Answer:
Johnny is wrong.
Step-by-step explanation:
To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.
If we choose to use milimeters, we have
600cm=600cm [tex]\frac{10mm}{1cm}[/tex]
600cm = (600)(10) mm
600cm = 6000 mm
Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.
In fact, 6000-5642 mm =358 mm would remain.

Step-by-step explanation:
Mr. Martinez's limo drove 15 miles south to Candy Land for some delicious gumdrops, then 5 miles east to Chuck E. Cheese for some scrumptious pizza. How far is Mr. Martinez from his starting point? Round your answer to the nearest tenth if necessary.
Answer:
15.8 miles
Step-by-step explanation:
Given that:
Distance driven south = 15 miles
Distance driven east = 5 miles
How far is Mr. Martinez from his starting point?
Using Pythagoras :
Distance from starting point(d) :
d = √(15)² + (5)²
d = √225 + 25
d = √250
d = 15.811388
d = 15.8 miles

Determine the value of x in the diagram below
Answer:
x =32
Step-by-step explanation:
create equation
180 = 3x + 20 + 2x
combine like terms
180= 3x + 20 + 2x
180=5x + 20
subtract 20 from both sides of the equation
180=5x + 20
180-20= 5x +20 -20
simplify
160= 5x
divided both sides by 5
160/5=5x/5
solution
32= x

the ratio of 5 more than a number to 20 less than that number is 8:3. What is the number?
Answer:
35
Step-by-step explanation:
Let the number = y ;
5 more than the number = y + 5
20 less than that number = y - 20
Ratio = 8:3;
Solution:
Ratio of the number:
[tex]\frac{y + 5}{ y -20}[/tex] = [tex]\frac{8}{3}[/tex]
Now cross multiply and solve for y;
3(y+5) = 8(y-20)
3y + 15 = 8y - 160
3y - 8y = -160 - 15
-5y = -175
y = 35

A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 2 cups of ingredient A. How many cups of ingredient B do you need?
Answer:
5 3/5 cups of Ingredient B
Step-by-step explanation:
A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 2 cups of ingredient A. How many cups of ingredient B do you need?
This is calculated as:
1/2 cups of Ingredient A = 1 2/5 cups of Ingredient B
This means:
1/2 cups of Ingredient A = 7/5 cups of Ingredient B
2 cups of Ingredient A = x
Cross Multiply
2 × 7/5 = 1/2 × x
x = 2 × 7/5/1/2
x = 2 × 7/5 ÷ 1/2
x = 2 × 7/5 × 2/1
x = 28/5
x = 5 3/5 cups of Ingredient B
Hence, For 2 cups of Ingredient A, 5 3/5 cups of Ingredient B is needed
