Verizon [17]

Answer:

you both will reach the home at the same time.

I) You can catch your sister.

ii) Reason: you both will reach home at the same time.

Step-by-step explanation:

Let "d" be distance from school to home.

Let's find the speed of you and your sister.

Speed = $\frac{Distance}{Time}$

Your speed = $\frac{d}{20}$

Your sister's speed = $\frac{d}{35}$

Today, You stayed for some extra help by the time your sister covered $\frac{3}{7}$ of the way home.

Remaining distance to reach the home = $1 - \frac{3}{7}d = \frac{7-3}{7}d = \frac{4}{7}d$

=

Now let's find the time to be taken your sister to reach the home.

Time = $\frac{distance}{speed}$

= $\frac{\frac{4}{7}d }{\frac{1}{35} d} = \frac{4}{7} *\frac{35}{1} = 20$

So, your sister will take 20 minutes to get home by the time your start.

We know that it takes you 20 minutes to reach your home.

Therefore, you both will reach the home at the same time.

I) You can catch your sister.

ii) Reason: you both will reach home at the same time.

Three hikers are dividing the costs of a hiking trip evenly. They bought two permits that cost $15 each, three tram tickets that

cestrela7 [59]

Each hiker owes $41 or 4100 cents for the hiking trip.

<u><em>Explanation</em></u>

Cost of each permit is $15. So, the cost of <u>two permits</u> will be: $(\$15*2)= \$30$

Cost of each tram ticket is $19. So, the cost of <u>three tickets</u> will be: $(\$19*3)=\$ 57$

Cost of <u>one can</u> of bear spray is $36.

So, the total cost of the hiking trip $=\$30+\$57+\$36=\$123$

As the <u>three hikers</u> are dividing the total costs of the trip <u>evenly</u>, so each hiker owes $=\frac{\$123}{3}=\$41$ or 4100 cents.

Hi Jessica,
<span>Remember PEMDAS (Parenthesis, Exponents, Multiplication & Division, Addition & Subtraction).

√3 x 66.15/4.41 {Exponents/Cube & Square Roots First}

1.73 x 66.15 ÷ 4.41 {Multiplication}

114.4395 ÷ 4.41 {Division}

25.95 {Final Answer}

One number was divided by 2, followed by this quotient being multiplied by 4. next, the product was added to 9. the total sum wa

grin007 [14]

Answer:

Step-by-step explanation:

First, turn the word problem into an equation:

n(a number) was divided by 2

$\frac{n}{2}$

followed by this quotient beying multiplied by 4

$\frac{n}{2}$ *4

the product was added to 9

$\frac{n}{2}$ *4+9

the total sum was 25

$\frac{n}{2}$ *4+9 = 25

use PEMDAS to solve the equation

subtract 9 on both sides

$\frac{n}{2}$ *4 = 16

cancel the 2 and the 4 using factorization

n*2 = 16

divide 2 on both sides

n = 8
