Answer:

379.56ft²

Step-by-step explanation:

Oh lordy why, okay we got this:

So we're going to start with the area of the square, this is easy because all of the sides are 25ft, so we just have to plug into our formula for squares (base x height):

25 x 25 = 625

Now we have to do the semicircle, remember that the formula for the area of a circle is pi x radius², we're using 3.14 for pi, so we have to find the radius (half the diameter):

25 ÷ 2 = 12.5

12.5² = 156.25

3.14 x 156.25 = 490.625‬

Normally we would stop here, but because this is only a semicircle, we have to divide by two:

490.625‬ ÷ 2 = 245.3125‬

So, now that we have our two areas, we have to subtract the semicircle from the square:

625 - 245.3125‬ = 379.6875‬

Now, I realize that his answer isn't in your cute little word bank, but that because I rounded pi, so the closest is 379.56

So, the area of the figure is 379.56ft²

if this is wrong let me know so I can fix it

hope this helps:)

Answer:

Step-by-step explanation:

h = 5 ft

diameter = 2.4 ft

Radius is half of diameter

r = 2.4/2 = 1.2 ft

Now, find the volume of the tank

Volume = πr²h

             = 3.14 * 1.2 *1.2 * 5

             = 22.608 cubic ft

Time taken to fill the tank = Volume of tank ÷ volume of gas filled per minute

= 22.608 ÷ 2.3

= 9.8

= 10 minutes

Answer:

x = 10

Step-by-step explanation:

Measure of the angle with it's vertex inside a circle = ½(sum of intercepted arcs)

Thus,

m<E = ½(HL + GF)

Substitute

60 = ½(55 + 5x + 15)

Multiply both sides by 2

2(60) = 55 + 5x + 15

120 = 5x + 70

120 - 70 = 5x

50 = 5x

50/5 = x

10 = x

x = 10

Answer:

since r > 0.361

we reject H₀

Therefore, Yes, It does suggest that  there is a linear relation between student task persistence and achievement score, since r  [0.883 ] is greater than critical value for 30 [ 0.361 ]

Step-by-step explanation:

Given the data in the question;

n = 41

r = 0.883

H₀ : population correlation coefficient = 0 ( both are independent )

Hₐ : population correlation coefficient ≠ 0 ( there is a linear relation between student task persistence and achievement score )

critical value for n = 30 is 0.361

that means, for n = 41, critical value will be less than 362

now, since r > 0.361

we reject H₀

Therefore, Yes, It does suggest that  there is a linear relation between student task persistence and achievement score, since r  [0.883 ] is greater than critical value for 30 [ 0.361 ]

3. grain of sell - point

4. strand of straight hair - line

5. Tip of a crayon​ -point

Step-by-step explanation:

1. Cellphone screen - It represents a 2 D plane surface. Hence it is a representation of a plane

2. edge of a wall - It is representation of a line

3. grain of sell - It is representation of a point

4. strand of straight hair - It is representation of a line

5. Tip of a crayon​ - It is representation of a point

Answer:

t(s) is in the acceptance region. We accept H₀ we don´t have enough evidence to justify differences in the procedures

Step-by-step explanation:

Traditional procedure bring as μ  =  8,6 h

Sample Information:

Sample size   n  = 26

Sample mean  x  =  8,4

Sample standard deviation   s  = 1

With  n  = 26  unknown population standard deviation, and population with normal distribution we should use t-student test

then  n = 26      degree of freedom  df  =  n - 1    df  =  25

significance level 0,1  with that information we look in t-student table t (c) ( two tails test)

t(c) = - 1,708

Test Hypothesis

Null hypothesis                  H₀                 x =  μ

Alternative Hypothesis     Hₐ                 x ≠  μ

Alternative hypothesis indicates that the test should considered two tails

To calculate  t(s)

t(s)  =  (  x  -   μ ) / s/√n

t(s)  = ( 8,4  -  8,6 )/ 1/√26

t(s)  = - 0,2 *  5,09 / 1

t(s) =  - 1,019

Comparing |t(s)| and |t(c)|

1,019 < 1,708     |t(s)| <  |t(c)|

t(s) is in the acceptance region. We accept H₀ we don´t have enough evidence to justify differences in the procedures

Answer:

m<1 = 70

m<2 = 110

m<3 = 82

Step-by-step explanation:

<1:

x + 75 + 35 = 180

x + 110 = 180

x = 70

<2:

<1 + x = 180

70 + x = 180

x = 110

<3:

The blank angle is 70 (b/c of 180 - 110) and vertical angles with <1

x + 70 + 28 = 180

x + 98 = 180

x = 82

Answer: 50∘ and 130∘

Step-by-step explanation:

deltamath:)

The measures of M are 50.0 and 130 degrees

The given parameters are:

[tex]\mathbf{m = 5.6cm}[/tex]

[tex]\mathbf{o = 4.6cm}[/tex]

[tex]\mathbf{\angle O = 39^o}[/tex]

The measure of angle M is calculated using the following sine formula

[tex]\mathbf{\frac{o}{sin\ O} = \frac{m}{sin\ M}}[/tex]

So, we have:

[tex]\mathbf{\frac{4.6}{sin\ 39} = \frac{5.6}{sin\ M}}[/tex]

Evaluate sin 39

[tex]\mathbf{\frac{4.6}{0.6293} = \frac{5.6}{sin\ M}}[/tex]

Cross multiply

[tex]\mathbf{sin\ M \times 4.6 = 5.6 \times 0.6293}[/tex]

[tex]\mathbf{sin\ M \times 4.6 = 3.5241}[/tex]

Divide both sides by 4.6

[tex]\mathbf{sin\ M = 0.7661}[/tex]

Take arc sin of both sides

[tex]\mathbf{M = sin^{-1}(0.7661)}[/tex]

[tex]\mathbf{M = 50.0}[/tex]

The other possible value of M is:

[tex]\mathbf{M = 180 -50.0}[/tex]

[tex]\mathbf{M = 130.0}[/tex]

Hence, the measures of M are 50.0 and 130 degrees

Answer:

56.7 and 123.3

Step-by-step explanation:

delta math

The required value of  ∠J is 56.6° for the given triangle.

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry and is represented by the symbolΔ.

Here, we are given:

j = 6.3 inches (the length of side JK)

l = 6.1 inches (the length of side KL)

∠L = 54° (the measure of angle L)

We want to find the possible values of ∠J (the measure of angle J).

Using the law of sines, we can write:

j/sin ∠J = l/sin ∠L

Substituting the given values, we get:

6.3/sin ∠J = 6.1/sin 54°

Multiplying both sides by sin ∠J and dividing by 6.1, we get:

sin ∠J = (6.3/6.1) sin 54°

sin ∠J ≈ 0.8354

∠J = sin⁻¹ (0.8354)

∠J = 56.6°

Therefore, the required value of  ∠J is 56.6°.
