Answer:

x ≥ 25

Step-by-step explanation:

In the seventh grade, fifty students are trying for sports supplies to raise at least $2000. They already have $750.

Let us assume that each student has to raise $x more to meet the goal.

Then, a total of 50 students will raise $50x more.

Therefore, the inequality to solve for x will be  

750 + 50x ≥ 2000

⇒ 50x ≥ 1250

⇒ x ≥ 25 (Answer)

Final answer:

Each seventh grade student should raise at least $25 in order to collectively meet the goal of raising $2000 for their sports supplies after having already raised $750.

Explanation:

The goal amount for the seventh grade sports supplies fundraiser is $2000. They have already raised $750, leaving them with $1250 still needed to reach their goal. If there are 50 students working on the fundraiser, we can set up an inequality to determine how much money each student should raise minimally to meet the goal of $2000. Here's the inequality:

Let x be the amount each student needs to raise.

50x + $750 ≥ $2000

To solve for x, we subtract $750 from both sides of the inequality:

50x ≥ $2000 - $750

50x ≥ $1250

Now divide both sides by 50 to find the amount each student should raise:

x ≥ $1250 / 50

x ≥ $25

Therefore, each seventh grade student should raise at least $25 to meet the $2000 goal.

y-8=5/6(x-12)

Step-by-step explanation:

y-y1=m(x-x1)

y-8=5/6(x-12)

The required equation of the line is [tex]\rm y = \dfrac{5}{6}x-2[/tex].

Given that,

The equation of the line is,

[tex]\rm y = \dfrac{5}{6}(x-10)[/tex]

It passes through the point (12, 8).

We have to determine

The equation of the line is parallel to the given line.

According to the question,

The equation of the line is,

[tex]\rm y = \dfrac{5}{6}(x-10)[/tex]

The slope of the line [tex]\rm m_1[/tex] is 5/6.

If the two lines are parallel to each other then the slope of these lines is the same.

[tex]\rm m_1 = m_2\\\\\dfrac{5}{6} = \dfrac{5}{6}[/tex]

Therefore,

The equation of line passes through the point (12, 8) is,

[tex]\rm( y -y_1) = m (x-x_1)\\\\(y-8) = \dfrac{5}{6} (x-12)\\\\6 (y-8) = 5(x-12)\\\\6y-48=5x-60\\\\6y = 5x-60+48\\\\6y = 5x-12\\\\y = \dfrac{5}{6}x- \dfrac{12}{6}\\\\y = \dfrac{5}{6}x-2[/tex]

Hence, The required equation of the line is [tex]\rm y = \dfrac{5}{6}x-2[/tex].

Answer:

The inequality is [tex]l\times (3.25)\leq 107.25[/tex]

Step-by-step explanation:

Given: Area of volleyball net= [tex]107.25 ft^{2}[/tex]

          Width of Volleyball net= [tex]3.25 \ ft[/tex]

Considering the volleyball net is in rectangular shape and l and w is length and width respectively.

Area of rectangle= [tex]l\times w[/tex]

Now, using formula to form inequality

⇒ [tex]l\times (3.25)\leq 107.25[/tex]

Next, using the inequality to find length of Volleyball net.

∴  [tex]l\times (3.25)\leq 107.25[/tex]

Dividing both side by 3.25

⇒ [tex]l= \frac{107.25}{3.25} = 33\ ft[/tex]

∴ l= 33 ft

The possible length of Volleyball net is 33 ft.

Question 4:  [tex]\frac{1}{2x}, x\neq 0[/tex]

Step-by-step explanation:

Question 3

g(x) * h(x) means to multiply both the functions given.

Also note the distributive property:

[tex](a+b)(n+p)=an+ap+bn+bp[/tex]

Now, lets multiply:

[tex]g(x)*h(x)=(4x+1)(x^2-3)\\=(4x)(x^2)-3(4x)+1(x^2)-1(3)\\=4x^3-12x+x^2-3\\=4x^3+x^2-12x-3[/tex]

The 2nd answer choice is right

Question 4

[tex](\frac{f}{g})(x)[/tex]  means to divide both the functions and simplify, if possible. Lets do this:

[tex](\frac{f}{g})(x)=\frac{6x-3}{12x^2-6x}=\frac{3(2x-1)}{6x(2x-1)}=\frac{3}{6x}=\frac{1}{2x}[/tex]

This is the correct answer.

The restriction on the domain is any x value that we CANNOT PUT IN THE FUNCTION.

We know we cannot divide by 0, so what makes this fraction division by 0??

If we put x = 0, the function is undefined. So x CANNOT be 0.

Third answer choice is right.

Answer:

A. 10%

Step-by-step explanation:

Let events A nad B be:

A = an employee is a female

B = an employee is under the age of 30.

Use formula

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

There are 200 employees, 150 of them are female, then

[tex]P(A)=\dfrac{150}{200}=\dfrac{3}{4}=0.75[/tex]

There are 200 employees, 40 of them are under the age of 30, then

[tex]P(B)=\dfrac{40}{200}=\dfrac{1}{5}=0.2[/tex]

The probability of randomly selecting an employee who is a female or under the age of 30 is 85%, then

[tex]P(A\cup B)=0.85[/tex]

Thus,

[tex]0.85=0.75+0.2-P(A\cap B)\\ \\0.85=0.95-P(A\cap B)\\ \\P(A\cap B)=0.95-0.85=0.1[/tex]

Therefore, the probability of randomly selecting an employee who is a female and under the age of 30 is 0.1 or 10%.

Votes received by Wayne is 112

Solution:

To find: votes received by Wayne

Let the vote received by Wayne be "x"

Juan received 4 times as many votes as Wayne

Therefore,

Juan votes = 4 times as many votes as Wayne

Juan votes = 4x  ---- eqn 1

Neal received twenty less votes than Juan

Neal votes = twenty less votes than Juan

Neal votes = Juan votes - 20

Neal votes = 4x - 20 ---- eqn 2

Kerry got half as many votes as Neal

Kerry votes = half of neal votes

Kerry votes = [tex]\frac{4x - 20}{2}[/tex]  ---- eqn 3

The total votes cast in the election was 1,202

Wayne votes + Juan votes + Neal votes + Kerry votes = 1202

Plug in eqn 1 , eqn 2, eqn 3

[tex]x + 4x + 4x - 20 + \frac{(4x - 20)}{2} = 1202\\\\2x + 8x + 8x - 40 + 4x - 20 = 1202 \times 2\\\\22x - 60 = 2404\\\\22x = 2404 + 60\\\\22x = 2464\\\\x = 112[/tex]

Answer:

Area =  [tex]2w^2+12w+16[/tex]

Step-by-step explanation:

We let the width of the pool be "w"

We know the length is twice as long as width, so the length is:

2w

So,

Width = w

Length = 2w

Since a sidewalk with 2 feet width goes around the pool completely, the area enclosed by pool + sidewalk would have 2 feet around it, so its length and width would be:

Width = w + 2 + 2 = w + 4

Length = 2w + 2 + 2 = 2w + 4

The area of a rectangular region is always length * width, so the expression for area of pool and sidewalk would be:

[tex](w+4)(2w+4)\\=2w^2+4w+8w+16\\=2w^2+12w+16[/tex]

If we let the width of the swimming pool be "w", the expression for the area of pool and sidewalk is:

Area =  [tex]2w^2+12w+16[/tex]

Answer:

m∠1 = 50°

m∠2 = 88°

Step-by-step explanation:

Each triangle's angles have to add up to 180°. Use supplementary angles theorem to help solve.

Answer:

2.) m/_1 = 50

3. )m/_2=88

Step-by-step explanation:

2.) the line that the exterior angle 140 is on is a straight line. this means it is 180 degrees. 180 - 140 = 40. the box in the left corner means it is a right angle or 90 degrees. evey triangle is 180 degrees so add 40 and 90 to get 130 and then subtract 130 from 180 to get 50 which is the angle number 1.

3.)the line 120 is on is a straight line so we do 180 minus 120 to get the angle inside. it is 60. 60 +32 = 92. 180 - 92 is 88 degrees.

"all real values except x not-equals 7 and the x for which f (x) not-equals negative 3"

Step-by-step explanation:

Domain and Range of Functions

Given the function f(x), the domain of f is the set of all the values that x can take such f(x) exists. The range of f is the set of all the values that f takes.

We have a problem where we have to find the domain of a composite function. Let's recall that being f and g real functions, then

[tex]g\circ f=g(f(x))[/tex]

is the composite function of f and g.

We know the domain of f is the set of all real values except 7, and the domain of g is the set of all real values except –3.

Since f is the innermost function, the domain of the composite function is directly restricted by the domain of f. So, x cannot be 7.

Now, g takes f as its independent variable, and we know the domain of g excludes -3. It can be found that f(x) cannot be -3 because it will cause g not to exist.

Thus, the domain of [tex]g\circ f[/tex] is

All real numbers except x=7 and those where f(x)=-3

The number that is 2/3 of the way from 7 to 13 on a number line is 11. This is found by calculating 2/3 of the distance between the two numbers and adding it to the starting number.

To find the number that is 2/3 of the way from 7 to 13 on a number line, you first calculate the distance between the two numbers, which is 13 - 7 = 6. Then you take 2/3 of that distance, which is 2/3 * 6 = 4. Lastly, you add this result to the starting number, in this case, 7, giving you 7 + 4 = 11. Therefore, the number that is 2/3 of the way from 7 to 13 is 11.

The half-life h is calculated to be approximately 2.41.

To determine the half-life h from the given half-life function:

[tex]\[ Q(t) = 28550 \cdot \left( \frac{3}{4} \right)^{\frac{t}{h}} \][/tex]

we need to solve for h in the equation:

[tex]\[ \left( \frac{3}{4} \right)^h = \frac{1}{2} \][/tex]

To solve for  h , we take the natural logarithm (ln) of both sides of the equation:

[tex]\[ \ln \left( \left( \frac{3}{4} \right)^h \right) = \ln \left( \frac{1}{2} \right) \][/tex]

Using the logarithmic property [tex]\(\ln(a^b) = b \ln(a)\)[/tex], we get:

[tex]\[ h \ln \left( \frac{3}{4} \right) = \ln \left( \frac{1}{2} \right) \][/tex]

Now, solve for h :

[tex]\[ h = \frac{\ln \left( \frac{1}{2} \right)}{\ln \left( \frac{3}{4} \right)} \][/tex]

Calculate the natural logarithms:

[tex]\[ \ln \left( \frac{1}{2} \right) = \ln(0.5) \approx -0.6931 \\\[ \ln \left( \frac{3}{4} \right) = \ln(0.75) \approx -0.2877 \][/tex]

Now, divide these values to find  h :

[tex]\[ h = \frac{-0.6931}{-0.2877} \approx 2.41 \][/tex]

So, the half-life  h  is approximately:

[tex]\[ h \approx 2.41 \][/tex]

Therefore, the half-life  h  rounded to the nearest hundredth is:

h = 2.41
