Step-by-step explanation:

Step 1: Subtract the first part

$1\frac{1}{2} - \frac{1}{4}$

$\frac{3}{2} - \frac{1}{4}$

$\frac{6}{4}-\frac{1}{4}$

$\frac{5}{4}$

Step 2: Multiply both to get how much the brother drank

$\frac{5}{4} * \frac{2}{5}$

$\frac{2}{4}$

$\frac{1}{2} \ L$

This is a absolute value equation solve for x 5 4x + 2) + 10 = 25

Alina [70]

Answer:

x = 1/4

Step-by-step explanation:

in order to evaluate for the value of x in the equation 5( 4x + 2) + 10 = 25

we are going to open the bracket the combine the like terms together and evaluate.

solution

5 (4x + 2) + 10 = 25

20x + 10 + 10 = 25

combine the like terms

20x = 25 - 10 -10

20x = 5

divide both sides by the coefficient of x

20x/20 = 5/20

x = 1/4

therefore the value of x in the expression 5 4x + 2) + 10 = 25 is evaluated to be 1/4

A truck with 36-in.-diameter wheels is traveling at 55 mi/h.

kkurt [141]

Answer:

The angular speed is 3,227 rad/min

Step-by-step explanation:

Remember that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

The circumference is equal to

$C=\pi D$

we have

$D=36\ in$

substitute

$C=\pi (36)$

$C=36\pi\ in$

step 2

we know that

The speed of the wheel is 55 mi/h

Convert to mi/min

55 mi/h=55/60 mi/min

Convert to in/min

(55/60) mi/min=55*63,360/60 in/min= 58,080 in/min

we know that

The circumference of the wheel subtends a central angle of 2π radians

using proportion

Find out how much radians are 58,080 inches

$\frac{36\pi }{2\pi }=\frac{58,080}{x} \\\\x=2*58,080/36\\\\x=3,226.67 \ rad$

therefore

The angular speed is 3,227 rad/min

1) Consider the sequence:

Ivan

Answer:

1) The 38th term is A. 38

2) The 11th term is D. 3072

3) The 3rd term is C. 34

Step-by-step explanation:

1) I added 2 until I got to the 38th term.

2) I multiplied until I got to the 11th term.

3) I added 3 until i got to the 12th term.

The teacher showed a more complex way to do it but this is just what I did.

I took the quiz, so I know that I got them all correct.
