The price for 3 pounds of apples is $3.99. What is the unit rate?
Answer:
the unit rate is 1.33$ per pound of apples
Step-by-step explanation:
you can rewrite the word problem as
3x = 3.99.
now just divide both sides by 3.
3x / 3 = 3.99/3
x = 1.33
27x+2=2x+27

Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long. A customer came in during the morning and bought 120 centimeters of the velvet. Another customer bought an additional 14 meters during the afternoon. How much crimson velvet does Malik's shop have left? Write the answer in centimeters. centimeters of velve
Given:
Malik's arts and crafts shop has a bolt of crimson velvet 32 meters long.
Velvet purchased by first customer = 120 centimeters
Velvet purchased by second customer = 14 meters
To find:
The remaining velvet in Malik's shop.
Solution:
We know that,
1 meter = 100 cm
Using this conversion, we get
32 meter = 3200 cm
14 meter = 1400 cm
Now,
Remaining velvet in Malik's shop = (3200 - 120 - 1400) cm
= 1680 cm
Therefore, the remaining velvet in Malik's shop is 1680 cm.

A restaurant owner was experimenting with the taste of her homestyle lemon
drink. She started with 60 litres of water. She removed 15 litres of the water and
replaced it with 15 litres of pure lemon juice.
After thoroughly stirring the new mixture, she discovered that it was too
“lemony”. So she removed 10 litres of the new mixture and replaced it with 10
litres of water. She thoroughly stirred the mixture and concluded that the new
mixture was just right.
Determine the ratio of pure lemon juice to water in the final 60 litre mixture.
Answer:
Lemon juice / water = 12,5 / 47,5 or 26,31 %
Step-by-step explanation:
First step:
We got 60 liters. of water and we replace 15 liters. of water and add 15 liters of lemon juice, then our mixture is:
60 lts. of mixture ⇒ with 45 lts. is water and 15 lts. is lemon juice
The proportion of the mixture
each liter of the mixture is 0,75 lts. of water and 0,25 of lemon juice
2 step
Removing 10 lts. of mixture implies
10 lts of mixture means 7,5 lts. of water and 2,5 lts. of lemon juice
then we have
50 lts. of mixture with (45 - 7,5 = 37,5 lts.) of water and (15 - 2,5 = 12,5 ) lts. of lemon juice
third step
Addind 10 lts. of water:
60 lts. of mixture with ( 37,5 + 10 = 47,5) lts. of water and 12,5 lts. of lemon juice
Final mixture is
60 lts. of mixture with 47,5 lts. of water and 12,5 lts. of lemon juice
Proportion
Lemon juice / water = 12,5 / 47,5 or 26,32 %
I don’t know how to solve it please help
Answer:
when x=0 then f(x) = -2
when x=1 then f(x) = 3
when x=2 then f(x) = 8
Step-by-step explanation:
you just plug in the x value given to you into the equation (which is 5x-2) so for example:
if x = 0 then:
5x-2 is instead 5(0)-2 which means you multiply 5 and 0 and then substract 2 because you have to follow PEMDAS
PEMDAS is (Parenthesis, Exponents, Multiplication, Division, Addition, Substraction) which is the order of priority to be solved, so you first solve parenthesis, then exponents, then you multiply or divide, and then you add or substract
easy way to remember PEMDAS: Please Excuse My Dear Aunt Sally, OR Please End My Depression And Suffering (my favorite way to remember, don't take that seriously tho >_>)
so because you have to multiply before subtracting you multiply 5 and 0, you get 0, and then you take away 2 which is -2
remember to just plug in your values and then do PEMDAS
hope you learned something :P

The Family Arts Center charges $22 for adults, $13 for senior citizens, and $5 for children for their live performance on Sunday afternoon. This past Sunday, there paid revenue was $8526 for 670 tickets sold. There were 49 more children than adults. How many children attended. A 205 B 247 C 208 D 257
Answer:
257
Step-by-step explanation:
Let the number of Adults = x
Number of senior citizens = y
Number of children = z
x + y + z = 670 tickets
The Family Arts Center charges $22 for adults, $13 for senior citizens, and $5 for children for their live performance on Sunday afternoon.
$22 × x + $13 × y + $5 × z = $8526
22x + 13y + 5z = 8526
There were 49 more children than adults.
z = x + 49
x + y + z = 670 tickets
x + y + x + 49 = 670
2x + 49 + y = 670
y = 670 - 2x - 49
We substitute
22x + 13y + 5z = 8526
22x + 13(670 - 2x - 49) + 5(x + 49) = 8526
22x + 8710 - 26x - 637 + 5x +245 = 8526
22x + 5x - 26x + 8710 - 637 + 245 = 8526
x + 8318 = 8526
x = 8526 - 8318
x = 208
The number of Adults = 208
The number rod children is calculated as:
z = x + 49
z = 208 + 49
z = 257
The number of children = 257
Find the distance between the points with the given coordinates.√ (copy and paste the radical if necessary, no decimals)
(5, 14) and (−3, −9)
Answer:
[tex]d=\sqrt{593}[/tex]
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
We are given the points (5, 14) and (−3, −9). Substituting into the formula:
[tex]d=\sqrt{(-9-14)^2+(-3-5)^2}[/tex]
[tex]d=\sqrt{(-23)^2+(-8)^2}[/tex]
[tex]d=\sqrt{529+64}[/tex]
[tex]\boxed{d=\sqrt{593}}[/tex]
The vertices of a figure are FC -9,- 9),G-3, -6),H(-3,-9). Find the coordinates of the image after a dilation with a scale factor of 2 3 and then a translation 6 units up.
Transformation involves changing the size and position of a figure.
The new coordinates of the figure is:
[tex]\mathbf{F" = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,0)}[/tex]
The coordinates are given as:
[tex]\mathbf{F = (-9,-9)}[/tex]
[tex]\mathbf{G = (3,-6)}[/tex]
[tex]\mathbf{H = (-3,-9)}[/tex]
When the figure is dilated by 2/3, the new coordinates are:'
[tex]\mathbf{F' =\frac 23 \times (-9,-9) = (-6,-6)}[/tex]
[tex]\mathbf{G' =\frac 23 \times (3,-6) = (2,-4)}[/tex]
[tex]\mathbf{H' =\frac 23 \times (-3,-9) = (-2,-6)}[/tex]
When the figure is further translated up by 6 units, the new coordinates are:
[tex]\mathbf{F" = (-6,-6 + 6) = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,-4 + 6) = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,-6 + 6) = (-2,0)}[/tex]
Hence, the new coordinates are:
[tex]\mathbf{F" = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,0)}[/tex]
