Simplify the expression -3 ÷ (-2/5

Harlamova29_29 [7]

Answer:

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

Parenthesis

Exponents

Multiplication>Division (Depends on which comes first from left to right)

Addition>Subtraction (See Multiplication>Division)

So First, lets solve the Parenthesis. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just Divide.

-3/-.4=7.5

The solution is 7.5

Mr. Vu can drive his new electric car 194 miles before he needs to charge his battery. How far can Mr. Vu’s car go on 15 battery

const2013 [10]

Answer:

Mr. Vu can go 2910 miles on 15 battery charges (D).

Step-by-step explanation:

If 1 battery charge lasts 194, then we can multiply 15 by 194 to find this amount of miles.

15 times 194 equals 2910, so with 15 battery charges, he would go 2910 miles.

An urn contains six red balls and four green balls. A sample of seven balls is selected at random.

KIM [24]

There are 10 balls in the Urn Total.

Red: 6

Green: 4

Question One: The probability that five red and two green is selected is likely. (as that is over half for both)

Question Two: Impossible. There is only 6 red balls, and 7 are taken from the urn. Thus it would at most be possible for 6 red and 1 green.

Question Three: At least four is likely, as there is more red then green in the Urn.

Hope I helped!

Write an exponential function for the graph that passes through the points (0,4) and (2, 36). Use the formula y=ab^x

fomenos

Answer:

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3 Solve each equation for a.

2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3

Cross multiply: 2b3 = 4b2 Divide both sides by b2

2b = 4 a = 2/4 = 1/2

b = 2

y = 1 (2)x
