7) Staples charges $28 for 8 boxes of pencils and $47 for 4 pencil sharpeners. Ms. Felix orders 70 boxes of pencils and 21 pencil sharpeners from Staples. How much does Ms. Felix spend on her order?
Answer:
Ms. Felix would spend $491.75 on her order.
Step-by-step explanation:
First, let's identify the components of this word problem that we'll need to solve it. We know that Staples charges $28 for 8 boxes of pencils, and $47 for 4 pencil sharpeners. Before we do anything else, we'll find the unit price of the pencils and pencil sharpeners to make it easier for us. Let's begin with the boxes of pencils. 28 ÷ 8 = $3.50 per box of pencils. As for the pencil sharpeners, 47 ÷ 4 = $11.75 per sharpener. Now that we know the basic costs, let's use them to solve our problem at hand. We'll multiply the number of items ordered by the base cost of the item.
Boxes Of Pencils:
70 × $3.50= $245.00
Sharpeners:
21 × $11.75= $246.75
Now that we know the cost of the two seperate items Ms. Felix ordered, let's add them to get our final answer.
$245 + $246.75 = $491.75Our final answer would be $491.75.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas. 12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
The wheel moves 56 ft in 8 rotations.
Now, in 1 minute the wheel travel
= 56/8
= 7
Now, in 20 rotation the wheel travels
=20 x 7
= 140 feet
Hence, 140 feet travel in 20 rotations.

Help me pls because my teacher says I must finish it
Answer:
for the first equation you will place a point at (0, 3)
you will then go "up 1 and over 1" and place another point (this is your slope) continue doing this until you have formed a line. you may also go "left 1 down 1" to go the opposite direction, creating a negative slope & straight line.
for the second equation you will place a point at (0, -3)
you will then go "up 1 and over 2" and place another point. repeat this a few times. then you will go to (0, -3) and go "left 1 down 2" and create the negative slope effect. this will give you a straight line.

2 specialty pizzas for $38.50 = $_______________ p
Answer:
Step-by-step explanation:
to find this all you need to do is divide the total price by the number of units you have. in this case 38.50 / 2 = 19.25 per pizza
Hello there! :)
If 2 pizzas cost 38.50 dollars, then we have to dibvide by 2 to find out the price of one pizza.
$19.25

Factor the trinomial, or state that the trinomial is prime,
y2 - 5y + 6
Answer:
Im doing this for the points lol
Sorry
Answer:
factorise it
Step-by-step explanation:
in the method ax2 + bx + c
so it can be done just in y
find a common factor
well there isn't one but we can see that we need to factorise it
+1 y2 times 6= 6
because there is only 1 y and you times it by 6
you'll see why when we factorise this
so x the squared number (1) x 6 =6
and the middle number is 5
find two numbers that
x multiply to make six
and add+ to make -5
those numbers are
-3
-2
because -2 + -3 = -5 and -2 x -3 = positive 6
so our answer of y2 + 5y + 6
is identical to = y2 -3y -2y +6
factorise in half
y2 -3y -2y +6
so now we can factorise!
in this bracket we have
a common factor of y in this bracket we have common
factor of 2
= y (y -3) + = -2(y-3)
BUT THERE IS STILL ONE MORE
THEN WE CAN SEE A COMMON FACTOR OF Y-3
put the (y-3) in front and the (-y-2) is left
put y from first bracket and -2 from second bracket into a seperate bracket
yay! factorised
BUT THERE IS STILL ONE MORE
ANSWER = (Y-2) (Y-3)
you can use the rainbow multiplying out of bracket method to prove it works.
PLZ GIVE BRAINLIEST
how it would be written out:
y2 + 5y + 6
y2 -3y -2y +6
y2 -3y -2y +6
y (y -3) -2(y-3)
(Y-2) (Y-3)
two people describe a regular polygon. Brianna says that the polygon has side length 6.3cm and a perimeter 31.5cm. Desiderio says the polygon has side length n and perimeter 5n. which person's description tells you how many sides the polygon has without doing any calculations? why?
9514 1404 393
Answer:
Desiderio
Step-by-step explanation:
The number of sides of a regular polygon is multiplied by the length of the side to get the perimeter. To find the number of sides, the perimeter must be divided by the number of sides.
Brianna's description requires that division look like ...
31.5/6.3 = 5
Desiderio's description requires that division look like ...
5n/n = 5
Since we're supposed to tell the number of sides without doing any calculation, it seems Desiderio's description is better. (We have to realize that n/n = 1, so the factors of n cancel.)
Some of us are familiar with multiplication tables and quickly realize 30/6 = 5 based on memory. Which realization is faster depends on your memory and experience. Most would say evaluating Brianna's description cannot be done without calculation.

Answer:
B
Step-by-step explanation:
to compare the rate of change we must fine the slope:
A. Slope= -9
B. Slope= 3/2
C. Slope= -5
what the answer to this equation?
9n - 14 =5n + 58
9n-14=5n+58
9n-5n=58+14
4n=72 / 4
n=18
Hello! (:
9n-14=5n+58
Move all the variables to the left, using the opposite operation:
9n-5n=58+14
9n-5n=72
4n=72
Divide both sides by 4 to isolate n:
n=18

The growth of a bacteria population is modeled by the equation p(h) = 1,000(0.4h)
How long does it take for the population to reach 1,000,000? Explain or show how you know.
Answer:
you have to multiply then divide the o.4h
Step-by-step explanation:
The amount of time that is taken for the population to reach 1,000,000 will be 17.27.
What is an exponent?The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.
The growth of a bacteria population is modeled by the equation given below.
[tex]\rm p(h) = 1,000 \times e^{(0.4h)}[/tex]
Then we have
Then the amount of time which is taken for the population to reach 1,000,000 will be
[tex]\rm 1,000,000 = 1,000 \times e^{(0.4h)}\\\\1000 = e^{0.4h}[/tex]
Taking log on both sides, then we have
ln 1000 = 0.4 x h x ln e
6.91 = 0.4 x h
h = 17.27

Answer: B
Explanation: B has-235 which is in the above list of y
Answer:
C
Step-by-step explanation:
Hello Jasmine. So let's try out all of the functions starting from the first one.
For A, assuming value of x = 3. (176*3)-59 = 469, so it is incorrect.
For B, assuming value of x =3. (-59*3)-235= -412, so it is incorrect.
For C, assuming value of x=3. (-59*3)-176= -353 (which is the corresponding value of y in the table.)
Which means the correct answer is C, if you need further help please let me know.
