Answer:
x = 45°
Step-by-step explanation:
the triangle has 2 congruent sides and is therefore isosceles with the base angles being congruent, both x
the sum of the 3 angles = 180° , then
x + x + 90° = 180° ( subtract 90° from both sides )
2x = 90° ( divide both sides by 2 )
x = 45°

[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]
Step-by-step explanation:
Given
[tex]Backpack = 18\frac{7}{9}kg[/tex] --- with math book
[tex]Backpack = 14\frac{7}{8}kg[/tex] --- without math book
Required
Determine the weight of her math book
To do this, we simply calculate the difference in the weights given.
Math Book= Backpack(with math book) - Backpack (without math book)
[tex]Math\ Book = 18\frac{7}{9} - 14\frac{7}{8}[/tex]
[tex]Math\ Book = \frac{169}{9} - \frac{119}{8}[/tex]
Take LCM
[tex]Math\ Book = \frac{8 * 169 - 9 * 119}{72}[/tex]
[tex]Math\ Book = \frac{1352 - 1071}{72}[/tex]
[tex]Math\ Book = \frac{281}{72}[/tex]
[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]

The required value of function p(x) at x = -7, p(-7) is zero.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
As given that one factor of a polynomial p(x) is (x + 7).,
Since factor x, + 7 also represents one of the zeros of a polynomial function p(x).
So, when one put the value x = -7 in the function, the function gives zero in the outcome.
Thus, the required value of function p(x) at x = -7, p(-7) is zero.

A phone company has two long distance plans. Plan A charges a flat monthly fee of $13 and $0.37 per minute of long distance calls Plan B charges a flat monthly fee of $28 and $0.15 per minute of long distance calls. After how much time on long distance calls to the nearest minute, would the cost of plan A be equal to the cost of plan B?
Answers
Answer:
68.18minStep-by-step explanation:
let the cost of plan A be Y1
and the cost of plan B be Y2
let the number of minutes for both plans be x
let us model the cost of plan A
Y1= 13+0.37x-------1
let us model the cost of plan B
Y2= 28+0.15x------2
when Y1=Y2, we can now solve for x which is in minutes
13+0.37x=28+0.15x
collect like terms
13-28=0.15x-0.37x
-15=-0.22x
divide both sides by -0.22
x=-15/-0.22
x=68.18min

Answers
Answer:
Step-by-step explanation:
Answer: 3=b
Step-by-step explanation:
First get the like terms 3 and (-3) on one side.
You do this by either adding or subracting, it depends on the sign of the number. -3 is negative 3 but you have to add it to make it zero and on the other side you add it and get 6.
Then you divide 6 by 2. 2b by 2 to get the variable alone and 3=b is your answer.
