Answer: after about 96 Minutes
Step-by-step explanation:
En un pueblo hay tres iglesias cuyas campanas tocan cada 15 minutos, cada 20 minutos y cada 35 minutos. Suponiendo que en este instante han coincidido tocando las tres a la vez, ¿cuándo volverán a coincidir?
Answer:
420 minutos
Step-by-step explanation:
Resolvemos esta pregunta utilizando el método mínimo común múltiple
Encontramos los múltiplos de 15, 20 y 35
Múltiplos de 15:
15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375, 390, 405, 420, 435, 450
Múltiplos de 20:
20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460
Múltiplos de 35:
35, 70, 105, 140, 175, 210, 245, 280, 315, 350, 385, 420, 455, 490
Por lo tanto,
MCM (15, 20, 35) = 420
El primer múltiplo común es el mínimo común múltiplo.
Por tanto, el tiempo en el que las 3 campanas de la iglesia volverán a coincidir = 420 minutos
what is 16/20 to the nearest hundreth
Answer:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
16 / 20 = 0.800
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 800
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule I applies, so 16/20 (or 0.800) rounded to the nearest hundredth in decimal format is:
0.80
Next, we will make 16/20 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:
0.80 = 0.80/1
Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:
(0.80 x 100) / (1 x 100) = 80/100
That's it. 16/20 rounded to the nearest hundredth is displayed below (simplified if necessary):

BD = 63
Step-by-step explanation:
[tex] \frac{2}{12} = \frac{9}{CD} \\ \\ CD= \frac{12 \times 9}{2} \\ \\ CD = 6 \times 9 \\ \\ CD = 54 \\ \\ [/tex]
BD = BC + CD = 9 + 54

The rug in Diana's dining room is 216 inches by 240 inches. She wants to put a similar-sized rug in her living room. What size rug would be similar to the dining room rug?
A. 84 inches by 96 inches
B. 108 inches by 110 inches
C. 96 inches by 118 inches
D. 72 inches by 80 inches
I"LL GIVE BRAINLIEST!!!!
Answer:
D
Step-by-step explanation:
In order for the rug to be similar to the first rug, the measurements must have the same ratio as the original measurements.
Longer over shorter: 240/216 = 10/9
Let's look at A: 96/84 = 8/7 (NOT 10/9)
Let's look at B: 110/108 = 55/54 (NOT 10/9)
Let's look at C: 118/96 = 59/48 (NOT 10/9)
Let's look at D: 80/72 = 10/9 (= 10/9)
D is similar

3. Plantea un sistema de ecuaciones y halla las dimensiones de un rectángulo cuya altura mide 2 cm más que su base y cuyo perímetro es igual a 24 cm. 4. Resuelve por el método de igualación el siguiente sistema de ecuaciones
Answer:
Height = 5
Width = 7
Step-by-step explanation:
Given that :
Height of rectangle = 2 + Width
Let width = x
Height = x + 2
Perimeter = 24 cm
Perimeter of a rectangle ;
P = 2( height + Width)
P = 24 ; Length = x + 2 ; x
24 = 2(x + 2 + x)
24 = 2(2x + 2)
24 = 4x + 4
24 - 4 = 4x
20 = 4x
x = 5
Height = 5
Width = x + 2 = 5 +2 = 7
Renee spent 1/8 of the day landscaping around the house. She spent half of the time pulling weeds. What fraction of the day did rehne spend pulling weeds?
Answer:
The fraction of the day Rehee spent pulling weeds = 1/16
Step-by-step explanation:
Let us take the fraction representing a whole day to be a whole number - 1
Renee spent 1/8 of the day landscaping around the house.
This means she spent 1/8 X 1 landscaping around the house = 1/8
She spent half of the time pulling weeds.
This means she spent 1/2 of 1/8 of 1 landscaping around the house = 1/16
1/2 X 1/8 X 1 = 1/16
The fraction of the day Rehee spent pulling weeds = 1/16

The radius of a cone is decreasing at a constant rate of 5 centimeters per minute, and the volume is decreasing at a rate of 148 cubic centimeters per minute. At the instant when the radius of the cone is 222 centimeters and the volume is 21 cubic centimeters, what is the rate of change of the height? The volume of a cone can be found with the equation V=1/3πr^2h. Round your answer to three decimal places.
Answer:
The rate of change for the height of the cone is [tex]-2.849\times 10^{-3}[/tex] centimeters per minute.
Step-by-step explanation:
We derive an expression for the rate of change for the height of the cone by differentiating the volume formula given on statement:
[tex]\dot V = \frac{\pi}{3}\cdot (2\cdot r\cdot h \cdot \dot r + r^{2}\cdot \dot h)[/tex] (1)
Where:
[tex]\dot V[/tex] - Rate of change for the volume of the cone, measured in cubic centimeters per minute.
[tex]r[/tex] - Radius of the cone, measured in centimeters.
[tex]h[/tex] - Height of the cone, measured in centimeters.
[tex]\dot r[/tex] - Rate of change for the radius of the cone, measured in centimeters per minute.
[tex]\dot h[/tex] - Rate of change for the height of the cone, measured in centimeters per minute.
If we know that [tex]\dot V = -148\,\frac{cm^{2}}{min}[/tex], [tex]r = 222\,cm[/tex], [tex]V = 21\,cm^{3}[/tex], [tex]\dot r = -5\,\frac{cm}{min}[/tex], then the rate of change for the height is:
[tex]h = \frac{3\cdot V}{\pi\cdot r^{2}}[/tex] (2)
Where [tex]V[/tex] is the volume of the cone, measured in cubic centimeters.
[tex]h = \frac{3\cdot (21\,cm^{3})}{\pi\cdot (222\,cm)^{2}}[/tex]
[tex]h \approx 4.069\times 10^{-4}\,cm[/tex]
From (1):
[tex]\frac{3\cdot \dot V}{\pi} = 2\cdot r\cdot h\cdot \dot r + r^{2}\cdot \dot h[/tex]
[tex]r^{2}\cdot \dot h = \frac{3\cdot \dot V}{\pi}-2\cdot r\cdot h\cdot \dot r[/tex]
[tex]\dot h = \frac{3\cdot \dot V}{\pi\cdot r^{2}}-\frac{2\cdot h\cdot \dot r}{r}[/tex]
[tex]\dot h = \frac{3\cdot \left(-148\,\frac{cm^{3}}{min} \right)}{\pi\cdot (222\,cm)^{2}} -\frac{2\cdot (4.069\times 10^{-4}\,cm)\cdot \left(-5\,\frac{cm}{min} \right)}{222\,cm}[/tex]
[tex]\dot h = -2.849\times 10^{-3}\,\frac{cm}{min}[/tex]
The rate of change for the height of the cone is [tex]-2.849\times 10^{-3}[/tex] centimeters per minute.

Write the equation of this linear relationship in slope intercept form, use decimals in your answer!! Please help
Answer:
[tex] y = 0.35x + 1.5 [/tex]
Step-by-step explanation:
To write an equation to represent the linear relationship in slope-intercept form, as [tex] y = mx + b [/tex], we need to determine the slope (m) and the y-intercept (b).
Find slope (m) using of the line that passes through (0, 1.5) and (100, 36.5):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{36.5 - 1.5}{100 - 0} = \frac{35}{100} = 0.35 [/tex]
The y-intercept (b) is the value of y when x = 0. It is the point where the y-axis is intercepted. Form the table, we see that y = 1.5 when x = 0. Therefore,
y-intercept (b) = 1.5
Substitute m = 0.35, and b = 1.5 into [tex] y = mx + b [/tex], to get the equation.
The equation would be:
✅[tex] y = 0.35x + 1.5 [/tex]

Answer:
3.2seconds
Step-by-step explanation:
Step one:
Robert run the 100 meter dash in 13.5 seconds
We are told that he later run same distance in 10.3 seconds
Required.
The time difference in the first dash and the second
Step two:
The first dash took 13.5 seconds
the second took 10.3 seconds
the difference = 13.5-10.3= 3.2seconds
Mike has 1 over 2. Of a pan of brownies. He will eat 1 over 4. Of it himself, and share the rest. What fractional part of the pan of brownies will Mike eat?
Answer:
1/8
Step-by-step explanation:
Amount of pan of brownies that Mike has = 1/2
Amount he will eat= 1/4 of the amount he has
Amount he will eat = 1/4 of 1/2
Amount he will eat = 1/4×1/2
Amount he will eat = 1/8
Hence he will eat 1/8 of the pan of brownies
Tessa's cumulative GPA 'for 3 semesters was 3.24 for 46 course units. Her fourth semester GPA was 3.86 for 12 course units. What is Tessa's cumulative GPA for all 4 semesters
Answer:
3.37
Step-by-step explanation:
Given that :
CUNMULATIVE GPA for 4 semesters :
First 3 semesters:
Cummulative GPA = 3.24
Number of courses = 46
4th semester:
Cummulative GPA = 3.86
Number of courses = 12
Cummulative GPA for all 4 semesters:
Sum of product of Cummulative GPA and number of courses / sum of courses
= [(3.24 * 46) + (3.86 * 12)] ÷ (46 + 12)
= (149.04 + 46.32) / 58
= 3.3682758
= 3.37
Tessa's cumulative GPA for all 4 semesters is 3.37 and this can be determined by using arithmetic operations.
Given :
Tessa's cumulative GPA 'for 3 semesters was 3.24 for 46-course units. Her fourth semester GPA was 3.86 for 12-course units.Given that cumulative GPA for 3 semesters was 3.24 for 46 courses and the fourth semester GPA was 3.86 for 12-courses then the cumulative GPA for all 4 semesters will be:
[tex]=\dfrac{(3.24\times 46)+(3.86\times 12)}{(46+12)}[/tex]
[tex]=\dfrac{149.04+46.32}{58}[/tex]
[tex]=\dfrac{195.36}{58}[/tex]
= 3.37
Tessa's cumulative GPA for all 4 semesters is 3.37.
