Figure A has a radius of 2 inches. It is dilated by a scale factor of 4 to form figure B. What is the radius of figure B?

1 answer:

7 0

Given that figure A with radius of 2 inches is dilated to form figure B, the radius of B will be given by:
Radius B=(radius A)×(scale factor)
but
scale factor=4
thus
Radius of B will be:
2×4
=8 inches

Answer:

8.84×10 To the power of -1

Step-by-step explanation:

stated number and decimal number is 8.84

goal: find the standard form of that number.

Defenition: (Plagarism Copyrights) The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write × 10(to the power of a number).

So 0.884 is 8.84/10

next put the numerator of 10 to 1 - 1/10

mulitiply 8.84 by 1/10-

this, the answer is multiply 8.84 by 10 to the power of -1

which is basically 8.84×10 To the power of -1

Someone solve this equation much appreciated!

daser333 [38]

Answer:

$\frac{2A}{h} = b$

Step-by-step explanation:

this can be done by simple manipulation .
in the given equation, A is the subject.
so, by the above statement you can understand the meaning of making something as a subject.

given equation: A = 1/2 bh

multiply both the sides by 2,

2A = bh

divide both the sides by h,

$\frac{2A}{h} = b$

so, the required form is : $\frac{2A}{h} = b$

A 3-gallon tub of ice cream yields about 90 scoops of ice cream. There are roughly 3785 cubic centimeters in 1 gallon. Determine

ASHA 777 [7]

Answer:

The radius of the scoop is r = 3.1 cm

Step-by-step explanation:

Since 3 gallons yields 90 scoops, and 1 gallon = 3785 cm³.

3 gallons = 3 × 3785 cm³ = 11355 cm³

So we have 11355 cm³ in 3 gallons which is also the volume of 90 scoops.

Since 90 scoops = 11355 cm³, then

1 scoop = 11355 cm³/90 = 126.2 cm³

Now, if each scoop is a sphere, the volume is given by V = 4πr³/3 where r is the radius of the scoop. Since we need to find the radius of the scoop, r, making r subject of the formula, we have

r = ∛(3V/4π)

Substituting V = 126.2 cm³, we have

r = ∛(3× 126.2 cm³/4π)

= ∛(378.6 cm³/12.57)

= ∛30.13 cm³

= 3.1 cm

So, the radius of the scoop is r = 3.1 cm
