Answer with explanation:

According to Pythagorean Theorem if in a right triangle the two legs of a right triangle are a and b and the hypotenuse is denoted by c then we have:

          c^2=a^2+b^2

Ques 1)

By Pythagorean Theorem we have:

                 (440)^2=(305)^2+a^2\\\\i.e.\\\\193600=93025+a^2\\\\\\a^2=193600-93025\\\\\\a^2=100575\\\\\\a=317.1356\ units

To the nearest tenth we have:   a=317.1

Ques 2)

By Pythagorean Theorem we have:

                 (415)^2=(390)^2+b^2\\\\i.e.\\\\172225=152100+b^2\\\\\\b^2=172225-152100\\\\\\b^2=20125\\\\\\b=141.8626\ units

To the nearest tenth we have:   b=141.9

Ques 3)

By Pythagorean Theorem we have:

c^2=(625)^2+(450)^2\\\\\\c^2=593125\\\\\\c=770.1460

To the nearest tenth we have:   c=770.1

Ques 4)

By Pythagorean Theorem we have:

(515)^2=(380)^2+d^2\\\\\\d^2=120825\\\\\\d=347.5989

To the nearest tenth we have:   d=347.6

Ques 5)

By Pythagorean Theorem we have:

(700)^2=(400)^2+e^2\\\\\\e^2=330000\\\\\\e=574.4562

To the nearest tenth we have:  e=574.4

Ques 6)

By Pythagorean Theorem we have:

(750)^2=(500)^2+f^2\\\\\\f^2=312500\\\\\\f=559.0169

To the nearest tenth we have:   f=559

Ques 7)

By Pythagorean Theorem we have:

(g)^2=(250)^2+(250)^2\\\\\\g^2=125000\\\\\\g=353.5533

To the nearest tenth we have:   g=353.6

Ques 8)

By Pythagorean Theorem we have:

(400)^2=(325)^2+h^2\\\\\\h^2=54375\\\\\\h=233.1844

To the nearest tenth we have:   h=233.2

Ques 9)

By Pythagorean Theorem we have:

(i)^2=(300)^2+(400)^2\\\\\\i^2=250000\\\\\\i=500

To the nearest tenth we have:   i=500

Ques 10)

A Pythagorean triple is the set of three positive integers a,b and c such that it satisfy:

                  c^2=a^2+b^2

Hence, we among the given above options the Pythagorean triple are:

 The last option form i.e. the triangle whose side is 300, 400 and i.

Also, the figure is attached to the answer.

Cable has 24 pennies he has hafe as many nickels as pennies he has 5 more dimes than nickels he has 6 fewer quarters than dimes
Andreyy89
Pennies (P) = 24
Nickels = 1/2P
Dimes = 1/2P + 5
Quarters = (1/2P + 5) -6

Therefore...

Nickels = 1/2P = 1/2(24)= 12
Dimes = 12 + 5 = 17
Quarters = 17 - 6 = 11

vaieri [72.5K]

Step-by-step explanation:

This can be modeled by the equation f(x)=7+5x

Because if f(1)=7+5=12, f(2)=7+10=17, and f(x)=7+15=22

If x=50 then f(50)=7+5(50)

f(50)=$257

Express 16 as a difference of two prime numbers
sasho [114]
16 can be expressed as a difference of two prime numbers in two ways, which is:23 - 7 = 16, 19 - 3 = 16
Among the choices, 16 is expressed as (23 - 7), which is the difference of two prime numbers.

GEOMETRY PROBLEMS PLEASE HELP ME
SIZIF [17.4K]

Answer:

12) The measure of PQR is 36 since both angles MQP (25) and PQR should add up to MQR (61)

13) The graph shows that both angles are congruent so that means:

2x+8= x+22

2x= x+14

x=14

14) angle ADB and angle BDC since it shows that both angles sum up to 90 degrees (also known as complementary angles)

15) Angles ADE and angle FDE are supplementary because they both add up to 180 degrees (supplementary angles)

16) Angles ADC and FDE are vertical because they are opposite of each other

17) Angles ADE and FDE are also linear pairs because both of them are adjacent (they both have a common side as well as a common vertex)

Hope this helps! ;)
