There are 37 tens in the cash register

EXPLANATION

Given that;

The total amount in the cash register is $740

The cash register contain five dollar and ten dollar

Follow the steps below to find the number of ten dollar in the cash register.

Let x represents the number of $5 and $10 in the cash register.

Recall, that the register contain twice as many $5 as ten dollars and this can be expressed mathematically as

Evaluate x in the above expression

Therefore, we have 37 tens in the cash register

Answer:

11.2 Slices / Week

Step-by-step explanation:

We know that Jake has eaten 5 slices of cake in 3 days. You can divide 5 / 3 to get an average of 1.6 slices of cake being eaten per day. The question asks what the weekly rate or eating the cake will be, do you need to multiple 1.6 x 7 for the total amount of cake eaten per week, which is 11.2 slices!

Answer:

11.6

explanation

we have 7 days.

7days-3days =4

in 3 days he has eaten 5 slices

again 4-3 days=1

so in 6 days he has eaten 10 slices

we have 1 day left.so if he eats 5 slices in 3 day,how many he eat slices in 1 day?5/3=1.6

10+1.6=11.6

The velocity is v= 30.6 ft/ sec.

Velocity defines the direction of the movement of the body or the object. Speed is primarily a scalar quantity. Velocity is essentially a vector quantity. It is the rate of change of distance. It is the rate of change of displacement.

Given that,

We have given the height

s(t) = 0.2[tex]t^{3}[/tex] + 21t, where 0 ≤ [tex]x[/tex] ≤ 17.

To find the velocity we have to differentiate s(t) wrt to t.

s(t) = 0.2[tex]t^{3}[/tex] + 21t

    = 0.6[tex]t^{2}[/tex]+21

velocity of the particle at t = 4

s(4) = 0.6*[tex]4^{2}[/tex]+21

     = 9.6+21

     = 30.6

v= 30.6 ft/ sec

Hence, The velocity is v= 30.6 ft/ sec.

64 ounces of cherries are displayed in all in the farm stand.

According to the question,

We have the following information:

Farm stand has cherries on 2 shelves.

Number of boxes in each shelf = 4 boxes

So, the number of boxes in 2 shelves will be (2*4) or 8.

Ounces of cherries in each box = 8 ounces

Now, the ounces of cherries in 8 boxes can be easily found by multiplying the ounces of cherries in 1 box by the number of total boxes.

Ounces of cherries in 8 boxes = (8*8) ounces

Ounces of cherries in 8 boxes = 64 ounces

Now, the expression that represents the amount is (number of shelves*number of boxes*ounces of cherries in each box).

Hence, the ounces of cherries displayed in all is 64 ounces.

Answer:

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

The water fountain forms a circle. The distance around the water fountain is the circumference of the circle formed.

Therefore,

circumference = 2πr

150 = 2πr

The distance from the edge of the fountain to the centre is the radius of the circle formed. Therefore,

75 = πr

r = 75 / 3.14159

r = 23.8732616287

r = 23.87 inches

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

Answer:

The interval at which the function is increasing is from x = -2 to x = 0. In interval notation, it is (-2, 0).

Explanation:

See the graph below for the pattern of the function.

As you can see above, from x = -∞ until x = -2, the value of the function decreases from y = +∞ to y = -7.

Then, starting at x = -2 to x = 0, the value of the function increases from y = -7 to y = -3.

Lastly, starting at x = 0 to +∞, the value of the function decreases again from y = -3 to -∞.

Hence, the interval at which the function is increasing is at (-2, 0).

The limit of a function is the value that a function approaches as that function's inputs get closer and closer to some number.

The question asks us to estimate from the table:

To find the limit of g(x) as x tends to -2, we need to check the trend of the function as we head towards -2 from both negative and positive infinity.

From negative infinity, the closest value we can get to before -2 is -2.001 according to the values given in the table. The value of g(x) from the table is:

From positive infinity, the closest value we can get to before -2 is -1.999 according to the values given in the table. The value of g(x) from the table is:

From the options, the closest estimate for the limit is 8.03.

Answer:

It is the diameter of the circle

it is 7 cm

it is a chord

Explanation:

First, we notice that the line segment CB passes through the centre of the circle and its endpoints touch the circumference - this tells us that CB is the diameter.

Furthermore, any line segment whose endpoints lie on the circumference of the circle is a chord (meaning that the diameter is the longest chord), and so we deduce that CB is also a chord.

Since CB is the diamter, its length is 2 times the radius. The raduis of the circle we know is DA = 3.5 cm; therefore, the dimater is CB = 2 DA = 2 * 3.5 = 7 cm.

Hence, the correct choices are:

It is the diameter of the circle

it is 7 cm

it is a chord

The substitution u = (2x - 2) to the integral x³e(^2x^4-2) dx is (2x – 2)/4 +c

Therefore,

Use the substitution

let u = 2x -2

du = x dx or dx =du/2

u = 2x-2

du = d(2x – 2)

du = 2dx

dx = du/2

The single trig function that simplifies the function is sec(t)

Trigonometry deals with the functions of angles and how they're applied.

Given cot(t)/csc(t)-sin(t)

since csc(t) =  1/sin(t) , we have:

[tex]\frac{ cot(t)}{csc(t)-sin(t)} = \frac{cot(t)}{\frac{1}{sin(t)} - sin(t) }[/tex]

[tex]\frac{ cot(t)}{csc(t)-sin(t)} = \frac{cot(t)}{\frac{1-sin^{2}(t) }{sin(t)} }[/tex]

since:

cos²(t) = 1 - sin²(t)

Therefore we have:

cot(t) / csc(t)-sin(t) = cot(t)/ cos²(t)/sin(t)

cot(t) / csc(t)-sin(t) = cot(t) / cos(t).cos(t)/sin(t)

Since  cos(t) / sin(t) = 1/tan(t) = cot(t)

Therefore:

cot(t) / csc(t)-sin(t) = cot(t)/ cot(t)×cos(t)

cot(t) / csc(t)-sin(t) = 1/cos(t)

Since   1/cost = sec(t)

Finally, cot(t) / csc(t)-sin(t) is sec(t).

Let's use the variable x to represent the amount of pure acid and y to represent the amount of 10% acid.

Since the total amount wanted is 90 L, we can write the equation:

Also, the final solution is 81%, so we can write our second equation:

From the first equation, we can solve for y and we will have y = 90 - x.

Using this value in the second equation, we have:

Solving for x, we have:

Therefore the amount of pure acid to be used is 71 L and the amount of 10% acid is 19 L.

- The amount a person is paid per hour in wages is the amount that the person collects for every hour that he works

- Let us imagine that a person receives $a for every hour worked.

- This means that:

After 1 hour, the person makes $a

After 2 hours, the person makes $a + $a = $2a

After 3 hours, the person makes $a + $a +$a = $3a

- We can therefore generalize as follows:

Simple interest is represented by the following expression:

We need to create a system of equations:

Let x be the money invested in the account that paid 6%

Let y be the money invested in the account that paid 10%

So, he received a total of $920 in interest, then:

And we know that money invested must add together $10,000:

Then, we can isolate y in equation (2):

Now, let's substitute y=10,000-x in the equation (1):

That means, he invested $2,000 in the account that paid 6% simple interest. Now, having x, we are going to substitute x in the second equation (2):

He invested $8,000 in the account that paid 10% simple interest per year.
