4+−2v+−18=26

(−2v)+(4+−18)=26(Combine Like Terms)

−2v+−14=26

−2v−14=26

Step 2: Add 14 to both sides.

−2v−14+14=26+14

−2v=40

Step 3: Divide both sides by -2.

Paulo's family has 1 hour 45 minutes before the trip to Scenic Lake Park.

To find out how long Paulo's family has before the trip to Scenic Lake Park, we will determine the amount of time between their arrival and the start of the trip.

Paulo's family arrived at the reunion at 8:30 A.M. The trip to Scenic Lake Park starts at 10:15 A.M.

Here's how to calculate the difference between these two times manually:

1. Convert both times to a 24-hour format (if needed):
  - Paulo's family arrival time: 8:30 A.M. is already in the morning, so it stays the same.
  - Trip start time: 10:15 A.M. is also in the morning, so it stays the same.

2. Calculate the hours remaining:
  - From 8 A.M. to 9 A.M. is 1 hour.
  - From 9 A.M. to 10 A.M. is another hour.
  - From 8:30 A.M. to 10 A.M., they have a total of 1 hour and 30 minutes.

3. Calculate the additional minutes remaining:
  - From 10:00 A.M. to 10:15 A.M. is an additional 15 minutes.

4. Add the additional minutes to the total time calculated:
  - They already have 1 hour and 30 minutes, and we add another 15 minutes to this.
  - So, the total time they have before the trip is 1 hour and 45 minutes.

Therefore, Paulo's family has 1 hour and 45 minutes of free time before the trip to Scenic Lake Park starts.

[tex]a_{87} = -1020[/tex]

Step-by-step explanation:

Given:

The given AP is.

12,0,-12,......

[tex]n=87[/tex]

The first term of an AP [tex]a=12[/tex]

Common difference [tex]d=0-12=-12[/tex]

We use the the formula for nth term of an AP.

[tex]a_{n} = a+(n-1)d[/tex]

for 87th term

[tex]a_{87} = 12+(87-1)(-12)[/tex]

[tex]a_{87} = 12+(86)(-12)[/tex]

[tex]a_{87} = 12+(-1032)[/tex]

[tex]a_{87} = 12-1032[/tex]

[tex]a_{87} = -1020[/tex]

Therefore, The 87th term of given series is -1020.

In the multiplication operation of numbers 435 and 173, the regrouped or carried over amounts are 10 (in units place calculation) and 30 (in tens place calculation). Therefore, the answer corresponds to option B: 20 and 3.

In multiplicaton problems, we often need to 'regroup' or carry values. In the multiplication of 435 and 173, regrouping is necessary. Here's how it's done:

We start by multiplying 5 from 435 with 3 from 173, to get 15. We write down 5 and carry over the 1 (or 10 from 15).

Next, we multiply the 5 in 435 with 7 (the tens-place in 173), which equals 35. We add the carry-over 1 to get 36. We write down the 6 and carry over the 3 (or 30).

Finally, we multiply the 5 in 435 with 1 (the hundreds-place in 173). Then add the carried over 3, resulting in 8.

The process is repeated with the remaining numbers in 435.

So for the multiplication above, the regrouped amounts are 10 and 30, corresponding to option B: 20 and 3.

Meaning the most she can work is 20 hours a week

Answer:

4.8 Liters.

Step-by-step explanation:

When pressure is kept constant the volume of a certain quantity of gas is proportional to the absolute temperature of the gas.

So, [tex]\frac{V_{f} }{T_{f}} = \frac{V_{i} }{T_{i}}[/tex] .......... (1)

Where, f denotes the final and i denotes the initial values.

Now, [tex]V_{i} = 3[/tex] Liters,

[tex]T_{i} = 25 + 273 = 298 K[/tex] and  

[tex]T_{f} = 200 + 273 = 473 K[/tex]

Lydia invested $ 3100 in investment lost 2 % and invested $ 4400 in investment that earned 5 %

Solution:

Given that on two investment totaling $ 7500

Lydia lost 2% on one and earned 5% on the other

Her net annual receipts were $158

To find: amount invested in both investments

Let Lydia invest $ x in first investment where she lost 2 %

Let Lydia invest $ y in second investment where she earned 5 %

Total investment given = 7500

x + y = 7500 ---- eqn 1

Net annual receipt = 158

5 % y- 2 % x = 158

[tex]\frac{5}{100}y - \frac{2}{100}x = 158[/tex]

0.05y - 0.02x = 158 ------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 7500 - y

Substitute x = 7500 - y in eqn 2

0.05y - 0.02(7500-y) = 158

0.05y -150 + 0.02y = 158

0.07y = 158 + 150

0.07y = 308

y = 4400

Thus,

x = 7500 - y

x = 7500 - 4400

x = 3100

Thus she invested $ 3100 in investment lost 2 % and invested $ 4400 in investment that earned 5 %

Final answer:

Lydia invested $3,100 at a 2% loss and $4,400 at a 5% gain. A system of equations is set up and solved using substitution to determine the amount invested in each scenario.

Explanation:

To solve Lydia's investment problem, we need to set up a system of equations based on the given information

Total investment is $7,500.

She lost 2% on one investment and earned 5% on the other.

Her net annual receipts were $158.

Let's define:
x = the amount of money invested at a 2% loss
y = the amount of money invested at a 5% gain

The system of equations can be written as:

x + y = 7500 (the total amount invested)

-0.02x + 0.05y = 158 (the net receipts from the investments)

Multiplying the second equation by 100 to simplify the decimals:

-2x + 5y = 15800

Now we can use the method of substitution or elimination to solve for x and y. For this example, we'll use the substitution method:

Solve for y in the first equation: y = 7500 - x

Substitute y into the second equation: -2x + 5(7500 - x) = 15800

Now solve for x: -2x + 37500 - 5x = 15800

Combine like terms: -7x = 15800 - 37500

-7x = -21700

Divide by -7: x = 3100

Substitute x into y = 7500 - x: y = 7500 - 3100 = 4400

So Lydia invested $3,100 at a 2% loss and $4,400 at a 5% gain.

The average precipitation per month is :

65,52 inches ÷ 12 = 5,46 inches per months

HOPE THIS HELPED ;3

The predicted amount of precipitation received between the end of March and the end of June is 0 inches.

To predict the amount of precipitation received between the end of March and the end of June, we need to find the difference in total precipitation between those two months. According to the given information, the total precipitation in inches for each month is as follows:

March: 4 inches

April: 2 inches

May: 0 inches

June: 4 inches

To find the amount of precipitation received between the end of March and the end of June, we can subtract the total precipitation at the end of March from the total precipitation at the end of June:

Total precipitation at the end of June - Total precipitation at the end of March = 4 inches - 4 inches = 0 inches

Therefore, the predicted amount of precipitation received between the end of March and the end of June is 0 inches.

Answer:

The Area of the base is 16 cm² .

Step-by-step explanation:

Given as :

The surface area of the cuboid = x = 95 cm²

The lateral surface area of the cuboid = y = 63 cm²

Let The Area of the base = z cm²

Now, Let The length of cuboid = l cm

The breadth of cuboid = b cm

The height of cuboid = h cm

According to question

∵ The surface area of the cuboid = 2 ×(length × breadth + breadth × height + height × length)

Or, x = 2 ×(l × b + b × h + h × l)

Or, 95 =  2 ×(l × b + b × h + h × l)

Or,  (l × b + b × h + h × l) = [tex]\dfrac{95}{2}[/tex]          ....1

Similarly

∵lateral surface area of the cuboid = 2 ×(breadth × height + length × height)

Or, y = 2 ×(b × h + l × h)

Or, 2 ×(b × h + l × h) = 63

Or, (b × h + l × h) = [tex]\dfrac{63}{2}[/tex]              ......2

Putting value of eq 2 into eq 1

so,  (l × b +  [tex]\dfrac{63}{2}[/tex] ) = [tex]\dfrac{95}{2}[/tex]    

Or, l × b = [tex]\dfrac{95}{2}[/tex] - [tex]\dfrac{63}{2}[/tex]    

Or,  l × b = [tex]\dfrac{95 - 63}{2}[/tex]

i.e l × b = [tex]\dfrac{32}{2}[/tex]

so, l × b = 16

Now, Again

∵The Area of the base = ( length × breadth ) cm²

So, z =  l × b

i.e z = 16 cm²

So, The Area of the base = z = 16 cm²

Hence,The Area of the base is 16 cm² . Answer

The product of two positive numbers is always positive.

So product of All positive numbers will be always positive.

For Example

( + ) × ( + ) = ( + )

The product of two negative number is always positive.

So product of even negative numbers will be always positive

For example

( - ) × ( - ) = ( + )

Also product of negative and positive is also given as a negative

( - ) × ( + ) = ( - )

and

( + ) × ( - ) = ( - )

Let the Six Positive numbers be

a, b ,c , d, e, f

So the Product of Six Positive numbers will be

[tex](+a)\times (+b)\times (+c)\times (+d)\times (+e)\times (+f)=\textrm{Positive Number}[/tex]

Let the Six Negative numbers be

-a, -b ,-c , -d, -e, -f

So the Product of Six Negative numbers will be

[tex](-a)\times (-b)\times (-c)\times (-d)\times (-e)\times (-f)=\textrm{Positive Number}[/tex]

Therefore the Product's Sign will be

a) Positive ; Positive

Answer:

c) Positive; Positive

Step-by-step explanation:

As we know it is a basic rule in mathematics, that if positive is multiplied by positive it gives a positive result always. So hence, from this rule it is proved that if we multiply 6 positive numbers, we will be getting the product which will be having positive sign. And in the second part of the questions, answer  is that if we multiply 6 negative numbers then the sign remains positive as we know it is also a basic rule in mathematics that when 2 negative numbers are multiplied by each and other then it will give a positive product. So the answer will remain 'c) Positive; Positive''

Answer:

1. First option.

2. First option.

3. First option.

Step-by-step explanation:

1. You need to remember that the Associative Property of Addition states the following:

[tex](a+b)+c=a+(b+c)[/tex]

Notice that you can group the numbers "a", "b" and "c" in any combination.

In this case, given the statement provided in the exercise:

[tex](2 + 3.4) + 6 = 2 + (3.4 + 6)[/tex]

You can identify that it ilustrates the Associative Property of Addition.

2. Remember that:

- Natural numbers are known as "Counting numbers".

- Whole numbers include positive numbers and zero.

 - Integers include the Whole numbers and the negative numbers.

- Rational numbers are those numbers that can be wriitten as a fraction:

[tex]\frac{a}{b}[/tex]

Where "a" is the numerator and "b" is the denominator.

 - Integers are a subset of Rational Numbers.

- Irrational numbers cannot be written as a fraction.

Based on this, you can conclude that [tex]\frac{1}{3}[/tex] is a Rational number.

3. The product is the result of a multiplication.

In this case the word "more than" indicates Addition.

Then, the product of 2 more than "y" and 7 can be expressed as:

[tex]7(y+2)[/tex]

Final answer:

The diameter of the pizza is 14 inches, its circumference is approximately 43.98 inches, and its area is about 153.94 square inches, calculated using fundamental geometry formulas for circles.

Explanation:

A pizza with a radius of 7 inches is given, and we are tasked with determining its diameter, circumference, and area. These are fundamental geometry calculations related to circles.

The diameter of a circle is twice its radius. So, the diameter of the pizza is 2 × 7 inches = 14 inches.

The circumference of a circle is calculated as π (Pi) times its diameter.

Therefore, the circumference of the pizza is π × 14 inches ≈ 43.98 inches (using π = 3.1416).

The area of a circle is given by π times the square of its radius (πr²).

Hence, the area of the pizza is π × 7² inches² ≈ 153.94 square inches.

These calculations provide a complete geometric understanding of the pizza's properties in terms of diameter, circumference, and area.

Step-by-step explanation:

Given coordinates are (-4,4).

Also, we need to dilate by a scale factor of 5.

The term dilation refers to changing the value of coordinate by a scale factor.

If the coordinate is said [tex](x,y)[/tex] and it is going to be dilated by a scale factor [tex]'k'[/tex].

Then the new coordinate will be (kx, ky).

So,

[tex](-4,4)\\\\k=5\\\\(-4\times5,4\times5)=(-20,20)[/tex]

The coordinate [tex](-4,4)[/tex] after dilated by a scale factor [tex]5[/tex] will be [tex](-20,20)[/tex]

[tex]6.7\sqrt{2}\ in[/tex]

Step-by-step explanation:

Let x inches be the length of the side of the square. The area of the square is

[tex]x\cdot x=x^2\ in^2[/tex]

Then

[tex]x^2=44.89\\ \\x=6.7\ in[/tex]

By the Pythagorean theorem,

[tex]d^2=6.7^2+6.7^2\\ \\d^2=44.89+44.89\\ \\d^2=89.78\\ \\d=\sqrt{89.78}=6.7\sqrt{2}\ in[/tex]

Find the length of a side by taking the square root of the area:

Side = sqrt44.89 = 6.7 inches.

Now to find the length of the diagonal multiply the side length by the sqrt of2:

Diagonal = 6.7Sqrt(2) ( exact length)
