Simon bought three plants at a nursery for $17.94. How much money would it cost for Simon to go back to the store and buy two more plants?
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
What is a cost?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

Jerry is making an investment, from which he wants to make a certain amount of interest.

A. 1= ? RE ili ITE B. 1= € hilli C. (=1-P- r D. r=T +P +7
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]

SASΔRTS ≅ ΔRTUStep-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 ...

Point T is on line segment \overline{SU} SU . Given TU=x-1,TU=x−1, SU=3x-7,SU=3x−7, and ST=x+7,ST=x+7, determine the numerical length of \overline{TU}. TU .
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

Select the correct answer.
The perimeter of a triangle is 30 units. If it is dilated with respect to origin by a scale factor of 0.5, what is the perimeter of the resulting triangle?
A. 30 units
B. 20 units
C. 15 units
D. 7.5 units
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.
What is dilation?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.

Sam's rectangular garden measures 1 1 5 1 1 5 yards by 2 5 6 2 5 6 yards. His neighbor, Tess, has a rectangular garden that is 8 1 2 8 1 2 yards long and has a perimeter of 33 yards. What is the ratio of the area of Sam's garden to the area of Tess's garden?
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

1) Determine Domain of graph below in interval notation
A.D=[-5,5] B.D=[-5,5) C.D=(-5,5) D.D=(-5,5]
2) Determine Range of graph below in set builder notation
Answer: 1) D 2) B, A 3) A
Step-by-step explanation:
Domain is the x-values
Range is the y-values
Graph is a function if no x-values are duplicated
1) option D
(3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)
↓ ↓ ↓ ↓ ↓
Domain: x = {1, 1, 8, -4, 2} → No duplicates so it is a function.
(3, 7), (1, 0), (8, 1), (-4, -3), (2, 7)
↓ ↓ ↓ ↓ ↓
Range: y = {7, 0, 1, -3} 7 is a duplicate so only needs to be listed once
2) Domain = option B, Range = option A
x-values are between -5 (included = bracket) and +5 (not included = parentheses)
y-values are between -5 (included = bracket) and +5 (included = bracket)
3) option A
Domain: x = {1, 4, 5, 7, 9} → 4 matches to both 5 and 7 so is NOT a function
Range: y = {3, 5, 7, 8}

|2x+3|-5<12
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
