The first time Lori played a game, she scored 100 points. She doubled her previous score each of the next 3 times she played the game. What was Lori's scored the first 4 times she played the game
Answer:
1500 points
Step-by-step explanation:
Given
[tex]Initial\ Score = 100[/tex]
[tex]Rate = 2[/tex]
Required
Determine the total score in first 4 games
This question illustrates a geometry progression and will be solved as follows:
[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]
Where
[tex]a = First\ Term = 100[/tex]
[tex]r = common\ ratio = 2[/tex]
[tex]n = 4[/tex]
[tex]S_4 = \frac{100(2^4 - 1)}{2 - 1}[/tex]
[tex]S_4 = \frac{100(16 - 1)}{1}[/tex]
[tex]S_4 = \frac{100(15)}{1}[/tex]
[tex]S_4 = 1500[/tex]
Hence, the score in first four games total 1500 points

Answer:
5x - 4 = 11
1/2x + 15 = 9
Step-by-step explanation:
I dont exactly know how u would show work.
If it says something is less than a number, then it will be at the back of the equation. So skip that part and u will see it says five times a number. The number is unknown therefore it will a variable (i chose x to be the variable). 5 times x is 5x. Minus the 4 would be 5x - 4. Then it says the equation equals 11. So 5x - 4 = 11.
If it says something is more than a number, it can be on either side of the equation using the commutative property of addition. But if we want to consider it being like subtraction, then it also will be in the back of the equation. A half is one over two (1/2). A half of x is 1/2x. Plus the 15 would be 1/2x + 15. It then states that the equation equals 9. So 1/2x + 15 = 9.

Given that these triangles are similar, which side corresponds to side GE?
Given that these triangles are similar, which side corresponds to side JK?
I NEED HELP ASAP
Answer:
1.KL
2.FG
Step-by-step explanation:
I hoped I helped
The side corresponds to side GE is Kl and the side corresponds to side JK is GF
What is similarity?Similarity is a term used for similar figures, in similar figures, we have equal corresponding angles and corresponding sides in equal ratios.
Given that, the two triangles are similar, since the figure of triangles is not given, we will consider the triangles attached to the solution,
We know that, the similar triangles are having corresponding sides are in equal ratios,
The triangles are Δ GEF ~ Δ KLJ
So, the corresponding sides are :
GE ~ KL
EF ~ LJ
GF ~ JK
Hence, the side corresponds to side GE is Kl and the side corresponds to side JK is GF

What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ (t - 8) - (t + 15)
Now,
Subtract the expression as;
⇒ (t - 8) - (t + 15)

Answer:
A. 1/3
Step-by-step explanation:
Dado que:
una manzana se corta en 12 partes y se comen ocho partes.
La fracción de manzanas consumidas = 8/12
= 2/3
La fracción de manzanas que quedan = valor original de la manzana que se corta - la fracción de la manzana que se come
La fracción de manzanas que quedan [tex]=1- \dfrac{8}{12}[/tex]
La fracción de manzanas que quedan [tex]=\dfrac{12-8}{12}[/tex]

Dr. Mann mixed 9.357 g of chemical A, 12.082 g of chemical B, and 7.502 g of chemical C to make 5 doses of medicine. About how much medicine did he make in grams? Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum. Show all your thinking.
Answer:
Step-by-step explanation:
.
1) About how much medicine did he make in grams?
Dr. Mann mixed
9.357 g of chemical A,
12.082 g of chemical B,
7.502 g of chemical C
We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)
=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)
= 28.941 grams in total
The next step is to round up those chemicals value to their nearest tenth as asked by question
Dr. Mann mixed
9.357 g of chemical A= 9.4grams
12.082 g of chemical B,=12.1grams
7.502 g of chemical C =7.5grams
2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.
Then the sum after rounding up to nearest tenth is
(9.4grams +12.1grams + 7.5grams)
=29 gram

Which number sentence is not true?
OA) |-20| < 20
OB) |9| = 9
OC) |-20| > |9|
OD) |9|< 20
Answer:
Option A is correct option
Step-by-step explanation:
We need to find which number sentence is not true.
We will check each option.
Option A
|-20| < 20
We know that |-a|=a
20 < 20 (false)
So, this number sentence is not true.
Option B
|9| = 9
We know that |a|=a
9=9 (true)
So, this number sentence is true.
Option C
|-20|>|9|
We know that |-a|=a
20>9 (true)
So, this number sentence is true.
Option D
|9| < 20
We know that |a|=a
9<20
So, this number sentence is true.
So, Option A is correct option

The larger of two numbers is four times the smaller number, and their difference is 18. Find the two numbers.
Answer:
x = 12 , y = 10
Step-by-step explanation:
Let x , y are two numbers.
x > y
1 ) Three times the greater is 18 times their
difference
3x = 18( x - y )
x = 6( x - y )
x = 6x - 6y
6y = 5x
y = 5x/6 ——-( 1 )
2 ) 4 times the smaller is 4 less than twice
the sum of the two
4y + 4 = 2 ( x + y )
2y + 2 = x + y
y = x -2 ——( 2 )
From ( 1 ) and ( 2 ) ,
5x/6 = x -2
( 5x /6 ) - x = -2
( 5x - 6x ) /6 = -2
-x = -12
x = 12
Put x = 12 in equation ( 2 ) , we get
y = 12 - 2
y = 10
Therefore ,
x = 12 , y = 10

Answer: 7.3 pounds of coarse sand.
Step-by-step explanation:
Rearrange x = 7y - 5 to make y the subject.
By rearranging x = 7y - 5 to make y the subject, we get
x + 5 = 7y ( By transposition method )
or, [tex] \huge \purple {\tt {\frac{x + 5}{7} = y}} [/tex]
Answer:[tex] \huge \pink {\tt {y = \frac{x + 5}{7}}} [/tex]
The equation x = 7y - 5 can be rearranged as y = x/7 + 1/7 after making the subject as y.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
x = 7y - 5
To make the subject as y:
x + 5 = 7y
Or
7y = x + 5
y = 1/7[x + 5]
y = x/7 + 1/7
Thus, the equation x = 7y - 5 can be rearranged as y = x/7 + 1/7 after making the subject as y.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. -16x^2+129x+119
Answer:
8.90 seconds
Step-by-step explanation:
When the rocket hits the ground, its height ( y ) will be zero. This means we can write the equation as:
0 = -16x²+129x+119So we need to solve that equation:
a = -16b = 129c = 119x = [tex]\frac{-b\frac{+}{-}\sqrt{b^2-4ac} }{2a}[/tex]x₁ = -0.84
x₂ = 8.90
We discard x₁, as it is negative.
So the answer is x₂, 8.90 seconds.

I WILL MARK BRAINLIEST! I NEED HELP ASAP! Solve for x, y, and a.
Answer:
a = 14, x = 55, y = 60
Step-by-step explanation:
a: Find the number that is between 10 and 18, 10 + 18 = 28 divide by 2 = 14, so a = 14
x: Due to corresponding angles theorem, so x = 55 degrees
y: Straight line is 180 degrees, and as we can see at the left side of the image there's a straight line where only 55 degrees was identified so 180 - 55 = 125 and since x = 55 degrees due to corresponding angles, the angle above y is 120 also due to corresponding angles. A quadrilateral is 360 degrees, so:
125 + 55 + 120 + y = 360
180 + 120 + y = 360
300 + y = 360
y = 60
8x - 3(x - 1) = 2x + 6 solve for x and show work
Answer:
x= 1
Step-by-step explanation:
open brackets first
8x - 3x + 3 = 2x + 6
Calculate
5x+3= 2x+6
transpose the like terms
5x-2x= 6-3
calculate
3x= 3
x= 3/3
x= 1
Answer:
x = 3
Step-by-step explanation:
8x - 3(x - 1) = 2x + 6
simplify
8x - 3x + 3 = 2x + 6
add like terms
5x + 3 = 2x + 6
subtract 2x from both sides
3x + 3 = 6
subtract 3 from both sides
3x = 3
divide by 3
x = 3
