Answers

Answer 1

Answer:

234567

Step-by-step explanation:

Answer 2

Answer:

AP equation:

[tex]t_n=t_1+(n-1)d[/tex]

Based on the first two terms, we have:

[tex]t_1=3,\\t_2=9\\d=9-3=6[/tex]

The equation is:

[tex]t_n=3+(n-1)*6=3+6n-6=6n-3[/tex]

Next two terms are:

[tex]t_3=6*3-3=15\\t_4=6*4-3=21[/tex]

Kelly is attending physical therapyCB after knee surgery he walked 9 1/4 miles over 3 days how many miles is the per day simplilfy the answer as a mixed number

Answers

Answer:

The miles per day are: 3 1/12.

Step-by-step explanation:

With  the information provided, in order to find the miles per day you have to divide the number of miles he walked by 3 that is the number of days:

9 1/4÷3

In order to solve this, first you have to convert the mixed number to an improper fraction by multiplying the denominator for the whole number, add the numerator and this would be divided by the denominator:

(4*9)+1/4

36+1/4

37/4

Now, you divide this by 3:

37/4÷3

37/(4*3)

37/12

You can conver this fraction into a mixed number by dividing 37 by 12. 12 goes into 37 three times which would be the whole number. Then, three times 12 is 36 and the remainder is 1. So, 1 would be the numerator and the denominator stays th same which is 12. The mixed number is: 3 1/12.

According to this, the answer is that the miles per day are: 3 1/12.

Linda is 3 1/years younger than Rose. Joahn is 8 1/3years older than Linda. To the nearest year, what is the difference in Rose's age and Joahn's age?

Answers

Answer: 5 years

Step-by-step explanation:

Given

Linda is [tex]3\ \frac{1}{3}\ yr[/tex] younger than Rose

Johan is [tex]8\ \frac{1}{3}\ yr[/tex] older than Linda

Suppose the age of Rose is [tex]x[/tex]

So, Linda's age

[tex]x-\dfrac{3\times3+1}{3}=x-\dfrac{10}{3}[/tex]

Johan's age

[tex]x-\dfrac{10}{3}+\dfrac{8\times3+1}{3}=x+\dfrac{-10+25}{3}\\\\x+\dfrac{15}{3}=x+5[/tex]

Difference between the Rose's and Johan's age is

[tex]\Rightarrow x+5-x=5\ yr[/tex]

Given:

The compound inequality is:

[tex]3\leq 3x-4<2x+1[/tex]

To find:

The integer solutions for the given compound inequality.

Solution:

We have,

[tex]3\leq 3x-4<2x+1[/tex]

Case 1: [tex]3\leq 3x-4[/tex]

[tex]3+4\leq 3x[/tex]

[tex]\dfrac{7}{3}\leq x[/tex]

[tex]2.33...\leq x[/tex]             ...(i)

Case 2: [tex]3x-4<2x+1[/tex]

[tex]3x-2x<1+4[/tex]

[tex]x<5[/tex]                  ...(ii)

Using (i) and (ii), we get

[tex]2.33...<x<5[/tex]

The integer values which satisfy this inequality are only 3 and 4.

Therefore, the integer solutions to the given inequality are 3 and 4.

Why would the velocity of a river affect its ability to erode sediment?

Answers

The power of a river to cause erosion and carry sediment depends on several factors. A rivers slope, volume of flow, and the shape of its stream bed all affect how fast the river flows and how much sediment it can erode. ... When a river slows down, it drops its sediment load.

The velocity of the river that impact the capability for eroding the sediment should be explained below.

Impact on the velocity of a river:

In the case when the slope should be considered too gentle and here the velocity should be too slow for transporting the sediments that being supplied via weathering and erosion also the sediments should be piled up.

It rised  the gradient that resulted the water to flow quickly that increased the erosion and transport due to which it decreased the gradient.

Answer:

Step-by-step explanation:

1.)12.

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator.

Thus, the answer to 4 divided by 1/3 in fraction form is:

[tex]\frac{12}{1}[/tex]

To make the answer to 4 divided by 1/3 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

12

The answer is rounded to the nearest two decimal points if necessary.

[tex]\frac{12}{1}[/tex] is an improper fraction and should be written as 12.
