6x^2+18x+12 is the right answer.You and a friend make a total of 63 bird houses. The ratio of bird houses you make to bird house your friend makes is 4 : 5 How many bird houses did your friend make?
Answer:
Your friend made 35 bird houses.
Step-by-step explanation:
If the ratio from your houses to your friends houses is 4:5, that means that for every 9 houses built, your friend did 5. So, every 18 houses built, your friend did 10. For every 27, your friend did 15, and for 36, your friend did 20, and for every 45, your friend did 25, and for every 54, your friend did 30, and for every 63, your friend did 35.

what is the 93rd term of the arithmetic sequence -6, 13, 23 and how do I find it?
Answer:
Step-by-step explanation:
the formula for an arithmetic sequence is
a, a+d,a+3d,a+3d etc, where d is the common difference
we have the terms -6, 13,23
first term is -6
-6+19=13
however, 13+10=23
this is not an arithmetic sequence

To find the precent of something you multiply it by 1/100th of what precentage youre trying to find. That's a really weird way of explaining it... It's easier to show with examples.
Some numbers you probably know off the top of your head (whats 100% of 5 or 50% of 20?) But you can also move the decimal place over twice. 100 becomes 1.00 and 1x5 is 5. Same with 50%, it turns into 0.50 or 0.5. and 0.5x20 is 10...
0.25 x 80 is 20 so 25% of 80 is 20
0.8 x 125 is 100 so 80% of 125 is 100
0.6 x 120 is 72 so 60% of 120 is 72
0.45 x 15 is 6.75 so 45% of 15 is 6.75
0.5 times 60 is 30 so 50% of 60 is 30
and for the shopkeeper
0.46 x 150 is 69 so he sold 69 newspapers (nice)
0.24 x 150 is 36 so he sold 36 pens
0.12 x 150 is 18 so he sold 18 books
and 0.18 x 150 is 27 so he sold 27 "other items"
we can check this by adding together the items sold
69+36+18+27=150
(this only works if they gave us 100% of the items sold)
Find the slope, or rate of change, from the graph.
Answer:
-1/2
Step-by-step explanation:
slope is rise over run
or y change divided by x change
to find the slope you need to find points on the graph that meet exact points on the graph
i see (0,1) and (2,0)
to find slope without graph it would be (y2-y1)/(x2-x1)
in this case (0-1)/(2-0)
=-1/2
with graph you can count that it goes down -1 squares and to the right 2 squares

some soiled goods are sold for 2 /5 of their original price. what will be the selling price of a pair of trouser originally Costing#850.00
Answer:
$340.
Step-by-step explanation:
Given that some products, such as a pair of trousers in this case, are sold at 2/5 of their value, if the trousers cost $ 850, the following calculation must be performed to determine their sale value:
2/5 = 0.4
850 x 0.4 = X
340 = X
Therefore, selling them at 40% of their value, the trousers' sale value was $ 340.

(Photo) Which table shows a relation that is not a function?
Applying the function concept, it is found that the top right relation is not a function.
For a relation to be classified as a function, each value of the input may be related to only one value of the output.In the top right relation, the input of x = -3 is related to two values of the output, y = 4 and y = -2, which is why it does not represent a function.

There are a total of 64 students in a filmmaking club and a yearbook club. The filmmaking club has 14 more students than the yearbook club. a. Write a system of linear equations that represents this situation. Let x represent the number of students in the filmmaking club and y represent the number of students in the yearbook club.
Answer:
x + y = 64
x = y + 14
Step-by-step explanation:
Given:
Total number of student = 64
x = number of students in filmmaking club
y = number of students in yearbook club.
Computation:
So,
x + y = 64
And,
x = y + 14
So
Number of students in yearbook club = 25
Number of students in filmmaking club = 39
The system of linear equations is x + y = 64 and x = y + 14.
Given that,
The total number of students is 64 .Here we assume the x be the number of students in filmmaking club .And, y be the number of students in yearbook club.Based on the above information, the calculation is as follows:
x + y = 64
And,
x = y + 14
Therefore,
We can say that
Number of students in yearbook club = 25
And, the number of students in filmmaking club = 39

Reconcile pedro's check register.
Answer:
$399.80
Step-by-step explanation:
earned interest means he should have $4.36 more.
Charge means $5.50 less.
Withdrawal means $150 less.
Therefore his balance should be 550.94+4.36-5.50-150 = $399.80
The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2. The combined area of these three rooms is 189 square feet. What is the area of each room? (Ex. Kitchen Area=______, Playroom Area=______, Dining Room=_____) *
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.
Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet
Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet
Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet

Which is the better buy: 4 cans of peaches for $6.44 or 3 cans for $4.71?
Answer:
3 cans for $4.71
Step-by-step explanation:
6.44/4= $1.61
4.71/3= $1.57
3 cans for $4.71 is the better buy
Answer:
4 cans is the better option because $6.44 divided by 4 is 1.61. And if you add $4.71 + $1.61 + $1.61 it would equal $7.43
