Answers

Answer: 171 attendees

Step-by-step explanation:

I answered another similar question by you earlier, so I really hope you read through this explanation, as I will go far in depth. It's important you learn to do this so as not to simply skate through homework, then struggle with assessment.

For this problem, you have to find something called a unit price.

A unit price is the price in dollars per thing.

In this case, the price in dollars for the whole group is $132 for many things, 66 attendees.

Because 66 attendees costs $132, to find out how much money a single attendee costs, simply divide $132 by 66 to get 2$ for 1 attendee.

With this information, it is very straightforward to determine the number of attendees for $342. Simply divide $342 by $2 to get 171 attendees.

I really hope it helps :) and please, let me know if you want me to explain in more depth, the unit you are currently in is a fundamental part of early math, and it is important you understand it.

Answers

Answer:

Step-by-step explanation:

just used a calculator

23

Let’s start by making the mixed number an improper fraction. To do this you multiply the whole number by the denominator and add the numerator.

4 x 5 + 3 = 23

No we have 23/5 divided by 1/5

We have common denominators but you don’t need them for multiplying and dividing fractions. To discuss fractions you just go across, but there’s a thing. You have to flip the second fraction then you can multiply instead of divide.

So

23/5 x 5/1

23 x 5 = 115

5 x 1 = 5

115/5

This can be simplified to 23 because 5 divided by 115 is 23.

Rhombus PQRS with vertices P(-1,-3), Q(3,-4), R(4,-8) and S(0,-7)

A)Translation along the vector (4,10)
B) 90 (degrees) counterclockwise rotation about the origin.

Answers

A) Translation will slide all the points using the vector - add the vector to each point...
P’(3, 7), Q’(7, 6), R’(8, 2), S’(4, 3)

B) Rotation is tricky. 90 degrees will swap x with y and counterclockwise will reverse the sign of the new x
P’(-7, 3), Q’(-6, 7), R’(-2, 8), S’(-3, 4)

A clockwise rotation would swap the values and reverse the sign of the new y values
Half turn rotation would just reverse the values of all the coordinates

6+6=12

12= 3/4th of the entire box

4=1/4th of the entire box

12+4=16

There was 16 chocolates originally.

Calculate the work done to stretch an elastic string by 40cm if a force of 10N produces an extension of 4cm in it?

Answers

The work done to stretch an elastic string by 40cm is 20 Joules

Hooke law states that the force (F) applied to a spring is directly proportional to the extension (e).

F ∝ e

F = ke

k is the constant

Given that a force of 10N produces an extension of 4cm, hence:

F = ke

10 = k(4)

k = 2.5 N/cm

For an extension of 40cm, the work done is:

Work done = (1/2)ke²

Work done = (1/2)(2.5 N/cm)(40 cm)² = 2000Ncm = 20 Nm

Work done = 20 Joules

The work done to stretch an elastic string by 40cm is 20 Joules

Answers

Answer:

[tex]x=\frac{n}{p}m[/tex]

Step-by-step explanation:

Since we have two variables on the left side (x and p), and they are being divided, we need to do the opposite in order to get it to the other side. Therefore, we multiply both sides of the equation by m.

Doing that, we get

[tex]\frac{x}{m} m=\frac{n}{p}m\\\\\\So,x= \frac{n}{p}m\\[/tex]
