the ratio of a shorter walkway to a longer walkway is 3 to 5. the lenght of the sorter walkway is 45 meters. what is the lenght of the longer walkway
Answer:
75 mStep-by-step explanation:
Let s- shorter walkway, l- longer walkway.
Given:
s/l = 3/5s = 45 mFind the length of l:
45/l = 3/5l = 45*5/3l = 75 mAnswer:
[tex]\sf\longmapsto \: length = 75 \: metres[/tex]
Step-by-step explanation:
Now let's find out what's the length of the long walkway–
[tex]\sf\longmapsto \: \frac{3}{5} = \frac{45}{\: length\: of \:longer\: walkway} [/tex]
[tex]\sf\longmapsto \: \: length\: of \:longer\: walkway= \frac{45 \times \: 5 }{3} [/tex]
[tex]\sf\longmapsto \: length\: of \:longer\: walkway= 75 \: metres[/tex]
The length of the longer walkway is [tex]\sf\longmapsto \: length = 75 \: metres[/tex]

the circumcenter of a triangle is equidistant from the
Answer:
The circumcenter of a triangle is a point that is equidistant from all three vertices. The circumscribed circle is a circle whose center is the circumcenter and whose circumference passes through all three vertices.
Step-by-step explanation:
We can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.
What is the Circumcenter of a Triangle?The circumcenter of a triangle can be said to be a point where all three perpendicular bisectors of the sides of the triangle intersect. At this point, all three vertices of the triangle are equidistant.
This means that, each vertices are far from the circumcenter at equal distance.
Therefore, we can conclude that the circumcenter of a triangle is equidistant from the three vertices of the triangle.

How many square yards of carpet are needed to cover the floor of a related 15 feet long and 12 feet wide
Answer:
20 yards squared.
Step-by-step explanation:
First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.
The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.

The statement below describes a situation in which opposite quantities combine to make zero:
A cup with a hole in it loses 2 ounces of water in the first minute and then loses 2 ounces of water in the second minute.
True
False
Answer: False
Step-by-step explanation:
A cup with a hole in it loses 2 ounces of water in the first minute. This mathematically means
Add -2 (loses ⇒ means getting less)
Then the cup loses 2 ounces of water in the second minute. This mathematically means
Add -2 (loses ⇒ means getting less)
In total, and means loses 4 ounces in two minutes.
Thus, the statement below does not describe a situation in which opposite quantities combine to make zero, so this statement is false

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
How fast did Car B travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Answer:
60mph
Step-by-step explanation:
2s - 30 = 1.5s
2s - 1.5s = 30
.5s = 30
s = 60 mph is car B's speed

Joshua finds the perimeter of the following composite figure composed of a square and right triangle so that a braid may be cut around its outer edge. Determine what is wrong with his calculations and how to find the correct length.
The perimeter of a shape is the sum of its side lengths.
Joshua miscalculated the third length of the triangle
First, we calculate the third length (x) of the triangle.
Because the triangle is right-angled, we can make use of Pythagoras.
So we have:
[tex]x^2 = 7^2 + 7^2[/tex]
[tex]x^2 = 2(7^2)[/tex]
Take square roots of both sides
[tex]x = \sqrt{2(7^2)[/tex]
[tex]x = 7\sqrt{2[/tex]
The other shape in the figure is a square.
So, the perimeter (P) is
[tex]P = 7 + x + x + x + 7[/tex] ---- i.e. the sum of the visible lengths
So, we have:
[tex]P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7[/tex]
Evaluate like terms:
[tex]P = 14 + 21\sqrt2[/tex]
Hence, Joshua's error is that:
He miscalculated the third length of the triangle

look at the time for example, B's time is constant because it isn't skipping numbers like 1, 5, 3,etc.
the height is also constant because it is dividing each number by 2, 60÷2=30, 30÷2=15, 15÷2=7.5. You will notice A is not constant so (no) but B is so (yes)
