two cars start at the same point.one travel's north at 65 km/h and the other travel's east at 50km/h.How far are they apart after 30 minutes?

Answers

Answer 1

9514 1404 393

Answer:

  41 km

Step-by-step explanation:

The first car is 32.5 km north after 1/2 hour. The second car is 25 km east after 1/2 hour. The Pythagorean theorem tells you the straight-line distance between them:

  d = √(32.5² +25²) = √1681.25 ≈ 41.00

The cars are about 41 km apart after 1/2 hour.

Stella and brain each heat up a small pizza.stella cuts her pizza into 4 equal slices. Brain cuts his pizza into 8 equal parts,Stella eats two pieces of her pizza Brian eats four pieces of his pizza do they eat the same amount of pizza? PLEASE ANSWER!!!!

Answers

Answer:

They are the same amount of pizza.

Step-by-step explanation:

    Stella cut her pizza into 4 pieces. If she eats 2 pieces, then she has eaten half of her pizza. Likewise, Brian cut his pizza into 8 pieces. If he eats 4 pieces, then he has eaten half of his pizza. Therefore, they have both eaten the same amount of pizza.

j is -18

Step-by-step explanation:

The solution is j = -18 for the expression -108π = 6πj

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

Operators who let do basic mathematical calculations.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that the expression

⇒ -108π = 6πj

Divided by 6π both sides

⇒ -108π/6π  = 6πj/6π  

⇒ -18  = j  

⇒ j = -18

Thus, the solution is j = -18 for the expression -108π = 6πj

6 pounds of apples cost $12 how much do 8 pounds cost?

Answers

since 6 lbs of apples cost $12, 1 lb will cost $2.
8 times 2 = 16
8 lbs of apples cost $16

hope this helps!!

Answer:

8=$16

Step-by-step explanation:

6=$12

divide both sides by 6

1=$2

so one pound equals $2 so if 6 pounds equals $12 just add 2 pounds to 6 to make it 8 pounds. you added two pounds so that means you have to add $4 to the total witch will give you

8=$16

A. 2
B. 3
C. 4
D. 5

Answers

The answer is 4! So c

Using function concepts, it is found that the degree of the function is: 4, option C.

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

The x-intercepts of a function are the values of the function for which the output is zero.The degree of a function is the sum of the multiplicities of the x-intercepts of the function.If a function has a complex root, it means that the conjugate is also a root.

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

When [tex]x = -5, h(x) = 0[/tex], thus, x = -5 is one x-intercept.When [tex]x = 4, h(x) = 0[/tex], thus, x = 4 is one x-intercept.There is also a x-intercept(zero) at [tex]x = 2 - 5i[/tex]. There will also be a x-intercept at the conjugate, which is [tex]x = 2 + 5i[/tex].Thus, there are 4 x-intercepts, all with multiplicity 1, which means that the degree of h(x) is 4, option C.

Now, let’s use those clues to transform these words into an equation.

“5 times a number” means 5 multiplied by a variable: 5x

“And” means adding: 5x+6

“Is equal to 7” means put an equal sign, and then 7: 5x+6=7
