A-) who won the race? a1)By how many yards of difference? B-) How many yards behind the starting line does Yolanda have to leave for the race to end in a draw?

Answers

EXPLANATION

Let's see the facts:

Race = 100-yard

Toko--> 10 yards < Yolanda

Second part:

Yolanda --> 10 yards behind the starting line

If each geil ran at the same speed as the first race, the appropiate relationship is as follows:

Yolanda's speed = 100 yards/race

Yoko's speed = 90 yards/race

Distance= ratex time

For the second race, Yolanda ran 110 yards at the same speed --> So it will take 110/100 = 1.1 times to finish the race.

Yoko runs 100 yards at the same speed so it will take her 100/90= 1.11111... times to finish the run.

As 1.11 is less time than 1.1111, Yolanda will win the race.

b) In order to finish in a tie, the times must be the same.

Let x be the head start given to Yoko so that they tie.

time = distance / rate

[tex]\frac{100+x}{100}=\frac{100}{90}[/tex]

Multiplying both sides by 100:

[tex]100+x=100\cdot\frac{100}{90}[/tex]

Subtracting -100 to both sides:

[tex]x=100\cdot\frac{100}{90}-100[/tex]

Simplifying:

[tex]x=111.11111\ldots-100=11.111\ldots[/tex]

So, if Yoko has 11.111... head start, they should tie on the next race.


Equation: y =
Write an equation of the line that passes through the given point and is parallel to the given I
(-4, 2); y = 1/4x + 1

Answers

The equation of the line that passes through the point (-4,2) and the parallel to the line y = 1/4x + 1 is y = (1/4)x+3

The equation of the line parallel to the line is

y = 1/4 x +1

The slope intercept form is

y = mx + b

Where m is the slope of the line and b is the y intercept

By comparing the given equation and slope intercept form of the line

The slope of the line is m = 1/4

Then the point slope form is

[tex](y-y_1)= m(x-x_1)[/tex]

The line is passing through the point (-4,2)

Substitute the values in the equation

(y-2) = 1/4(x-(-4))

y-2 = 1/4(x+4)

y-2 = (1/4)x+1

y = (1/4)x+3

Hence, the equation of the line that passes through the point (-4,2) and the parallel to the line y = 1/4x + 1 is y = (1/4)x+3

find the x and y intercepts of 2x-5y=12 (write all answers as points)

Answers

[tex]\begin{gathered} x-\text{intercept is (6,0)} \\ y-\text{intercept is (}0,\text{ -}\frac{12}{5}) \end{gathered}[/tex]

Here, we want to find the x and y intercepts of the given line

We start by writing the equation of the line in the standard form

The standard form is;

[tex]y\text{ = mx + b}[/tex]

where m is the slope and b is the y-intercept

We have the equation re-written as;

[tex]\begin{gathered} 5y\text{ = 2x - 12} \\ y\text{ = }\frac{2}{5}x\text{ - }\frac{12}{5} \end{gathered}[/tex]

As we can see, we have the y-intercept at the point y = -12/5

The coordinate form at this point is (0,-12/5)

To find the x-intercept, we simply set y to zero

This is;

[tex]\begin{gathered} 0\text{ = }\frac{2}{5}x\text{ - }\frac{12}{5} \\ \\ \frac{2}{5}x\text{ = }\frac{12}{5} \\ \\ 2x\text{ = 12} \\ x\text{ = }\frac{12}{2} \\ x\text{ = 6} \end{gathered}[/tex]

The x-intercept is thus (6,0)

7. Write the slope-intercept form of the equation of the line through the given point with the given slope. Write answer as y=mx+b. through: (-1, 1), slope = -6 Vour answer

Answers

Answer:

y = -6x - 5

Explanation:

The equation of a line with slope m that passes through the point (x1, y1) can be calculated using the following equation:

[tex]y-y_1=m(x-x_1)[/tex]

So, replacing (x1, y1) by (-1, 1) and m by -6, we get:

[tex]\begin{gathered} y-1=-6(x-(-1)) \\ y-1=-6(x+1) \end{gathered}[/tex]

Now, to write the answer as y = mx + b, we need to solve the equation for y, so we get:

[tex]\begin{gathered} y-1=-6(x)-6(1) \\ y-1=-6x-6 \\ y-1+1=-6x-6+1 \\ y=-6x-5 \end{gathered}[/tex]

Therefore, the answer is y = -6x - 5

Answers

The image contains a figure in which angles and sides are named, some data is given, and the proof is to be provided.

Every proof starts with the given data.

Thus, from the options, we select those containing the information provided:

a) BD is parallel to CE

d) Angle 5 is congruent to angle 6

Now we can see the segments AB and AD have one tick mark. This means they are congruent or have the same measure.

AB is congruent to AD

The triangle ABD, having two equal sides, is isosceles. Every isosceles triangle has two congruent angles, in this case, angles 5 and 6.

Thus, the next step in the proof is:

c) Angle 5 is congruent to C and angle 6 is congruent to E

Because of the transitive property of congruence, it follows:

e) Angles C and D are congruent

Being two angles in a triangle congruent, it follows the triangle is isosceles, thus:

b) AC and AE are congruent

This is the final step of the proof

2.

after 63 months = 5.25 years (t = 5.25)

2000 × (1.025)^(2×5.25) = 2000 × (1.025)^10.5 =

Suppose 72% of students chose to study French their freshman year, and that meant that there were 378 such students. How many students chose not to take French their freshman year?

Answers

The number of students who chose not to take French their freshman year is 147.

According to the question,

We have the following information:

72% of students chose to study French their freshman year.

Now, 72% of students is equal to 378.

Let's take the number of students to be x.

So, we have:

72x/100 = 378

72x = 378*100

x = (378*100)/72

x = 525

Now, we have to find the number of students who chose not to take French their freshman year:

(100%-72%)

28%

Now, we have to find the 28% of total number of students:

(28*525)/100

14700/100

147

Hence, the number of students who chose not to take French their freshman year is 147.

The equation of the line that passes through point (8,-1) and perpendicular to 8y = x - 16 is f(x) = -8x + 63.

What is the equation of line that passes through the given points and is perpendicular to the given line?

Given the data in the question;

Equation of line: 8y = x - 16Point: (8,-1)

First we determine the slope of the initial line using the slope intercept-form. y = mx + b

8y = x - 16

y = (1/8)x - 2

Compared with the slope intercept form,

Slope m = 1/8

Now, for the equation of line perpendicular to the initial line, its slope must be a negative reciprocal of the initial slope.

Hence, slope of the perpendicular line is;

Slope m = -1/1/8 = -8

To find the equation of the perpendicular line, we use the point slope formula.

y - y₁ = m( x - x₁ )

Plug in the slope m ( -8) and point (8,-1).

y - (-1) = (-8)( x - 8 )

y+1 = -8x + 64

y = -8x + 64 - 1

y = -8x + 63

Therefore, the equation of the perpendicular line is y = 8x + 63

Find the probability of selecting a 10 or diamond when a card is drawn from a standard deck of cards.

Answers

The probability of selecting a 10 or Diamond when a card is drawn from a standard deck of cards is: 17/52

The question asks us to find the probability of picking a 10 or diamond from a deck of cards.

A standard deck of cards contains 52 cards in total.

The deck contains 4 "10s"

And the deck also contains 13 diamond cards.

Thus, we can find the probability of drawing a "10" as:

[tex]P(10)=\frac{n\text{umber of 10s}}{total\text{ number of cards in deck}}=\frac{4}{52}[/tex]

Similarly, we can find the probability of drawing a diamond as:

[tex]P(\text{diamond)}=\frac{n\text{umber of diamonds}}{total\text{ number of cards in deck}}=\frac{13}{52}[/tex]

Now that we have the individual probabilities, we can find the probability of drawing a 10 or a diamond using the OR probability:

[tex]\begin{gathered} P(A\text{ OR B)= P(A) + P(B)} \\ \text{where, A and B are independent events} \end{gathered}[/tex]

Therefore, we can solve the question. This is done below:

[tex]\begin{gathered} \text{Probability of selecting a 10 or a diamond P(10 OR Diamond)=} \\ P(10)+P(\text{Diamond)} \\ \\ \text{But P(10)=}\frac{4}{52} \\ P(\text{Diamond)}=\frac{13}{52} \\ \\ \therefore P(10\text{ OR Diamond)=}\frac{4}{52}+\frac{13}{52}=\frac{17}{52} \end{gathered}[/tex]

Thus, the probability of selecting a 10 or Diamond when a card is drawn from a standard deck of cards is: 17/52

Instructions for a chemical procedure state to mix salt, baking soda, and water in a 22 : 14 : 5 ratio by mass. How many grams of baking soda would be required to make a mixture that contains 55 grams of salt?

Answers

35 grams of baking soda will be required for the mixture

The ratio of mix salt to baking soda to water = 22:14:5

Let x be the total quantity of the mixture

A mixture is a substance composed of two or more unrelated chemical components. A physical blending of two or more substances that maintains their own identities takes the form of solutions, suspensions, or colloids.

Now the sum of the ratio is 22+14+5 = 41

So, 55 grams of salt = 22/41x

Solving for x we get:

x = 55*41/22

x = 102.5 grams

The total quantity of the mixture is 102.5 grams

Quantity of baking soda required = 14/41 of 102.5

= 14/41*102.5

= 35 grams
