Explanation:

I'd estimate about 29 or 30 miles per hour.

The exact answer is 29.0675 miles per hour

5 2/7 x 5 1/2 = 29.0675.

The fish can swim approximately 29 miles per hour, with the exact speed being 29 1/14 miles per hour. This is determined by converting the mixed numbers to improper fractions, multiplying them together, then converting the product back to a mixed number.

The subject of this question is mathematics, specifically a real-world application of multiplication of fractions. If a person can swim at a rate of 5 2/7 miles per hour, and the fish swims 5 1/2 times faster, we have to multiply the person's speed by the speed multiplier which is the speed of the fish relative to the person.

Step-by-step explanation:

So the fish can swim approximately 29 miles per hour and the exact speed is 29 1/14 miles per hour.

Step-by-step explanation:

2/x is a fraction, but it also means divided by. More than means flip the addition to the end of the equation.

Answer:

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:

[tex]87 - 29 = 58[/tex]

The value 503.782 to the nearest tenth is 503.8

Rounding up to the nearest tenth means we want only a digit to be placed after the decimal point.

Given the value 503.782, this value to the nearest tenth will be 503.8.

Note that 1 was added to the value "7" after the decimal point. This was because the adjacent value "8" is more than 4.

Hence the value 503.782 to the nearest tenth is 503.8

Final answer:

To round 503.782 to the nearest tenth, the digit in the hundredths place is 8, which is greater than or equal to 5. Therefore, the rounded number is 503.8.

Explanation:

To adjust 503.782 to the closest 10th, we really want to take a gander at the digit in the hundredths place, which is the second digit after the decimal point. It is 7 in this instance.

Since 7 is more prominent than or equivalent to 5, we gather together the digit in the tenths place, which is the primary digit after the decimal point. For this situation, it is 8.

Therefore, 503.8 is obtained by rounding 503.782 to the nearest tenth.

To round 503.782 to the nearest tenth, we look at the digit in the hundredths place, which is 8. Since 8 is greater than or equal to 5, we round up. Therefore, the rounded number is 503.8.

Answer:

The electrician charges $46 per hour

Step-by-step explanation:

we know that

An electrician charges $322 for 7 hours of work

so

using proportion

Find out how much does the electrician charge per hour

Let

x ----> the charge per hour

[tex]\frac{322}{7}\frac{\$}{h}=\frac{x}{1}\frac{\$}{h}\\\\x=322/7\\\\x=\$46[/tex]

therefore

The electrician charges $46 per hour

The electrician charges $46 per hour.

The total charge is $322, and the total number of hours worked is 7.

To find the charge per hour, use the formula:

Charge per hour = Total charge / Number of hours

Substitute the given values into the formula:

Charge per hour = 322 / 7

Perform the division:

322 divided by 7 equals 46. Therefore, the electrician charges $46 per hour.

So, the calculation is:

Charge per hour = 46

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%.

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:

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.

Answer:

Step-by-step explanation:

[tex]x = x^{2} - 20[/tex]

[tex]x^{2} - x - 20 = 0[/tex]

[tex](x - 5)(x + 4) = 0[/tex]

[tex]x = -4, 5[/tex]

The two numbers are 5 and -4.

To find a number that is 20 less than its square, we can set up an equation where the number is represented by x. The equation then becomes x = x^2 - 20.

By re-arranging the equation, we get x^2 - x - 20 = 0. This is a quadratic equation which can be solved by factoring or using the quadratic formula.

The factored form of the equation is (x - 5)(x + 4) = 0. Therefore, the solutions for x are 5 and -4, meaning 5 and -4 are the numbers that are 20 less than their squares.

Step-by-step explanation:

it’s a rational function then it’s continue at all real numbers except when x=3

[tex]\frac{1}{x-3}[/tex] ; x≠3.

:)

Answer:

The function representing the graph is described by two equations, depending on the "x" value

f(x) = (1/3)x + 3 , if x is greater than -3.

f(x) = -x - 5 , if x is less than -3.

Step-by-step explanation:

First, you have to realize that the graph is described by two functions depending on the "x" value and that it is not defined in x= -3.

Then, for "x" values greater than -3, we look at the right line and we took 2 couple of points (-3,2) and (0,3). Using the formula for the slope and the interception with y axis.....

Slope = y2- y1 / x2- x1 = 3 - 2/ 0 - (-3) ⇒ slope = 1/3.

Interception with "y" axis y= 3

⇒ f(x) = (1/3) x + 3.

For "x" values minor than -3, we have to look the left line. Here we used the slope formula and points (-3, -2) and (-5, 0)

Slope = 0 - (-2)/ -5 - (-3) =-1. So, f(x) = -x + b.

Finally we use one of the points to replace in the formula of f(x) to find "b".

-2 = - (-3) + b ⇒ b = -5. ⇒ f(x) = - x -5

Summarizing, f(x) = (1/3)x + 3 , if x is greater than -3.

                      f(x) = -x - 5 , if x is less than -3.
