To solve this with an exact answer, we would need the area of the park (size in square meters of the park). From this question, all we can solve is that, by dividing the number of ladybugs by square meters (50/10), there are 5 ladybugs per square meter, or l=5a, l being ladybugs and a being area in square meters.

1. Mrs. Nelson wants to buy a wireless speaker for her son. She has narrowed down her choice to two stores:
Oksi-84 [34.3K]

a) Mrs. Nelson will pay $45 for the speaker at Kohl's.

b) Mrs. Nelson would pay $43.70 for the speaker at Target.

c) Mrs. Nelson would get the best deal from Target's.

Step-by-step explanation:

Selling price at Kohl = $60.00

Discount coupon = 25%

Purchase price of Target = $38.00

Mark up = 15%

a.) How much would Mrs. Nelson pay for the speaker at Kohl’s?

Discount = 25% of selling price

Discount amount = \frac{25}{100}*60=\frac{1500}{100}

Discount amount = $15

Cost after discount = Selling price - Discount amount

Cost after discount = 60-15 = $45

Mrs. Nelson will pay $45 for the speaker at Kohl's.

b.) How much would Mrs. Nelson pay for this speaker at Target?

Mark up = 15% of purchase price

Mark up amount = \frac{15}{100}*38=\frac{570}{100}

Mark up amount = $5.70

Price after mark up = Purchase price + Mark up amount

Price after mark up = 38.00+5.70 = $43.70

Mrs. Nelson would pay $43.70 for the speaker at Target.

c.) Which store would Mrs. Nelson get the best deal and by how much?

Difference between prices = 45-43.70 = $1.30

Mrs. Nelson will save $15 on Kohl's and she will get the speaker at $43.70 at Target's, therefore, she would save $1.30 more if she buys speaker from Target's.

Mrs. Nelson would get the best deal from Target's.

Write the equation y=-1/2x+3 in standard form. how do I do this?
Lapatulllka [165]
Standard form is ax + by = c.  Begin our transformation by multiplying both sides by 2 to get rid of the fraction.  Notice that ax + by = c does not allow for fractions.  Doing that multiplication gives us 2y=-x + 3.  Now move the x over by the y by addition.  x + 2y = 3.  And there you go!

Which transformation maps the large triangle onto the small triangle? dilation reflection rotation translation
sweet [91]

A rotation transformation is where you turn a figure about a given point. The point about which the object is rotated can be inside the figure or anywhere outside it. There must be no change in shape or size of the object.

A reflection of an object is the 'flip' of that object over a line, called the line of reflection.

A translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized.

All these three transformations are rigid - preserve the figure sizes.

A dilation is a transformation that changes the size of a figure. It can become larger or smaller, but the shape of the figure does not change.

Answer: dilation maps the large triangle onto the small triangle
