Find the distance between A(-1, -1) and B(4, -5). Round your answer to the nearest tenth.
Answer:
6.4 units (nearest tenth)
Step-by-step explanation:
Distance between 2 points
[tex] = \sqrt{(y1 - y2)^{2} + (x1 - x2)^{2} } [/tex]
Distance between A and B
[tex] = \sqrt{[ - 1 - ( - 5)]^{2} + ( - 1 - 4)^{2} } [/tex]
[tex] = \sqrt{( - 1 + 5)^{2} + ( - 1 - 4) {}^{2} } [/tex]

Answer:
Similar by SAS
Step-by-step explanation:
If you multiply the two given sides by 3/2 you will get the sides for the large triangle
3/2 * 10 = 30 / 2 = 15
3/2 * 24 = 72 / 2 = 36
Therefore they are similar by SAS postulate for similarity. Notice that the right angle is between the legs of the triangle. That is the main qualification that allows you to use SAS for similarity.
Find the other two angles of both the triangles, if they were similar then the triangles are similar
12. If I || m, find the value of x.
(9x - 4)+3 (5x + 16)
I know that X=12
But I need help showing my work
Answer:
x = 12
Step-by-step explanation:
(9x - 4)° + ( 5x + 16 )° = 180°
9x + 5x - 4 + 16 = 180
14x + 12 = 180
14x = 180 - 12
14x = 168
x = 12

Lucas and Tony were trying to solve the equation: x^2=16x+25 Lucas said, "The x^2, squared term is isolated, so I"ll take the square root of both sides and solve." Tony said, "I'll solve using the quadratic formula with a=1,b=16, an c equals 25." Whose solution strategy would work? Choose 1 answer:
Answer:
Tony's solution strategy
Step-by-step explanation:
Given the equation that Lucas and Tony trying to solve expressed as: x^2=16x+25
This can be written in standard form as x^2 - 16x - 25 = 0
This can then be factorized using the general formula
x = -b±√b²-4ac/2a where a, b and c are constants
From the given expression;
a = 1, b = -16, c = -15
Hence the best strategy that would have worked based on the explanation is Tony's

A man received a monthly salary of $3500 together with a commission of 5% on all sales over $5000 per month. Calculate his gross salary in a month in which his sales amounted to $40,000.
Answer:
$5500
Step-by-step explanation:
3500 + 0.05 * 40,000 = 5500
His gross salary in a month in which his sales amounted to $40,000 would be; 5500 dollars.
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
It is given that man received a monthly salary of $3500 together with a commission of 5% on all sales over $5000 per month.
Let the x represents his gross salary in a month in which his sales amounted to $40,000.
Therefore,
x = 3500 + 0.05 (40,000)
x = 3500 + 2000
x = 5500
Hence, his gross salary in a month in which his sales amounted to $40,000 would be; 5500 dollars.

An oil-drilling rig has dug a hole to a depth of -60 ft. after one full day and night of continuous
use. The rate of the rig stayed constant over that time.
Part A: The rig will be used to dig a second hole with a depth of -150 ft at the same rate as
before. How many hours will the rig take to complete digging the hole?
Answer:
It will take 60 hrs
Hope this helped!
Answer:
It would take 60 hours for the rig to complete digging the -150 ft. hole.
Step-by-step explanation:
Hint: Using ratios will help solve questions like this one.
The first hole was dug -60 ft. below the surface for a whole day and night. A day lasts 12 hours and the same goes for a whole night. That's 24 hours in total. This will help answer Part A. A second hole was dug -150 ft. below the surface with the same rate as the first hole. Let's put this into a ratio.
-60 : 24
-150 : ?
Finding the scale factor in ratios will help solve for the missing value. We can divide -150 by -60 which results in 2.5. Multiply 2.5 by 24 and you will get 60 hours as your final answer. I hope you will find this helpful! :D

Answer:
Step-by-step explanation:
Answer:
A1. The answer is option (b) 1/10
A2. The answer is option (b) 13.4 cm²
A3. Shaded area not provided
A4. The answer is option (b) Unlike Fractions
A5. The answer is option (d) 20
A6. The answer is option (b) 21/23
A7. The answer is option (c) 5/27
Step-by-step explanation:
A1. We multiply the denominators (the numbers on the bottom) and the numerators (the numbers on top) to multiple fractions. As a result, for (1/2) x (1/5), we have
(1/2) × (1/5) = (1 × 1) / (2 × 5) = 1/10.
A2. Multiplying the length by the breadth yields the area of a rectangle. The dimensions in this instance are 6.7 cm in length and 2 cm in width. So, the area may be determined as follows:
Area = length × breadth = 6.7 cm × 2 cm = 13.4 cm².
Hence, the correct answer is (b) 13.4 cm².
A3. Please provide the shaded area.
A4. Fractions that have different denominator are called unlike fractions.
So the answer is option (b)
A5.Let us suppose India played 'x' number of matches
According to the Question, India won 3/5 of its matches, which implies that they won 3/5 * x matches.
It is also mentioned that India won 4 more matches than it lost against New Zealand. Therefore, the number of matches India won against New Zealand is 4 more than the number of matches it lost against New Zealand.
From this, we can set up the equation:
3/5 * x = (x/2) + 4
Multiplying both the sides by 10, we have
6x = 5x + 20
subtracting 5x from both sides:
6x - 5x = 5x - 5x + 20
x = 20
Hence, India played 20 matches.
A6. When the numerator is less than the denominator, the fraction is said to be proper fraction. Hence among the given options, 21/23 fits the best.
Hence option (b) is correct
A7. To find what should be added to 21/27 to make it 26/27, we need to calculate the difference between the two fractions.
Let us suppose that we need to add x
=> 21/27 + x = 26/27
=> x= 26/27 - 21/27 = 5/27
Therefore, the answer is (c) 5/27.

Answer:
23
Step-by-step explanation:
234Suppose you have a bag with 50 letter tiles in it and 23 of the tiles are the letter Y. If
23
you pick a letter tile at random from the bag, the probability that it is the letter Y is Suppose
50
another bag has 200 letter tiles in it and 172 of the tiles are the letter Y. Write the probability of
picking a tile that is the letter Y as a fraction and as a percent. From which bag are you more likely
to pick a tile that is the letter Y?
The probability of picking the letter Y from bag of 50 letters is 23/50 or 0.46 or 46% and probability of picking the letter Y form bag of 200 letters is 172/200 or 0.86 or 86%. as the probability of getting the letter Y is more in second bag this it is better to pick the bag containing 200 letters.
What is a probability?The probability explains the chances of happening a event. The probability of an event is a number between 0 and 1, where, 0 indicates impossibility of the event to happen and 1 indicates certainty of the event to happen.
From the question it is said that a bag of 50 letter contain 23 Y letters. Thus the probability of the letter Y picking is 23/50 i.e, number of times the letter Y can come out if we pick the letters 50 times. So, it is certain that 23 Y letters can come out.
23/50= 0.46 or 46%
And if the bag contain 200 letters in which 172 are Y letters then the probability to pick Y is 172/200
172/100 =0.86 or 86%
As the chance to get Y letter is mor in bag containing 200 letters thus pick this bag.
thus the 1st bag probability is 46% and for 2nd bag is 86%. Hence choose 2nd bag
