Step-by-step explanation:

Answer:

11

Step-by-step explanation:

2^3-(30/5)+9

First, you divide 30/5 because it is in parentheses and we are following this rule for order of operations:

P- parentheses

E- exponents

M- multiplication

D- division

A- addition

S- subtraction

so 30/5 = 6 and plugged in is:

2^3-(6)+9

Next, we do exponents:

2^3 = 2x2x2 = 8

plugged back in:

8-(6)+9

Now, we do the math from left to right so:

8-6=2

2+9=11

11 is your answer

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is A(x) =0.75x .

So A(12) = 9, meaning 12 bagels will cost 9 dollars.

Step-by-step explanation:

Please give me THANKS and BRAINLIES

Have a good day

The relationship between the total cost and the number of bagels purchased will be;

⇒ y = $0.75x

Where, y is total cost and x is number of bagels purchased.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Kaylee is buying bagels for a family gathering.

And, Each bagel costs $0.75.

Now,

Let number of bagels purchased = x

Total cost to purchased bagels = y

So, We get;

The relationship between the total cost and the number of bagels purchased;

⇒ y = $0.75x

Thus, The relationship between the total cost and the number of bagels purchased is;

⇒ y = $0.75x

Where, y is total cost and x is number of bagels purchased.

y=4

Answer:

27

Step-by-step explanation:

Given expression :  

    1 + 24 + ( + 3) = 1

Bring the number 1 to the left side of the equal sign. The positive 1 becomes negative 1 when brought towards the left side of the equal sign.

1 + 24 + ( + 3) - 1 = 0

Now, opening the bracket, we get

1 + 24  + 3 - 1 = 0

Negative 1 and positive 1 will get cancel

24  + 3  = 0

or 27

Therefore, the value of the numerical expression  1 + 24 + ( + 3) = 1 is 27.

Answer:

0.0588235; 0.3823529; 0.5588235

Step-by-step explanation:

Given that:

Total number of cards = 52

Total number of hearts = 13

Probability = required outcome / Total possible outcomes

Two cards are drawn without replacement :

1) What’s the probability that both of the cards are hearts?

First draw :

P(hearts 1) = 13 / 52

Second draw :

P(hearts 2) = 12 / 51

P(both cards being hearts) :

(13 /52) × (12/51) = 156 / 2652 = 26/442 = 13 / 221 = 0.0588235

2) What’s the probability that exactly one of the cards are hearts?

First draw being hearts, 2nd not hearts Or First draw not hearts and 2nd being hearts

P(first draw hearts) = 13 /52

P(2nd not hearts) = 39/51

13/52 × 39/51 = 0.1911764

P(first not hearts) = 39 /52

P(2nd being hearts) = 13 / 51

39/52 × 13/51 = 0.1911764

Hence, (0.1911764 + 0.1911764) = 0.3823529

3) What’s the probability that none of the cards are hearts

P(first draw, no hearts) = 39/52

P(second draw, no hearts) = 38/ 51

39/52 × 38/51 = 1482 / 2652 = 0.5588235

Answer:

FV= $12,450

Step-by-step explanation:

Giving the following information:

David invests $10,000 in a savings account that pays 3.5% simple interest.

To calculate the future value, we need to use the following formula.

FV= PV*(1+i*n)

n= 7

i= 0.035

PV= 10,000

FV= 10,000*(1+0.035*7)

FV= $12,450

Answer: 14:78

Step-by-step explanation: The number of apple trees sold last month was 14. The number of trees sold overall was 78. So, the ratio would be 14:78

The solutions of the quadratic equation are 3  ± √ -49.

A quadratic equation is what can be written in the form of ax²+bx+c=0.

The quadratic equation is,

x² - 6x = -58

The equation can be written as,

x² - 6x +58 = 0

Now it is in the form of the standard equation.

To determine the solutions of the quadratic equations, the formula used is

x = ( -b ± √ (b² -4ac)) / 2a

The value of a = 1

The value of b = -6

The value of c = 58

Putting the values in the formula.

x = ( 6 ± √ ((-6)² -4 * 1 * (58))) / 2 * 1

x = ( 6 ± √ (36 -232) / 2

x = ( 6 ± √ (-196) / 2

x = 3  ± √ -49

This can be written as complex numbers

i = √-1

x = 3  ± 7i

Answer:

35,890

...........

Answer:

35,890

Step-by-step explanation:

The 9 is the tens digit.

Every digit to the right of 9 becomes 0.

Start with: 35,890

Now you check the first digit to the right of the tens digit. If it is from 5 to 9, the tens digit goes up 1. If it is from 0 to 4, the tens digit remains the same.

In this case, the digit to the right of the tens digit is 2. Since 2 is from 0 to 4, the 9 remains as is and does not go up by 1.

Answer: 35,890

Răspuns:

<AOB = 43 ° și <BOC = 137 °

Explicație pas cu pas:

Găsiți diagrama atașată pentru o mai bună explicație a întrebării.

Din diagramă, <COP = <DOP + <COD

Deoarece <DOP = 90 ° și <COP = 133 °, la înlocuire

133 ° = 90 ° + <COD

<COD = 133 ° -90 °

<COD = 43 °

Deoarece <COD = <AOB (unghiuri direcționate opuse), deci <AOB = 43 °

Pentru <BOC:

Suma unghiurilor pe DBO dreaptă este de 180 °.

<BOC + <COD = 180 °

Dat <COD = 43 °

<BOC + 43 = 180 °

<BOC = 180 ° -43 °

<BOC = 137 °

Prin urmare, <AOB = 43 ° și <BOC = 137 °

Answer:

Step-by-step explanation:

To find the original price given the new price and percentage discount we use the formula

[tex]original \: \: price = \frac{100}{(100 - x)} \times new \: \: price \\ [/tex]

where

x is the percentage discount

From the question

new price = $ 84

% discount = 30%

Substitute the values into the above formula and solve

That's

[tex]original \: \: price = \frac{100}{100 - 30} \times 84 \\ = \frac{100}{70} \times 84 \\ = \frac{10}{7} \times 84 \\ = 12 \times 10[/tex]

Answer:

29.5 cm^2

Step-by-step explanation:

The diameter is 10 so the radius is 10/2 = 5

The area of the square is

A = s^2 = 7^2 = 49

The area of the circle is

A = pi r^2 = 3.14 * 5^2 =78.5

Subtract the area of the square from the area of the circle

78.5-49 =29.5

Answer:29.5

Step-by-step explanation:

The diameter is 10 so the radius is 10/2 = 5

The area of the square is
