Select all ratios equivalent to 20:5.

Answers

Answer 1

The answer is : 40:10

*multiply by 2

If helpful, brainliest please !

Answer 2

Answer:

40:10 & 8:2

Step-by-step explanation:

20 * 2 = 40

5 * 2 = 10

8 * 2.5 = 20

2 * 2.5 = 5

2:1 does not work because only 2 * 10 = 20, but 1 *10 = 10 and there is no 10. There is only 5.

What is logarithmic?

The exponent to which the base of the logarithm should be raised in order to obtain the number N is the logarithm of any number N, if interpreted as an exponential form. Numerous astronomical and scientific calculations involving large numbers can benefit from its use. As an inverse of the exponential function, logarithmic functions are closely related to exponential functions.

Given Equation

[tex]4log_\frac{1}{2} w + (2log_\frac{1}{2} u - 3log_\frac{1}{2} v)[/tex]

[tex]mlog_an = log_an^{m}[/tex]

equation is

[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} u^2 - log_\frac{1}{2} v^3)[/tex]

and [tex]log_an - log_am = log_a\frac{n}{m}[/tex]

and [tex]log_an + log_am = log_amn[/tex]

[tex]log_\frac{1}{2} w^4 + (log_\frac{1}{2} \frac{u^2}{v^3} )[/tex]

and [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex]

Hence the equation is [tex]log_\frac{1}{2} \frac{w^{4}u^{2} }{v^{3} }[/tex].

If a supermarket has an area of 0.25 m² on the plan, find its actual area in hectares. (1 hectare = 10 000 m²)​

Answers

Answer:

4 hectares

Step-by-step explanation:

The scale factor is:

k = 1/400

Applied to the area we consider k² as the area is the product of two dimensions.

Find the actual area:

0.25 m² : (1/400)² = 0.25 m² * 160000 = 40000 m² = 40000 * 1/10000 hectares = 4 hectares

Answer:

Step-by-step explanation:

You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional.  So set up two ratios that are = to each other

On the left

long side small triange / long side large triangle = base small triangle / base large triangle

On the right

hypotenuse/longest leg = hypotenuse / longest leg.

Problem A

Set up the similar Proportion

5/40 = x/20                Cross Multiply

40x = 20*5

40x = 100                   Divide by 40

x = 100/40

x = 2.5

Problem B

Again set up the similar triangle proportion

15/10 = x/2                  Multiply by 2

15*2/10 = x              

3 = x

for the first one x=2.5
for the second one x=3

Answer: 25

Step-by-step explanation:

she’s earned 175 so far she needs 230. So 230-175=55, so she needs 55 more dollars. 55÷2. 50(price of each bracelet) = 25

Answer: 25. 55 ÷2 = 25

Circle question of the rug

That you needed answer for is ;

3/4 pi^2  

Step-by-step explanation:

Proof  1/4 pi r^2

We can state the radius of small rug is 3ft

to show Area pi 3^2 = pi 9

If the large rug is 3x this size  

then  pi 9^2 = pi81

So the ratio here is 1 : 9 when 3 cm or 1 : 3 radius

Ratio is 1 : 9 when 1cm or 1 : 3 radius  

When 1 : 9 cm when 5cm or 1 : 3 radius  

So if we are considering an expression of the larger rug  

that shows 3: 1 more radius to that of the small.

1/4 pi^2 becomes 3/4 pi^2 of the smaller rug

As this is 3 x 1/4 pi^2 we show 3/4pi r^2

Jason buys a pair of pants for $28.97, a top for $12.82 and a scarf for $9.18. He has a gift card worth $75. If the sales tax on the purchase is $3.19, what is the total of his purchase?

Part B:
Will he have enough money left to buy a hat for $27.15?
Explain your answer.

Answers

Answer:

Explanation:

Part A:

Total purchase = 28.97 + 12.82 + 9.18 + 3.19 = 54.16$

Part B:

75$ - (54.16 + 27.15) = 75 - 81.31 = -6.31

Therefore, he won’t have enough money to buy the hat.
Part a: When you add them all together you will get $54.16

Part b: no he won’t.

This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.

1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)

The only number which has 9 as its final digit is 409

S = 2 π r (r + h) is equivalent to 2 π r (r + h) = S:

2 π r (r + h) = S

Divide both sides by 2 π r:

r + h = S/(2 π r)

Subtract r from both sides:
