Answer:

50.6

Step-by-step explanation:

MA=46.2-14=32.2

We have similar triangles.

That is, triangle MNP is similar to MAB.

This means, we have the following proportion to solve:

32.2/46.2=x/72.6

Multiply both sides by 72.6

32.2/46.2*72.6=x

50.6=x

This is a rectangular prism,

Here length = 16 m

Width = 6 m

Height = 3 m

Surface area of rectangular prism = 2( bl + lh + hb )

Where,

b – base length of the rectangular prism.

l – base width of the rectangular prism.

h – height of the rectangular prism.

Putting these values, surface area = 2(16×6 + 16×3+ 3×6)

= 2( 96+48+18) = 2×162 = 324m

hope you get it well :)

Step-by-step explanation:

The number of hardcover books will be 3,4, and 8.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Tim is sorting his book collection into groups. He places each group onto bookshelves that can each hold a maximum of 25 pounds. His collection includes hardcover books that weigh 3 pounds each and softcover books that weigh 2 pounds each.

Total weight = 25 pounds

The number of hardcover books which weigh less than 25 pounds is,

3 x 3 pounds = 9 pounds

4 x 3 pounds = 12 pounds

8 x 3 pounds =- 24 pounds

Therefore, the number of hardcover books will be 3,4, and 8.

Answer:

the answer to number one is 18.5. i'm not sure about two or three, sorry.

Step-by-step explanation:

1. I think you can use the formula for speed:

speed = distance / time

2. Transpose the equation to find distance and you'll get:

distance = speed x time

3. Substitute the given inputs...

distance = (40 m/s)(0.4625s)

4. Cancel "s".

distance = (40m)(.4625)

5. Calculate.

distance  = 18.5 m  -- ANSWER

1) The distance be 18.5 meter.

The Velocity of ball is v = 40.0 m/s and it taking t = 0.4625 seconds to arrive at home plate.

What is the relation between velocity, distance and time?

Velocity equals distance travelled divided by the time it takes to get there.

Now,

Velocity = distance/ time

So, Distance = time x velocity

⇒ Distance = 0.4625 x 40.0

                     = 18.5 m

Thus, the distance be 18.5 meter.

2) Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].

Here, Speed of radio signal is 300,000 km/s

         Time taking in travel is 80 second.

Speed = distance/ time

Distance = speed x time

              = 300,000 x 80

              = 24,000,000

Hence, Distance of the signal travel is [tex]24 *10^{6}[/tex] [tex]km/sec^{2}[/tex].

3) Time taking to elapses before it strikes a target is 4.06 second.

Here, Speed of bullet is 1230 m/s

        Distance travel by bullet is 5000m

Now,

Speed = distance/ time

Time = distance / speed

        = 5000/1230

        = 4.06 second

Hence,

Time taking to elapses before it strikes a target is 4.06 second.

Step-by-step explanation:

Use the slope formula when given two points

Slope formula = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

( the x and y values are determined by the given points )

Given the points ( 0 , 5 ) and ( 1 , 3 )

Plug in the x and y values of the given points into the formula

( remember y values on top x values on bottom )

[tex]slope=\frac{5-3}{0-1} \\5-3=2\\0-1=-1\\slope=\frac{2}{-1} =-2[/tex]

Answer:

[tex]P = [-3/5,2.33][/tex]

Step-by-step explanation:

Given

See attachment for line segment RQ

[tex]P = \frac{5}{6}[/tex] of RQ

Required

The coordinates of P

Using line segment ratio formula, we have:

[tex]P = [\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n}][/tex]

If P is at:

[tex]P = \frac{5}{6}[/tex]

Then:

[tex]m : n = \frac{5}{6} : 1 -\frac{5}{6}[/tex]

Solve

[tex]m : n = \frac{5}{6} : \frac{6-5}{6}[/tex]

[tex]m : n = \frac{5}{6} : \frac{1}{6}[/tex]

Multiply by 6

[tex]m : n = \frac{5}{6} *6: \frac{1}{6} * 6[/tex]

[tex]m : n = 5 : 1[/tex]

By comparison

[tex]m=5\ \& n = 1[/tex]

From the attached line segment

[tex]R(x_1,y_1) = (4,-1)[/tex]

[tex]Q(x_2,y_2) = (-5,3)[/tex]

So, we have:

[tex]P = [\frac{5*-5 + 1*4}{5+1},\frac{5*3 + 1*-1}{5+1}][/tex]

[tex]P = [\frac{-25 + 4}{6},\frac{15 -1}{6}][/tex]

[tex]P = [\frac{-21}{6},\frac{14}{6}][/tex]

[tex]P = [-3/5,2.33][/tex]

Answer:

Step-by-step explanation:

Answer:

43in

Step-by-step explanation:

Let the length of the pieces be x and y

Since the total length is 258in, then;

x+y = 258... 1

If One piece is five times the length of the other, then x = 5y ....2

Substitute 2 into 1

From 1:

x+y = 258

5y+y = 258

6y = 258

y = 258/6

y = 43

Since x = 258-y

x = 258-43

x = 215

Hence the length of the shorter piece is 43in
