Jacob and issac decided to run to the basketball court after school the basketball court is 5 1/4 Miles from school the boys run

GenaCL600 [577]

Answer: $1\dfrac{5}{9}\text{ minutes}$

Step-by-step explanation:

Complete question is provided in the attachment below.

Given: Jacob and Issac decided to run to the basketball court

Distance between basketball court and school = $5\dfrac{1}{4}$ miles

$=\dfrac{21}{4}$ miles

Speed = $3\dfrac{3}{8}$ miles per hour

$=\dfrac{27}{8}$ miles per hour

Since, time = (distance) ÷ ( speed)

Now, the time taken by boys to arrive at the basketball court = $\dfrac{21}{4}\div\dfrac{27}{8}$ hours

$=\dfrac{21}{4}\times\dfrac{8}{27}\\\\=\dfrac{7\times2}{9}=\dfrac{14}{9}\\\\=1\dfrac{5}{9}\text{ minutes}$

Hence, the required length of time = $1\dfrac{5}{9}\text{ minutes}$

The value pi/24 is a solution for the equation 4 cos^4 (4x)-3

MatroZZZ [7]

Answer:

False

Step-by-step explanation:

4 cos^4 (4x)-3 = 0

Substitute into the equation

4 cos^4 (4pi/24)-3 = 0

4 cos^4 (pi/6)-3 = 0

Take the cos pi/6

4 ( sqrt(3)/2) ^4 -3 =0

Take it to the 4th power

4 ( 9/16) -3 =0

9/4 -3 =0

9/4 - 12/4 = 0

-3/4 =0

False
