Answer:

B

Step-by-step explanation:

under a dilatation about the origin of scale factor 3

since dilatation is about the origin multiply the coordinates of A, B and C by 3

A(8, 15) → A' (24, 45)

B(12, 13) → B'(36, 39)

C(8, 10) → C'(24, 30)

using the distance formula

with (x₁, y₁ ) = C'(24, 30) and (x₂, y₂ ) = B'(36, 39)

BC = [tex]\sqrt{(36-24)^2+(39-30)^2}[/tex]

     = [tex]\sqrt{144+81}[/tex] = [tex]\sqrt{225}[/tex] = 15 → B

Step-by-step explanation:

Below are the 3 major determining factors to determine a good credit score:-

1) Payment history - The payment history comprises of 35 percent of the total credit score and is the most important factor in calculating credit scores. An easiest way for borrowers to improve their credit score is by making quick timely payments.

2) Credit utilization - It is the percentage of available credit which has been borrowed. It makes up 30 percent of the total credit scores.

3) Long-standing lines of credit - the amount of time each account has been open.It makes up 15 percent of the total credit score. In order to improve the credit scores, people without a credit history must begin using credit, and those having credit must maintain long-standing accounts.

The -30 does not matter in this case because it does not affect the slope. So, you can ignore it and simplify the question to 5x-7y=0.

Move the -7y to the right to get 5x=7y. Then, divide by 7 to isolate y to get y=5x/7.

Therefore, the slope is 5/7.  

Final answer:

The slope of the graph of the line 5x - 7y = -30 is 5/7, determined by rewriting the equation in the slope-intercept form and identifying the coefficient of the x term as the slope.

Explanation:

To find the slope of the graph of the line given by the equation 5x - 7y = -30, we need to rewrite the equation in the slope-intercept form, which is y = mx + b, where m is the slope, and b is the y-intercept. Starting with the given equation:

5x - 7y = -30

-7y = -5x - 30

y = (5/7)x + 30/7

From the transformed equation y = (5/7)x + 30/7, we can see that the slope (m) is 5/7. This means that for every one-unit increase in the independent (x) variable, the dependent (y) variable increases by 5/7 units.

Answer:

A. [tex]\dfrac{3}{8}[/tex] is smaller than [tex]\dfrac{1}{2}[/tex].

Step-by-step explanation:

The given fraction is [tex]\dfrac{1}{2}[/tex].

To compare two fractions, either numerator or denominator should be equal.

It is required to compare the given fraction with [tex]\dfrac{3}{8}[/tex] and [tex]\dfrac{5}{8}[/tex].

Now, the given fraction can be written as,

[tex]\dfrac{1}{2}\times\dfrac{4}{4}=\dfrac{4}{8}[/tex]

Now, the denominator of the given fraction is equal to that of other fractions.

In the fraction [tex]\dfrac{3}{8}[/tex] , numerator 3 is smaller than that of the given fraction which is 4.

So, the fraction [tex]\dfrac{3}{8}[/tex]  is smaller than [tex]\dfrac{1}{2}[/tex].

In the fraction [tex]\dfrac{5}{8}[/tex] , numerator 4 is larger than that of the given fraction which is 4.

So, the fraction  [tex]\dfrac{5}{8}[/tex] is larger than [tex]\dfrac{1}{2}[/tex].

Answer: A formula that can be used to find the answer is (x Squared = 110.25) So (x times x = 110.25) 10.5 is the length of one side because 10.5 squared = 110.25.

Answer is 10.5

Final answer:

To find the length of one side of Mickey’s square-shaped office with an area of 110.25 square feet, we take the square root of the area, resulting in a side length of 10.5 feet.

Explanation:

The question asks for the length of one side of Mickey’s square-shaped office given that the area of the office is 110.25 square feet. To find the length of one side, we can use the formula for the area of a square, which is area = side², where ‘side’ represents the length of one side of the square. Given that the area = 110.25 ft², we solve for the side length by taking the square root of the area.

So, the calculation would be side = √(110.25 ft²), which equals 10.5 feet. Therefore, the length of one side of Mickey’s square office is 10.5 feet.

Answer,

X = 3/4

Explanation,

Step 1: Simplify both sides of the equation.

3.25 + 0.5x + (1)(1)/3 + 5/6x = (5)(11)/12

3.25 + 0.5x + 1/3 + 5/6x = 55/12

(0.5x + 5/6x) + (3.25 + 1/3) = 55/12 (Combine Like Terms)

4/3x + 3.583333 = 55/12

4/3x + 3.583333 = 55/12

Step 2: Subtract 3.583333 from both sides.

4/3x + 3.583333 − 3.583333 = 55/12 − 3.583333

4/3x = 1

Step 3: Multiply both sides by 3/4.

(3/4) * (4/3x) = (3/4) * (1)

x = 3/4

Answer:

$300

Step-by-step explanation:

Let Dave's saving be D and Sam's savings be S

[tex]\frac{D}{S}=\frac{5}{4}\\4D=5S\\\frac{4}{5}D=S[/tex]

So we subtract 40 from each of them and then the ratio becomes 13 is to 10. Hence we can write:

[tex]\frac{D-40}{S-40}=\frac{13}{10}\\10(D-40)=13(S-40)\\10D-400=13S-520\\-400+520=13S-10D\\120=13S-10D[/tex]

Plugging in [tex]\frac{4}{5}D[/tex] into S (as we found earlier), we can solve for D (our answer):

[tex]120=13S-10D\\120=13(\frac{4}{5}D)-10D\\120=\frac{52}{5}D-10D\\120=\frac{2}{5}D\\D=\frac{120}{\frac{2}{5}}=120*\frac{5}{2}=300[/tex]

So, Dave's savings at first, D, is $300.

Answer:

Approximately  1.9 seconds   (correct to nearest tenth)

Step-by-step explanation:

Looks like the function is  d = -16t^2 + 55    ( you left out the t)

The answer is the value of t when d = 0 so we have the equation:-

0 =  -16t^2 + 55

16t^2 = 55

t^2 = 55/16

t = sqrt (55/16)

= 1.85 seconds

Answer:

t is approximately 1.854049622 seconds

Step-by-step explanation:

d = -16 t^2 + 55

Let d = 0

0 = -16 t^2 + 55

Subtract 55 from each side

-55 = -16 t^2

Divide by -16 on each side

-55/-16 =  -16 /-16t^2

55/16 = t^2

Take the square root of each side

sqrt(55/16) = sqrt(t^2)

We only take the positive square root because time must be positive

sqrt(55/16) = t

t is approximately 1.854049622 seconds

Given: Scale factor, [tex]k = \frac{1}{4}[/tex] and centered at (5, -5).

Labelled the given figure as A, B and C.

The coordinates of the given triangle ABC are;

A = (-3, 7)

B = (-7, -5) and

C = (9, 3)

To find the image of the figure after a dilation with scale factor 1/4 centered at (5, -5).

The rule of dilation with scale factor 1/4 and centered at (5, -5) is given by;

[tex](x, y) \rightarrow (\frac{1}{4} (x -5) +5 , \frac{1}{4}(y+5) -5)[/tex]

or

[tex](x, y) \rightarrow (\frac{1}{4}x + \frac{15}{4}, \frac{1}{4}y -\frac{15}{4})[/tex]

The coordinates of the image of the figure after dilation are;

[tex]A(-3, 7) \rightarrow (\frac{1}{4}(-3) + \frac{15}{4}, \frac{1}{4}(7)-\frac{15}{4})=(\frac{-3}{4}+ \frac{15}{4}, \frac{7}{4}- \frac{15}{4}) = (\frac{-3+15}{4}, \frac{7-15}{4}) = (\frac{12}{4}, \frac{-8}{4}) = A'(3, -2)[/tex]

[tex]B(-7, -5) \rightarrow (\frac{1}{4}(-7) + \frac{15}{4}, \frac{1}{4}(-5)-\frac{15}{4})=(-\frac{7}{4}+ \frac{15}{4}, -\frac{5}{4}- \frac{15}{4}) = (\frac{-7+15}{4}, \frac{-5-15}{4}) = (\frac{8}{4}, \frac{-20}{4}) = B'(2, -5)[/tex]

[tex]C(9, 3) \rightarrow (\frac{1}{4}(9) + \frac{15}{4}, \frac{1}{4}(3)-\frac{15}{4})=(\frac{9}{4}+ \frac{15}{4}, \frac{3}{4}- \frac{15}{4}) = (\frac{9+15}{4}, \frac{3-15}{4}) = (\frac{24}{4}, \frac{-12}{4}) = C'(6, -3)[/tex]

Answer:

Step-by-step explanation:

If there are 4 coins and two faces on those coins then that means there are 4 faces flipping them both at the same time means it will have a 25% chance of them landing on the same side

Answer:

25%

Step-by-step explanation:

Okay so let's just say that you are tossing one coin and you want to know the chance of it landing as tails well its a 50 out of 100 chance of it being tails that is because there are two sides. But you have two so all together there are 4 sides. So let's say that each coin is 50 so now we need to find a even number for all sides, So let's just do 50 -25 = 25 so that lets us know that we can make each side 25%... So now you have a 25%  chance of landing both coins as a tail.

I'm so sorry if this does not make seance I have a very hard time explaining things...  

Answer:

-35%  

Step-by-step explanation:

To solve this equation, the first thing we have to do is to convert percentages to decimals because we are doing mathematical operations with a fraction.

To convert a percentage to a decimal, we just divide by 100. So, 60% equals 0.60, and 25% equals 0.25.

Next, we subtract these values from 1/2.

So, we have the following steps:

1. Calculate 1/2 - 0.60 (which is the decimal equivalent of 60%). This gives us -0.10.

2. Then subtract 0.25 (which is the decimal equivalent of 25%) from the result. So, -0.10 - 0.25 equals -0.35.

Therefore, 1/2 - 60% - 25% equals -0.35.

The total number of seats in a row = 5

Lets suppose you are standing in front of the row, so you have 3 seats on one side of you then the passage of the plane and 2 seats on the other side. Out of 3 seats, 1 is window, 1 is middle and 1 is aisle. Similarly, out of the 2 seats on the other side, 1 is the window and 1 is aisle seat, Hence, a total of 5 seats.

As 2 friends have requested to be seated in the same row. So probability of them getting aisle seats becomes 2/5 for 1st friend (as there are 2 aisle seats out of 5 seats) and 1/4 (1 seat is already allocated to the friend so only 1 aisle seat is left out of 4 seats) for the second one.

So, joint probability becomes = [tex]\frac{2}{5}*\frac{1}{4}= \frac{1}{10}[/tex]

Answer:

-11/-16

Step-by-step explanation:

M= Y2 - Y1/ X2 - X1 = -9-(2)/ -7-(9) = -11/ -16

The slope of the line is 11/16.

The slope of any given formula can be found as

Slope = (y2 - y1)/(x2 - x1)

Where, y2 and y1 are the y-coordinates of the given two points

and, x2 and x1 are the x-coordinates of the given two points.

By the problem, y2 = -9 , y1 = 2 , x2 = -7 and x1 = 9

Using the above identity,

Slope = (-9 - 2) / (-7 - 9)

∴ Slope = -11 / -16 = 11/16 = 0.6875

Thus the slope of the line containing given points is 11/16

Step-by-step explanation:

(4.2- 4.0)/4.0 * 100 = 5%

Answer:

The percent of increase in the cost of gasoline, from May to June, is 5%.

Step-by-step explanation:

We were given the following:

In May the price of gasoline was $4.00 and in June the price went up to $4.20.

We can determine the percent increase as follows:

percentage increase in gasoline(%) = ((final price-original price)/final price)*100

let y be the final percentage increase of gasoline.

[tex]y=((4.2-4)/4.2)*100=5[/tex]

So the increase of gasoline as 5%

We can check this by multiplying the original prices by 5% and adding the original price.
