Answer:

Part A: yes

Part B: yes

Part C: yes

Step-by-step explanation:

Part A:

77² + 420² = 427²

5,929 + 176,400 = 182,329

182,329 = 182,329

---------------------------------------------------------

Part B:

279² + 440² = 521²

77,841 + 193,600 = 271,441

271,441 = 271,441

----------------------------------------------------------

Part C:

39² + 760² = 761²

1,521 + 577,600 = 579,121

579121 = 579,121

Answer:

1/2 ft

Step-by-step explanation:

Skylar's speed was ...

(65 ft)/(5 s) = 13 ft/s

Rodrigo's speed was ...

(108 ft)/(8 s) = 13.5 ft/s

Rodrigo traveled farther by (13.5 -13) = 0.5 ft per second.

A grocery store has a shelf with half-gallon containers of milk. What type of number best represents the total number of gallons

Veronika [31]

As a number, half-gallon can be represented as 0.5.
In order to answer this question we will define each term:

whole numbers are numbers that can be defined as a number without fractions which are greater or equal than 0. E.g. 2 0 1 5 6 85

integer numbers are numbers that can be defined as a number without fractions but which can be either equal to 0 or greater and lower than 0
E.g. -9 -68 8 0 59

rational numbers are any number that can be expressed as a fraction p/q of two integers E.g. 0.5 = 1/2 1 = 1/1 1.25 = 5/4

irrational numbers are those which have an approximate value E.g. pi = 3.14...
√2 = 1.41.....

real numbers are all of the above

From all those kind of choices the most accurate representation is rational numbers.

What is the value of x? sin(x+21)°=cos(2x+21)°

qaws [65]

We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90°

in this problem
(x+21)+(2x+21)=90-------> 3x+42=90-------> 3x=48-----> x=16°

What is the value of x in 7(3x - 13)=224 ? Will mark brainliest!

coldgirl [10]

7(3x-13)=224

21x-91 = 224

21x = 315

x = 315 / 21

x = 15

Find the x intercepts for the parabola defined by the equation below. y=x^2-9x+18

givi [52]

X intercepts are where the y value is 0. So, set y=0 and solve
0=x^2-9x+18
0=(x-6)(x-3)
x=6,3
The x intercepts are (6,0) and (3,0)
if you want to check, try these (x, y) pairs in the original equation.
