Answers
Answer:
The mapping diagram above is a function since there are no two values (integers) in the range (Set B) where there is only one value (integer) in the domain (Set A) mapped unto them
Step-by-step explanation:
By definition a function is an association between the individual elements within two sets such that all element in one set is mapped to precisely one element of the other set
In the given example, all the elements in Set A are mapped to exactly one element of the Set B
That is the function from A to B is the set C (-1, -4), (9, 5), (1, 4), whereby the first component of the ordered pair in the set C are the elements of the set A.
The mapping diagram above is a function since there are no two values in set B where there is only one value in Set A mapped to them.
A function has a very unique attribute of having one output attributed to each input. The Set A is the domain while set B denotes the range. Hence, each value in the domain would have exactly one value in the range which would be different for each value in the domain.Therefore, since the mapping diagram illustrates a 1 input to 1 output relationship, then it is a function.

Find the width and height of a 54 inch TV with the aspect ratio of 4:3. Then , find the area of the screen. You must draw and label a picture to help show ur work.
Answers
Answer:
The area of the screen is 1399.68 in²
Step-by-step explanation:
The given parameters are;
The size of the TV = 54 inch
The aspect ratio of the TV screen = 4:3
The size of the TV is given as the length, of the diagonal, therefore, we have;
The aspect ratio = Length, L:Width, W = 4/3 = L/W
L² + W² = 54²..................(1)
L/W = 4/3.........................(2)
Therefore, 3×L = 4×W
L = 4×W/3
Substituting the value of L in equation (1), we have;
(4×W/3)² + W² = 54²
16/9×W² + W² = 54²
25/9×W² = 54²
W² = 54²×9/25 = 1049.76
W = 32.4 inches
The length, L = 4×W/3 = 4×32.4/3 = 216/5 inches = 43.2 inches
The area of the screen = 43.2 inches × 32.4 inches = 1399.68 in²
The area of the screen = 1399.68 in².
A cube has volume of 7^3 cubic centimeters. What is its surface area
Answers
294
reason:
the edge length is 7
multiply 7x7 to get the area of each face of the cube, 49
multiply 49 by the number of faces, 6, to get 294
Answer:
294
Step-by-step explanation:
The volume of a cube is calculated by multiplying one
of its equal edge with itself three times which is shown as a^3
If the volume of the given cube is = 7^3 then the edge length is = 7
To find the surface area we we multiply the square of the edge by 6
6 × 7^2 = 294
An object is moving at a speed of 3 kilometers every 5 days. Express this speed in yards per hour. Round your answer to the nearest tenth
Answers
Answer: 27.3 yards per hour
Step-by-step explanation:
First convert 3 kilometers to yards
3 km to yards is 3280.84
now we have to convert 5 days to hours. If there are 24 hours per day then we will multiply 24 by 5 to determine hours are in 5 days
5 * 24 = 120 hours
Now divide divide 3280.84 by 120 to find the speed in yards per hour
3280.84 / 120 = 27.34 yards per hour
27.34 rounded to the nearest tenth is 27.3
The object is moving at a speed of 2734.025 yards per hour.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
We know 1 kilometer is 109361 yards and one day is equal to 24 hours.
Given, An object is moving at a speed of 3 kilometers every 5 days.
∴ The object is moving at a speed of (3×109361) = 328083 yards in
(5×24) = 120 hours.
Hence in 1 hour, the object moves (328083/120) yards = 2734.025 yards.

a temperature recorded in Antarctica was -122 F. The temperature recorded in the desert was 133 F. how many degrees warmer is 133 F than 122 F
Answers
Answer:
255 F
Step-by-step explanation:
133 + 122 = 225.
So that is the answer.
133°F is 255 degrees warmer than -122°F.
To find out how many degrees warmer 133°F is than -122°F, we can subtract the two temperatures:
Temperature difference = 133°F - (-122°F)
Remember that subtracting a negative number is the same as adding its positive value, so the calculation becomes:
Temperature difference = 133°F + 122°F
Temperature difference = 255°F
So, 133°F is 255 degrees warmer than -122°F.

Ingrid Sering sells two types of garden fountains on a straight commission basis. On one fountain that sells for $869, she gets a commission of $174. On the other fountain that sells for $1,260, she gets $252.During a 3-month selling season, Ingrid sold 19 of the lower-priced fountains and 23 of the higher-priced fountains. What were her total commissions for three months
From the question above, we have the following information:
On one fountain that sells for $869 = she gets a commission of $174( the lower-priced fountains)
On the other fountain that sells for $1,260 = she gets $252 ( the higher-priced fountains)
Ingrid sold 19 of the lower-priced fountains)
1 fountain sold = $174 of commission
19 fountains sold =
$174 × 19
= $3,306
She also sold 23 of the higher-priced fountains)
1 higher priced fountains = $252
23 higher priced fountains =
$252 × 23
= $5,796
Hence, the Total commission Ingrid made = Total commission on Lower priced fountains + Total commission on Higher priced fountains
= $3,306 + $5,796
= $9,102
Therefore, the total commission Ingrid made = $9,102

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that contains 52% copper with 78 grams of pure copper.
Answers
Answer:
mass of copper in the resulting mixture = 104 grams of pure copper
Percent of the resulting mixture that is copper = 81.25%
Step-by-step explanation:
The complete question is
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that contains 52% copper with 78 grams of pure copper. How many grams of copper are in the resulting mixture? What percent of the resulting mixture is copper?
The original alloy has a mass of 50 grams,
52% of this 50 grams is copper,
mass of copper = 0.52 x 50 = 26 grams
78 grams of pure copper added will bring the mass of copper to..
mass of copper = 26 + 78 = 104 grams of pure copper
After adding 78 grams of copper to the alloy, the resultant mass of the mixture will be = original mass of alloy + mass of the pure copper added
==> 50 + 78 = 128 grams
Percentage of the resulting mixture that is copper = (total mass of copper in the mixture/total mass of mixture x 100%)
==> 104/128 x 100% = 81.25%
