Answer:

1 mile/hr

Step-by-step explanation:

Let the Speed of the boat still in water = a

Speed of the current = b

We know from this formula that speed = distance/time

Hence,

A canoe traveled Downstream with the current and went a distance of 15 miles in three hours.

Downstream = a + b = 15/3

a + b = 5 .........Equation 1

On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip.

Upstream = a - b = 15/5

a - b = 3 ..............Equation 2

Combining both Equation together

a + b = 5 .........Equation 1

a - b = 3 ..............Equation 2

Subtracting Equation 2 from Equation 1

2b = 2

b = 2/2

b = 1miles/hr

Since b = speed of the current which can also be called rate of the current, the rate of the current = 1 miles/hr

Answer:

Sam is correct since he followed the rule of powers.

Reina is incorrect.

Step-by-step explanation:

Rule of a power raised to a power.

[tex] (a^m)^n = a^{mn} [/tex]

To raise a power to a power, multiply the powers.

Sam is correct since he multiplied the exponents correctly.

Answer:

The w in w² + 5·w → Variable

The 2 in w² + 5·w → Exponent

The 5 in w² + 5·w → Coefficient

Step-by-step explanation:

1) The variable in an equation are the unknown values of the equation, and the values of the variables that meet the requirements of the equality are known as the solutions of the equations;

2) The exponent is the power to which a number or a variable is raised. It shows the number of times the variable or number multiples itself

3) The coefficient is the factor multiplying the variable in an equation or expression.

Answer:

w2 + 5w  →→→ Expression

The w in w² + 5·w  →→→ Variable

The 2 in w² + 5·w  →→→ Exponent

The 5 in w² + 5·w  →→→ Coefficient

the w? or the 5w in w2 + 5w →→→ Term

Q 7. First=33 Second=35 Third=37

Q 8. First=46 Second=48 Third=50

Step-by-step explanation:

Question 7. Find three consecutive odd integers whose sum if 105.

Let x=the first number (the smallest number）

Then, x+2=the second number, x+4=the third number

x+(x+2)+(x+4)=105

x+x+2+x+4=105

3x+6=105

3x=99

x=33

First=33 Second=35 Third=37

---------------------------------------------------------------------------

Question 8. The sum of three consecutive even integers is 144. Find the numbers (I think so since you didn't took the whole picture)

Let x=the first number (the smallest number)

Then, x+2=the second number, x+4=the third number

x+(x+2)+(x+4)=144

x+x+2+x+4=144

3x+6=144

3x=138

x=46

First=46 Second=48 Third=50

Answer:

18.18% error

Step-by-step explanation:

Use the percent error formula,

% error = | (measured - accepted) / accepted | x 100

Plug in the values we know:

% error = | (180 - 220) / 220 | x 100

% error = | - 0.18 | x 100

% error = 18.18% error

Answer:

The Sandbox must be 19x19 for the area to be 361.

Step-by-step explanation:

(19x19=361)

The length of the sandbox will be 19 feet.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square.

Given that Mr. Drew wants to build a square sandbox with an area of 361 square feet.

The length will be calculated by using the area formula for square;

Area of square = Length x width

Then the area of the square can be written as;

Area of square = ( Length )²

361=  ( Length )²

( Length ) = √361

( Length ) = 19feet

Therefore, the length of the sandbox will be 19feet.

To know more about an area of the square follow;

Answer:

The range of the data is 19.

Step-by-step explanation:

To solve this problem, we must remember that to calculate the range, we subtract the smallest data point in the set from the largest data point.  In this case, the largest number is 25 and the smallest number is 6.

Therefore the range is:

25 - 6

= 19

Hope this helps!

Answer:

The range is 19

Step-by-step explanation:

6, 8, 16, 22, 8, 20, 7, 25 is

List the numbers from smallest to largest

6,  7,8,   8 ,16,20, 22,25

The range is the largest number minus the smallest number

25 - 6

19

The range is 19

Answer:

[tex]Noon\ Temperature = 7F[/tex]

Step-by-step explanation:

Given

Initial Temperature = -5F

Change (by noon) = 12 degrees

Required

Determine the temperature at noon

The temperature by noon is calculated as thus;

[tex]Noon\ Temperature = Initial\ Temperature + Change[/tex]

Substitute values for Initial temperature and change

[tex]Noon\ Temperature = -5F + 12[/tex]

[tex]Noon\ Temperature = 7F[/tex]

Hence, the temperature at noon is 7F

let the number be x

so by the question , 2x+5=13

solving this we get ,

2x=13-5

2x=8

so x=4

Answer:

the number is 4

Step-by-step explanation:

let the number be ''x''

than twice the number will be 2x

now,

2x + 5 = 13

2x = 13 - 5  

2x = 8

x = 8/2    

x= 4

Answer:

Sides of the triangular birdcage are 37 cm, 38 cm, 39 cm.

Step-by-step explanation:

In the given triangular birdcage, sides of the triangle are consecutive integers.

Let sides of the triangle are x, (x + 1), (x + 2) cm.

Perimeter of a triangle = Sum of all sides of the given triangle

114 = x + (x + 1) + (x + 2)

114 = 3x + 3

3x = 111

x = [tex]\frac{111}{3}[/tex]

x = 37

Therefore, sides of the triangular birdcage are 37 cm, 38 cm, 39 cm.

Answer:

There would be 12 g of salt (12.3 g actually but rounded) and 88g of water (88.7 g actually but rounded)

Step-by-step explanation:

From the question, a 14% salt solution means 14g of salt in 100g of water.

What this means is that, the fraction of salt to water in the solution would be 14/100 which is same as 7/50

Now, we want to know the amount of salt and the amount of water in a 100g of 14% salt solution.

Looking at the ratio salt to water, we have 7 to 50

For every 50 parts of water, there are 7 parts of salt.

So the ratio of both is 7:50

For salt, the amount in grammes present will be ;

7/(50 + 7) * 100g = 7/57 * 100 = 12.3 g or 12g to the nearest whole number

The amount in grammes of water present will be ;

50/(50 + 7) * 100g = 50/57 * 100 = 87.7g or 88g to the nearest whole number

Answer:

The population was 3 times greater in 2010 than in 1970.

Step-by-step explanation:

To find how many times greater the population was, you divide the population from 2010 by the population in 1970.

[tex]\frac{2*10^{7} }{6.7*10^{6} } = 2.985[/tex] ≈ 3
