If a blue spruce is currently 4 feet tall and a hemlock is 6 feet tall , when would you expect the trees to be the same height.

Answers

Answer 1

Answer:

It will take 12 years for the trees to be at the same height.

Answer 2

Answer:

12 years

Step-by-step explanation:

blue spruce = 0.5 ft/yr & 4 ft tall

Hemlock = 0.33 ft/yr & 6 ft tall

x = number of years

spruce       hemlock

(4+0.5x)   =   (6+0.33x)

0.17x = 2

Answer:

[tex] \huge\: f = \frac{61}{7} \: or \: 8\frac{5}{7} [/tex]

A fish is swimming at a constant rate toward the ocean floor. The equation
y = -7x - 3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.
Which statement best describes the depth of the fish, given this equation?

A.From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.

B.From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

C.From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

D.From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second.

Answers

Answer:

C.

explanation: if the fish is swimming towards the ocean floor it's descending 7 meter per second because -7x is the constant and 3 is the y-intercept or where the fish started

Give the guy above me brainliest he is right!

Step-by-step explanation:

The variable in the given expression is "k", the operation is division, and the constant is "8".

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.

The given algebraic expression is "StartFraction k Over 8 EndFraction". This expression consists of a fraction (k/8), which represents a division operation between two quantities.

Here, the numerator of the fraction is the variable "k" and the denominator is the constant "8".

So, the variable in this expression is "k", the operation is division, and the constant is "8".

Thus, "StartFraction k Over 8 EndFraction" is an algebraic expression that represents a division operation between the variable "k" and the constant "8".

an isosceles triangle is when 2 angles are the same measure. an triangles angle equal to 180 degrees. therefore angle A is 80 degrees as well as angle B equals 80 degrees. since the angles of a triangle equal to 180 you subtract the two known angles to find angle C. So 180-80-80 which equals to 20.


Therefore angle C=20 degrees

Michael, his wife, and another couple when to Louisville Zoo to get out in the fresh air and see the animals. Each ticket cost x dollars and Michael had to pay $10 to park his car. The total price paid was $90. Write and solve an equation to determine how much each ticket cost.

Answers

90-10=80 80*4=20 there is four of them and the car ticket is 10 dollars so try to determine what the most expensive thing is which was the tickets for the couples

Step-by-step explanation:

First of all PLEASE PAY ATTENTION in class.

Secondly, I'll show you the method now.

We know that they paid 10$ for their parking and $90 altogether. So we can remove $10 from the $90. This now makes it $80.

We know that Michael, his wife and 2 other people (a couple) went to the zoo, that makes it 4 people total. We can use this number to divide with $80 making it $20. This therefore means that it was 20$ per person.

Here is my explanation in method form.

x = [tex]\frac{90-10}{4}[/tex]

x = [tex]\frac{80}{4}[/tex]

x = 20
