Answers

It is a point. Hope this helps

Points play a crucial role in defining distances, angles, and relationships between different geometric objects, providing a foundation for the study of geometry.

In geometry, a point is a fundamental concept that represents a precise location in space. It is a basic building block from which geometric figures and shapes are constructed. A point has no size, shape, or dimensions. It is often denoted by a dot or a small letter, such as point A (A). Points are used to describe the positions of other geometric elements, such as lines, curves, and polygons. They serve as reference markers and can be connected to form line segments and rays.

what is 210 divided by 2 1/2

Answers

Answer:

210 divided 2 1/2= 84....

The 210 divided by 2 1/2 is 84.

To calculate 210 divided by 2 1/2, first, we need to convert the mixed number 2 1/2 to an improper fraction. The improper fraction for 2 1/2 is (2 * 2 + 1) / 2 = 5/2.

Now, we can perform the division:

210 ÷ 5/2

To divide by a fraction, we multiply by its reciprocal:

210 * 2/5

Now, perform the multiplication:

(210 * 2) / 5 = 420 / 5

Next, simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 5:

420 ÷ 5 = 84

The result of 210 divided by 2 1/2 is 84. So, 210 ÷ 2 1/2 = 84.

Solve for x. 20 points and I give brainliest
Pls provide work. Due in an hour

Answers

Answer:

[tex]x=5[/tex]

Step-by-step explanation:

To solve for x, we can use the Exterior Angle Theorem.

The Exterior Angle Theorem states that the exterior angle is equivalent to the sum of the two opposite, interior angles.

So, we can write the following equation:

[tex](6+25x)=(44)+(18x-3)[/tex]

Now, we just have to solve for x.

On the right, let's subtract. So:

[tex]6+25x=18x+41[/tex]

Now, let's subtract 18x from both sides. This gives:

[tex]6+7x=41[/tex]

Now, let's subtract 6 from both sides. This will yield:

[tex]7x=35[/tex]

And, finally, let's divide both sides by 7, giving us:

[tex]x=5[/tex]

And we're done!

We can use the Exterior Angle Theorem.

6 + 25x = 44 + 18x - 3

6 + 25x = 18x + 41

25x = 18x + 35

7x = 35

x = 5

Best of Luck!

t = time or duration of the investment

If we have to calculate the time of investment form the given formula,

b. The second and third car seats are appropriate for a 35 lb child.

Step-by-step explanation:

a. Model those ranges with compound inequalities

Let x represent the car seat.

i. A car seat designed for a child weighing up to  and including 25 lb is described by the inequality.

x ≤ 25

ii. A car seat designed for a child weighing between 16 lb  and 35 lb is described by the inequality.

16 < x < 35

iii. A car seat designed for a child weighing between 25 lb  and 95 lb inclusive is described by the inequality.

25 < x ≤ 95

b. Which car seats are appropriate for a  33-lb child?

Since 35 lb is included in the range of the inequalities for the second and third card seats, the second and third car seats are appropriate for a 35 lb child.

Since it is in absolute value it switches the negative to a positive so here let me show you

|6+y| = 2

If you try -4 you get 2 in a positive form so -4 is one correct.

The second correct one is -8 because 6-8 is -2 but as I was saying before how the absolute value changes it into positive, that means -2 would be switched to 2 meaning that -8 is also a correct answer.

Jillian solved the equation v + 4.3 = 7.05 using the work shown below. * v + 4.3 = 7.05 v + 4.3 − 4.3 = 7.05 + 4.3 v = 11.35 What error did Jillian make?

Answers

Answer:

Please check explanation

Step-by-step explanation:

Here, in this question, we are interested in identifying the error made by Jillian in his solution of the equation.

This error is traceable to the second step of his solution. Adding 4.3 to 7.05 and subtracting again is the same thing as not adding anything or just adding zero only.

What he should have done is to subtract the value of 4.3 from both sides of the equation. In that manner, he would have been able to isolate v on the left hand side of the equation
