the quotient of n and 2 is 6 times n

Answer:

$6

Step-by-step explanation:

A=P(1+i.n)

A=200(1+0.01.x 3)

A=206

Thus 206 - 200 = $6

You will earn $6 in interest.

The interest you will earn per year is:

= Interest rate x Amount deposited

= 200 x 1%

= $2

Because it is simple interest, you will earn the same amount of interest every year. In 3 years you will have:

= Interest per year x number of years

= 2 x 3

= $6

You will therefore earn $6 in interest.

The total number of pots will be 1¹/₄.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that at lunchtime, a cafeteria served a total of 3/8 of a pot of chicken soup and 7/8 of a pot of onion soup.

The total number of pots will be calculated as:-

E = 3/8 + 7/8

E = 10 / 8

E = 5 / 4

E = 1¹/₄

Hence, the total number of pots will be 1¹/₄.

Answer:

The probability of picking a yellow marble is 2/13

Step-by-step explanation:

First of all, we need to know the total number of marbles that are in the bag. To do this, we will have to add up all the marble colors together.

This will give us 6 + 2 +4+ 1 = 13 marbles in total.

The next step is to find the number of yellow marbles in the bag.

We can get this from the question. There are 2 yellow marbles in the bag.

The probability of selecting a yellow marble can be obtained by dividing the number of yellow marbles by the total number of marbles in the bag

This will give us 2/13.

Therefore, the probability of picking a yellow marble is 2/13

[tex]E = 30 \times H[/tex]

$570

Step-by-step explanation:

Given that:

For each hour of tutoring, Lena earns 30 dollars.

E is her earning and

H is the number of hours for which she tutors.

To find:

Equation relating E to H.

Solution:

Let Lena tutors for 1 hour, then the earning = 30 dollars

Let Lena tutors for 2 hours, then the earning = 30+30 OR 2[tex]\times[/tex]30 = 60 dollars

Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 3[tex]\times[/tex]30 = 90 dollars

If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.

[tex]E = 30 \times H[/tex]

So, the equation that relates E to H is given as:

[tex]E = 30 \times H[/tex]

Now, it is given that she tutors for 19 hours.

Let us put H = 19 hours in the above equation:

[tex]E = 30 \times 19 \\\Rightarrow E = \$570[/tex]

Therefore, the earning for 19 hours of tutoring is 570 Dollars.

Angle Q= 180-49 (supplementary angles)

So angle Q= 131

Answer:

49 ft

Step-by-step explanation:

h=−16(t−14)^2+49

The path of the marshmallow is an inverted parabola. It has symmetry with respect to its vertical axis.

We take the derivative of the height function.

dh/dt = -32(t - 14)

dh/dt = -32t + 448

We set the derivative equal to zero ti find the value of t corresponding to a maximum value of h.

-32t + 448 = 0

-32t = -448

t = 14

Maximum height occurs at t = 14 seconds.

h=−16(t−14)^2+49

t = 14

h=−16(14−14)^2+49

h = 49

Maximum height is 49 feet.

Answer:

The total height of the climbing wall is 12 feet

Step-by-step explanation:

The given parameters are;

The star of the climbing wall = On the gym basement

The height of the gym's basement above the ground level = 9 feet

The height to which the wall extends above the ground level = 21 feet

The total height of climbing the wall = 21 - 9 = 12 feet

The start of the climbing wall is at the gym's basement level which is already 9 feet above the ground level, therefore, given the the height of the wall is 21 feet above ground level, with wall situated already at 9 feet above ground level which gives the total height of the climbing wall will be 21 - 9 feet or 12 feet.

Answer:

So it will take them 1 day 6 hours and 39 minutes to paint one small house.

Step-by-step explanation:

Henry can paint 1 small house in 3 days so he can paint 1/3 or .3333 in a day

Ruby can paint 1 small house in 4 days so she can paint 1/4 or .25 in a day

Charlie can paint 1 small house in 5 days so he can paint 1/5 or .2 in a day

Together, that means they pain .3333 + .25 + .2 of a house per day. That's an daily rate of:

.3333 + .25 + .2 = .78333

The portion of the house they clean in x days is .78333x. We'd like to know how long it will take them to paint 100% or 1 of the house. So:

.78333x = 1   Divide each side by .78333

x = 1/.78333

x ≈ 1.277

Let's convert .277 to hours by multiplying by 24

.277 * 24 = 6.65

Let's convert .65 to minutes by multiplying by 60

.65 * 60 = 39

So it will take them 1 day 6 hours and 39 minutes to paint one small house.

Answer:

1.277 days

Step-by-step explanation:

H paint .3333 a day  R paint .25 a day  Charlie paint .2 a day

.3333 + .25 + .2 = .78333

x is number of days to paint.

.78333x = 1  

x = 1/.78333  = 1.277

 1.277 days

Answer: A) x + 4x = 35;  7 large stones and 28 small stones

======================================================

Explanation:

x = number of large stones

4x = number of small stones

x+4x = total number of stones = 35

x+4x = 35 is the equation to solve

-----------

Let's isolate x

x+4x = 35

5x = 35

x = 35/5

x = 7 large stones are needed

4x = 4*7 = 28 small stones are needed
