Answer:
The answer 26, given that it’s atomic number is 26, and the atomic number is equal to the number of protons, which is equal to the number of electrons. Assuming that it has a neutral charge, the answer would be 26.
Step-by-step explanation:
Find the measure of the missing angles.
Helpp
x = 90 ( supplementary angle )
y = 180 - ( 90+ 26)
= 180 - 116

1.45 rounded to the nearest hundredth
Answer:
1.45
Step-by-step explanation:
1.45 is already rounded to the nearest hundredth..
Answer:
1.45 (no need to round)
Step-by-step explanation:
When looking at this question we can clearly see that there are only 2 numbers behind the decimal.
We know that the number closet to the decimal is the tenths place.
And that the number second closet to the decimal is the hundredths place.
And that the number third closet to the decimal is the thousandths place.
Since there is no thousandths place we can't round the 5 up.
Which is why your answer is 1.45

what is the solutions by solving by quadratic equations
Answer:
x = - 4
Step-by-step explanation:
Given
- x² - 8x - 16 = 0 ( multiply through by - 1 to clear the leading negative )
x² + 8x + 16 = 0 ← this is a perfect square
(x + 4)² = 0 ( take the square root of both sides )
x + 4 = 0 ( subtract 4 from both sides )
x = - 4

If you apply the changes below to the absolute value parent function, fx) = x
what is the equation of the new function?
• Shift 5 units to the left.
• Shift 4 units down.
A. g(x) = 5x + 41 - 5
B. g(x) = 1x - 51 - 4
C. g(x) = 5x + 51 - 4
D. g(x) = 1x - 41 - 5
The required function after shifting its origin will be g(x) = |x + 5| - 4.
What is Shifting of Origin?
To shift the coordinates of origin to (h,k): Replace x by (x-h) and y by (y-k) in the given equation and get the new equation.
Here, given function f(x) = |x|
or y = |x|
Now, Shift 5 units to the left. x replaces with x - (-5) = x + 5
Shift 4 units down, y replaces with y -(-4) = y + 4
Now equation after shifting ,
y - k = | x - h|
y = |x -h| + k
y = |x - (-5)| +(-4)
g(x) = |x+5|-4
Thus, The required function after shifting its origin will be g(x) = |x + 5| - 4.

This question is confusing me
Answer:
She went on the slide 8 times and on the roller coaster 4 times
Step-by-step explanation:
We convert each statements to a mathematical equation.
Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.
Mathematically, R + S = 12. ........(i)
Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.
To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.
Mathematically, 25R + 10S = 180 .......(ii)
Here we now have two equations that we can solve simultaneously.
From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:
25(12 - s) + 10s = 180
300 - 25s + 10s = 180
300 - 25s + 10s = 180
300 - 15s = 180
15s = 300 - 180
15s = 120
S = 120/15
S = 8
S = 8 , and R = 12 - S = 12 - 8 = 4

we can see that there are already answers for 2 which is six 6+6=12 now we can see that a triangle look the same as the six over the 8mm so that must be six so 6+6+6=18 now there is still s little section missing over the 8mm (the half triangle half square) is missing a section we can see that the perimeter is 8 and the area is 6 and 6+2=8 so that little area is 2 so 6+6+6+2=20

The lengths of the two diagonals of a rhombus are 6 cm and 8 cm. Find the length of its perimeter (in
cm)
Answer:
The perimeter of the rhombus is 20 cm
Step-by-step explanation:
Perimeter of a Rhombus
Given the lengths of the two diagonals of a rhombus, let's call them a and b, the perimeter of the rhombus is given by:
[tex]P=2\sqrt{a^2+b^2}[/tex]
The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:
[tex]P=2\sqrt{6^2+8^2}[/tex]
[tex]P=2\sqrt{36+64}[/tex]
[tex]P=2\sqrt{100}=2*10[/tex]
[tex]P=20\ cm[/tex]
The perimeter of the rhombus is 20 cm

Write an equation for the line that passes through (10, 17) and (20, 37)
T = L(8 + RS)
Solve for R
Answer:
Step-by-step explanation:
T=L(8+RS)
T=L8+LRS
T-L8=LRS
R=T-L8/LS
The required solution to the given equation is R = (T - 8L)/LS.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
T = L(8 + RS)
Apply the distributive property of multiplication,
T = L × 8 + L × RS
T = 8L + LRS
Rearrange the terms in the above equation,
T - 8L = LRS
Divided by LS into both sides, and we get
R = (T - 8L)/LS
Thus, the required solution to the given equation is R = (T - 8L)/LS.

Three consecutive odd numbers sum to 1,245. What are the three numbers?
Answer:
413, 415, 417
Step-by-step explanation:
Answer:
414, 415, 416
Step-by-step explanation:
Consecutive numbers means they come one after another, like 1,2,3,4,5... So they all follow the formula x, x+1, x+2, x+3...x+n.
Since there are 3, we can say that x+(x+1)+(x+2)=1,245.
Simplify that to 3x+3=1,245, and then subtract 3 from both sides.
We get 3x=1,242. Divide that by 3, and you get x=414.
Add 1 and 2 to 414, and you get 414, 415, and 416.
You can add them up to check.
The three sides of a triangle are represented by 6x – 1, 5x + 16, and 3x + 40. Express the perimeter, in terms of x.
Answer-
Step by step explanation:
We know that perimeter of a triangle is equal to sum of the sides of a triangle.
So, we need to add the sides,
(6x - 1) + (5x + 16) + (3x + 40) = Perimeter of triangle
6x - 1 + 5x + 16 + 3x + 40
14x + 55
Hence, 14x + 55 is the perimeter of triangle.
