In the rectangle below, R V=3 x+8, S V=6 x-4, and m∠ V R S=54°. Find the value of x and m∠ V U R
Answers
From the information given about the above quadrilateral, that is, the rectangle x is equal to 4, and m∠VUR is equal to 36°.
What is a quadrilateral?A quadrilateral is a four-sided polygon with four edges and four corners in geometry. The name comes from the Latin words quadri, a variation of four, and latus, which means "side."
The results above are derived as follows:
To find x note that the diagonals of a triangle are congruent. This means that RT = SU.
⇒ 3x + 8 = 6x - 4 (add 4 to both sides)
3x + 8 + 4 = 6x - 4 + 4
3x + 12 = 6x (Collect like terms over the equation sign)
12 = 6x - 3x
12 = 3x (divide both sides by three)
x = 12/3
x = 4
To derive m∠VUR,
Recall the properties of a rectangle:
Opposites sides a parallelOpposite sides are equalAll internal angles measure 90°The diagonals of a rectangle are equal.Also, note that;
SRU = 90°
hence
∠VRU = ∠SRU - ∠VRS
that is:
∠VRU = 90 -54 = 36°
If ∠VRU = 36°, then
∠VUR = 36° [The diagonals of a rectangle are equal.]
Hence ΔRVU is an Isosceles triangle. Since this is true, and it is also true that the two angles opposite to the equal sides of an isosceles triangle are congruent to each other,
Then indeed, ∠VUR = 36°

Due to increased mailing costs, the new rate will cost publishers $50 million; this is 12.5% more than they
paid the previous year. How much did it cost publishers last year? Round to the nearest hundreds.
Answers
The amount it will cost the publishers last year is 44.4 million
How to calculate the amount it will cost the publishers?The first step is to write out the parameters
The cost of mailing increased for the last one year
Due to this increase, it will cost the publishers $50 million for this current year
The increase is at the rate of 12.5%
The amount it will cost the publishers last year can be calculated as follows
= 12.5/100
= 0.125 + 1
= 1.125
The next step is to calculate last year cost
last year cost= 50/1.125
= 44.4 million
Hence the publishers spent 44.4 million last year

Answers
The relation between speed, distance and time is express as :
[tex]\text{ Sp}eed\text{ =}\frac{Dis\tan ce}{Time}[/tex]Sean and Darryl are racing on a track.
Sean runs 6 miles per hour and gets a 0.25 mile head start.
Speed of Sean = 6
x is the time taken by Sean
So, Distance = speed x Time
Distance travel by sean = 6x
Since, Sean gets a 0.25 mile head start.
So, total distance travel = 6x + 0.25
Darryl runs 0.7 mile per hour faster than Sean,
Speed of darryl = 0.7 + Speed of sean
Speed of daryl = 0.7 + 6
Speed of darryl = 6.7 miles per hour
x is the time taken by Darryl
So, Distance = Speed x Time
Distance = 6.7x
Distance travel by Darryl = 6.7x
Since distance travel by darryl and sean is equal so,
6x + 0.25 = 6.7x

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

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

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)
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 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

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

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

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

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.
