The sand pit for the long jump has a width of 3.65 meters and a length of 9.5 meters. The cheerleaders want to cover the pit with a sign cheering on their team. How many square meters of paper will the cheerleaders need to cover the sand pit?

Answer:

(4.9793, 6.2207)

Step-by-step explanation:

Given the data:

Sample size, n = 34

Sample mean, m = 5.6

Standard deviation, s = 2.2

Confidence interval = 90%

Using the relation :

m ± Zcritical * s/√n

Zcritical at 90% confidence interval = 1.645

Confidence interval ;

5.6 ± (1.645 * 2.2/√34)

5.6 ± 0.6206533

Lower boundary = 5.6 - 0.6206533 = 4.9793

Upper boundary = 5.6 + 0.6206533 = 6.2207

Answer:

Step-by-step explanation:

To find the answer, calculate the area of the rectangles.

Area of rectangle = Length * Width

Rectangle A                                   Rectangle B                         Rectangle C

= 6 * 3                                              = 9 * 9                                  = 5 * 4

= 18 cm²                                           = 81 cm²                              = 20cm²

Rectangle D                                  Rectangle E

= 9 * 2                                              = 7 * 2                                

= 18 cm²                                           = 14 cm²

The two rectangles are therefore A and D.

Answer:

Last option

Step-by-step explanation:

That is your best choice because that is the option that tells you the angles are congruent and not the sides. I could be wrong tho.

The hypothesis to proof that the base angles of the isosceles triangle are congruent will be AC≅AB

An isosceles triangle is a triangle that has at least 2 congruent sides. The congruent sides are the legs of the triangle while the remaining side is called the base. The angles on the base is called the base angles.

The base angles of an isosceles triangle are congruent. The base angles are

∠BCA and ∠CBA and they are congruent. The sides AC and AB are congruent. AC≅AB.

Therefore, the hypothesis to proof that the base angles of the isosceles triangle are congruent will be as follows:

Answer:

No invariant point

Step-by-step explanation:

Yo!

When we translate a form, in this case a polygon We must observe the direction of the vector. Since our vector is:

1) Let's apply  that translation to this polygon, a square. Check it below:

2) The invariant points are the points that didn't change after the transformation, simply put the points that haven't changed.

Examining the graph, we can see that no, there is not an  invariant point, after the translation. There is no common point that belongs to OABC and O'A'B'C' simultaneously. All points moved.

=11x - 2

Step-by-step explanation:

Hey there!

The answer to your question is y = -3/7x - 9/7

To answer this, we need to get y by itself on one side, so we need to solve for y:

3x - 7y = 9

-7y = 3x + 9

y = -3/7x - 9/7

Answer:

  13/2 or 6 1/2

Step-by-step explanation:

We can write the question in the form of an equation:

  13/16 = n×1/8

Multiplying by 8 gives ...

  8×13/16 = n

  13/2 = n = 6.5

The number of 1/8 in 13/16 is 6 1/2 or 13/2.

Answer:

The graph is the equation 3x + 4y = 12 is attached below.

Step-by-step explanation:

Given the equation

3x + 4y = 12

First,

We need to determine the y-intercept:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

substitute x = 0 in the equation 3x + 4y = 12

3x + 4y = 12

3(0) + 4y = 12

0 + 4y = 12

4y = 12

divide both sides by 4

4y/4 = 12/4

y = 3

Thus, the y-intercept is: (0, 3)

Now, check the attached graph below.

Determining the y-intercept of the equation from the graph

From the graph, it is clear

at x = 0, y = 3

Thus, the y-intercept is (0, 3)

Determining the x-intercept of the equation from the graph

From the graph, it is clear

at y = 0,

3x + 4(0) = 12

3x = 12

x = 4

Thus, the x-intercept is (4, 0)

The graph is the equation 3x + 4y = 12 is attached below.

Answer

1)90°. 2)51°. 3)39°.

Step-by-step explanation:

1) it is straight so it is 90°

2)51° because the kite is symmetrical so it should be the same as the other side

3)90+51=141

180-141=39° so it is 39°

Answer: y=-17/6x+7/3

Step-by-step explanation:

Answer:

1) ∠A=84°

2) ∠C=20°

Step-by-step explanation:

1)

First, find ∠C:

(I'm assuming the exterior angle of 126° makes a straight line with ∠C)

The angles on a straight line always add up to 180. Therefore:

∠C+126=180

∠C=180-126

∠C=54

Then find ∠B:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+∠B+54=180

∠A+∠B=126

(we know ∠A=2(∠B))

2(∠B)+∠B=126

3(∠B)=126

∠B=42

Now, find ∠A:

∠A=2(∠B)

∠A=2(42)

∠A=84°

2)

First, find ∠B:

(Again, I'm assuming the exterior angle of 100° makes a straight line with ∠B)

The angles on a straight line always add up to 180. Therefore:

∠B+100=180

∠B=180-100

∠B=80

Then find ∠A:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+80+∠C=180

∠A+∠C=100

(we know ∠A=4(∠C))

4(∠C)+∠C=100

5(∠C)=100

∠C=20°

Volume of a Pyramid

Given a pyramid of triangular base area Ab and height H.

The volume of the pyramid is calculated by the formula:

Answer:

The base is 5

The exponent is 4

[tex]5\cdot 5\cdot 5\cdot 5=5^4[/tex]

And the value is 625

Step-by-step explanation:

Exponentials

If a number is multiplied by itself n times like shown below:

[tex]x\cdot x\cdot x\cdot ...x[/tex]

It can be written in exponential form:

[tex]x\cdot x\cdot x\cdot ...x=x^n[/tex]

Where x is the base and n is the exponent.

In the expression:

[tex]5\cdot 5\cdot 5\cdot 5[/tex]

The base is 5

The exponent is 4

Writing the expression using an exponent:

[tex]\mathbf{5\cdot 5\cdot 5\cdot 5=5^4}[/tex]

And the value is 625

Answer:

4) b^10

5) 15x^11y^6

6) 8y^5x + 3x

Step-by-step explanation:

b^6 + b^4 = b^10 because this is multiplication. So you have to add the degrees

(3x^3y^5)(5x^8y^1) = 15x^11y^6. This is because

3 *5 = 15.

x^3 +x^8 = x^11

y^5 + y^1 = y^6.  

You have to add the degrees since this is also multiplication.

(2y^2)(4xy^3) + 3x = 24y^5x^2. This is because

2 * 4 = 8

y^2 + y^3 = y^5

x + 0 = x

Therfore, it is (8y^5x) + 3x as the final answer.

Answer:

Step-by-step explanation:

The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.

  exterior angle = 360°/72 = 5°

The interior angle is the supplement of this.

  interior angle = 180° -5° = 175°

The measure of one interior angle is 175°; one exterior angle is 5°.

Answer:

67 ≤ x ≤ 73

Step-by-step explanation:

The absolute value of a real number x is the non negative value of x. Therefore the absolute value of x (|x|) = x for x ≥ 0 and -x for x < 0.

An expression |x - a| = b signifies that x - a = b or -(x - a) = b

Given that |x − 70| ≤ 3, hence:

|x − 70| ≤ 3

x - 70 ≤ 3 or -(x - 70) ≤ 3

x ≤ 3 + 70 or x - 70 ≥ -3

x ≤ 73 or x ≥ -3 + 70

x ≤ 73 or x ≥ 67

67 ≤ x ≤ 73

Hence the solution of |x − 70| ≤ 3 is 67 ≤ x ≤ 73
