Each cup of tofu provides 4 grams of carbohydrates, 13 grams of fat, and 20 grams of protein. Finally, each cup of peanuts provides 35 grams of carbohydrates, 73 grams of fat, and 31 grams of protein. How many cups of rice, tofu, and peanuts should he eat?
Answers
♥Answer:
♥Bill needs to eat 5 Cups of rise, 1 cup of tofu and 4 cups of peanuts
♥Explanation:
♥Its simple calculations:
♥As Bill requirement is 350 grams of carbohydrates, 311 grams of Fats and 168 gram of proteins.
♥Each cup of rice provides 42 grams of carbohydrates, 0 grams of fat, and 1 gram of protein.
♥Each cup of tofu provides 4 grams of carbohydrates, 11 grams of fat, and 23 grams of protein.
♥Each cup of peanuts provides 34 grams of carbohydrates, 75 grams of fat, and 35 grams of protein.
♥If he eats 5 cups of rise than he gets 42 × 5 = 210 grams of carbohydrates. similarly he gets 0 × 5 = 0 grams of fats and 1 × 5 = 5 grams of proteins.
♥If he eats 1 cup of tofu than he gets 4 × 1 = 4 grams of carbohydrates. similarly he gets 11 × 1 = 11 grams of fats and 23 × 1 = 23 grams of proteins, and If he eats 4 cups of peanuts than he gets 34 × 4 = 136 grams of carbohydrates. Similarly he gets 75 × 4 = 300 grams of fats and 35 × 4 = 140 grams of proteins.

S varies inversely as G. If S is 4 when G is 1.8, find S when G is 6.
Answers
Given that "S" varies inversely as "G", it is an Inverse Variation Relationship. Then, it has this form:
[tex]S=\frac{k}{G}[/tex]Where "k" is the Constant of Variation.
Knowing that:
[tex]S=4[/tex]When:
[tex]G=1.8[/tex]You can substitute values and solve for "k":
[tex]\begin{gathered} 4=\frac{k}{1.8} \\ \\ (4)(1.8)=k \\ \\ k=7.2 \end{gathered}[/tex]Then, the equation that models the situation is:
[tex]S=\frac{7.2}{G}[/tex]Substituting this value of "G" into the equation and evaluating:
[tex]G=6[/tex]You get:
[tex]S=\frac{7.2}{6}=1.2[/tex]Hence, the answer is:

Seeds cost for a farmer are 40$ per acre for corn and 30$ per acre for soybeans . How many acres of each crop should the farmer plant if she wants to spend no more than 2400 on seed? Express your answer as a liner inequality with appropriate nonnegative restrictions and draw its graph
Answers
Given that:
- The seeds cost is 40$ per acre for corn.
- The seeds cost is 30$ per acre for soybeans.
- The farmer wants to spend no more than $2400.
• Let be "x" the number of acres of seeds for corn and "y" the number of acres of seeds for soybeans.
You know that the total amount of money has to be less than or equal to $2400. Therefore, you can write the following Linear Inequality to represent that situation:
[tex]40x+30y\leq2400[/tex]You can rewrite it in another form by solving for "y":
[tex]\begin{gathered} 30y\leq-40x+2400 \\ \\ y\leq\frac{-40x}{30}+\frac{2400}{30} \end{gathered}[/tex][tex]y\leq-\frac{4}{3}x+80[/tex]Since the number of acres cannot be negative:
[tex]\begin{gathered} x\ge0 \\ y\ge0 \end{gathered}[/tex]• You can identify that the boundary line is:
[tex]y=-\frac{4}{3}x+80[/tex]It is written in Slope-Intercept Form:
[tex]y=mx+b[/tex]Where "m" is the slope and "b" is the y-intercept.
In this case, you can identify that the y-intercept is:
[tex]b=80[/tex]In order to find the x-intercept, substitute this value of "y" into the equation and solve for "x" (because the y-value is zero when the line intersects the x-axis):
[tex]y=0[/tex]Then, you get:
[tex]0=-\frac{4}{3}x+80[/tex][tex]\frac{(-80)(3)}{-4}=x[/tex][tex]x=60[/tex]You can identify that the symbol of the inequality is:
[tex]\leq[/tex]It indicates that the line must be solid and the shaded region must be below the boundary line.
Knowing all this information, you can graph the inequality on the Coordinate Plane (Remember that the values of the variables must be greater than or equal to zero. Then, you must shade with a different color the region in which "x" and "y" are greater than or equal to zero).
Hence, the answer is:
- Linear Inequality:

Length = (2x+1) cm
Width = 12 cm
To solve , the Area of the rectangle = length x width i.e.
less than 108 cm^2
length x width = (2x+1) x 12 cm
Area < 108 cm^2

Kenya is driving on the highway at a speed of 75 mph. She sees an accident about 500 feet ahead and must come to a complete stop. How far will Kenya travel before coming to a complete stop? Answer to the nearest hundredth of a foot. (Use rule of thumb for reaction time: 1 foot traveled for each mile per hour of speed.)
Answers
The distance Kenya travels before coming to a complete stop found by writing equations is 425 feet
What is an equation?An equation is a mathematical statement that connects two expressions with an equal sign
The speed at which Kenya is driving = 75 mph
The distance between Kenya and the accident = 500 feet
The rule of thumb for the reaction distance = 1 ft per mile per hour of speed
The rule of thumb expressed as an equation is therefore;
Distance traveled during the reaction time = 1 × v
Where;
v = The speed of driving
The distance Kenya traveled before reacting is therefore;
r = 1 ft/mph × 75 mph = 75 feet
The distance Kenya traveled before stopping is therefore;
500 feet - 75 feet = 425 feet
500 feet – 75 feet = 425 feet
The distance Kenya travels before coming to a complete stop is 425 feet’

Answers
Answer:
cos(25) = sin(65)
sin(25) = cos(65)
tan(45) = tan(45)
Explanation:
To know which are the true statements, we will use the following identities
sin(θ) = cos(90 - θ)
cos(θ) = sin(90 - θ)
Therefore,
sin(25) = cos(90 - 25)
sin(25) = cos(65)
cos(25) = sin(90 - 25)
cos(25) = sin(65)
Additionally, tan(45) is equal to itself, so
tan(45) = tan(45)
Therefore, the true statements are
cos(25) = sin(65)
sin(25) = cos(65)
tan(45) = tan(45)
Britta made her last monthly interest-only payment on may 5. her next
payment is due on june 5. what will be the amount of that interest-only
payment?
Answers
The amount of that interest-only payment is $21.53.
Define interestsThe term "interest" refers to the extra money an investor makes on top of their investment or the extra money a borrower owes on top of the money they've been loaned. Along with the loan itself, there is an additional sum or interest that must be paid.
Interests come in two types: simple interest and compound interest.
Given,
She has been awarded a $6,000 for 10-year federal loan at 4.29%.
First interest-only payment was done on May 5.
So, on June 5 second interest-only payment is done.
Interest she paid on May 5 is,
First Interest = [tex]\frac{6000*4.29}{12*100}[/tex]
= [tex]\frac{25740}{1200}[/tex]
= $21.45
Thus, the balance after the first interest = $6000 + $21.45
= $6021.45
Interest she paid on June 5 is,
Second Interest = [tex]\frac{6021.45*4.29}{12*100}[/tex]
= [tex]\frac{25832.02}{1200}[/tex]
= $21.53
Thus, the amount of that interest-only payment is $21.53.

To add fractions you need equal bottom numbers
find the LCM ( Least common multiple of the denominators )
4 , 2 , 3 , 4 = LCM = 12
Multiply each fraction by the same numerator and denominator, to obtain 12 as a bottom number
(3/4 * 3/3) + (1/2 * 6/6) + (2/3 * 4/4) + (3/4 * 3/3)
9/12 + 6/12 + 8/12 + 9/12
Now that all fractions have the same denominator ( bottom number) you can add them.
Add the numerators ( top numbers ) and put 12 as a denominator.

Simplify ( divide both numbers by 4 )
