Answer:
14.375 Or 115/8
Step-by-step explanation:
since 8 7/8 = 71/8 and 7 5/6 = 47/6 and 2 1/3 = 7/3
then 71/8 + ( 47/6 - 7/3) = 115/8

For the circle with the diameter of 7cm, the area is about 38.48cm and the circumference is about 22cm
For the circle with the diameter of 5cm, the area is about 19.63cm and the circumference is about 15.7cm
Step-by-step explanation:
The formula to find the area of a circle is pi*r^2
The formula to find the circumference is 2*pi*r
r = radius, which can be determined simply by taking the diameter, and dividing it by 2.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
x + y = 1 be equation (1)
2x - 3y = -30 be equation (2)
Multiply equation (1) by 2 , we get
2x + 2y = 2 be equation (3)
Subtracting equation (2) from equation (3) , we get
5y = 32
Divide by 5 on both sides , we get
y = 32/5
Hence , the equation is solved and y = 32/5

Cody's school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 13 child tickets for a total of $111. The school took in $156 on the second day by selling 12 senior citizen tickets and 9 child tickets. What is the price each of one senior citizen ticket and one child ticket?
The price of one senior citizen ticket is $7 and the price of one child ticket is $8.
What are the linear equations that represent this question?s + 13c = 111 equation 1
12s + 9c = 156 equation 2
Where:
c = price of one child ticket s = price of one senior citizen ticket What is the price of one children's ticket?Multiply equation 1 by 12
12s + 156c = 1332 equation 3
Subtract equation 2 from equation 3
1176 = 157c
c = $8
What is the price of one senior citizen's ticket?
Substitute for c in equation 1:

A triangle has sides with lengths of 31 feet, 72 feet, and 78 feet. Is it a right triangle?
yes
no
=========================================================
Explanation:
We have a triangle with these side lengths
a = 31b = 72c = 78The order of 'a' and b doesn't matter, but we must have c as the largest value. Usually a,b,c are in ascending order.
Plug those values into the formula for the pythagorean theorem. If we get the same thing on both sides, then we have a right triangle.
[tex]a^2 + b^2 = c^2\\\\31^2 + 72^2 = 78^2\\\\961+5184 = 6084\\\\6145 = 6084\\\\[/tex]
We have a false statement at the end, which means the original equation is false for those a,b,c values.
Therefore, we do not have a right triangle.
Instead, this triangle is acute since the [tex]a^2+b^2[/tex] side is larger than the [tex]c^2[/tex] side
---------------
Rules to have in your notebook or on a reference sheet:
[tex]\text{If }a^2 + b^2 = c^2 \text{ then it is a right triangle}\\\\\text{If }a^2 + b^2 > c^2 \text{ then the triangle is acute}\\\\\text{If }a^2 + b^2 < c^2 \text{ then the triangle is obtuse}\\\\[/tex]

The person's body temperature will approach 98.6ºF as time lapses, The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses.
What is horizontal asymptote?A horizontal asymptote is known to be that line that is horizontal in nature and it is one that is not an aspect of a graph that has a function but t act as a guides for its x-values.
Note that Horizontal asymptote occurs to T(f) only when t is said to be very large (as it approaches infinity) and thus, it connote that the person's body temperature will be going towards 0ºF above 98.6ºF as t moves to infinity.

Write an equation for the line that has a slope of -2/3 and goes through the point (-6,8)
Answer:
The solution is in the image
Answer:
y = (-2/3)x + 4
Step-by-step explanation:
the equation of a line is given by the formula y = mx + b where m is the slope and b is the y intercept.
so,
y = (-2/3)x + b
to find b we plug in the values of x and y given by the point (-6,8)
8 = 4 + b
b = 4
so y = (-2/3)x + 4
