The 17 students on the math team want to raise $483.62 to buy practice books. They have already raised $218.25. If each student raises the same amount, how much more money must each student raise?

Answer:

the answer would be m=1/3 and b=-4

Step-by-step explanation:

Y=X-4

the X= 1 almost all the time in an equation unless otherwise your given an equation for "x". so x  is automatically 1/3 which would be your slope, and then then looking at the equation the end part of the equation is your starting point.so you look at the end of the equation and  the -4 is were youd start your point on the graph.

Divide 46 on both sides to get f(x)=((x+2)^3-3)/46. The domain ranges from negative infinity to infinity. The range ranges from -infinity to infinity as well because the exponent is 3, so the resulting number may be negative.

Remember, when graphing cubics, there is always two turns. The following graph is from Desmos.

let's say Artaud's age is "x", its opposite will then be -x, so

Answer:

9.2 hours for the total drive

To determine how long it took for an object to travel 230 miles at 25 miles per hour, divide the distance by the speed, which results in 9.2 hours.

This problem is a straightforward application of the formula for calculating time when distance and speed are known. The formula is Time = Distance ÷ Speed.

In this case, the distance (d) is 230 miles and the speed (v) is 25 miles per hour. Using the formula:

Therefore, it took 9.2 hours for the object to travel a distance of 230 miles at a speed of 25 miles per hour.

Answer:

[tex]1000 {e}^{.06 \times 5} = 1349.86[/tex]

The correct answer is B.

After 5 years with continuous compounding at 6%, $1,000 will grow to approximately $1,349.86.

To find the future value of an account with continuous compounding, we use the formula:

A = Pe^(rt)

where:

In your case:

P = $1,000, r = 6% (or 0.06 in decimal form), and t = 5 years.

So plug these values into the formula:

A = $1,000 * e^(0.06*5)

After you calculate this, you'll find that the value of A is approximately $1,349.86. Therefore, after 5 years, your balance would be $1,349.86 so the answer is (b).

The slope-intercept form:

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

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-1, -10) and (1, 0). Substitute:

[tex]m=\dfrac{0-(-10)}{1-(-1)}=\dfrac{10}{1+1}=\dfrac{10}{2}=5[/tex]

Put the coordinates of the point (1, 0) to the equation of line:

[tex]0=5(1)+b[/tex]

[tex]0=5+b[/tex]      subtract 5 from both sides

[tex]-5=b\to b=-5[/tex]

For the line's equation, calculate the slope from the provided points to get 5, and use one point to find the y-intercept, which is -5. The line's equation is y = 5x - 5.

To find the equation of a line in slope-intercept form, which is y = mx + b.

We need to determine the slope (m) and the y-intercept (b).

Given two points on the line, (-1, -10) and (1, 0), we can calculate the slope using the formula

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}\\ m = \frac{0-(-10)}{1-(-1)}\\ m = 5[/tex]

Next, we use one of the points to find the y-intercept, b. If we use the point (1, 0), we can substitute the slope and the coordinates into the slope-intercept equation:

0 = (5)(1) + b, which simplifies to b = -5.

Thus, the equation of the line is y = 5x - 5.

Typo free question:

so, we know both the rectangular prism and the cylinder got filled up to a certain height each, the same height say "h" cm.

we know the combined volume of both is 80 cm³, so let's get the volume of each, sum them up to get 80 then.

Final answer:

To find the height of the water in each container, we must calculate the volumes of the rectangular prism and the cylinder, set equations based on their volumes that add up to 80 cm³, and solve for the heights of the water in each container.

Explanation:

To solve this, the volume of the containers and then the height of the water in each container must be determined.

The volume of the rectangular prism can be found with the formula:
Volume = length × width × height. So, the volume = 4cm × 2cm × height of water for the rectangular prism.

The volume of the cylinder is calculated using the formula: V = πr²h, where 'r' is the radius and 'h' is the height of water for the cylinder. Given the radius is 1 cm, the formula simplifies to V = π × 1 cm × height of water.

Knowing the combined volume of the water is 80 cm³, we set up the equations considering the volume of water held by each container and solve for the heights of water in both the rectangular prism and the cylinder. The calculations will provide the individual heights of water, ensuring they add up to the total volume of 80 cm³.

Answer:

The solution set is { x | x[tex]\leq[/tex] -2 or x[tex]\geq[/tex] 1}

Step-by-step explanation:

The given inequality is

[tex]x^{2} +x-2>0[/tex]

Let us factor [tex]x^{2} +x-2[/tex]

so we have

[tex](x+2)(x-1)>0[/tex]

Let us find zeros of [tex](x+2)(x-1)[/tex]

[tex](x+2)(x-1)=0[/tex]

[tex]x+2=0[/tex]   or  [tex]x-1 =0[/tex]

[tex]x= -2[/tex] or [tex]x=1[/tex]

so we have intervals (-∞ , -2) , (-2 , 1) and (1, ∞)

we need to find in which interval is [tex]x^{2} +x-2[/tex] is greater than 0

so we will assume the value of x in each interval and will plug it in [tex]x^{2} +x-2[/tex] and will check if we get negative or positive value

Let us check the sign of [tex]x^{2} +x-2[/tex] in (-∞ , -2)

we can take x=-3 and plug it in [tex]x^{2} +x-2[/tex]

so we have

[tex](-3)^{2} +(-3)-2= 9-3-2= 4[/tex]   ( which is greater than 0)

This shows  (-∞, -2) is one of the solution set

similarly we can check the sign of [tex]x^{2} +x-2[/tex] in (-2,1)

we take x= 0 , so we have

[tex]0^{2} +0-2=-2[/tex]  ( which is less than 0)

This shows  (-2,1) is not the solution set

now we check the sign of [tex]x^{2} +x-2[/tex] in (1 ,∞)

we can assume x= 2, so we have

[tex]2^{2} +2-2 = 4[/tex]  ( which is greater than 0)

This shows  (1 ,∞) is the solution set

Hence the solution set in interval notation  (∞ ,-2)∪(1,∞)

we can write this as { x | x[tex]\leq[/tex] -2 or x[tex]\geq[/tex] 1}

Answer:

Step-by-step explanation:

Expand

4x - 28 = 0.3x + 0.6 + 2.11

Simplify 0.3x + 0.6 + 2.11 to 0.3x + 2.71

4x - 28 = 0.3x + 2.71

Add 28 to both sides

4x = 0.3x + 2.71 + 28

Simplify 0.3x + 2.71 + 28 to 0.3x + 30.71

4x = 0.3x + 30.71

Subtract 0.3x from both sides

4x - 0.3x = 30.71

Simplify 4x - 0.3x to 3.7x

3.7x = 30.71

Divide both sides by 3.7

x = 30.71/3.7

Simplify 30.71/3.7 to 8.3

x = 8.3

Step-by-step explanation:

We have that, 'The multiplication of two or more quantities may be expressed as the repeated addition of the same quantities'.

i.e. multiplication of two or more terms is equal to adding as many copies of one of them.

i.e. a × b = a + a + ... ( 'b' number of times ) = b + b + .... ( 'a' number of times )

For example,

2 × 4 = 8

2 × 4 = 2 + 2 + 2 + 2 = 8 i.e. adding 2 four times

2 × 4 =  4 + 4 = 8 i.e. adding 4 two times

or

3 × 7 = 21

3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 i.e. adding 3 seven times

3 × 7 = 7 + 7 + 7 = 21 i.e. adding 7 three times.

Hence,  'The multiplication of two or more quantities may be expressed as the repeated addition of the same quantities'.

The multiplication of two or more quantities can be expressed as the product of the same quantities in mathematics.

Multiplication is a fundamental arithmetic operation that combines two or more numbers to find their total value. It represents repeated addition and is denoted by the "×" or "*" symbol. For example, multiplying 5 by 3 results in 5 * 3 = 15, indicating that the value is added five times.

In mathematics, the multiplication of two or more quantities may be expressed as the product of the same quantities. For example, if you multiply 2 by 3, the product is 6. This concept of multiplication applies to all quantities, whether they are numbers or variables.

Answer:

x=90: y =43

Step-by-step explanation:

Given is a triangle.  In ABC, AB = AC is given.  also angle C = 47 is given.

AD is angle bisector of angle A

Since two sides are equal, ABC is isosceles.  We have angle C = angle B

Hence angle B = 47 degrees.

Angle A = 180-(B+C) = 180-94 = 86

So angle y = 1/2 (86) = 43

Consider triangle BAD.

We have got two angles as 47 and 43.

Hence third angle is 180-(47+43) = 90

So x=90, y = 43

Answer:

19 i think

Step-by-step explanation:

Answer:

The students baked at least 19 pies.

Step-by-step explanation:

We know that each of the pies were cut into 8 pieces. Since the students sold at least 224 pieces of pie, we can use these equations to figure out how many pies were sold and how many were made by the students.

Total number of pies = total number of slices sold/number of slices per pie

Total number of pies = 224/8

Total number of pies = 28

Pies made by students= total number of pies-pies made by school cafeteria

Pies made by students= 28-9

Pies made by students= 19

Answer:

option B

Given : |x + 4| < 5

A. –5 > x + 4 < 5

B. –5 < x + 4 < 5

C. x + 4 < 5 and x + 4 < –5

D. x + 4 < 5 or x + 4 < –5

In general , |x|< n where n is positive

Then we translate to -n < x < n

|x + 4| < 5

5 is positive, so we translate the given absolute inequality to

-5 < x+4 < 5

So option B is correct

Answer:

it will take 15 weeks for Nancy’s account to have TWICE as much money as Fred’s account

Step-by-step explanation:

Fred brown and his sister, Nancy, each have $15 in the bank

Initially both Fred and Nancy have $15

Every week Nancy plans to add $3 to her account

Let 'n' be the number of weeks she plans to add in her account

for 1 week, $3

For n weeks , its 3n

So amount of money in Nancy's account after 'n' weeks = 15 + 3n

Fret plans to add $1 to his account each week

for 1 week, $1

For n weeks , its 1n

So amount of money in Fred's account after 'n' weeks = 15 + 1n

Now we need to find out 'n' when

Nancy's account = 2 times of Fred's account

15 + 3n = 2(15+1n)

Distribute 2 inside the parenthesis

15 + 3n = 30 + 2n

Subtract 2n on both sides

15 + n = 30

Subtract 15 on both sides

n = 15

Hence, it will take 15 weeks for Nancy’s account to have TWICE as much money as Fred’s account

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

9 > 2

i.e. 9 is to the right of 2 on a horizontal number line

As we know that in the Cartesian plane, upper most is for y- positive coordinate, lower most is for y- negative coordinate

Similarly, right most is for x-positive coordinate and left most is for x- negative coordinate.

And we have 9>2

Both 2 and 9 are positive numbers so, both numbers must be in the right part of axis.

And 9 is always right of 2 on a horizontal number line.

Hence, Option 'C' is correct.
