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

Step-by-step explanation:

Given the question:

Raina has a fabric of area 7912 centimetre square find the largest square that can be cut from it how much piece will be left

Area of fabric = 7912 cm²

Largest square that can be cut from it :

Taking the square root of 7912

Sqrt(7912) = 88.94 cm

Hence, it can be deduced that the largest square tht can be cut from it will be 88cm

From area of a square = a²

Where area is the length of the side (since all sides are equal)

a² = 88² = 7744cm²

Hence, area left = (7912 - 7744) cm² = 168 cm²

Answer:

AC=48

Step-by-step explanation:

Since B marks the middle of A and C and AB is 24, you would need to multiply that length by two to find AC.

Answer:

x=4

Step-by-step explanation:

the sum of 18 and a number x

that's just 18+x

is equal to 22

that means that something=22

=22

put all together

[tex]18+x=22\\\\18-18+x=22-18\\\\x=4[/tex]

The required value of x is 4.

Assume that the number we're looking for is represented by 'x'. According to the problem,

The sum of 18 and x is equal to 22.

We can write this as an equation: 18 + x = 22.

To solve for x,

Isolate it on one side of the equation.

We can do this by subtracting 18 from both sides:

18 + x - 18 = 22 - 18.

This simplifies to,

x = 4.

Therefore, the value of x that satisfies the equation is 4.

The value of x is 1.4 when z = 4.0 and y = 5.6.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculations.

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

Given the equation as:

z = y/x

z = 4.0 and y = 5.6

To determine the value of x

⇒ z = y/x

Multiply by x on both sides

⇒ xz = y

Substitute the values z = 4.0 and y = 5.6

⇒ x(4) =(5.6)

Divide both sides by 4

⇒ x = (5.6)/(4)

⇒ x = 1.4

Hence, the value of x is 1.4 when z = 4.0 and y = 5.6.

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

Step-by-step explanation:

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.

Step-by-step explanation:

We need to add all four angles given (I'll use 0.5 instead of 1/2 to make the addition easier to type):

0.5 x + 0.5 x + x + x = 360

3 x = 360

x = 360/3 = 120

Therefore,  [tex]x=120^o[/tex]

two of them are 1/2 of x, that is: 120/2 = 60

Answer:

$114.54

Step-by-step explanation:

In order to answer this question, we are going to have to do some multiplication :)

First, we will find out how much Maria got paid on Monday. In order to find this, we must multiply 5.1 hours by $9.20, so

5.1 * 9.20 = 46.92

We will be using this number a little later. Next, we have to find out how much Maria got paid on Tuesday, so we have to multiply 7.35 hours by $9.20, so

7.35 * 9.20 = 67.62

Now, we will combine the numbers:

67.62 + 46.92 = 114.54

Therefore, Maria earned $114.54 this week

Hope this helps :)

105.34 and you would first add the hours together so 5.1 + 7.35= 11.45 then you would multiple $9.20 X 11.45= 105.34

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

Answer:

Equation is [tex]8M + 7P = 131[/tex]

[tex]M = \$12[/tex]

Step-by-step explanation:

Given

Jason: 6 Movies and 4 popcorn

Michael: 2 Movies and 3 Popcorn

1 Popcorn = $5

Total = $131

Required

- Write an equation to solve

Represent Movie with M and Popcorn with P

For Jason, we have:

6M + 4P

For Michael, we have:

2M + 3P

Add these parameters together

Jason + Michael = $131

[tex]6M + 4P + 2M + 3P = 131[/tex]

Collect Like Terms

[tex]6M + 2M+ 4P + 3P = 131[/tex]

[tex]8M + 7P = 131[/tex]

Hence the equation is [tex]8M + 7P = 131[/tex]

From the question, we have that

[tex]P = \$5[/tex]

Substitute 5 for P

[tex]8M + 7 * 5 = 131[/tex]

[tex]8M + 35 = 131[/tex]

Solve for M

[tex]8M = 131 -35[/tex]

[tex]8M = 96[/tex]

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 °
