How does the volume of a sphere with radius 2cm compare to the volume of a sphere with radius 1cm

1 answer:

5 0

if you take the radius of the first and second sphere you find that they are doubled there fore the volume changed at a rate of 2 squared because 2 is what the radius was multiplied by going from the second sphere to the first so you would square what the sphere was multiplied by there fore making your answer: the volume is compares with 2 squared

In a genetics experiment on peas, one sample of offspring contained 376green peas and 150yellow peas. Based on those results,

ivanzaharov [21]

Answer:

1a. p0= 0.714

1b The result is not reasonably close to the value of 3/4 that was expected

Step-by-step explanation:

1a.Since One sample of offspring contained 376 green peas and 150 yellow peas therefore the probability of getting an offspring pea that is green will be:

Green pea/(Green pea+ Yellow pea)

p0= 376 /(376+150)

p0=376/526

Probability of getting Green pea = 0.714

1b.The result is not reasonably close to the value of 3/4 that was expected.

Is the following relation a function? X Y 6 -1 -1 2 4 3 0 3

german

Answer: Given relation is a function

A relation is said to be a function if no value in its domain is paired up with more than one value in its range.

Since x values represent the Domain of a relation and y values represent the Range of a relation, in terms of x and y we can say:

A relation is said to be a function if an x-value is not paired up with more than one y-value.

From the above table we can see that all the x values are distinct, so no x value is paired with more than one y-value and thus given relation is a function.

PLEASE HELP ASAP!!!!!! Quadrilateral PQRS, with vertex P(-5, -3), undergoes a transformation to form quadrilateral P′Q′R′S′, wit

Nana76 [90]

Answer:

The vertex Q' is at (4,5)

Step-by-step explanation:

Given:

Quadrilateral PQRS undergoes a transformation to form a quadrilateral P'Q'R'S' such that the vertex point P(-5,-3) is transformed to P'(5,3).

Vertex point Q(-4,-5)

To find vertex Q'.

Solution:

Form the given transformation occuring the statement in standard form can be given as:

$(x,y)\rightarrow (-x,-y)$

The above transformation signifies the point reflection in the origin.

For the point P, the statement is:

$P(-5,-3)\rightarrow P'(5,3)$

So, for point Q, the transformation would be:

$Q(-4,-5)\rightarrow Q'(-(-4),-(-5))$

Since two negatives multiply to give a positive, so, we have:

$Q(-4,-5)\rightarrow Q'(4,5)$

A rectangular pool is surrounded by a walk 3 meters wide. The pool is 4 meters longer than its width. If the total area of the p

motikmotik

x = 26 m is the width of the pool, length: 29+4 = 33 m.

Step-by-step explanation:

We have A rectangular pool is surrounded by a walk 3 meters wide. The pool is 4 meters longer than its width. If the total area of the pool walk is 372 square meters more than the area of the pool.

Let the width of the pool = x

Then the length will = (x+4) ,over all dimensions will be (x+6) by (x+6+4) or (x+10)

Total area - pool area = 372

$(x+10)*(x+6) - x(x+4) = 372\\x^{2}+16x+60-x^{2}-4x = 372\\12x+60 = 372\\12x = 372-60\\12x = 312\\x = 26$

∴ x = 26 ft is the width of the pool, length: 29+4 = 33 ft
