Step-by-step explanation:

Answer: 10,488 cu. in.

Step-by-step explanation:

Volume of rectangular prism = l x w x h

= 16 x 18 x 23 = 6624 cu. in

Volumr of triangular prism = 1/2bh (height of prism)

= 1/2 x 23 x 21 x 16

= 3864 cu. in.

Volume of the figure = 6624 + 3864 = 10,488 cu. in

Answer:

AM = 26

Step-by-step explanation:

AM = MC

x+20 = 5x-4

Subtract x from each side

x+20-x = 5x-x-4

20 = 4x-4

Add 4 to each side

20+4 = 4x-4+4

24 = 4x

Divide by 4

24/4 = 4x/4

6 =x

We want AM

AM = x+20

       =6+20

      =26

Answer:

26

Step-by-step explanation:

x+20=5x-4

x+24=5x

24=4x

x=6

x+20

substitute 6 for x

6+20

26

the third option is your answer

Step-by-step explanation:

[tex]\frac{5}{a-3}+\frac{3}{a+3}\\\mathrm{Least\:Common\:Multiplier\:of\:}a-3,\:a+3:\quad \left(a-3\right)\left(a+3\right)\\\mathrm{Adjust\:Fractions\:based\:on\:the\:LCM}\\=\frac{5\left(a+3\right)}{\left(a-3\right)\left(a+3\right)}+\frac{3\left(a-3\right)}{\left(a+3\right)\left(a-3\right)}\\\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}\\=\frac{5\left(a+3\right)+3\left(a-3\right)}{\left(a-3\right)\left(a+3\right)}[/tex]

Answer:

70°

Step-by-step explanation:

By inscribed angle theorem:

[tex] 95° = \frac{1}{2}(c + 120°)\\\\

\therefore 95°\times 2 = c + 120°\\\\

\therefore 190° = c + 120°\\\\

\therefore c = 190° - 120°\\\\

\huge \orange {\boxed {\therefore c = 70°}} [/tex]

Answer:

To find the scale factor, we simply create a ratio of the lengths of two corresponding sides of two polygons. If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.

Answer:

The question is asking to choose among the following choices that states the equation that is not necessarily true about the said coordinate plane and in my further calculation, the answer would be G'H' = 8 units.

( I think you made a mistake when writing the answer choice for B, because the correct answer is G'H' = 8 units )

Anyways, Hope this helps!

Answer: B

Step-by-step explanation:

Answer:

Yes!

Step-by-step explanation:

When we have problems like this we just plug them in. We take the -2 and we multiply it by the -5 to get a positive 10. We then add that to the +13 and it equals 23, so it works!

Step-by-step explanation:

Total marbles = 2 + 4 +1 + 8 = 15 marbles

Probability of blue marble = 4 / 15

Probability of green marble = 2 / 15

Answer:

4/105

Step-by-step explanation:

Total number of marbles: 2 + 4 + 1 + 8 = 15

Number of blue marbles: 4

First drawing:

p(blue marble) = 4/15

Now there are 14 marbles left.

Number of green marbles: 2

p(green marble) = 2/14 = 1/7

p(blue then green) = p(blue) * p(green) = 4/15 * 1/7 = 4/105

Answer: 4/105

Depending on how much chicken salad can be purchased for $0.50, you multiply that number by $52.50/0.50.

Step-by-step explanation:

Answer:

Step-by-step explanation:

In general ,A linear function has the form y = ax + b

so ,the functions :

y = √x

y = x²

y = x³

don’t meet the requirements of the definition

therefore none of them is linear.

but y = x is a valid choice (just put a = 1 and b = 0  in the expression y = ax + b)

Answer:

126 in^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) h

A = 1/2 ( 12+16)*9

A = 1/2 (28) *9

  = 126

Answer:

126 ^2 in

(12)+(16)/2 * (9)

Area= a+b/s(h)

Step-by-step explanation:

Answer:

747  people per square mile

Step-by-step explanation:

population of  city's town hall = 150,000

Radius of  city's town hall = 8 mile

area of any circular shape is given by [tex]\pi r^2[/tex].

r is the radius of circle.

p

Area of city's town hall = [tex]\pi r^2= 3.12*8^2 = 3.14*64 = 200.96[/tex]

Population density for any place is ratio of population of that place to area of that place

Thus

Population density for city's town hall = population of  city's town hall /Area of city's town hall

Population density for city's town hall =  150,000/200.96

Population density for city's town hall= 746.42  people per square mile.

Population density for city's town hall  Rounded  to the nearest whole number is 747  people per square mile.

Answer:

2

Step-by-step explanation:

We can find the slope by

m = (y2-y1)/(x2-x1)

    = (4-2)/(-1 - -2)

    = (4-2)/( -1 +2)

    =2/1

   = 2

Answer:

2

Step-by-step explanation:

slope= [tex] \frac{y1 - y2}{x1 - x2} [/tex]

Thus, slope of the line

[tex] = \frac{4 - 2}{ - 1 - ( - 2)} \\ = \frac{2}{2 - 1} \\ = \frac{2}{1} \\ = 2[/tex]

Answer:

  5.  A) two solutions

  6.   one solution

Step-by-step explanation:

5. A graph shows the curve has two x-intercepts, so two solutions. You can also figure this by looking at the discriminant:

  b^2 -4ac = (7)^2 -4(-4)(8) . . . . a positive number

When the discriminant is positive, there are two real solutions.

__

6. The equation factors as ...

  0 = 3(x +3)^2

This will have one real solution at x=-3.

Answer

The product of the two factors with be a multiple of the first factor. That is, the product when divided by the first factor, will result in zero as the remainder. In this case, the product is 16/55 which is a multiple of 4/5.

Answer:

Please check the attached picture

Step-by-step explanation:

In the first row, there are 5 players in total, 4 of them practice extra time, then 5 - 4 = 1 player does not practice extra time.

In the second row, there are 5 players in total, 2 of them practice extra time, then 5 - 2 = 3 players do not practice extra time.

In the third row, there are 8 players in total, 2 of them practice extra time, then 8 - 2 = 6 players do not practice extra time.

We finally add up each column, to complete the table.

I hope this helps!

Answer:

the first one

Step-by-step explanation:

Since x can be any value, -infinity must be less than x because you can always subtract 1 from x. Also, infinity must be more than x because you can always add 1 to x.

Answer: A

Step-by-step explanation:

This problem, may seem abit tricky, but this sequence is all about plugging in.

Since c₁=5, we can solve for c₂ and c₃.

c₂=c₁·2ⁿ⁻¹

c₂=5·2¹

c₂=10

Now that we have c₂, we can find c₃.

c₃=c₂·2ⁿ⁻¹

c₃=10·2²

c₃=40
