Answer:

It's the fourth option

Step-by-step explanation:

This would make the most since the frogs and lizards have the number(18) it would make sense to chose the option that shows frogs and lizards with the same number then have worms with the smaller number

Answer:

The last option

Step-by-step explanation:

There are 42 species in the sample

the proportions are:

frogs = 18/42 = 3/7

lizards = 18/42 = 3/7

worms = 6/42 = 1/7

The number of frogs and lizards is the same and exceeds that of worms

The only option that meets these proportions is the last

Hope this helps

Determine the equation of a line in standard form that represents Kelsa’s training progress. Her progress corresponds to the poi
UkoKoshka [18]

We first get the gradient of the equation of a line by taking the change in y over change in x

Hence our gradient will be

(6-9.5)/(8-1)=-3.5/7=0.5

Taking an arbitrary point(x,y) and using our gradient we get and one of the points above we get

(y-6)/(x-8)=0.5

y-6=0.5*(x-8)

y-6=0.5x-4

y=0.5x+2 or y=1/2x+2

which is the line of our equation the answer we are asked for.

URGENT! Please Help me solve this question with the Steps
Fofino [41]

Answer:

Step-by-step explanation:

(p^{\frac{1}{2}})^3=p^{\frac{1*3}{2}}=p^\frac{3}{2}\\\\\sqrt{p^6}=p^\frac{6}{2}=p^\frac{1}{3}\\\\(p^{\frac{1}{2}})^3\sqrt{p^6}=p^\frac{3}{2}p^\frac{1}{3}=p^{\frac{3}{2}+\frac{1}{3}}=p^\frac{11}{6}

Which of the following is the measure of angle RCP?
enyata [817]

Answer:

From the information provided we have:

PD ≅ RD (= 11)

∠CPD ≅ ∠CRD (= 90°)

They both have CD as the hypotenuse.

=> ΔCPD ≅ ΔCRD

=> ∠PCD ≅ ∠RCD

Now we know that:

∠RCP = ∠PCD + ∠RCD

∠RCP = 2 · ∠RCD

∠RCP = 2 · 33° = 66°

So the answer is B

Hãy nêu định lý pytago
Natasha_Volkova [10]

The text of the Pythagorean Theorem The Pythagorean Theorem states: “The sum of the squares of the lengths of the two sides of the right triangle, which are the shortest sides in a right-angled triangle, is equal to the square of the length of the hypotenuse, which is the longest side of the triangle.”

And in symbols: Pythagorean theorem = ( A² + B² = C²)

where ;

● A, B: the two sides of a right triangle ABC.

● C: The hypotenuse of a right triangle is ABC, which is the longest side.

It should be noted that the inverse of the theory is also true; Since the triangle to which the Pythagorean theorem applies, namely: A² + B² = C², is necessarily a right-angled triangle.

<h3><u>In Vietnamese ( Bằng tiếng việt) ;</u></h3>

Nội dung của Định lý Pitago Định lý Pitago phát biểu: “Tổng bình phương độ dài hai cạnh của tam giác vuông, là cạnh ngắn nhất của tam giác vuông, bằng bình phương độ dài của cạnh huyền, là cạnh dài nhất của tam giác. "

Và trong các ký hiệu: Định lý Pitago = (A² + B² = C²)

ở đâu ;

● A, B: hai cạnh của tam giác vuông ABC.

● C: Cạnh huyền của tam giác vuông ABC là cạnh dài nhất.

Cần lưu ý rằng điều ngược lại của lý thuyết cũng đúng; Vì tam giác áp dụng định lý Pitago, cụ thể là: A² + B² = C², nhất thiết phải là tam giác vuông.

I hope I helped you^_^
