Answer:
Scale used for drawing is 1 cm = 1.75 m
Step-by-step explanation:
An architect makes a scale drawing of a house.
Actual width of porch = 7 meters
Width of porch on drawing = 4 cm
So, Actual width = Drawing width
So, 4 cm = 7 m
1 cm = 1.75 m
So, Scale: 1 cm = 1.75 m
So, Option B is correct
B)1 cm = 1.75 m
Hence scale used for drawing is 1 cm = 1.75 m
Lines v and t are parallel, and are cut by transversals m and h. What is the degree measure of angle y? I need an answer fast.
y = _____ degrees
Answer:
y = 123 degree
Step-by-step explanation:
180 - 57-60 = 63
The lines v and t are parallel that v shows us 180-60-57 = 63
The lines t shows us 63 + 60 = 123 degree
The angles can also be solved just 180-57 = 123 but wouldn't prove the comparison of v and t and how mv angle is larger than mh..

The second of three numbers is 8 more than the first,
and the third number is 3 less than 3 times the first.
If the third number is 15 more than the second, find
the three numbers.
Answer: The numbers in order are 13, 21, 36
Step-by-step explanation:
First of all, we must convert all the information given in the question into equations so we can look it from a simplified angle, and hence, solve it.
So, let's start off by giving each of the unknown numbers a name. Let's call the first number a, the second number b, and the third number c.
Therefore:
"The second of three numbers is 8 more than the first" gives us:
b = 8 + a
"... the third is 3 less than 3 times the first" gives us:
c = 3a - 3
and "the third number is 15 more than the second" gives us:
c = 15 + b
Now, we can substitute b = 8 + a into c = 15 + b, to get:
c = 15 + (8 + a), which simplified gives us:
c = 23 + a
With that done we can use elimination.
We've got c = 23 + a, and c = 3a - 3. We want to eliminate 'a', so we should multiply both sides of c = 23 + a by (-3) to get: -3c = -69 - 3a.
Now we can eliminate the 'a' variable:
c = 3a - 3
-3c = -3a - 69
-------------
-2c = -72
Therefore, we can solve for 'c' by dividing both sides by -2, which leaves us with:
c = 36
Now we can plug that value of 'c' into the equation c = 15 + b, to solve for b:
36 = 15 + b (Subtract 15 from both sides)
21 = b
Now that we've got a value for 'b', we can plug it into the equation b = 8 + a to solve for 'a':
21 = 8 + a (Subtract 8 from both sides)
13 = a
Sorry it's very long, but it's how I solved this
Hope this helped! ;)

John has a bag of red and blue marbles. John chooses 2 marbles without replacing the first. Let A be the event where the first marble chosen
is red. Let B be the event where the second marble chosen is blue.
The conditional probability of an event depends on the occurrence of another event. The correct option is C.
What is Bayes' Theorem?The conditional probability of an event depending on the occurrence of another event is equal to the likelihood of the second event given the first event multiplied by the probability of the first event, according to Bayes' Theorem.
Suppose that there are two events A and B. Then suppose the conditional probability is:
P(A|B) = probability of occurrence of A given B has already occurred.
P(B|A) = probability of occurrence of B given A has already occurred.
Then, according to Bayes' theorem, we have:
[tex]\rm P(A|B) = \dfrac{P(B|A)P(A)}{P(B)}[/tex]
(assuming the P(B) is not 0)
Given John has a bag of red and blue marbles. John chooses 2 marbles without replacing the first. Let A be the event where the first marble chosen
is red. Let B be the event where the second marble chosen is blue. Therefore, the Probability P(B|A)=0.6 is described as the probability of choosing a blue marble after a red marble has been removed is 0.6.
Hence, the correct option is C.

What is the perimeter of the object (Hint: Not all numbers should be used to find your answer) (Provide number only in your answer) *
Answer:
27 IN
Step-by-step explanation:
If you want to calculate the perimeter of an irregular trapezoid, there's no special formula - just add all four sides:
Trapezoid perimeter = a + b + c + d
Maybe you've noticed, but it's the formula for any quadrilateral perimeter.
There's also an option that that presents itself with certain special trapezoids - like an isosceles trapezoid, where you need a, b, and c sides. Another example is a right trapezoid, where the length of the bases and one leg are enough to find the shape's perimeter (the last leg is calculated using Pythagoras' Theorem).

how long must diagonal AC be so angle B is a right angle?
uprgigt corner is D other side is C
Downleft is A across from B
16 ft down and 12 ft side
Answer:
BxA=F
Step-by-step explanation:
Diagonal AC must be 20 feet so that ∠B will be 90°.
According to asked question, buck is creating a horse coral by designing in such a way that corners will be at 90°.
So according to question we have to make ∠B as 90°.
So quadrilateral ABCD becomes a rectangular.
Therefore ΔABC will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.
What is Pythagoras Theorem?The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.
In the right-angle tringle ΔABC,
AC²=AB²+BC²
⇒ AC²=16²+12²
⇒ AC²=256+144=400
⇒AC=√400
⇒AC=20 feet
Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.

Tannis's first machine could throw a car 27 meters. She studied her first machine and built a better one. Her second machine could throw a car 7 times as far.
How far does the second machine throw a car?
Answer:
Hello! Your answer would be 189 meters.
Step-by-step explanation:
First, let's examine the problem closely. It says that Tannis's first machine could throw a car 27 meters, but then she studied her first machine and built another one. So far we have one part of the problem that will get us to our solution, 27 meters. The next part is where we get our last two parts of our problem, the operation and the other factor. The second part of this problem says that Tannis's second machine could throw a car 7 times as far, meaning her second machine could throw a car 7 times farther then her first machine. We are given our operation, multiplication, first, and our second factor, 7, last. Then, we must look closely at the main question we are trying to answer: How far does the second machine throw a car? We can form and evaluate an expression to answer this question. With the information we've gathered, we can form the expression: 27 meters x 7, and that equals 189 meters. I hope this helps and make sure you have an amazing day!
The distance travelled by the second machine is 189 meters.
What is mathematical operations?
The mathematical “operation” refers to calculating a value using operands and a math operator.
What will be the distance travelled by second machine?According to question, Tannis's initial machine could toss a car 27 meters, but after studying it, she constructed a new one.
We currently just have the 27 meters portion of the problem, which will lead us to the answer.
The second portion of the equation states that Tannis's second machine could toss a car seven times farther than her first machine, or seven times as far.
Our operation, multiplication, comes first, followed by our second factor, 7, in that order. With the knowledge we have acquired, we may formulate the formula: 27 meters times 7 = 189 meters.
Therefore, the correct answer is 189 meters.
