Answer:

The percent change in Nancy height is 10%

Step-by-step explanation:

Given : when Nancy started middle school, she was 60 inches tall. when she started high school, she was 66 inches tall.

We have to find the percent change in her height.

Percentage change is given by the ratio of the difference in old value and new value to the old value times 100

Mathematically written as

Percentage\ change =\frac{new\ value-old\ value}{Old\ value}\times 100

For the given data,

Old value = 60 inches

New value = 66 inches

Thus, the Percentage change is given as,

Percentage\ change =\frac{66-60}{60}\times 100

Simlify, we have,

Percentage\ change =\frac{6}{60}\times 100

Thus, The percent change in her height is 10%

we can clearly notice that she added 6 inches so we will have to divide 60 By 6
to get the percentage 60 ÷6 = 10%

Is this a right triangle why or why not?
Marysya12 [62]

Answer:

No, it does satisfy the Pythagorean Theorem  

Step-by-step explanation:

In right triangle a² + b² = c²

Where a and b = legs and c = hypotenuse

The given measures of the legs are 3 and 7 and the given measure of the hypotenuse is √57

Which means that if this is a right triangle then 3² + 7² = √57²

3² = 9

7² = 49

√57² = 57

9 + 49 = 58

we're left with 57 ≠ 58 which is not true, meaning that , that is not a right triangle

Helpp me please!!!!!!

Answer:

a. Inscribed angle = <WXY

b. Minor arc = arc(XY)

c. VWX

d. m(VWX) = 180°

e. m<VUW = 110°

Step-by-step explanation:

a. The angle, <WXY has its vertex on the circumference of the circle. Therefore, it can be referred to as an inscribed angle of the circle with center U.

Inscribed angle = <WXY

b. Arc(XY) is a minor arc because it is smaller than half of circle with center U.

Minor arc = arc(XY)

c. A semicircle is half of a full rotation for a circle. From the diagram, a semicircle is VWX

d. m(VWX) = Half the rotation of a full circle = 180°

e. m<VUW = arc(VW) (measure of central angle = measure of arc)

m<VUW = 110° (Substitution)

Who is the father of maths???​
Sphinxa [80]

Answer: Archimedes

Step-by-step explanation:

Archimedes was considered the father of mathematics, simply because he made profound advancements in both science and math. His title is purely a nickname, and not because he actually created math.

Suppose two bicyclists start at the same location.
DerKrebs [107]

Answer:

Step-by-step explanation:

See attachment.

If both cyclists travel for the same time and speed, they will have travelled the same distance.  Since one is headed north and the other east, we can see that the distance between them in one hour is the hypotenuse of a right triangle.  Each leg has distance x.  We can say x^2 + x^2 = (3\sqrt{2})^2

2x^2 =1 8

x^2 = 9

x = 3

They both rode 3 miles.
