0.8x0.09=0.072

80x0.9=72

8x0.9=7.2

Step-by-step explanation:

Answer:

1. = 0.72

2. = 0.072

3. = 72

4. = 7.2

Step-by-step explanation:

8 times 9 is 72. Each answer is some factor of 72. The 1st is one hundredth. The 2nd is one thousandth. The 3rd is just 72. And the last is one tenth.

Answer:

4 1/12

Step-by-step explanation:

Answer:

first of all we will subtract 10 from 6 which is 4 the whole number is 4

second we will subtract 2 from 3 which is 1 so the numerator is 1

third we will multiply 4 with 3 that is 12 so the denominator is 12

The polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.

Like terms should be combined together when adding polynomials.

Let x represent the polynomial expression that would be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n².

Therefore:

–7mn + 2m² + 3n² + x = 5m² + 2mn - 9n².

x = 5m² + 2mn - 9n² - (-7mn + 2m² + 3n²)

x = 5m² + 2mn - 9n² + 7mn - 2m² - 3n²

Combine like terms together.

x = 3m² - 11n² + 9mn

Therefore, the polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.

any perpendicular bisector of one of the sides".

We can define a line of reflection as the line in which a shape is reflected, or we can say that it is the mirror in which the shape is reflected. The line of reflection is the perpendicular bisector of any pair of corresponding points. If you want to join sets of corresponding points on the object and image, then

Answer:

x−2y+5=0

Step-by-step explanation:

x2+y2−2x+4y=15

differentiating both sides with respect to x

2x+2yy′−2+4y′=0

2x−2+(2y+4)y′=0

y′=2−2x2y+4

y′(−1,2)=2+24+4=12

slope of tangent at (- 1, 2)=12

Equation of the tangent is

y−2=12(x+1)

Answer:

Hi there! Your answer here is 11kg - the average of the seven weights is 11kg. To find the average of a group of numbers, you add all of the numbers (12, 12, 12, 12, 12, 12, 5), then divide by the count of those numbers (7).

12 + 12 + 12 + 12 + 12 + 12 + 5 (or 12*6 + 5) is equal to 77.

77 / 7 = 11.

So the average of the seven weights is 11kg.

Answer:

1046

Step-by-step explanation:

formula for arithmetic sequence is:

aₙ = a₁ + (n-1)d

a₁ = first value in sequence

n = term value

d = common difference

a(150) = 3 + (150-1)7

= 3+1043

= 1046

150 is a term in this sequence, its 22nd of the sequence

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n-1)d, ...

Its nth term is

T_n = a + (n-1)d

(for all positive integer values of n)

And thus, the common difference is

T_{n+1} - T_n

for all positive integer values of n

Given;

The arithmetic sequence; 3,10,17,24

D= 10-3=7, a=3

150=3+(n-1)7

150=3+7n-7

150=7n-4

150+4=7n

7n=154

n=154/7

n=22

Therefore, 150 is 22nd term of the sequence.

Answer: Multiplication, subtraction, addition or multiplication, addition, subtraction. It doesn't matter which one you will get the same answer.

Step-by-step explanation:

Answer:

x=24.583

Step-by-step explanation:

first, find a common multiple of both 50 and 6.  I used 150, I turned 2.95 into 73.75. so 73.75/150 reduced into '50s would be 24.583. or you can just say 2.95/6= 24.58/50. you can also use an online calculator if you believe that this is incorrect

well, we know it's centered at (-2 , 1) and it passes through (-4 , 1), if it passes through there, that means that the distance from the center to (-4 , 1) must be its radius.

You can use the law of cosine to find the measure of angle P.

The measure of angle P is given by

Option C : 57°

Let there is triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:

[tex]c^2 = a^2 + b^2 - 2ab\cos(\theta)}[/tex]

(c is opposite side to angle A)

Refer to the attached figure below.

Using the cosine law, we get

|PQ| = a = 17 units, |QR| =length of  opposite side to P = c = 15 units, |PQ| = b = 14 units.

Thus, let angle QPR be of θ degrees, then

[tex]cos(\theta) =\dfrac{a^2 + b^2 - c^2}{2ab} = 0.546\\\\\theta = arccos(0.546) = 56.9^\circ, -56.9^\circ[/tex]

triangle's angles are measured positive, thus, measure of angle P came out as 56.9 degrees or approx 57°

Thus,

The measure of angle P is given by

Option C : 57°
