Answer:
The ladder is 28.6 feet long.
Step-by-step explanation:
Given that:
Length of base = 17 feet
Length above the ground = 23 feet
These forms two legs of right angled triangle.
The length of ladder will be the hypotenuse.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(17)^2 + (23)^2 = c^2 \\289 + 529 = c^2 \\c^2 = 818[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{818}\\c=28.6[/tex]
Hence,
The ladder is 28.6 feet long.
someone please do this and explain in detail of how you get x.
Answer:
x=8
AC=148
Step-by-step explanation:
Okay so if B is the midpoint of AC, that basically means that it's the halfway point. If B is exactly halfway between A and C, that means that the distance between A and B, and the distance between B and C is the same. In other words: AB=BC
Knowing that AB=BC, we can sub the values given by the question:
AB = BC
9x+2 = 5x+34
9x-5x = 34-2
4x = 32
x = 8
Now that we know the value of x, we can find AC, since AC=AB+BC
AC = AB + BC
= 9x+2 + 5x+34
= 14x+36
= 14(8)+36
=112+36
=148

The total cost of 3 bags of chips and 4 jars of salsa at a
store is $11.25. The cost of each bag of chips is $2.75.
Write an equation that can be used to determine the cost
,
X, of 1 jar of salsa.
Answer: 2.75(3) + 4x = 11.25
Step-by-step explanation:
It says each bag costs $2.75 and there are 3 bags so multiply those 2 and then subtract them from the total cost (11). What you get after you subtract is the total costs of the salsa so divide that by 4 to get the cost of each, in this case it doesn't ask so we leave it as 4x.
the average motorcycle weighs 32,000 grams. How many kilograms does the average motorcycle weigh?
Answer:

In the figure attached, ABC is a right angle triangle.
Sides of this triangle are AB = 12 BC = 5 and CA = 13
Angle opposite to the side having length = 12 is θ.
Now we have to calculate sin θ.
Since Sinθ =

A state Motor Vehicle Department requires learners to pass a written test on the motor vehicle laws of the state. The exam consists of twenty true-or-false questions, of which eighteen must be answered correctly to qualify for a permit. In how many different ways can a learner who answers all the questions on the exam qualify for a permit
Answer:
211 ways
Step-by-step explanation:
Given :
Number of questions = 20
Number of correct correct questions to be answered in other to qualify should be atleast 18
Hence,
Correct questions could be either 18, 19 or 20 ;
Using combination :
nCr = n! ÷ (n-r)!r!
20C18 = 20! / (20 - 18)!18!
20C18 = (20* 19) / (2 * 1) = 190 ways
20C19 = 20! / (20-19)!19!
20C19 = 20 / 1 = 20 ways
20C20 = 20! / 0! 20! = 1 ways
Hence, total number of possible ways = (190 + 20 + 1) = 211 ways
if x is the first of two consecutive integers, express the sum of the two integers in terms of x
Answer:
2x+1
Step-by-step explanation:
x = 1st integer
x+1 = next consecutive integer
The sum is
x+ (x+1)
Combine like terms
2x+1
let the first integer be x and the second be x + 2
then the sum is x +x+2 = 2x +2

The stock market dropped 220 points on Monday. It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points. What was the amount of change over those three days.
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220 would be 48.
The amount of change over those three days is 268 points.
Here,
The stock market dropped 220 points on Monday.
It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points.
We have to find, the amount of change over those three days.
What is amount?
The sum total of two or more quantities or sums, is called amount.
Now,
The stock market dropped 220 points on Monday.
It lost another 48 points on Tuesday.
Hence, the points after loss = 220 - 48 = 172
And, when it gained 96 points.
Then, the points after gain = 172 + 96 = 268
Hence, The amount of change over those three days is 268 points.

Find the value of x if A, B, and C are collinear points and B is between A and C. AB=6x,BC=x−5,AC=23
Answer:
The value of x = 4 if A, B, and C are collinear points and B is between A and C.
Step-by-step explanation:
We need to find the value of x if A, B, and C are collinear points and B is between A and C.
We have AB=6x,BC=x−5,AC=23
If points are collinear and B is between A and C we can write:
AC=AB+BC
Putting values and finding value of x
[tex]AC = AB+BC\\23=6x+x-5\\23=7x-5\\7x=23+5\\7x=28\\x=\frac{28}{7}\\x=4[/tex]
The value of x = 4 if A, B, and C are collinear points and B is between A and C.
