Sara can type 90 words in 4 minutes. About how many words would you expect her to type in 10 minutes at this rate?

Talja [164]

Answer:

She can type 225 words in 10 minutes

Step-by-step explanation:

We can find the rate by dividing the number of words by the time

90 words/ 4 minutes

22.5 words per minute

Now to find the number of words in 10 minutes, multiply the rate times the time

22.5 * 10 = 225

She can type 225 words in 10 minutes

2. The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers aj set up the variables (2

storchak [24]

Answer:

Larger number = 34

Smaller number = 17

Step-by-step explanation:

Given that:

Sum of numbers = 51

Let,

x be the larger number

y be the smaller number

According to given statement;

x+y=51 Eqn 1

x = 2y Eqn 2

Putting x=2y in Eqn 1

2y+y=51

3y=51

Dividing both sides by 3

$\frac{3y}{3}=\frac{51}{3}\\y=17$

Putting y=17 in Eqn 2

x=2(17)

x=34

Hence,

Larger number = 34

Smaller number = 17

Point m is the midpoint of ab¯¯¯¯¯ . am=2x+9, and ab=8x−50. what is the length of am¯¯¯¯¯¯ ?

iogann1982 [59]

Since m is the midpoint of ab, then the following relationship is fulfilled:
$am = \frac{ab}{2}$
Therefore, substituting values we have:
$2x+9 = \frac{8x-50}{2}$
From here, we clear the value of x.
We have then:
$2x+9 = 4x-25$
$9+25 = 4x-2x$
$34 = 2x$
$x = \frac{34}{2}$
$x = 17$
Then, the value of am, is given by substituting x in the expression:
$am=2x+9$
Substituting we have:
$am=2(17)+9$
$am=34+9$
$am=43$
Answer:
the length of am is:
$am=43$
