Tara earns $8.00 per hour for babysitting. Which expression represents how much Tara earns for h hours of babysitting? 4 83
Answer:
Total amount Tara earned for babysitting for h hours = 8h
Step-by-step explanation:
Amount earned per hour for babysitting = $8.00
Number of hours of babysitting = h hours
Total amount Tara earned for babysitting for h hours =
Amount earned per hour for babysitting × Number of hours of babysitting
= 8 × h
= 8h
Total amount Tara earned for babysitting for h hours = 8h

Ross and Ronnie are late for their favorite show . Ross walks around a rectangular park with dimensions of 150 ft by 215 ft. Ronnie decides to cut across the park in a diagonal path. Who walks the shortest distance and by how much? *
Answer:
Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft
Step-by-step explanation:
The image attached represent the rectangular park. In this case, the dimensions are;
AB = CD = 215 ft
AC = BD = 150 ft
Total distance walked by Ross = AB + BD = 215 + 150 = 365 ft
Distance walked by Ronnie = AD
∠ABD = right angle triangle, using pythagoras rules;
AD² = AB² + BD²
AD² = 215² + 150²
AD² = 68725
AD = √68725
AD = 262.15 ft
Distance walked by Ronnie = 262.15 ft
Ronnie walked the shortest distance by (365 - 262.15 ) = 102.85 ft

if f(x)=3, what is f(4)= ?
Answer:
12
Step-by-step explanation:
Since f(x) = 3, you would multiply 3 by 4. This is because you are basically saying that you have 4 x's and each x is equal to 3. 3+3+3+3=12 or 4(3)=12

If the mean of a normal distribution is 26 what is the median of the distribution A. 18 B. 14 C. 26 D. 22
Answer:
C. 26
Step-by-step explanation:
Since in the question it is mentioned that the mean of the normal distribution is 26 and also as we know that the normal distribution considered to be symmetric so the mean would be equivalent to the median
As in the question the mean is 26 so the median would also be 26
hence, the correct option is C.

A TV that usually sells for $180.18 is on sale for 15% off. If sales tax on the TV is 5%, what is the price of the TV, including
tax?
A. $162.34
B. $214.86
C. $160.81
D. $159.28
Answer:
C, $160.81
Step-by-step explanation:
180.18 decrease 15% =
180.18 × (1 - 15%) = 180.18 × (1 - 0.15) = 153.153
153.153 increase 5% =
153.153 × (1 + 5%) = 153.153 × (1 + 0.05) = 160.81065

Anyone can help me with math for solving for a side in the right triangles for khan academy
Answer:
7.45
Step-by-step explanation:
We are given a right triangle with one side length known and an angle know so we can use some trigonometry.
You need to find the hypotenuse so you are going to use either sine or cosine.
Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,
cos(20) = 7/h
=>h = 7/cos(20)
=> 7.44924
=> 7.45
What is the distance (in units) between points C and D? Round your answer to the nearest hundredth. c(-5,-1) d(0,3)
Answer:
6.4
Step-by-step explanation:
The whole thing is like a triangle, with the distance between the points as the hypotenuse.
Use the pythagorean theorem, a²+b² = c².
To calculate a, calculate the distance between the x-values of (-5,-1) and (0.3) by subtracting.
0-(-5) = 5
a = 5
To calculate b, calculate the distance between the y-values of (-5,-1) and (0.3) by subtracting.
3-(-1) = 4
b = 4
now plugin a = 5 and b = 4 into the pythagorean theorm to calculate c, or the distance.
5²+4² = c²
25+16 = c²
41 = c²
√41 = √c²
c = 6.4
