Answer 1

Answer:

Triangle ABC and triangle EDF

Answer 2

The similar triangles are Δ ABC ~ Δ EDF ~ Δ GHI, both the triangles are similar to Δ ABC.

What are similar triangles?

Triangles are similar when their corresponding sides are equal ratios and their corresponding angles are congruent.

Given are triangles, Δ ABC, Δ EDF and Δ GHI,

Since, in Δ ABC and Δ EDF, two angles are shown congruent therefore, both are similar.

Also,

In Δ GHI,

∠ G + ∠ I = 129°

∠ H = 180° - 129°

∠ H = 43°

Since, we get, two angles congruent in both triangles Δ EDF and Δ GHI

Therefore, both the triangles Δ EDF and Δ GHI are similar,

Now,

Since, Δ ABC ~ Δ EDF and Δ EDF ~ Δ GHI,

Therefore, Δ ABC ~ Δ EDF ~ Δ GHI,

Hence, the correct option is "Both"

Is 3 a solution to 4x - 3<5?

Answers

Answer:

To solve this

4x-3<5

4x<5+3

4x<8

x<8/4

x<2

so no, three is not a solution

Step-by-step explanation:

Answer: No

Step-by-step explanation:

X = 3

Replace the variable X with 3

4 x 3 - 3 (less than or equal to) 5

4 x 3 = 12 - 3 = 9

9 is not equal to or less than 5, thus 3 is NOT a solution

Are 5x and 5x^2 like terms? Explain your answerc​

Answers

Answer:

No.  5x and 5x² are not like terms.

When a variable is raised to two different powers, they can not be added together.

Another way to look at it is to note that:

5x + 5x² ≡ 5x(1 + x)

It is more obvious there that 1 and x are not like terms, thus neither are 5x and 5x², though they do have common factors.

A student has a container with a volume of 0.5 liter. He estimates the volume to be 0.4 liter. By what percent is the​ student's estimate​ off?

Answers

Answer:

20

Step-by-step explanation:

0.5-0.4=0.1,0.1/0.5×100= 20

The students's estimation is 80%.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given that a student has a container with a volume of 0.5 liter.

He estimates the volume to be 0.4 liter.

Now to find the percentage of estimation,

estimated volume = correct volume × required percentage / 100

0.4 = 0.5 × required percentage / 100

Required percentage = 0.4 × 100 / 0.5

Required percentage = 0.4 × 100 / 0.5

Required percentage = 80%

Therefore, the students's estimation is 80%.

HELP ILY A tree is 4 1/2 feet tall. It is expected to grow by 1 3/4
feet per year.
At this growth rate, how many years will it take for the tree to have a height greater than 40 feet? Enter the answer in the box.
years

Answers

Answer:

It will take 21 years.

Step-by-step explanation:

First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.

4.5 + 1.75x = 40

Subtract 4.5 from both sides. This cancels out the +4.5.

1.75x = 40 - 4.5

Subtract 4.5 from 40 to get 35.5.

1.75x = 35.5

Divide both sides by 1.75. This cancels out the *1.75.

x = 35.5/1.75

Expand 35.5/1.75 by multiply both the numerator and denominator by 100.

x = 3550/175

Reduce 3550/175 by canceling out 25.

x = 142/7 = 20 2/7

Go up by one from 20 to get the answer of 21 years.

Evaluate the function:

Step-by-step explanation:

To solve this, you can replace all x's with -3 and then solve to find the answer.

f(x) = x^2 - 4x

f(-3) = -3^2 - 4(-3)

f(-3) = 9 - (-12)

f(-3) = 21
