Answer:

14 miles

Step-by-step explanation:

He can row 3.5 miles in .25 hours.

If there are 60 mins in an hour. Take the .25 hour and times by 4 to get a whole hour.

Since 3.5 miles is for .25 hr, take the 3.5 times by 4 to get what he rows in a whole hour.

3.5*4= 14 miles.

The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

let the weight of basic kit be x and weight of designer kit be y.

The weight of 2 basic kites and 2 designer kites are 400g.

and, the weight of 4 basic kites and 1 designer kites are 440g.

So, the system of equation is

2x + 2y = 400.............(1)

4x + y = 440

y = 440 - 4x.............(2)

Solving equation (1) and (2), we get

2x + 2(440 - 4x) = 400

2x + 880 - 8x = 400

-6x = -440

x = 73.33

and, y= 440 - 4(73.33)

y = 146.68

Answer:

H = 3

Step-by-step explanation:

Answer:

The expressions are:

2. [tex]60h+20\ minutes[/tex]

3. [tex]2+\frac{x}{60}\ hours[/tex]

4. [tex]y+0.75\ hours[/tex]

Step-by-step explanation:

The given expressions have to be converted into algebraic expressions.

So,

2. Write an algebraic expression for the total number of minutes in h hours and 20 minutes.

Here,

h is a variable that can have any value but the 20 minutes will remain same with any number of hours.

If h is for hour, the number of minutes in h hours will be: [tex]60*h = 60h[/tex]

And there are also 20 minutes so the algebraic expression is:

[tex]60h+20\ minutes[/tex]

3. Write an algebraic expression for the total number of hours in 2 hours and x minutes.

In order to convert minutes into hour, the minutes are divided by 60

So converting x minutes into hour means

[tex]x\ minutes = \frac{x}{60}\ hours[/tex]

There are 2 hours already so the expression will be:

[tex]2+\frac{x}{60}\ hours[/tex]

4. Write an algebraic expression for the total number of hours in y hours and 45 minutes.

Converting 45 minutes to hours by dividing by 60

[tex]45\ minutes = \frac{45}{60}\ hours = 0.75\ hours[/tex]

The expression is:

[tex]y+0.75\ hours[/tex]

Hence,

The expressions are:

2. [tex]60h+20\ minutes[/tex]

3. [tex]2+\frac{x}{60}\ hours[/tex]

4. [tex]y+0.75\ hours[/tex]

Answer:

4/5 = 28/35 and 5/7 = 25/35

Explanation:

Multiply 5 times 7 to get 35, then multiply 4 times 7 for the numerator of the first fraction and 5 times 5 for the numerator of the second equation.

Answer:

The absolute value of -5 is 5. Absolute values are always the opposite of the negative number.

Step-by-step explanation:

We find the unit rate for each taco

$1.32/3 for Pacos tacos

$4.20/5 for Taco Bell

We will then get

$0.44 per taco for Pacos tacos

$0.84 per taco for Taco Bell

$0.44 < $0.84

Pacos tacos is the better deal

Answer:

x= 67 degrees and z= 54 degrees

Step-by-step explanation:

Using alternative interior angle, you can see that x is equal to 67 degrees

-In a triangle, there is 180 degrees. Since there are 59 degrees and 67 degrees in the triangle, you will just need to solve for z.

-In order to solve for z, you subtract 180-59-67= 54

Answer:

42 cups of flour

Step-by-step explanation:

12 is 4 times more than 3 (3 × 4 = 12), so we know that we need 4 times 10 1/2 (equal to 10.5) cups of flour.

All we need to do for this is do 10.5 × 4 = x and solve for x.

10.5 × 4 = 42 cups of flour

Answer:

It’s depends on the sign.

Step-by-step explanation:

For example if your question is 3x+16y-8-7x+8y then the answer would be -4x+24y-8 if they have the same variable look at them as a separate equation.

Answer:

"Like Terms" means that you can add or subtract two terms. For instance, you know that you can add and get 5. You were able to add these two 'terms' ( the '2' and the '3') because they are both numbers! However, you might also know that you cannot 'combine' 2 and x. Since 2 is a number and 'x' is not, they are not like terms.

Basically if its two numbers that are the same, For example (-2x and -4x) and have with the same variables you would add them. If they are like this (5x and -2x) you would subtract them because its a negative and positive number and get ( 3x).

Step-by-step explanation:

Answer: The speed of the current is 2 miles per hour.

Step-by-step explanation:

We know that the speed of the boat is:

S = 10 mph.

When the boat travels with the current, the speed will be:

S = 10mph + x

where x = speed of the current.

When the boat travels against the current, the speed will be:

S = 10mph - x

Now, for a given amount of time T, when the boat travels with the current, it moves a distance of 6 miles.

Then we have the equation:

(10mph + x)*T = 6mi

And against the current, in the same time the boat moves 4 mi, then:

(10 mph - x)*T = 4mi

Then we have the system of equations:

(10mph + x)*T = 6mi

(10 mph - x)*T = 4mi

Now, we can take the quotient of these two equations and get:

((10mph + x)*T)/((10 mph - x)*T) = (6mi/4mi)

(10mph + x)/(10 mph - x) = 3/2

Now we can solve this for x.

(10mph + x) = (3/2)*(10 mph - x)

10mph + x = (3/2)*10mph - (3/2)*x

x + (3/2)*x = (3/2)*10mph - 10mph

(5/2)*x = (1/2)*10mph = 5mph

x = (2/5)*5mph = 2mph.

The speed of the current is 2 miles per hour.

Given:

Height of access ramp = 6 foot

Ramp ends at a point 40 feet away along the ground.

To find:

The angle of depression in nearest tenth of a degree.

Solution:

Using the given information, draw a figure as shown below.

In a right angle triangle,

[tex]\tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}[/tex]

In triangle ABC,

[tex]\tan \theta=\dfrac{AB}{BC}[/tex]

[tex]\tan \theta=\dfrac{6}{40}[/tex]

[tex]\tan \theta=0.15[/tex]

Taking tan inverse on both sides.

[tex]\theta=\tan^{-1}(0.15)[/tex]

[tex]\theta=8.5307656[/tex]

[tex]\theta \approx 8.5[/tex]

Therefore, the angle of depression is 8.5 degrees.
