Answer:
A Marco le sobra 400.
Step-by-step explanation:
Marco gana 1200 mensualmente. La mitad de su dinero es entregado a su mamá.
La mitad de un número se calcula dividiendo el número por 2. Por lo que la mitad de lo ganado por Marco se calcula:
1200 ÷2= 600
Por lo que Marco entrega a su mamá 600 mensualmente, y quedan 600, obtenido de la resta entre lo ganado mensualmente y lo entregado a su madre.
De lo que le queda gasta en la tercera parte en ropa. La tercera parte de un número se calcula dividiendo el número por 3. Entonces:
600 ÷3= 200
Entonces Marco gasta 200 en ropa. Por lo que resta es 400, obtenido por la diferencia entre los 600 que poseía luego de entregar dinero a su madre y lo gastado en ropa.
Entonces, a Marco le sobra 400.

Find Arc measure of ABC
Answer:
268°
Step-by-step explanation:
[tex] In\: \odot O, [/tex] AB is diameter.
So, [tex] \widehat{AB} \:\&\: \widehat {BA}[/tex] are semicircular arcs.
[tex] \therefore m\widehat {AB} =m\widehat {BA} = 180\degree [/tex]
[tex] \because \: m\widehat {BC} = m\widehat {BA} - m\widehat {CA} [/tex]
[tex] \therefore \: m\widehat {BC} = (180-92)\degree [/tex]
[tex] \therefore \: m\widehat {BC} =88\degree [/tex]
[tex] \because m\widehat {ABC} = m\widehat {AB}+m\widehat {BC} [/tex]
[tex] \therefore m\widehat {ABC} = 180\degree+88\degree [/tex]
[tex] \therefore m\widehat {ABC} = 268\degree [/tex]
In the figure below, what is m∠2if m∠4 = 120°?

Answer:
137 ft^2
Step-by-step explanation:
The triangle has base 3 ft and height 6 ft; its area is A = (1/2)(base)(height), which here is A = (1/2)(3 ft)(6 ft) = 9 ft^2.
The lower, rectangular area has length 16 ft and width 8 ft, and thus it has the area (16)(8) ft^2, or 128 ft^2.
The total area of this irregular shape is A = 9 ft^2 + 128 ft^2 = 137 ft^2
Find the volume of the sphere.
Either enter an exact answer in terms of π or use 22/7 for π.
radius is 1/4
Answer:
0.02π cubic units
Step-by-step explanation:
Given data
Radius= 1/4
The expression for the volume is
V= 4/3* πr^3
V= 4/3*3.14*(1/4)^3
V= 4/3* π*1/64
V= 4*π*1/64*3
V=4π/192
V=0.02π cubic units
Scientists measure a bacteria population and find that it has 10,000 organisms. Five days later, they find that the population has doubled. Which function f could describe the bacteria population d days after scientists first measured it, assuming it grows exponentially?
Answer:
f(x)= 10,000(2)^x
Step-by-step explanation:
Exponential equations can be modeled by a(r)^x where a is the initial amount, r is the difference, and x is how many units the equation should be squared by.
A function that describes the bacteria population after d days would be,[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex]
What is an exponential growth?An exponential growth function is a function that grows at a constant percent growth rate.
What is an exponential growth function?f(t) = a×(1 + r)^(t)
where f(t) = exponential growth function
a = initial amount
r = growth rate
t = number of time intervals
For given example,
initially a bacteria population (a) = 10,000
Five days later, they find that the population has doubled.
d = 5, f(5) = 20,000
Assuming it grows exponentially, we find the growth rate of a bacteria population by using the formula of exponential growth function.
[tex]\Rightarrow f(d) = a\times(1 + r)^{d}\\\\\Rightarrow f(5) = 10000\times (1+r)^5\\\\\Rightarrow 20000=10000\times (1+r)^5\\\\\Rightarrow 2=(1+5)^5\\\\\Rightarrow 1+r=\sqrt[5]{2}\\\\\Rightarrow 1+r = 1.15\\\\\Rightarrow r = 1.15-1\\\\\Rightarrow \bold{r = 0.15}\\\\\Rightarrow \bold{r=15\%}[/tex]
This means, the exponential growth function would be,
[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex], where d represents number of days.

Step-by-step explanation:
It's nice to know which way the equation is going, so graphing it helps (if you can, use Desmos!)
Since the equation is facing up (BOTH SIDES UP) as x approaches infinity & negative infinity, f(x) is always going to be increasing so it is always going towards infinity.

4/8
Answer:
proper fraction
Step-by-step explanation:
if it was a mixed numebr an example: 1 4/8 If it was a imroper fraction an example: 12/8
Answer:
Proper fraction
Step-by-step explanation:
Proper fraction - A fraction with a numerator less than the denominator; proper fractions are fractions less than a whole. Ex. 5/8Mixed number - A number with an integer and a proper fraction. Ex. 2 1/2Improper fraction - A number with a numerator large than the denominator; a fraction larger than a whole. Ex. 8/5Two sides of a triangle measure 23 inches and 41 inches. Which cannot be the length of the remaining side?
Answer:
Anything over 64 inches.
Step-by-step explanation:
The Triangle Inequality states that each side of a triangle must be shorter than the sum of the other two sides.
If you call the sides a, b, c, then a + b > c, a + c > b, b + c > a.
23 + 41 = 64, so the third side must be shorter than 64 inches.

Answer:
11 73/78 ≈ 11.9359 (not 14)
Step-by-step explanation:
The similarity statement tells us ...
QS/QR = FG/FH
QS = QR·FG/FH
13x -14 = 154(55/60) = 847/6
Adding 14 = 84/6, we have ...
13x = 931/6
x = 931/78 = 11 73/78 . . . . . . . divide by 13
__
Comment on the question
You get a nice integer answer for x if the similarity statement is written ...
∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order
Then you have ...
QS/QR = FH/FG
13x -14 = 154(60/55) = 168
13x = 182
x = 14
This nice answer to a nice similarity statement leads us to believe the question has an error in it.
We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question as written. You may want to discuss this with your teacher.
