Calculate area of the triangle:
Height x Lenght of base x 1/2
4cm x 6cm x 1/2 = 12 square cm

Now multiply the are with the length of the prism:

12 square cm x 10 cm = 120 cubic cm

Carla and Frank can each wash a car and clean the interior in 2 hours, but Missy needs 3 hours to do the work. If the three work
irina1246 [14]

Remark

Start by figuring this out for 1 car. Worry about the 7 part when you find 1.

This problem is used quite frequently in physics. For example resistors in parallel use the same equation.

Formula

1/frank + 1/carla + 1/missy = 1/ time taken to do 1 mar.

Givens

Frank = 2 hours

Carla = 2 hours

Missy = 3 hours.

Substitute and Solve

1/2 + 1/2 + 1/3 = 1/Three_together.

3/6 + 3/6 + 2/6 = 1/Three_together.

8/6 = 1/Three_together. Cross multiply

8 * Three_Together = 6*1

8 * Three_Together = 6 Divide by 8

Three_Together = 6/8 = 3/4 = 0.75 hours. or 45 minutes for 1 car

Seven Cars

For 7 cars multiply 0.75 by 7

7 * 0.75 = 5.25 hours. <<<< Answer

If the blue radius below is perpendicular to the green chord and the segment
IgorLugansk [536]

Answer:

O B. 17 units

Step-by-step explanation:

The chord is AC and the radius of the circle is perpendicular to the chord at B. AB = 8.5 units. According to the perpendicular bisector theorem, if the radius of a circle is perpendicular to a chord then the radius bisects the chord. This means that chord AC is bisected by the radius of the circle at point B. The length of the circle is calculated using:

AB=\frac{AC}{2}\\ AC=2*AB\\cross multiplying:\\AC = 2*8.5\ units\\AC = 17 \ units

The length of the chord is 17 units.

Write a difference quotient that best approximates the instantaneous rate of change of g at x=0
Rina8888 [55]

Step-by-step explanation:

The difference quotient is simply the slope of the line connecting two points on a curve.  For the best approximation, we should use points that are closest to x = 0.  In this case, the points are (-0.001, 1.999) and (0.001, 2.001).

m = (2.001 − 1.999) / (0.001 − (-0.001))

m = 1

String a is 35 centimeters long. String b is five times as long as string a. Both are necessary to create a decorative bottle. F
gayaneshka [121]

Answer:

35.7 m.

Step-by-step explanation:

To find the length of string b, you have to multiply 35 by 5. You get 175, and so when it asks how much total string you need for each bottle you must add 175 and 35, which gets you 210. Then, to find how much you need in total for 17 bottles  you need to multiply 210 by 17. This gets you 3570 cm, which you can convert to 35.7m.
