Arnav is selling boxes of cookies.
He sells each box for $3.75.
His goal is to make more than $30.
How many boxes of cookies could he sell to reach his
goal?
Answers
Arnav needs to sell more than 8 boxes of cookies to reach his goal of making more than $30. Since the number of boxes must be a whole number, Arnav would need to sell at least 9 boxes of cookies to achieve his goal.
To determine how many boxes of cookies Arnav needs to sell to reach his goal of making more than $30, we can set up an inequality based on the selling price of each box.
Let's represent the number of boxes he sells as "x". Since each box is sold for $3.75, the total amount of money he will earn from selling "x" boxes is 3.75x.
To reach his goal of making more than $30, we can write the following inequality:
3.75x > 30
To solve for "x", we divide both sides of the inequality by 3.75:
x > 30 / 3.75
Simplifying the right side of the inequality, we get:
x > 8
To fulfil his objective of earning more than $30, Arnav must sell more than 8 boxes of cookies. Arnav would need to sell at least 9 boxes of cookies in order to reach his objective because the number of boxes must be a whole number.

Whose kite is flying higher in the sky
Answers
Answer:
Kattie's kite is flying higherStep-by-step explanation:
Let the height of each kite be h.
The h is opposite to angle of elevation and the sting length is hypotenuse of the formed triangle.
Kattie's kite:
h/864 = sin 38°h = 864 sin 38°h = 532 ft (rounded)Matt's kite:
h/725 = sin 40°h = 725 sin 40°h = 466 ft (rounded)Kattie's kite is flying higher as 532 ft > 466 ft

Mrs. Foust wants to know Aziza’s age. She knows that Aziza is the middle child. Her sister, Capri, is 4 years older than Aziza, and her sister, Portia, is 5 years younger than Aziza. The sum of their ages is 38. Let a represent Aziza’s age. Which statements are true about this scenario? Check all that apply.
Answers
Answer:
The expression that represents Capri’s age is a + 4.
The expression that represents Portia’s age is a – 5.
Step-by-step explanation:
The expression that represents Capri's age is a + 4.
The expression that represents Portia's age is a -5.
To write an equation for this scenario, Capri's age needs to be equal to Portia’s age
The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.
Solving this equation will give Aziza's age.
Aziza'a age = a
Portia age = a - 5
Capri's age = 4 + a
a + a - 5 + 4 + a = 38

Step-by-step explanation:
From the given choices, we areto select the one that are squares of linear expressions
1) For the expression (12x+4)²
This is regarded as the square of 12x+4 since the expression 12x4 is enclosed in parenthesis
2) For the expression p^2−6p+9
Factorize;
p^2−6p+9
p^2−3p-3p+9
p(p-3)-3(p-3)
(p-3)(p-3)
(p-3)²
Hence p^2−6p+9 is a square of the expression p-3

Isabella opened a savings account and deposited $25,000.00. The account earns 20% interest, compounded annually. If she wants to use the money to buy a new car in 2 years, how much will she be able to spend on the car?
Answers
Answer:
$11,000
Step-by-step explanation:
1st year the account earned 20% from $25,000 = $5,000 | total = $30,000
2nd year the account earned 20% from $30,000 = $6,000
by adding the earnings of 2 years, she will be able to spend $5,000 + $6,000 = $11,000
