Final answer:

To find the number that 24.94 represents 29% of, you set up the equation 24.94 = 0.29 × x and solve for x, yielding x = 86.

Explanation:

To find the number that 24.94 is 29% of, we can set up an equation. If 24.94 is 29%, then we are looking for the whole (100%). We represent the whole number with a variable, let's call it x. The equation is as follows:

24.94 = 0.29 × x

To solve for x, we'll divide both sides of the equation by 0.29,

x = 24.94 ÷ 0.29

Now, let's do the math:

x = 86

Therefore, 24.94 is 29% of 86.

The football thrown by Steve has a speed of 20 meters per second, as it covers a distance of 60 meters in 3 seconds.

To calculate the speed of the football that Steve throws, we can use the basic physics concept of speed which is the distance traveled divided by the time taken. Since Steve throws the football a distance of 60 meters in 3 seconds, the calculation for the speed v is:

v = distance / time = 60 meters / 3 seconds = 20 meters per second.

Therefore, the football is traveling at a speed of 20 meters per second.

Final answer:

The speed of the football thrown by Steve is 20 meters per second, calculated by dividing the distance thrown, 60 meters, by the time taken, 3 seconds.

Explanation:

If Steve throws a football 60 meters in 3 seconds, we can calculate the speed of the football by using the formula for speed: speed = distance/time. To find the speed of the football, we simply divide the distance Steve's throw covered by the time it took for the football to cover that distance.

The calculation is as follows:

Speed = Distance / Time
Speed = 60 meters / 3 seconds
Speed = 20 meters/second

Therefore, the speed of the football is 20 meters/second

Step-by-step explanation:

From the graph given,

In order to find the equation, we need to consider the points where the curve cuts x- axis

From the graph, we have

[tex]x=-4, x= -3 \, and \, x= -1[/tex]

In factor form

[tex]x+4=0, \, x+3=0, \, and \, x+1=0[/tex]

Now, combine the factors above by multiplying together to form the equation, we have

[tex]f(x)=(x+1)(x+3)(x+4)[/tex]

Therefore, the equation of the graph in factored form is [tex]f(x)=(x+1)(x+3)(x+4)[/tex]

The question requires the equation of a graph in factored form, with the graph cutting the x-axis at -4, -3 and -1. These roots correspond to the factored form of the equation as f(x) = (x + 4)(x + 3)(x + 1). However, this equation is not listed among the choices provided. The correct option is C.

The question is asking for the equation of a graph in factored form. The graph cuts the x-axis at -4, -3, and -1.

This implies these are the roots of the equation. When a graph crosses the x-axis at a particular point, it implies the x-value of that point is a root (or zero) of the polynomial.

Therefore, the roots of the function are -4, -3, and -1. We can then convert these roots into factors by changing their signs and setting them as (x - root).

Therefore, the factored form of the equation would then be: f(x) = (x + 4)(x + 3)(x + 1). However, this equation is not listed among the choices. There might be a mistake the options provided.

It's always vital to carefully check the roots and ensure they correspond to the x values where the graph intersects the x-axis.

Therefor the correct option is C.

The equation of line parallel to given line is: [tex]y = \frac{2}{3}x-\frac{5}{3}[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]y = \frac{2}{3}x+2[/tex]

As the line is in slope-intercept form, the co-efficient of x is the slope of the line

So,

[tex]m_1 =\frac{2}{3}[/tex]

Let m2 be the slope of required line

As both the lines are parallel,

[tex]m_1 = m_2[/tex]

So,

[tex]m_2 = \frac{2}{3}[/tex]

The slope intercept form of line is:

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

Putting the value of the slope

[tex]y = \frac{2}{3}x+b[/tex]

To find the value of b, putting (1,-1) in the equation

[tex]-1 = \frac{2}{3}(1) +b\\-1 = \frac{2}{3} +b\\b = -1-\frac{2}{3}\\b = \frac{-3-2}{3}\\b = \frac{-5}{3}[/tex]

Putting b=-5/3 in the equation

[tex]y = \frac{2}{3}x-\frac{5}{3}[/tex]

Hence,

The equation of line parallel to given line is: [tex]y = \frac{2}{3}x-\frac{5}{3}[/tex]

Option C. As x approaches positive infinity, f(x) approaches positive infinity, and g(x) approaches negative infinity.

Step-by-step explanation:

we know that

Observing the table

The function f(x) is a increasing function

As the value of x increases, the value of f(x) increases

so

As x approaches positive infinity, f(x) approach positive infinity

Find the slope of the linear equation g(x)

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have the points (6, -2) and (3, 7)

substitute

[tex]m=\frac{7+2}{3-6}[/tex]

[tex]m=\frac{9}{-3}=-3[/tex]

The slope of the linear equation g(x) is negative

That means ----> Is a decreasing function

As the value of x increases, the value of g(x) decreases

so

As x approaches positive infinity, g(x) approach negative infinity

therefore

As x approaches positive infinity, f(x) approaches positive infinity, and g(x) approaches negative infinity.

The weight in 1980 is [tex]\frac{4k}{5}[/tex] kilograms

Solution:

From 1980 to 1990, Lior’s weight increased by 25%

His weight is "k" kilograms in 1990

To find: weight in 1980

This is a percentage increase problem

Let "x" be the weight in kilograms in 1980

The percentage increase is given by formula:

[tex]\text{Percentage increase } = \frac{\text{Final value - initial value}}{\text{initial value}} \times 100[/tex]

Here,

Initial value in 1980 = x

Final value in 1990 = k

Percentage increase = 25 %

Substituting the values in formula,

[tex]25 = \frac{k-x}{x} \times 100\\\\25x = 100(k-x)\\\\x = 4(k-x)\\\\x = 4k - 4x\\\\5x = 4k\\\\x = \frac{4k}{5}[/tex]

Thus the weight in kilograms in 1980 is [tex]\frac{4k}{5}[/tex]

Answer:

The number if texts sent by Chau  = 32

The number of texts sent by Laura = 24

The number of texts sent by Jose  =  96

Step-by-step explanation:

The total number of sent texts =  152

Let us assume the number of texts sent by Chau = k

So, the number of texts sent by Laura  = 8 fewer than Chau  = k - 8

Also, the number of texts sent by Jose = 4 times as many messages as Laura

=  4 x (k-8)

So, now the total number of texts = texts sent by ( Chau  + Jose + Laura)

or, 152  = k +  (k-8) + 4(k-8)

⇒ k + 5(k-8) = 152

or, k + 5 k - 40 = 152

or, 6 k  = 192

or, k = 32

So, the number if texts sent by Chau = k = 32

The number of texts sent by Laura = k - 8 = 24

The number of texts sent by Jose = 4 (24)  =  96

Answer:

x = 4

Step-by-step explanation:

2(3x+8) = 40   (By PEDMAS, distribute parentheses first)

3x (2) + 8(2) = 40    (next do multiply)

6x + 16 = 40   (subtract 16 from both sides)

6x = 40 - 16

6x = 24  (divide both sides by 6)

x = 24/6 = 4

Answer:

3 quarts of blue paint and 2 quarts of red paint

Step-by-step explanation:

Let

x ---> quarts of blue paint

y ---> quarts of red paint

we know that

You make 5 quarts of purple paint

so

[tex]x+y=5[/tex] ----> equation A

The ratio of of blue paint to red paint is

[tex]\frac{x}{y} =\frac{(1/2)}{(1/3)}[/tex]

[tex]\frac{x}{y}=1.5[/tex]

[tex]x=1.5y[/tex] ----> equation B

Solve the system by substitution

substitute equation B in equation A

[tex]1.5y+y=5[/tex]

solve for y

[tex]2.5y=5\\y=2[/tex]

Find the value of x

[tex]x=1.5(2)=3[/tex]

therefore

3 quarts of blue paint and 2 quarts of red paint

Answer:

-3         -3

1=1/2X

THEN U DIVIDE BOTH SIDES BY 1/2:

1=1/2X

1/1/2=X

1*2/1=X

2=X

Option B:

–1 is the value included in the solution set

Solution:

Given inequality is –3(x – 4) > 6(x – 1).

⇒ –3x + 12 > 6x – 6

Add 3x on both sides of the expression.

⇒ –3x + 12 + 3x > 6x – 6 + 3x

⇒ 12 > 9x – 6

Add 6 on both sides of the expression.

⇒ 12 + 6 > 9x – 6 + 6

⇒ 18 > 9x

Divide by 9 on both sides of the expression.

⇒ 2 > x

⇒ x < 2

Therefore the solution set is x < 2.

In the given options 3 and 7 are greater than the solution set.

x < 2, so 2 is also not in the solution set.

–1 is the only value which is in the solution set x < 2.

Hence, –1 is the value included in the solution set.
