what is the same value as 8.76

Answer:

34

Step-by-step explanation:

When estimating the product of an integer and a decimal, first round the decimal to its nearest whole number.

Therefore,

So an estimate of the product is:

[tex]\implies 17 \times 1.68 \approx 17 \times 2[/tex]

Partition 17 into tens and units:

[tex]\implies17 \times 2= (10+7) \times 2[/tex]

Apply the distributive property of multiplication over addition:

[tex]\begin{aligned}\implies (10+7) \times 2&=(10 \times 2)+(7 \times 2)\\&=20+14\\&=34\end{aligned}[/tex]

Therefore:

[tex]\boxed{17 \times 1.68 \approx 34}[/tex]

Answer:

≈ 34

Step-by-step explanation:

The estimate value of 1.68,

→ 17 ≈ 17

→ 1.68 ≈ 2

Then the estimated product is,

→ 17 × 1.68

→ 17 × 2 = 34

Therefore, the product is 34.

The probability that they two people are chosen and travel by different transport is 47/144

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Probability is given as sample space / total outcome

Probability to travel by car p(C)= 5/12

Probability to travel by bus P(B)= 4/12=1/3

Probability to travel by train P(T)= 3/12= 1/4

for two people chosen at random

P(C ×B)= 5/12×1/3= 5/36

P(B×T)= 1/3×1/4= 1/12

P(C×T)= 1/4×5/12= 5/48

Therefore the probability that the two chosen travel by different car is

P(C ×B)+P(B×T)+P(C×T)= 5/36+1/12+5/48

= 141/432

divide through by 3

= 47/144

Hence the get the required answer.

Answer:

The two points used to find the slope:

[tex]x_1,y_1[/tex]: 2,30

[tex]y_1,y_2:[/tex] 4,10

Final equation: y = -10x + 50

Step-by-step explanation:

From a fellow 8th grader <3

First, let's review the slope of a line: y = mx + b

Where m is the slope, and b the y-intercept

Let's find the slope. To do this I will select 2 points from this graph, and using the slope formula I will calculate it

Slope formula: [tex]\frac{rise}{run} =\frac{change- in- y}{change-in-x} =\frac{y^2-y^1}{x^2-x^1}[/tex]

To get the most accurate answer, I will be using the 2 points given that are directly on the line:

1 = (2, 30)

2 = (4, 10)

Slope: [tex]\frac{10-30}{4-2} =\frac{-20}{2} =-10[/tex]

m = -10

It makes sense that it is a negative, since the graph continues downwards.

Let's update our equation: y = -10x + b

We can see that the line intersects the y-axis at y = 50

Plug this into our b-value:

y = -10x + 50

Now, I would recommend using a graphing calculator (like a TI-83) or an online one (like desmos) to double check this. I have attached a screenshot of this line on desmos. From there we can see if this line matches up with the one seen on your graph.

Our answer is:

The two points used to find the slope:

[tex]x_1,y_1[/tex]: 2,30

[tex]y_1,y_2:[/tex] 4,10

Final equation: y = -10x + 50

Please let me know if this helped you, and if this was the correct answer! If it is incorrect I will do my best to revise my answer.

Answer: y intercept is (0,50) and Slope is -10.

Final equation is y= -10x+50

Step-by-step explanation:

Y-intercept is at what point the line intercepts the y-axis. It intersects at (0,50) coordinate point as you can see.

Slope is change in y divided by the change in x. When you change x by 1, y changes by -10. So it is -10/1 = -10. Slope is -10.

Since we know y intercept and slope equation is y=-10x+50

The true statements are:

The center of the circle lies on the x-axis

The radius of the circle is 3 units.

The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

The standard equation of a circle is expressed as:

x²+y²+2gx+2fy+C=0

Centre is (-g, -f)

radius = √g²+f²-C

Given a circle whose equation is

x²+y²-2x-8=0

Get the centre of the circle

2gx = -2x

2g = -2

g = -1

Similarly, 2fy = 0

f = 0

Centre = (-(-1), 0) = (1, 0)

This shows that the center of the circle lies on the x-axis

r = radius = √g²+f²-C

radius = √1²+0²-(-8)

radius =√9 = 3 units

The radius of the circle is 3 units.

For the circle x² + y² = 9, the radius is expressed as:

r² = 9

r = 3 units

Hence the radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

The value of x in the given triangle is x = 4

From the question, we are to determine the value of x.

From the given triangle,

We can write that

(9x+ 1)° + 78° + (17x - 3)° = 180° (Sum of angles in a triangle)

Now, we will solve for x

(9x+ 1)° + 78° + (17x - 3)° = 180°

9x° + 1° + 78° + 17x° - 3° = 180°

Collect like terms

9x° + 17x° = 180° - 1° + 3° - 78°

26x° = 104°

x = 104/26

x = 4

The probability that first card selected has a yellow bird and second card selected has a lion both with and without replacement is 1/40 and 1/38. respectively.

Probability is the likelihood of an event or more than one event occurring. It is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.

Probability may also be described as the likelihood of an event occurring divided by the number of expected outcomes of the event. i.e.,

               P(A) = f / N

Where:

P(A) = Probability of an event (event A) occurring

f = Number of ways an event can occur (frequency)

N = Total number of outcomes possible

Here deck of 20 cards are given which implies total number of possible outcomes are 20. From these 20 cards 5 cards has lions and 5 cards has birds in which 2 are yellow and 3 are red.

Now two cards are selected randomly.

We have to find the probability that first card selected has a yellow bird and second card selected has a lion both probability that first card selected has a yellow bird and second card selected has a lion both with and without replacement.

Probability with replacement:

Probability that first card selected has a yellow bird = 2/20  ---(1)

Since replacement is allowed so the probability that second card selected has a lion = 5/20---(2)

So, the probability that first card selected has a yellow bird and second card selected has a lion with replacement = (1) * (2) = 2/20 * 5/20 = 1/40.

Probability without replacement:

Probability that first card selected has a yellow bird = 2/20  ---(3)

And since replacement is not allowed, the probability that second card selected has a lion = 5/19---(4)

So, the probability that first card selected has a yellow bird and second card selected has a lion without replacement = (3) * (4) = 2/20 * 5/19 = 1/38.

Therefore, the probability with and without replacement is 1/40 and 1/38. respectively.

Using an exponential decay equation, we will see that after 11 hours the element will decay to 299 grams.

We know that we have an element with a half-life T, and it has a decay equation that can be written as:

f(t) = A*e^(-t*ln(2)/T)

Where A is the initial amount of the element, and f(t) is the amount of the element t hours after.

In this case the given values are:

A = 500g

T = 15h

Then the exponential decay is:

f(t) = 500g*e^(-t*ln(2)/15h)

And we want to find the value of t such that f(t) = 299g, then we can solve:

299g =  500g*e^(-t*ln(2)/15h)

299/500 = e^(-t*ln(2)/15h)

If we apply the natural logarithm in both sides we get:

ln(299/500) = -t*ln(2)/15h

-ln(299/500)*15h/ln(2) = t

11 h = t

It will take 11 hours to go from 500 grams to 299 grams.

Check the picture below.

The transformation that is applied to the ΔABC to get the ΔA'B'C' is vertical translation by 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 carefully observe we can see that the y-coordinate of A' is 6 less than that of A.

Similarly for B and C the coordinates are 6 units less than that of the object, but the x-coordinate remains the same.

This proves that the graph follows a vertical transformation and since the new ordinates are 6 units smaller, so the graph is translated 6 units downwards.

A function, f, that maps to itself is known as a transformation, or f: X→X'. The pre-image X will change into the picture X' following the transformation. This transformation can use any operation, or a combination of operations, including translation, rotation, reflection, and dilation.
