Answer:

No, because the longest side is too short to be the hypotenuse of a right triangle.

Step-by-step explanation:

To see if the sides form a right triangle

6² + 8² = 9²

36 + 64 = 81

100 ≠ 81

The the 3rd side is too short

Answer:

The F-value is approximately 4.57

Step-by-step explanation:

The given parameters are;

The number of oceanfront homes in the sample, n₁ = 21 homes

The standard deviation of the selling prices, s₁ = $45,600

The number homes in the sample of homes one to three blocks from the ocean, n₂ = 18 homes

The standard deviation, s₂ = $21,330

The level of significance, α = 0.01

The F-test is given as follows;

[tex]F = \dfrac{s_1^2}{s_2^2}[/tex]

Therefore, we get;

F = 45,600²/21,330² ≈ 4.57

The F-value ≈ 4.57

The critical value from the F-table = 1.86236.

In this exercise we have to use the knowledge about force to calculate the critical force, in this way we find that:

[tex]F-value: 4.57[/tex]

We know that the information given by the text is:

The F-test is given as follows:

[tex]F=(S_1^2)/(S^2_2)[/tex]

So we have:

[tex]F=(45.600^2)/(21.330^2)=4.57\\[/tex]

Step-by-step explanation:

Answer: Total price to pay with 4 snacks = $48

Total price to pay with x snacks =36+3x

Step-by-step explanation:

Given: Jayden is going to see a movie and is taking his 3 kids.

Each ticket cost = $12

Cost of all tickets = 3 x $12

= $36

Price for each snack = $3

Price for 4 snacks = $3 x 4

= $12

Total price to pay = Cost of all tickets + price of all snacks

Total price to pay with 4 snacks = $(36+12)

= $ 48

Price for x snacks =  $3x

Total price to pay with x snacks =36+3x

Answer:

He has $1.87 change left after purchasing 7 packs of chalk.

Step-by-step explanation:

20/2.59 = 7.722 approx.

So Bruce can purchase 7 packs of chalk at $2.59 each.

Change left

= 20 -7*2.59

= $1.87

Answer:

A. 41

B. 1,590

C. .1

Step-by-step explanation:

A.

the equation is l*w=A

9.2*4.5=A

41.4=A

rounded it would be 41

B.

the equation is pi*r^2=A

3.14*22.5^2=A

3.14*506.25=A

1,589.6=A

^round this up to get 1,590

C.

what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)

.5*.2/2=A

.1/2=A

.05=A

.05+.05=0.1

Answer:

[tex]\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Part A:

The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].

What we're given:

Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]

Part B:

The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]

Part C:

The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].

What we're given:

Substituting given values, we get:

[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]

Answer:

[tex]{ \bf{2x - 5y = 5 - - - (a)}} \\ { \bf{x + y = 2 - - - (b)}} \\ (a) - 2(b) : \\ - 7y = 1 \\ y = - \frac{1}{7} \\ x - \frac{1}{7} = 2 \\ x = \frac{15}{7} [/tex]

Answer:

[tex]x = \frac{15}{7} , \ y = - \frac{1}{7}[/tex]

Step-by-step explanation:

2x - 5y = 5  ---------- ( 1 )

 x + y = 2  ------------ ( 2 )

x = 2 - y ---------( 3 )

Substitute x in ( 1 ) :

                         2( 2 - y) - 5y = 5

                             4 - 2y - 5y = 5

                                - 7y = 5 - 4

                                   -7 y = 1

                                       [tex]y =- \frac{1}{7}[/tex]

Substitute y in ( 2 ) :

                         [tex]x + y = 2\\\\x -\frac{1}{7} = 2\\\\x = 2 + \frac{1}{7}\\\\x = \frac{14 + 1}{7}\\\\x = \frac{15}{7}[/tex]

Answer:

50

Step-by-step explanation:

from the question that we have been given, we have to find out the next number after 36.

John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.

This can be seen below:

14 + 8 = 22

14 +22 =36

14 +36 =50

therefore the next sequence would be 50

200 actual miles

Step-by-step explanation:

Find the actual distance by multiplying 50 by 4, since there are 50 miles in 1 inch.

50(4)

= 200

So, there are 200 actual miles between the two cities.

I want to help you but ... What's the question?

=======================================================

Explanation:

There are A = 13 hearts and B = 4 copies of "7"

The count A+B = 13+4 = 17 may seem like it's the count of hearts or "7" cards, but we're double counting the 7 of hearts. So the true count is actually 17-1 = 16

There are 16 cards we want (either a heart or a "7") out of 52 total. Therefore, the probability is 16/52 = (4*4)/(4*13) = 4/13

Answer:

The length of QR is approximately 18.3 cm

Step-by-step explanation:

The given parameters are;

The length of the side PR = 23 cm

The length of the side PQ = 22 cm

The measure of the angle QPR = 48°

By cosine rule, we have;

[tex]\overline{QR}^2 = \overline{PR}^2 + \overline{PQ}^2 - 2 \times \overline{PR} \times \overline{PQ} \times cos(\angle QPR)[/tex]

Plugging in the values gives;

[tex]\overline{QR}^2 = 23^2 + 22^2 - 2 \times 23 \times 22\times cos(48^{\circ}) \approx 335.84[/tex]

[tex]\therefore \overline{QR} \approx \sqrt{335.84} \approx 18.3[/tex]

The length of QR ≈ 18.3 cm

Answer:

The cylindrical one

Step-by-step explanation:

We know that the container does not have anything inside it, and we only want the surface, so we will figure out the surface area. The less surface area the package has, the less plastic is used.

The surface area for a cylinder is 2πrh +2πr². Plugging 5 in for r (the radius) and 19 in for the height, we get

2π(5)(19) + 2π(5)² = 753.98

The surface area for a rectangular prism is 2(wl + hl +hw), with 10 being the width, 12 being the length, and 19 being the height in this example, resulting in

2(10*12 + 19 * 12 + 10 * 19) = 1076

The surface area for the cylinder will clearly have less surface area/plastic

Answer:

x=34

Step-by-step explanation:

The angles are corresponding angles so they are equal if m is parallel to n

x+27 = 2x -7

Subtract x from each side

x+27 -x =2x-x-7

27 = x-7

Add 7 to each side

27+7 = x-7+7

34 =x

Answer:

Mike= 240 boxes

Sarah= 120 boxes

Step-by-step explanation:

Mike and Sarah are packing boxes at a company

Mike packs 30 boxes each hour, after an 8 hour shift the number of boxes he will pack is

= 30×8

= 240

Sarah packs 15 boxes each hour, afterr an 8 hour shift the number of boxes she will pack is

= 15×8

= 120

Hence after the 8 hours shift Mike will pack 240 boxes while Sarah will pack 120 boxes

Answer:

The amplitude is 3 and the period is 10π/9.

Step-by-step explanation:

The standard cosine function is in the form:

[tex]y=a\cos(b(x-c))+d[/tex]

Where |a| is the amplitude, 2π/b is the period, c is the phase shift, and d is the vertical shift.

We have the function:

[tex]f(x)=\displaystyle 3\cos\frac{9}{5}t[/tex]

We can rewrite this as:

[tex]\displaystyle f(x)=(3)\cos\left(\frac{9}{5}\left(t-0\right)\right)-(0)[/tex]

Therefore, a = 3, b = 9/5, c = 0, and d  = 0.

Hence, our amplitude is |3| = 3.

Our period will be:

[tex]\displaystyle \text{Period}=\frac{2\pi}{9/5}=2\pi \cdot \frac{5}{9}=\frac{10\pi}{9}[/tex]

Answer:

nth term = 18 - 3n

Step-by-step explanation:

nth term = a + (n - 1)d

a1 = 15

d = -3

nth term = a + (n - 1)d

= 15 + (n - 1)-3

= 15 + (-3n + 3)

= 15 - 3n + 3

= 18 - 3n

nth term = 18 - 3n

For instance, if you want to find the 10th term

nth term = 18 - 3n

10th term = 18 - 3(10)

= 18 - 30

= -12

10th term = -12

Answer:

1 + i

Step-by-step explanation:

To rationalize multiply numerator and denominator by (2 + i )

[tex]\frac{3+i}{2-i}= \frac{3+i}{2-i} \times \frac{2+i}{2+i} = \frac{(3+i)(2+i)}{(2-i)(2+i)} = \frac{6+3i+2i-1}{4-(-1)} = \frac{5+5i}{5} = 1 + i[/tex]

Answer:

4

Step-by-step explanation:

(24+4) ÷ 2 = (24 ÷ 2) + (4 ÷ 2)

28÷2 = 14

Check:

24÷2 = 12

4÷2 = 2

12+2=14

Answer:

The answer is 4.

Step-by-step explanation:

(24 + 4) ÷ 2 = (24 ÷ 2) + (x ÷2)

=28 ÷ 2 = 12 + (x÷2)

14 = 12 + (x ÷ 2)

14 - 12 = x ÷ 2

2 = x ÷ 2

2 × 2 = x

x = 4
