Mrs. Oakes drove for 2 hours and went 50 miles. She then drove 3 more hours an
went 60 miles. What was her average speed for the whole journey?
Options
-22 miles per hour
-37 miles per hour
-42 miles per hour
-75 miles per hour
Can someone help me please
9514 1404 393
Answer:
22 miles per hour
Step-by-step explanation:
Her average speed for the journey is found by dividing the total distance by the total time:
(50 mi + 60 mi)/(2 h + 3h) = (110 mi)/(5 h) = 22 mi/h

Let x denote the average number of hours per week that a student at Happy High School spends doing homework. Suppose the frequency distribution of x is normal (i.E., symmetrical and bell-shaped) with a mean of 3.4 hrs. And a standard deviation of 2.6 hrs. What percentage of the students at Happy High spend an average of less than 6 hours per week doing homework?
Answer:
0.84134
Step-by-step explanation:
Given that:
Mean = 3.4 hours
Standard deviation (s) = 2.6 hours
Percentage of students that spend less than 6 hours doing homework
P(x < 6)
Using the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (6 - 3.4) / 2.6
Z = 2.6 / 2.6
Z = 1
p(Z < 1) = 0.84134 ( Z probability calculator)
The percentage of the students at Happy High spends an average of less than 6 hours per week doing homework is 0.84134

Prove that tan22° + tan23° + tan22°. tan23° = 1
Answer:
Hope you got it....
Step-by-step explanation:
1=tan45∘
1=tan(22∘+23∘)
1=tan22∘+tan23∘1−tan22∘tan23∘
1−tan22∘tan23∘=tan22∘+tan23∘
1=tan22∘+tan23∘+tan22∘tan23∘
It will be the same for any two angles that add up to 45∘.
Answer:
ooo....
Step-by-step explanation:
22° + 23° = 45°
taking tan on both side
or,tan(22° + 23°)=tan45°
or,(tan22° + tan23°)/(1-tan22°. tan23°)=1
or,tan22° + tan23° =1- tan22°. tan23°
or,tan22° + tan23° + tan22°. tan23° = 1

The formula for the circumference of a circle is c=2pir where r is the radius and c is the circumference. The equation r is r=c/2pi
Answer:
r = 8
Step-by-step explanation:
The circumference of a circle is given by :
[tex]C=2\pi r[/tex] ...(1)
We need to find the value of r when C = 16π
Solving equation (1)
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{16\pi}{2\pi}\\\\r=8[/tex]
So, the value of r is 8. Hence, the correct option is (b).
Heres a graph of a linear function. Write the equation that describes that function.
Answer:
Y=[tex]\frac{1}{3}[/tex]X-4
Step-by-step explanation:
Using the slope-intercept equation, a line is given as y=mx+b, where m represents the slope and b represents the y-intercept. From this graph, we can see that the slope is 1/3 and this line meets the y-axis at -4.
Thus, using that information, we substitute this into the equation to get
y= (1/3)x - 4

What is the x-intercept of the line?
Answer:
- 1
Step-by-step explanation:
y = mx + b ( "m" is slope and "b" is y-intercept )
The equation of a given line is
y = - 2x - 2
Coordinates of x-intercept are ( x, 0 ) ⇒ 0 = - 2x - 2 ⇒ x = - 1
The x-intercept of the line is ( - 1 )

A 60 ounce glass bottle of juice sells for $4.20 while a 1.5 liter of the same juice sells in a plastic bottle for $3.06. Compare the unit prices of the juice for the two containers. (1 liter is approximately 34 ounces)
The answer is letter b. $4.20 / 60 ounce is the rate for the glass bottle while $3.06 / 51 ounces is the rate for the plastic one. Simplified, the glass bottle is $0.07 / ounce while the plastic bottle is $0.06 / ounce.
What's the next number? 0 , 1/3 , 1/2 , 3/5 , 2/3
Answer:
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 is 5/7
Step-by-step explanation:
The given numbers are;
0, 1/3, 1/2, 3/5, and 2/3
The number sequence is formed adding [tex]\dfrac{1}{\left (\dfrac{n^2 + n}{2} \right ) }[/tex] to each (n - 1)th term to get the nth term number in the sequence, with the first term equal to 0, as follows;
For the 2nd term, the (n - 1)th term is 0, and n = 2, gives;
The
[tex]0 +\dfrac{1}{\left (\dfrac{2^2 + 2}{2} \right ) } = 0 + \dfrac{1}{3} = \dfrac{1}{3}[/tex]
For the 3rd term, the (n - 1)th term is 1/3, and n = 3, gives;
[tex]\dfrac{1}{3} +\dfrac{1}{\left (\dfrac{3^2 + 3}{2} \right ) } = \dfrac{1}{3} + \dfrac{1}{6} = \dfrac{1}{2}[/tex]
For the 4th term, the (n - 1)th term is 1/2, and n = 4, gives;
[tex]\dfrac{1}{2} +\dfrac{1}{\left (\dfrac{4^2 + 4}{2} \right ) } = \dfrac{1}{2} + \dfrac{1}{10} = \dfrac{3}{5}[/tex]
For the 5th term, the (n - 1)th term is 3/5, and n = 5, gives;
[tex]\dfrac{3}{5} +\dfrac{1}{\left (\dfrac{5^2 + 5}{2} \right ) } = \dfrac{3}{5} + \dfrac{1}{15} = \dfrac{2}{3}[/tex]
For the next or 6th term, the (n - 1)th term is 2/3, and n = 6, gives;
[tex]\dfrac{2}{3} +\dfrac{1}{\left (\dfrac{6^2 + 6}{2} \right ) } = \dfrac{2}{3} + \dfrac{1}{21} = \dfrac{15}{21} = \dfrac{5}{7}[/tex]
The next number of the series 0, 1/3, 1/2, 3/5, and 2/3 = 5/7.
4x?x2=48
by the way i'm unsmart I just wanted to show my little brother how brainly works
Answer:
6
Step-by-step explanation:
So I assume it's 4 × x × 2 = 48
First multiply the like terms (4 x 2) and you'll get 8.
8 × x = 48
Then you 8 by the x and get 8x
8x = 48.
Lastly you'll just divide 48 by 8 and get 6.
Hope your brother understands how this works now! (It's basically legal cheating)
