The speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

Let the speed of the Elvira be x. Then the speed of the Altheia will be (x - 6).

Let the distance between the coffee shop and Elvira's house be d.

Then the distance between the coffee shop and Altheia's house will be (3.6 - d).

Then we have

x = d / 0.5 ...1

(x - 6) = (3.6 - d) / 0.6 ...2

In solving the equations 1 and 2, we have

x = 6.545 and d = 3.2725 miles

Then the speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.

More about the speed link is given below.

Jeanne makes hair bows to sell at the craft fair. Each bow requires 1.5 yards of ribbon.
UkoKoshka [18]

Answer:

a) 378 foot

b) 3780¢

c)10^3\times 2^1\times 3^3\times 7^1

Step-by-step explanation:

Given: Ribbon required to make 1 bow = 1.5 yards

We know that 1 yard = 3 foot

a) Number of bows Jeanne wants to make = 84

Foot of ribbon required to make 84 bows

= Number of bows Jeanne wants to make × Ribbon required to male 1 bow

= 84 × 1.5 yards

= 126 × 3 foot = 378 foot

Thus, Jeanne requires 378 foot of ribbon to make 84 bows.

b) Cost of ribbon = 10¢ per foot

Total money required to buy ribbon

= Cost of ribbon × Amount of ribbon required in foot

= 10 × 378

= 3780.00¢

c) Number of bows manufacture wants to make = 84 × 1000

= 84,000 bows

Amount of ribbon required to make bows

= 1000 × Amount of ribbon required to make 84 bows

=  1,000 × 378 = 378000 foot

To write it in exponential form:

378000 = 10^3\times 2^1\times 3^3\times 7^1

What is 400 in expanded form (Warfare you get brainliest)
MAXImum [283]
Hey there, Lets solve your question together 

Question - <span>What is 400 in Expanded form ? 
</span>
We know that expanded form is a spread out way to write a number by showing the value of each individual digit that contributes<span> to make the full number. 
</span>
Lets use an example to show expanded form

Number - 4,265 

= 4 x 1,000 + 2 x 100 + 6 x 10 + 5 x 1 

Now lets solve for the number 400 in expanded form. 

The number "4" is in the hundreds place 

The number "0" is in the tenths<span> place 
</span>
<span>The number "0" is in the One's place 

</span>Therefore 400 in expanded form is 400+00+0. 
 
<span>          Hope this helps </span>

WILL GIVE BRAINLIEST Mr. and Mrs. Bailey hope to send their son to college in eleven years. How much money should they invest no
Ronch [10]

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.

<h3>Compound interest</h3>

Compound interest is given by:

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

where A is the amount after t years, P is initial amount, r is the rate and n is the times compounded per period

Given that n = 1, r = 9% = 0.09, A = $7500 t = 11. Hence:

7500=P(1+\frac{0.09}{1} )^{1*11}\\\\P=\$2906.50

Mr. and Mrs. Bailey need to invest $2906.50 so as to send their son to college.
