Answer:

<em>the next time they'll next toll together is 180 minutes.</em>

Explanation:

Time interval for tolling = 9 min, 12 min, and 15 min.

The next time they will toll together will be the LCM of their time intervals.

we find the LCM of the three numbers as shown below

LCM of 9 = 3 x 3 = 3^{2}

LCM of 12 = 2 x 2 x 3 = 2^{2} x 3

LCM of 15 = 3 x 5

we represent each factor with the factor with the highest power i.e  3^{2}, 2^{2} and 5

the LCM is then =  3^{2}x 2^{2} x 5 = 180

<em>the next time they'll next toll together is 180 minutes.</em>

2. How does your model demonstrate the differences between the types of tectonic plates and the resulting observations in the as
jonny [76]

The model demonstrates the differences between the types of tectonic plates and the resulting observations in the asthenosphere there are two foremost sorts of tectonic plates: Oceanic and Continental. Continental crust is often fashioned of granite and is typically referred to as sial because of a large amount of silica and aluminum gift. Continental crust is much less dense than the basaltic oceanic crust, sima, which is constructed from silica and magnesium. Due to the fact it's far denser, oceanic crust plunges beneath the continental crust. The department between the 2 layers is known as the Conrad Discontinuity.

Asthenosphere, a sector of Earth's mantle mendacity beneath the lithosphere and believed to be a whole lot hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) underneath Earth's floor. Cross-section of a tectonic plate.

It's miles a layer of stable rock where the intense pressure and warmth cause the rocks to flow like a liquid. The rocks in the asthenosphere are not as dense because of the rocks in the lithosphere. This allows the tectonic plates within the lithosphere to move around on the planet's floor.

The asthenosphere is the robotically weak and ductile vicinity of the upper mantle of Earth. It lies underneath the lithosphere, between approximately 80 and two hundred km below the surface, and extends as deep as seven-hundred km. But, the decreased boundary of the asthenosphere isn't always well described.

Considering what you know about how the sea floor is formed and how it moves, from the three choices below, where would you thin
Anuta_ua [19.1K]

The area where the sea floor is oldest is in the area of the subduction zone near an ocean trench and is denoted as option C.

<h3>What is Subduction zone?</h3>

This is referred to the area which is characterized by constant collision of two or more tectonic plates.

This zone contains the oldest sea floor because the oldest ocean crust is being pushed under a continental crust and destroyed and is usually farther from the mid-ocean ridges.

01:50:58 growth Birth rates, death rates, and migration rates are all parts of measuring A population B. urban C. cultural D. ed
alina1380 [7]

Answer:

A population

Explanation:

The rate of natural increase of a population depends on birth and death rates, which are strongly influenced by the population age structure. Births occur primarily to people in the younger-adult age groups. If there are comparatively more young adults than older adults where mortality is highest, then even at replacement fertility levels (when each woman has about an average of two children) there will be more births than deaths.
