Name the geometric terms modeled by a wall and the floor. (Blank 1) Blank 1 options two lines intersecting in a point • two lines intersecting in a line • two planes intersecting in a line three planes intersecting in a point
Answers
Answer: Two planes intersecting in a line
Explanation:
The wall and floor are two different planes. They meet up to form a line which is the crease between them.
A plane is a flat surface without any bends or curves to it. In theoretical terms, planes go on forever in all directions. Realistically there are limits of course. The wall or floor cannot go on forever.
Another example of two planes would be found in a book. Each page is a plane. Two adjacent pages meet up to form a line (i.e. the spine of the book is a line).

Do the following side lengths form a right triangle?
15, 15, 35
Answers
Answer:No
Step-by-step explanation:
It does not
Answer:
No
Step-by-step explanation:
given 3 sides of a triangle
using the converse of Pythagoras' identity
if the square of the longest side is equal to the sum of the squares of the other 2 sides, then the triangle is right.
longest side = 35 and 35² = 1225 , then
15² + 15² = 225 + 225 = 450
since 1225 ≠ 450 then the 3 sides do not form a right triangle.

What is the rate of return when 25 shares of Stock
A, purchased for $30/share, are sold for $825? The
commission on the sale is $6.
Rate of Return = [?] %
Give your answer as a percent rounded to the
nearest tenth.
Answers
Answer:
Based on the information given the rate of return is 10.8%.
First step is to find the shares of stock price:
Shares of stock price=25 shares×$30/share
Shares of stock price= $750
Second step is to calculate the total sold price:
Total sold price= $825+$6
Total sold price= $831
Third step is to calculate the Rate of return:
Rate of return=$831-750/$750×100
Rate of return=$81/$750×100
Rate of return=10.8%
Inconclusion the rate of return is 10.8%.

10. Fouster's Farms has 5^3fruit trees on their land. Myrna's Farms has five
times as many fruit trees as Fouster's. A commercial farm has 500 fruit
trees. Which farm has the most fruit trees?
Answers
Answer:
Myrna's Farms
Step-by-step explanation:
Fouster's Farms has 5^3 = 5 x 5 x 5 = 125 fruit trees
Myrna's Farms has 5x times this many trees = 5 x 125 = 625
commercial farm has 500 fruit trees

Zoe and Mackenzie are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Zoe is 249 miles away from the stadium and Mackenzie is 237 miles away from the stadium. Zoe is driving along the highway at a speed of 58 miles per hour and Mackenzie is driving at speed of 55 miles per hour. Let ZZ represent Zoe's distance, in miles, away from the stadium tt hours after noon. Let MM represent Mackenzie's distance, in miles, away from the stadium tt hours after noon. Write an equation for each situation, in terms of t,t, and determine whether Zoe or Mackenzie is closer to the stadium 2 hours after noon.
Answers
According to the question, the given data are as follows:
Zoe’s distance = ZZ(miles); Stadium time = tt (hours); Mackenzie’s distance = MM(miles)
Distance between Zoe and stadium = 249 miles
Distance between Mackenzie and stadium = 237 miles
Zoe speed = 58 miles per hour
Mackenzie speed = 55 miles per hour
Time = 2 hours
Using standard distance formula:
Distance = (speed)(time)
As per relative speed, distance gets added and speed gets subtracted when objects are away or parallel from each other.
ZZ = 249 -58tt
MM = 237 -55tt
When both are at the same distance, the time will be t = 4 hours
249 -58tt = 237 -55tt
tt = 4 hours

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

A die is rolled. Find the probability of the outcome. P(1 or 6 )
Answers
The required probability is 1/3
Rolling a die is an equally likely event which means that probability of getting any number on rolling a die is same. When a die is rolled, there are total six outcomes in sample space which are 1, 2, 3, 4, 5, and 6 .
If a die is rolled once, then the probability of getting 1 is 1/6, and the probability of getting 6 is also 1/6.
These two events are mutually exclusive.
Thus, the probability of getting either 1 or 6 in a single throw is,
P(A or B) = P(A) + P(B)
P(A or B) = 1/6 + 1/6 = 2/6
P(A or B) = 1/3

Point (0, 0) satisfies the inequalities
Step-by-step explanation:
Sometimes graphing is the best way to determine where the region is that satisfies both inequalities. Then you can choose a point accordingly
The graph of both inequalities is attached. The heavily shaded region in blue represents the region that satisfies both inequalities
If you look at the graph, you can see that (0, 0) falls in the heavily shaded region and therefore it satisfies both constraints
Indeed at (0, 0)
7(0) + 2(0) = 0 which is > -4 since 0 is greater than all negative numbers
Also
-5(0) + 6(0) = 0 which is indeed ≤ 6
So one point is (0, 0)

We have to prove that all circles are similar.
We know that ;
A circle is a geometric shape in which the outside points are all equidistant from a center point.
Let's assume there are two circles and the radius of circle A is a and circle B is b .
If we center the circles on the same point, we found that by multiplying the radius of Circle B which is b by an unknown value x will give the radius of Circle A which is a.
and
The scale factor will be ;
bx = a
or
x = a / b
We know that dilation makes the shape bigger or smaller.
So , we have satisfied the definition of similarity and we can conclude Circle A is similar to Circle B.

Answers
Solving for the least common multiple (LCM), the least numbers of packs you should buy in order to have the same numbers of hot dogs and buns is 4 packs of hotdogs and 5 packs of buns.
A common multiple is defined as a whole number, that is a shared multiple of each set of numbers. The least common multiple (LCM) of two integers is the smallest positive integer that is divisible by both numbers.
If hot dogs come in packs of 10, while buns come in packs of eight, solving for their LCM,
10 : 10, 20, 30, 40, 50, . . .
8 : 8, 16, 24, 32, 40, 48, . . .
LCM = 40
Considering 40 hotdogs and 40 buns, dividing each by 10 and 8, the number of packs of each will be:

The probability will:

How does the probability change?We know that as larger is the size (or the diameter at least) of the hole, the easier will be to lading the skee ball on that hole.
So "If the size of the 40-point hole is enlarged, the probability... "
If you increase the size, then it will be easier to land the ball, thus we can conclude that the probability will increase.
" If the 40-point hole is made smaller, the probability..."
Opposite as the case above, this time will be harder to land the ball, thus the probability will decrease.
"If the 40-point hole stays the same size, but the scoring zone is made smaller, the probability..."
If the ball is thrown in a random way, such that the probability of landing in any region of the scoring zone is the same, then the probability of landing on the 40-point hole is equal to the quotient between the area of the hole and the total area of the scoring zone.
Thus, is you decrease the area of the scoring zone, then the probability increases.
