A car travels 172 miles using 7 gallons of gas how far can the car travel using 42 gallons of gas?

Answers

Answer 1

Answer:

The required distance that a car travel for 42 gallons of fuel is 1032 miles.

Given that,
A car travels 172 miles using 7 gallons of gas how far can the car travel using 42 gallons of gas is to be determined.

What is rate of change?

Rate of change is defined as the change in value with rest to the time is called rate of change.

here,
Rate of the car = 172 / 7 miles per gallon,
Now,
Distance travel = rate × fuel
= 172/7 × 42 = 1032 miles

Thus, the required distance that a car travel for 42 gallons of fuel is 1032 miles.

How do you triple rhe surface area of a cone

Answers

Increase the height so that the slant height triples.

For example:
Say that lateral height is 2 and the radius is 1. The lateral surface area would be 6.28

if I make the lateral height 6, which is triple the original lateral height, the lateral surface area becomes 18.84, which is triple the original surface area

Solve by completing the square

x^2-6x-16=0

Answers

Answer:

x = 8 or

x = -2

Step-by-step explanation:

Completing The Square:

x² - 6x - 16 = 0

Here,

a = 1

b = -6

c = -16

Now,

x² - 6x + [6/2(1)]² - [6/2(1)]² - 16 = 0

x² - 6x + (6/2)² - (6/2)² - 16 = 0

x² - 6x + (3)² - (3)² - 16 = 0

(x - 3)² - 9 - 16 = 0

(x - 3)² - 25 = 0

(x - 3)² = 25

x - 3 = +-√25

x - 3 = +- 5

x = 3 +- 5

x = 3 + 5 or x = 3 - 5

x = 8 or x = -2

A ball is thrown upward and its height after t seconds can be described by formula f(t)=−10t2+24t+5.6. Find the maximum height the ball will reach.

Answers

Answer:

The maximum height is 20.

Step-by-step explanation:

The height of the ball is given by $f(t)= -10t^(2) +24t+5.6$ .

Differentiating the above equation, with respect to t, we get $(d f(t))/(dt) = -20t + 24$ .

At the maximum height the derivative of the function needs to be 0.

Hence, $(d f(t))/(dt) = 0$ gives $t = (24)/(20) = (6)/(5)$ .

The maximum height is $f((6)/(5) )= -10((6)/(5) )^(2) +24((6)/(5) )+5.6 = 20$

at an animal shelter there are 15 dogs 12 cats 3 snakes and 5 parakeets. what percent of the number of cats is the number of snakes

Answers

percentage of cats
$(# animals)/(#cats) = (100)/(?)$
$(35)/(12)= (100)/(?)$
**cross multiply 12 and 100 which is 1200
**divide 35 into 1200
the answer is 34.3% when rounded

percentage of snakes
$(# animals)/(#snakes) = (100)/(?)$
**cross multiply 3 and 100 which is 300
**divide 35 into 300
$(35)/(3)= (100)/(?)$
the answer is 8.57%
