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:

hypotenuse = 8[tex]\sqrt{3}[/tex] , leg = 12

Step-by-step explanation:

Using the cosine and tangent ratios in the right triangle and the exact values

cos60° = [tex]\frac{1}{2}[/tex] , tan60° = [tex]\sqrt{3}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{3} }{hypotenuse}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

hypotenuse = 4[tex]\sqrt{2}[/tex] × 2 = 8[tex]\sqrt{2}[/tex]

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

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opposite}{4\sqrt{3} }[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by 4[tex]\sqrt{3}[/tex] )

opposite = 4[tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] = 12

Answer:

Lengths are 8√3 and 12

Step-by-step explanation:

» From trigonometric ratios, using our angle as 60°

[tex]{ \tt \cos( \theta) = \frac{adjacent}{hypotenuse} } \\ \\ { \tt{ \cos( 60 \degree) = \frac{4 \sqrt{3} }{hypotenuse} }} \\ \\ { \tt{hypotenuse = \frac{4 \sqrt{3} }{ \cos(60 \degree) } }} \\ \\ { \tt{hypotenuse = \frac{4 \sqrt{3} }{0.5} }} \\ \\ { \boxed{ \tt{hypotenuse = 8 \sqrt{3} }}}[/tex]

» Using 30° as our angle:

[tex]{ \tt{ \tan( \theta) = \frac{opposite}{adjacent} }} \\ \\ { \tt{ \tan(30 \degree) = \frac{4 \sqrt{3} }{adjacent} }} \\ \\ { \tt{adjacent = \frac{4 \sqrt{3} }{ \frac{1}{ \sqrt{3} } } }} \\ \\ { \tt{adjacent = \frac{(4 \sqrt{3} ) \times ( \sqrt{3}) }{1} }} \\ \\ { \tt{adjacent = 12}}[/tex]

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

Step-by-step explanation:

Answer:

3x

Step-by-step explanation:

a = 4x - 4

The perimeter is equal to 14x + 8 but it is also equal to 2a + 2b, so

14x + 8 = 2(4x - 4) + 2b

14x + 8 = 8x - 8 + 2b

Let's move 2b to the other side of the equation, we get:

14x + 8 - 2b = 8x - 8

Now, let's move 14x + 8 to the other side too to find what -2b is equal to

-2b = 8x - 14x + 8 - 8

Gonna simplify:

-2b = -6x

Now, let's multiply both sides with -1 to find what 2b is equal to

-2b * -1 = -6x * -1

2b = 6x

Now, we know that 2*b is equal to 6x, but we need to find what side b is equal to, so we gonna divide 6x by two to get what b is equal to

2b = 6x

b = 3x

Side b is equal to 3x

Answer:

So for instance in basic math you might say 3 times 4 right this means 3 times 4 is equal to 12 obviously. But you see the X here in algebra is going to look like a variable.

Hence, 5/6% of 300 is 2 1/2.

The percent of 300 is 83.33%.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Given

300 is 2+1/2 is an expression

The percentage of a given function.

Let x be the percent of 300.

300 is 2+1/2 is an expression that can be written as,

Step-by-step explanation:

Using correlation coefficients, it is found that the -0.63 correlation between number of absences and final exam score means that there is a strong negative correlation between number of absences and final exam score.

It is an index that measures correlation between two variables, assuming values between -1 and 1.

If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.

If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

In this problem, the correlation is of -0.63, hence:

It means that that there is a strong negative correlation between number of absences and final exam score.

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

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.
