Answer:

T = 5 (H = 7, M = 1); T = 7 (H = 4, M = 2); T = 9 (H = 1, M = 3)

Step-by-step explanation:

We know MH+MH+MH=TM

MH is a two digit number, and TM is also a two digit number.

MH+MH+MH=3*(MH)<100

3M<=9, meaning that M could be 1, 2, or 3.

If M=1, MH+MH+MH=3(10+H)=30+3H=TM=10*T+1

30+3H=10T+1, so 3H must include 1 in one's digit.

The only possibility is that 3H = 21, then H = 7

MH+MH+MH=17+17+17=TM=51, T = 5

If M=2, MH+MH+MH=3(20+H)=60+3H=TM=10T+2

60+3H=10T+2, so 3H must include 2 in one's digit.

The only possibility is 3H = 12, then H = 4

MH+MH+MH=24+24+24=72, T = 7

If M=3, MH+MH+MH=3(30+H)=90+3H=TM=10T+3

90+3H=10T+3, so 3H must include 3 in one's digit.

The only possibility is 3H = 3, then H =1

MH+MH+MH=31+31+31=93, T=9

We will see that if we define M = 2, and H = 4, the value that T takes is T = 7

We know that:

MH + MH + MH = TM

We can write this as:

M*10 + H + M*10 + H + M*10 + H = T*10 + M

30*M + 3*H = T*10 + M

30*M - M + 3*H = T*10

(29*M + 3*H)/10 = T

Now we need to find two values for M and H such that T is a digit.

For example, if M = 2 we have:

(29*2 + 3*H)/10 = T

(58 + 3*H)/10 = T

Now we can take H = 4, then we get:

(58 + 3*4)/10 = T

(58 + 12)/10 = T = 7

In this case, we found that a possible value of T is T = 7.

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid =   x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid

Answer:

  583.4 cm³

Step-by-step explanation:

We have the base dimensions, so enough information to find its area:

  A = s²

  A = (10 cm)² = 100 cm²

__

The height of the triangle is found by solving triangle AMV for the distance MV. That is found from the trig relation ...

  Tan = Opposite/Adjacent

  tan(68°) = MV/AM

The length of AM is half the diagonal of the square base, so is (10√2)/2 = 5√2. The length of MV is ...

  MV = AM·tan(68°) = 5√2·tan(68°) ≈ 17.50

So, the volume of the pyramid is ...

  V = (1/3)Bh

  V = (1/3)(100 cm²)(17.50 cm) ≈ 583.4 cm³ . . . . volume of the pyramid

Answer:

Solution given:

For finished box

length[L]=36-4-4=28in

breadth [b]=36-4-4=28in

height[h]=4in

Now

volume of square box=l×b×h=28*28*4=3136in³

1.

the volume of finished box is 3136in³

2.

if we change the 4 inches into different measurement ,its maximum or largest volume is 3136in³.

As volume is constant.

The volume of the box will be 3136 cu. unit and the largest volume the box can be made of is also the same.

The amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters)

The given square after getting folded turns into a box of 28*28*4 inches

The volume of the box can be detrmined by using the formula of volume of the cuboid.

Volume of the cuboid = 28*28*4

=3136 cu.inches

The largest volume that the box can have is 3136 as when increasing the height the length or the width will decrease and so does the volume.

Answer:

y = -5x + 14

Step-by-step explanation:

Parallel lines have the same slope, and their equations are identical except for the value of the constant (which in turn is the y-intercept).

Both lines have the slope m = -5.  Start with y = mx + b, or y = -5x + b.  Then substitute 3 for x and -1 for y:

-1 = -5(3) + b, or:

14 = b (the y-intercept is 14)

Then the desired equation is y = -5x + 14.

Answer:

The second deal is better. It is $2.042 per gallon

Step-by-step explanation:

$11/5 and 51.05/25 are the deals.

Let's multiply the first deal by 5/5.

That is $55 per 25 gallons and the other deal is $51.05 per 25 gallons.

So the second deal is better.

Now lets divide 51.05 by 25 to find out how much dollars per gallon

51.05 / 25 = 2.042, so it is $2.042 per gallon.

Answer:

y = 12

Step-by-step explanation:

The segments are equal in length, SR = TR, so set up an equation:

[tex]\frac{y^2}{12}=y[/tex]

Multiply by 12.

[tex]y^2=12y\\y^2-12y=0[/tex]

Factor out the y on the left side.

[tex]y(y-12)=0[/tex]

There are two solutions:  y = 0 and y = 12.  The y = 0 solution makes no sence (segment SR can't have a length of 0).  The other solution, y = 12, works just fine.
