Step-by-step explanation:
Y = 3x - 10
So, 4x + 5y = 7
= 4x + 5(3x - 10) = 7
= 4x + 15x - 50 = 7
= 19x - 50 = 7
= 19x = 7 +50
= 19x = 57
= X = 57/19
X = 3

The width of the popcorn box that Mayerlin models given its dimensions and the volume is 3.2 inches.
What is the width?A rectangular prism is a three-dimensional shape that is made up of six faces and 12 sides.
Volume = length x width x height
Width = volume / (length x height)
49 / (2 3/4 x 5 1/2) = 3.2 inches

Since the variable x is the numerator of the fraction, we first need to multiply each side by 6, since the denominator is 6. After doing this, the equation should now look like this: [tex]18 = x + 31[/tex]. Next, we subtract 31 from 18 following the rule. 18 - 31 = -13. x is equal to -13.
For shown work in order:
[tex](6) 3 = x +31[/tex]
[tex]18 = x + 31[/tex]
[tex]18 - 31 = x[/tex]

Answer:
1) (Un) is a geometric sequence.
2) Un+1 - Un ≤ 0.
3) (Un) is decreasing.
4) (Un) is convergent.
5) sum = 155
Step-by-step explanation:
Un+1 = 0.5Un
U₀ = 80
1) U is a geometric sequence (reason : Un+1 = 0.5Un).
2) Un+1 - Un = 0.5Un - Un = Un×(0.5 - 1) = -0.5Un ≤ 0 (because Un ≥ 0).
Remark: use Mathematical induction to prove that Un ≥ 0
3) Un+1 - Un ≤ 0
then
Un+1 ≤ Un
then
the sequence U is decreasing.
4) U is decreasing and Un ≥ 0
Then U is convergent.
5) Since U is geometric sequence with first term U0 = 80 and common ratio = 0.5 .
Important: review the sum of consecutive terms of a geometric sequence.
Then
[tex]U_0+ U_1+ U_2+ U_3+ U_4=U_{0}\times \frac{1-\left( 0.5\right)^{5} }{1-0.5}=160\times(1-\left( 0.5\right)^{5} )=155[/tex]

A survey was given to 90 high school students. They were asked if they preferred fiction or non-fiction and if they preferred indoor or outdoor activities. Partial survey results are shown in the table.
What percent of students in the survey, to the nearest whole number, prefer outdoor activities given they prefer non-fiction?
Enter a number in the box.
P(outdoor | non−fiction)= _%
Answer:
11% of people preferred outside and non-fiction
Step-by-step explanation:
Table attached,
10/90 = 0.11
0.11 = 11%
The percent of students in the survey that prefer outdoor activities given they prefer non-fiction is 11%.
What is the percent?The first step is to determine the total number of people that like fiction: 24 + 30 = 54
Now, determine the total number of people that like non-fiction: 90 - 54 = 36
The third step is to determine the total number of people that like indoor activities and non-fiction: 50 - 24 = 26
The fourth step is to determine the total number of people that like outdoor activities given they prefer non-fiction: 36 - 26 = 10
Percentage of people that prefer outdoor activities given they prefer non-fiction = (10 / 90) x 100 = 11%
