Answer:

Step-by-step explanation:

The commonly used symbols for ratios are a colon or a fraction bar. Words can also be used.

  6 : 7 = 6/7 = 6 to 7

__

When the ratio is part of a proportion, then it might be written ...

  6 is to 7

as in ...

  6 : 7 :: 12 : 14 . . . . . . . 6 is to 7 as 12 is to 14

Answer: Add two circles to the left and a square to the right

Step-by-step explanation:

Answer:

k = 0.25t^2

Step-by-step explanation:

Given the equation :

b = 0.25t

b = number of inches that has burned away

t = time

From our knowledge of variation;

Since candle length will decrease with time ;

b α 1/ t

b = k/t

Where k is the proportionality constant

Comparing the equation :

b = 0.25t

k/t = 0.25t

k = 0.25t^2

Answer: the answer is going to be 9

Answer:

9.4 rounded to the nearest 10th - 9

Step-by-step explanation:

If the tenth in the decimal is 4 or lower, (like 9.4 or 9.3) It would round down to 9, but if it were 5 or higher like (9.5) it would be 10.00 or 10 :)

Answer:

27 :)

Step-by-step explanation:

Answer:

27!

Step-by-step explanation:

As we know that

So , we need to find side of square first

Using area of square = Side²

➩ 144 = S²

➩ S = √144

➩ Side = 12 cm

Now ,

➨ Diagonal = √2 ( 12 )

➨ Diagonal of square = 12√2

Given:

Consider the expression is [tex]\sqrt{-12}[/tex].

To find:

The value of given expression.

Solution:

We have,

[tex]\sqrt{-12}[/tex]

It can be written as

[tex]\sqrt{-12}=\sqrt{-1\times 12}[/tex]

[tex]\sqrt{-12}=\sqrt{-1}\times \sqrt{12}[/tex]      [tex][\because \sqrt{ab}=\sqrt{a}\sqrt{b}][/tex]

[tex]\sqrt{-12}=i\times \sqrt{12}[/tex]      [tex][\because \sqrt{-1}=i][/tex]

[tex]\sqrt{-12}=\sqrt{12}i[/tex]

Therefore, the value of given expression is [tex]\sqrt{12}i[/tex].

Note: all options are incorrect.

c. 17/2

Step-by-step explanation:

y(1/2 + z) + 6

2 (1/2 + 3/4) + 6

1 + 6/4 + 6

find common denominator

4/4 + 6/4 + 24/4 = 34/4 reduced to 17/2

Answer:

A. Juan wins the race

B. At about 7 minutes J(t )= A(t)

C. 2 minutes

Step-by-step explanation:

A. Juan wins the race. This is because she covers the distance in a shorter time interval than Antonio

B. At about 7 minutes J(t )= A(t). to get this, just look at the point that the two curves intersect on the graph, and trace it down to the time axis to read off the time.

C. J(t) is greater than A(t) with about 2 minutes. To get this, we just subtract the time Juan arrived at the finish line from the time Antonio arrived, this is = 15 -13 = 2 minutes

Answer:

<C =10°

Step-by-step explanation:

The sum of angles in a triangle is 180°. Hence,

<C+<D+<E =180

Given

<C =x-4

<D = 11x-11

<E = x+13

Substitute

x-4+11x-11+x+13 = 180

13x-2 = 180

13x =180+2

13x = 182

x = 182/13

x = 14

Get <C

Since <C = x-4

<C = 14-4

<C =10°

Answer: <C =10°

Answer:

6x2−3x−20

Step-by-step explanation:

Let's simplify step-by-step.

x2+5x2−3x−20

=x2+5x2+−3x+−20

Combine Like Terms:

=x2+5x2+−3x+−20

=(x2+5x2)+(−3x)+(−20)

=6x2+−3x+−20

Answer:

Inequality: 8x+194_>598

Answer:x_>50.2

Step-by-step explanation:

I have delta math! I risked getting the answer wrong for this question lol. But this is correct just!

404 spoons are required for the restaurant for the fill needs.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Let's say the number of sets required = x

Then,

8x will be the total number of spoons.

So,

8x + 194 ≥ 598

8x ≥ 404

x ≥ 50.5

A number of spoon required = 50.5 × 8 = 404 spoons.

Hence "404 spoons are required for the restaurant for the fill needs".

#SPJ2

We know that 15 elves represent the 20% of the total.

Since 20% is one-fifth, the total number of elves is

[tex]15\cdot 5 = 75[/tex]

Alternatively, solve the proportion

[tex]15\div x = 20\div 100[/tex]

which yields

[tex]x=\dfrac{1500}{20}=75[/tex]

im not sure if this is the answer you wanted hope it helped though

Step-by-step explanation:

Applying the BODMAS rule where B=Brackets ,O=of,D=Division,M=multiplication,

A=Addition,S =subtraction

For any equation in which multiple operation is to be done its depends on the preference of the operation to be performed.

The preference followed is BODMAS

In the above question first multiplication will be performed first and then the addition is performed.

10+10*0+10

10+0+10

Answer is 20

Answer:

D. a car goes 7 feet and then reversed 7 feet.

Step-by-step explanation:

The statement above can be set up in a simple equation.

7 - 7 = 0

This can best represent the equation 10 + (-10) = 0, because they both end up with the same result.

10 + (-10) = 10 - 10 = 0
