A wheel has a radius of 15 cm. Approximately how far does it travel in 4 revolutions?47.1 cm

94.2 cm

188.4 cm

376.8 cm

Answers

Answer 1

Answer: Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D

What is the complement of the angle 178 degrees and 100 degrees

Answers

$Complement - x \n \n 178 + x = 90 \n \n x = 90-178 = -88. \n\n\nComplement-y \n \n 100 + y = 90 \n \n y = 90-100 = -10$

Thus, the complement of 178 is -88 degrees and complement of 100 is -10.

$The\ complement\ of\ an\ angle\ \alpha \ is\ the\ angle\ 90^0- \alpha .\n\n \alpha =178^0\ \ \ \Rightarrow\ \ \ 90^0- \alpha =90^0-178^0=-88^0\n\n\alpha =110^0\ \ \ \Rightarrow\ \ \ 90^0- \alpha =90^0-110^0=-20^0$

The Joneses are moving from San Francisco to South Africa. They pack their belongings in rectangular crates and hire a boxcar to ship the crates across land and sea. The crates are made specifically to fit inside the boxcar with their bases facing down. Each crate has a base 15 ft long by 5 ft wide and height 6.5 ft. The boxcar is 60 ft long, 10 ft wide and 13 ft high. How many crates can The Joneses fit into one boxcar?

Answers

La sup della base del box e' :
S box=60 x10=600
S crate =15 x5=75
Sulla base del box si possono mettere 600/75=8 crate
Sull' altezza (high) si possono mettere 13/6,5=2 strati
8( crate/ strato) x 2 (strati)=16 crates

Answer:

16 crates if i am right

A bag of chips costs $3.79 including tax Mr.Connor wants to purchase chips for his class and has a $15 budget. Write and inequality to solve for the number of bags of chips Mr.Connor can purchase with his budget A. $15x > $3.79 B.$15x < $3.79 C $3.79 > $15 D. $3.79 < $15 (There is a flat line under all the greater than and less than signs)

Answers

The inequality equation that could best express the statement will be letter d. 3.79x < 15. This is because there is only 15 budget from Mr. Connor, and his spending must not exceed the budget. Then the price per pack is 3.79, so it is express as 3.79x.

Answer:

D. $3.79x\leq 15$
