How many days are in a school year? (HINT there are 8 hours in a school day and one school year has 180 days) A 4320 B 8760 C 2920 D 1440
d. 1440
I'm guessing you mean hours in a school yr
8 hrs in a day x 180 days = 1440 hrs in 1 school yr
how many 'hours' are there in a school year?
answer: D
8 hours a day x 180 days ( one school year)
8 x 180
= 1440 hours

What is the sum of 2/3 + (-1/3) in fraction form?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{1}{3}}}}}} [/tex]
Step-by-step explanation:
[tex] \sf{ \frac{2}{3} + ( - \frac{1}{3} )}[/tex]
We know that [tex] \sf{( + ) \times ( - ) = ( - )}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{2}{3} - \frac{1}{3}} }[/tex]
While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same.
[tex] \dashrightarrow{ \sf{ \frac{2 - 1}{3}}} [/tex]
[tex] \dashrightarrow{ \boxed{ \sf{ \frac{1}{3}}}} [/tex]
Hope I helped!

The sum of 2/3 + (-1/3) in fraction form is 1/3 after applying the arithmetic operation, the answer would be 1/3.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The number expression is:
= 2/3 + (-1/3)
= 2/3 - 1/3
Taking 3 as LCM
After simplification:
= (2 - 1)/3
= 1/3
Thus, the sum of 2/3 + (-1/3) in fraction form is 1/3 after applying the arithmetic operation, the answer would be 1/3.

The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8), what are
the coordinates of B?
Answer:
Step-by-step explanation:
(x - 3)/2= 1
x - 3 = 2
x = 5
(y - 8)/2 = -2
y - 8 = -4
y = 4
(5, 4) coordinates for B
The coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]
It is given that:
The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8).
Let the coordinate of B is (x, y)
From the midpoint theorem:
(x - 3)/2= 1
x - 3 = 2
x = 5
For y coordinate:
(y - 8)/2 = -2
y - 8 = -4
y = 4
(5, 4) coordinates for B
Thus, the coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),

Two lines in a plane intersect at a point
A. Two lines in a plane intersect
B. Two lines intersect at a point
C. A point exists
D. Points are in a plane
The statement "Two lines intersect at a point" is a correct option (B) that would be the best choice.
What are the null hypothesis and alternative hypothesis?The null and alternative hypotheses are two generalizations about a population that are strictly contradictory. The null hypothesis can be denoted by H₀ and the alternative hypothesis can be denoted by H₁.
It is given that:
If the statement is rewritten as a conditional statement in if-then form.
As we know,
From the definition of the hypothesis.
The null and alternative hypotheses are two generalizations about a population that are strictly contradictory
The hypothesis is best described as two lines intersecting at a point if the original sentence is restated as a conditional statement in the if-then format.
Thus, the statement "Two lines intersect at a point" is the correct option (B) that would be the best choice.

6) The rectangle below has a perimeter of 46. Find its area:
Answer:
Step-by-step explanation:
Perimeter= 46
Area of rectangle= Length * Width
Ratio = 2 : 1
= Length= 2/3 * 46 = 30.6/2 = 15.3
Width = 1/3 * 46 = 15.3/2 = 7.65
Area= 117.045
A scientist records the number of deer observed in three areas of a forest. The table shows her observations. Area A 18 miles 162 deer. Area B 17 miles 153 deer. Area C 26 miles 234 deer. How many deer per square mile did the scientist observe in the forest?
9 deer per square mile
There are 9 deer per square mile because once you add all of the miles together it equals 61. Then you add all of the deer seen together equaling 549. You then divide 549 by 61 equaling 9.

If 3^1-x +3^1+x = 90, Find the value of x
Answer:
[tex]x=\log_3{(15+ 4\sqrt{14})}\approx3.0949\text{ or } \\x=\log_3{(15- 4\sqrt{14})}\approx-3.0949[/tex]
Step-by-step explanation:
So we have the equation:
[tex]3^{1-x}+3^{1+x}=90[/tex]
First, note that this is the same as:
[tex]3\cdot 3^{-x}+3\cdot 3^x=90[/tex]
Factor out a 3:
[tex]3(3^{-x}+3^{x})=90[/tex]
Divide both sides by 3:
[tex]3^{-x}+3^x=30[/tex]
Change the negative exponent into a fraction:
[tex]\frac{1}{3^x}+3^x=30[/tex]
Multiply both sides by 3^x:
[tex]3^x(\frac{1}{3^x}+3^x)=(30)(3^x)[/tex]
Distribute:
[tex](1)+(3^x)^2=30(3^x)[/tex]
Let u equal 3^x. So:
[tex]1+u^2=30u[/tex]
Subtract 30u from both sides:
[tex]u^2-30u+1=0[/tex]
This is a quadratic. Solve using the quadratic formula. A is 1, b is -30, and c is 1. So:
[tex]u=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Substitute:
[tex]u=\frac{-(-30)\pm \sqrt{(-30)^2-4(1)(1)}}{2(1)}[/tex]
Simplify:
[tex]u=\frac{30\pm \sqrt{900-4}}{2}[/tex]
Subtract:
[tex]u=\frac{30\pm \sqrt{896}}{2}[/tex]
Simplify:
[tex]u=\frac{30\pm 8\sqrt{14}}{2}[/tex]
Simplify:
[tex]u=15\pm 4\sqrt{14}[/tex]
Substitute back u:
[tex]3^x=15\pm 4\sqrt{14}[/tex]
Take the log to base 3 of both sides:
[tex]\log_3{3^x}=\log_3{15\pm 4\sqrt{14}}[/tex]
The left side cancels:
[tex]x=\log_3{15\pm 4\sqrt{14}}[/tex]
So, our solutions are:
[tex]x=\log_3{(15+ 4\sqrt{14})}\approx3.0949\text{ or } \\x=\log_3{(15- 4\sqrt{14})}\approx-3.0949[/tex]
And we're done!
