Answer:
0.33
Step-by-step explanation:
5.11-3.79=1.32
1.32÷4=0.33
After solving the equation, the price of each postcard will be equal to $0.33.
What is arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per information in the question,
Price of greeting card = $3.79
Total cost of greeting card as well as greeting card is $5.11
Let the price of each postcard is x.
Then, the equation will be,
$3.79 + 4x = $5.11
4x = $5.11 - $3.79
x = 1.32/4
x = $0.33

Hint There is more than one answer to this problem)
Answer: He can buy 12 shooters with $1. 20 red marbles with $1. 300 multicolored marbles.
Step-by-step explanation:
Shooters = 1 dollar is 60 cents
60 divided by 5 = 12
Red = 60 divided by 3
= 20

1. Find the general formula that gives the nth term for each of the sequences below
(remember this is NOT the recursive rule).
(a) Odd numbers:
(b) Triangular numbers:
(c) Square numbers:
9514 1404 393
Answer:
(a) an = 2n -1
(b) an = n(n +1)/2
(c) an = n^2
Step-by-step explanation:
(a) The odd numbers are an arithmetic sequence with first term 1 and common difference 2. The general term is ...
an = a1 +d(n -1)
an = 1 + 2(n -1)
an = 2n -1
__
(b) The triangular numbers are a quadratic sequence with first term 1, first first difference 2, and second differences 1.
The first few terms and differences are ...
sequence: 1, 3, 6, 10, 15, 21, 28, ... (a1 = 1)
first diff: . . . 2, 3, 4, 5, 6, 7, ... (d1 = 2)
2nd diff: . . . . 1, 1, 1, 1, 1, ... (d2 = 1)
There is a sort of general formula* that can make use of these numbers to give the general term of the sequence:
an = a1 +(n -1)(d1 +(n -2)/2(d2))
For the values we have, this gives our general term as ...
an = 1 + (n -1)(2 +(n -2)/2(1))
an = n(n +1)/2
__
(c) The general term in the sequence of square numbers is simply the square of the term number:
an = n²
_____
* There are a number of other ways to get to the general formula for triangle numbers. You can search for it, since it is well-known. You can use a quadratic regression tool on the sequence of numbers. You can develop a system of equations to find the coefficients of the quadratic equation.
The general formula given can be used to find polynomial sequences of any degree. Coefficients at successive layers in the formula are of the form (n -k)/k. The first term in parentheses following that is the first k-th difference.

Mr. Richardson would like to build a planter surrounded by a brick path (show in gray). How many square feet of brick does Mr. Richardson need? 20ft and 8 ft inside the planter 24ft and 12ft of path
Answer:
128 ft^2 needed
Step-by-step explanation:
Given
See attachment for missing details
Required
Determine the number square feet needed
First, calculate the inner area (A1)
[tex]A_1 = Length * Width[/tex]
[tex]A_1 = 20ft * 8ft[/tex]
[tex]A_1 = 160ft^2[/tex]
Next, calculate the outer area (A2)
[tex]A_2 = Length * Width[/tex]
[tex]A_2 = 24ft * 12ft[/tex]
[tex]A_2 = 288ft^2[/tex]
The area of the planter is:
[tex]Area = 288ft^2-160ft^2[/tex]
[tex]Area = 128ft^2[/tex]
Hence, he needs 128 square feet

The point (17,-9) is translated to the point 6,2 . Select the description for the translation . (in the photo above)
Answer:
B. 11 left, 11 up
Please help!!
Rotate shape A 180 about point (1,0)
The point after which shape A is rotated 180 degrees is (-1, 0).
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
Shape A is in the point (1, 0).
This means,
Shape A is in the First Quadrant.
Now,
Shape A is rotated 180 degrees.
If rotated clockwise or counterclockwise shape A will be in the same quadrant.
This means,
Shape A will be in the Third quadrant.
Now,
First quadrant coordinates = (x, y)
Third quadrant coordinates = (-x, -y)
So,
(x, y) → (-x, -y)
(1, 0) → (-1, 0)
Thus,
Shape A will be in (-2, 0).

A chicken and rice recipe is shown below. Mrs. Hughes would like to make only two-thirds of the recipe. How many cups of each ingredient does Mrs. Hughes need? 2 2/3 cups of chicken broth 1 1/2 cups of chicken 3/4 cups of rice
Answer:
See explanation below
Step-by-step explanation:
This is actually pretty easy to explain, and we all need to do is work with fractions.
So we have a recipe for chicken and rice, but the person decides to use 2/3 of the recipe. to determine the quantity of each ingredient to be used, we just need to multiply the cups of each ingredient by 2/3, and that's it.
Let's go with each ingredient, one by one:
Chicken broth 2 2/3 cups:
In this case, let's convert the 2 2/3 to a simple fraction. (We just multiply the denominator by the single number and then, sum the numerator)
2 2/3 = (3*2) + 2 / 3 = 8/3 of cups
8/3 * 2/3 = 16/9 cups of chicken.
But to do this better, let's convert this into a mix fraction:
16 : 9 = 1 and the rest is 7 so:
1 7/9 cups of chickenChicken 1 1/2 cups:
We'll do the same thing as before:
1 1/2 = (2*1) + 1 / 2 = 3/2 of cups
3/2 * 2/3 = 1
1 cup of chicken3/4 cups or rice:
3/4 * 2/3 = 1/2
1/2 cup of riceHope this helps

Fei Yen's dog eats 8 ounces of dog food each day. Fei Yen bought a 32-pound bag of dog food. How many 8-ounce servings are in 32-pound bag of dog food?
Answer:
64 servings
Step-by-step explanation:
The computation is shown below:
As dog eats 8 ounces of dog food each day
And, he purchased 32 pound bag of dog food
We know that
1 pound = 16 ounces
So for 32 pounds, the ounces would be
= 16 ×32
= 512 ounces
So, the number of 8 ounces servings would be
= 512 ÷ 8
= 64 servings
Answer:
Answer:
64 servings

Suppose Clara has a collection of old CDs. If the diameter of a CD measures about 12 centimeters, approximate the circumference of the CD. Round your answer to the nearest tenth of a centimeter.
Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm

What is the smaller angle formed by the minute and hour hands at 3:30pm?
the angle would be a 90° angle
========================================================
Explanation:
At 3:00 pm, the hour hand is pointed directly at the '3'. At 4:00 pm, the hour hand moves to point directly at the '4'.
Since 3:30 pm is the halfway point of 3:00 pm and 4:00 pm, this must mean the hour hand is halfway between the '3' and '4'.
Each little tiny tickmark on the clock represents 1 minute. From the "3" to "4", we have 5 tickmarks, so half of that is 5/2 = 2.5
The hour hand is pointing to 2.5 minutes after the 15 minute mark, meaning the hour hand is pointing to the 15+2.5 = 17.5 minute mark.
The span of time from 17.5 minutes to 30 minutes is 30-17.5 = 12.5 minutes.
Divide this over 60 minutes and we get 12.5/60 = 125/600 = 5/24
The 5/24 indicates the fractional amount of 360 degrees being taken up by this angle shown.
So, (5/24)*360 = 75 degrees is the angle measure in this diagram.
