Based on the calculations, the distance covered by Lea is equal to 336 kilometers.
Given the following data:
Lea's time = 4 hours.Lea's speed = 65 km/h.Hanna's distance = 252 kilometers.Hanna's time = 3 hours.How to calculate speed.Mathematically, speed is given by this formula;
[tex]Speed = \frac{distance}{time}[/tex]
Next, we would calculate Hanna's speed by using the above formula:
[tex]Hanna's\; speed = \frac{252}{3}[/tex]
Hanna's speed = 84 km/h.
For Lea's distance:
[tex]Distance = speed \times time\\\\Distance = 84 \times 4[/tex]
Distance = 336 kilometers.

Find the circumference of the object. Use $3.14 or 22/7
for Pi. Round to the nearest hundredth if necessary.
Answer:
18.84
Step-by-step explanation:
Circumference = 2πd
where d = diameter
the shape given has a diameter of 6
to find the circumference we simply plug in the value of the diameter as well as π into the formula
formula : C = πd
π = 3.14 and d = 6
C = 3.14(6) = 18.84cm
A recipe requires
cup of milk for each à cup of water. How many cups of water are
needed for each cup of milk?
Step-by-step explanation:
Let's set up an algebraic equation to reflect the ratio of milk to water. We know that for every 1/3 cup of milk, we have 1/4 cup of water, so we can take:
1/3*m=1/4*w
How might we make that 1/3 cup into 1 cup of milk? We multiply by 3! What we do to one side we have to do to the other otherwise we change the equation (and break math), so we will multiply both sides by 3.
(1*3)/3*m=(1*3)/4*w
3/3*m=3/4*w
m=3/4w

Answer:
x = 3.75
Step-by-step explanation:
Replace y with the y equation.
So..
4x - 2(x + 1.75) = 4
Answer:
(3.75, 5.5)
Step-by-step explanation:
Adding x (3.75) to 1.75 gives 5.50 (5.5). If this is correct, then 4 x 3.75 + 2 x 5.5 = 4
Please help! I have listed the question below.
Write down letters of the circled points and order them by least to greasiest. You will spell a word that describes y way to compare quantities
One way to compare quantities is with fractional numbers that represent quantities using divided numbers.
What is a fraction?Fractional number is a mathematical concept that refers to a quantity divided by another quantity. Common fractions are made up of: numerator, denominator and dividing line between them (horizontal or oblique bar).
The denominator "b" expresses the number of equal parts that represent the unit.The numerator "a" indicates how many of them are taken.Some examples of fractional numbers are:

Answer:
1. x=22 2. x= 28
Step-by-step explanation:
1. The total of angles in a triangle add up to 180˚.
93+65= 158
180-158=22
This means that x = 22
2. Angles on a straight line add up to 180.
180-125=55
180-83=97
55+97=152
180-152=28
This means that x = 28

You are building a flower bed with a perimeter of 16 feet. The length of the bed is 4 feet longer than the width. What are the dimensions ?
Answer:
Step-by-step explanation:
The perimeter is basically the outline of the shape. The perimeter of a rectangle is given by P=2l+2w, where l is the length and w is the width. Thus, the perimeter of the flower bed would be given by P=2(3n5o)+2(5n5o).
