work out 1/2 x 7 giving your answer as a mixed number
Answer:
[tex]4\frac{1}{2}[/tex]
Step-by-step explanation:
This question is basically saying: what is half of 7, or what is 7 divided by 2?
Based on this, it can be written both of the ways as:
»» [tex]\frac{1}{2}[/tex] of 7 OR 7 ÷ 2
So, just solve using either one and you’ll get 4.5 or [tex]4\frac{1}{2}[/tex]. But since the question wants the answer to be a mixed number, then choose [tex]4\frac{1}{2}[/tex].
Hope this helps! :)
The figures are similar, and the ratio of the perimeters is 2 : 5. Find x.
Answer:
x=3.2
Step-by-step explanation:
8*0.4=3.2
We have that for the Question "The figures are similar, and the ratio of the perimeters is 2 : 5. Find x." it can be said that the perimeters of x is
x=3.2
From the question we are told
The figures are similar, and the ratio of the perimeters is 2 : 5. Find x.
Generally the equation for the the ratio is mathematically given as
2=x
and
5=8
Therefore
[tex]x=\frac{2*8}{5}[/tex]
x=3.2

2. 9m + 2[tex]\sqrt{n}[/tex]
3. 6a
4. (5a - 3b)[tex]\sqrt{5y}[/tex]
Step-by-step explanation:
1. since a and c share the same squareroot x, you can combine these together.
2. First add like terms together. 4m - m + 6m = 9m. Then 5[tex]\sqrt{n}[/tex] and -3[tex]\sqrt{n}[/tex] combined equals 2[tex]\sqrt{n}[/tex]
3. First simplify the square roots. squareroot of 16 is 4. square root of 49 is 7. square root of 81 is 9. They are all multiplied by a in the expression. Thus 4a - 7a + 9a = 6a
4. First simplify the radicals, they are not perfect. square root of 125 is equivalent to sqrt(25 * 5), which sqrt of 25 is 5, but we keep the sqrt of 5. For sqrt of 45, it is the same as sqrt9 * sqrt5. sqrt of 9 is the same as 3 and we keep sqrt 5. Thus we get the below:
5a[tex]\sqrt{5y}[/tex] - 3b[tex]\sqrt{5y}[/tex]
We can combine the two like terms and get the final answer above.

Answer:
Step-by-step explanation:
I don't know what you were supposed to do with 3 but 4 looks much easier.
It's telling you to increase the side lengths by a factor of 3y
4x(3y) + 4x(3y) = 3y * 3y

Perimeter = 24xy + 9y^2

John is buying food for his cat, Fluffy. Fluffy LOVES a fancy wet food which costs $1.50 per day. Fluffy will also tolerate dry food which is $0.75 per day. John wants to spend at most $9.00 on cat food each week
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.
Hence:
x + y = 7 (1)
Also, John wants to spend at most $9.00 on cat food each week. Hence:
1.5x + 0.75y ≤ 9 (2)

A car is traveling at a speed of 72 kilometers per hour. What is the car's speed in kilometers per minute? How many kilometers will the car travel in 2 minutes?
Do not round your answers.
72/60 to get the speed per minute which is 1.2 miles per minute. From there you can just multiply by 2 to get how far the car will travel in two minutes which is 2.4 kilometers. Not rounded btw.

Zachary buys a one pint bottle of juice for $3.20. What is the unit rate of the cost of the juice per fluid ounce?
How many fluid ounces of juice did Zachary buy?
Answer:
Zachary bought 16 ounces of juice
Step-by-step explanation:
First you figure out how many ounces are in a pint ( Which in case your wondering it's 16)
Then you take that number and divide $3.20 by 16 which gives you .20 cents.
You can double check my answer by multiplying .20 by 16 which gives you $3.20.

NP and MQ are medians of triangle NML. Find XQ if MQ=3x-3 and XQ=2x-6. PLEASE HELP
9514 1404 393
Answer:
4
Step-by-step explanation:
We assume that point X is the intersection point of the medians. Then ...
MQ = 3XQ
3x -3 = 3(2x -6)
3x -3 = 6x -18 . . . eliminate parentheses
15 = 3x . . . . . . . . . add 18-3x
5 = x . . . . . . . divide by 3
Now, we can find XQ:
XQ = 2x -6 = 2(5) -6
XQ = 4

Question 3: Jason
receives $40 from
selling 5 adult tickets
and 8 students tickets.
.write an equation to
represent the situation.
Answer:
$40 = 5a + 8s
Step-by-step explanation:
For this question all we need to know is that $40 is equal to 5 prices of the adult tickets plus the 8 prices of the student tickets. From here we can just give a variable to each price and make an equation, like so
Let "a" be the price of the adult ticket and
Let "s" be the price of the adult ticket, then....
$40 = 5a + 8s
(Just to make sure you understand I will repeat. 5 comes from he fact hat there were 5 adult tickets sold which means that there is 5 adult ticket prices in the $40, and exactly the same reasoning goes for the student tickets, 8 students tickets were sold which means the is 8 prices of the student ticket inside the $40.)

Two random samples of 25 people were asked how many 12-ounce cans of soda they consume each week. The first sample contained both males and females, aged 12-19. The second sample contained both males and females, aged 20-39. The results are shown in the table below. Using complete sentences, make one inference comparing the two groups, and explain your reasoning.
Answer:
One inference that can be made is that the age group of 12-19 consume more sodas than the age group of 20-39.
Step-by-step explanation: ok sooooo
The required individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19.
What is mathematical reasoning?Mathematical reasoning is the process of using logical thinking and mathematical concepts to solve problems, prove theorems, and develop mathematical models. It involves identifying patterns, making conjectures, and using deductive reasoning to arrive at logical conclusions based on given assumptions.
Based on the information given in the table, it can be inferred that individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19. This inference can be made because the mean and median values of the second sample (aged 20-39) are higher than those of the first sample (aged 12-19). Specifically, the mean for the second sample is 8.6 cans of soda per week, while the mean for the first sample is 6.96 cans of soda per week. Similarly, the median for the second sample is 8 cans of soda per week, while the median for the first sample is 5 cans of soda per week.
