<h3>Answer:  434,500</h3>

You may need to erase the comma

To get this answer, move the decimal point to the right 5 spaces to go from 4.345 to 434,500

If the exponent was -5, then you would move five spaces to the left.

Does anyone know what b is?
sveticcg [70]

Answer: b = 17

Step-by-step explanation: The figure shows a triangle which upon closer observation is actually two triangles placed one inside the other. We have triangle QTR (the larger one) and triangle PTS (the smaller one).

The line PS is parallel to line QR, so in effect what we have here are two similar triangles. The ratios of similarity can be derived as

Line QT/line TR = line PT/line TS OR

Line QT/line QR = line PT/line PS.

With these ratios in mind we can now write the following expressions from the similar triangles;

QT = 2b + (2b - 17) and

TR = 16 + 8

TR = 24

Hence,

2b/16 = 2b + (2b - 17)/24

(That is, PT/TS = QT/TR)

2b/16 = (4b - 17)/24

By cross multiplication we now have,

2b(24) = 16(4b - 17)

By expanding the brackets we now have

48b = 64b - 272

By collecting like terms, 64b now moves to the left side of the equation and becomes negative

48b - 64b = -272

-16b = -272

Divide both sides of the equation by -16

b = 17

**Note** A negative number divided by another negative number yields a positive answer.

Carson needs 3 quarts of water to make fruit punch, but has only a l-cup measuring cup.
olga_2 [115]

Answer:

Cups of water she needs to make the punch is 12.

Step-by-step explanation:

Amount of water Carson need to make fruit punch = 3 quarts

2 cups is 1 pint

2  pints is 1 quart

1 pint = 1/2 quarts

2 cups is 1 pint which is 1/2 quarts

So, 1 cup:

1 cup is 1/2 times 2 quarts

1 quart is 1 times 2 times 2 cups equals 4 cups

So, 3 quarts equals 3 times 4 cups which equals 12 cups.

So it is 12 cups.

this coordinate plane shows the floor plan of a gym in Sunnyvale High School what is the location at -2.5,3.0​
muminat

Answer:

The answer is D. water fountain.

Step-by-step explanation:

If you look at the graph for the point (-2.5, 3.0), you need to find -2.5 on the x-axis and 3 on the y-axis. The "Water Fountain" point is past negative two but not quite at 3 yet; it's in between. Then you go up three times. Even though the graph is going by 2's, the point is located exactly in between 2 and 4, which is 3. Hope this helps!
