NEED HELP!! Can someone help me solve this puzzle I think I have that first two right?

Step-by-step explanation:

The diagram is very helpful, so really go off of that. Coordinates are written in the form (x,y). If you look at the signs (either there's a negative sign, - , or no sign at all, meaning it's +) for each number in a coordinate pair, you can see where each coordinate should go.

If you look at the last example (3, -3), the first digit is positive + and the second digit is negative - . When you look at the diagram, coordinates in the form of (+, -) are put in quadrant 4.

Step-by-step explanation:

Sean's real average speed was less than his predicted 40 mph.

Calculating average speed involves dividing the whole distance traveled by the total time it took to cover that distance. Speed is the rate of movement of something at a specific time.

Hence, Sean's real average speed was less than his predicted 40 mph.

Answer:

∠ 1 = 25° , ∠ 2 = 155°

Step-by-step explanation:

∠ 1 and ∠ 2 are a linear pair and sum to 180° , that is

x - 6 + 5x = 180

6x - 6 = 180 ( add 6 to both sides )

6x = 186 ( divide both sides by 6 )

x = 31

Then

∠ 1 = x - 6 = 31 - 6 = 25°

∠ 2 = 5x = 5 × 31 = 155°

Answer:

The series -1+2+(-4)+8+... is an arithmetic series because it has a common difference between consecutive terms. Specifically, the common difference is -4 - 2 = -6.

To determine whether the series is convergent or divergent, we need to find its sum. The sum of an arithmetic series is given by the formula:

sum = (n/2)(a1 + an)

where n is the number of terms in the series, a1 is the first term, and an is the nth term.

Since the series is infinite, we cannot determine its sum using this formula. However, we can determine its sum by taking the limit as n approaches infinity. Using the formula above, we find that the sum is equal to:

sum = (infinity/2)(-1 + infinity)

Since the series contains an infinite number of negative terms, it is divergent.

What is Proportionalities (Ratios)?

It is possible to represent absolute connections using ratios or proportions, independent of the variables' actual raw values. For instance, if your business always produces widgets packaged in bundles of 20 widgets each, you will always have a 20 widgets to 1 bundle ratio regardless of how many bundles you produce. Accordingly, if you produce 100 bundles per day, you will have produced 2000 widgets in a single day.  The proportion of widgets to bundles is constant and does not change. As long as the other ratio factor quantity is known or can be known, the ratio or proportion can then be used as a conversion factor to calculate the number of an unknown quantity of one ratio factor.

In our problem, we know that there are 11 boys : 9 girls in the school. We also know that there are 124 more boys than girls.

If we let x equal the number of girls in the school, the number of boys will then be x+124. We know the ratio of boys to girls and produce a conversion factor to determine the number of girls present in the school:

( number of boys)[tex]$\left(\frac{\text { girls }}{\text { boys }}\right)=$[/tex] number of girls

[tex](x+124)\left(\frac{9}{11}\right)=x[/tex]

Note that since we are looking to find the number of girls, it appears in the numerator of the conversion factor and boys in the denominator. If we were looking for the number of boys, we would flip the conversion factor to have the number of boys in the numerator and girls in the denominator.

Now let's simplify the equation and solve for x :

[tex]\begin{aligned}(x+124)\left(\frac{9}{11}\right) & =x \\\frac{9 x+1116}{11} & =x \\9 x+1116 & =11 x \\1116 & =11 x-9 x \\1116 & =2 x \\\frac{1116}{2} & =x=558\end{aligned}[/tex]

If we have 558 girls, the number of boys is then:

x+124=558+124=682boys

Adding the number of boys and girls together, we will have the total number of students in the school: 558+682=1240 students

Answer: n= 1

Step-by-step explanation:

8n+7=-4n+19

First, subtract 7 from both sides

8n = 4n +12

Then add 4n from both sides

12n = 12

Then divide by 12 from both sides

n= 1

If you can please give me a Brainliest, thank you!

Answer: n = 1

Step-by-step explanation:

First, you could start off by bringing the -4n to the left side:

8n + 7 = -4n+19  →  12n + 7 = 19

Next, you take the 7 on the left side of the equals sign and subtract it from the 19:

12n + 7 = 19 → 12n = 12

Finally, you divide the 12 on the right by the 12 on the left:

12n = 12  →  n = 12/12

A number over itself will always be 1, so n = 1.

The fraction of the cake that was ron's pieces is 1/5.

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

Since Mrs Jones gave 1/5 of a cake to her neighbour, the remaining fraction will be:

Answer:

x = -4

Step-by-step explanation:

(4x-5)/(3x+5) = 3

1. Multiply both sides by 3x+5

  4x-5 = 3(3x+5)

2. Expand

   4x-5 = 9x+15

3. -4x from both sides

   -5 = 5x+15

4. -15 from both sides

  -20 = 5x

   x = -4

It is greater than 3

x = 4

We can solve the equation as

(4x-5) = (3x+5)*3

4x-5=9x+15

x = 4

a) Using a system of equations, the amount invested in the mutual fund that earned 6% was $1,600.

b) The amount invested in the mutual fund that earned 4% was $200.

A system of equations is two or more equations solved concurrently.

A system of equations is also called simultaneous equations.

Total investment = $1,800

Profit from investment A = 6%

Profit from investment B = 4%

The total investment profit = $76

Let A = Investment A and B = Investment B

A + B = 1,800

A = 1,800 - B

0.06A + 0.04B = 76

0.06(1,800 - B) + 0.04B = 76

108 - 0.06B + 0.04B = 76

108 - 0.02B = 76

-0.02B = -32

Let x be the total weight or all the weight of rocks .

3 = 49.3 % * x

3 = 49.3 * 1 / 100 * x

3 * 100 = 49.3 * x

300 = 49.3 * x

In this problem we have the case of a ball that experiments a free fall, that is, a case of an uniform accelerated motion due to gravity. The position of the ball as a function of time is represented by a quadratic equation:

y' = y + v · t + 0.5 · g · t²

Where:

And to determine the time related to the highest point, we need to rearrange the expression into its standard form:

y' - k = C · (t - h)²

Where:

First, write the quadratic equation:

y' = y + v · t + 0.5 · g · t²

y' = 10 + 16 · t - 8 · t²

Second, complete the square until the standard form is found:

y' - 10 = 16 · t - 8 · t²

y' - 10 = - 8 · (t² - 2 · t)

Step-by-step explanation:

First, you should translate everything into math. So,

"∠B is 2 more than 3 times the measure of ∠C" translates into B = 3C + 2....(1)

"...∠B and ∠C are complementary angles" translates to B + C = 90...............(2)

Now, all that's left to do is to solve for B and C. So, we'll take equation (1) and substitute it into equation (2) as follows:

(3C + 2) + C = 90

4C + 2 = 90

4C = 88

C = 22

Plugging C = 22 back into either equation (1) or (2) gives us

B = 90 - 22 = 68 (or B = 3(22) + 2 = 68)

Thus, ∠B = 68º; ∠C = 22º

The number of feet of light used by Chad is 176 feet

From the question, we have the following parameters that can be used in our computation:

Length = 55 feet

Width = 48 feet

We start by calculating the distance from the end of the width till the beginning of the length

This is represented by the following Pythagoras theorem

Distance = √(Length² + Width²)

So, we have

Distance = √(55² + 48²)

Evaluate

Distance = 73

The number of feet is then calculated as

Feet = Length + width + distance

So, we have

Feet = 55 + 48 + 73

Evaluate

Feet = 176

Hence, the total distance is 176 feet
