Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You can get $20 per day for helping your neighbor rake lawns. After how many days will your sister earn as much as you?

Answers

Answer 1

Answer:

6 days

Step-by-step explanation:

pay 60 = -60

Let d = the number of days

30d - 60 = sister

20d = me

Equation:

30d - 60 = 20d                    Move 30 to the other side

-30d          -30d

-60 = 20d - 30d                    Combine liked terms

-60 = -10d                                

-10     -10                                Divide

d = 6

Write the component form of the vector that translates P(4,5) to P'(-3,7)

Answers

Answer:

The component form of the vector is v = -7·i + 2·j

Step-by-step explanation:

The given parameters are;

The coordinates of the initial point = P(4, 5)

The coordinates of the point after the translation by the vector, v = P'(-3, 7)

Therefore, we have;

The horizontal component of the vector, vₓ = (-3) - 4 = -7

The vertical component of the vector, [tex]v_y[/tex] = 7 - 5 = 2

The magnitude of the translation, v = √([tex]v_y[/tex]² + vₓ²) = √((-7)² + 2²) = √53 ≈ 7.28

Therefore, the component form of the vector, v, is given as follows;

v = vₓ·i + [tex]v_y[/tex]·j

Substituting the known values of vₓ and [tex]v_y[/tex] gives;

v = -7·i + 2·j

The component form of the vector is v = -7·i + 2·j.

Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.

Quadrilateral A B C D is translated down and to the left to form quadrilateral O L M N.

If AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units, what is LO?

5 units
6 units
8 units
10 units

Answers

Answer:

LO = 6 units ⇒ B

Step-by-step explanation:

Translation does not change the size or the shape of the figure

∵ Quadrilateral ABCD is translated down and left to form

   quadrilateral OLMN

The image of side AB is side OL

∴ The image of side BC is side LM

∴ The image of side CD is side MN

∴ The image of side AD is side ON

AB = 6 units

∵ Translation does not change the size of the figure

∴ The image of AB = 6 units

∵ The image of AB is OL

∴ The length of OL = 6 units

∵ OL = LO

LO = 6 units

The length of LO of the newly translated quadrilateral is; Option B: LO = 6 units.

Translation of objects in mathematics simply means to move an object from one point to another without a change of length or figure.

Now we are told that Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.

Thus means Quadrilateral OLMN is still same size and length as ABCD and as such the sides will correspond in order.

Thus, it means that;

AB = OL

BC = LM

CD = MN

AD = ON

We are given;AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units

Thus, since AB = OL, we can say that;

LO = 6 units.

Use a proportion to find the missing side length in the following similar figures. Please help me understand and figure out how to solve this question. Thank You! :)

Answers

Answer:

x = 4.5 m ⇒ A

Step-by-step explanation:

The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal

In the given figure

∵ The two triangles are similar

2 m and x are corresponding sides

4 m and 9 m are corresponding sides

∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]

→ By using cross multiplication

x × 4 = 2 × 9

∴ 4x = 18

→ Divide both sides by 4 to find x

∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]
