Which of the following expressions represents 3 less than 5 times a number
A) 5n - 3
B) 5 - 35
C) 3n - 5
D) 3 - 5
Answer:
A)
Step-by-step explanation:
The correct expression which represents ''3 less than 5 times a number'' would be,
A) 5n - 3
Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that,
A mathematical expression is,
''3 less than 5 times a number''
Let us assume that,
A number = x
Hence, the expression to represent ''3 less than 5 times a number'' is,
⇒ (5 × n) - 3
⇒ 5n - 3
So, the correct option is,
A) 5n - 3

A model rocket is launched with an initial upward velocity of 156ft/s . The rocket's height h (in feet) after seconds is given by the following. h= 156t-16t^2
The values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35
How to determine the values of t for which the rocket's height is 60?The function is given as:
h = 156t - 16t^2
When the height is 60 feet, we have:
156t - 16t^2 = 60
Rewrite as:
16t^2 - 156t + 60 = 0
Divide through the equation by 4
4t^2 - 39t + 15 = 0
Next, we solve the equation using a graphing calculator
From the graphing calculator, we have:
t = 0.40 and t = 9.35
Hence, the values of t for which the rocket's height is 60 feet are t = 0.40 and t = 9.35

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
From the data given the equation can be framed:
The proportional relationship will be:
y ∝ x
y = kx
x = 1 y = 1
k = 1
y = x

Answer:
C. x - y = 0
Step-by-step explanation:
First find write the equation in slope-intercept form, then rewrite to convert to standard form as Ax + By = C.
Equation in Slope-intercept form:
Find m and b
m = rise/run = 1/1 = 1
b = y-intercept = 0 (where the line intercepts the y-axis)
Substitute m = 1, and b = 0 into y = mx + b
Thus:
y = (1)(x) + 0
y = x
Rewrite to convert to standard form.
Thus, the equation in standard form would be:

Answer:
[tex]\approx 91^\circ[/tex]
Step-by-step explanation:
The given equation to represent the model for the relationship between [tex]x[/tex] and [tex]y[/tex].
[tex]y=6.88x-199[/tex]
[tex]x[/tex] represents the air temperature in degrees and
[tex]y[/tex] represents the number of visitors at a pool.
Also given that number of visitors at the pool on a particular day is 426.
To find:
The expected air temperature as per the number of visitors.
Solution:
Here, we are given a linear equation to represent the relation between two variables.
Value of one variable is given and we have to find the value of other variable.
i.e. we are given that:
[tex]y=426[/tex] and we have to find the value of [tex]x[/tex].
Let us put the value in the equation:
[tex]426=6.88x-199\\\Rightarrow 6.88x = 426 + 199\\\Rightarrow x = \dfrac{625}{6.88}\\\Rightarrow \bold{x \approx 91^\circ}[/tex]

Answer:
The reciprocal we use: [tex]\frac{5}{3}[/tex] ; Answer: [tex]\frac{5}{24}[/tex]
Step-by-step explanation:
The reason why we use this reciprocal is because we are dividing 3/5 from 1/8, so we have to use the reciprocal of the divisor instead. Next, we multiply the numerators and denominators and we get the product of 5/24 and since we cannot simplify further, this is the final answer.

Suppose there are two types of tickets to a show: advance and same-day. Advance tickets cost $40 and same-day tickets cost $30. For one performance, there were 65 tickets in all, and the total amount paid for them was $2200. How many tickets of each type were sold?
Advance tickets: represented by x
Same-day tickets: represented by y
you can model this using a system of equations
x + y = 65
40x + 30y = 2200
then you have to get either the x or y value equivalent in both equations
40(x + y = 65)
40x + 40y = 2600
so the new equations are 40x + 40y = 2600 and 40x + 30y = 2200
then you can solve by using elimination
40x + 40y = 2600
-(40x + 30y = 2200)
10y = 400
y = 40
substitute y back into the first equation
x + 40 = 65
x = 25

Every month, Veronica deposits $230 in an account with an interest rate of 6% compounded monthly. How much money will she have in the account at the end of the first 5 years? (Round to the nearest cent. Do not enter the $ sign.)
Answer:
Veronica will have $310.04 at the end of first five years.
Step-by-step explanation:
Principal Amount P = $230
Interest Rate r = 6%
Time t = 5 years
Compounded monthly n = 12
We need to find the future amount (A)
The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values and finding A
[tex]A=P(1+\frac{r}{n})^{nt}\\A=230(1+\frac{0.06}{12})^{5*12}\\A=230(1+0.005)^{60}\\A=230(1.005)^{60}\\A=230(1.348)\\A=310.04[/tex]
So, Veronica will have $310.04 at the end of first five years.
The three angles in a triangle are in the ratio 1:3:5. Find the angles
Answer:
1:3:5
20:60:100
Step-by-step explanation:
angles in a triangle add up to 180
so we add 1,3 and 5 to get 9
to find out how much 1 part is worth we do 180÷9 to get 20
so 1 part=20
so we we do:
20x1=20
20x3=60
20x5=100
Answer:
30:60:100
Step-by-step explanation:
angles of triangle =180°
sum of ratios
1+3+5=9
finding for the first one which is one
1/9×180°=20°
finding for the second one which is three
3/9×180°=60°
finding for the third one which is five
5/9×180=100°
adding all the angles
20°+60°+100°=180°

The main span of Bridge A (2700 feet) is
percent shorter than the main span of Bridge B (4300 feet).
Round to one decimal place
The main span of Bridge A (2700 feet) is 37. 2 % percent shorter than the main span of Bridge B (4300 feet).
The percentage distinction of any 2 numbers is that the worth of the magnitude relation of their distinction and their average increased by a hundred. The word % means that the a part of the amount a hundred. it's a fraction or a magnitude relation wherever the total worth is usually a hundred.
It is providing main span of Bridge A is at a 2700 feet and therefore the main span of Bridge B is at a 4300 feet.
Step 1: realize the distinction between the 2 numbers.
4300 - 2700 = 1600
Step 3: Take the magnitude relation of the distinction given by
1600 / 4300
Step 4: Multiply the fraction obtained by a hundred and modify your answer. 1600 / 4300 ×100
Percentage difference in span length :
= [(difference in span) / span of B] × 100%
= ( 1600 / 4300) ×100
= 37. 2 %
