[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \frac{17}{12}}}}}} [/tex]

Step-by-step explanation:

[tex] \sf{ \frac{7}{12} + \frac{5}{6} }[/tex]

Take the L.C.M of 12 and 6

To find L.C.M , first of all find the prime factors of each numbers.

12 = 2 × 2 × 3

6 = 2 × 3

Take out the common prime factors i.e 2 and 3

Also take out the other remaining prime factors : 2

Multiply those all prime factors and obtain L.C.M

L.C.M = Common factors × Remaining factors

= 2 × 3 × 2

= 12

[tex] \dashrightarrow{ \sf{ \frac{7 + 10}{12}}} [/tex]

Answer:

≈ 33.3 cm²

Step-by-step explanation:

Given the linear ratio of 2 similar cones = a : b , then

ratio of their areas = a² : b²

Here the ratio of radii = 2 : 3 , thus

ratio of areas = 2² : 3² = 4 : 9

let x be the area of the smaller cone then by proportion

[tex]\frac{4}{x}[/tex] = [tex]\frac{9}{75}[/tex] ( cross- multiply )

9x = 300 ( divide both sides by 9 )

x = 33.33333

Thus

surface area of smaller cone ≈ 33.3 cm² ( nearest tenth )

Answer:

Step-by-step explanation:

z - some integer

then the consecutive integer would be:

z+1,  (or z-1)

the sum is 69 so:

z + z+1 = 96

2z = 68

z = 34

z+1 = 34 + 1 = 35

(or:

z + z-1 = 69

2z = 70

z = 35

z-1 = 35 - 1 = 34)

Answer:

  B.  1.2×10^-3 mm

Step-by-step explanation:

What constitutes an "appropriate" unit depends on the use of the number. Since we're not told of any particular use, we might choose the smallest of the available units: mm.

Answer: KJL, LJK and ∠J

Step-by-step explanation:

We have two rays.

JK and JL.

So the common point of bot rays is the point J.

In the angle notation, we usually write the common point in the middle.

So the possible notations for this angle are:

LJK or KJL.

Also knowing that the vertex of the angle is at the point J, we also could call this angle as:

∠J.

So the correct options are B, F and i suppose that the option D is actually ∠J (you wrote that the option D is only J)

Answer:

310

Step-by-step explanation:

What is 310 as a decimal? To write 310 as a decimal you have to divide numerator by the denominator of the fraction. 310 is not a fraction so it is a decimal already.

Answer:

3.1 is a decimal and 310/100 or 310% is the percentage for 310/100.

Answer:

[tex]x = \frac{82}{3}[/tex]

Step-by-step explanation:

[tex](\frac{3}{4} )x = \frac{41}{2}[/tex]

[tex]\frac{3x}{4} = \frac{41}{2}[/tex]

[tex]\frac{3x}{4} * 4 = 4 * \frac{41}{2} \\3x = \frac{41 }{2} * 2 * 2\\3x = 41 *2 \\3x = 82 \\[/tex]

[tex]\frac{3x}{3} = \frac{82}{3}[/tex]

[tex]x = \frac{82}{3}[/tex]

The number is   [tex]\frac{82}{3}[/tex]  .

Fractions , represent a numerical value that expresses a part of a whole. The whole can be any number, a specific value, or a thing. Fractions are represented in the form of p/q. For example, ¼, ½, ¾, and so on.

According to the question

Let the number be x .

If 3/4 of a certain number is equal to 41/2

i.e

[tex]\frac{3}{4}x = \frac{41}{2}[/tex]

x = [tex]\frac{41}{2} *\frac{4}{3}[/tex]

x = [tex]\frac{82}{3}[/tex]

Hence, the number is   [tex]\frac{82}{3}[/tex]  .

Answer:

Probability = [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Length of segment AD = 12 units

Since, AC = CD

Therefore, AC = CD = [tex]\frac{12}{2}[/tex] = 6 units

Since, AB = BC

Therefore, AB = BC = [tex]\frac{1}{2}AC[/tex] = 3 units

Number of total segments = 5

Number of segments having measure greater than three = 3

(AC = CD = 6 units and AD = 12 units)

Probability that the measure of a segment is greater than 3

= [tex]\frac{\text{Number of segments measuring greater than 3}}{\text{Total number of segments}}[/tex]

= [tex]\frac{3}{5}[/tex]

Answer:

-18.9 °F

Step-by-step explanation:

First, find the temperature at noon:

-13 + 6.3

= -6.7

Then, find the temperature at 3pm:

-6.7 + 3.9

= -2.8

Then, find the temperature at 6pm:

-2.8 - 16.1

= -18.9

So, the temperature at 6pm was -18.9 °F

Answer:

A program at a community college can be completed in no fewer than 8 months, but must be completed in less than 11 months.

Step-by-step explanation:

1. The closed dot means the number is equal to and the open dot means the number is less/ greater than

2. The line goes right from the 8 with a closed dot, making x greater than or equal to 8

3. The line goes left from the 11 with an open dot, making x less than ll

4. This means the number must be equal to or greater than 8, and less than 11

The situation that can be represented by the graph is this:

In the number line, numbers 8 to 11 are shaded. This is a range which can mean that the time duration for the completion of a college program cannot be lower that 8 months.

It can also be interpreted to mean that the time span cannot exceed 11 months. Therefore, option C is right.

Answer:-8j^2-16k

Step-by-step explanation:

First step:-2j^2-(-2)k=-2j^2+2k

Second step:

-6(j^2+3k) use the formula a(b+c)=ab + ac

a=-6 b=j^2 c=3k

-6j^2+(-6).3k

-6j^2-6.3k=-6j^2-18k because we multiplied 6x3=18

So we gather the whole equation And simplify

-2j^2+2k-6j^2-18k

-2j^2-6j^2 +2k-18k(add like terms)6+2=8

-8j^2+2k-18K (subtract Like terms 18-2=16)

And the answer will give -8j^2-16k
