What is the difference 5 2/6 -2 4/6
Answers
Answer:
Therefore, the expression becomes:
7/1 - 2/6
Now, we need to find a common denominator for the fractions, which is 6:
7/1 - 2/6 = (76)/(16) - 2/6
= 42/6 - 2/6
= (42 - 2)/6
= 40/6
Finally, we can simplify the fraction:
40/6 = 20/3
So, the difference between 5 2/6 and -2 4/6 is 20/3.
Step-by-step explanation:
First, let's subtract the whole numbers: 5 - (-2) = 5 + 2 = 7.
Next, let's subtract the fractions: 2/6 - 4/6 = (2 - 4)/6 = -2/6.
Combining the whole number and fraction results, we have:
7 - 2/6
Now, to simplify this result further, we can express 7 as a fraction with a common denominator of 6:
7 = 7/1
Given the geometric sequence where a1 = −9 and the common ratio is 5, what is the domain for n?
Answers
The domain for n in the given Geometric sequence is the set of positive integers: {1, 2, 3, 4, 5, ...}.
In a geometric sequence, each term is obtained by multiplying the previous term by a constant value called the common ratio (r).
In the given geometric sequence, the first term (a1) is -9 and the common ratio (r) is 5. Therefore, the sequence can be written as:
-9, -9 * 5, -9 * 5^2, -9 * 5^3, ...
To determine the domain for n, we need to determine the values of n for which the sequence is defined. In a geometric sequence, the term number n represents the position of a term in the sequence.
In this case, the first term corresponds to n = 1, the second term corresponds to n = 2, and so on. The domain for n consists of all the positive integers starting from 1, as the sequence extends indefinitely.
Therefore, the domain for n in the given geometric sequence is the set of positive integers: {1, 2, 3, 4, 5, ...}.
the domain does not include zero or negative values, as these positions in the sequence do not exist. The sequence only starts from the first term (n = 1) and continues indefinitely in the positive integer domain.

The radius of a circular play ground is 77m. Calculate the distance covered by a runner is 5 complete rounds around the ground. ( ans2420) how ?
Answers
Step-by-step explanation:
To solve this problem, we need to find the circumference of the circular playground and then multiply it by the number of rounds the runner completes.
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Given that the radius of the playground is 77m, we can substitute this value into the formula to find the circumference:
Circumference = 2 * π * 77
Now, we need to calculate the distance covered by the runner in 5 complete rounds. Since one round is equal to the circumference, the distance covered in 5 rounds would be:
Distance = 5 * Circumference
Substituting the value of the circumference, we have:
Distance = 5 * (2 * π * 77)
To simplify, we can use an approximation of π as 3.14:
Distance ≈ 5 * (2 * 3.14 * 77)
Calculating further:
Distance ≈ 5 * (6.28 * 77)
Distance ≈ 5 * 483.56
Distance ≈ 2417.8
Therefore, the distance covered by the runner in 5 complete rounds around the circular playground is approximately 2417.8 meters, which can be rounded to 2420 meters (as given in the answer).
Hope this helps!
Answer:
2420
Step-by-step explanation:
Circumference = 2πr
One complete round will be equal to the circumference = 2πr
Five rounds will be five times the circumference
= 5*2πr
= 10πr
[tex]= 10 *\frac{22}{7}*77 \\\\= 10* 22* 11\\\\= 2420[/tex]

An 80-ounce bottle of apple juice contains 32 ounces of water.
Answers
Using the proportion principle , Orange Juice has a greater percentage of water than Apple juice
Calculating ProportionsTo determine which juice has a greater percent of water, we need to calculate the percentage of water in each juice.
Apple juicePercentage of water = (Water content / Total content) * 100
Water content = 32 ounces
Total content = 80 ounces
Percentage of water in apple juice = (32 / 80) * 100 = 40%
Orange juiceWater content = 48 ounces
Total content = 64 ounces
Percentage of water in orange juice = (48 / 64) * 100 = 75%
Comparing the percentages, we can conclude that orange juice has a greater percentage of water (75%) than the apple juice (40%).

The required angle is 24.5°.
Given is a right triangle with perpendicular side 16 and the base = 35 we need to find an acute angle in it,
To find the acute angle in a right triangle given the lengths of the perpendicular side and the base, you can use the tangent function.
The tangent of an angle is defined as the ratio of the length of the perpendicular side to the length of the base side.
In this case, the perpendicular side is 16 and the base is 35.
Let's denote the acute angle as θ.
Using the tangent function, we can set up the equation:
tan(θ) = perpendicular side / base
tan(θ) = 16 / 35
To find the value of θ, we can take the inverse tangent of both sides:
θ = tan⁻¹(16 / 35)
θ = 24.5°
Hence the required angle is 24.5°.

Answers
Answer:
38.9 in²
Step-by-step explanation:
You want the area of the composite figure that is an 8-inch square with a semicircle removed.
Semicircle areaThe missing semicircle has a diameter of 8 in, so a radius of 4 in. The area of that half-circle is ...
A = 1/2πr² = (π/2)(4 in)² = 8π in² ≈ 25.1 in²
Square areaThe area of the square without the semicircle removed is ...
A = s² = (8 in)² = 64 in²
Composite areaAfter removing the semicircle from the square, the remaining area is ...
A = square area - semicircle area
A = 64 in² -25.1 in² = 38.9 in²
The area of the figure is about 38.9 square inches.

(b) - [tex]y=\frac{1}{2} x-\frac{9}{2}[/tex]
Step-by-step explanation:
Given the equation of a line, which we'll call line 1, find the following.
(a) - The equation of a line, which we'll call line 2, that is parallel to line 1 and travels through the point (9,0)
(b) - The equation of a line, which we'll call line 3, that is perpendicular to line 1 and travels through the point (9,0)
Given:
[tex]3y+6x=-6[/tex]
(1) - Write the equation of line 1 in slope-intercept form
[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Slope-Intercept Form:}}\\y=mx+b\\\bullet \ m \ \text{is the slope of the line}\\\bullet \ b \ \text{is the y-intercept of the line}\end{array}\right}[/tex]
[tex]3y+6x=-6\\\\\Longrightarrow 3y=-6-6x\\\\\Longrightarrow y=-\frac{6}{3} -\frac{6}{3}x \\\\\therefore \boxed{y=-2x-2}[/tex]
Thus, we can conclude the slope of line 1 is -2.
(2) - Answering part (a)
To find a line that is parallel to line 1, the slopes must be the same, -2. Use the point-slope form for a line to find the equation for line 2.
[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Point-Slope Form:}}\\y-y_1=m(x-x_1)\\\bullet \ m \ \text{is the slope of the line}\\\bullet \ (x_1,y_1) \ \text{is a point the line passes through}\end{array}\right}[/tex]
[tex]y-y_1=m(x-x_1); \ \text{Recall that} \ m=-2 \ \text{and} \ (x_1,y_1)=(9,0)\\\\\Longrightarrow y-0=-2(x-9)\\\\\therefore \boxed{\boxed{ y=-2x+18}}[/tex]
Thus, the equation for line 2 is found.
(2) - Answering part (b)
To find a line that is perpendicular to line 1, the slope of line 3 must be the opposite-reciprocal of line 1's. Once again, use the point-slope form of a line to find the equation of line 3.
[tex]y-y_1=m(x-x_1); \ \text{Recall that} \ m=\frac{1}{2} \ \text{and} \ (x_1,y_1)=(9,0)\\\\\Longrightarrow y-0=\frac{1}{2}(x-9)\\\\\therefore \boxed{\boxed{ y=\frac{1}{2} x-\frac{9}{2} }}[/tex]
Thus, the equation of line 3 is found.

To determine the greater number of packages that can fit in the truck, we need to calculate the volume of both the packages and the part of the truck that is being filled.
The volume of a cube-shaped package:
The side length of the cube-shaped package is 1/4 feet.
The volume of a cube is given by V = s³, where s is the side length.
Therefore, the volume of each package is (1/4)³ = 1/64 cubic feet.
The volume of the part of the truck being filled:
The dimensions of the rectangular prism-shaped part of the truck are:
Length = 8 feet
Width = 6(1/4) feet = 6.25 feet
Height = 7(1/2) feet = 7.5 feet
The volume of a rectangular prism is given by V = length × width × height.
Therefore, the volume of the part of the truck being filled is:
8 × 6.25 × 7.5
= 375 cubic feet.
To calculate the greater number of packages that can fit in the truck, we divide the volume of the part of the truck by the volume of each package:

8" Box B: 6" x 3" x 12" Box C: 6" x 6" x 4" Which box would be
able to hold all the cubes if Robin's teacher had 200 cubes?
Answers
To determine which box can hold all the cubes, we need to calculate the volume of each box and compare it to the volume occupied by the cubes.
The volume of a rectangular box is calculated by multiplying its length, width, and height.
Box A:
Volume = 4" x 6" x 8" = 192 cubic inches
Box B:
Volume = 6" x 3" x 12" = 216 cubic inches
Box C:
Volume = 6" x 6" x 4" = 144 cubic inches
Since the cubes have a side length of 1 inch, the volume occupied by 200 cubes would be:
Volume of cubes = 200 cubic inches
Comparing the volumes, we find that:
- Box A has a volume of 192 cubic inches, which is less than the volume of the cubes.
- Box B has a volume of 216 cubic inches, which is greater than the volume of the cubes.
- Box C has a volume of 144 cubic inches, which is less than the volume of the cubes.
Therefore, the box that would be able to hold all 200 cubes is Box B: 6" x 3" x 12".

2.2 lbs. = 1 kg,
1kg = 1000 g
80 recipes = 3.5 cups 80
= 280 cups
1 cup of rice = 158 grams
280 cups = 158 × 280
