regina purchased 1.75 pounds of turkey breast from her local deli for $5.99 per pound. to the nearest cent, how much did she spend?
Answers
Answer:
Unit rate defined as the rate are expressed as a quantity of 1, such as 3 feet per second or 9 miles per hour, they are called unit rates.
As per the statement: Regina purchased 1.75 pounds of turkey breast from her local deli for $5.99 per pound.
⇒ unit rate per pound = $5.99.
by definition of unit rate;
Total she spends on turkey breast =
Substitute the given values, we get;
Total she spends on turkey breast =
Therefore, $10.50 (to the nearest cent) did she spend.

Answer:
The value of x , y using substitution method is 2 , 5
Step-by-step explanation:
Given as :
The two linear equation as
6 y - 4 x = 22 .......1
y + 2 x = 9
Let y = 9 - 2 x .......2
Now, using substitution method
Substitute the value of y from eq 2 into eq 1
i.e 6 × (9 - 2 x) - 4 x = 22
Or, 54 - 12 x - 4 x = 22
Or, 12 x + 4 x = 54 - 22
Or, 16 x = 32
∴ x =
i.e x = 2
Now, Put the value of x into eq 2
∴ y = 9 - 2 x
So, y = 9 - 2 × 2
Or, y = 9 - 4
i.e y = 5
So, The value of x , y = 2 , 5
Hence, The value of x , y using substitution method is 2 , 5 Answer
Answer:
first step : option B
second step : option D
Step-by-step explanation:
- first, Solve the second equation for y and then substitute this value into the first equation.
- after this, you will get the value of y then substitute this value in of the equations to get x.
- so, option B will be the first step to solve and option D is the second step.
- the other two steps are wrong.
- this is a standard way to solve any 2 given equations with 2 variables.

-- The smallest perimeter you can make with a certain area
is a circle.
-- The NEXT smallest perimeter with the same area is a square.
With 1-ft by 1-ft square bricks, the shortest perimeter she could
make would be by using her bricks to make it as square as possible.
Without cutting bricks into pieces, the best she could do would be
(13 bricks) x (3 bricks) .
= (13-ft) x (3-ft)
Perimeter = (2 x length) + (2 x width)
= (2 x 13-ft) + (2 x 3-ft)
= (26-ft) + (6-ft) = 32 feet <== shortest perimeter.
-- Then, the more UNSQUARE you make it, the more perimeter
it takes to enclose the same area. That means Mary has to make
a rectangle as long and skinny as she can.
The longest perimeter she can make (without cutting bricks into
pieces) is (39 bricks) x (1 brick) .
= (39-ft) x (1-ft) .
Perimeter = (2 x length) + (2 x width)
= (2 x 39-ft) + (2 x 1-ft)
= (78-ft) + (2-ft) = 80 feet .
What she'll have then is a brick path, 39 feet long and 1 foot wide,
and when you walk on it, you'll need to try hard to avoid falling off
because it's only 1 foot wide.
The largest perimeter possible is 80ft.
What is the greatest perimeter that can be made?
The greatest perimeter is obtained when we put all the bricks on a single line. That is because in this case, we do not have internal bricks that do not apport to the perimeter.
In that case, we would get a rectangle that measures 39 ft by 1ft, then the perimeter is:
P = 2*(1ft + 39ft) = 80ft
The largest perimeter possible is 80ft.

Answer:
Hence, the two numbers chosen or plotted by them are:
-75 and 75
Step-by-step explanation:
It is given that Bernita and Derek each plot a number on a number line with the properties:
- The two numbers they have plotted are unique or different.
- Also there absolute value is same.
- The sum of the absolute values of the numbers is 150.
We know that Absolute value of a positive number is a number itself and absolute value of a negative number is it's inverse.
Hence, the two numbers that satisfy the above three properties are:
-75 and 75.
Since,
|-75|=75
and |75|=75.
Hence, |-75|=|75|
Also |-75|+|75|=75+75=150
Absolute value means the positive value of a number. Absolute value of -75 is 75. Absolute value of 75 is 75.
75 + 75 = 150.
Choice a. -0 and 150 is not correct. This is because a 0 cannot have a negative value.

The bag contains 6 tiles: 2 lettered and 4 numbered. The probability of drawing a number without looking is 2/3.
Probability is the ratio of the number of favorable outcomes and a total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.
Given that,
The bag holds 6 tiles.
Among the tiles, 2 are lettered and 4 are numbered.
The task is to choose a tile from the bag without looking.
The bag contains a total of 6 tiles: 2 lettered and 4 numbered.
Therefore,
The probability of drawing a number can be calculated by dividing the number of numbered tiles by the total number of tiles.
Probability of drawing a number = (Number of numbered tiles) / (Total number of tiles)
Probability of drawing a number = 4 / 6
Simplifying this fraction, we get:
Probability of drawing a number = 2 / 3
Hence,
The probability of drawing a number from the bag is 2/3.
