Name the image of F(-3, 1) after being translated along the vector <5. - 1>.
Answer:
F' (2, 0 )
Step-by-step explanation:
A translation < 5, - 1 > means add 5 to the x- coordinate and subtract 1 from the y- coordinate, that is
F(- 3, 1 ) → F'(- 3 + 5, 1 - 1 ) → F'(2, 0 )
The image of the point F(-3, 1) after being translated along the vector <5, -1> is (2, 0). The process involves adding the vector components to the original point's coordinates.
Explanation:The initial point on the coordinate system is F(-3, 1). A translation moves a point by a specific vector. This vector is <5, -1>, meaning we move the point 5 units to the right and 1 unit down.
To perform the translation, we add the components of the vector to the coordinates of the original point. So, we add 5 to the x-coordinate (-3) and -1 to the y coordinate (1). This gives us the following results:
x-coordinate: -3 + 5 = 2y-coordinate: 1-1 = 0So, the image of F(-3, 1) after being translated along the vector <5, - 1> is the point (2, 0).

The floor of a rectangular room is to be tiled with 1/3 foot square tiles along a 9 3/8 foot wall. How many tiles will be needed along the wall?
Answer: Therefore, approximately 225/8 tiles will be needed along the 9 3/8 foot wall.
Step-by-step explanation:
To determine how many tiles will be needed along the 9 3/8 foot wall, we need to find the number of tiles that can fit in that space.
First, let's convert the mixed number 9 3/8 to an improper fraction. To do this, we multiply the whole number (9) by the denominator (8) and add the numerator (3):
9 * 8 + 3 = 75/8
Now, we have the length of the wall as 75/8 feet.
To find the number of tiles needed, we divide the length of the wall by the length of each tile. The length of each tile is 1/3 foot.
Dividing 75/8 by 1/3, we multiply the first fraction by the reciprocal of the second fraction:
(75/8) / (1/3) = (75/8) * (3/1)
Simplifying the calculation, we get:
(75 * 3) / (8 * 1) = 225/8
Therefore, approximately 225/8 tiles will be needed along the 9 3/8 foot wall.
To tile a 9 3/8 foot wall with 1/3 foot square tiles, 282 tiles are needed.
Explanation:The question is asking how many 1/3 foot square tiles will be needed along a 9 3/8 foot wall in your rectangular room. To find the answer, we first need to convert the length of the wall, which is given in mixed number, into an improper fraction. So, 9 3/8 is equal to 75/8 feet. Since each tile covers 1/3 foot, the number of tiles needed along the wall will be total distance divided by the length covered by each tile.
Therefore, the number of tiles = (75/8) ÷ (1/3) = (75/8) * (3/1) = 281.25
However, because we can't use a fraction of a tile, this number needs to be rounded up. Hence, you'll need 282 tiles to cover the 9 3/8 foot wall.

Step-by-step explanation:
A candy store makes a 10-lb mixture of gummy worms, candy corn, and sourballs. The cost of gummy worms is $1.00 per pound, candy corn cost $3.00 per pound, and sourballs cost $1.50 per pound. The mixture calls for three times as many gummy worms as candy corn. The total cost of the mixture is $15.00. How much of each ingredient did the store use?
Answer:
6 grams of gummy worms, 2 grams of candy corn and 2 grams of sourballs.
Step-by-step explanation:
Let the number of pounds of each ingredient be as follows:
Gummy Worms = x pounds
Candy Corn = y pounds
Sourballs = z pounds
The store makes a mixtures of 10 pounds. This means the sum of x, y and z would be 10. Setting up the equation:
[tex]x + y +z = 10[/tex] (Equation 1)
The mixture calls for 3 times as many gummy worms as candy corn. This means amount of gummy worm will be 3 times the candy corn. Setting up the Equation:
[tex]x=3y[/tex] (Equation 2)
Cost of gummy worms is $1.00 per pound, candy corn cost $3.00 per pound, and sourballs cost $1.50 per pound. So cost of x, y and z pounds would be:
1x , 3y and 1.5z, respectively. The total cost of mixture is $15. So we can set up the Equation as:
[tex]x+3y+1.5z=15[/tex] (Equation 3)
Using the value of x from Equation 2, in Equations 1 and 3 give us following two equations:
[tex]4y+z=10[/tex] By substitution in Equation 1. (Equation 4)[tex]6y+1.5z=15[/tex] By substitution in Equation 3. (Equation 5)
Multiplying the Equation 4 by 1.5 and subtracting from Equation 5 gives us:
[tex]6y +1.5z-1.5(4y+z)=15-1.5(10)\\\\ 6y+1.5z-6y-1.5z=15-15\\\\ 0=0[/tex]
When two sides of equations turn into something that is always positive, we conclude that there are infinite number of solutions. In such cases, we fix a variable and give different values to it, to find corresponding values of other variables. Lets re-write the solution in terms of z.
From Equation 4, we have:
[tex]y=\frac{10-z}{4}[/tex]
From Equation 2, we have:
[tex]x=3(\frac{10-z}{4} )[/tex]
Therefore, the solution set will be:
[tex](3(\frac{10-z}{4} ), \frac{10-z}{4} , z)[/tex]
Now in order to find any combination of ingredient, we give any value to z. Let, z is equal to 2 grams.
So,
x would be = 6 grams
y would be = 2 grams
So, one of the possible amount of ingredients that store can use is:
6 grams of gummy worms, 2 grams of candy corn and 2 grams of sourballs.
Between the time Iko woke up and lunchtime, the temperature rose by 11°. Then by the time he went to bed, the temperature dropped by 14°.
Write an addition expression for the temperature relative to when Iko woke up.
Answer: -3 degrees
Step-by-step explanation:
Lets say that the original temperature was "x."
The temperature rose by 11 degrees so it is now at 11+x.
Then the temperature fell by 14 degrees so you subtract. 11+x-14
11-14= -3 so you subtract 3 degrees from the original temperature and there fore the relative temperature is -3

The equation for line bis y = -2x + 3. Line c is the result of dilating line b by a factor
of 2 with center (0, -2). What is the equation for line c?
Answer:
[tex]y = - 2x + 8[/tex]
Step-by-step explanation:
The given equation is
[tex]y = - 2x + 3[/tex]
This is the equation of line b.
We want to find the equation of line c, after b is dilated by scale factor of 2 with center (0,-2).
Note that line c and b still have the same because they are parallel.
Also the y-intercept of b is 3.
The distance of the y-intercept of line b from the center of dilation is 5.
After a dilation by scale factor of 2, the y-intercept of c will be 2(5) =10 units from the center.
The y-intercept of c will therefore be:
10+-2=8
The equation c is

Mrs.stevens has award winning rose bushes that grow at a rate of 3/4 foot per week. Her American home rose bush currently measures 5 feet tall, while her camp David Rose bush is 4 1/2 feet tall in two weeks how tall will mrs.stevens American home rose bush measure?
Answer:
The answer would be 6.5 feet.
Pre-Thinking:
Knowing that the rose bushes grow at a rate of 3/4 feet per week, we can turn that into 0.75, a decimal.
Because, we need to know the height of the rose bush in 2 weeks, multiply 0.75 by 2.
0.75 * 2 = 1.5
Working and Stuff:
Because we only need the length of the American Home Rose Bush, which is 5 feet tall, we can discard the other rose bush.
Lastly, add 1.5 to 5.
1.5 + 5 = 6.5 feet

A recipe calls for 2/5 of a pound of chicken for each person. If there are 8 people to be fed how many pounds of chicken are required?
Answer:
3 1/5
Step-by-step explanation:
The 2 pounds of chicken are required to feed 8 people.
To find out how many pounds of chicken are required to feed 8 people, we can multiply the amount of chicken required per person by the number of people:
2/5 pound of chicken per person * 8 people = 2 pounds of chicken
Therefore, 2 pounds of chicken are required to feed 8 people.
Another way to solve this problem is to use ratios. We know that we need to feed 8 people and that we have 2/5 of a pound of chicken per person. We can set up a ratio to find out how many pounds of chicken we need:
8 people / 2/5 pound of chicken per person = x pounds of chicken
To solve for x, we can multiply both sides of the equation by 2/5 pound of chicken per person:
8 people * 2/5 pound of chicken per person = x pounds of chicken
x = 2 pounds of chicken
Therefore, 2 pounds of chicken are required to feed 8 people.
