Answer:

15 unites

Step-by-step explanation:

Given:

perimeter = 30 units

scale factor = 0.5

30 units * 0.50 = 15 units

The perimeter of the resulting triangle is 15 units.

The perimeter of the dilated triangle will be, 15 units.

Dilation means changing the size of an object without changing its shape.

Given that, The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5, we need to find the perimeter of the resulting triangle,

Since, the triangle is with respect to origin by a scale factor of 0.5,

Therefore, the perimeter of the original triangle will be reduced by 0.5 units,

The perimeter of dilated triangle = 30 x 0.5 = 15

Hence, the perimeter of the dilated triangle will be, 15 units.

Answer:

3.4 : 104.125

Step-by-step explanation:

Sam's rectangular garden measures 1 1 /5 yards by 2 5 /6yards.

Area of Sam's garden = Length × Breadth

= 1 1/5 × 2 5/6

= 3 2/5 square yards

= 3. 4 square yards

His neighbor, Tess, has a rectangular garden that is 8 1 /2yards long and has a perimeter of 33 yards.

Perimeter = 2L + 2 W

2W = P - 2L

W = P - 2L/2

W = 33 - 8 1/2/2

W = 49/2 ÷ 2

W = 12 1/4 yards

Area of Tess Garden = Length × Width

12 1/4 × 8 1/2

= 104 1/8 square yards

= 104 .125 square yards

What is the ratio of the area of Sam's garden to the area of Tess's garden?

= Sam : Tess

= 3.4 : 104.125

Answer:

[tex]T = \frac{I}{PR}[/tex]

Step-by-step explanation:

Given

[tex]I = PRT[/tex]

What the question implies is that, we make T the subject of formula.

In other words, solve for T

We have that:

[tex]I = PRT[/tex]

Divide both sides by PR

[tex]\frac{I}{PR} = \frac{PRT}{PR}[/tex]

[tex]\frac{I}{PR} = T[/tex]

Reorder

[tex]T = \frac{I}{PR}[/tex]

Answer:

TU = 12 units

Step-by-step explanation:

Given that T is a point on line segment SU.

So that;

SU = ST + TU

But, SU = 3x - 7, TU = x - 1, and ST = x + 7.Thus,

SU = ST + TU

3x - 7 = (x + 7) + (x - 1)

3x - 7  = x + 7 + x - 1

3x - 7 = 2x + 6

Collecting like terms.

3x - 2x = 6 + 7

x = 13

Therefore,

TU = x - 1

    = 13 - 1

   = 12

TU = 12 units

ST = x + 7

    = 13 + 7

   = 20 units

SU = 20 + 12

     = 32 units

Answer:

x=4

Step-by-step explanation:

Add six to both sides

x/4=1

Multiply by 4 on both sides

x=4

Regroup.

x/4 - 6 = -5

Add 6 to both sides

x/4 = -5 + 6

Simplify

x/4 = 1

Solve for x

x = 1×4

x = 4

Answer:

-2q+5, choice a

Step-by-step explanation:

Answer:

- 10 < x < 7

Step-by-step explanation:

Inequalities of the type | x | < a

Always have solutions of the form

- a < x < a

Given

| 2x + 3 | - 5 < 12 ( add 5 to both sides )

| 2x + 3 | < 17 , then

- 17 < 2x + 3 < 17 ( subtract 3 from all 3 intervals )

- 20 < 2x < 14 ( divide the 3 intervals by 2 )

- 10 < x < 7

Answer:29.4

Step-by-step explanation:

alright so basically if he bought 3 plants for 17.94, then you just have to divide by three, like so. 17.94/3. you can do this with any calculator. now you have the original price of each plant, which is $5.98. now, multiply by two. $11.96. now add 17.94. $29.4.  that is the final answer

The cost of buying two more plants is $11.98

Cost is a value of money that a company had to spend to produce its goods or services.

Given that, Simon bought three plants at a nursery for $17.94

Cost of 3 plants = $17.94

Cost of 1 plant = $17.94/3

Cost of 1 plant = $5.98

Cost of 2 plant = $5.98*2 = $11.96

Hence, The cost of buying two more plants is $11.98

Answer:

Step-by-step explanation:

The two triangles share a side, so that side will be both corresponding (to itself) and congruent (to itself). The two marked sides are congruent, as are the angles at the point of intersection (T) between the shared side and the marked sides.

So, we have congruent sides with a congruent angle between them. The SAS theorem applies to this situation. As we noted, side RT corresponds to itself. The third vertices of each triangle also correspond, so the congruence statement can be written ...
