Answers

Answer:

The price is $249

Step-by-step explanation:

In order to find the price from taxes, you have to multiply the % so that it equals 100%, then you multiply the tax you paid by that number. For example, since 20 x 5% is 100%, you multiply $12.45 x 20, which equals $249.

The figure below shows the movement of a pedestrian from point B to point E. Using the graph, answer

Answers

Answer: Wheref(the) is the distance in kilometers and the input the is the time in hours

BC f(t) = -5t + 40

CD f(t) = 20. Or f(t)= -20(t/t)+40 OR f(t) = 0t + 20

DE f(t) = -5(t-2) + 40

Step-by-step explanation:

The negative slope means that the distance is decreasing by 5 km/hr when there is movement. Between hours of 4 and 5, the slope is 0, but the distance remains constant at 20. All the options for CD are strange. But they describe the line segment in the graph.

Plug in the values of the hours to check.

Answer:

the diagonal of any rectangular prism is always longer than any one side because the diagonal is the hypotenuse

The triangle is a right triangle because the square of the longest side equals the sum of the squares of the shorter sides.

What is the right triangle?

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.

here, we have,

A triangle with side lengths 7, 80, and 31 is given.

We need to find that the triangle is right-angled.

By Pythagoras theorem,

(Hyp)² = (Opp)² + (Adj)²

(Hyp)² = (80)² = 6400

(Opp)² + (Adj)² = 7² + 31²

= 49 + 961

= 1,010

Therefore, (Hyp)² > (Opp)² + (Adj)²

Yes, the triangle is a right triangle because the square of the longest side equals the sum of the squares of the shorter sides.

Write the equation of the line that goes through the point (3, 7) and has a slope of 2 in point-slope form.



Remember that point-slope form is `y\ -\ y_{1}\ =\ m\left(x\ -\ x_{1}\right)`



Once you have your equation, graph its line on the coordinate plane to the left.

Write the equation of the line that goes through the point (3, 7) and has a slope of 2 in point-slope

Answers

Answer:

Step-by-step explanation:

All we need to do here is to employ the point-slope formula for the equation of a straight line:  y - k = m(x - h).  Here h = 3, k = 7 and m = 2.  After substituting these values into y - k = m(x - h), we get:

y - 7 = 2(x - 3)  (point-slope form)

This is perfectly adequate/correct, but it can be simplified into slope-intercept form y = mx + b:

y = 2x - 14 + 21, or

y = 2x + 7       Clearly, the y-intercept is 7 and the slope is 2.  This is the slope-intercept form.

To graph this line, let x = 0.  Then the y-intercept is (0, 2).  Plot this.  Next, find the x-intercept:  Let y = 0 and solve the resulting equation for x:

0 = 2x + 7, or 2x = -7, or x = -7/2.  Plot this (-7/2, 0).  Finally, draw a line through these two points (0, 2) and  (-7/2, 0).

Point-slope form
y-7=2(x-3)
Slope intercept
y-7=2(x-3)
y-7=2x-6
y=2x-6+7
y=2x+1

Where y-intercept is 1 ,slope is 2. Start from y 1 on the graph count 2 rise and 1 run.

What is a set theory?

The area of mathematical logic known as set theory examines sets, which are essentially collections of objects. Set theory is an area of mathematics that primarily deals with objects that are pertinent to mathematics as a whole, despite the fact that any form of an object can be gathered into a set.

Given that the universal set is U = {1, 2, 3, 4, 5}, and the set A is {1,5}. The value of the set A' will be calculated as,

U = {1, 2, 3, 4, 5

A =  {1,5}

A' = {2,3,4}

Therefore, the value of the set A' for the set A{1,5} from the universal set will be A'{2,3,4}.

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.​

Answers

To solve this problem, let's denote the mass of the dog as D and the mass of the lion as L.

We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:

0.80D = 0.24L

We are also given that the mass of the lion is 105 kg more than the mass of the dog:

L = D + 105

We can use these two equations to find the values of D and L.

Substituting the value of L from the second equation into the first equation:

0.80D = 0.24(D + 105)

Now, let's solve for D:

0.80D = 0.24D + 0.24(105)

0.80D - 0.24D = 25.2

0.56D = 25.2

D = 25.2 / 0.56

D ≈ 45

Now that we have the value of D, we can find the value of L by substituting it back into the second equation:

L = 45 + 105

L = 150

Therefore, the total mass of the dog and the lion is:

D + L = 45 + 150 = 195 kg

So, the total mass of the dog and the lion is 195 kg.

You mix 23.385 grams of sugar and 12.873 grams of baking soda in a glass container for an experiment. You place the container on a scale to find that the total mass is 104.2 grams. What is the mass of the container

Answers

23.385+12.873=36.258
104.2-36.258=67.942
Answer=67.942

The mass of the container is 67.942 grams.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that amount of sugar is 23.385 grams, the amount of soda is 12.873 and the total mass is 104.2 grams.

The weight of the container will be calculated as below:-

Total weight of sugar and sods = 23.385+12.873=36.258

Weight of container = 104.2-36.258=67.942

Weight of container = 67.942 grams

Therefore, the mass of the container is 67.942 grams.
