Answer:

The area of the rectangular plot is 396 square unit.

Step-by-step explanation:

let [7p +4q ]= length of the rectangular plot. And

[ 3p+8p ] = width of the rectangular plot

given that p=2 and q=1

substitute them in the expression for the length

length=7(2)+4(1)

length=14+4

length=18units

again subject the values for p and q into the expression for the width

width=3(2)+8(2)

width=6+16

width=22units

but mathematically,

Area of a rectangular plot

= Length×width

A=L×W

given L=18units and W=22units

A=18units × 22units

A=396 square unit.

The measures of the labeled angles are 58°.

Step-by-step explanation:

Since the two angles are opposite angles, they have to be equal, meaning:

[tex]2x = 87 - x[/tex]

Solve by adding x to both sides and dividing by 3.

[tex]3x = 87 \\ x = 29[/tex]

If x = 29°, then 2x= 58°.

Since opposite angels are equal, the other angle is also 58°.

This can be checked:

Answer:

x =7

Step-by-step explanation:

  f (x)   =   g (x)

3x + 4 = 5x - 10

4 + 10  = 5x - 3x

    14    = 2x

   14/2  =  x

     7 = x

The integer that makes the division sentence x / (-2) = -3 true is 6.

Here's how we can solve for x:

Multiply both sides of the equation by -2 to isolate x:

x = -3 * (-2)

Simplify the right side:

x = 6

Therefore, dividing any number by -2 and then multiplying by -2 again should result in the original number. In this case, dividing 6 by -2 and then multiplying by -2 again gives us 6:

(6 / -2) * -2 = -3 * -2 = 6

Remember, when dividing by negative numbers, the result is flipped compared to dividing by positive numbers. This is why we need to multiply by -2 again to get back to the original number.

The integer that satisfies the division sentence x ÷ (−2) = −3 is 6, following the rule that multiplying two negative numbers yields a positive result.

To find the integer that makes the division sentence true, we look at the equation given: x ÷ (−2) = −3. To solve for x, we multiply both sides by −2, because division by a number is the inverse operation of multiplying by that number. So, we have x = −3 * (−2).

According to the rules of multiplication, when two negative numbers are multiplied together, the answer has a positive sign. Therefore, we get x = 6 as our solution. Since we know that dividing a positive number by a negative number yields a negative result, our calculated integer 6 is a valid answer because 6 ÷ (−2) indeed equals −3.

Following the rules of operations with negatives, such as in the examples 5 − (+3) that becomes 5 − 3 = 2, and 2 − (−6) that turns into 2 + 6 = 8, we can consistently apply the rule for division which mirrors the multiplication rules for signs to solve for our missing integer.

Answer:

From the table shown the years in which there was a budget deficit are

2002,2003,2005,2006,2008,2010

Step-by-step explanation:

Budget deficit is said to be when expenditure exceed or is greater than the budgeted revenue.

For 2002:

Revenue = $5 trillion and expenditure = $7 trillion

To check for budget deficit = Revenue - expenditure ( $5 trillion - $7 trillion)

=  -$2 trillion ( there was a budget deficit of $2 trillion)

For 2003:

Revenue = $8 trillion and expenditure = $10 trillion

to check for budget deficit = Revenue - expenditure ($8 trillion - $10 trillion)

= -$2 trillion (there was a budget deficit of $2 trillion)

For 2005:

Revenue = $15 trillion and expenditure = $18 trillion

to check for budget deficit = Revenue - expenditure ($15 trillion - $18 trillion)

= -$3 trillion (there was a budget deficit of $2 trillion)

For 2006:

Revenue = $8 trillion and expenditure = $10 trillion

to check for budget deficit = Revenue - expenditure ( $8 trillion - $10 trillion)

= -$2 trillion (there was a budget deficit of $2 trillion)

For 2008:

Revenue = $2 trillion and expenditure = $4 trillion

to check for budget deficit = Revenue - expenditure ( $2 trillion - $4 trillion)

= - $2 trillion ( there was a budget deficit of $2 trillion)

For 2010:

Revenue = $5 trillion and expenditure = $9 trillion

to check for budget deficit = Revenue - expenditure ( $5 trillion - $9 trillion)

= -$4 trillion (there was a budget deficit of $4 trillion)

From the table shown the years in which there was a budget deficit are

2002,2003,2005,2006,2008,2010

Budget deficit is said to be when expenditure exceed or is greater than the budgeted revenue.

For 2002:

Revenue = $5 trillion and expenditure = $7 trillion

To check for budget deficit = Revenue - expenditure ( $5 trillion - $7 trillion)

=  -$2 trillion ( there was a budget deficit of $2 trillion)

For 2003:

Revenue = $8 trillion and expenditure = $10 trillion

to check for budget deficit = Revenue - expenditure ($8 trillion - $10 trillion)

= -$2 trillion (there was a budget deficit of $2 trillion)

For 2005:

Revenue = $15 trillion and expenditure = $18 trillion

to check for budget deficit = Revenue - expenditure ($15 trillion - $18 trillion)

= -$3 trillion (there was a budget deficit of $2 trillion)

For 2006:

Revenue = $8 trillion and expenditure = $10 trillion

to check for budget deficit = Revenue - expenditure ( $8 trillion - $10 trillion)

= -$2 trillion (there was a budget deficit of $2 trillion)

For 2008:

Revenue = $2 trillion and expenditure = $4 trillion

to check for budget deficit = Revenue - expenditure ( $2 trillion - $4 trillion)

= - $2 trillion ( there was a budget deficit of $2 trillion)

Final answer:

In this problem, we are given the percentage (25%) and the amount (40), and we need to find the base. To find the base, we can set up an equation and solve for x. The base in this problem is 160.

Explanation:

In this problem, we are given the percentage (25%) and the amount (40), and we need to find the base. The base represents the whole quantity or number that the percentage is taken from.

Let x be the base. We can set up the equation: 25% of x is equal to 40, or 0.25x = 40.

To find the base, we divide both sides of the equation by 0.25: x = 40 / 0.25.

Simplifying, we get x = 160. Therefore, the base is 160.

To summarize, the percent is 25%, the amount is 40, and the base is 160.

Marcy is correct if Marcy has a 70% average in her class going into the final exam. She says "I need to get a 100% on this final so I can raise my score to 85%.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

Marcy has a 70% average in her class going into the final exam. She says "I need to get a 100% on this final so I can raise my score to 85%.

As we know,

The ratio of two integers is stated as a fraction of a hundred parts. It is a metric for comparing two sets of data

= (70% + 100%)/2

= 170%/2

= 85%

Final answer:

To raise her score to 85%, Marcy needs to get an average of 1.83 on the final exam. Since it is not possible to score more than 100%, her claim of needing a 100% is not correct.

Explanation:

To determine whether Marcy can raise her score to 85% by getting a 100% on the final exam, we need to calculate the average needed on the final exam.

To find the average Marcy needs, we can use the formula: Final Average = (Current Average * Weight) + (Final Exam Score * (1 - Weight)), where the weight represents the percentage of the final exam in the overall grade.

Let's assume the weight of the final exam is 30%. Plugging in the values, we get:

85% = (70% * 0.7) + (Final Exam Score * 0.3)

Solving for the Final Exam Score:

85% - (70% * 0.7) = Final Exam Score * 0.3

0.55 = Final Exam Score * 0.3

Final Exam Score = 0.55 / 0.3

Final Exam Score = 1.83

Since it is not possible to score more than 100% on the final exam, Marcy's claim of needing to get a 100% on the final to raise her score to 85% is not correct.

Answer:

PS = 37

Step-by-step explanation:

The opposite sides of a rectangle are congruent, thus

perimeter = 2(3x + 1) + 2(4x - 3) = 136 ← distribute and simplify left side

6x + 2 + 8x - 6 = 136

14x - 4 = 136 ( add 4 to both sides )

14x = 140 ( divide both sides by 14 )

x = 10

Hence

PS = 4x - 3 = (4 × 10) - 3 = 40 - 3 = 37
