The two different species of plants will take 5 years to reach the same height.

Given, from the table :

Tree specie A has a:

current height = 38 inches

and its annual growth = 4 inches

Therefore, total height is:

38 + 4x .. eq (1)

Tree specie B has a:

current height = 45.5 inches

and its annual growth = 2.5 inches

Therefore, total height is:

45.5 + 2.5x .. eq (2)

Equate equation 1 and equation 2.

38 + 4x = 45.5 + 2.5x

Subtract the constants.

4x = 45.5 - 38 + 2.5x

4x = 7.5 + 2.5x

now subtract the variables.

4x - 2.5x = 7.5

1.5x = 7.5

x = 7.5/1.5

x = 5

Hence the trees will take 5 years to reach the same height.

(a) The equation to find x is :  (6x)°  + (x-8)°  = 90°

(b) The degree measure of the  complementary angles, m∠1 = 84° and m∠2 = 6°

Complementary angles are two angles whose sum is 90 degree.

Given are two complementary angles ∠1 and ∠2 whose measures are given m∠1 = (6x)° and m∠2 =(x-8)°

From the given figure we can see that sum of  ∠1 and ∠2 is 90°, which means they are complementary.

m∠1 + m∠2 = 90°

And  (6x)°  + (x-8)°  = 90°

Or      6x +x-8 = 90

7x = 90+8

7x= 98

x= 98/7 =14

Then m∠1 = (6x)° = (6*14)° = 84° and m∠2 = (x-8)° = (14-8)° = 6°

Therefore, The equation to find x is (6x)°  + (x-8)°  = 90° and measure of the  complementary angles, m∠1 = 84° and m∠2 = 6°

(COMPLETE QUESTION:in a small library there are 5 nonfiction books for every 9 fiction book there are 130 nonfiction book. How many fiction books are there in the library?)

Answer: Explanation

Step-by-step explanation:

For #1 first we have to convert all of the fractions to have the same denominator by finding the LCM(Least Common Multiple), which is 60. 1/4=15/60, 1/5=12/60, and 1/3=20/60. Then you add them up and get 47/60. You take that fraction and multiply it by 850 to get about 665.83, which is the estimate.

As for #2, I don't know sorry, I think you can just draw different lengthed lines to show the different distances traveled.

For #3 its 850/9 which is about 94.44

#4 I would recommend stopping through the night because they have about 184 miles to go and since they would only complete about 94 of those miles and would still have to drive tomorrow, they might as well do it all tomorrow.

Probability of an even number product as requested = 7/10 = .7 = 70%

The probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.

Combinations of 2 digits from among 5 = 5!/(3!)(2!) = 10. Those combinations of 2 digits resulting in an even number product are even*even and even*odd. There are 2 even digits, (2,4), and 3 odd digits, (1,3,5).

Combinations of 2 even digits and 3 odd digits = 3*2 = 6. Combinations of 2 even digits = 1*1 = 1. there are thus 6+1 = 7 distinct 2 digit products that result in even numbers from among 10 possible 2 digit products.

The yard is 6 meters wide by use of Pythagoras crossing the diagonal to create a rectangular triangle.

The formula for the Pythagoras theorem is written as c2 = a2 + b2, where c is the hypotenuse of the right triangle and a and b are its other two legs. As a result, to generate a Pythagoras triangle, the Pythagoras equation can be used to any triangle with one angle that is precisely 90 degrees.

d² = l² + w²

d = 10

l = 8

Solving for w, the width is

w² = d² - l²

So, we can replace the values with d = 10 and l = 8, to get

w² = 10² - 8²

w² = 100 - 64

w² = 36

w = 6

Hence the width of the yard is 6.

The cost of a given number of handbags - Discrete

Amount of juice in a jug over time - Continuous

Area of a field based on length - Continuous

Tires in a number of cars -Discrete

A discrete function as its name suggests has distinct or separate values against one value. That is, one at a time values are in a discrete function. So its domain and image sets will have discrete values.

A continuous function has continuous values within intervals. Its domain will be intervals having a continuous range and images will also be in a  continuous range.

We need to check if the following will have a discrete or a continuous graph:

1. The cost of a given number of handbags.

This is a discrete function as the cost and number of handbags will have discrete values. So it will have a discrete graph.

2. Amount of juice in a jug over time

This is a continuous function. The variables here are the amount of juice and time in which time, clearly, is a continuous variable. So it will have continuous values in an interval. So the amount of juice can also be measured continuously. So the graph will be continuous.

3.  Area of a field based on length

Here the length can take continuous values in an interval. So the area can also be measured continuously giving a continuous graph here.

4. Tires in a number of cars.

Number of tires and number of cars both will take only discrete values. So it can only give a discrete graph.

Answer:

46 miles

Step-by-step explanation:

First, set up an equation:

(48 + 58 + 68 + 50 + x) ÷ 5 = 54

Add the miles in the parentheses:

(48 + 58 + 68 + 50 + x) ÷ 5 = 54

48 + 58 + 68 + 50 = 224

(224 + x) ÷ 5 = 54

Multiply by 5 on each side:

[(224 + x) ÷ 5] × 5 = (54) × 5

(224 + x) = 270

Subtract 224 on each side to isolate x:

(224 + x) - 224 = (270) - 224

x = 46 miles

The equation of line that passes through the given points in  point-slope form is y - 2 = -4/3( x - 4 ).

Given the data in the question;

Point A(4, 2)

Point B(1, 6)

First, we determine the slope of the line.

Slope m = ( y₂ - y₁ )/( x₂ - x₁ )

Slope m = ( 6 - 2 )/( 1 - 4 )

Slope m = ( 4 )/( -3)

Slope m = -4/3

Next, plug the slope -4/3 and point (4,2) into the point slope formula y - y₁ = m( x - x₁ ) and simplify.

y - y₁ = m( x - x₁ )

y - 2 = -4/3( x - 4 )

Therefore, the equation of line that passes through the given points in  point-slope form is y - 2 = -4/3( x - 4 ).
