6 erasers cost $6.60. Which equation would help determine the cost of 3 erasers?

2 answers:

6 0

First 6.60 divided by 6 to find the unit rate. It is 1.10 dollars per eraser. You then do 1.10 times 3 which will get you 3.30 dollars for 3 erasers.

Answer with Step-by-step explanation:

We are given that:

6 erasers cost $6.60.

We have to find:

The cost of 3 erasers

Cost of 6 erasers =$ 6.60

Cost of 6/2 erasers= $6.60/2

i.e. cost of 3 erasers= $3.30

Equation which determine the cost of 3 erasers is:

Cost of 6/2(=3) erasers= $6.60/2=$3.30

June and Armando are each in a hot air balloon. Armando's balloon is at a slightly higher elevation than June's. The two balloon

Mandarinka [93]

Answer:

46.63 ft

Step-by-step explanation:

I've drawn and attached a triangle diagram to represent this elevation and distance of balloons.

Now, from the diagram attached, we can see the angle at which June must look up to see Armando is 25°.

Also, the height of Armando above June is represented by "x".

Thus, using pythagoras theorem, we can find x.

Thus;

x/100 = tan 25

x = 100 × tan 25

x = 100 × 0.4663

x = 46.63 ft

This is so confusing all of it makes no sense

Answer:

D). $4\sqrt{2}$

Step-by-step explanation:

STEP 1a: Find the last angle of the triangle. ( which is angle A)

$A+90+45=180$

STEP 1b: Solve the equation for A by adding 90 and 45.

$A+135=180$

STEP 1c: Then Move all terms not containing A to the right side of the equation by subtracting 135 from both sides of the equation

$A=180-135$

STEP 1d: Subtract 135 from 180.

$A=45$

STEP 2a: Find side b next.

STEP 2b: The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.

$cos(A)=\frac{adj}{hyp}$

STEP 2c: Substitute the name of each side into the definition of the cosine function.

$cos(A)=\frac{b}{c}$

STEP 2d: Set up the equation to solve for the adjacent side, in this case b.

$b=c*cos(A)$

STEP 2e: Substitute the values of each variable into the formula for cosine.

$b=8*cos(45)$

STEP 2f: Cancel the common factor of 2.

$a=4\sqrt{2}$
