How would you find the number, 3/7 of which is equal to t? (let's say it was any number, just need the equation)

Answers

Answer 1

Let the number be x
(3/7) x = t
I can't think of anything useful to add to this. How about an example?

Let x = 49

(3/7) x = t
(3/7) * 49 = t seven will go into 49
3 * 49 = t
t = 147

The measure of the side length of the right triangle is 20.

What is the measure of the missing side length?

A tangent makes an angle of 90 degrees with the radius of a circle.

Therefore, the triangle formed is a right triangle.

From the diagram:

Leg 1 = 12

Leg 2 = 16

Hypotenuse =?

To find the hypotenuse, we use the Pythagoras theorem:

(Hypotenuse)² = ( Leg 1 )² + ( Leg 2 )²

(Hypotenuse)² = ( 12 )² + ( 16 )²

(Hypotenuse)² = 144 + 256

(Hypotenuse)² = 400

Take the square roots of both sides:

Hypotenuse = √400

Hypotenuse = 20

Therefore, the side length measures 20 units.

Option C) 20 is the correct answer.

4 times x plus 2/3 equals 16/3.

4x + 2/3= 16/3
subtract 2/3 from both sides

4x= 14/3
divide both sides by 4

x= 14/3 ÷ 4
to divide fractions, multiply by reciprocal/inverse of 4

x= 14/3 * 1/4

Eli, Freda and Geoff were given £800 to share in the ratio of their ages.
Eli is 9 years old,Feda is 13 years old and Geoff is 18 years old.
How much should they each get?
Eli-
Freda-
Geoff-

Answers

First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of Geoff:
[tex]9+13+18=40[/tex]
The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.

Next, we are going to multiply the ratio between the age of the person and their combined age by £800:
For Eli: [tex] \frac{9}{40} *800=180[/tex]
For Freda: [tex] \frac{13}{40} *800=260[/tex]
For Geoff: [tex]\frac{18}{40} *800=360[/tex]

We can conclude that Eli will get £180, Freda will get £260, and Geoff will get £360.

Final answer:

Calculate how £800 should be divided among Eli, Freda, and Geoff based on their ages.

Explanation:

Ratio of ages: 9:13:18 = 9/40 : 13/40 : 18/40

Total amount: £800

Eli: £200

Freda: £290

Geoff: £410

Suppose you have $16,000 to invest in three stocks, A, B, and C. Stock A is a low-risk stock that has expected returns of 4%. Stock B is a medium-risk stock that has expected returns of 5%. Stock C is a high-risk stock that has expected returns of 6%. You want to invest at least $1,000 in each stock. To balance the risks, you decide to invest no more than $7,000 in stock C and to limit the amount invested in C to less than 4 times the amount invested in stock A. You also decide to invest less than twice as much in stock B as in stock A. How much should you invest in each stock to maximize your expected profit? Complete the constraints.

Answers

Answer:

Stock A: 1

Stock B: 1 and y=2

Stock C: 1, 7, 4

Final answer:

To maximize expected profit, you need to determine the amount to invest in stocks A, B, and C while considering the given constraints.

Explanation:

To invest in each stock to maximize expected profit, we need to determine the amount to invest in stocks A, B, and C while considering the given constraints.

Let's denote the amount invested in stock A as x, in stock B as y, and in stock C as z.

The constraints are as follows:

At least $1,000 should be invested in each stock: x > $1,000, y > $1,000, z > $1,000No more than $7,000 should be invested in stock C: z < $7,000The amount invested in C should be less than 4 times the amount invested in A: z < 4xThe amount invested in B should be less than twice the amount invested in A: y < 2x

To maximize expected profit, we need to maximize the sum of the expected returns from each stock:

Expected profit = 0.04x + 0.05y + 0.06z

By solving the constraints and optimizing the expected profit function, we can find the optimal values for x, y, and z.

Answers

VA=W
120(5)=W
600=W
600 Watts

Final answer:

The number of watts for a circuit with 120 volts and 5 amps is 600 watts.

Explanation:

The formula for calculating the power in an electrical circuit is: Power (P) = Voltage (V) × Current (I).

To calculate the number of watts, we can substitute the given values into the formula:
Volts (V) = 120
Amps (I) = 5

Therefore, the number of watts (P) = 120 V × 5 A = 600 W.

Answer:

0.8 and 1.1 are outliers of the given data set.

Step-by-step explanation:

The given data set is

5.8, 6.1, 4.9, 10.9, 0.8, 6.1, 7.4, 10.2, 1.1, 5.2, 5.9

Arrange the data set in ascending order

0.8, 1.1, 4.9, 5.2, 5.8, 5.9, 6.1, 6.1, 7.4, 10.2, 10.9

Divide the data in four equal parts.

(0.8, 1.1), 4.9,( 5.2, 5.8), 5.9,( 6.1, 6.1), 7.4, (10.2, 10.9)

From the above division we get,

[tex]Q_1=4.9[/tex]

[tex]Median=5.9[/tex]

[tex]Q_3=7.4[/tex]

The interquartile range of the data is

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=7.4-4.9=2.5[/tex]

If all the data elements lies in the interval [Q₁-1.5(IQR),Q_3+1.5(IQR)], then the data set has no outliers.

[tex][Q_1-1.5(IQR),Q_3-1.5(IQR)]=[4.9-1.5(2.5),7.4-1.5(2.5)]=[1.15,11.15][/tex]

Since all the elements lie in the interval [1.15,11.15] except 0.8 and 1.1, therefore 0.8 and 1.1 are outliers.

4y + 20 + 3y = 6
7y = 6 - 20

x = 6

The solution is (6,-2)

Part (3):
The equations given are:

Answers

The equation would be y=12000(2)ˣ.

This equation is of the form y=a*bˣ, where a is the initial population and b is the rate that it increases by. In this problem, a = 12000 and b=2, since it doubles each time.

Answer:

[tex]Y = 12,000 \cdot (2)^X[/tex]

Step-by-step explanation:

The exponential function is given by:

[tex]y =a \cdot b^x[/tex]

where,

a is the initial values and b is the growth factor.

As per the statement:

The initial number of bacteria in a culture is 12,000.

⇒Number of bacteria initially(a) = 12,000

It is also given that the culture doubles each day.

⇒ growth factor [tex]b= 2[/tex]

We have to find the exponential function to model the population Y of bacteria after X days.

By definition of exponential function:

[tex]Y = 12,000 \cdot (2)^X[/tex]

where, x represents the days and Y is the population after X days.

Therefore, an exponential function to model the population is,

[tex]Y = 12,000 \cdot (2)^X[/tex]

Which characteristics best describe an obtuse isosceles triangle? I. One angle is greater than 90°. II. All side lengths are equal. III. Two sides meet at a 90° angle. IV. Two sides are equal in length. A. I and IV B. II and III C. I and II D. III and IV

Answers

An obtuse triangle is a triangle that has an angle greater than 90 degrees, so 1. One angle is greater than 90 degrees is correct.

An obtuse isosceles triangle is defined as a three-sides triangle shape that has one angle (out of three angles) more than 90 degrees and whose two sides are always congruent that includes obtuse angle in between. So it will follow :-

⇒ Obtuse means "one angle is greater than 90 degrees".

⇒ Isosceles means "Two sides are equal in length".

So, option A is correct, i.e. statements I and IV.

Find the difference. express your answer in simplest form. (2s/s^2-4s+4) - (4/s^2-4s+4)

Answers

To find the difference, we are going to destroy the parenthesis first, and then, we are going to perform the operations. Remember that to destroy a parenthesis preceded by a negative sign (-), you should change the signs of the factors inside the parenthesis:
[tex] \frac{2s}{s^2-4s+4} -( \frac{4}{s^2-4s+4} )[/tex]
[tex]\frac{2s}{s^2-4s+4} -\frac{4}{s^2-4s+4}= \frac{2s-4}{s^2-4s+4} [/tex]

Now we can factor both numerator and denominator and simplify:
[tex]\frac{2s-4}{s^2-4s+4} = \frac{2(s-2)}{(s-2)^2} = \frac{2}{s-2} [/tex]

We can conclude that the difference in simplest form is: [tex] \frac{2}{s-2} [/tex]

To get started, combine -4s+4 with 4s - 4. Result: 0. That leaves

Answers

5 represents one of the dimensions of the rectangle, either length or width.

Answer: The length is 5 times the width

Step-by-step explanation:

Given: The area of rectangle = [tex]5x^2=(5x)(x)[/tex]

Here x must be a positive real number since it can not be negative.

Also for area of rectangle =[tex]length \times width[/tex]

And length is always greater than width of rectangle, therefore in the given expression 'x' must be width and '5x' must be length of rectangle .

[∵ for every positive x , 5x>x]

Hence, the coefficient 5 means the length is 5 times the width.

we plug in x =3.2 in the equation
