There are 750 spectators of which of 420 are women and the rear are men what percent of the spectators are women
Answers
Answer: 56%
Step-by-step explanation:
There are 750 total people in this crowd.
420 are women and their percentage of the total is needed.
You get this by dividing the number of women by the total number of spectators and then multiplying by 100%:
= Number of women/ Total people * 100%
= 420 / 750 * 100%
= 56%

Michelle has a round lamp to which she wants to add beads. The diameter is 12.2 inches. What is the circumference?
Answers
Answer: 38.34 inches
Step-by-step explanation:
The lamp is round which means that the circumference can be calculated by the formula:
= Pie * diameter
Pie = 22/7
Diameter = 12.2
Circumference = 22/7 * 12.2
= 38.34 inches

Tickets to an outdoor concert cost $15 for general admission tickets and $25 for VIP tickets. Ticket sales totaled $4500. Write an equation that models this relationship. Let x = the number of general admission tickets sold Let y = the number of VIP tickets sold
Answers
Answer: 15x + 25y = 4500
Step-by-step explanation:
The cost per general admission tickets is $15 and if x is used to represent the number of general admission tickets then 15 has to be multiplied by x and that gives the expression 15x
The same with the VIP tickets, each one cost $25 and y is used to represent the number of VIP tickets sold, so if you want to find out how much a number of VIP tickets cost then you will have to multiply 25 by y and that derives the expression 25y.
A combination of both tickets has to equal $4500 because that is amount they were both sold to get in total.
15x + 25y = 4500
Find an equation of the line perpendicular to the graph of 14x-7y=8 passing through the point at (-2,5)
Answers
Answer:
Equation of line perpendicular to given graph is:
[tex]y = -\frac{1}{2}x+4[/tex]
Step-by-step explanation:
Given equation of line is:
14x-7y=8
First of all, we have to convert the given equation into slope-intercept form to find the slope of the line
The slope-intercept form is:
[tex]y = mx+b[/tex]
Now
[tex]14x-7y=8\\14x-8 = 7y\\\frac{7y}{7} = \frac{14x-8}{7}\\y = \frac{14}{7}x - \frac{8}{7}\\y = 2x - \frac{8}{7}[/tex]
The co-efficient of x is 2 so the slope of given line is 2
Let m1 be the slope of line perpendicular to given line
The product of slopes of two perpendicular lines is -1
[tex]m.m_1 = -1\\2.m_1 = -1\\m_1 = -\frac{1}{2}[/tex]
The equation for line perpendicular line to given line will be:
[tex]y = m_1x+b\\y = -\frac{1}{2}x+b[/tex]
To find the value of b, putting (-2,5) in the equation
[tex]5 = -\frac{1}{2}(-2) + b\\5 = 1+b\\b = 5-1\\b = 4[/tex]
The final equation is:
[tex]y = -\frac{1}{2}x+4[/tex]
Hence,
Equation of line perpendicular to given graph is:
[tex]y = -\frac{1}{2}x+4[/tex]

B. -3x -24; x 8
C. -3x <-24; x>-8
D. -3x >-24; x>-8
Answers
Step-by-step explanation:
Lets convert each sentence into an algebric inequality.
Product of -3 and a number (let it be x) :-[tex] = > - 3 \times x = - 3x[/tex]
-3x is atleast -24[tex] = > - 3x \geqslant - 24[/tex]
Lets solve the inequality.
Now , divide -3 on both the sides -
[tex] = > \frac{ - 3x}{-3} \geqslant \frac{ - 24}{ - 3} [/tex]
[tex] = > x \geqslant 8[/tex]
Natasha used 75 beads to make a necklace
for her sister. Of the 75 beads, 25 were square.
The rest of the beads were round. What is the
ratio of round to square beads on the necklace?
Answers
Answer: 2:3
Step-by-step explanation:
25/75 beads are square. Thus, 1 out of every 3 beads (1/3) is square. With this information, 2/3 of the beads are round because 1 - 1/3 = 2/3.
This means that the ratio of round to square beads is 2:3.

7. The two equations have different solution steps. Do they have the same solution?
Use the distributive property to show why this answer makes sense.
Answers
Answer:
Yes, they have the same solution.
Step-by-step explanation:
Both of these equations have the same solution, just different steps.
To solve Ravi's equation, first we use the distributive property.
2(x+14) = 40
Multiply 2 by x and 14
2x + 28 = 40
Subtract 28 from both sides.
2x + 28 - 28 = 40 - 28
2x = 12
Divide by 2 on both sides.
2x/2 = x
12/2 = 6
so x = 6.
Fran's equation is the same equation as Ravi's second step.
Her equation of 2x + 28 = 40 is Ravi's after distributing 2.
Answer:
2(x+14)=40
2(x+14)=40
÷2 ÷2
x+14=20
-14 -14
x=6
2x+28=40
-28 -28
2x=12
÷2 ÷2
x=6
