Answer:
1/4 minutes
Step-by-step explanation:
1 minute = 60 seconds
3 minutes = 180 seconds
3 minutes and 15 seconds = 195 seconds
13 miles/195 seconds
195/13 = 15
His speed --> 1 mile/15 seconds
1/4 minutes = 15 seconds

The following data points represent the number of emails that the CEO of Rock Town Apparel sent each day since he started using a new email client. 6,59,55,106,84,86,96. use the data to create a histogram
Answer:
Frequency density is found when we divide the class width being the days of the week = 7 So that when we see 6 emails its divided by 7 = 6/7 0.857142857 as density 59/7 = 8.42857143 and 55/7 =7.85714286 and 106/7 = 15.1428571 and 84/7 = 12 and 86/7 = 12.285714 and 96/7 =13.7142857 this shows us we need to draw 16 bars up and 7 bars across - The bars across (x line) can be days of the week and the bars going up (y line) an be number of emails if 16 is ore than 106/7 then 16 squares > 106/7 then 15 < 106/7 So we ensure its a proportion of 15.143 and not more than that- and not less than 15.142 for day 4 = 106 emails
A group of 140 high school students were asked, "Do you play a musical instrument?" The results are shown in the table below. If a musician is selected at random, what is the probability that the individual is a female student?
Males - only 24 play instruments and 41 don't
Females - only 43 play instruments and 32 don't
A. 43/140
B. 43/67
C. 43/75
D. 15/28
ANSWER:
A
Step -by -step verification:
Total number of female students that play instruments
Total number of students =43/140
If a musician is selected at random, the probability that the individual is a female student is; 15/28
How to Find the Probability?
We are given;
Total Number of High school students surveyed = 140
Number of males that play instruments = 24
Number of males that don't play instruments = 41
Number of females that play instruments = 43
Number of females that don't play instruments = 32
Thus, If a musician is selected at random, the probability that the individual is a female student is;
P(Female Student) = (43 + 32)/140 = 75/140 = 15/28

A local kids play sold 8 adult tickets and 9 child tickets for a total of $205. On day two they sold only 4 adult tickets and 3 child tickets for a total of $83. What was the price of each kind of ticket?
Answer:
Adult tickets cost $11 and child tickets cost $13
Step-by-step explanation:
Multiply the second equation by -2, then add the equations together.
(8a+9c=205)
−2(4a+3c=83)
Becomes:
8a+9c=205
−8a−6c=−166
Add these equations to eliminate a:
3c = 39
Then solve3c=39for c:
3c=39
[tex]\frac{3c}{3}[/tex] = [tex]\frac{39}{3}[/tex]
(Divide both sides by 3)
c = 13
Now that we've found c let's plug it back in to solve for a.
Write down an original equation:
8a+9c=205
Substitute 13 for c in 8a+9c=205:
8a+(9)(13)=205
8a+117=205 (Simplify both sides of the equation)
8a+117+−117=205+−117 (Add -117 to both sides)
8a=88
[tex]\frac{8a}{8}[/tex] = [tex]\frac{88}{8}[/tex]
(Divide both sides by 8)
a = 11

Hurry Due Today
Answer:
A cup chocolate chips weighs about 9 ounces.
=> 3 cups of chocolate chips weigh about 9 x 3 = 27 ounces.
=> 3/4 cup of chocolate chips weigh about 9 x 3/4 = 27/4 = 6.75 ounces.
=> 3 and 3/4 cups of chocolate chips weigh about 27 + 6.75 = 33.75 ounces.

joe paid 14.00 for a board game. this is 70% of the original price. what is the original price
Answer:
Hello There the Correct answer is 20% start off by finding 10% of $14. in order to find 10%, divide it by 70 which gives 2. you now need to make the 30% to add to the 70%, by timesing the 2 by 3to give 6. now all you need to do it add the 6 to 14 to make 20!
so your answer is $20
Hope it helps!

By what percent will a fraction change if its numerator is decreased by 60% and its denominator is decreased by 20%?
Answer:
decrease by 50%
Step-by-step explanation:
[tex]\frac{0.4x}{0.8y} =\frac{x}{2y}[/tex]
Decreased by 60% = (100%-60%)x = 0.4x.
Decreased by 20% = (100%-20%)x = 0.8x.
[tex]\frac{x}{y}[/tex] initial fraction, and we can see that denominator will increase 2 times, so fraction will decrease 2 times, or decrease by 50%.
Which best explains whether a triangle with side lengths 5 cm, 13 cm, and 12 cm is a right triangle? The triangle is a right triangle because 52 + 122 = 132. The triangle is a right triangle because 5 + 13 > 12. The triangle is not a right triangle because 52 + 132 > 122. The triangle is not a right triangle because 5 + 12 > 13.
Answer:
The Triangle Is A Right Triangle Because 5^2 + 12^2 = 13^2.
Step-by-step explanation:
5^2 = 25. 12^2 = 144. With the Pythagorean theorem, (a^2 + b^2 = c^2), 5 is a, 12 is b, and 13 is c.
25 + 144 = 169.
13 ^ 2 = 169.
Since a^2 + b^2 = c^2 is true, the triangle is a right triangle.
Given:
Sides of triangle= 5cm, 13cm and 12cm
To find: Whether a triangle is a right angled triangle.
This can be solved by applying Pythagorean theorem:
According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
[tex]H^2=P^2+B^2[/tex]
where,
H= Hypotenuse
P= Perpendicular
B=Base
Applying given values in the formula:
[tex]H^2=P^2+B^2\\\\13^2=5^2+12^2\\\\169=25+144\\\\169=169[/tex]
Since, R.H.S= L.H.S
Thus, we can say that this triangle is a right angled triangle.

A segment is m units long. Find the distance between the midpoints of the first and the last parts in each case. a The segment is divided into three equal parts
Answer:
(2/3)m units
Step-by-step explanation:
The segment is m units long. After dividing it into 3 three equal parts, each part is m/3 units long. The midpoint of the first part is located at (m/3)/2 = m/6 units from the beginning of the segment. The midpoint of the last part is located at (2/3)m + m/6 = (5/6)m units from the beginning of the segment. Then, the distance between the midpoints of the first and the last parts is (5/6)m - m/6 = (2/3)m units
Line can be divided into segments.
The distance between the two midpoints is 2m/3
The length of the segment is given as:
[tex]\mathbf{Length = m}[/tex]
The length of each segment, after dividing them into 3 segments is:
[tex]\mathbf{Segment = \frac m3}[/tex]
The midpoint of the first segment is:
[tex]\mathbf{First= \frac m6}[/tex]
The midpoint of the third segment is the sum of the first two segments, and the half a segment
So, we have:
[tex]\mathbf{Third = \frac m3 + \frac m3 + \frac m6}[/tex]
[tex]\mathbf{Third = \frac{5m}{6}}[/tex]
So, the distance between the two midpoints is:
[tex]\mathbf{Distance = \frac{5m}{6} - \frac{m}{6}}[/tex]
[tex]\mathbf{Distance = \frac{5m - m}{6}}[/tex]
[tex]\mathbf{Distance = \frac{4 m}{6}}[/tex]
[tex]\mathbf{Distance = \frac{2m}{3}}[/tex]
Hence, the distance between the two midpoints is 2m/3

R

(25x + 30)
0 25°
w
0 37.59

Answer:
WRS=25 degree
Step-by-step explanation:
Angle VRT + angle TRS = 180 degree (supplementary angles)
5x+25x+30=180
5x+25x=180-30
30x=150
x=150/30=5
Substituting x=5 into angle VRT
5(5)=25
VRT= 25 degree
Looking at the diagram, angle VRT and angle WRS are vertically opposite angle and are therefore equal.
Now, angle WRS= 25 degree
The measure of the angle of intersecting lines ∠WRS = 25°
What are the angles formed by 2 intersecting lines?Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees.
Perpendicular lines are two straight lines that intersect and form right angles. When two perpendicular lines intersect, they form four right angles.
When lines intersect, two angle relationships are formed:
Opposite angles are congruent
Adjacent angles are supplementary
Given data ,
Let the two intersecting lines be a and b
where the measure of ∠SRT = ( 25x + 30 )°
The measure of angle ∠VRT = ( 5x )°
And , the measure of ∠VRT = measure of ∠WRS ( Opposite angles are congruent )
And , the measure of ∠VRT + measure of ∠SRT = 180° ( angles in straight line )
So , 5x + 25x + 30 = 180
30x = 150°
Divide by 30 on both sides , we get
x = 5
Now , the measure of ∠WRS = [ 5 ( 5 ) ] °
Hence , the measure of angle ∠WRS = 25°
