Louise bought 114 pounds of roast beef at $2.00 per pound and 212 pounds of turkey at $1.50 per pound. What was her total cost? Enter your answer in the box. $
Answers
Answer: Hello there!
Louse bought 114 pounds of roast beef at $2.00 per pound, this means that each one of the 114 pounds cost $2, then the total cost of the roast beef is $2*114 = $228.
For the turkey she bought 212 pounds at a price of $1.50 per pound, with the same reasoning as before, we need to see $1.50*212 = $318
then she spend $228 in roast beef and $318 in turkey, then the total cost is the addition of this two: $228 + $318 = $546.

It is the 6th place left of the decimal point and has a 5 in it.
All digits to the right of the 5 will become zero.
If the first digit to the right of the 5 is 5 through 9, the 5 goes up 1 to 6.
In this case, the first digit to the right of 5 is a 2, so the 5 remains as 5.

An elephant can run 1/4 of a mile in 36 seconds. At this rate, which expression can be used to determine how fast an elephant runs in miles per hour?
Answers
Answer: 25 miles per hour
Step-by-step explanation: Since elephant run 1/4 miles in 36 sec
that means in 1 sec elephant runs 1/(4×36) miles
and 1 hour=60×60 sec
that means in 1 hour elephant runs (60×60)/(4×36) miles=25 miles
i.e. elephant runs 25 miles per hour

What is the discrimination of 3x^2+6x=2
Answers
D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
You must re-write 3x^2+6x=2 in standard form: 3x^2 + 6x - 2
Here a=3, b=6 and c= -2
The discriminant is b^2 - 4ac. Here, it's 6^2 - 4(3)(-2), or 36 + 24, or 60.

what is the solution to the system of equations ?
(-1,8)
(8,-1)
(5,1/2)
(1/2,5)
Answers
Answer: The solution of the system of the equation is, (8,-1)
Step-by-step explanation:
Using substitution method
[tex]2x+4y=12[/tex] .......... (1)
[tex]y=\frac{1}{4}x-3[/tex] ......... (2)
Now we are putting equation (2) into equation (1), we get the value of 'x'
[tex]2x+4(\frac{1}{4}x-3)=12[/tex]
[tex]2x+\frac{4}{4}x-4\times 3=12[/tex]
[tex]2x-x=12+12[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now put the value of 'x' in equation (2), we get the value of 'y'
[tex]y=\frac{1}{4}x-3[/tex]
[tex]y=\frac{1}{4}\times 8-3[/tex]
[tex]y=2-3[/tex]
[tex]y=-1[/tex]
Hence, the correct option is, (8,-1)
The solution to the system of equations is (-1, 8).
Explanation:The given system of equations is:
2x + 4y = 12
y = ⅓x - 3
To find the solution to the system, we can solve it by substitution or elimination method:
Substitution Method:
From the second equation, we have y = ⅓x - 3.Substitute this value of y in the first equation.Replace y with ⅓x - 3 in the first equation: 2x + 4(⅓x - 3) = 12.Distribute 4 to both terms inside the parentheses: 2x + ⅓*4x - 12 = 12.Combine like terms: 2x + ⅓*4x = 12 + 12.Combine like terms: 2x + ⅓*4x = 24.Simplify: 2x + 4/4*x = 24.Simplify: 2x + x = 24.Combine like terms: 3x = 24.Divide both sides by 3 to solve for x: x = 8.Substitute the value of x in the second equation to find y: y = ⅓(8) - 3 = 2 - 3 = -1.Therefore, the solution to the system of equations is (-1, 8).

A farmer grows two types of grain in his fields. He has a seed budget of $18,000.00 and has spent $8,100.00 to plant wheat seed so far. If barley seed costs $47.00 per acre to plant, what is the maximum number of acres of barley the farmer can plant and still be under budget?
Answers
9,900/47=210.6
210×47= 9,870
$30 under budget
210 max acres
Answer: There is 211 number of acres of barley the farmer can plant and still be under budget.
hgfhfhfghfgh
Step-by-step explanation:
Since we have given that
Amount of budget = $18000
Expenses he spent to plant wheat = $8100
So, Total amount for acre is given by
[tex]\$18000-\$8100\\\\=\$9900[/tex]
Cost of each acre to plant = $47.00
So, the maximum number of acres of barley is given by
[tex]\dfrac{9900}{47}\\\\=210.63\\\\=211\ acres[/tex]
Hence, there is 211 number of acres of barley the farmer can plant and still be under budget.

Answer: The required number is 70.4.
Step-by-step explanation: We are given to find the number of which 31.68 is 45%.
Let x be the required number.
Then, according to the given information, we have
[tex]45\%\times x=31.68\\\\\Rightarrow \dfrac{45}{100}\times x=31.68\\\\\Rightarrow x=\dfrac{3168}{45}\\\\\Rightarrow x=70.4.[/tex]

help below i think the question that i chose is right but i want a second opinion
Answers
The starting value is 13, this is given from x=0.
So the equation is y = 7x + 13, but that's not in the list.
We'll have to manipulate it until we find the formula that's equivalent. If we move the 13 to the left and the y to the right (the signs swap as you know), we get:
-13 = 7x - y
Swap the left and the right side and you get
7x - y = -13, that's answer D!
