Answer:
To multiply using fraction form, we can convert the decimal numbers to fractions and then multiply them together.
4.4 can be written as 44/10
3.2 can be written as 32/10
So the multiplication would be:
(44/10) * (32/10) = (4432)/(1010) = 1408/100
To simplify this fraction, we can divide the numerator and denominator by their greatest common factor which is 4, we get:
1408/100 = 352/25
So the product of 4.4 and 3.2 is 352/25 in fraction form.
Mick's zoo offers a promotional deal: get a free $3 cotton candy and a free $2 soda with the purchase of five $12 admission tickets. A group of 20 students will each purchase a ticket. If half of them want cotton candy and ¼ of them want soda, how many dollars would they save by using the promotional deal?
(please answer and explain!!!!!!)
By using the promotional deal the kids saved 20 dollars.
What is a promotional deal?Simply put, a promotion is a discounted product or service that you already have available on your website or that you want to offer. We re-promote it, and the consumer can view it and be directed to the Merchant's website, location, or phone number – no online transaction is necessary.
A promotion is frequently a recurring event that happens weekly or daily to draw more people to a particular day. It doesn't necessitate an online transaction but does include some sort of discount or added value. A promotion may be accessible online for several days, weeks, months, or even years.
When you buy 5 $12 admission tickets you get a free $3 cotton candy and a free $2 soda
A group of 20 buys each $12 admission tickets, i.e
20/5
= 4 promotional deal
All together they are eligible for 4 promotion deal.
They get 4 $3 cotton candy and 4 $2 soda
= $12 + $8
= $20
Half of them want cotton candy = 20/2
= 10
¼ of them want soda = 20/4
= 5
10 × $3 cotton candy
= $30
5 × $2 soda
= $10
Total $40
Dollars the save = $40 - $20
= $20
Thus, By using the promotional deal the kids saved 20 dollars.

The first option 3² × 5 × 7 is the correct option to show the prime factorization of 315 in exponential notation.
What is prime factorizationPrime factorization is a way of expressing a number as a product of its prime factors. A prime number is a number that has exactly two factors, which includes 1 and the the number.
The 1st five prime numbers includes: 2, 3, 5, and 7. We shall divide the number 315 with prime numbers that are factors beginning with 3;
315/3 = 105
105/3 = 35
3 is not a factor of 35, the next prime number 5 is, so;

Solve the system. Estimate the solution first. Enter whole numbers for the estimated solution and improper fractions in simplest form for the algebraic solution.
6x + y = 2
x - 4y = 2
The estimated solution is ( , ).
The algebraic solution is ( , ).
The solution of the system of equation is as follows:
x = 2 / 5 and y = - 2 / 5.
How to solve system of equation?System of equation can be solved using different method such as elimination method and substitution method.
Let's solve the system of equation by substitution method.
6x + y = 2
x - 4y = 2
Hence,
x = 2 + 4y
substitute the value of x in equation(i)
6(2 + 4y) + y = 2
12 + 24y + y = 2
12 + 25y = 2
25y = 2 - 12
25y = - 10
y = -10 / 25
y = - 2 / 5
Hence, let's find the value of x
6x = 2 - y
6x = 2 + 2 / 5
6x = 10 + 2/ 5
6x = 12 / 5
x = 12 / 5 × 1 /6
x = 12 / 30
x = 2 / 5

What is similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"
Given that,
One triangle, ΔBCF

The definition of a rate of change is a rate that expresses how one quantity changes in relation to another quantity. When d(t)=2t is stated, the average speed from t=5 to t=9 is 28 feet or 2 feet per second.
What is the Rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
d(t)=2t² is given, we need to find the average speed in feet per second from t=5 to t=9.
d(t)=2t².
The average rate of change is calculated by the formula:
d(t₂) - d(t₁) / t₂ - t₁
So plug in 5 as t₁ and 9 as t₂.
=> d(9) - d(5) / 9 - 5
=> (2×81) - (2×25) / 9 - 5
=> 162 - 50 / 4
