Answers

Answer 1

Answer:

8/12

Step-by-step explanation:

Given that:

Dividing into 12 steps

Total step, fraction = 1

Each of the 12 steps = 1/12

If two steps is completed in one day:

. Steps completed per day :

2 (1/12)

= 2 /12 steps per day

Fraction of steps completed after 4 days

Fraction of steps per day * number of days

2 /12 * 4

(4*2) / 12

8/12

Whenever you multiply two terms with the same base, you _________ the base and ___________ the exponents.
Example:

Answers

Answer:

Whenever you divide two terms with the same base, you keep the base and subtract the exponents.

Example:

x³ / x⁷ = x³⁻⁷ = x⁻⁴ = 1 / x⁴

or

8¹³ / 8⁶ = 8¹³⁻⁶ = 8⁷

Whenever you multiply two terms with the same base, you keep the base and add the exponents.

Example:

x³ × x⁷ = x³⁺⁷ = x¹⁰

or

12⁻⁵ × 12⁹ = 12⁻⁵⁺⁹ = 12⁹⁻⁵ = 12⁴

Answers

Answer:

Step-by-step explanation:

Let the number of ounces of

A = x

B = y

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?

Our system of equations is given as

x + y = 90.... Equation 1

x = 90 - y

40% × x + 55% × y = 45% × 90 ounces

0.4x + 0.55y = 40.5....Equation 2

We substitute 90 - y for x in Equation 2

Wall-E is sending signals that he is driving into a crater at an angle of depression of 58°. If Wall-E covers a horizontal distance of 130 meters, what vertical distance has it traveled?

Answers

Answer:

208 meters

Step-by-step explanation:

Wall-E is sending signals that he is driving into a crater at an angle of depression of 58°. If Wall-E covers a horizontal distance of 130 meters, what vertical distance has it traveled?

tan θ = Opposite/Adjacent

θ = Angle of depression

Adjacent = Horizontal distance = 130 meters

Opposite = Vertical distance = x

θ = 58°

tan 58 = x/130 meters

Cross Multiply

x = tan 58 × 130 meters

x = 208.04348878 meters

Approximately = 208 meters

Therefore, the vertical distance it travelled is 208 meters

Answers

Answer:

Step-by-step explanation:

We are given with the vertices of the triangle with B(-8,-2)

Please remember the rule of dilation

If a point (x,y) dilated for the scale factor of 'k', we do get image as (kx,ky)

Using this concept, we know scale factor is [tex]\frac{1}{2}[/tex] , we could get image as [tex](\frac{1}{2} (-8), \frac{1}{2} (-2))[/tex]

Let's simplify it

We do get (-4,-1)

metropolis gets 5.8 inches of rain in october, 4.2 inches in novemeber how much does it get in december

Answers

Answer:

2.6

Step-by-step explanation:

Metropolis gets 5.8 inches of rain in October

4.2 inches of rain is seen in November

Therefore the amount that would be seen in December can be calculated as follows

= 5.8-4.2

= 1.6

4.2-1.6

= 2.6

Hence 2.6 inches of rain would be seen in December
