A number is divided by 9. When
the quotient is multiplied by 6,
the product is 108. What is the
number?
Explain how you found the
answer.

Answer:

∠AMB = 54°

Step-by-step explanation:

2x + (x + 9) = 90°

3x + 9° = 90°

3x = 81°

x = 27°

∠AMB = 2x = 54°

Answer:

angle AMB is  54

Step-by-step explanation:

2x+ x+9= 90

simplify and get 27

I put 90 in RHS Because The total equals to 90.

if you want to check your work, Do this-

we have the value of x which is 27

so substitute the values and angle AMB will be 54.

Angle BMC will be 36

add them and should get 90.

The three ways of finding the x-intercept are:

By looking at the equation, we may determine the y-intercept when the equation is expressed in the slope-intercept form (y=mx+b). The y-intercept is the value of b. This is due to the fact that the y-intercept occurs when the x value is 0. Y = B when x = 0, since mx = 0 at this point.

We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable.

The formula for the x-intercept is y = 0: The x-intercept(s) can be determined by factoring or by employing the quadratic formula because ax2 + bx + c=0.

The simplified value of the given expression ⇒ [(-1 / 5 j) + (3 / 4) - 5 / 2j - (7 / 8)] is computed at ⇒ [(-27 / 10 j) - (1/ 5)]

An algebraic expression is one that was created in mathematics by using integer variables, constants, and algebraic operations.

However, since they are not produced by using integer constants and algebraic operations, transcendental numbers like such and e are not algebraic. The production of is commonly stated as a geometric expression, although the definition of e requires an infinite number of algebraic operations.

Kaj bought 3 bananas and 5 apples.

From these three pieces of information, we can set up the following two equations:

We can substitute the third equation into the first equation and get:

y+2 + y = 8

So we know that y = 3

Now we can substitute this value into the second equation and get:

x + 0.5(3) = 8

So we know that x = 5

So Kaj bought 3 bananas and 5 apples.

And also we can substitute y = 3 into the third equation and get:

Answer:

  C  68.4 cm²

Step-by-step explanation:

The area of the semicircle is given by ...

  A = 1/2π(d/2)^2 = (π/8)d^2

  A = (π/8)(9 cm)^2 ≈ 31.8 cm^2

The area of the trapezoid is given by ...

  A = 1/2(b1 +b2)h

  A = 1/2(9 cm + 5 cm)(4 cm) = 28 cm^2

Then the total area is ...

  31.8 cm^2 +28 cm^2 = 59.8 cm^2

Of the offered choices, 68.4 cm^2 is closest.

Answer:

  A. 78

Step-by-step explanation:

You want the measure of one base angle of an isosceles triangle when it is given as (6x+6)° while angle K is given as 2x°.

You don't need to solve any equations to determine the correct answer choice. You just need to understand the relationship between angles in an isosceles triangle.

The two base angles in an isosceles triangle are congruent, so neither can be more than 90°. (Eliminates choice C.)

The base angle at (6x+6) is more than 3 times angle K at (2x), so the base angle cannot be as little as 12.75. (Eliminates choices B and D.)

The only viable answer choice is A. 78°.

The sum of angles in any triangle is 180°. The two base angles in an isosceles triangle are the same measure, so we have ...

  (6x +6)° +(6x +6)° +2x° = 180°

  14x +12 = 180 . . . . . . . . . . . divide by °, collect terms

  14x = 168 . . . . . . . . . . subtract 12

  x = 12 . . . . . . . . . . divide by 14

  ∠D = (6x +6)° = (6·12 +6)° = 78°

Additional comments

We are referring to the angle marked 2x° as "angle K" because Brainly doesn't like the word a.pex to show up in an answer.

We know triangle DKT is isosceles because the sides are marked with a single hash mark. The congruent base angles are opposite the congruent sides.

An altitude from K to segment DT would divide the triangle into two congruent right triangles, each with its half of angle K being x°. Then angles K/2 and T are complementary to that, so you could write ...

  6x +6 +x = 90   ⇒   7x = 84   ⇒   x = 12   ⇒   ∠D = 90° -12° = 78°

Once again, recognition that 6x+6 is somewhat greater than x means that angle D must be somewhat more than 45°. (The larger of two things is always greater than half their sum.)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The Earth is in a constant state of change. Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.

Our planet looks very different from the way it did 250 million years ago, when there was only one continent, called Pangaea, and one ocean, called Panthalassa. As Earth’s mantle heated and cooled over many millennia, the outer crust broke up and commenced the plate motion that continues today.

The huge continent eventually broke apart, creating new and ever-changing land masses and oceans. Have you ever noticed how the east coast of South America looks like it would fit neatly into the west coast of Africa? That’s because it did, millions of years before tectonic shift separated the two great continents.

Earth’s land masses move toward and away from each other at an average rate of about 0.6 inch a year. That’s about the rate that human toenails grow! Some regions, such as coastal California, move quite fast in geological terms — almost two inches a year — relative to the more stable interior of the continental United States. At the “seams” where tectonic plates come in contact, the crustal rocks may grind violently against each other, causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.

The unit rate of constant means that for every 1 pound, the output is 1.96 dollar.

Proportionality is a relationship between two variables in which their ratio is always equal to a constant value. In mathematical terms, it can be expressed as y = kx, where y and x are the two variables, and k is the constant of proportionality.

A rate is a measure of how one quantity changes in relation to another quantity. It is usually expressed as a ratio and has units of measurement, such as miles per hour, dollars per pound, etc. A unit rate is a rate in which the second quantity is one unit of measurement.

The unit rate of the constant of proportionality is found by dividing the change in y (output) by the change in x (input).

In this case:

$9.8/5$ = $1.96$, so the unit rate of the constant of proportionality is 1.96 pounds/dollar.

It means that for every 1 pound, the output is 1.96 dollar.
