Answer:

Answer (C) ⇒ He replaced the wrong term with its reciprocal in step 2

Answer (A) ⇒ How many 3/8 's in 48

Step-by-step explanation:

∵ The distance = 25 miles

∵ The time = 2/3 hour

∵ Average speed = distance ÷ time

∴ Average speed = 25 ÷ 2/3 ⇒ step 1 (he is √)

= 25 × 3/2 ⇒ step 2 (his 1st error 1/25 × 2/3)

= 75/2 miles/h

∵ How many 3/8 's are in 48 means:

48 ÷ 3/8 = 48 × 8/3 = 128

∴ Answer (A) is best modeled with a division expression

Answer:

1. Leona traveled 25 miles in 2/3 of an hour. What was her average speed in miles per hour?

speed = distance/time

So, her speed will be 25/2/3

So, this becomes : 25*3/2

Nate did the wrong calculation here.

Instead of inversing 2/3 , he inversed 25.

So, answer is C-He replaced the wrong term with its reciprocal in step 2.

2. A is right.

How many 3/8 's are in 48?

B is multiplication, C is addition and D is subtraction.

What is the inverse function of y = x^2+ 4? Show all of your work for full credit.

Effectus [21]

Answer:

Look at the picture

Step-by-step explanation:

y = x^2 + 4 replace x and y

x = y^2 + 4 subtract 4 from both sides

x - 4 = y^2 sqaure root both sides

In bioligy class cher is viewing cells with a microscope. cell h measures 8.76x10^-3 microns in diameter and cell v measures 2.1

3241004551 [841]

Answer:

Larger cell 400 times bigger cell than the smaller cell

Step-by-step explanation:

Given:

diameter of the cell h = $8.76\times10^{-3}$

diameter of the cell v = $2.19 \times10^{-5}$

To Find:

How many tines larger is the bigger cell than the smaller cell?

Solution:

The cell h with diameter $8.76\times 10^{-3}$ is larger and the cell v with diameter $2.19 \times 10^{-5}$ is small. To find the number of times it is larger, we can divide the larger cell diameter by smaller cell diameter

=> $\frac{8.76\times 10^{-3}}{2.19 \times 10^{-5}}$

=> $\frac{8.76\times 10^ {-3} \times 10^{5}}{2.19 }$

=> $\frac{8.76\times 10^ {(-3+5)}}{2.19 }$

=> $\frac{8.76\times 10^2}{2.19 }$

=> $\frac{876}{2.19}$

=> 400

Larger cell is the bigger cell than the smaller cell by 400 times

The total amount of fiber (in grams) in a package containing x apples and y oranges is given by the equation 5x + 10y = 110. Is

Flauer [41]

The answer is NO
Because if x=5 the equation is 125+10y=110
In this case y will be a negative
You can’t have a negative oranges
So the answer is NO
