Step-by-step explanation:
20 - 12 = 8 so he spent 8$ in 4 days.
8 ÷ 4 = 2, so he spent 2$ each day
The rate of Jaman spending money every day will be $2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Jamal's parents give him $20 to spend at camp. Jamal spends the same amount of money on snacks each day. After 4 days he has $12 left .
The rate of spending money every day will be calculated as,
Spending in 4 days, 20 - 12 =$8
Rate of spending = 8 ÷ 4 = $2
Therefore, the rate of Jaman spending money every day will be $2.

Diego props a 10ft ladder against the wall how high up will the ladder reach if the foot of ladder is 5 feet away from the wall ?
Answer:
5√3 ft
Step-by-step explanation:
If the ladder is 10ft tall, then that represents the hypotenuse. If the foot of our ladder is 5ft away from the wall, that is a side length that we know. Using the Pythagorean Theorem, a²+b²=c², where a and b are side lengths of a right triangle, and c is the hypotenuse, we can solve for the missing side length:
a²+b²=c²
(5)²+b²=(10)²
25+b²=100
b²=75
b=√75
b=5√3
So the ladder will reach a height of 5√3 ft.

A city has a population of 310,000 people.Suppose that each year the population grows by 6.5% . What will the population be after 9 years?
Answer:
546,397 people
Step-by-step explanation:
We solve for the above question, using the formula for Exponential growth
The formula is given as
P(t) = Po (1 + r)^t
Po = Initial population = 310,000
r = Exponential growth rate = 6.5% = 0.065
t = Time in years = 9
P(t) = Population size after time t
Hence:
P(t) = 310,000 × (1 + 0.065)⁹
P(t) = 546,396.82088 people
Approximately =546,397 people
The population will be 546,397 people after 9 years.
Mayne is 28 years old. She is 12 years older than 2/3 of Laurels age. Which equation can be used to find Laurels age, a?
Answer:
B. ⅔a + 12 = 28
Step-by-step explanation:
Here are the options to this question
) ⅔ + 12a = 28
b) ⅔a + 12 = 28
c) ⅔a + 12a = 28
d) -⅔a + 12 = 28
Mayne's age can be represented with this equation =
28 = 12 + 2/3a
where a = laurels age
