The tallest tree in the world is 379 feet tall. How tall will each of the trees be in the year 2030 if their models continue? Is this reasonable for each tree?.

Answer:

Step-by-step explanation:

A triangle's angles have to equal to 180 degrees , so option B is not a triangle because it equals to 175

Answer:

A. Triangle? Yes. How do I know? Triangles add up to 180 degrees, and the angles measures add up to 180.

B. Triangle? No. How do I know? The angle measures only add up to 175 degrees, so it can’t be a triangle.

C. Triangle? Yes. How do I know? A triangle = 180 degrees and the angle measures add up to 180.

Answer: (5a+b)/2

Step-by-step explanation:

1. First factor 5a^2+36ab+7b^2

=(5a+b)(a+7b)

2. Factor 2a+14b

The two can be factored out, making the equation equal to 2(a+7b).

The factored out equation is now [tex]\frac{(5a+b)(a+7b)}{2(a+7b)}[/tex]

Since there is an (a+7b) on both sides of the fraction, they cancel out. You are left with (5a+b)/2. This fraction cannot be simplified more.

To verify you can multiply (5a+b)/2 times (2a+14b). If it is correct, it should come back out as 5a^2 + 36ab +7b^2

it decreases where x is 2 and it end at where x is 5

btw [ ] these mean that they include the x (i think)

while ( ) these mean that they dont include the x, like idrk how to explain it D: but thats my best explanation

Answer:

Since the $307 is the buying price of the store which makes it 100%. The store needs to make a profit from the refrigerator so it adds a +38% on the refrigerator making it a value of 138% of $307 which is 138/100 * $307 =$423.66 but we need it to the nearest dollar which will be rounded of to $424 since it passed the .5 mark

Hello.

Let's solve this problem.

First, multiply 2 times 3x:

6x

Now, add 7 plus 8:

15

Write the expression:

6x+15

Can this expression be simplified any further?

No.

Why?

Because variables and constants are not like terms.

In this case, the variable is x, and the constant is 15.

Answer:

8-sided polygon:  octagon

Step-by-step explanation:

The formula for calculating the sum of interior angles of a polygon is:

(n − 2) × 180° (where n is the number of sides)

Therefore,

⇒ (n − 2) × 180 = 1080

⇒ n - 2 = 6

⇒ n = 8

Therefore, the polygon is 8-sided:  octagon

The polygon that has an interior angle sum of 1080° is an octagon.

To find the interior angle sum of an octagon, we can use the formula: (n - 2) * 180°, where n represents the number of sides (or vertices) of the polygon.

An octagon is a polygon with eight sides and eight angles. To determine the interior angle sum of an octagon, we use the formula (n - 2) * 180°, where n represents the number of sides.

In this case, for an octagon, the calculation is (8 - 2) * 180° = 6 * 180° = 1080°.

For an octagon, n = 8, so the interior angle sum would be (8 - 2) * 180° = 6 * 180° = 1080°.

Thus, an octagon has an interior angle sum of 1080°.

The sample size must be large enough to support an assumption that the sampling distribution of the sample proportion is approximately normal. Therefore, the correct answer is option is C.

In order to use the normal approximation, we consider both np and n( 1 - p ). If both of these numbers are greater than or equal to 10, then we are justified in using the normal approximation.

While conducting a one-sample test, the population proportion is taken as p and the given sample size is n.

For the sample data to be used for the normal approximation

n×p≥10 and

n(1-p)≥10

Condition should be met.

That means when the np and n(1-p) value is greater than 10, the entire sample can be said to behave like a normal distribution.

This can be regarded as a general rule of thumb, and typically the larger the values of np and n(1-p), the better is the approximation.

Therefore, the correct answer is option is C.

Answer:

Step-by-step explanation:

A and B are both equal (corresponding parts)

A = B

5x - 5 = 3x + 13               Add 5 to both sides

5x = 3x + 13 + 5              Combine

5x = 3x + 18                    Subtract 3x from both sides

5x - 3x = 18                     Combine

2x = 18                            Divide by 2

2x/2 = 18/2

x = 9            

Angle B

B = 3x + 13                      Let x = 9

B = 3*9 + 13

B = 27 + 13

Angle B = 40

Okay so I do this kind of weird so it might be a little confusing

What's easier for me is this.. 125 * 10 is 1250

Now there is 625 left to the problem is 625/125

Then I do 125 + 125 + 125 + 125 + 125 (Adding it 5 times so that I can see when it hits 625 is easier than dividing for me)

So you take the 10 from the first part and the 5 from the second part (Got the 5 because you added it 5 times)
10 + 5 is 15

Answer:

1/15

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 125 and 1875 is 125

Divide both the numerator and denominator by the GCD

125 ÷ 125

1875 ÷ 125

Reduced fraction:

1/15

Therefore, 125/1875 simplified to lowest terms is 1/15.

Step-by-step explanation:

Angle 1: (I solved this one last) 69 degrees :) . Because Angle 2 is 37 and we know the other existing angle is 74 we can do 74+37 and subtract that from 180.

Angle 2: 37 degrees. Because Angle 2 and the 53 degree angle add up to a right triangle (90 degrees) you can subtract 90-53 and get 37.

Angle 3: 106 degrees. Because the line is a straight line, all angles should add up to 180 degrees, and 180-74=106.

Angle 4: 21 degrees. Because we know that Angle 3 is 106 degrees, we can do (106+53) and then subtract from 180 because all angles in a triangle should equal 180 degrees.

Answer:

 [tex]\frac{144}{2025}[/tex]

Step-by-step explanation:

( 3 a b ) ² = 9 a² b²

Given that,

a = - [tex]\frac{1}{5}[/tex]

b = - [tex]\frac{4}{9}[/tex]

Now you have to replace a and b with - [tex]\frac{1}{5}[/tex] and  - [tex]\frac{4}{9}[/tex] respectively.

Let us solve now.

9 a² b² = 9 × ( - [tex]\frac{1}{5}[/tex] ) ² × ( - [tex]\frac{4}{9}[/tex] ) ²

             = 9 × [tex]\frac{1}{25}[/tex] × [tex]\frac{16}{81}[/tex]
