Answer:

19.4%

Step-by-step explanation:

Given data

Initial height=36in

Final height= 43in

% increase= Final-initial/initial*100

Substitute

% increase= 43-36/36*100

%increase= 7/36*100

%increase= 0.194*100

%increase= 19.4%

Hence the increase is 19.4%

Answer:

m=2

Step-by-step explanation:

6m - 8 = 1/2(-4m + 16)

Distribute

6m -8 = -2m +8

Add 2m to each side

6m-8+2m = -2m +8+2m

8m -8 = 8

Add 8 to each side

8m-8+8 = 8+8

8m = 16

Divide each side by 8

8m/8 = 16/8

m=2

Answer:

105$

Step-by-step explanation:

We are told that she starts with 50$

We are also that after 30 years she earns 110% on interest

Given this information we need to find the value of the bond after the 30 years

To do so we take 110% of the initial value (50$) and add that to the initial value

So the answer = 110%(50) + 50

110%*50=55

55+50=105

So in 30 years the bond will be worth 105$

Answer: B. 1/4

Step-by-step explanation: The probability of rolling an odd number is 3/6 since there are 3 odd numbers between 1 and 6 (1, 3, 5). The probability of flipping a coin and getting tails is 1/2 since you can either get heads or tails. With this knowledge, you must multiply these two probabilities to get the probability of getting an odd number AND tails; so, 3/6 x 1/2 = 3/12 = 1/4.

Options:

Who is right, and why?

a. Neither Kurt nor Maria is right, because 3,500 should be used instead of 3,600.

b. Kurt is right, because finding 1/5 of 3,600 is not a good way to approximate 21% of 3,585.

c. Maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.

d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.

Answer:

d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.

Step-by-step explanation:

Given

[tex]Goal = 3585[/tex]

[tex]Collected = 21\%[/tex]

[tex]Kurt= 10\% * 3600 * 2[/tex]

[tex]Maria = \frac{1}{5} * 3600[/tex]

Required [Missing from the question]

Who is correct and why?

First, we calculate the actual amount collected.

[tex]Actual = Collected * Goal[/tex]

[tex]Actual = 21\% * 3585[/tex]

[tex]Actual = 752.85[/tex]

[tex]Actual = 753[/tex] --- approximate

Next, determine the estimate (round 3585 to 3600 and 21% to 20%)

[tex]Estimate = 20\% * 3600[/tex]

[tex]Estimate = 720[/tex]

Next, calculate Kurt and Maria's estimates

[tex]Kurt= 10\% * 3600 * 2[/tex]

[tex]Kurt = 720[/tex]

[tex]Maria = \frac{1}{5} * 3600[/tex]

[tex]Maria = 720[/tex]

Hence, Kurt and Maria are correct because of option (d)

Answer:

1.5 pounds

Step-by-step explanation:

24-16 is 8, so divide 8 by 16 and you get 1.5

The value of 24 ounces to pounds is 1.5 pounds.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 1 oz is equal to 1/16 pound. The value of 24 ounces to 16 pounds will be calculated as,

1 oz = 1/16 pounds

24 oz = 24 / 16

24 oz = 1.5 pounds

Hence, the value of 24 oz is 1.5 pounds.

Answer:

There are 300 milk chocolates in the bag.

Step-by-step explanation:

Since there is a bag with only milk and dark chocolates, and the probability of randomly choosing a dark chocolate is 1/12, if there are 25 dark chocolates in the bag and each is equally likely to be chosen, to determine how many milk chocolates there must be the following calculation must be performed:

1 = 25

12 = X

12 x 25/1 = X

300/1 = X

300 = X

Therefore, there are 300 milk chocolates in the bag.

Answer:

Step-by-step explanation:

Set 1

first of all we have to look at the negative numbers:

-99% = -0,99

-√80 = is almost 9

so :

-9,(9) ; -√80 ; -99%

then the positive numbers:

19% = 0,19

√9 = 3

1/9 = 0,11...

so

1/9 ; 19% ; √9

final answer:

-9,(9) ; -√80 ; -99% ; 1/9 ; 19%, √9

Set 2

descending order = from greatest to least

In this case we have to look at first at positive numbers

2/3 = 0,6

√23 = 4,...

20/3 = 6,...

23% = 0,23

so

20/3 ; √23 ; 2/3 ; 23%

negative numbers

-√34 = -5,...

so :

-4,(3) ; -√34

final answer:

20/3 ; √23 ; 2/3 ; 23% ; -4,(3) ; -√34

Answer:

12.6 cm²

Step-by-step explanation:

From the above question, the magnet is circular in shape

The area of a circle is given as:

= πr²

The area of the magnet = π × r²

Diameter = 4cm

r = Diameter/2 = 4cm/2 = 2cm

= π × (2cm)²

= 12.566370614cm²

Approximately = 12.6 cm²

The area of the magnet = 12.6cm²
