Answer:
the original speed is 50 km/h
Step-by-step explanation:
Let us assume the original speed be x
and fastest speed be (x+ 10)
Now here apply the time formula
i.e. distance by the speed
Original time = Fastest time
500 ÷ x = 600 ÷ x + 10
Now do cross multiplication
600x = 500(x + 10)
600x = 500x + 5000
100x = 5000
x = 50 km/h
Hence, the original speed is 50 km/h

An architect is making a plan for a new circular playground. If the picture below is the
playground, how much fencing needs to go up to
keep the kids in the circle?
Answer:
201ft
Step-by-step explanation:
The circumference of a circle is equal to
C=piD
d=64ft
substitute:
c=pi(64)=64pift ft
assume pi=3.14
64pi=64*3.14=200.96ft
round to the nearest whole number:
200.96=201ft
another explanation:
Answer:
Length of the fencing required = 201.06 meters
Step-by-step explanation:
Architect is planning a circular playground with diameter = 64 m
We have to calculate the fencing required to cover this playground.
Length of fencing = circumference of the playground
Since circumference of a circle = π × (Diameter)
= 64π
= 201.06 meters
Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
200.96 meters of fencing needs to go up to keep the kids in the circle. Therefore, option D is the correct answer.
What is circumference of a circle?The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.
Given that, diameter of a circle is 64 meter.
Here, the radius = 64/2
= 32 meter
We know that, the circumference of a circle can be calculated using 2πr.
Now, circumference = 2×3.14×32
= 200.96 meters
Therefore, option D is the correct answer.

Emily enters a bike race for charity her mother pledges 10 cents for every 0.75 mile she bikes if Emily bikes 15 miles how much will her mom donate
Answer:
The answer is that her mom will donate $2.
Step-by-step explanation:
From the information given, you can use a rule of three to find the amount her mom will donate if Emily bikes 15 miles given that her mother pledges 10 cents for every 0.75 miles:
0.75 miles → 0.10
15 miles → x
x=(15*0.10)/0.75
x= 2
According to this, the answer is that her mom will donate $2.

9. If the area of square 1 is 250 units?, and the area of square 3 is
120 units, what is the area of square 2? Explain your reasoning.
Answer:
185 units.
Step-by-step explanation:
So first, I subtracted: 250 - 120 = 130
I divided 130 by 2. I got 65.
I subtracted 65 from 250 and I got 185.
Proof it is correct:
185 - 120 = 65
AND
250 - 185 = 65

I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am positive and prime. What number am i?
Answer:
2, 3, 5, 7, 11, 17, 19, 23
Step-by-step explanation:
The segment between - 15 and 25 has 40 numbers given by
25 - -15
= 25 + 15
= 40
Divided into 4 segments, each would contain 10 numbers such that the
1st segment is from -15 to -5 (which is -15 + 10)
2nd segment is from -5 to 5 (which is -5 + 10)
3rd segment is from 5 to 15 (which is 5 + 10)
4th segment is from 15 to 25 (which is 15 + 10)
Given that the unknown number is prime and positive this may be
2 or 3 or 5 from the 2nd segment
7 or 11 from the third segment
17 or 19 or 23 from the 4th segment

If two angles are supplementary, their sum equals
A)
45°
B)
90°
180°
D)
360°
Answer:
180°
Step-by-step explanation:
Supplementary angles are two angles whose sum is equal to 180∘. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees. These two angles are supplementary because together they form a straight line.

A. -9/2
B. 1
C. 9/4
D. 5/2
Answer:
9/4
Step-by-step explanation:
2(x - 10) + 4 = -6x + 2
2x - 20 + 4 = -6x + 2
2x - 16 = -6x + 2
8x - 16 = 2
8x = 18
x = 18/8 or 9/4
Answer:
the answer is C
Step-by-step explanation:
2(x-10) +4 = -6x + 2
2x-20 +4= -6x +2
2x-16 = -6x+2
+16 = +16

A farmer has a field in the shape of a semicircle of diameter 50 m. First,
calculate the length of the semicircle to 1 decimal place.
50 m
Answer:
157.1 m
Step-by-step explanation:
Here, we want to calculate the length of the semi-circle
This simply refers to the circumference of the semi-circle
Mathematically, the circumference is half that of a full circle
The circumference of a full circle is;
C = pi * d
For half circle or semi-circle;
It is ;
C = (pi * d)/2
D = 50 m
The circumference is thus;
C = 50 * 3.142
C = 157.1 m

Answer:

The triangles with equal sides from least to greatest
Equilateral, Isosceles, Scalene.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The reason for this order is that an equilateral triangle has all three sides equal in length, while an isosceles triangle has two sides equal in length and one side different.
A scalene triangle has all three sides of different lengths.
Since all three sides of an equilateral triangle are equal, it has the smallest perimeter of the three types of triangles.
The isosceles triangle has two sides equal, so its perimeter will be greater than that of an equilateral triangle, but less than that of a scalene triangle.
Finally, the scalene triangle has three sides of different lengths, so it will have the largest perimeter of the three types of triangles.
Thus,
The triangles with equal sides from least to greatest
Equilateral, Isosceles, Scalene.
