Answer: 45/10

Explanation:

We want to add

11/5 + 23/10

The first step is to find the lowest common multiple, LCM of the denominators. The LCM of 5 and 10 is 10. We would divide the LCM by each denominator and multiply each numerator by the results. The common denominator of the final fraction would be the LCM. We have

For the first fraction,

10/5 = 2

2 x 11 = 22

For the second fraction,

10/10 = 1

1 x 23 = 23

Thus, the final fraction would be

(22 + 23)/10

= 45/10

Answer:

Angle TUV = 46 degrees.

Explanation:

In the diagram, angle TUV is the external angle.

The external angle is always half the difference of the internal angles.

Therefore:

We simplify to obtain our result.

The measure of angle TUV is 46 degrees.

The standard form of the quadratic equation is given as follows:

y = x² - 2x - 15.

A quadratic equation is modeled according to the following rule:

y = ax² + bx + c.

From the given table, when x = -3, y = 0, hence the first equation is given by:

(-3)²a + (-3)b + c = 0

9a - 3b + c = 0.

When x = -1, y = -12, hence the second equation is given by:

-12 = a(-1)² + b(-1) + c

a - b + c = -12.

When x = 1, y = -16, hence the third equation is given by:

-16 = a(1)² + b(1) + c

a + b + c = -16.

Then the system of equations to find the coefficients is given as follows:

Using a calculator, the solution to the system is:

a = 1, b = -2, c = -15.

Hence the equation is given by:

y = x² - 2x - 15.

First, let's get all the values to grams.

1.8 kilograms is equal to 1800 grams.

315 deka grams is equal to 3150 grams.

1350 is already in grams.

So Antoine purchased 1800 grams of apples and 3150 grams of oranges. Adding them up, we have a total of:

Since this: 4950 grams, is 1350 grams more than the wieght of bananas, than, the weight of banas, "b", is:

Answer:

7 cubic feet

Step-by-step explanation:

so first you do length times height in this case it would be 16 times 8

you get 128 now you divide 896 by 128 and you get an answer of 7.

One way to check is you do length times width times height.

So 16 × 7 × 8 =896

Answer: 7 feet cubed

Express the number 0.00005348 in terms of a power of 10

Solution

For this case we just need to count the number of zeros before the first number different from 0 and if we do this we have 5 numbers before 5 so we can write the number like this:

5.348 x10^-5

Solution:

Given:

Using the trig ratio of cot;

The hypotenuse is gotten using the Pythagoras theorem;

Thus, the sketch of the right triangle is;

Hence,

The value of (s) that satisfy the given equation → 1/4+s=18/20 is 0.65.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. There are different types of equation such as - Linear Equations, Radical Equations, Exponential Equations, Rational Equations etc.

Given is the following equation written in variable (s)

1/4 + s = 18/20

We have -

1/4 + s = 18/20

We will solve the given expression using the transpose method -

1/4 + s = 18/20

Shifting (s) to the left hand side and constant numbers to right hand side, and then solving for (s), we get -

s = 18/20 - 1/4

s = 9/10 - 1/4

s = 0.9 - 0.25

s = 0.65

The value of s will be 0.65

Therefore, the value of (s) that satisfy the given equation → 1/4+s=18/20 is 0.65.

Answer:

C.

Step-by-step explanation:

The relationship is proportion if y/x is constant.

So it is C because 12/4 = 15/5 = 18/6 = 3.

Answer:

x=55

Step-by-step explanation:

2x+6+x+9=180

3x=165

x=55

:]

Answer: x=55

Step-by-step explanation:

Since the lines are parallel, the two angles on the line are supplementary angles.

It means they would add to 180.

1) Set up the equation

(2x+6)+(x+9)=180

2) Combine like terms

3x+15 = 180

3) Move the 15 to the other side to leave x

3x = 180 - 15

3x = 165

4) Set x by itself

x = 165/3

x=55

The Dosage in milligrams per​ min, mg/min : 0.01mg / min

The Dosage in milligrams per​ hour, mg/hr : 0.6mg/hr

The dosage available in milliliters per hour, ml/hr: 6ml/hr

What is Dosage ?

A dosage is a predetermined amount of a drug, food, or pathogen that is administered as a single unit. The dose increases with the amount administered. In medicine, doses are most frequently calculated for substances.

Given,

Dose(mcg) = 10mcg/min

Dose available = 50mg

Volume of dose available = 500ml

a) The dosage in milligram per minute will be:

                                    = 10mcg / 1000mcg

                                    = 0.01mg / min

b) The dosage in milligrams per​ hour, mg/hr :

                                    = 10mcg x 60min / 1000mcg

                                    = 0.6mg/hr

c) By dosage formula we can write:

                                    = OxV / A

Where,

O = Dose ordered

V = Volume of dose available

A = Dose available

So that we know,

Dose ordered (mg) = 0.6 mg

Volume of dose available (mL) = 500 mL

Dose available (mg) = 50 mg

                                                  = 0.6 x 500 / 50

                                                  = 6ml/hr

Hence,

The Dosage in milligrams per​ min, mg/min : 0.01mg / min

The dosage in milligrams per​ hour, mg/hr : 0.6mg/hr

The dosage available in milliliters per hour, ml/hr: 6ml/hr

A function is called being one-to-one if, for every value of x, there is only one value of y and vice-versa.

If the graph of the function is given, a practical rule to determine if the function is one-to-one is to use the horizontal-line test.

This test is as follows: Imagine you have a horizontal line (maybe a ruler) and you can move it up and down the grid.

If your line touches the graph only once at every vertical position, then your function is one-to-one.

Now if we test our function drawn in blue, we can touch it only once as we move our line up and down, thus:

The line which is parallel to X-axis or which is drawn horizontally in the cartesian plane has its slope equal to zero.

As per the question statement, we are supposed to tell the significance of a zero sloped line. Before solving it, we need to know the formula for calculating the slope i.e., m = tanθ, where θ is the inclination angle of the line wrt X-axis.

Slope zero means m = 0 i.e., tanθ = 0 i.e., θ = 0 degrees

Hence a line having NO inclination or in simple words, is parallel to X-axis is known as a zero sloped line.

The lifetime in hours of an electronic tube will be of 2 hours.

A probability density function, also known as the density of a continuous random variable, is a function used in probability theory whose value at any given sample (or point) in the sample space can be interpreted as giving a relative likelihood that the random variable's value would be close to that sample. While the absolute likelihood of a continuous random variable taking on any given value is 0, probability density (PDF) at two different samples can be used to infer, in any given draw of the random variable, how much more likely it would be that the random variable would be close to one sample compared to the other sample.

We have,

f(x) = xe^(-x)             x>0
