Answer:

B is true

Step-by-step explanation:

A. 4^5*4^5 = 4^(5+5) = 4^10 ≠ 4^15

FALSE

B. (5^4)^5 = 5^(4*5) = 5^20

TRUE

C. 3^1*3^0 = 3^(1+0) = 3^1 ≠ 3^0

FALSE

D. 6^20/6^10 = 6^(20 - 10) = 6^10 ≠ 6^2

FALSE

A hose is filling a water tank at the rate of 70 gallons per minute. A loose drain plug causes 8 gallons per minute to drain out

Alinara [238K]

62x=y
1860/62=30min

70 gallIons per minute, minus the 8 gallons per minute would give you a growth of 62 gallons per minute. you need 1860 gallons in total so divid that by your growth in which it'll take 30 minutes to fill up a 1860 gallon tank.

A helicopter hovers 1450 feet above a small island. The figure shows that the angle of depression from the helicopter to point P

puteri [66]

Answer:

1668 feet.

Step-by-step explanation:

We know the opposite side of the right triangle and we need the adjacent side, so we use the tangent function.

If the distance required is x (adj side) we have:

tan 41 = opp/adj

tan 41 = 1450/x

x = 1450 / tan 41

= 1668.03

A triangle has a perimeter of 72 units, and two of its sides measure x units and 3x units, respectively. Which inequality repres

blagie [28]

Answer:

$x$

Step-by-step explanation:

Given: Perimeter of triangle= 72 units

Measure of one of the side= x units

Measure of second side = 3x units

We know the perimeter of triangle is equal to sum of all sides.

Now, finding the possible value of x

forming an inequality to determine the value of x

Remember triangle has three sides, however, measure of only two sides are given.

⇒ $x+3x < 72\ units$

⇒ $4x$

Dividing both side by 4

⇒ $x < 18$

∴ The inequality to represents all possible values of x is $x < 18$

How many shapes are in the world

Montano1993 [528]

There are an infinite number of shapes, because a shape can have any number of sides. This is where we get into our laws of fractals. A fractal is a shape with an infinite perimeter and area, meaning that every level of infinity is another shape, but can be beat by another shape. However, this is all philosophical math and goes way beyond the context of your question.

To keep it short and simple, there are an infinite number of shapes in the world.

Figure B is a scaled copy of Figure A. <br> What is the scale factor from Figure A to Figure B?

Free_Kalibri [48]

The scale factor to convert Figure A to B is $\frac{1}{2}$ (0.5)

Step-by-step explanation:

Step 1; To determine the scale factor, we need to know the dimensions of the shape before scaling and its dimensions after scaling. From the given diagram, figure A has a base length of 6 units while its height is 4 units. Figure B has a base length of 3 units and a height of 2 units.

Step 2; To find the scale factor, we divide a particular dimension from figure B with the same dimension in figure A.

The base length of figure B /the base length of figure A = $\frac{3}{6}$ = $\frac{1}{2}$ ,

Similarly, the height of figure B / the height of figure A = $\frac{2}{4}$ = $\frac{1}{2}$ .

So by multiplying figure A with scale factor $\frac{1}{2}$ we get figure B.
