A rectangular section of wilderness will be set aside for a new wildlife refuge. It's dimensions are 5.2 × 105meters by 3.7 × 106meters. Find the area of the land in square meters.
Answer:
19.24*10^11metersStep-by-step explanation:
Given the dimensions are
length= 5.2 × 10^5meters
width= 3 .7 × 10^6meters
We know that area is given as
Area=length * width
Area=5.2 × 10^5* 3 .7 × 10^6
Area= 5.2*3.7*10^5+6
Area=19.24*10^11meters
Therefore the area is 19.24*10^11meters

x= -6a basketball pole is 10 feet high and cast a 12 foot shadow .a player standing nearby is 5 feet tall .how long is the player's shadow ?
Answer:
6 feet
Step-by-step explanation: If a 10 foot object casts a 12 foot shadow, that means the shadow is 1.2 times the objects height. If the person is 5ft tall 5 x 1.2 = 6 feet
Answer:
6 ft. Shadow
Step-by-step explanation:
I am not 100% sure if this is correct but hopefully it is!
If something 10ft. high casts a 12ft. shadow then something half of 10ft. or 5 ft. would cast a 6ft. shadow.
Hope this Helps!!! :)
There are 272 students in a school and there are 7 classrooms in total. If one classroom has
8 students and the rest of the classrooms have the same number of students, how many
students are there in each of the remaining 6 classrooms? Write and solve a two-step
equation to answer the question.
Answer:
6x + 8 = 272
44 students in each of the remaining 6 classrooms
Step-by-step explanation:
There are 7 classrooms.
1 classroom has 8 students.
The remining 6 classrooms have the same number of students each.
Let the number of students in each of the 6 classrooms be x.
In all 6 classrooms combined, there are 6x students.
Now add the 8 students of the 7th classroom.
The total number of students in all 7 classrooms is 6x + 8.
We are told there are 272 students in total, so we get the following equation.
6x + 8 = 272
Now we solve the equation.
Subtract 8 from both sides.
6x + 8 - 8 = 272 - 8
6x = 264
Divide both sides by 6.
6x/6 = 264/6
x = 44
There are 44 students in each of the 6 classrooms.

The larger of two integers is 7 times the smaller. The sum of the integers is at most 60. What are the largest two integers that can make these statements true?
Answer:
Step-by-step explanation:
[tex]X_1 = 7X_2\\X_1 + X_2 \leq 60\\7X_2 + X_2 \leq 60\\8X_2 \leq 60\\[/tex]
since the two numbers are integers,
the largest the smaller number can be is 7
so our numbers are
[tex](1, 7), (2, 14), (3, 21), (4, 28), (5, 35), (6, 42), (7, 49)[/tex]
the two integers are 7, 49
The largest two numbers which make the statement true are 7 and 49.
What is a number system?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.
Given that the larger of two integers is 7 times the smaller. The sum of the integers is at most 60.
The two equations will be,
x₁ = 7x₂
x₁ + x₂ ≤ 60
7x₂ + x₂≤ 60
8x₂ ≤ 60
The collection of the numbers are (1,7),(2,14),(3,21),(4,28),(5,35),(6,42),(7,49).
The largest number is 7 in the collection.
Therefore, the largest two numbers which make the statement true are 7 and 49.

are two quadrilaterals with the same side lengths
always congruent?
Answer:
no
Step-by-step explanation:
angles must be congruent as well
Two quadrilaterals with the same side lengths not always congruent.
We need to check whether two quadrilaterals with the same side lengths
always congruent.
What are congruent shapes?Congruent shapes are shapes that are exactly the same. The corresponding sides are the same and the corresponding angles are the same. To do this we need to check all the angles and all the sides of the shapes. If two shapes are congruent they will fit exactly on top of one another.
Generally we have to put side's interior angles of one quadrilateral in correspondence with sides and angles of another and to prove that all correspondence with sides and angles of another and to prove that all corresponding pairs of sides and angles are congruent.
No, two quadrilaterals with the same side lengths not always congruent.

4 puntos) Una empresa dedicada a la venta de buzos en La Victoria, dispone para la confección de 500 m de tela algodón y 520 m de tela poliéster. Cada pantalón del buzo necesita 1 m de algodón y 2 m de poliéster; para cada casaca se necesitan 2 m de algodón y 1 m de poliéster. La ganancia por cada pantalón es de S/ 9 y la ganancia por cada casaca es de S/ 12. El fabricante sabe que sus máquinas en promedio demoran 4 minutos en confeccionar un pantalón y 10 minutos en confeccionar una casaca; él promete entregar un pedido en una semana trabajando sus máquinas de lunes a viernes 8 horas diarias.
a) Modele la función objetivo y elabore el SIL para las restricciones.
b) ¿Cuánto será el pedido máximo de buzos (casaca y pantalón) que podrá entregar en una semana de trabajo? ¿Cuánto será su ganancia máxima?
Answer:
a) Las restricciones limitantes son;
1) La duración de tiempo de 2400 minutos.
2) La tela límite (algodón) de 500 m
b) El número máximo de pedidos de buzos (chaquetas y pantalones) que podrá entregar en una semana de trabajo es de 166 pares de chaquetas y pantalones.
Su beneficio máximo es 32,2[tex]\bar 7[/tex]·S
Step-by-step explanation:
a) El número de horas al día que trabaja el fabricante = 8 horas
Dado que la máquina puede hacer pantalones en 4 minutos y chaquetas en 10 minutos
Sea x = la cantidad de pantalones hechos en un día, e y = la cantidad de chaquetas hechas en una semana
Tenemos;
4 · x + 10 · y = 8 × 60 × 5 = 2400
x = y
Por lo tanto;
4 · x + 10 · y = 4 · x + 10 · x = 14 · x = 2400
x = 2400/14 ≈ 171,43, por lo tanto, redondeamos hacia abajo para dar;
x = 171
Por lo tanto, el fabricante fabrica 171 pantalones y 171 chaquetas durante la semana.
El material requerido para el pantalón = 171 m de algodón y 342 m de poliéster.
El material requerido para la chaqueta = 342 m algodón y 171 m poliéster
Para el material, tenemos [
a = Algodón, b = Poliéster
a + 2 · b = x
2 · a + b = y
3 · a + 3 · b = x + y = 2 · x
Dado que se requiere igual longitud de algodón y poliéster, dado por el coeficiente de ayb, y que la longitud del algodón es 500 m, que es menor que la longitud del poliéster, tenemos;
El número máximo de pantalones y chaqueta completos = 500/3 = 166,67 m, que se redondea a 166 pares
b) El número máximo de pares de pantalones y chaquetas que el fabricante podrá entregar en una semana de trabajo = 166 pares
Por tanto, el beneficio máximo será
La ganancia máxima = 166 × (S / 9 + S / 12) = 581 · S / 18 = 32.2[tex]\bar 7[/tex]·S.

Answer:
m<3 = 82°, m<2 = 98°, m<4 = 98°
Step-by-step explanation:
360 - Overall Sum
m<1 = m<3 (They are symmetrical)
m<2 = m<4 (They are symmetrical)
if m<1 = 82°, then m<3 = 82° [= 164]
360 - 164 = 196
if m<2 = ?°, then m<4 = ?° [= 196]
196/2 = 98

The type of relationship expressed below is an INEQUALITY
Step-by-step explanation:
To solve it (though it isn't asked for but may help in the future) you would have to combine like terms.
Add 3.0 and 2, you get 5.
5 isn't greater than 10 so this inequality would be incorrect.
