The least common denominator is  12

=======================================================

Explanation:

Your teacher wants you to list the multiples of each denominator.

The values in bold are what will go in the boxes in those first two rows.

The least common denominator is 12 because it is the smallest thing found in common in the two lists above. In other words, 12 is the LCM (least common multiple) of 3 and 4. Note how 3*4 = 12. This works because 3 and 4 do not have any common factors between them other than 1.

The LCD (least common denominator) is the LCM of the denominators. The LCD is useful for when you want to add or subtract fractions. The denominators must be the same for you be able to add or subtract them.

What is ratio and proportion?

Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.

Let the total no. of students in a class be x

then no. of boys in the class be 4x/7

 no.of girls in the class be 3x/7

left handed boys =30%of 4x/7

                              = 3/10x 4x/7

                               =6x/35

Therefore, 6/35 fraction of people in the class are left handed

Answer:

D

Step-by-step explanation:

Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle. Therefore, option D is the correct answer.

An acute angle is an angle that is less than 90°, and these angles can be measured using a protractor.

Triangles can be classified on the basis of angles and sides. An acute triangle is one that is classified on the basis of the measurement of angles. If all the interior angles of a triangle are less than 90°, then the triangle is said to be an acute triangle.

In equilateral triangle all three angles are equal, that is 60°.

Therefore, option D is the correct answer.

Answer:

A. -9, 21

Step-by-step explanation:

Use m.a.t.h.w.a.y and you will get the answer!

Answer:

A

Step-by-step explanation:

| x-6| = 15 , check if this is true for the given x values

for x= -9 we have | -9-6| =  15 true

for x= 21 we have | 21 -6| = 15 true

so A is a solution set

for x= -15 we have | -15-6| =  15 false

so B is not a solution set

for x= 9 we have | 9-6| =  15 false

so C is not a solution set

for x= -9 we have | -9-6| =  15 true

for x= -21 we have | -21-6| =  15 false

so D is not a solution set

for x= -6 we have | -6-6| =  15 false

so E is not a solution set

Answer:

8 x 1/6

Step-by-step explanation:

2 x 4/6 as a multiplication of a whole number and a unit fraction.

First off lets find 2 x 4/6

2 x 4/6 = 8 /6

Ok, now lets go back to the original equation.

2 x 4/6

divide 4/6 by 4 to get a unit fraction

A x 1/6

Divide 8/6 by 1/6 = 8

Or you can do A (previously known as 2) by 4 because we divide 4/6 by 4

A = 2x4 = 8

8 x 1/6 = 8/6

Correct

Answer:

Answer: about 14

Work Shown:

Add up the values in the table:

170+135+150+145 = 600

There are 600 orders in total. Of those 600, we have 135+145 = 280 that are for lemonade or for orange juice. This means roughly 280/600 = 0.4667 of all the drinks are either lemonade or orange juice.

Assuming this ratio keeps up, we can multiply 0.4667 with 30 to get

30*0.4667 = 14.001 which rounds to 14

This represents the estimated number of drinks in the next 30 orders that are either lemonade or orange juice.

The volume of the square pyramid is 600cm^3

Answer:

its 12

2×72=x^2

Step-by-step explanation:

i will sent the Formula in picture

===================================================

Explanation:

f(x) = x^3 - 2x + 3

f ' (x) = 3x^2 - 2 ..... apply the power rule

f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point

f ' (1) = 1

If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value.

Now apply point slope form to find the equation of the tangent line

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

y = x - 1 + 2

y = x + 1   is the equation of the tangent line.

The graph is shown below. I used GeoGebra to make the graph.

Answer:

C. 2, 808 cm^3

Step-by-step explanation:

Given that

The base of the pyramid is 18 centimeters

And, the height of the pyramid is 26 centimeters

We need to find out the volume of the pyramid

As we know that

The volume of the pyramid is

= 1 ÷ 3 × base^2 × height

= 1 ÷3 × 18^2 × 26

= 2,808 centimeter^3

Hence, the correct option is c.

Answer:

1274.7 cubic meters

Step-by-step explanation:

Because the equation to find volume of a cone is V = πr²(h/3), you would have to plug in your values which are h = 5.2m, and r = 15.3m. Once you do the math you will get 1274.72 cubic meters, or 1274.7 when rounded to the nearest tenth.

Answer:

13

Step-by-step explanation:

you have to use Pythagorean Theorem which is

(a^2) + (b^2) = (c^2)

where a and be are the legs 45° from each other and c is the hypotenuse.

so just plug in the numbers

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

now square root both sides to get rid of the square on c

root(169) = root(c^2)

13 = c
