Step-by-step explanation: Hope this help :D

Answer: Yes

Step-by-step explanation:

a right triangle is ... 9, 12, 15, 40, 41. 10, 24, 26. 12, 16, 12, 35, 37. 14, 48, 50. 15, 20, 25. 15, 36, 39. 16, 30, 34. 18, 24,  21, 29, 28, 35, 32, 40. 27, 36, 45. 40, 50

Answer:

The bases are congruent

Step-by-step explanation:

From the question, we understand that the top base and the bottom base are directly opposite one another.

When such a scenario arise, it means that the bases have the same shape, they have the same dimension (i.e. size).

With the above analysis, we can conclude that the bases are congruent.

However, the given information can not be used to determine the shape and congruence of the lateral faces.

Lastly, for the bases to be congruent, they must have the same shape (and not any shape).

Hence, only option (b) is correct

Answer:

3$

Step-by-step explanation:

Let x be t-shirts and y socks.

4x + 3y= $37

2y + 5x= $41

x= (37 - 3y) ÷ 4

2y + 5((37-3y)÷4)=41

y=3

Answer:

a=11

Step-by-step explanation:

set the formula up as

22+7a = 9a

22 = 9a - 7a

22 = 2a

22/2 = a

11 = a

Answer: 875 people

Step-by-step explanation:

The 375 people seated represent 30% of the total number of people who wanted seats but these ones got them.

This means that the number of people who wanted seats is 70% of the number of people who wanted seats.

Assume the number of people who wanted seats is x:

30% * x = 375

x = 375 / 30%

x = 1,250 people wanted seats.

Those who wanted seats but couldn't get:

= 1,250 * 70%

= 875 people

Answer:

x = 81

Step-by-step explanation:

180 (62 + 37) = x

81 = x

Hope this helps!

Answer:

81

Step-by-step explanation:

x + 37 + 62 = 180

x + 99 = 180

x = 180 - 99

x = 81

Answer:

1.7

Step-by-step explanation:

Adding together all the points, you get 10. 10 divided by 7 is 1.666666667, which rounds to 1.7

Answer: Approximately 28 km

The more accurate, yet still approximate value, is roughly 27.995735464379

Round that however you need to.

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

Explanation:

As the diagram shows, the uppercase letters A,B,C represent the corner points of the triangle. They also represent the angles. The diagram says that:

The missing angle C is....

A+B+C = 180

C = 180-A-B

C = 180-59-91

C = 30

which we'll use later.

Convention usually has the side lengths be lowercase letters 'a', b, and c. Those lowercase letters are opposite their uppercase counterpart. We'll have side 'a' opposite angle A, then b is opposite B, and c is opposite C. This allows us to quickly label a triangle and find the missing sides and/or angles. The phrasing "solve the triangle" basically means "find all the missing sides and angles". For this problem, we're only concerned with one side.

The diagram says that side c = 14 due to it being opposite angle C.

The goal is to find side b, which is the shorter way of saying "find AC".

-------------------------

From here, we can use the law of sines to find side b

b/sin(B) = c/sin(C)

b/sin(91) = 14/sin(30)

b = sin(91)*14/sin(30)

b = 27.995735464379 which is approximate

b = 28

Side AC is roughly 28 km long.

I rounded to the nearest whole number since the "14 km" is also a whole number. Your teacher may want you to round differently.

Make sure your calculator is in degree mode.

Answer:

D   y = 2x + 2

Step-by-step explanation:

Set the equations equal

2x -1 = 2x + 2

Subtract 2x from both sides

-1 = 2 ... not possible

therefor no solution

there is no solution.

Answer:

P (x>5) = 0.5324014=0.523

Step-by-step explanation:

Here success = p= 0.7 and failure = q= 1-p= 1-0.7 = 0.3

Number of surgeries= n= 8

Applying the binomial distribution

( p+q) ^n= nC x p^x . q^n-x

More than 5 means  6,7, and 8

( p+q) ^8= 8C 5 (0.7)^5 . (0.3)^3

                =56* 0.16807*0.027

                       = 0.254121

( p+q) ^8= 8C 6 (0.7)^6 . (0.3)^2

                =  28* 0.1177* 0.09

                    = 0.296604

( p+q) ^8= 8C 7 (0.7)^7 . (0.3)^1

                =  8* 0.0824* 0.3

                  = 0.19776

( p+q) ^8= 8C8 (0.7)^8 . (0.3)^0

                =  1* 0.05765* 1

                  =0.05765

Adding the above all probabilities  gives

P (x>5) = P (x=6) + P(x=7) + P(x=8)

               = 0.296604+0.19776+0.05765

                   = 0.5324014

Given:

The quadratic equation is:

[tex]10m^2-7m+3=0[/tex]

To find:

The solutions for the given equation by using the quadratic formula.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]10m^2-7m+3=0[/tex]

Here, [tex]a=10,b=-7,c=3[/tex]. Using the quadratic formula, we get

[tex]m=\dfrac{-(-7)\pm \sqrt{(-7)^2-4(10)(3)}}{2(10)}[/tex]

[tex]m=\dfrac{7\pm \sqrt{49-120}}{20}[/tex]

[tex]m=\dfrac{7\pm \sqrt{-71}}{20}[/tex]

[tex]m=\dfrac{7\pm i\sqrt{71}}{20}[/tex]             [tex][\because \sqrt{-a}=i\sqrt{a},a>0][/tex]

Therefore, the solution set of the given equation is [tex]\left\{\dfrac{7- i\sqrt{71}}{20},\dfrac{7+ i\sqrt{71}}{20}\right\}[/tex]. Hence, the correct option is D.

Answer:

can you tell me a little bit more?

Answer:

30

Step-by-step explanation:

Step 1: Find the area of the whole figure

The whole figure is a rectangle with a width of 4cm and a length of 12cm

The area of a rectangle can simply be calculated by multiplying the width by the length

So area = 4 * 12 which = 48

So the area of the whole figure is 48cm²

Step 2: Find the area of the non shaded area

The non shaded area forms a triangle with a base length of 9cm and a height of 4cm

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height

That being said we plug in the values into the formula

[tex]A=\frac{9*4}{2} \\9*4=36\\\frac{36}{2} =18[/tex]

Hence the area of the non shaded region is 18cm²

Final step: Our last step is to subtract the area of the non shaded region by the area of the whole figure

so the answer = 48 - 18 which equals 30

Hence the area of the shaded region is 30 square centimeters.
