Answer:
In a triangle, all the angles add up to 180 degrees. The square in the bottom left of the triangle shows that it is a right angle or 90 degrees. So you have two angles and you subtract them both from 180.
180-42-90=48
So your answer is 48 degrees.
Write an
explicit formula for an, the nth term of the sequence 5, 15, 25, ....
Given:
The sequence is 5, 15, 25, ... .
To find:
The explicit formula for the nth term of the given sequence.
Solution:
We have,
5, 15, 25, ...
It is an AP because the difference between two consecutive terms are same.
Here,
First term : a = 5
Common difference : d = 15 - 5 = 10
Now, the explicit formula for the nth term of an AP is
[tex]a_n=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
[tex]a_n=5+(n-1)10[/tex]
[tex]a_n=5+10n-10[/tex]
[tex]a_n=10n-5[/tex]
Therefore, the required explicit formula for the given sequence is [tex]a_n=10n-5[/tex].

r =
Step-by-step explanation:
11.75 + 3.50r = 52
- 11.75 -11.75
3.50r = 40.25
÷3.50 ÷3.50
r= 11.5
We round down to 11 since you cannot buy half of a rose.
A cellphone company charges you $17 a month plus $0.25 for each text message you send. The total bill last month was $45.50. Which of the following equations could you use to figure out how many text messages you sent?
17x - 0.25 = 45.50
17x + 0.25 = 45.50
17 - 0.25x = 45.50
17 + 0.25x = 45.50

Q6. A colony of ants is beg please help, I don’t know this and I have to hand it in in 20 mins
increases exponentially at a rate of 10% per week. Initially there are 500
ants.
a) Show that the number of ants in the colony forms a geometric progression
b) The number of ants in week 8 is p times greater than in week 6. Find the value of p.
Answer:
a) The number of ants in week three is shown through the following geometric progression: 500*1.1*1.1*1.1
b) 1.21
Step-by-step explanation:
We know that 500 ants are increasing at a rate of 10% every week which means that we can calculate the week one ants like this
500*1.1
Week two
500*1.1*1.1
and so on.
We write the following equation
500(1.1)^n where n is the number of weeks
We plug in 8 and then 6 for n in the equation above and get
500(1.1)^8=1071.79
500(1.1)^6=885.78
Divide and get that p=1.21

and please show your work so I can learn
Hello there,
I hope you and your family are staying safe and healthy during this winter season.
[tex]x^2 + y^2 -6x+14y-1=0[/tex]
We need to use the Quadratic Formula*
[tex]x =\frac{-b+\sqrt{b^2}-4ac }{2a}[/tex] , [tex]\frac{-b-\sqrt{b^2} -4ac }{2a}[/tex]
Thus, given the problem:
[tex]a = 1, b=-6, c=y^2+14y-1[/tex]
So now we just need to plug them in the Quadratic Formula*
[tex]x=\frac{6+2\sqrt{(-6)^2-4(y^2+14y-1)} }{2}[/tex] , [tex]x=\frac{6-\sqrt{(-6)^2-4(y^2+14y-1)} }{2}[/tex]
As you can see, it is a mess right now. Therefore, we need to simplify it
[tex]x=\frac{6+2\sqrt{10-y^2-14y} }{2}[/tex], [tex]x = \frac{6-2\sqrt{10-y^2-14y} }{2}[/tex]
Now that's get us to the final solution:
[tex]x=3+\sqrt{10-y^2-14y}[/tex], [tex]x=3-\sqrt{10-y^2-14y}[/tex]

Can someone help me understand where the positive 2 came from?
Answer:
4(-2)-(0)-2(-1)
a negative number multiplied by a negative number will always equal a positive number as the two negatives cancel each other out.
-2 multiplied by -1 equals positive 2
this is why the 2 is positive.

Answer:
-81
Step-by-step explanation:
-6(2x² + 5x) - 9
substitute -4 for 'x'
-6[2(-4)² + 5(-4)] - 9
-6[2(16) + (-20) - 9]
-6(32 - 20) - 9
-6(12) - 9

The value of m is 7 in the equation [tex]-5m = -35.[/tex]
The given equation is [tex]-5m = -35[/tex].
In the equation, the variable is m.
To find the value of m, divide both sides by 5:
[tex]-m=-\frac{35}{5}[/tex]
[tex]-m=-7[/tex]
The minus sign on both sides will be cancelled.
[tex]m=7[/tex]
Hence, the value of m is 7 in the equation [tex]-5m = -35.[/tex]

A picture frame is shaped like a rectangle whose perimeter is 140 cm. The length is 4 times as long as the width. Find the length and the width.
Answer:
L= 56cm
W= 14cm
Step-by-step explanation:
Given data
Perimeter of the frame= 140cm
Let the width be
W=x cm
Length= 4x
We know that
P= 2L+2W
subsitute
140= 2(4x)+2(x)
140 = 8x+2x
140= 10x
Divide both sides by 10
x= 140/10
x= 14cm
The length is
L= 4(14)
L= 56cm

The bookstore has 4 women's magazines and 76 other magazines. What percentage of the magazines at the bookstore are women's magazines?
This question is dealing with fractions and percentages.
Fractions and percentages are just means of expressing a part of a whole portion.
percentage of magazines that belong to women is = 5%
Number of women magazines = 4
Number of other magazines = 76
Total number of magazines = 4 + 76 = 80
Therefore,
percentage of magazines that belong to women is; [tex]\frac{4}{80}[/tex] × 100
percentage of magazines that belong to women is = 5%

Prove that the sum of the squares of two consecutive integers is odd
Answer:
Step-by-step explanation:
Start by breaking up the question into parts:'always an odd number' . An even number is any number divisible 2 e.g. 2n, an odd number is always 1 higher or lower than an even number e.g. 2n+1 or something similar. Getting an answer at the end of working of this form will prove the theory'any two consecutive integers' means two numbers that are next to each other on the number line.To prove this, we can do this in terms of n i.e. n and n+1'the squares' square the two terms we have just written down to give n2 and (n+1)2The 'sum of the squares' tells us to add these two parts together. We would then hope to work through this and get something similar to the idea of 2n+1 or something similarn2+(n+1)2=2n2+2n+1=2(n2+n) +1. The first part of this is even because it is divisible by 2. By adding 1 it must become odd.
Answer: Every even number can be expressed in the form (2n) where n is an integer. So we have an even number, 2n, and an odd number, 2m+r. Adding them together we get 2n + 2m + r, which can be expressed as 2 (n+m) + r.
