Jillian has three different bracelets (x y and z) to give to her friends as gifts In any order she prefers if the bracelet y is

9966 [12]

Answer:

Number of ways to chose bracelet = 2 ways

Step-by-step explanation:

Given:

Total number of bracelet = 3

Y is chosen first

Find:

Number of ways to chose bracelet

Computation:

Y is chosen first so remain number of bracelet is 2

So,

Number of ways to chose bracelet = !2

Number of ways to chose bracelet = 2 × 1

Number of ways to chose bracelet = 2 ways

An animal shelter uses 41 cups of food each day to feed the dogs and cats. Each dog eats 2 cups per day. The cats eat a total of

nignag [31]

Answer:

The equation that can be used to find d is $2d+17=41$

$d=12\ dogs$

Step-by-step explanation:

Let

d -----> the number of dogs

we know that

The linear equation that represent this situation is

$2d+17=41$

Solve for d

Subtract 17 both sides

$2d=41-17$

$2d=24$

Divide by 2 both sides

$d=12\ dogs$

<h3>How to find compound interest?</h3>

Question(1)

Using compound interest formula,

$A = p(1 + \frac{r}{n} )^{nt}$

where

p = principal
r = rate
n = number of times
t = time

Therefore,

p = 30,000

r = 3.5% = 0.035

t = 10

n = 1

Therefore,

$A = 30000(1+\frac{0.035}{1} )^{1X10}$

A = $42,317.96

Question 2:

Pamela takes 12 hours to complete a task.

Kelvin takes 20 hours to complete same task.

The time it will take both of them can be computed as follows:

using rate principle,

let

x = time it will take both of them to do the work together.

$\frac{1}{x}=\frac{1}{12} + \frac{1}{20}$

$\frac{1}{x}=\frac{20+12}{240}$

$\frac{1}{x}=\frac{32}{240}$

cross multiply

240 = 32x

x = 240 / 32

x = 7.5 hours

Therefore, it will take Pamela and Kevin 7.5 hours to complete the task together

Solve, graph, and express x + 5x – 6 < 12 in interval notation.

Nikolay [14]

Answer:

Solve: x < 3 Graph: *attached* Interval Notation: (-∞,3)

Step-by-step explanation:

Solve:

combine like terms

$x + 5x -6 < 12$

$6x -6 < 12$

Add 6 on either side of the inequality

$6x < 18$

Divide by 6 on either side of the inequality

$x < 3$

Graph:
