A large western state consists of 3129 million acres of land. Approximately 55% of this land is federally owned. Find the number of acres that are not federally owned
Answers
Answer:
1408.5 acres
Step-by-step explanation:
If 55% of the land is federally owned, then 100 - 55 = 45% of the land is not federally owned.
We need to find how many acres are not federally owned, in other words, we need to find how many acres represent 45% of the total 3129 acres. So, to do this we can apply a rule of three:
3129 acres ---- 100%
x acres ------ 45%
[tex]x=\frac{(3129)(45)}{100} =3129(0.45)= 1408.05[/tex]
Therefore, the total of acres that are not federally owned are 1408.5 acres.
Justo ayer fue el cumpleaños de Mauricio. Si a la edad e Mauricio, le sumo 13, al resultado le resto 10, luego al nuevo resultado lo divido entre 23 y finalmente le sumo 20, obtendré el número 21. ¿EN QUE AÑO nació mauricio?
Answers
Answer:
Mauricio nació en el año 2000.
Step-by-step explanation:
Supóngase que el cumpleaños se celebra en el año 2020, si [tex]x[/tex] es la edad actual de Mauricio, entonces la expresión matemática que traduce el enunciado del problema es:
[tex]\frac{(x+13)-10}{23} +20 = 21[/tex]
Ahora, se desarrolla y se simplifica la ecuación:
[tex]\frac{x+3}{23}+20 = 21[/tex]
[tex]\frac{x+3}{23} = 1[/tex]
Se despeja [tex]x[/tex]:
[tex]x +3 = 23[/tex]
[tex]x = 20[/tex]
Mauricio tiene 20 años.
Ahora, el año de nacimiento de Mauricio es la sustracción de la edad de Mauricio del año actual:
[tex]y = 2020-20[/tex]
[tex]y = 2000[/tex]
Mauricio nació en el año 2000.

Coffee vs. Tea
A café by Lindsay's house sells coffee and tea. They are trying to make the most amount of money
possible. In other words they are trying to maximize profit. They asked me to look at their sales
receipts and figure out what they should do. But they had a few limitations on what could be done.
Constraint #1: The Baristas (the people who makes the coffee) can only reasonably serve 90 cups
per shift. It can be 90 cups of coffee, 90 cups of tea or a mixture of the two.
Constraint #2: Coffee costs $3 per cup and Tea costs $2. In order to stay on track to pay their
bills, the owners would like to sell at least $120 worth of beverages every shift.
Constraint #3: They have a limited supply of coffee and tea that gets delivered every day. If they
don't want to sell out (And annoy customers) they can sell no more than 70 cups of tea per shift.
Constraint #4: Similar to the last constraint, they can only sell 60 cups of coffee per shift before
they sell out.
Question: How much tea and how much coffee should they sell every shift in order to maximize
profits? They make $1.10 on each cup of coffee and $.90 on each cup of tea.

why isnt 16:14 equivlant to 64:60
Answers
Answer:
The scalar used does not exist in the real number system.
Step-by-step explanation:
The ratio 16:14 is not equivalent to the ratio 64:60 because the scalar used does not exist in the real number system.
Note, that the ratio 64:60 can be scaled down by 4 to be the ratio 16:15, which is not the ratio 16:14.
In order to scale 64:60 to 16:14 or vise versa, you'd have to use a number that simply does not exist in the real number system.

Angle A and angle B are supplementary angles. If
angle B is 30° more than four times angle A, find
angle A and angle B.
Answers
Answer:
Angle A is 30
Angle B is 150
Step-by-step explanation:
So we have the supplementary angles A and B. In other words:
[tex]A+B=180[/tex]
We are also told that Angle B is 30 more than four times Angle A. In an equation, this is:
[tex]B=30+4A[/tex]
We now have a system of equations. Solve by substitution of B into the first equation:
[tex]A+B=180[/tex]
[tex]A+(30+4A)=180[/tex]
Combine like terms:
[tex]5A+30=180[/tex]
Subtract 30:
[tex]5A=150[/tex]
Divide by 5:
[tex]A=30[/tex]
So, Angle A is 30 degrees.
And since the angles are supplementary, this means that Angle B is 180 minus 30 or 150 degrees.

Brandon wants to buy a new bike. The model he likes is on sale for 15% off its original price. His parents agree to pay for $50 of the cost. If the original cost of the bike is x dollars, which of the expressions below represent the amount Brandon has to pay
Discount on price = 15%
Amount parents agreed to pay = $50
Cost of bike = x
Discount on bike = 0.15x
Cost after discount is removed = (x - 0.15x) = 0.85x

In a game experience, the experience of monsters, E, is measured by the formula E= 100M/L, where M=number monsters and L=level of monsters. Solve the formula for L
Answers
Answer: The formula solved for L is E/100M = L.
Step-by-step explanation:
So far we have the givens:
E, is measured by the formula E = 100M/L, where M = number monsters and L= level of monsters and solve for L.
Thus, isolate L to solve for it.
E = 100M/L
Divide each side by 100M to get rid of it and to free L.
E/100M = L

8 gal to 9 1/3 gal write ratio in lowest form with whole numbers in numerator and denominator
Answers
Answer:
[tex]\bold{\dfrac{6}{7}}[/tex]
Step-by-step explanation:
Given ratio is:
8 gal to [tex]9\frac{1}3[/tex] gal
To find:
Ratio in Lowest form with whole numbers in numerator and denominator.
Solution:
First of all, let us convert [tex]9\frac{1}3[/tex] to simple [tex]\frac{p}{q}[/tex] form:
Formula:
[tex]a\dfrac{b}{c} = \dfrac{a\times c+b}c[/tex]
Using the formula, we get:
[tex]9\dfrac{1}{3} = \dfrac{9\times 3+1}{3} = \dfrac{28}{3}[/tex]
Now, let us have a look at the ratio:
[tex]8 : \dfrac{28}{3}[/tex]
Any ratio, [tex]p:q[/tex] can be written as [tex]\frac{p}{q}[/tex].
Writing given ratio as per above:
[tex]\dfrac{8}{\dfrac{28}{3}}\\\Rightarrow \dfrac{8 \times 3}{28}\\\Rightarrow \dfrac{2\times 3}{7}\\\Rightarrow \bold{\dfrac{6}{7}}[/tex]
Therefore, the answer is
[tex]\bold{\dfrac{6}{7}}[/tex]

A store donates 3% of total sales to a charity. Mr. Winn bought 4 jackets at the store. Each jacket had a price of $150. How much money did the store donate to charity because of the jackets Mr. Winn bought?
Answers
Answer: The donated $18
Step-by-step explanation:
If each jacket cost $150 then multiply 150 by 4 to find out the total that the store received.
150 * 4 = 600
Now find 3% of 600 to find out how much they donated to the charity.
3% * 600 = $18
