I need help with these problems
Step-by-step explanation:
whenever you see a variable ( a letter ) without a number in front of it, add a 1 ! It means the same thing...
y is the same as 1y
1). 3y + y = ?
Add that 1!
3y + 1y = ?
This problem is the same as 3 + 1
3y + 1y = 4y
2). b + b = ?
Add those 1's !
1b + 1b = ?
this is the same as 1 + 1
1b + 1b = 2b
Remember to keep the variable !
Part B is like a puzzle and the instructions give us hints.
It is telling us, when we see an r, we replace it with the number 3
and when we see t , we replace it with the number 9
Let's solve these puzzles!
8). [tex]\frac{r}{t} = ?[/tex]
We see and r and a t, let's plug in 3 and 9
Now we have ...
[tex]\frac{3}{9} = ?[/tex]
Divide using a calculator!
We get ....
[tex]\frac{3}{9} = \frac{1}{3}[/tex] or 0.33
9). [tex]rt = ?[/tex]
When variables are right next to each other, this means they are being MULTIPLIED!
Let's replace r and t with 3 and 9 and multiply them together!
[tex]rt =[/tex] 3 × 9
3 × 9 = 27
We do similar things for Part C
12). [tex]ab = ?[/tex]

Express 2678 as a product of prime numbers
Answer:
2, 13, 103
Step-by-step explanation:
These prime numbers are the ones.
2678 = 2 * 13 * 103
A prime number is a natural number that is greater than one and is not a product of smaller natural numbers. For example, 3 is a prime number and we can write it as a product, 1 * 3 or 3 * 1, which involves 3 itself.
So, prime numbers are those numbers that have only two factors, which are 1 and the number itself.
A natural number that is greater than 1 and is not a prime number, is called a composite number. Every natural number which is greater than 1, is either a prime itself or can be factorized as a product of primes that is unique up to their order.
The answer is -
2678 = 2 * 13 * 103

If you are given an equation of a line
and a set of points, and are asked to find
an equation that is perpendicular to Line
#1, what do you need to do?
If you are given an equation of a line and a set of points, you should determine the slope of the equation that is perpendicular to the given equation of line. Lastly, you should use the set of points to write an equation for the perpendicular line.
How to determine an equation of this line?Mathematically, the slope-intercept or standard form of the equation of a straight line is given by this mathematical expression;
y = mx + c
Where:
m represents the slope.x and y are the points.c represents the y-intercept.In Mathematics, a condition that must be met for two lines to be perpendicular is given by this mathematical expression:
m₁ × m₂ = -1
Assuming the given equation of a line is y = 2x, the slope of the equation that is perpendicular to this line would be calculated as follows;
m₁ × m₂ = -1
2 × m₂ = -1
Slope, m₂ = -1/2.
In conclusion, you will use the newly calculated slope alongside the set of points to determine the equation for the perpendicular line either by using the slope-intercept form or point-slope form.

David invests $800 into an account with a 2.3% interest rate that is compounded semiannually.
How much money will he have in this account if he keeps it for 5 years?
Round your answer to the nearest dollar.
To calculate how much money David will have in this account after 5 years, we first need to find out how much interest the account earns each year. To do this, we need to multiply the interest rate by the amount of money in the account. In this case, the interest earned each year would be $800 * 0.023 = $18.40.
Next, we need to calculate how much interest the account earns over the 5-year period. Since the interest is compounded semiannually, this means that the interest is earned twice per year. Therefore, the total amount of interest earned over 5 years would be $18.40 * 2 * 5 = $184.
Finally, we need to add the interest to the original amount of money in the account to find out how much money David will have after 5 years. In this case, the total amount of money David will have after 5 years is $800 + $184 = $984.
Therefore, if David keeps the money in this account for 5 years, he will have $984.
Answer:

We know:
P = 800

The perimeter of the figure with side length of 5 units is 50 units
How to determine the perimeter of the figureFrom the question, we have the following parameters that can be used in our computation:
Shape = rectangle
Smaller shapes = squares
Side lengths = 5 units
The perimeter of the figure is calculated as
Perimeter = Number of visible sides * Side length of the square shape
In this case, we have
Number of visible sides = 10
Substitute the known values in the above equation, so, we have the following representation
Perimeter = 10 * 5

Last year at a certain high school, there were 56 boys on the honor roll and 135 girls on the honor roll. This year, the number of boys on the honor roll increased by 25% and the number of girls on the honor roll increased by 20%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
There is an effective change of 50% in the school.
What is Percentage?
A percentage is a relative figure that represents the hundredth part of any amount. One percent (symbolised 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.
Solution:
To find the net/effective change we can the use the formula:
(a + b + ab/100)
here a and b are the rate of change
a = 25% and b = 20%
Net change = (25 +20 + 500/100) = 45 + 5 = 50%

Answer:

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 4 ) and (x₂, y₂ ) = (4, 2 )
m = [tex]\frac{2-(-4)}{4-(-1)}[/tex] = [tex]\frac{2+4}{4+1}[/tex] = [tex]\frac{6}{5}[/tex] ← slope of graphed line
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{6}{5} }[/tex] = - [tex]\frac{5}{6}[/tex] , then
y = - [tex]\frac{5}{6}[/tex] x + c ← is the partial equation of the perpendicular line
to find c substitute (- 3, 7 ) into the partial equation
7 = [tex]\frac{5}{2}[/tex] + c ⇒ c = 7 - [tex]\frac{5}{2}[/tex] = [tex]\frac{14}{2}[/tex] - [tex]\frac{5}{2}[/tex] = [tex]\frac{9}{2}[/tex]
y = - [tex]\frac{5}{6}[/tex] x + [tex]\frac{9}{2}[/tex] ← equation in slope- intercept form
multiply through by 6 ( the LCM of 6 and 2 ) to clear the fractions
6y = - 5x + 27 ( add 5x to both sides )
5x + 6y = 27 ← equation of perpendicular line in standard form

Answer:
For the first one x= 60 degrees
Second one x= 125 degrees
Step-by-step explanation:
a) To figure out this we can see that the total of angles in a 5- angled shape is 540 degrees.
So (2x X 4) + x = 540 degrees
= 9x= 540
= x = 60
b) To figure out this we can see that the total of angles in a 7- angled shape is 900 degrees.
So 60+2x+x+x+x+x+90= 900
= 150 +6x= 900
= 6x= 750
= x= 125

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint M is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula
calculate the midpoint of PR using this formula and equate x and y coordinates to the coordinates of the given midpoint
let coordinates of R be (x, y ) and P = (- 15, 4 ) , then
[tex]\frac{x-15}{2}[/tex] = - 6 ( multiply both sides by 2 )
x - 15 = - 12 ( add 15 to both sides )
x = 3

Area of rectangle = 50
Answer:
x = 3.66
Step-by-step explanation:
Area of a rectangle = length * width
In this case:
(x+10)x = 50
x*x + x*10 = 50
x² + 10x - 50 = 0
x = {-10±√((10²) -(4*1*-50))} / (2*1)
x = {-10±√(10² + 200)} / 2
x = {-10±√(100+200)} / 2
x = {-10±√300} / 2
x = {-10±17.321} /2 aprox,
It is a geometric figure so only the positive value is taken.
x = {-10+17.321} / 2
x = 7.321/2
x = 3.66

3.66*13.66 = 50

What is Acceleration ?
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
Given,
Velocity v= x² − 5x + 4
now, the acceleration
a = dv/dt
a = 2x (dx/dt) - 5x(dx/dt)
given that, v= dx/dt =0
so, a = 2x*0−5*0
a=0 m/sec²
