Terrance's homework grade was a 72, his project grade was an 80 and his exam grade was an 82.
Homework is worth 10% of the final grade, the project was worth 50%, and the exam was worth 40%.
What was Terrance's final grade?
Answer:
80%
Step-by-step explanation:
home work = 10%
project grade = 50%
final exam = 40%
so
homework = 72
100=10
72=? cross multiply and get 7.2%
project grade = 80
100 = 50
80 = ? cross multiply and get 40%
final exam = 82
100 = 40
82 = ? cross multiply and get 32.8%
then add them altogether getting a total of 80%.

Hector knows there is a relationship between the number of cars and the time it takes him to was it
Wats the independent quantity and dependent quantity
The independent quantity is time and dependent quantity is number of cars washed .
Independent variables are variables that are manipulated or modified by the experimenter and are assumed to directly influence the dependent variable. For example, assign participants to a drug or placebo condition (independent variable) and measure changes in anxiety intensity (dependent variable). The dependent variable is the variable that is tested and measured in the experiment and is the "dependent". ' about the independent variable. An example of a dependent variable is depression symptoms that depend on the independent variable (type of treatment).In the given relation between the number of cars and the time .
The relationship between the number of cars he washes and the time it takes to wash those cars represents a proportional variation
Let y -----> number of cars he washes

O-5x>-18
O-5x > 18
O-5x > 10
10. (01.04 MC)
Answer:
-5x > 10
Step-by-step explanation:
1. We know that when -14 thrown to the right hand side, it will turn to +14
2. +14 -4 = +10
3. Left hand side will remain -5x
4. Hence, -5x > 10
5. and the equation divided by -5, the > sign will change to <
6. x< -2
7. Since you're finding the missing step so it's -5x > 10
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11 A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10 How much does a liter of milk cost, and how much does a loaf of bread cost?
Answer:
A liter of milk cost $0.75 and a loaf of bread cost $1.75
Step-by-step explanation:
Let the liters of milk by represented by m
Let the loaves of bread by represented by b
Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11
3m + 5b = 11...... Equation 1
A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10
4m + 4b = 10.... Equation 2
Combining the Equations
3m + 5b = 11...... Equation 1
4m + 4b = 10.... Equation 2
We solve using the Elimination method
Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m
12m + 20b = 44..... Equation 3
12m + 12b = 30....... Equation 4
Substract Equation 4 from Equation 3
8b = 14
b = 14/8
b = $1.75
Solving for m
3m + 5b = 11...... Equation 1
3m + 5($1.75) = 11
3m + $8.75 = $11
3m = $11 -$ 8.75
3m =$ 2.25
m =$ 2.25/3
m = $0.75
Therefore,
a liter of milk cost $0.75 and a loaf of bread cost $1.75

Find m/BCE and mZECD.
Answer:
BCE= 115 ECD=65
Step-by-step explanation:
(5x+10)+(3x+2)=180
8x+12=180
8x=168
x=21
5(21)+10=115
3(21)+2=65
Answer:
<BCE=115°
<ECD=65°
And their sum is 180°
Step-by-step explanation:
< BCE + <ECD =180° ( Being sum of supplementary angle which is formed in the given diagram is 180°)
(5x + 10)° + (3x + 2)°= 180°
5x + 10 + 3x + 2 = 180°
5x + 3x + 10 +2 = 180°
8x + 12= 180°
8x = 180°-12°
8x = 168
x= 168/8
x=21°
Now,
<BCE = 5x+10
= 5*21+10
=105+10
=115
<ECD
= 3x+2
= 3*21+2
=65

A squirrel has stored its acorns in a hole that is 45 feet from the ground in a tall tree. The squirrel moved from a perch 100 feet above the ground to get to its stored acorns in 5.25 seconds. Interpret the quotient to describe the rate of change in the squirrel’s height above the ground. Give your answer to the nearest hundredth.
The quotient to describe the rate of change in the squirrel’s height above the ground is 27.619 feet per seconds to the nearest hundredth.
How to find the rate of change in the squirrel’s height above the ground.Given data
height below ground = 45 feet
height above the ground = 100 feet
time of travel = 5.25 seconds
Rate of change calculation
total distance moved by the squirrel = height below ground + height above the ground
= 45 feet + 100 feet
= 145 feet
rate of change = total distance / time of travel
= 145 feet / 5.25 seconds
= 27.619 feet per seconds

A train leaves at 17.22 and arrives at its destination at 18.14.
If the train travelled 56 km, what was it's average speed in km/h?
Give your answer rounded to 1 dp.
Answer:
48.5 km/h
Step-by-step explanation:
speed = distance/time
distance =56km
time = 1814h - 1722h
time = 52 min = 52/60h =13/15h
speed = 56*13/15
speed = 48.53
into 1dp= 48.5 km/h
Answer =
So first remember the formula:
Distance/Time= Speed.
Now you see how many minutes it is from 17:22 to 18:14.
17:22 > 18.14 = 52 minutes, 1 Hour = 60 minutes. Hence, 52/60.
Then you get your calculator and do, 56 km/ 52/60
So what I mean is basically 56 km *fraction line* 52 *another fraction line* and then 60 in your calculator. Then you will get a fraction then press SD in your calculator.
You should get 64.6153....
Now the final step is to round it to the 1st decimal place, so
64.6|153 after 64.6 is the first decimal place which is (1) and 1 is below 5 so it will not go up and therefore stay the same so, your Answer is: 64.6 km/h.

The cost to rent a rug cleaner is $25 plus $15 per hour at Floors, Inc. At Rugs R Clean the rug cleaner costs $45 plus $7 per hour. Which inequality can be used to show how many hours you need to rent the rug cleaner so that Floors, Inc.'s charges will be same the charges at Rugs R Clean?
Answer:
25 + 15x < 45 + 7x
Step-by-step explanation:
Given:
Floors, Inc. Fixed charges = $25
Floors, Inc. Variable charges = $15 per hour
R rug clean Fixed charges = $45
R rug Variable charges = $7 per hour
Computation:
Assume number of hour = x
Floors, Inc. total cost = 25 + 15x
R rug total cost = 45 + 7x
So,
25 + 15x < 45 + 7x

What is the exact value of tan(195°)?
Given:
The value is tan(195°).
To find:
The exact value of tan(195°).
Solution:
We have,
[tex]\tan (195^\circ)=\tan (180^\circ+15^\circ)[/tex]
[tex]\tan (195^\circ)=\tan (15^\circ)[/tex] [tex][\because \tan (180^\circ-\theta)=\tan \theta][/tex]
It can be written as
[tex]\tan (195^\circ)=\tan (45^\circ-30^\circ)[/tex]
[tex]\tan (195^\circ)=\dfrac{\tan (45^\circ)-\tan (30^\circ)}{1+\tan (45^\circ)\tan (30^\circ)}[/tex] [tex][\because \tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}][/tex]
[tex]\tan (195^\circ)=\dfrac{1-\dfrac{1}{\sqrt{3}}}{1+(1)(\dfrac{1}{\sqrt{3}})}[/tex]
[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{1+\dfrac{1}{\sqrt{3}}}[/tex]
[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{\dfrac{\sqrt{3}+1}{\sqrt{3}}}[/tex]
[tex]\tan (195^\circ)=\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex]
Therefore, the exact value of tan(195°) is [tex]\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex].
