Time = distance / speed
Time = 18 km / 6 know
Time = 3 hours
Answer:
[tex] \bf \huge 3 \: hours[/tex]
Step-by-step explanation:
Given that :Dorcas walks a distance of 18 km from home to school at a speed of 6km/h.to find :how long does she take to arrive at school ?formulas used :time = distance / speedlet us assume :time = texplanation :⟼ distance = 18 km
⟼ speed = 6 km/h
⟼ t = distance / speed
⟼ t = 18/6 h
⟼ t = 3h
⟼ time = 3 hours.
∴ dorkas take 3 hours. to arrive at school.

show that triangle BCD is isosceles
Step-by-step explanation:
∠BAC = ∠BCA because it is an isosceles triangle
∠ADB = ∠ABD = 72° because it is an isosceles triangle
∠BAD = 180° - 72° - 72° = 36° because the sum of all interior angles in a triangle = 180°
∠BDC = 180° - 72° = 108° because it is supplementary to 72°
∠ABC = 180° - 36° - 36° = 108° because the sum of all interior angles in a triangle = 180°
∠DBC = 108° - 72° = 36° (∠ABC - ∠ABD)
since ∠DBC = ∠DCB, ΔBCD is isosceles

= $347.90 + $17 + $84 + $64.40 + $33.50 + $98.25 + $17.44 + $79.87
= $742.36
hence, the total monthly cost is $742.36

Two trapeziums are similar, thee area of one of the trapezium is 4times that of the other. Determine the ratio of the perimeter & the corresponding side length of the trapezium
Answer:
The ratio of the perimeters of the two trapezium is 2
The ratio of the corresponding sides of the two trapezium is 2
Step-by-step explanation:
The given parameters in the question are;
Two trapeziums are similar
The area of one trapezium = 4 × The area of the other trapezium
Let, A₁, and A₂ represent the area of the two trapeziums, we have
A₁ = 4 × A₂
∴ A₁/A₂ = 4
Given that ratio of areas = (Ratio of sides)²
Ratio of sides = Ratio of perimeter
∴ Ratio of areas = (Ratio of perimeter)²
Therefore, given that the ratio of the areas of the two trapeziums A₁/A₂ = 4, we have;
Ratio of areas = 4 = (Ratio of sides)²
The ratio of the corresponding sides = √4 = 2
The ratio of the corresponding sides = 2
Ratio of areas = 4 = (Ratio of perimeter)²
The ratio of the perimeter = √4 = 2
The ratio of the perimeter = 2
Answer:
The ratio of the perimeters of the two trapezium is 2
The ratio of the corresponding sides of the two trapezium is 2
Step-by-step explanation:
The given parameters in the question are;
Two trapeziums are similar
The area of one trapezium = 4 × The area of the other trapezium
Let, A₁, and A₂ represent the area of the two trapeziums, we have

∴ Ratio of areas = (Ratio of perimeter)²
Therefore, given that the ratio of the areas of the two trapeziums A₁/A₂ = 4, we have;
Ratio of areas = 4 = (Ratio of sides)²
The ratio of the corresponding sides = √4 = 2
The ratio of the corresponding sides = 2

The ratio of the perimeter = √4 = 2
The ratio of the perimeter = 2

So answer is 120.
Lara borrowed $4500 for some home repairs. She will be paying 6% in simple interest over the next three years. What is the total amount she will be paying on the loan
Answer:
5310
Step-by-step explanation:
6% of 4500=270
270x3years=810
4500+810=5310
Lara will be paying the total amount is $5310
What is simple interest?Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Given that, Lara borrowed $4500 for some home repairs. She will be paying 6% in simple interest over the next three years.
We need to find the total amount she will be paying on the loan,
So, the formula for simple interest is - SI = PRT / 100
P = principal, r = rate and t = time
Therefore,
SI = 4500 x 6 x 3 / 100
= 45 x 18 = 810
The interest = $810
She will pay = interest + principal = 810 + 4500 = $5310
Hence, Lara will be paying the total amount is $5310

Answer:
Milk
Step-by-step explanation:
The amount of milk, cottage cheese and strawberries used are given in the attached picture.
3/4 cup of milk
2/6 cup cottage cheese
8/12 cup strawberry
Converting the fractions to decimal :
3/4 cup of milk = 0.75
2/6 cup cottage cheese = 0.3333
8/12 cup strawberry = 0.66666
0.75 > 0.6666 > 0.3333
We can conclude that amount of milk is greatest, then strawberry and the least is cottage cheese.
