Answer:

b

Step-by-step explanation:

Answer:

Option D.

Step-by-step explanation:

The given equation is

[tex]10b=5(\sqrt{c}+2)[/tex]

We need to find an equation which is equivalent to the given equation.

Using distributive property, we get

[tex]10b=5(\sqrt{c})+5(2)[/tex]

[tex]10b=5\sqrt{c}+10[/tex]

Subtract both sides by 10.

[tex]10b-10=5\sqrt{c}[/tex]

Divide both sides by 5.

[tex]\dfrac{10b-10}{5}=\sqrt{c}[/tex]

Taking square on both sides.

[tex]\left(\dfrac{10b-10}{5}\right)=(\sqrt{c})^2[/tex]

[tex]\dfrac{(10b-10)^2}{25}=c[/tex]

[tex]c=\dfrac{(10b-10)^2}{25}[/tex]

This equation is equivalent to the given equation.

Therefore, the correct option is D.

Answer: 3 notebooks

Step-by-step explanation:

First take the three mechanical pencils out of the equation by doing

15 - (3*1.75) = 9.75.  Because each notebook costs 3 dollars, she can afford 3 notebooks, with 1 dollar left over.

Hope it helps <3

Answer:

3 notebooks

Step-by-step explanation:

(1,75x3)=5.25   15.00-5.25=9.75

2.99x=9.75

x=3,26

so she can buy 3 notebooks

Answer:

Step-by-step explanation:

d= distance

t= time

The independent variable is t, time. The distance the car travels depends on the time in hours spent travelling. The dependent variable is d, distance. Here is a table with 5 coordinate pairs that can be used.

(T)        (D)

1           30

2          60

3          90

4         120

5         150

These are the coordinate pairs for the function. When we use division and determine the rate of change, we can determine that the average rate of speed (MPH) is 30 MPH.

Answer:

The length of the hall way

the weight of the wombat

Answer:

yes

Step-by-step explanation:

Answer:

x = 0   ,   x = -2

Step-by-step explanation:

The function given to us is:

f(x) = 3/2x - 5

g(x) = x² + 2x

We have to find the input x, for which the output of the function g(x) becomes 0.

It means that there is no use for the function f(x) in this question, so discard it

Substitute g(x) = 0 into the given equation of g(x):

g(x) = x² + 2x

0 = x² + 2x

Take x common from both the terms:

x(x+2) = 0

Thus, the values of x can be written as:

x = 0     ,     x + 2 = 0

x = 0     ,     x = -2

Answer:

A.64/50

Step-by-step explanation:

8/10*8/5

64/50

The least simplified form of the equation is 32/25

The simplified form of expression is option (D) 64/50 is the correct answer.

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. It involves, multiply out the brackets and then simplify the resulting expression by collecting the like terms.

For the given situation,

The expression is (8/10)(8/5)

The simplified form of expression is

⇒ [tex](\frac{8}{10} )(\frac{8}{5} )[/tex]

⇒ [tex]\frac{64}{50}[/tex]

Hence we can conclude that the simplified form of expression is option (D) 64/50 is the correct answer.

Answer:

B. (2, 0)

Step-by-step explanation:

Step 1: Elimination (Subtract the 2 equations/add the 2 equations, one being negative)

b = 0

Step 2: Plug in b to get a

6a - 5(0) = 12

6a - 0 = 12

6a = 12

a = 2

Answer:

This equation is false

Step-by-step explanation:

Well,

-11b + 7 = 4 - 11b + 7 = 40

combine like terms

-11b + 7 = -11b + 3 = 40

Communicative property

-3 to both sides

-11b + 4 = -11b = 40

-4 to both sides

-11b = -11b = 36

+11b to both sides

0 = 36

0 is not equal to 36 meaning that this equation is false.

Thus,

the equation given is false.

Answer:

a) What is her average speed in mph?

= 65 mph

b) How many miles does Matthew drive?

=310 miles

Step-by-step explanation:

The average speed in meters per hour (mph) of Helen is 65 miles per hour

Given:

Total distance = 195 miles

Time taken = 3 hours

= 195 miles ÷ 3 hours

= 65 miles per hour

If Matthew drives at an average speed of 62 mph for 5 hours.

Total distance between traveled = Average speed × Time taken

= 62 mph × 5 hours

= 310 Miles

Therefore the total miles Helen traveled in 5 hours at the rate of 62 mph is 310 miles

This is an extremely easy question. Your correct answer is 1/7,200 or 0.01389%

Step-by-step explanation:

Since you have to choose the three numbers and one super ball to be able to win the lottery, your chances of getting 3 white numbers is 1/10 x 1/9 x 1/8 = 1/720

The chances of getting the super ball is 1/10

And the chances of winning the jackpot is 1/720 x 1/10 = 1/7,200 = 0.01389%

Answer:

Part A: 7/10

Part B: 1/2

Part C: look below*

Step-by-step explanation:

Part A:

The probablity is a 7/10 because in the previous record the gerbil went left 7 out of the 10 times

Part B:

Theoretically the gerbil has a 1/2 of going either left or right since there are two options.

Part C:

The experimental probabilty does not equal the theoretical probability because during the trial the gerbil went left 7/10 and theoretically the gerbil would go left 5/10 times.

Answer:

Option A. √(x + 1)

Step-by-step explanation:

Data obtained from the question include:

f(x) = √(x² – 1)

g(x) = √(x – 1)

(f/g) (x) =..?

(x² – 1) => difference of two square

(x² – 1) => (x – 1)(x + 1)

f(x) = √(x² – 1)

f(x) = √(x – 1)(x + 1)

(f/g) (x) = f(x) /g(x)

f(x) = √(x – 1)(x + 1)

g(x) = √(x – 1)

(f/g) (x) = √(x – 1)(x + 1) / √(x – 1)

(f/g) (x) = √[(x – 1)(x + 1) / (x – 1)]

(f/g) (x) = √(x + 1)

Step-by-step explanation:

Let the length of the perpendicular dropped from the right angle to the hypotenuse be h units.

Answer:

1500

Step-by-step explanation:

Use the right triangle altitude theorem.

x/900 = 2500/x

x^2 = 900 * 2500

x = sqrt(900 * 2500)

x = 30 * 50

x = 1500

Now,

[tex]t = \frac{i \times 100}{p \: \times \: r} [/tex]

[tex] = \frac{28800 \times 100}{30000 \times 12} [/tex]
