Explanation:

We know the final price is $899 and $365 is constant price:

899 = 365 + 89x

We need to find x, the amount of hours, by simplifying:

534 = 89x

x= 6

The broker charged $100.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total shares = 1000

Price for each shares= $5.

So, the total price of 1000 shares= $5000

If broker is charging a flat percentage of 2% for a trade.

Then, the broker charged for 1000 trade

= 5000 x 0.02

= $100.

Answer:

42 rotten tomatoes would likely be found in 14 boxes.

Step-by-step explanation:

Since [tex]\frac{12}{4} = \frac{3}{1}[/tex] , there are 3 rotten tomatoes in every box.

[tex]\frac{3 * 14}{1 * 14} = \frac{42}{14}[/tex]

3 * 14 = 42, so 14 boxes contain 42 rotten tomatoes.

The equation of the line which passes through (4, 1) in slope - intercept form is y = 1/2x - 1

The equation of a line takes the form:

y = Slope (x) + y - intercept

The slope is already given as 1 / 2 and we have a point on the line. This point can be substituted into the equation of a line to find the value of the y - intercept.

y = Slope (x) + y - intercept

1 = 1/2 (4) + y - intercept

y - intercept = 1 - 2

y - intercept  = - 1

The equation of the line will then be:

y = 1/2x - 1

This is not a prime factorization.

The correct prime factorization is [tex]2^5*3*5^4*11^2[/tex]

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

Further Explanation:

The expression your teacher gave you is not a prime factorization because the 8 isn't prime.

8 = 2*2*2 = [tex]2^3[/tex]

If we replace 8 with [tex]2^3[/tex], then we go from

[tex]2^2*3*5^4*8*11^2[/tex]

to

[tex]2^2*3*5^4*2^3*11^2[/tex]

and that rearranges to

[tex]2^2*2^3*3*5^4*11^2[/tex]

Then we can simplify the [tex]2^2*2^3[/tex] portion to get [tex]2^5[/tex] since we add the exponents while keeping the base '2' the same.

We therefore end up with

[tex]2^5*3*5^4*11^2[/tex]

as the correct prime factorization. Each base (2,3,5,11) is a prime number.

The ratio of the volume of the cylinder to the volume of the sphere = 3:1

Let take the volume of a closed cylinder as V1.

And take the volume of a closed sphere as V2.

And the radius of the cylinder = radius of the sphere = r

Height of the cylinder = h

If height of the cylinder is four times the radius of the cylinder  which means h = 4r

Volume of the closed cylinder V1 = π × r^2 × h

if h = 4r

Then V1 = π × r × r × 4r

V1= 4π × r^3

Volume of the closed cylinder V1= 4π × r^3

Volume oh the sphere V2 = 4/3 × π × r^3

The ratio of the volume of the cylinder to the volume of the sphere

= V1 / V2 = V1 : V2

V1 : V2 = (4π × r^3) ÷ (4/3 × π × r^3)

V1 : V2 = 4 ÷ 4/3 = 4/1 × 3/4 = 3/1 = 3 : 1

The ratio of the volume of the cylinder to the volume of the sphere = 3:1

The transformation is applied to ΔABC to get the ΔA'B'C' is vertical translation of 6 units downwards.

The triangle has the vertices  A(-2, 3), B(2, 1), and C(1, 0)

They are transformed such that:

A(-2, 3)→A'(-2,-3)

B(2, 1)→B'(2,-5)

A(-1, 0)→A'(-2,-6)

Now, if we pay close attention, we can notice that A's y-coordinate is 6 less than A's.

Similar to A, B and C have coordinates that are 6 units lower than the object's coordinates but with the same x-coordinate.

This demonstrates that the graph undergoes a vertical translation; the graph is translated 6 units lower since the new ordinates are 6 units smaller.

A transformation, or f: X→X', is a function that maps to itself. The transformation will result in the pre-image X becoming the image X'. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, may be used in this transformation.

Step-by-step explanation:

Answer:

D: (neg infinity, pos infinity)

R: [-2, pos infinity)

Step-by-step explanation:

Step-by-step explanation:

Formula for distance travelled:

x= ut + 1/2at^2

x is 1.4km, convert this to m since acceleration is in m, = 1400m

u is initial velocity, in this case assume 0

a is acceleration, = 4m/s^2

t is unkown and what we want to find out

Substitute value into formula,

1400 = 0t + 1/2(4)t^2

1400 = 2t^2

t^2 = 1400/2

t^2 = 700

t = 26.458s

Formula for acceleration:

a = (v-u)/t

at= v-u

Substitute value,

4(26.458) = v - 0

v = 105.832 m/s

The resulting equation of isolation and substitution is  9y⁴-466 y² + 5481 = 0

Given:

{x² + y² = 25

{x²/16 - y²/9 = 1

Zach isolated  x² in the first equation, we have:

x² + y² = 25

x² = 25- y²

Zach then substituted the x² into the second equation:

x²/16 - y²/9 = 1                           (put x² = 25- y²)

(25- y²)²/16 - y²/9 = 1                (Expand the bracket)

(625- 50y²+y⁴)/16 - y²/9 = 1      The LCM of 9 and 16 is 144

( 9(625- 50y²+y⁴) - 16 y² ) /144 = 1         Cross multiply

9(625- 50y²+y⁴) - 16 y² = 144

5625 - 450y² + 9y⁴-16 y² = 144

9y⁴-466 y² + 5625 = 144

9y⁴-466 y² + 5625-144 = 0

9y⁴-466 y² + 5481 = 0

Answer:

f(x) = -3x+1

Step-by-step explanation:

every straight graph has an equation f(x) = m * x + b

when the graph goes up when you look at it from left to right, m is a positive number. when it goes down, then m is negative.
the value of m you can read when you go 1 to the right and then count how many you need to go up/down to meet the graph. in this picture, you need to go down 3.
So m = -3
b is how many you habe to go up (+) or down (-) from the center point 0
so in this case you see on the picture that the graph is hitting the y line on 1

so your equation is -3x + 1

The selling price per bag whose purchasing price is $2.57 and profit is 41% should be $4.52

What is selling price?

The amount a buyer pays for a good or service is known as the selling price. Selling price may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.

Given in the question,

Number of bags = 700

Purchase per bag = $2.57

Spoilage = 20%

Profit = 41%

Cost of 700 bags of onion = 700*2.57 = $1799

Spoilage of 20% = 700*20% = 140 bags, which means only 560 bags left to sell

Desired profit = 41 percent

Assume Selling Price be SP

Profit percentage = (560*SP - 1799)/1799

0.41 = (560*SP - 1799)/1799

SP = $4.52

Therefore, selling price is $4.53

Kyle's systolic pressure is 1.75 standard deviations higher than the male average for systolic pressure Kyle's blood pressure : 149.5

What is blood pressure?
Blood pressure (BP) is the force exerted by moving blood against blood vessel walls. The heart's action of pumping blood through the blood vessels is largely responsible for this pressure. The pressure in the major arteries is meant when the term "blood pressure" is used without qualification. Systolic pressure, or the highest pressure during one heartbeat, is typically expressed as the ratio of diastolic pressure, or the lowest pressure between two heartbeats, in blood pressure measurements. It is expressed as a millimetre of mercury (mmHg) above the atmospheric pressure in the immediate vicinity.

The z-score of a measure X in a set with mean and standard deviation is given by:

Z = (X - μ) / σ

The Z-score calculates the deviation of the measure from the mean in standard deviations. We look at the z-score table after determining the Z-score to determine the p-value connected to it. The likelihood that the measure's value is less than X, or the percentile of X, is represented by this p-value. The likelihood that the value of the measure exceeds X is calculated by deducting 1 from the p-value.

This issue involves that:
μ = 125
σ = 14
The z-score for Kyle's systolic blood pressure is 1.75, according to his physician.
He therefore has a 1.75 standard deviations higher systolic blood pressure than the mean.

Which of the following best describes how this standardized score should be interpreted?

Kyle's systolic pressure is 1.75 standard deviations higher than the male average for systolic pressure.

Calculate Kyle's blood pressure in part (b). (Enter a precise quantity as a decimal, fraction, or integer.)
If Z = 1.75, then this is X.

Z = (X - μ) / σ

1.75 = (X - 125) /  14

1.75 x 14 = (X - 125)

24.5 = X - 125

X = 24.5 + 125

X = 149.5

Hence, a) Kyle's systolic pressure is 1.75 standard deviations higher than the male average for systolic pressure.

b) Kyle's blood pressure is 149.5
