4 divided by one half

Answers

Answer:

The Answer is 2

Step-by-step explanation:

The reason why it is 2 is because just say that If a pie is cut into 4 pieces, then two pieces represent the same amount of pie that 1/2 did. We say that 1/2 is equivalent to 2/4. Fractions are determined to be equivalent by multiplying the numerator and denominator of one fraction by the same number.

The value of expression 4 divided by one half would be; 8

Known that 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Since Fractions are determined to be equivalent by multiplying the numerator and denominator of one fraction by the same number.

We need to find the expression of 4 divided by one half.

A negative divided by a negative is positive;

Anna needs 6 pints of milk to make yogurt. How many cups of milk does Anna need?

Answers

Answer:

Anna needs 12 cups.

Anna needs twice as many cups of milk as pints, so for 6 pints she needs 12 cups of milk.

The student is asking how many cups of milk are needed if Anna needs 6 pints to make yogurt. To answer this, we need to use the conversion that 1 pint is equal to 2 cups. Therefore, if Anna needs 6 pints of milk, we calculate the number of cups needed by multiplying 6 by 2.

Step-by-step conversion

Understand the conversion ratio: 1 pint = 2 cups.

Multiply the number of pints Anna needs by the conversion ratio: 6 pints × 2 cups/pint.

Calculate the total number of cups: 12 cups of milk.

So, Anna will need 12 cups of milk to make her yogurt.

ANSWER

$1,413.81

EXPLANATION

The compound interest formula is given by:

[tex]A=P(1+r\%)^t[/tex]

Where P=900 is the balance in the account, t=10 is the number of years and r=0.0462 is the rate.

We substitute the values in to the formula to get:

[tex]A=900(1+4.62\%)^{10} [/tex]

[tex]A=900(1.0462)^{10} [/tex]

This simplifies to:

[tex]A=1413.81[/tex]

Therefore $1413.81 will be in the account after 10 years.

Answer:

Correct choice is $1413.81.

Step-by-step explanation:

Initial amount P = $900

Rate of interest = r = 4.62% = 0.0462

Number of compounding periods per year n = 1 {Compounded annually}

Time = 10 years

Then balance that is future value after 10 years in the account is given by formula :

[tex]A=P\left(1+\frac{r}{n}\right)^{\left(n\right)\left(t\right)}[/tex]

[tex]A=900\left(1+\frac{0.0462}{1}\right)^{\left(1\right)\left(10\right)}[/tex]

[tex]A=900\left(1+0.0462\right)^{\left(10\right)}[/tex]

[tex]A=900\left(1.0462\right)^{\left(10\right)}[/tex]

[tex]A=900\left(1.57089499829\right)[/tex]

[tex]A=1413.80549846[/tex]

Hence correct choice is $1413.81.

A line has a slope of -4 and passes through the point (0,5). Write the equation of this line in standard form. Be sure to express the equation without fractions or decimals. (2 points, 1 for work, 1 for equation)

Answers

Answer:

Final answer in standard form of the line is [tex]4x+y=5[/tex].

Step-by-step explanation:

Given that slope of the lime m = -4

Now we need to find the equation of a line that has a slope of -4 and passes through the point (0,5). Write the equation of this line in standard form.

So plug the given slope m=-4 and the point (0,5) into point slope formula:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-5=-4\left(x-0\right)[/tex]

[tex]y-5=-4\left(x\right)[/tex]

[tex]y-5=-4x[/tex]

[tex]y=-4x+5[/tex]

[tex]4x+y=5[/tex]

Hence final answer in standard form of the line is [tex]4x+y=5[/tex].

Answer:

The equation of this line in standard form is

[tex]4x + y = 5[/tex]

Step-by-step explanation:

To find the equation of a line we need to know two points by which the line passes. You can also find the equation if you know a point through which the line passes and its slope.

For the equation of the line:

[tex]y = mx + b[/tex]

m is the slope and b is the section.

Sane that

[tex]m = -4[/tex]

To find b we substitute the point (0,5) in the equation and solve for b[tex](5) = -4 (0) + b[/tex]

[tex]b = 5[/tex]

The equation is

[tex]y = -4x +5.[/tex]

We rewrite the equation as:

4x + y = 5

Step-by-step explanation:

The given functions are;

[tex]f(x)=x^2[/tex]

The function g(x) is a vertical stretch of f(x) by a factor of 'a' units, therefore we can write g(x) in terms of f(x).

Answers

(15 games) is the minimum number of games the team must have played

Answer:

5

Step-by-step explanation:

We are given that a soccer team has played  = 25 games

The team won the games =60% of games that has played

We have to find the minimum number of additional games the team must win in order to finish the season winning 80% of the games it has played.

60% of the games=[tex]\frac{60}{100}\times 25=15[/tex]

A soccer team won games that has played =15

if the team won 80% of the games

Then,80% of 25= [tex] \frac{80}{100}\times 25=20[/tex] games

Number of games added to win 80% of the games =20-15=5

Hence, the minimum number of additional games that the team must win 80 % of the games it has played=5

if the ratio of radius of two spheres is 4:7, the ratio of their volume is?​

Answers

Answer:

64 : 343

Step-by-step explanation:

First use the radii to find the volume

1) Radius of first sphere is 4 (taken from 4:7 ratio)

   Insert it into the equation for volume of a sphere: V=4 /3πr^3

   V = (4/3)(π)(4^3)

   V = (4/3)(π)(64)

   V = 256/3 π

   Volume of the first sphere = 256/3 π

2) Radius of the second sphere is 7 (also taken from 4:7 ratio)

   Insert it into the equation for volume of a sphere: V=4 /3πr^3

   V = (4/3)(π)(7^3)

   V = (4/3)(π)(343)

   V = 1372/3 π

   Volume of the second sphere = 1372/3 π

Next, calculate the ratio by dividing the two numbers

256/3 π ÷ 1372/3 π

Answer should be 64 : 343

The simple way to do this problem is to just cube the numbers:  

4:7 becomes 4^3 : 7^3 = 64 : 343

Either way works.

If the movie starts at 6:05 and ends at 9:17 how long is it

Answers

Answer:

3h and 12min = 3.2h

Step-by-step explanation:

From 6:05 to 7:00 there are 55 minutes.

From 7:00 to 9:00 there are two hours.

From 9:00 to 9:17 there are 17 minutes.

Therefore we have

2h + 55min + 17min = 2h + 72min = 2h + 60min + 12min = 2h + 1h + 12min

= 3h + 12min = 3h + 12/60h = 3h + 1/5h = 3h + 0.2h = 3.2h

1h = 60min → 1min = 1/60h

A 7
3 8
5 9
7 B
C 11

Answers

Answer:

A = 11, B = 25/3, C = -1

Step-by-step explanation:

A linear function has the form:

f(x) = ax + b

(1)

f(3) = 8a + b = 8

f(5) = 5a + b = 9

Using the last 2 equations we can solve for 'a' and 'b'.

8a + b = 8 | 5a + b = 9

We multiply the second one by -1:

8a + b = 8 | -5a -b = -9

And then we add them together:

3a = -1

a = [tex]\frac{-1}{3}[/tex]

We then solve for 'b':

5a + b = 9

5(-1/3) + b = 9

b = 9 + 5/3

b = 32/3 = [tex]11\frac{1}{3}[/tex].

We then use this to find A, B, C.

f(x) = (-1/3)x + 32/3

(2)

f(A) = -A/3 + 32/3 = 7

[tex]\frac{-A}{3} + \frac{32}{3} = 7\\A - 32 = -21\\A = 11[/tex]

(3)

f(7) = -7/3 + 32/3 = B

25/3 = B

(4)

f(C) = -C/3 + 32/3 = 11

[tex]\frac{-C}{3} + \frac{32}{3} = 11\\C - 32 = -33\\C = -1[/tex]

What is the perimeter of the trapezoid 30 POINTS

Answers

The top is 1 unit.

The bottom is 9 units.

Use the distance formula to find the length of the side.

Give the end points coordinates

(2,2) and (6,5)

Length = √((6-2)^2 +(5-2)^2) = 5 units.

The total perimeter is the top + the bottom + 2 sides.

Perimeter = 1 + 9 + 5 + 5 = 20 units.

The perimeter of a figure is the distance around the figure.

To find the perimeter of the trapezoid shown, we can simply add all the sides. Since there are no numbers we can count each block as 1 unit.

Let's identify our values:

Top of trapezoid = 1 unit

Bottom of trapezoid = 9 units

Left and right side of trapezoid = 10 units "added together"

Now, we can add these numbers up and we will get the perimeter of the figure.

1 + 9 + 10 = 20

Therefore, the perimeter of the trapezoid is 20 units.

The table represents the function f(x). If g(x) = -(x + 1)^2 - 10, which statement is true?

Answers

Answer:

Answer C is correct.

Step-by-step explanation:

f(x) clearly has a maximum:  y = +10 at x = 0.

Analyzing g(x) = -(x + 1)^2 - 10, we see that the vertex is at (-1, -10), and that the graph opens down.  Thus, -10 is the maximum value; it occurs at x = -1.

Answer A is false.  Both functions have max values.

Answer B is false.  One max is y = 10 and the other is y = -10.

Answer C is correct.  The max value of f(x), which is 10, is greater than the max value of g(x), which is -10.

Answer D is false.  See Answer B, above.

Answers

Answer:

She omitted the y- intercept

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept)

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, - 7.5) and (x₂, y₂ ) = (2, - 5)

m = [tex]\frac{-5+7.5}{2+3}[/tex] = [tex]\frac{2.5}{5}[/tex] = 0.5, thus

y = 0.5x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, - 5), then

- 5 = 1 + c ⇒ c = - 5- 1 = - 6

y = 0.5x - 6 ← equation if line

the answer increased by 32. it is not the right option

C) [tex]y=4x+2[/tex]

if x = a

[tex]y=4a+2[/tex]

and now with x = a + 2

[tex]y(a+2)=4(a+2)+2=4a+8+2=4a+10[/tex]
