Find the length of a side of a square with an area of 169 in^2.

Answer:

D. 13 in

Step-by-step explanation:

A square has sides of equal length.

A = L^2 where:  A = area  and  L = side

L^2 = 169

L=√169

L=13 in^2.    

The length of a side of a square with an area of 169 in2 is calculated by taking the square root of the area, which is 13 inches. The correct answer is D. 13 in.

The student is asking to find the length of a side of a square given that the area of the square is 169 square inches. The formula to calculate the area of a square is side length squared, which can be written as:

Area = side × side

To find the side length, we need to take the square root of the area:

Side = √169

Upon calculation, the side length is:

Side = 13 {in}

Therefore, the correct answer is D. 13 in.

Leo needs 6 red roses and 9 pink daisies for 3 bouquets, calculated by dividing the number of flowers needed for 5 bouquets by 5 and then multiplying by 3.

To calculate the amount of red roses and pink daisies Leo needs for 3 bouquets, we first determine the number needed for one bouquet. Since Leo needs 10 red roses and 15 pink daisies for every 5 bouquets, we divide each amount by 5 to find the number per single bouquet:

Now, we multiply the number of flowers needed per bouquet by 3 to find the total number for 3 bouquets:

Therefore, for 3 bouquets, Leo needs 6 red roses and 9 pink daisies.

Answer: The answer is 94

Step-by-step explanation: First you should pay attention to the main numbers and since more and many are addition word than you should add 7 + 4 which equals 11 then add 83 + 11 which would equal 94. Tell me if the answer is wrong and I would find another way to answer it.  

Final answer:

Linda sent 8 text messages, Jim sent 15 messages, and Dale sent 60 messages during the weekend.

Explanation:

The question asks to solve a word problem to find out how many text messages Linda, Dale, and Jim sent over the weekend.

Let's denote the number of messages Linda sent as L, Jim as J, and Dale as D.

The problem states that Jim sent 7 more messages than Linda, so J = L + 7.

Dale sent 4 times as many messages as Jim, so D = 4J.

Together they sent 83 messages, which gives us the equation L + J + D = 83.

Substituting the expressions for J and D in terms of L into the equation, we get L + (L + 7) + 4(L + 7) = 83.

This simplifies to 6L + 35 = 83. Solving for L gives us L = 8.

This means Linda sent 8 messages, Jim sent 15 messages (8 + 7), and Dale sent 60 messages (4 times 15).

Answer:

B

Step-by-step explanation:

Using the rule of logarithms

• [tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]

Given

[tex]log_{x}[/tex] ([tex]\frac{1}{8}[/tex] ) = - [tex]\frac{3}{2}[/tex], then

[tex]\frac{1}{8}[/tex] = [tex]x^{-\frac{3}{2} }[/tex]

Square both sides

[tex]\frac{1}{64}[/tex] = [tex]x^{-3}[/tex]

[tex]4^{-3}[/tex] = [tex]x^{-3}[/tex] ⇒ x = 4 → B

Step-by-step explanation:

A perpendicular dropped from center to a chord bisects the chord.

In the given figure O is the center of the circle .OB is a perpendicular dropped from center of circle to the chord AC and hence it bisects the chord .

By addition of line segments :

Length of chord AC =  AB+BC =11+11 = 22 units.

Answer:

4

Step-by-step explanation:

Let's call the width W and the length L.

We know the width is 3 less than the length, so:

W = L - 3

And we know the area is 28, so:

28 = WL

If we solve for L in the first equation:

L = W + 3

And substitute into the second equation:

28 = W (W + 3)

28 = W² + 3W

0 = W² + 3W - 28

0 = (W + 7) (W - 4)

W = -7, 4

Since W can't be negative, W = 4 units.

The width, in units, of the rectangle, if the area of the rectangle is 28 units, is  4 units.

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given:

The width of a rectangle is 3 units less than the length. The area of the rectangle is 28 units,

Write the equation as shown below,

b = l - 3   (Here, l is the length and b is the width)

l × b = 28

Solve the above equations,

l = 7 units and b = 7 - 3 = 4 units

Therefore, the width, in units, of the rectangle, if the area of the rectangle is 28 units, is  4 units.

ANSWER: THE SOLUTION OF GIVEN INEQUALITIES IS ALL REAL NUMBER EXCEPT [1.167,3.5].

Answer:

Sample Response: When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

Answer: Third option.

Step-by-step explanation:

We know that the sine function is:

[tex]f(x)=Asin(bx)[/tex]

Where "A" is the amplitude of the function( This is half the vertical distance between minimum value and maximum value of the function) and [tex]\frac{2\pi }{b}[/tex] is the period.

Observe in the graph that the amplitude is:

[tex]A=1[/tex]

And the period is 1, then "b" is:

[tex]1=\frac{2\pi }{b}\\\\b=\frac{2\pi }{1}\\\\b=2\pi[/tex]

Then the function shown in the graph is:

[tex]f(x)=sin(2\pi x)[/tex]

By definition in the transformation of the function:

When [tex]kf(x)[/tex] and [tex]k>1[/tex] then the function is stretched vertically by a factor of "k".

In this case we know that the function shown in the graph is vertically stretched by a factor of 2 to produce a new graph. Then:

[tex]k=2[/tex]

Therefore,the function that represents the new graph is:

[tex]f(x)=2sin(2\pi x)[/tex]

Answer:

Liberty Hill

Step-by-step explanation:

It rises the most over the same horizontal distance

Answer:

Liberty Hill. For every 4 feet at a horizontal distance, it rises 3 ft at the vertical rise of the street.

Step-by-step explanation:

Looking at the data, we can trace a parallel to the Cartesian Plane. As the Horizontal Distance would be the x-axis and the Vertical Axis, y-axis. So to determine the steepest hill we need to check the slope.

Like this:

Reference point (0,0)

Dixie Hill

[tex]m=\frac{40-0}{80-0}=\frac{1}{2}[/tex]

Bell Hill

[tex]m=\frac{20-0}{80-0} =\frac{20}{80}=\frac{1}{8}[/tex]

Liberty Hill

[tex]m=\frac{60-0}{80-0} =\frac{60}{80}=\frac{3}{4}[/tex]

The base Liberty Hill makes the largest angle, therefore the steepest hill.

For every 4 feet at a horizontal distance, it rises 3 ft at the vertical rise of the street.

Answer:

61 second I would say but what is the weight of the rock?

Answer:

Option B. 7.8 seconds

Step-by-step explanation:

Shyanne drops a rock from a hill at initial height of 975 feet above the ground level.

We have to calculate the time taken by rock to hit the ground.

As we know the formula of motion under gravity is

h = ut + [tex]\frac{1}{2}gt^{2}[/tex]

Here h = initial height = 975 feet

u = initial velocity = 0

t = time taken by the rock to hit the ground

g = 32.174 [tex]\frac{\text{Feet}}{\text{Second}^{2}}[/tex]

Now we plug in these values in the formula

975 = 0 + [tex]\frac{1}{2}(32.174)(t)^{2}[/tex]

975 = 16.087t²

t² = [tex]\frac{975}{16.087}[/tex]

t = [tex]\sqrt{60.60}[/tex]

t = 7.78 ≈ 7.8 seconds

Option B. 7.8 seconds is the answer.
