Solve the following equation : x^2+3√x+16=0

answer: about 22.67

step-by-step explanation:

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.

step-by-step explanation:

for part a. the answer is 5 miles in a hour. in part b. the answer is 10 miles in a hour. sandra runs a mile in 6 minutes while tall runs a mile in 12 minutes

we are given dimensions of the sketch :

length = 12 inches.

width = 18 inches.

given scale factor = 0.2.

the actual dimensions of the mural would be: the sketch dimensions divide by scale factor.

(because the mural would be larger than the sketch dimensions).

we need to find the actualy length of the mural.

therefore,

the length of the mural = 12 inches ÷ 0.2 = 60 inches.
