Marisol went to a hair salon for a haircut. The hair stylist cut off 3 inches of her hair. The length of her hair is now 11 inches. Let b represent the length of her hair before she went to the salon. Which of the following represents an equality between two different ways of expressing the length of Marisol's hair now?
A.b-3=11 B.b=11 C.b+3=11 D. 11b=3

Answer:

The first one (highlighted one)

Step-by-step explanation:

The answer is the one selected. When multiplying and subtracting numbers, you do the combination that is multiplying before you subtract-unless there are numbers in parenthese. You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example  the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.

Answer:

r = 3 in.

Step-by-step explanation:

vol = Bh   where B is the area of the base and h is the height of the cylinder

The base is a circle so

B = [tex]\pi r^{2}[/tex]    h = 5

141.3 = 3.14(5)[tex]r^{2}[/tex]

        = 15.7[tex]r^{2}[/tex]

[tex]r^{2}[/tex] = 141.3/15.7 = 9

r = 3 in.

Answer:

12

Step-by-step explanation:

Answer:

x = 14

Step-by-step explanation:

two negatives become a positive so the equation is now

x + 3 = 17

subtract 3 from both sides, giving you 14

Answer:

[tex]N_t=6.455\ yards[/tex]

Step-by-step explanation:

From the question we are told that:

Total String [tex]N=71/2[/tex]

Strip size [tex]N_s=11/2[/tex]

Generally the equation for Total Number of strip cut [tex]N_t[/tex] is mathematically given by

[tex]N_t=\frac{N}{N_s}[/tex]

Therefore the  strips of string can she cut with 7 1/2 yards is Given as

[tex]N_t=\frac{71/2}{11/2}[/tex]

[tex]N_t=\frac{71}{2}*\frac{2}{11}[/tex]

[tex]N_t=\frac{71}{11}[/tex]

[tex]N_t=6.455\ yards[/tex]

Answer:

3 hours and 50 minutes

Step-by-step explanation:

Given that

Sarah drives for 1 hours and 40 minutes

And, rest for 25 minutes

And, then drive for another 1 hour & 45 minutes

We need to find out the total travel time in hours and minutes

First we convert into minutes i.e.

= 1 hour + 40 minutes + 25 minutes + 1 hours + 45 minutes

= 60 minutes + 40 minutes + 25 minutes + 60 minutes + 45 minutes

= 230 minutes

i.e.

3 hours and 50 minutes

Answer:

Step-by-step explanation:

6 , -4

Reason:

If you add 6 and (-4) , you will get  2   & if you multiply 6 and -4, you will get -24

Answer:

$113.20

Step-by-step explanation:

Simple interest for the fourth year = 13.20 ( 3.30 - 4)

New amount in the bank acount for 4th year = 100+ (3.30 x4) = 113.20

Answer:

120

Step-by-step explanation:

The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,

[tex]\implies ^n P_r = \dfrac{n! }{(n-r)!} [/tex]

⇒ 5! / (5-5)!

⇒ 5! / 1!

⇒ 5!

⇒ 5 × 4 × 3 × 2 × 1

⇒ 120

Answer:

False

Kilometer

Step-by-step explanation:

First Question:

1 km = 1000 m

2 km = 2 * 1 km = 2 * 1000 m = 2000 m

Centennial Park is 2 km = 2,000 m away.

Canatara Park is 2,548 meters away.

Since 2,548 > 2,000, Canatara Park is farther away than Centennial Park.

Answer: False

Answer:

y = a 2 d x + k y=a2^{dx}+k y=a2dx+k

Step-by-step explanation:

Determine the exponential function in the form y = a 2 d x + k y=a2^{dx}+k y=a2dx+k of the given graph. To solve this problem, we're going to need to find the variables "a", "d", and "k". Remember, we can find "k" from the graph, as it is the horizontal asymptote.

Answer:

y = (2/3)x + 3

Step-by-step explanation:

Notice that if we start at any x value shown in the table and increase x by 3, y will increase by 2.  Thus, the slope of the line is 2/3.  

From the entry (0, 3), we know that the y-intercept is b = 3.

Thus, y = mx + b becomes:

y = (2/3)x + 3

The answer is x = 4

Step 1: Simplify both sides of the equation.

3 /2 (x−6)=−3

( 3 /2 )(x)+( 3 /2 )(−6)=−3(Distribute)

3 /2 x+−9=−3

3 /2 x−9=−3

Step 2: Add 9 to both sides.

3 /2 x−9+9=−3+9

3 /2 x=6

Step 3: Multiply both sides by 2/3.

( 2 /3 )*( 3 /2 x)=( 2 /3 )*(6)

x=4

Answer:

x=4

Answer:

5 cm

Step-by-step explanation:

Arc length (S) = 10 cm

Central angle [tex] (\theta) [/tex] = 2 radians

We need to find: radius of the circle (r)

[tex] \because S = r \theta [/tex]

[tex] \therefore 10 = r(2) [/tex]

[tex] \therefore r= \frac{10}{2} [/tex]

[tex] \therefore r= 5\: cm [/tex]
