PLEASE HELP. !!!!!!!!!!

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]

[tex] = \sqrt{ {4}^{2} + ( - 5) {}^{2} } [/tex]

[tex] = \sqrt{41} [/tex]

= 6.4 units (nearest tenth)

Answer:

La cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.

Step-by-step explanation:

Para responder la pregunta, se debe descomponer el número en cuestión:

87.684

8 = Indica la cantidad de decenas del número, es decir, 8 decenas (80).

7 = Indica las unidades dentro de la decena, es decir, 7 unidades más que 80.

.6 = Indica la cantidad de decenas del entero.

.08 = Indica la cantidad de centésimas del entero.

.004 = Indica la cantidad de milésimas del entero.

Así, la cifra de las decimas es 6, la cifra de las centésimas es 8, la cifra de las milésimas es 4, y en la parte entera, la cifra de unidades es 7, mientras que la cifra de la decena es 8.

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

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.

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.

Answer:

AB = 19.05

∠A = 45°

∠C = 45°

Step-by-step explanation:

To find a missing side length, Use Pythagorean Theorem

Pythagorean Theorem:  [tex]a^{2} +b^2=c^2[/tex]

Then fill in the dimensions given in the triangle

In this case, we're looking for b^2 so...

[tex]11^2+b^2=22^2[/tex]

[tex]121+b^2=484[/tex]

[tex]b^2=484-121[/tex]

b^2 = 363

[tex]\sqrt{363} =19.05[/tex]

so the answer is approximately 19

Now in this case we already know the measure of B by the 90° angle.

so if the total is 180, then 180 - 90 = 90 then divided by 2 for the 2 missing angles = 45°

so the answer is 45°

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.

12x-15+15=6-3x+15 (add fifteen, addition property of equality)

12x=6-3x+15

12x=21-3x (combine like terms)

12x+3x=21-3x+3x (add 3x, addition property of equality)

15x=21 (combine like terms)

15x/15=21/15 (divide by 15, division property of equality)

Answer:

It just makes doing things (like adding and subtracting other numbers) easier if the denominator is a real number. Other than that we just do it out of tradition

This step is done to make the denominator go from a complex number in the form a+bi into a purely real number in the form a^2+b^2 (where 'a' and b are any real numbers).

This is because multiplying a+bi with its conjugate a-bi leads to the following steps

(a+bi)(a-bi)

(a)^2 - (bi)^2 ... difference of squares

a^2 - b^2*i^2

a^2 - b^2*(-1) .... recall that i^2 = -1

a^2 + b^2

----------------

So for example, if your denominator was 2+3i, then you'd multiply that by the conjugate 2-3i and you'd end up with the final denominator of 2^2+3^2 = 4+9 = 13. In this case, a = 2 and b = 3.

Note: make sure to multiply both top and bottom by a-bi (not just the denominator).

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

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.

Answer:

80/121

Step-by-step explanation:

For simplicity,

Probabilities of getting a red, a blue or a green in a single spin are, respectively, 4/11, 4/11 & 3/11.

Therefore, probabilities of getting 2 reds, 2 blues or 2 greens in 2 spins are, 16/121, 16/121 & 9/121 respectively.

Then, total probability of getting same colour both times would be 16/121 + 16/121 + 9/121 = 41/121.

Any other option would result in 2 different colours. Thus, the probability of getting two different colours in 2 spins = 1 - 41/121 = 80/121.
