The height of the equilateral triangle with the side x is:
h² = x² - (x/2)²h² = 3/4x²h = x*√3 / 2We have h = 30, then find the value of x:
30 = x*√3 / 2x = 60/√3x = 60√3/3x = 20√3Correct choice is B

A survey of 1250 trees in a small wood showed that 32 percent were oak trees 26 percent were birch trees and the remainder were pine trees how many pine trees were there
Answers
Answer: There were 525 pine trees.
Step-by-step explanation:
Given: Total trees = 1250
Percentage of oak trees = 32%
Percentage of birch trees = 26%
Since remaining trees are pine trees.
Percentage of pine trees = 100% - 32% - 26%
=42%
The number of pine trees = 42% of 1250
= 0.42 ×1250
= 525
Hence, there were 525 pine trees.

Answer:
7x minus 11
Step-by-step explanation:
7x would be 7 times whatever x is. then you subtract 11 from 7x. the reason you’re subracting 11 from 7x is because 11 has to be less than 7x (i understand negatives, but we’re not using that in this problem.)
Answer: (B) 7x minus 11

The Wilson Student Government sold $ 126 worth of tickets for a talent show in 3 hours. How many tickets did they sell in one hour?
Answers
Answer:
Step-by-step explanation:
They sold $42 worth of tickets in one hour. Need more information to determine the number of tickets.
The Wilson Student Government sold $42 worth of tickets in one hour. Total amount of money earned from ticket sales = $126
Number of hours during which the tickets were sold = 3 hours
Step 1: Divide the total amount of money earned by the number of hours to find the average ticket sales per hour.
Tickets sold in one hour = Total amount of money / Number of hours
Tickets sold in one hour = $126 / 3
Step 2: Perform the division.
Tickets sold in one hour = $42
So, the Wilson Student Government sold $42 worth of tickets in one hour. This means that on average, they were making $42 per hour during the three-hour period of selling tickets for the talent show.

In the year 2000, the number of bunnies in a certain forest was 320. Since that year the number of bunnies in that forest has increased at a rate of 16% per year. Write a function, f(x), that models the number of bunnies x year after the year 2000.
Answers
Answer:
f(x)=320(1.16)^x
Step-by-step explanation:
This is an exponential equation with an initial population at x=0 of 320 (because 1.16^0=1, and 320*1=320) After the first year, there are 371 bunnies. After two years, there are 431, etc etc.

Match each shape (if possibles, and one at a time) using a translation of the original shape using a coordinate rule.
Answers
For the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is given that:
The figures are given in the picture:
For the red figure: Translate 1 unit down then 3 units left.
For the yellow figure: translate 5 units down and then 2 units right
For the blue figure: Reflect the figure at the y-axis.
Thus, for the red figure: Translate 1 unit down then 3 units left, and for the blue figure: Reflect the figure at the y-axis.
