what are all of the ratios that are equivalent to 1/2

Answer:

A

Step-by-step explanation:

i just took the lab assessment

Answer:

The correct option is (c).

Step-by-step explanation:

The combined formula is given by :

[tex]h=\dfrac{V}{\pi r^2}[/tex] ...(1)

h is height

V is volume

r is radius

It is clear from formula (1) that h varies directly with V and inverse;y with the square of r.

Hence, the correct option is (c).

Answer:

h varies directly with V and inversely with the square of r.

Answer:

3/2

Step-by-step explanation:

18 red buttons: 12 blue buttons

18/12

Divide the top and bottom by 6

18/6 = 3

12/6 = 2

3/2

Answer:

3/2

Step-by-step explanation:

18/12 can be broke down and easily simplified given the numbers are even.

18 divided by 2 = 9

12 divided by 2 = 6

9/6

18 divided by 3 = 6

12 divided by 3 = 4

6/4

Simplest form;

18 divided by 6 = 3

12 divided by 6 = 2

3/2

Answer:

[tex]\dfrac{1}{3}(b-21)[/tex]

Step-by-step explanation:

We need to find an equivalent expression for [tex]\dfrac{1}{3}b-7[/tex]

The denominator of first fraction is 3 and that of other is 1.

[tex]\dfrac{1}{3}b-7\\\\=\dfrac{b-21}{3}[/tex]

or

[tex]=\dfrac{1}{3}(b-21)[/tex]

Hence, the equivalent expression is [tex]\dfrac{1}{3}(b-21)[/tex].

The answer Is 1/3(b-21)

Step-by-step explanation:

Answer:

2) given

3) common side

4)angleuwx = angleuwv. ( right angles triangle )

5) angle x = angle y(side angle of isoceles triangle are equal)

Step-by-step explanation:

length of small block =10cm then volume=1000 there are 8 smaller block so volume =8× 1000=8000

so length of bigger block= cube root 8000...

Answer:

[tex]64a^{3} b^{6}[/tex]

Step-by-step explanation:

1) Distribute the exponent outside of the parentheses to the terms inside the parentheses. In this case, multiply the 3 outside the parentheses with the exponent of each of the terms inside:

[tex](4ab^{2} )^3[/tex]

[tex]4^{3}[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]

2) The variables are fine - you can't simplify them further. All you need to do now is multiply the [tex]4^{3}[/tex] out. Remember that it's kind of like asking, "what is 4 × 4 ×4?"

[tex]4[/tex] · [tex]4[/tex] · [tex]4[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]

[tex]16[/tex] · [tex]4[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]

[tex]64a^{3} b^{6}[/tex]

Therefore, [tex]64a^{3} b^{6}[/tex] is the answer.

Answer:

ln([tex]x^{9}[/tex] * [tex]y^{8}[/tex])

Step-by-step explanation:

property:  ln( A * B ) =  ln(A) + ln(B)  :)

ln([tex]x^{9}[/tex]) + ln([tex]y^{8}[/tex])

property:  ln([tex]A^{x}[/tex]) = xln(A)

9*ln(x) + 8*ln(y)   ;)

Answer:

a. 2

Step-by-step explanation:

Area of a square is calculated as:

[tex]Area = Length * Length[/tex]

And the perimeter is

[tex]Perimeter = 4 * Length[/tex]

For (a):

[tex]Length = 2[/tex]

[tex]Area = 2 * 2 = 4[/tex]

[tex]Perimeter = 4 * 2 = 8[/tex]

For(b):

[tex]Length = 4[/tex]

[tex]Area = 4 * 4 = 16[/tex]

[tex]Perimeter = 4 * 4 = 16[/tex]

For (c):

[tex]Length=7.5[/tex]

[tex]Area = 7.5 * 7.5-56.25[/tex]

[tex]Perimeter = 4 * 7.5 = 30,[/tex]

For (d):

[tex]Length = 10[/tex]

[tex]Area = 10 * 10 = 100[/tex]

[tex]Perimeter = 4 * 10 = 40[/tex]

For (e):

[tex]Length = 125[/tex]

[tex]Area = 125 * 125 =15625[/tex]

[tex]Perimeter = 4 * 125 = 500[/tex]

From (a) to (e), only side length 2 has a higher perimeter.

Hence, it disproves the statement

Answer:

The price of the new model will be $49,407.

Step-by-step explanation:

Percentages

The current model of a sports car costs $43,000. The new model is expected to cost 14.9% more than the current model.

The increase is:

14.9% of $43,000

=14.9/100 * $43,000

=$6,407

The cost of the new model is:

$43,000 + $6,407 = $49,407

The price of the new model will be $49,407.

Répondre:

r <27

Explication étape par étape:

Compte tenu de l'inégalité 5r + 9> 10r - 126

Nous devons trouver l'ensemble de solutions

5r + 9> 10r - 126

Ajouter 126 des deux côtés

5r + 9 + 126> 10r - 126 + 126

5r + 135> 10r

5r-10r> -135

-5r> -135

Divisez les deux côtés par -5 (notez que le signe changera)

-5r / -6 <-135 / -5

r <27

Par conséquent, les ensembles de solutions sont des valeurs inférieures à 27

Answer:

m + (m + 15) + (m + 2)

Step-by-step explanation:

Even thought we don't know the value of m, we can use expressions to represent it.

Hope this helps.

The required expression is m + (m + 15) + (m + 2) which represents the total number of miles Marla, Lawrence, and Jerry drove in all.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression.

Let's represent Marla drove "m" miles.

Since Lawrence drove 15 more miles than Marla.

So, this means the expression m + 15

Then Jerry drove 2 more miles than Marla.

So, this means the expression m + 2

Now, the total number of miles = m + (m + 15) + (m + 2)

This expression represents the total number of miles Marla, Lawrence, and Jerry drove in all.

#SPJ2

Answer:

- 56

Step-by-step explanation:

First solve the parenthesis,

(6 - 8) = 2

(9 - 10) = -1

(4 + 2) = 6

(6 + 3) = 9

The equation now looks like; (2)(-1) - (6)(9).

Now solve the parenthesis again,

(2 x -1) - (6 x 9)

2 x -1 = -2

6 x 9 = 54

Now, complete the last equation,

-2 - 54 = -56

-56 is the answer!

Hope this helps!!!

 - We do this because we have to get rid of the parenthesis.

Equation at the end of Step 1:

 - We do this because we have to get rid of the parenthesis.

Equation at the end of Step 2:

 - We do this to get 1 number on each side left over, and the only way to do so is multiply the remaining numbers.

 - Also, the reason we got 2 instead of -2 is because when multiplying 2 negatives by each other the quotient then turns out to be positive.

Answer:

(5-2a+6b)/2

Step-by-step explanation:

According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2

Answer:

830 miles

Step-by-step explanation:

By car, she travels 65 mph for 2 hours. 2 multiplied by 65 equals 130. She then travels 350 mph for 2 more hours by plane. 2 multiplied by 350 equals 700. Add the two distances together and you get 130 + 700 = 830
