A boat traveled 37 miles in 2 hours. At this rate, how many miles will the boat travel in

Inessa [10]

Answer:

i. The boat will travel 18.5 miles in one hour

ii. The boat will travel 9.25 miles in half an hour

iii. The boat will travel 27.75 miles in one and a half hours

Explanation:

We are given that the boat travel 37 miles in 2 hours

To get the miles traveled, we can simply use cross multiplication

i. Miles traveled by the boat in one hour:

37 miles .....................> 2 hours

x miles ........................> 1 hour

$x = \frac{37*1}{2}=18.5$ miles

ii. Miles traveled in half an hour:

37 miles .....................> 2 hours

x miles ........................> 0.5 hour

$x = \frac{37*0.5}{2}=9.25$ miles

iii. Miles traveled in an hour and a half:

37 miles .....................> 2 hours

x miles ........................> 1.5 hour

$x = \frac{37*1.5}{2}=27.75$ miles

Hope this helps :)

Darryl and Kayla sold pies for a school fundraiser. Darryl made $38 from 2 chocolate pies and 4 apple pies. Kayla made $138 from

katrin2010 [14]

Answer:

Step-by-step explanation:

let the cost of apple pie be $x$ and the cost of chocolate pie be $y$ .

We then express the situation as:

$2y+4x=38\ \ \ \ \ \ ...eqtn1\\\\14y+12x=138\ \ \ \....eqtn2$

#Make y the subject of the formula in equation 1 then substitute in 2:

$2y=38-4x\\y=19-2x\\\\\therefore 14(19-2x)+12x=138\\\ \ 266-28x+12x=138\\\ \ 128=16x\\x=8\\\\y=19-2\times8=3$

Hence, the cost of a chocolate pie is $3

Which statements are true? Mark all that apply. A If y3 5 27, the value of y is 3. B If y3 5 64, the value of y is 4. C If y3 5

andreyandreev [35.5K]

Answer:

A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1

Step-by-step explanation:

Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.

Solution:

a) y³ = 27

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛27

y = 3

Option A is correct

b) y³ = 64

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛64

y = 4

Option B is correct

c) y³ = 1

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛1

y = 1

Option C is correct

d) y³ = 16

To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:

∛y³ = ∛16

y = 2.52

Option D is wrong
