The vagabonds were 200 miles apart at 2 p.M and were headed toward each other if they met at 6 p.M and one was traveling 10 mile

muminat

Answer:

<em>The answer is 200</em>

Step-by-step explanation:

<em>To solve the question given, let us recall the following,</em>

<em>Let r4=200 miles apart</em>

<em>r=50 mph combined speed </em>

<em>Where </em>

<em>2f+10=50 </em>

<em>2f=40 </em>

<em>f=20 </em>

<em>f+10=30 </em>

<em>or we can express it in another way,</em>

<em>which is</em>

<em>f x4+(f+10)x 4=200 </em>

<em>f x4+f x4+40=200 </em>

<em>8f+40=200</em>

<em>Then</em>

<em>8f is =160 </em>

<em>f=20 </em>

<em>f+10=30 </em>

<em>Therefore,</em>

<em>4x 20+4 x 30=200 </em>

<em>80+120=200 </em>

<em>200=200</em>

I need help trying to figure this out I think I have and answer but I want to make sure.

yKpoI14uk [10]

Answer:

34

Step-by-step explanation:

The mean is calculated as

mean = $\frac{frequency(midpoint)}{frequency}$

let x be the missing frequency, then

Total frequency × midpoint

= (16 × 2) + 7x + (20 × 12) + (10 × 17) = 32 + 7x + 240 + 170 = 442 + 7x

Total frequency = 16 + x + 20 + 10 = 46 + x, thus

$\frac{242+7x}{46+x}$ = 8.5 ( cross- multiply )

442 + 7x = 8.5(46 + x)

442 + 7x = 391 + 8.5x ( subtract 8.5x from both sides )

442 - 1.5x = 391 ( subtract 442 from both sides )

- 1.5x = - 51 ( divide both sides by - 1.5 )

x = 34

The missing frequency is 34

During the school year or each student planted 2 * 10^2 trees as part of a community service project. If there are 3.5 * 10^3 st

Nookie1986 [14]

Total 7*10^5 trees were planted.

Further explanation:

The product of both quantities will give us the total number of trees planted by the students for the community project.

So,

Given

$Trees\ planted\ by\ each\ student=2*10^2\\Total\ students\ in\ school=3.5*10^3\\Total\ trees\ planted= (2*10^2)*(3.5*10^3)\\= 7*10^5\ trees$

So, total 7*10^5 trees were planted.

uranmaximum [27]

Answer:

$2,400

Step-by-step explanation:

Ken intends to start a savings account

10% = leisure spending

This means 90% = Expenses for school

Let us represent the amount he must save as : x

Hence in other for him to have $2,160 in his savings account, the amount Ken must earn is calculated as:

90/100 × x = $2,160

Cross Multiply

90x = $2,160 × 100

x = ($2,160 × 100) ÷ 90

x =$2,400

Therefore, the amount Ken has to earn to have the amount needed for school is $2,400
