During a recent beetle infestation, two-thirds of the ash trees in the area were destroyed. If 130 trees were destroyed, how many ash trees were originally in the area?

Answers

195.

set this up as a proportion with 2/3 = 130/x
130 x 3 = 390
390 / 2 = 195

Answer:

195 Trees

Step-by-step explanation:

2/3 is just 2 of 3 parts

2 parts of the trees is 130,

so divide 130 by 2, and that's 65.

Since you know 65 + 65 is the same as 2 out of 3

Then just add 65 one more time to equal 195.

Since, 65*3 is the same as saying 1 * 3 parts

130 is equal to 2/3, so 195 is equal to 3/3.

Write the values that make the denominators zero. then solve the equation?
10/5x-5 + 1/5 = 2/x-1

Answers

Answer:

  denominators are zero for x=1

  there is no solution

Step-by-step explanation:

We suspect your equation is supposed to be ...

  10/(5x -5) +1/5 = 2/(x -1) . . . . . parentheses are required on denominators

The denominators will be zero for x=1.

This version of the equation has no solution. It simplifies to ...

  2/(x-1) + 1/5 = 2/(x -1)

  1/5 = 0 . . . . . subtract 2/(x-1) from both sides

There is no value of x that will make this equation true.

_____

Alternative interpretation

The way your equation is written, it must be interpreted according to the order of operations to be ...

  (10/5)x -5 +1/5 = (2/x) -1 . . . . x=0 makes the denominator zero

  2x -3.8 = 2/x

  2x^2 -3.8x = 2 . . . . multiply by x

  2(x^2 -1.9x +.95^2) = 2 +2(0.95^2)

  (x -0.95)^2 = 1.9025

  x = 0.95 ± √1.9025 ≈ {-0.4293, 2.3293}

Find the measures of angles 1 through 5 in the figure shown.
Its 4 PARTS​

Answers

Angle 1 = 44
Angle 2 = 136
Angle 3 = 44
Angle 4 = 136
Angle 5 = 62

The measure of angle ∠1 is 44 degrees and the measure of angle ∠5 is 62 degrees.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Vertically opposite angle - When two lines intersect, then their opposite angles are equal.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

Angle ∠1 and 46° are complementary angles. Then we have

∠1 + 46° = 90°

        ∠1 = 44°

Angle ∠1 and ∠3 are vertically opposite angles. Then we have

∠1 = ∠3 = 44°

The sum of all the angles of the triangle is 180 degrees. Then we have

∠3 + 74° + ∠5 = 180°

44° + 74° + ∠5 = 180°

                 ∠5 = 62°

Answers

Answer:

A: 16,000,000 caratsB: 4,000,000 carats

Step-by-step explanation:

If the ratio is ...

  A : B = 4 : 1

Then the ratio to the total is ...

  A : total = 4 : (4+1) = 4 : 5

  B : total = 1 : (4+1) = 1 : 5

Country A produces (4/5)×20 M carats, or 16 million carats.

x = 30

Step-by-step explanation:

Lines A and B are parallel lines and a transverse line is intersecting these lines at two distinct points.

By the definition of interior consecutive angles, sum of the measures of interior consecutive angles is 180°.

4x + 2x = 180°

6x = 180

x = 30

Therefore x = 30 will be the answer.

Can someone help me with 4?

Answers

Answer:

ok so the answer is 343

Step-by-step explanation:

so for 4) you first use PEMDAS(Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction), and you do what's in the parenthesis first, so 7^4= 2401, that is inside the parenthesis, next you do the exponent outside the parenthesis, so is (2401)^2=5764801, and then you divide the 7^5=16807, so it looks like 5764801/16807=343

hope it helps

Answer:

The Answer is 343.

Step-by-step explanation:

First- We do the parenthesis first according to PEMDAS which is 7 x 7 x 7 x 7 equals 2401.

Next- We do 2401 x 2401 which equals 5764801.

Then- We do the bottom exponent which is 7 x 7 x 7 x 7 x 7 equals 16807.

Last- We divide 5764801 by 16807 and we get 343.

Step-by-step explanation:

In the given question, some of the values are missing which is defined in the attached file please find it.

In this question, the data is used to represent a standardized​ exam's scores, which is normally spread out into the test score that is  1530 and its standard deviation 316.  

Formula:

[tex]\to z=\frac{X- \mu}{\sigma } \\[/tex]

If the value of z-score= 1930

       [tex]\to z =\frac{1930- 1530}{316 } \\\\ \to z =\frac{400}{316 } \\\\ \to z = 1.27[/tex]

The z-score is 1.27

If the value of z-score= 1250

       [tex]\to z =\frac{1250- 1530}{316 } \\\\ \to z =\frac{-280}{316 } \\\\ \to z = -0.886[/tex]

The z-score is -0.886

If the value of z-score= 2250

       [tex]\to z =\frac{2250- 1530}{316 } \\\\ \to z =\frac{720}{316 } \\\\ \to z = 2.27[/tex]

The z-score is = 2.27

If the value of z-score= 1420

       [tex]\to z =\frac{1420- 1530}{316 } \\\\ \to z =\frac{-110}{316 } \\\\ \to z = -0.348[/tex]

The z-score is = -0.348

What is geometrical series?

A geometric series is the sum of an unlimited number of terms with a fixed ratio between them.

The first term of the series is 4, while the ratio of the geometric sequence:

[tex]\rm Ratio, r = \dfrac{16}{4} = 4[/tex]

Thus, the 9th term of the geometric series can be written as,

[tex]a_n = a_1 \times r^{(n-1)}\\\\a_9 = 4 \times 4^8\\\\a_9 = 262,144[/tex]
