Jacquie bought 12 pens for her students for $10.56. If she wants to buy another 18 pens, how much will they cost?
Answers
Answer:
$15.84
Step-by-step explanation:
We can write a proportion to solve
12 pens 18 pens
------------ = -------------
10.56 cost
Using cross products
12 * cost = 10.56 * 18
12 cost = 190.08
Divide each side by 12
cost = 190.08/12
cost =15.84
Answer:
$15.84Step-by-step explanation:

Part A --
Now that the sub will be shared equally among 5 people, will each person get more or less sub? Briefly state why you think so.
Part B --
Dario decides to take each one of the 4 pieces and share it equally among the 5 of them.
First, he divides one piece into 5 equal parts and shares it, then the next one, and so on.
What fraction of the party size sub did each person get after all the parts were shared out? Briefly explain your reasoning.

Find the value of x.
Answers
Answer:
x=9.6
Step-by-step explanation:
First, we have to find a similarity statement including x with 3 other values. One that we can do is long leg/hypotenuse=long leg/hypotenuse. If we use the small triangle we can get x/12 (x being long leg, 12 being hypotenuse), and using the big triangle we can get 16/20 (16 being long, 12 being hypotenuse). So, if x/12=16/20, we can solve and get that x=9.6

the sale price of the

I need the process as well, Please answer fast!!!
Answers
Answer:
$422.50
Step-by-step explanation:
Given the following question:
35% of 650
To find the answer we must first calculate 35% of 650 by using the formula to calculate percentages. Then we will subtract that answer from the original price of the bike, which will give us our answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{35\times650}{100}[/tex]
[tex]35\times650=22750[/tex]
[tex]22750\div100=227.5[/tex]
[tex]=227.50[/tex]
Now subtract from the original price:
[tex]650[/tex]
[tex]650-227.5=422.5[/tex]
[tex]=422.50[/tex]
The bike after a 35% markdown will cost "$422.50."

Let the price of the dryer = X
The washer is 2 times that so you would have 2x
Now you have X + 2x = 993
Simplify:
3x = 993
Divide both sides by 3:
x = 331
The dryer cost 331
The washer cost 2 x 331 = 662

Answers
Using relations in a right triangle, it is found that the length of AC is of 6.43 inches.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, the length of side AC is b, which is opposite to the angle of 40º, while the hypotenuse is of 10 in, hence:
[tex]\sin{40^\circ} = \frac{b}{10}[/tex]
[tex]b = 10 \times \sin{40^\circ}[/tex]
Using a calculator:
[tex]b = 6.43[/tex]

Which equation
represents a line that passes through (2, -1/2) and has a slope of 3?
Answers
Answer:
y = 3x - 6 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
We can use y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y - intercept
They have already given the slope of the line.
m = 3
And now we have to find the y - intercept using the given coordinates.
( 2 , - 1/2 ) ⇒ ( x , y )
Let us find now.
y = m x + c
-1/2 = 3 × 2 + c
-0.5 = 6 + c
-0.5 - 6 = c
-6.5 = c
-6 1/2 = c
Now let us write the equation of the line.
y = m x + c
y = 3x - 6 [tex]\frac{1}{2}[/tex]

4.5 m by 6.3 m is the ACTUAL SIZE.
Given this, we need to divide by 40 to get the room PLAN.
