Given sequence:
0.4, 2, 10, 50, ...The first term is:
a₁ = 0.4The common ratio is:
r = 50/10 = 10/2 = 2/0.4 = 5The formula for the nth term is:
aₙ = a₁rⁿ⁻¹aₙ = 0.4*5ⁿ⁻¹Jamie took 7 maths tests and got a score of 68,71,71,84,53,62 and 67 .What was Jamie's mode score?
What value of x makes 1/2(3x+4)=1/2x true. A.2. B.1. C-1. D.-2
PLZZ HURRY
Answer:
The answer is D, -2. brainliest pls! :D
Step-by-step explanation:
-2*3=-6
-6+4=-2
-2*1/2=-1
-1=1/2x
1/2*-2=-1
-1=-1
The value of x such that it will make the given expression (1/2)(3x+4)=(1/2)x true is x = - 2 therefore, option (D) will be correct.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
As per the given expression,
(1/2)(3x+4)=(1/2)x
(3/2)x + 4/2 = x/2
3x/2 + 2 = x/2
3x/2 - x/2 = -2
(3x - x)/2 = -2
2x = -4
x = -2
Hence "The value of x such that it will make the given expression (1/2)(3x+4)=(1/2)x true".

What is the area of this figure?
Answer:
58.5
Step-by-step explanation:
Split the figure into three shapes; square, trinagle, and rectangle.
Square is 3 ⋅ 3 = 9
Triangle's sides are 3 and 11 so...
(3 ⋅ 11)/2 = 16.5
Rectangle is 3 ⋅ 11 = 33
Once you have the area of all the figures, you just add them together so...
9 +16.5 + 33 = 58.5
Answer:
area of the figure= 58.3ft²
Step-by-step explanation:
area of the figure= area of trapezoid+ area of a rectangle
area of the figure= [½(a+b)*height]+ (length*breadth)
area of the figure= [½(3+14)*3]+ (11*3)
area of the figure=25.3+ 33
area of the figure= 58.3ft²

You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1
the vertical change is -1 horizontal change is 3 so by rise/run=-1/3
-1/3 is the slope
for the second problem this is confusing but just read and try to analyze
vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)
The y intercept is the point where the line hits the y axis, so at point (0, 5)
The function is y=mx+b
m is the slope
b is the y intercept
so y=-1/3x+5

25y^2-60y+36
Answer:
(5y-6)^2
Step-by-step explanation:
Note that the polynomial 25y^ 2 −60y+36 is a perfect square trinomial, so we will use the following formula.
A ^2 −2AB+B^2 =(A−B) ^2
In this example we have A=5y and B=6 so,
25y^2 −60y+36=(5y−6)^2

Anita, Byron, Carlos, and Dominique buy a gift for their grandmother. They split the cost equally and each pay $14.62. Which equation represents d, the cost of the gift in dollars?
14.62 = d minus 4
14.62 = d divided by 4
14.62 minus 4 = d
14.62 divided by 4 = d
Answer:
14.62= d divided by 4

Triangle ABC above has side a = 1 and side c = 2. What constraints does the triangle inequality theorem put on side b?
Answer:
[tex]3 > b[/tex]
Step-by-step explanation:
Given
[tex]a = 1[/tex]
[tex]c = 2[/tex]
Required
Inequality to measure the length of b
The triangle inequality theorem states that:
[tex]a + b > c[/tex]
[tex]a + c > b[/tex]
[tex]b + c > a[/tex]
On side b, we make use of:
[tex]a + c > b[/tex]
Substitute values for a ad c
[tex]1 + 2 > b[/tex]
[tex]3 > b[/tex]
The inequality is: [tex]3 > b[/tex]
