Artichokes were on sale. Five of them cost $1. At this rate, what would be the price for a dozen artichokes?
Group of answer choices
$2.52
$2.50
$2.40
Answer:
$2.40
Step-by-step explanation:
as five of artichokes caused $1, a dozen is the same number as 12, so use cross multiply and you will get the answer $2.40
cross multiply : 5 artichokes = $1
12 artichokes = x
5x = $1 x $12
5x = $12
x = 12/5
x = $2.40

Find the sales tax. Then find the total cost of the item.
Sales Tax
Selling Price $40.00 Rate of Sales Tax 3% Sales Tax ?
Answer:
tax: $1.20total cost: $41.20Step-by-step explanation:
The sales tax is found by multiplying the tax rate by the item price. The total cost will be the sum of the item price and the tax.
__
tax = 0.03 × $40 = $1.20
total cost = selling price + tax = $40 +1.20 = $41.20

Find the mean for the set of data.
0.2, 0.21, 0.17, 3.22, 0.2
Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
Answer: 0.8
Answer:
0.8
Step-by-step explanation:
The mean of the data set can be found by adding all terms together and dividing by the amount of terms there is. In this case, add all the numbers and divide by 5:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5 =
(4)/5 = 0.8
0.8 is the mean for the given set.

if h(x) = x^2-5x+7 find each value
1/3*h(-8)
if h(x) = [tex]x^{2} -5x+7[/tex] so the value of [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.
Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.
we have h(x) = [tex]x^{2} -5x+7[/tex]
So, substitute the value [tex]x=-8[/tex] in the equation,
h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]
= [tex]64+40+7[/tex]
= [tex]111[/tex]
And now we shall multiply it with [tex]\frac{1}{3}[/tex],
we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

A pharmacist has 50 g of a topical cream that contains 75% glycerine. How many grams of the cream are not glycerine?
Answer:
12.5 g

Answer:.
Step-by-step explanation:
With a coupon you can get a pair os shoes that normally costs $84 for only $72 what percentage was the discount
Given parameters:
Original selling price = $84
Discounted Selling price = $72
Unknown:
Percentage discount = ?
Solution:
To find the percentage discount;
Find the discount amount Then find the percentage discount from this value when you place it over the original selling priceDiscount = Original selling price - Discounted selling price
= $84 - $72
= $12
Now,
Percentage discount = [tex]\frac{12}{84} x 100[/tex] = 14.3%

if f(x)=2^x and g(x)=x-4. The graph of (fog)(x) is shown below. What is the range of (fog)(x)?
Answer:
C) [tex]y > 0[/tex]
Step-by-step explanation:
[tex]f(x)=2^x\\\\g(x)=x-4\\\\(f\circ g)(x)=f(g(x))=f(x-4)=2^{x-4}[/tex]
This means that the parent function, [tex]f(x)=2^x[/tex], will shift 4 units to the right along the x-axis, so this DOES NOT affect the range (nor the domain either). Thus, [tex]y > 0[/tex] would be the range.

-½n² + 18 =0
n= ____
Answer: n=6
Step-by-step explanation:
First you subtract 18 from both sides so that it become -1/2n^2=-18
Second divide both sides by -1/2 so it becomes -18/(-1/2)=n^2
Then you simplify and get n^2=36
Finally you find the square root of both side, and you get n=6

Answer: x=36
Assuming that O is the centre of the circle,
108+a+a=180(sum of the interior angles of a triangle is 180)
2a=180-108

a=72÷2
a=36
a=x (angles in the same segment are equal)

A package of 5 pairs of insulated gloves costs $43.95. What is the unit price of the pairs of gloves?
Answer:
5.89 dollars
Step-by-step explanation:
To find the unit price, we use t/q where t is the total price and q is the quantity.
Therefore, it costs 5.89 dollars for a pair of gloves.
The unit price of the pair of gloves will be $8.79 for each pair of gloves.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
A package of 5 pairs of insulated gloves costs $43.95. Then the unit price of the pairs of gloves is calculated as,
Rate = $43.95 / 5
Rate = $8.79 for each pair of gloves
The unit price of the pair of gloves will be $8.79 for each pair of gloves.

Find the area
Answer:
240 square feet
Step-by-step explanation:
The area of a composite figure can be found by adding the areas of its parts.
__
Extending the vertical line across the figure cuts off a rectangle on the left that is 18 ft long and 10 ft high. It cuts off a triangle on the right that has a base of 20 ft and a height of 24-18 = 6 ft.
The sum of the areas of these parts is ...
rectangle area + triangle area
= (10 ft)(18 ft) +1/2(20 ft)(6 ft) = 180 ft² +60 ft²
= 240 ft² . . . . area of the figure
_____
Additional comment
You can see that this is the product of the height of the rectangle and the overall length of the figure. This means the smaller triangles that stick above or below the horizontal lines would fit exactly into the spaces at the tip of the arrow, filling in a 10 ft × 24 ft rectangle.

On Monday, Jolene played basketball and made 75% of the shots she took. If she missed 7 shots, how many shots did she take? Show your work.
Answer:
She took 28 shots, 7 shots would be the remaining 25% so you multiply it by 4 to get 100% or 7 × 4 = 28
missed shots = 7 = 25% since 75% are successful
proportionality table
25% ...............7
100% ........... = 7 x 100% : 25% = 28
total = 28 shots
