1 answer:

6 0

1) 125mph
miles per minute
= 125/60
= 25/12
= 2.083 miles per minute

2) 10mph
miles per second
= 10/60/60
= 1/360 feet per second

3) 2 megabytes per second
= 2*60*60
= 7200 megabytes per hour

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth

mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

$Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3$

Evaluate the products

$Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8$

Evaluate the sum

$Total = \frac{4+4+9+4+15}8$

Evaluate the numerator

$Total = \frac{36}8$

Evaluate the quotient

$Total = 4\frac{1}2$

Hence, the total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches

6(4+7k)=-3k-6(4+k) k=?

Alona [7]

Answer:

-16/15

Step-by-step explanation:

ok let's break this down.

6(4+7k) = 6*4 + 42k (use distributive property)

3k - 6(4+k) = 3k - 24 - 6k (do the same thing)

24 + 42k = 3k - 24 -6k (let's simplify this a bit)

24+42k = -24-3k (add 3k on both sides)

24+45k=-24 (subtract 24 on both sides)

45k = -48

k = -48/45 or -16/15

Solve this system of equations by substitution<br> x=y+3<br> x+7=2y

stiv31 [10]

Answer:

(13, 10 )

Step-by-step explanation:

Given the 2 equations

x = y + 3 → (1)

x + 7 = 2y → (2)

Substitute x = y + 3 into (2)

y + 3 + 7 = 2y

y + 10 = 2y ( subtract y from both sides )

10 = y

Substitute y = 10 into (1) for corresponding value of x

x = 10 + 3 = 13

solution is (13, 10 )
