James is a botanist studying the production of beans by two types of bean plants.
He noticed that the string bean plant produced 30% more beans than the lima bean
plants. Based on James' observation, if the string bean plants produced 130 string
beans, how many lima beans did the lima bean plant produce?

Answers

Answer:

100 lima beans

Step-by-step explanation:

We can write an equation with s = string beans and l = lima beans:

s = 1.3l

We can now plug in 130 = s to get:

130 = 1.3l

We divide both sides by 1.3 and get:

100 = l

That means the lima bean plant produced 100 lima beans

Answer:

Step-by-step explanation:

130 * 30% =

130 * 0.3 =

130 - 39 = 91

Order these numbers from least to greatest.

A group of students are going on a trip and the trip costs $36.50 per student which includes $9.50 for lunch, an entrance ticket and a gift coupon. The gift coupon costs $50 for the entrance ticket. The cost of an entrance ticket is

A) $27.00
B) $25.00
C) $18.00
D) $13.50

Answers

The answer is D) $13.50

Step-by-step explanation:

So first what you're gonna do it subtract $9.50 from $36.50 which will get you to $27.00.

Then you'll have to figure out what half of $27.00 is.

That will get you to the answer of D) $13.50

Which equation shows how (-10,8) can be used to write the equation of this line in point-slope from?

Answers

Options :

y – 8 = –0.15(x – 10)

y + 8 = –0.15(x – 10)

y – 8 = –0.2(x + 10)

y + 8 = –0.2(x – 10)

Answer:

y – 8 = –0.2(x + 10)

Step-by-step explanation:

(-10, 8)

General equation in point - slope form:

y - y1 = m(x - x1)

m = slope

Given the points : ( - 10, 8)

x1= - 10 ; y1 = 8

y - y1 = m(x - x1)

Substitute the values of x and y into the equation :

y - 8 = m(x - - 10)

y - 8 = m(x + 10)

The best option which fits is :

y – 8 = –0.2(x + 10)

A) AA similarity

Step-by-step explanation:

AA stands for "angle, angle" and means that the triangles have two of their angles equal.

SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides and we we also know the included angles are equal.

SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.

Here we can easily see that two angles are equal

∠CYK and ∠KZP∠CKY and ∠PKZ (they're cross angles)

Therefore it's AA similarity
