Answer:

w=12

Step-by-step explanation:

w+5-9=8

w-4=8

w=12

Answer:

w = 12

Step-by-step explanation:

Subtract the numbers.

5 + w - 9 = 8

-4 + w = 8

Rearrange terms

-4 + w = 8

w - 4 = 8

Add 4 to both sides

w - 4 = 8

w - 4 + 4 = 8 + 4

Add

w - 4 + 4 = 8 + 4

w = 8 + 4

Add

w = 8 + 4

w = 12

Jonah runs 2 (19/20) laps more than the remaining two days

The fractions that have the same denominator are like fractions, to add like fractions directly, But if the denominators are not the same then we need to change their denominators to the same then we can add the fractions.  

To make denominators as same we need to take the LCM of denominators of two fractions.  

Here we have

Jonah ran 1(3)/(4) laps on Monday

=> 1 3/4 = 7/4 laps

On Tuesday he ran 2(3)/(10) laps

=> 2 3/10 = 23/10 laps

On Wednesday he ran 6(1)/(5) laps

=> 6 1/5 = 31/5 laps

The total number of laps ran combining Monday and Tuesday

= 7/4 laps + 23/10 laps  

= (35 + 46)/20         [ take Lcm of 4, 10 i.e 20 ]  

= 81/20

From the above calculations,

Jonah ran 81/20 laps on combining Monday and Tuesdays

The difference between Wednesday's counted laps and Monday, and Tuesday's counted laps

= 31/5 - 81/20

= (140 - 81)/20             [ Take Lcm of 5, 20 i.e 20 ]    

= 59/20            

= 2 (19/20)

Therefore,

Jonah runs 2 (19/20) laps more than the remaining two days

a)  The constant of proportionality of the given problem is; 4

b) An equation that represents the relationship is; y = 4x

c) The graph is as attached.

d) The gallons of water that are needed for 10 scoops of drink mix is; 2.5 gallons

The general equation for the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope of line which tells us the unit rate of change of y with respect to x

c is the y - intercept

Now, it is pertinent to note that y = mx also represents direct proportionality. Making m the subject gives;

m = y/x

Thus, with proportion, we can say;

y₁/x₁ = y₂/x₂

The proportional relationship will be written as;

y = kx

where k is constant of proportionality

From the question, we can say that;

2 scoops require 0.5 gallon of water

6 scoops require 1.5 gallon of water

a) Thus;

k = 2/0.5

k = 2/(1/2)

k = 2 * 2 = 4

b) Equation that represents the relationship can be written as;

y = 4x + c

Since 2 scoops require 0.5 gallon of water, then;

2 = (4 * 1/2) + c

2 = 2 + c

c = 0

The equation will be; y = 4x.

c) Graph of y = 4x is attached at the end.

d) For 10 scoops of water;

10 = 4x

x = 2.5 gallons of water required.

Answer:

This is a function

Step-by-step explanation:

For every input there is only one output.

Answer:

1.7

Step-by-step explanation:

"Increasing" means the y-values are increasing as x-values increase.  Or visually, if you were walking along the graph, from left-to-right, where would you be walking uphill?

The uphill portion is from (-infty, -4).  Once you get to an x-value of -4, then it levels off (so it's "constant") until you get to x = 1, when it goes downhill (the function is decreasing).  

The interval of the domain in which the function is increasing is(-∞, -4). so option C is correct.

A function that is composed of several smaller functions, each with a distinct domain, is said to be piecewise. The term "piecewise" refers to the way in which these sub-functions are defined in terms of various intervals or "pieces" of the function's overall domain.

Given that,

The piecewise function which is discontinuous  at x =1

In the interval  

(-∞, -4)  the value of the function is increasing.

[-4, 1) the value of the function is constant.

(1, ∞)  the value of the function is decreasing.

Hence, the function is increasing in the domain (-∞, -4)

Hello,

I hope you and your family are doing well!

To find the length of each side of the triangle, we can use the formula for the perimeter of a rectangle: perimeter = 2 * (width + length). In this case, the perimeter of the rectangle is 2 * (5cm + 16cm) = 42 cm. Since each side of the triangle has the same length, and the perimeter of the triangle is equal to the perimeter of the rectangle, the length of each side of the triangle is 42cm / 3 = 14 cm.

Therefore, the length of each side of the triangle is 14 cm.

Option C, If your row reduces the matrix A and obtains a row of all zeros except for a single 1 in the rightmost column, then the set {u, v, w} is linearly dependent.

This is because the row of all zeros except for a 1 in the rightmost column indicates that one of the vectors in the set can be expressed as a linear combination of the other vectors.

On the other hand, if your row reduces the matrix A and does not obtain a row of all zeros except for a single 1 in the rightmost column, then the set {u, v, w} is linearly independent. This is because the absence of such a row indicates that none of the vectors in the set can be expressed as a linear combination of the other vectors.

If you are unable to row reduce the matrix A for any reason, then it is not possible to determine if the set {u, v, w} is linearly independent or not.

the values of r, x, and y are related to the sine, cosine, and tangent of angle ø as:

sin ø = y / r

cos ø = x / r

tan ø = y / x

What is trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

In a right triangle, the sides are typically labeled as follows:

The side opposite the angle ø is called the "opposite side" and is labeled "y".

The side adjacent to angle ø is called the "adjacent side" and is labeled "x".

The hypotenuse is the side opposite the right angle and is labeled "r".

The values of r, x, and y can be used to calculate the sine, cosine, and tangent of angle ø. These trigonometric functions are defined as follows:

Sine (sin ø): sin ø = y / r

Cosine (cos ø): cos ø = x / r

Tangent (tan ø): tan ø = y / x

Hence, the values of r, x, and y are related to the sine, cosine, and tangent of angle ø through the above equations.

Step-by-step explanation:

The triangles are congruent by SAS.

The theoretical probability of rolling a two with one standard die in three equivalent form is 1/6, 0.167 and 16.7%

From the question, we have the following parameters that can be used in our computation:

The rolling of a standard die

In this case, we assume that the standard die is a fair die

i.e. the faces have  equal chance of appearing

This means that the sample space of the die is

Sample space = {1. 2. 3. 4. 5. 6}

In this sample space, we have

Number of occurrence of 2 = 1

Number of items in the sample space = 6

The theoretical probability of 2 is then calculated as

Probability = Number of occurrence of 2/Number of items in the sample space

Substitute the known values in the above equation, so, we have the following representation

Probability = 1/6 --- in fraction

Evaluate the quotient

Probability = 0.167 -- in decimal

Express as percentage

Probability = 16.7%

Hence, the probability is 16.7%

The required number of hours  does it take for the size of the sample to double is 11 hours.

Percentages are basically divisions where the denominator is 100. To show that a number is a percent, we utilize the percent image (%) close to the number. For instance, in the event that you got 75 inquiries right out of 100 on a test (75/100), you would have scored 75%.

Let initial population be x.

As question says number of bacteria increases by 9.6% per hours.

9.6% of x takes 1 hours,

A line parallel to one side of a triangle divides the other two sides proportionally.

What is triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Let ΔADE and ΔABC are two triangles.

Given: DE∥BC

To prove:  DB/AD = EC/AE

ΔADE and ΔAC share ∠A

∠A ≅∠A  reflexive property

DE∥BC is given

∠ADE ≅ ∠B   because they are corresponding angles when transversal

            AB cuts parallel lines DE and BC  

ΔADE ∽ ΔABC  a pair of angles in each are congruent.

AB / AD = AC / AE

because corresponding sides of similar triangle's are proportional.

Now subtract 1 from each side

AB / AD - 1 = AC / AE - 1

Combining fractions,

(AB - AD) / AD = (AC - AE) / AE

⇒ DB / AD = EC / AE

Hence, a line parallel to one side of a triangle divides the other two sides proportionally.

The discount price of the shirt will be $15.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

From the information, the store offers a 25% discount and the regular price of a t-shirt is $20. Therefore, based on the information illustrated, the main points to note will be:

Discount = 25%

Regular price = $20.

In this case, the discount price will be the difference between the regular price and the discount.

The discount price will be:

= Regular price - Discount

= $20 - ($20 × 25%)
