What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
Given
Madeline has to earn at least 80 points for her science fair project. So far on the rubric she has 64 points.
so,
Total = 80 (at least)
accumulated = 64
Required
Express as an inequality
In inequalities, at least means ≥
So, the expression is:
Where x represents the additional points
x + 64 ≥ 80
Solve for x
x ≥ 16
Hence, she needs at least 16 points.

A total of 715 tickets were sold for the school play. They were either adult tickets or student tickets. There were 65 more student tickets sold than adult tickets.
Answer:
There were 423 adult tickets sold.
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 65 = the number of student tickets sold
x + x + 65 = 715
2x = 715
x = 357.5
x + 65 = 422.5 (round up)
Answer:
adults=325& students=390
Step-by-step explanation:
let me the tickets for adults be x
for students will be x+65
x+x+65=715
2x+65=715
2x=715-65
2x=650
x=650÷2
x=325

Answer:
a = 29
b = 20
Step-by-step explanation:
2a - 1 = 57
+ 1 + 1
2a = 58
/ 2 / 2
a = 29
2a - 1 + 7b - 17 = 180
2 (29) - 1 + 7b - 17 = 180
58 - 1 + 7b - 17 = 180
57 + 7b - 17 = 180
7b + 40 = 180
- 40 - 40
7b = 140
/ 7 / 7
b = 20

Step-by-step explanation:
A gas station sells unleades regular petrol and preminum charged by station for regular is$1.299
Answer:
a. Assuming gallons of unleaded regular is denoted by r; and unleaded premium by p.
Revenue from one gallon of unleaded regular is $1.299 and from unleaded premium is $1.379.
Revenue function = 1.299r + 1.379p
b. Cost of one gallon of unleaded regular is $1.219 and for unleaded premium is $1.289.
Cost function = 1.219r + 1.289p
c. Total profit = Revenue - Cost
= 1.299r + 1.379p - 1.219r - 1.289p
= 1.299r - 1.219r + 1.379p - 1.289p
= 0.08p + 0.09p
d. If station sells 100,000 gallons of unleaded regular and 40,000 of unleaded premium;
= (0.08 * 100,000) + (0.09 * 40,000)
= 8,000 + 3,600
= $11,600

Marco scored 20 points at the basketball game . If this is 40% of the total score, what was the total score for the basketball game ?
The total score for the basketball game was 50 points.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
Points scored by Marco in basketball game = 20
Also, points scored by Marco is 40% of the total score,
Implies that,
40% = 20
1 % = 20 / 40
To determine total score, find value of 100%,
100 % = (20 / 40) x 100
= 50
The total score for the basketball game was 50.

What is the sum of first k+1 even numbers
Answer:
[tex]Sum = (k+1)(k+2)[/tex]
Step-by-step explanation:
Given
k + 1 even numbers
Required
Their sum
This question will be solved using the sum of nth term of an AP
[tex]S_n = \frac{n}{2}(2a + (n - 1)d)[/tex]
Where
a = the first even number
[tex]a = 2[/tex]
n = number of terms
[tex]n =k +1[/tex]
d = difference between consecutive even numbers
[tex]d = 2[/tex]
So, the expression becomes:
[tex]Sum = \frac{k+1}{2}(2 * 2 + (k + 1 - 1) * 2)[/tex]
[tex]Sum = \frac{k+1}{2}(2 * 2 + (k) * 2)[/tex]
[tex]Sum = \frac{k+1}{2}(4 + 2k)[/tex]
[tex]Sum = \frac{(k+1)(4 + 2k)}{2}[/tex]
Factorize 4 + 2k
[tex]Sum = \frac{(k+1)*2*(2 + k)}{2}[/tex]
[tex]Sum = (k+1)*(2 + k)[/tex]
[tex]Sum = (k+1)*(k+2)[/tex]
[tex]Sum = (k+1)(k+2)[/tex]

A consumer advocate group selects a random sample of 205 snow foods in find 174 of them contain more what is indicated on the snacks nutritional information. Create a 90% confidence interval for the population proportion for a snack foods that contain more fat grams and was indicated on the snacks nutritional information
Answer: (0.809, 0.891)
Step-by-step explanation:
Let p = population proportion for a snack foods that contain more fat grams and was indicated on the snacks nutritional information .
As per given , we have
Sample size : n= 205
Sample proportion: [tex]\hat{p}=\dfrac{174}{205}\approx0.85[/tex]
z-value for 90% confidence = 1.645
Confidence interval for p: [tex]\hat{p}\pm z^* \sqrt{\dfrac{p(1-p)}{n}}[/tex]
[tex]0.85\pm (1.645)\sqrt{\dfrac{(0.85)(1-0.85)}{205}}\\\\=0.85\pm (1.645)\sqrt{\dfrac{0.85\times0.15}{205}}\\\\= 0.85\pm (1.645)\sqrt{0.000621951219512}\\\\=0.85\pm0.041\\\\=(0.85-0.041,\ 0.85+0.041)\\\\= (0.809,\ 0.891)[/tex]
Hence, the required confidence interval = (0.809, 0.891)
The perimeter of a rectangle is 52 feet. The length is 2 more than twice the width. What is the length of the rectangle?
Answer: The Length of the rectangle is 18 feet.
The width is 8 feet
Step-by-step explanation: Perimeter is 2w + 2L
Length here is 2w + 2 Substitute this value for L in the equation.
P = 2w + 2L
52 = 2w + 2(2w + 2) distribute and add
52 = 2w + 4w + 4
52 = 6w + 4 Subtract 4 from both sides, Then divide both sides by 6 to solve for w
48 = 6w
8 = w The width is 8 ft
Substitute into the original expression for Length
Length here is 2w + 2 : 2(8) + 2 16 + 2 = 18
The Length is 18 feet.
Check: in the original equation P = 2w + 2L
52 = 2(8) + 2(18)
52 = 16 + 36 TRUE!
Answer:
The length would be 18ft the width would be 8ft
