Geometry question I need help with the true or false

There are 3 tolls where Stephanie pays $ 4.05.

The distance between two points is the length of the path connecting them.

Here,

Distance covered by Stephanie = 12 1/4 miles

                                                     = 12.25 miles

Distance between two toll tax = 3 1/2 miles

                                                   = 3.5 miles

Number of Tolls = Total distance covered / Distance between two tolls

                            = 12.25 / 3.5

                            = 3.5

                            ≈ 3 tolls.

Cost of 1 toll = $ 1.35

Total amount paid on toll = 3 X 1.35

                                          = $ 4.05

Thus, there are 3 tolls where Stephanie pays $ 4.05.

The surface area of the planet is 103,184,713.4 miles².

A planet has the shape of a sphere.

The first step is to determine the radius of the planet from the circumference.

Radius = circumference / (π x 2)

18,000 / (3.14 x 2) = 2,866.24 miles

Surface area of a sphere = 4πr²

4 x 3.14 x ( 2,866.24²) = 103,184,713.4 miles²

Mark BRAINLIEST

The algebraic expression for "m decreased by 47%" is m - 0.47m.

To translate "m decreased by 47%" into an algebraic expression, we first need to understand the meaning of the phrase. "Decreased by" indicates a subtraction operation, and "47%" represents 47 percent, which is equal to 0.47 in decimal form.

Let's break down the expression step by step:

"m" represents the original quantity we want to find.

"Decreased by" indicates subtraction.

"47%" is equivalent to multiplying the original value "m" by 0.47.

Combining all these elements, the algebraic expression for "m decreased by 47%" is:

m - 0.47m

Answer:

4 trees and 76 acorns.

Step-by-step explanation:

Let the amount of trees be x.

[tex]18x+4=20x-4\\\\\implies2x=8\\\\\implies x=4[/tex]

There are 4 trees, and there are [tex]18x+4[/tex] acorns or 76 acorns.

Hope you have a nice day, and also you should mark brainliest :)

Answer:

76 acorns and 4 trees

Step-by-step explanation:

Let X be the number of acorns (a) Ms. Blue Jay plans to store.

We are told that she could hide 18 acorns (a) per tree (t) which we'll write as 18a/t.  This would result in 4 leftover acorns.

We then learn that if she hides 20 acorns per tree, 20a/t, she will have space for an extra four acorns.

There are t trees in both cases.  We can write these two scenarios as:

1)  18t + 4  = X [18 acorns are in each tree, t, plus there are 4 left over.]

2)  20t -4  = X [20 acorns per tree, t, with room to store 4 more]

These two are equal to each other:

18t + 4 = 20t - 4

2t = 8

t = 4

There are 4 trees.

Since 18t+4 = X, the total number of acorns is18*4+4 = 76 acorns and 4 trees.

Check to see if 76 acorns works for the second scenario:

Will hiding 20 acorns per tree leave room for 4 acorns if there are 76 acorns?

(4 trees)*(20 acorns/tree) = 80 acorns can be stored.  If Ms. Jay only has 76 acorns, there will be room for 4 more acorns.

Answer:

Step-by-step explanation:

So if you look at the first photo I sent you'll see I marked three points. So the first point is going to be the two lines meet and the other two are going to be at 0 degrees and 48 degrees. After that you're going to draw a line to connect 2 of the dots to the middle one or the one connecting the two. After this you're going to put the protractor back on the triangle and line it up and then draw a point at 24 degrees (half of 48 degrees) and then draw a line to it. And this will be the bisector. And then after that label all the points. Also for the congruency thing just do the same thing except without an angle bisector through it.

The inequality of the bridge's legal limit 100000x + 34000y ≤ 700000

The given parameters are:

Represent the 6-axle trucks with x and the y-axle trucks with y.

So, we have the following inequality

100000x + 34000y ≤ 700000

The number of 6-axle trucks at one time

Here, we assume that y = 0.

So, we have:

100000x ≤ 700000

Divide by 100000

x ≤ 7

Hence, the number of 6-axle trucks at one time is 7

The number of 2-axle trucks at one time

Here, we assume that x = 0.

So, we have:

34000x ≤ 700000

Divide by 34000

x ≤ 20.58

Round down

x ≤ 20

Hence, the number of 2-axle trucks at one time is 20

The number of feet in the length of the handrail is 17.3 ft.

The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle

The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft  turned through 270°= (3/4) of a whole revolution

(3/4) (2pi) (3)  =  (9/2)pi ft =   4.5 pi ft

The side of the rectangle will be the rise of the staircase = 10ft

And the diagonal of the rectangle will be the length of the handrail

We can use the Pythagorean Theorem to solve this

Handrail length = √ [ (4.5 pi)^2 + 10^2 ]  ≈  17.3 ft

Answer:

  (a)  The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.

Step-by-step explanation:

The possible numbers of real zeros can be found using Descarte's Rule of Signs.

When signs of coefficients of terms of the polynomial are listed in order of decreasing degree, the number of sign changes can be counted. That number is the number of possible positive real zeros of the polynomial.

When the signs of odd-degree terms are changed, the number of sign changes becomes the possible number of negative real zeros.

The actual number of real zeros may be less by a multiple of 2. (The zeros may be complex, and complex zeros come in pairs.)

The signs of the terms in the given polynomial are ...

  + - + + + . . . . . 2 sign changes: 2 or 0 positive real zeros

When the signs of odd-degree terms are changed, they become ...

  + + + - + . . . . . 2 sign changes: 2 or 0 negative real zeros

Descarte's rule of signs lets us conclude ...

Answer: [tex]128^{\circ}[/tex]

Step-by-step explanation:

By the inscribed angle theorem, minor arc EG measures 92 degrees.

Since the circumference of a circle measures 360 degrees, arc EF measures [tex]360-140-92=128^{\circ}[/tex]

The measure of the arc EF = 128°.

Arc is that part of the circumference of the circle which is formed by two points on the circle.

The angle subtended by an arc on the center of the circle is twice that it subtends on the circumference of the circle.

So,

The measure of arc EG = 2 * 46 = 92

The measure of arc GF = 140°

The complete circle has an angle of 360° at the center

The measure of the arc EF = 360 -mEG - mGF

The measure of the arc EF = 360 - 92 -140

The measure of the arc EF = 128°.

Therefore, The measure of the arc EF = 128°.
