It would take 6 people to build the wall 1 day
It takes 4 days to build the same wall with 6 people based on the given ratio.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
It takes 4 people 6 days to build a wall.
The number of people days taken = 4 x 6 = 24 people takes
This means if one person wants to build them it takes 24 days.
For 6 people the time taken will be 24/6 = 4 days.
Hence "It takes 4 days to build the same wall with 6 people based on the given ratio".

Eric and Erica have $5.40 between the two of them. If you double the amount of money Eric has and halve the amount Erica has, then they would have the same amount of money. How much money does Eric have?
Answer:
$1.08
Step-by-step explanation:
Use a system of equations. Let x represent eric's money and y represent erica's money.
x+y=5.40
2x=1/2y
Let's solve for y in the second equation and substitute it into the first.
Double both sides.
4x=y
Substitute
x+4x=5.40
5x=5.40
Divide by 5
x=$1.08
So eric has $1.08

Step-by-step explanation:
A bakery sold 224 chocolate cupcakes in a day, which was 56% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Hence, 440 cupcakes were sold on that day.
The bakery sold a total of 400 cupcakes that day, with 224 of them being chocolate cupcakes, representing 56 precent of the total.
Use the concept of percentage defined as:
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred.
Given that,
A bakery sold 224 chocolate cupcakes in a day.
The 224 chocolate cupcakes represent 56% of the total number of cupcakes sold that day.
To find the total number of cupcakes sold,
Use the percentage given and some simple math.
If 56% of the cupcakes sold were chocolate cupcakes and that amounts to 224 cupcakes,
Set up the following equation:
0.56 x Total number of cupcakes = 224 cupcakes
To find the total number of cupcakes,
Divide both sides of the equation by 0.56:
Total number of cupcakes = 224 cupcakes / 0.56
Calculating this,
The bakery sold a total of 400 cupcakes that day.

IMPORTANT: Jamie says that the expressions 6x-2x+4 and 4(x+1)are not equivalent because one expression has a term that is subtracted and the other does not. Do you agree? Explain.
20 pts and Brainliest!
I need an answer similar to how this answer looks:
Yes, because in the expression 2(2n-1) you will first need to multiply 2 by 2n, your result is 4n, and then you multiply 2 by 1, you get 2, so the answer will be 4n-2, as mentioned up in the problem. So yes, Chris is correct.
Answer:
The reasoning of Jamie is incorrect
Step-by-step explanation:
No, because in the expression 4(x+1) you will first need to multiply 4 by x, your result is 4x, and then you multiply 4 by 1, you get 4, so the answer will be 4x+4, as mentioned up in the problem.
Also in the expression 6x-2x+4 ,you will first need to subtract 2x from 6x, your result is 4x ,and then you add 4 , so the answer will be 4x + 4
Finally,we obtain
6x-2x+4 = 4x + 4 and 4(x+1) = 4x + 4
Conclusion:
The reasoning of Jamie is NOT correct.
Answer:
Np Jamie is wrong
Step-by-step explanation:
No, because in the phrase 4(x+1), you must first multiply 4 by x, which gives you 4x, and then multiply 4 by 1 to get 4, giving you 4x+4, also, in the phrase 6x-2x+4, you must subtract 2x from 6x to get 4x, and then add 4 to get 4x + 4x.
Our final solution is:
4(x+1) = 4x + 4 and 6x-2x+4 = 4x + 4

Z + 43 = a straight line which needs to equal 180 degrees.
Z = 180 - 43 = 137
answer: z = 137 degrees
Answer:
so we know that 43 and y are congruent so y = 43.
we also know that y + x has to equal 180
so
180 - 43 = 137
so x is 137. We also know that z and x are congruent, so therefore z is 137.

If cos Θ = -0.1, find the value of cos (Θ + 2π) + cos(Θ + 4π).
Answer:
cos(Θ + 2π) + cos(Θ + 4π) = -0.2
Step-by-step explanation:
The cosine funciton is periodic with period 2π, so we have ...
cos(Θ) = cos(Θ + 2π) = cos(Θ + 4π) = -0.1
__
The sum is ...
cos (Θ + 2π) + cos(Θ + 4π) = -0.1 +(-0.1) = -0.2

Applying the chord theorem, since chords RS and TU are equal, then the measure of arc RS is: 106°.
What is the Chord Theorem?The chord theorem states that if two chords in a circle are equal in length, then their corresponding minor arcs will also be equal in measure.
Since chords RS = TU, therefore:
m(RS) = m(TU)
Substitute
8x - 14 = 7x + 1
8x - 7x = 14 + 1
x = 15
m(RS) = 8x - 14
Plug in the value of x
m(RS) = 8(15) - 14
m(RS) = 106°

A simple random sample of 100 8th graders at a large suburban middle school indicated that 83% of them are involved with some type of after school activity. Find the 99% confidence interval that estimates the proportion of them that are involved in an after school activity. a) (0.733, 0.927) b) (0.653, 0.927) c) (0.633, 0.877) d) (0.783, 0.788) e) (0.733, 0.727) f) None of the above
Using the z-distribution, as we are working with a proportion, the 99% confidence interval is given by:
a) (0.733, 0.927).
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
The other parameters are p = 0.83, n = 100, hence the bounds of the interval are given as follows.
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.83 - 2.575\sqrt{\frac{0.83(0.17)}{100}} = 0.733[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.83 + 2.575\sqrt{\frac{0.83(0.17)}{100}} = 0.927[/tex]

find x in the right triangle
Answer:
C. √147
Step-by-step explanation:
Set the values of the triangle up in the Pythagorean Theorem.
a² + b² = c²
x² + 7² = 14²
Take 7 and 14 to the power of 2.
x² + 49 = 196
Subtract 49 from both sides.
x² = 147
Take the square root of both sides. There will only be one answer since lengths cannot be negative.
x = √147
Answer:
C
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 7² = 14²
x² + 49 = 196 ( subtract 49 from both sides )
x² = 147 ( take square root of both sides )
x = [tex]\sqrt{147}[/tex]

An electronics store reduced the price of a TV from $1100 to $946. What was the percent of decrease?
Answer:
14%
Step-by-step explanation:
946/1100 = 0.86
1 - 0.86 = 0.14 = 14%
Answer: 14%
Answer:
14% decrease
Step-by-step explanation:
Percentage Decrease = [ (Starting Value - Final Value) / |Starting Value| ] × 100
Percentage Decrease = [ (1100 - 946) / |1100| ] × 100
Percentage Decrease = [ (154) / |1100| ] × 100
Percentage Decrease = [ 0.14] × 100
Percentage Decrease = 14
