Step-by-step explanation:

The length of each side of the square to the nearest whole number is 6 feet.

Given that, the area of a square is 32 square feet.

We need to estimate the length of each side of the square to the nearest whole number.

A square is a closed two-dimensional shape with four equal sides and four equal angles. The four sides of the square form the four angles at the vertices. The sum of the total length of the sides of a square is its perimeter, and the total space occupied by the shape is the area of the square. The formula to find the area of a square =a², where a=side of a square.

Now, a²=32 square feet

⇒a=√32

⇒a=5.65≈6

Therefore, the length of each side of the square to the nearest whole number is 6 feet.

Answer:

598.50

Step-by-step explanation:

Multiply the percent by the price then add that number to the price.

I added 38.50 in taxes to the price of the TV

The total cost of the TV will be $598.50 including the sales tax of 6.875%.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that in Minnesota, the state sales tax rate is 6.875%. The price tag on an HDTV gives the price as $560,

The total cost will be calculated as,

Cost = 560 x 1.06875

Cost = 598.5

Hence, the total cost will be $598.50.

Step-by-step explanation:

Equation of a line

A line can be represented by an equation of the form

[tex]y=mx+b[/tex]

Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.

We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.

Two lines with slopes m1 and m2 are perpendicular if:

[tex]m_1.m_2=-1[/tex]

The given line has a slope m1=5, thus the slope of our required line is:

[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{5}[/tex]

The equation of the line now can be expressed as:

[tex]\displaystyle y=-\frac{1}{5}x+b[/tex]

We need to find the value of b, which can be done by using the point (7,2):

[tex]\displaystyle 2=-\frac{1}{5}*7+b[/tex]

Operating:

[tex]\displaystyle 2=-\frac{7}{5}+b[/tex]

Multiplying by 5:

[tex]10=-7+5b[/tex]

Operating:

[tex]10+7=5b[/tex]

Solving for b:

[tex]\displaystyle b=\frac{17}{5}[/tex]

The equation of the line is:

[tex]\boxed{\displaystyle y=-\frac{1}{5}x+\frac{17}{5}}[/tex]

Its an obtuse triangle because one of the angle n is 98 degrees

Answer:

Obtuse Triangle

Step-by-step explanation:

First we have to find the measure of all the angles. We know that the sum of all angles in a triangles is 180 degrees.

So we add 35 and 47 which is 82 degrees.

Then we subtract 82 from 180 which is 98 degrees. Now we know that angle N is 82 degrees.

We can go ahead eliminate answer choices acute equiangular triangle (that only applies if all angles are 60 degrees) and right triangle (must have a right angle which is 90 degrees).

That now leaves us with acute and obtuse triangle. An acute triangle has angles that are less that 90 degrees. So that only leaves us with the answer choice obtuse triangle, because it has an angle of 98 degrees which is an obtuse angle.

So your answer is Obtuse Triangle.

Answer:

50.88

Step-by-step explanation:

dried apples,raisins and peanuts. One pound of the mixture is $3.18

it contains twice as much peanuts by weight than apples.

:

One pound of dried apples cost $4.48, a pound of raisins cost $2.40 and

a pound of peanuts is $ 3.44.

:

How many ounces of each ingredient are contained in one pound of the trail mix?

:

Here it is, step-by-step

:

Let a = no. of oz of apples

Let r = no. of oz of raisins

Let p = no. of oz of peanuts

:

The equation:

4.48a + 2.40r + 3.44p = 3.18(16)

:

It says p = 2a, substitute 2a for p

4.48a + 2.40r + 3.44(2a) = 3.18(16)

:

4.48a + 2.40r + 6.88a = 50.88

:

4.48a + 6.88a + 2.40r = 50.88

:

11.36a + 2.40r = 50.88

:

At this point we can say: r = (16-3a), a represents apples & peanuts here.

Substitute (16-3a) for r, solve for a;

11.36a + 2.40(16-3a) = 50.88

:

11.36a + 38.40 - 7.2a = 50.88

:

11.36a - 7.2a = 50.88 - 38.40

:

4.16a = 12.48

a = 12.48%2F4.16

a = 3 oz dried apples

then

P = 2(3)

P = 6 oz of peanuts

:

Find r:

r = 16 - 3 - 6

r = 7 oz of raisins

;

:

Check these values for a, r, p in the cost equation

4.48(3) + 2.40(7) + 3.44(6) = 3.18(16)

13.44 + 16.8 + 20.64 = 50.88; confirms our solutions

3 ounce of dried apples, 7 ounce of raisins and 6 ounce of peanuts are contained in 1 pound of the trail mix

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.

Given:

Dried apples, raisins and peanuts.

One pound of the mixture is $3.18

it contains twice as much peanuts by weight than apples.

One pound of dried apples cost = $4.48,

raisins cost = $2.40

peanuts cost = $ 3.44.

Let x be number of oz of apples

Let y be number of oz of raisins

Let z be number of oz of peanuts

So, the equation can be written as

4.48x + 2.40y + 3.44z = 3.18(16)

As, z = 2x,

4.48x + 2.40y + 3.44(2x) = 3.18(16)

4.48x + 2.40y + 6.88x = 50.88

4.48x + 6.88x + 2.40y = 50.88

11.36x + 2.40y = 50.88

Also, y= (16-3a)

11.36x + 2.40(16-3x) = 50.88

11.36x + 38.40 - 7.2x= 50.88

11.36x - 7.2x = 50.88 - 38.40

4.16x = 12.48

x = 12.48 / 4.16

x = 3

and, z = 2(3)

z = 6

Similarly, y = 16 - 3 - 6

y = 7

Hence, 3 ounce of dried apples, 7 ounce of raisins and 6 ounce of peanuts.

https://brainly.com/question/557284

Answer:

Step-by-step explanation:

If the object travels from L to M at an average speed of 10 m/s in 6 seconds, we can get the distance LM using the formula;

Speed = Distance/Time

Distance = Speed * Time

Distance = 10 * 6

Distance = 60m

Hence LM = 60m

Since LN = LM + MN

160 = 60 + MN

MN = 160-60

MN = 100m

If the object moves from M to N at an average speed of 25 m/s througj a distance od 100m, the time taken will be expressed as;

Time = distance/speed

Time = 100/25

Time = 4secs

Total time taken to move from L to N is 6secs + 4secs = 10secs

The average speed of the object for it's entire journey from L to N will be:

Average speed = Distance LN/10

Average speed for the entire journey = 160/10 = 16m/s

Hence the average speed of the object for it's entire journey from L to N is 16m/s
