Answer:

732π cm^3

Step-by-step explanation:

Volume of the biggest cone

(15^2 * π *20)/3 = 1500π cm^3

Volume of the smallest cone

20^3 : 16^3= 1500π : x

x = (1500π * 4096)/8000= 768π cm^3

Volume of the frustum = 1500π - 768π = 732π cm^3

James gave Robert half a candy bar. Robert gave his sister half of what he had. What fraction of the whole candy bar did Robert
Evgesh-ka [11]

Answer:

1/4

25%

Step-by-step explanation:

Robert has 1/2 of the candy bar

If he gave his sister half, she has 1/2 x 1/2 = 1/4 of the candy bar

To convert 1/4 to percentage, multiply by 100

1/4 x 100 = 25%

<span>To acquire knowledge, thought is a fundamental necessity -It must be "thought about" before any new ideas can be formulated (e.g., a student who is learning English as a second language must be competent in his primary native language before he can "think" or understand new concepts in another language) -Initial emergence of language and thought are separate from each other, until about the age of 3 when a transition takes place in the child from the external to the internal -Children practice private speech (self-talk) to become more competent ---The use of private speech helps children to self-regulate through organizing, guiding, and controlling their behavior ---Private speech is responsible for all higher levels of mental functioning Noam Chomsky Language Acquisition -Language learning is innate -Chomsky believes that children are prewired to learn language and that infants have a language acquisition device (LAD) built-in neurologically so that they can intuitively understand grammar -There is a critical period when children find it easy to learn language Language development milestones: Infant (0-12 months) -Early vocalizations are spontaneous sounds of cooing (vowels) or crying -Then babbling sounds (phonemes) begin with sounds more like patterned speech with consonant-vowel strings ("da-da-da-da")</span>

AB and DE are chords that intersect at point F inside circle C as shown. If the measure of arc EA= 50 degrees and the measure of
defon

Answer:

Part 1) m\angle AFE=55^o

Part 2) m\angle EFB=125^o

Step-by-step explanation:

Part 1) what is the measure of angle AFE

we know that

The measure of the interior angle is the semisum of the arches that comprise it and its opposite.

<u>Note:</u> In this problem the correct measure of arc EA is 40 degrees (see the picture)

so

m\angle AFE=\frac{1}{2}(arc\ EA+arc\ DB)

substitute the given values

m\angle AFE=\frac{1}{2}(40^o+70^o)=55^o

Part 2) what is the measure of angle  EFB?

we know that

m\angle AFE+m\angle EFB=180^o ---> by supplementary angles (form a linear pair)

so

substitute the given value

55^o+m\angle EFB=180^o

m\angle EFB=180^o-55^o=125^o

Gregor Mendel is examining peas to try to understand how traits are passed from parents to offspring. Today, Gregor has 228 peas
Alina [70]

Answer:

38 pods

Step-by-step explanation:

To find about what this is, divide 228 by 6.

What is the nearest multiple of 60 to 228 without going over?

228 - 180 = 48

What it the nearest multiple of 6 to 48 without going over?

48 - 48 = 0

180 = 6 * 30

48 = 6 * 8

30 + 8 = 38 pods
