Answer:
number 2 is c
number 1 is d?
Step-by-step explanation:
because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35 words 35m=w
for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer
Answer:
(For your second question.):
35w=m
Step-by-step explanation:
Why?
It states in the problem itself that miles types 35 words per minute.
"w" stands for words
'm' stands for minutes.
The constant rate relies on the clearest data after all. The equation itself is enough!
Remember: 1 min = 60 seconds.

The area of the triangle is
108 m². What is the value
of x?
xm
(x+6) m
Answers
Answer:
x = 12
Step-by-step explanation:
Formula for area of a triangke is;
A = ½bh
Where;
b is base
h is height
From the triangle diagram given;
b = x + 6
h = x
Thus;
A = ½(x + 6)x
A = ½x² + 3x
Now we are told that the area is 108 m², Thus;
½x² + 3x = 108
Multiply through by 2 to get;
x² + 6x = 216
x² + 6x - 216 = 0
Using quadratic formula, we arrive at;
x = -18 or 12
x can't be negative, thus; x = 12

Answer:
x=8.16
Step-by-step explanation:
x=the money before
2x=doubled
3x=24.50
x=8.16
Answer:
The answer would be...
Step-by-step explanation:

If the length of a rectangle is 12cm and the area is 48. What's the breadth and what's the perimeter??
Answers
Answer:
1. The breadth is 4 cm
2. The perimeter is 32 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 12 cm
Area (A) = 48 cm²
1. Determination of the breadth.
Length (L) = 12 cm
Area (A) = 48 cm²
Breadth (B) =?
A = L × B
48 = 12 × B
Divide both side by 12
B = 48 / 12
B = 4 cm
Thus, the breadth is 4 cm.
2. Determination of the perimeter
Length (L) = 12 cm
Breadth (B) = 4 cm
Perimeter (P) =?
P = 2(L + B)
P = 2(12 + 4)
P = 2(16)
P = 32 cm
Thus, the perimeter of the rectangle is 32 cm
La extencion territorial de mexico es de 1960198 km2 , mientras que mocano tiene una superficie de 202.7 ha ¿cuantas veces cabe la superficie de mocano en la de mexico
Answers
Answer:
La superficie de mocano cabe 967.044 veces en la superficie de Mexico.
Step-by-step explanation:
Primero debemos convertir la unidad de la superficie (S) de mocano (m):
[tex] S_{m} = 202.7 ha*\frac{10000 m^{2}}{1 ha} = 2.027 \cdot 10^{6} m^{2} [/tex]
Ahora podemos calcular cuantas veces cabe la superficie de mocano en la de Mexico (M):
[tex] \frac{S_{M}}{S_{m}} = \frac{1.960198 \cdot 10^{9} m^{2}}{2.027 \cdot 10^{6} m^{2}} = 967.044 [/tex]
Si multiplicamos la superficie de mocano por 967.044 nos da la superficie de Mexico:
[tex] 967.044*2.027\cdot 10^{6} m^{2} = 1960198 m^{2} [/tex]
Por lo tanto, la superficie de mocano cabe 967.044 veces en la superficie de Mexico.

Can any one help? Model the pair of situations with exponential functions f and g. Find the approximate value of x that makes f(x) = g(x). f: initial value of 800 decreasing at a rate of 12% g: initial value of 20 increasing at a rate of 12%
Answers
Answer:
The given exponential functions f(x) and g(x) will be equal for the value of x as 4.1466.
Step-by-step explanation:
We need to give exponential function to the given constraints.
since f(x) is a decreasing function so
f(x) = [tex]a(1-r)^x[/tex]
where
a = Initial value
r = rate at which function is decreasing
as we are given the values of a and r such as a = 800 and r = 12%
upon substituting these values in the equation we get
f(x) = [tex]800(1-0.12)^x[/tex]
= [tex]800(0.88)^x[/tex]
similarly we will do for g(x) but the only difference in f(x) and g(x) will be that f(x) in a decreasing exponential function whereas g(x) is an increasing function.
g(x) = [tex]a(1-r)^x[/tex]
where a is initial value and r is the rate at which the function is increasing so upon substituting these values we get.
g(x) = [tex]20(1+0.12)^x[/tex] = [tex]20(1.12)^x[/tex]
Now,
we need to find the value of x for which f(x) and g(x) will be equal.
so
[tex]800 (0.88)^x = 20(1.12)^x[/tex]
[tex]40(0.88)^x = (1.12)^x[/tex]
x will be approximately 4.1466
Therefore the given exponential functions f(x) and g(x) will be equal for the value of x as 4.1466.

what is exponential form of b•b•b•c•c
Answers
Answer:
b^3 + c^2
Step-by-step explanation:
b^3 * c^2
Explanation:
Here we see that there are 3 B’s being multiplied against each other. This can be written as b^3, because b^3 also represents b*b*b.
Next, there are two c’s being multiplied against each other. This can be written as c^2, because c^2 also represents c*c.
Now that we have found what the exponents are we can multiple both b^3 and c^2 to get our final answer of:
b^3 * c^2
