] and ull get an equation with only q, solve this and get the value for q [q = 2].sub in this value for the [x^3] equation and ull get an answer for p [p= -4].hope my explanation is understandable lol
You rub a balloon on your head and it becomes negatively charged. The balloon will be most attracted to
Answer:
When you rub the balloon on your hair, the balloon becomes negatively charged because it gains electrons from your hair.
Step-by-step explanation:
Is it multiple choice? If not the answer is anything positively charged. Negative and positive ions attract, while synonymous (N,N or P,P) repel. Pieces of paper, the wall, or even your clothing are all possibly positive charged objects the balloon could stick to.
Express the height of the tower in terms of trigonometric ratios. A) 35(cos95°) B) 95(tan35°) C) 95(cot35°) D) 95(sin35°)
Answer:
95tan35°
Step-by-step explanation:
Find the diagram attached
Given the following
Adjacent = 95m
Opposite = height of the tower
Angle of elevation = 35degrees
Using SOH CAH TOA
tan theta = opp/adj
Tan 35 = h/95
Cross multiply
95 * tan 35 = h
95tan35 = h
Swap
h = 95tan35
Hence then the height of the tower in terms of trigonometric ratios is 95tan35°

Question 1: Imagine that we are measuring rain fall with a rain gauge. It is raining
at a rate of 1.25 inches per hour and after 5 hours, there are 6 inches of rain in the
gauge.
How much rain will be in the gauge in 11 hours
Answer:
13.5 inches
Step-by-step explanation:
after 5 hours = 6 inches
11 - 5 = 6 hours to go
1.25 x 6 = 7.5 inches
7.5 + 6 = 13.5 inches

Answer:
[tex]\sqrt{180}[/tex] and [tex]6\sqrt{5}[/tex]
Step-by-step explanation:
The easiest way to solve this problem is to look at all the simplified radicals on the right. Then un-simplify them by bringing the coefficients under the radical. If the radican (value under the radical) of the radical on the right is equal to the radican on the left, then the two radicals are equal.
To un-simplify a radical, one will square the coefficients and then multiply that value by the current radican of expression. The result is the un-simplified value of the radical.
A.
[tex]3\sqrt{15}\\\\= \sqrt{15*(3)^2}\\\\=\sqrt{15*9}\\\\=\sqrt{135}[/tex]
[tex]\sqrt{45} \neq \sqrt{135}\\\sqrt{45} \neq 3\sqrt{15}[/tex]
B.
[tex]3\sqrt{5}\\\\=\sqrt{5*(3)^2}\\\\=\sqrt{5*9}\\\\=\sqrt{45}[/tex]
[tex]\sqrt{75} \neq \sqrt{45}\\\sqrt{75} \neq 3\sqrt{5}[/tex]
C.
[tex]9\sqrt{6}\\\\=\sqrt{6*(9)^2}\\\\=\sqrt{6*81}\\\\=\sqrt{486}[/tex]
[tex]\sqrt{54} \neq \sqrt{486}\\\sqrt{54} \neq 9\sqrt{6}[/tex]
D.
[tex]6\sqrt{5}\\\\=\sqrt{5*(6)^2}\\\\=\sqrt{5*36}\\\\=\sqrt{180}[/tex]
[tex]\sqrt{180}=\sqrt{180}\\\sqrt{180}=6\sqrt{5}[/tex]

Answer:
B. Larger groups tended to take less time to solve the puzzle
Step-by-step explanation:
If you look at the graph, you can see that farther to the left the dots are higher, which means that the number of people are taking longer than the people to the right of the graph whose dots are lower, representing that it takes less time for the larger groups to solve the puzzle.

An aquarium holds 11.35 cubic feet of water, and is 2.8 feet long and 1.5 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
3 feet
Step-by-step explanation:
the volume of the aquarium is V= Lx wx H
it is as of now given that V=11.25 cubic feet, so 11.25=LxWxH
H tallness and it is the aquarium's profundity
H=11.25/L xW= 11.25/2.5x1.5= 3 feet
Answer:
The depth is 3 ft
Step-by-step explanation:
The equation for volume is V = length * height * depth
change the equation for depth
depth = volume / (length * height)
fill the equation and solve
depth = 11.35 / (2.8 * 1.5)
depth = 11.35 / 4.2
depth = 2.70238095 rounded to 3

3. When should points of intersection be included within the feasible region of a system of nonlinear inequalities
and why
Answer:
Points of intersection should be included within the feasible region (the solution set) of a system of nonlinear inequalities when the boundary lines that create the point are solid. A dashed line indicates that the points are not included in the solution set. Therefore, if one boundary line is dashed and one is solid, the point of intersection will not be included within the feasible region.
Step-by-step explanation:
Points of intersection should be included within the feasible region of nonlinear inequalities when the boundary lines that create the point are solid.
What is Inequality?This is defined as an expression in which the sides are not equal to each other.
The presence of boundary lines which have dashed and solid ones, the point of intersection will not be included within the feasible region.

prove that underroot 3-underroot 5 is irrational.
Please quickly I need this answer
Answer:
See Explanation
Step-by-step explanation:
Let us assume that [tex] \sqrt 3 - \sqrt 5[/tex] is a rational number.
So, it can be expressed in the form of [tex] \frac{p}{q} [/tex] where p and q are integers.
[tex]\therefore \sqrt 3 - \sqrt 5=\frac{p}{q}[/tex]
[tex]\therefore \sqrt 3 =\frac{p}{q}+ \sqrt 5[/tex]
[tex]\therefore \sqrt 3 =\frac{p+q\sqrt 5}{q}[/tex]
Squaring both sides:
[tex] (\sqrt 3) ^2 =\bigg(\frac{p+q\sqrt 5}{q}\bigg ) ^2 [/tex]
[tex]\therefore 3 =\frac{p^2 +5q^2 +2\sqrt 5 pq}{q^2 } [/tex]
[tex]\therefore 3q^2 ={p^2 +5q^2 +2\sqrt 5 pq}[/tex]
[tex]\therefore 0 = p^2 +5q^2 -3q^2 +2\sqrt 5 pq [/tex]
[tex]\therefore - 2\sqrt 5 pq=p^2 +2q^2 [/tex]
[tex]\therefore \sqrt 5 = \bigg (\frac{p^2 +2q^2}{-2pq} \bigg) [/tex]
[tex]\therefore \sqrt 5 = - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex]
Since, p and q are integers so [tex] - \bigg(\frac{p^2 +2q^2}{2pq} \bigg) [/tex] is rational.
[tex]\therefore \sqrt 5 [/tex] is also rational.
But it contradicts the fact that [tex]\sqrt 5 [/tex] is irrational.
Hence, our assumption that [tex] \sqrt 3 - \sqrt 5[/tex] is rational is wrong.
[tex] \therefore \sqrt 3 - \sqrt 5[/tex] is irrational.

josh put some water into his empty swimming pool on Monday then he put an equal amount of water in the pool on Tuesday the pool was then 3/4 full of water how fuel was the swimming pool after josh put the water in on Monday
Answer:
3/8
Step-by-step explanation:
since you can't have 1.5/4, which was how much he Josh put on each day, you have to multiply the denominator and the numerator for a more complex fraction. So 1.5/4 x 2 for both = 3/8.
