Identify the independent and dependent variable for the given situation. The amount of
distance covered by a car in a certain amount of time.
Answer:
distance = independant; time = dependant
Step-by-step explanation:
You are able to change the distance you travel, making it the independant. As you go farther, the time increases, so it is dependant on the distance traveled, therefore it is the dependant.
Express this amount in dozens. (Use decimal form.) 75 cupcakes
Answer:
6.25 dozens for 75 cupcakes
Step-by-step explanation:
(used a calculator... if I'm wrong, I'm sorry TmT
Answer:
6.25 dozens
Step-by-step explanation:
1 dozen = 12
75 / 12 = 25 / 4
25 / 4 = 6 1 /4 = 6.25
solve for the given variable
Answer:
30
Step-by-step explanation:
Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!
Answer:
k = 30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle, thus
k + 90 = 120 ( subtract 90 from both sides )
k = 30
What is the slope-intercept equation for the line below? (5, 4) (0, 2) 6 +
O A. y=x+2
O B. y=-x+2
O C. y=-x+2 O 2/
D. y=x+2
Answer:
The answer is D y=2/5x + 2
Step-by-step explanation:
I find the the slope first by using the slope formula y2 - y1/x2 - x1
Then, I use the slope-intercept formula to find the y-intercept
4 = 2/5(5) + b
4 = 10/5 + b
4 = 2 + b
4 - 2 = 2 - 2 + b
2 = b
So u get:
y=2/5x + 2

Step-by-step explanation:
An arrow is shot vertically upward from a platform 35 ft high at a rate of 166 ft/sec. When will the arrow hit the ground? Ignore the air resistance. Use the formula ℎ = −16 2 + 0 + ℎ0. Round your answer to the nearest tenth.
Answer:
The arrow will hit the ground approximately 10.5 seconds after launch.
Step-by-step explanation:
The arrow experiments a free fall motion, which is a particular form of uniform accelerated motion due to gravity and in which air friction and effects from Earth's rotation can be neglected. Then, the height as a function of time ([tex]h(t)[/tex]), measured in feet, is obtained by the following kinematic formula:
[tex]h(t) = h_{o}+v_{o}\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]h_{o}[/tex] - Initial height of the arrow, measured in feet.
[tex]v_{o}[/tex] - Initial velocity of the arrow, measured in feet per second.
[tex]t[/tex] - Time, measured in seconds.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
If we know that [tex]h(t) = 0\,ft[/tex], [tex]h_{o} = 35\,ft[/tex], [tex]v_{o} = 166\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{m}{s^{2}}[/tex], then the following polynomial is obtained:
[tex]35+166\cdot t -16.087\cdot t^{2}=0[/tex] (2)
Lastly, we find the roots of the given expression by the Quadratic Formula:
[tex]t_{1}\approx 10.526\,s[/tex] and [tex]t_{2} \approx -0.207\,s[/tex]
Time is a positive variable and then we conclude that the only solution that is physically reasonable is approximately 10.526 seconds.
The arrow will hit the ground approximately 10.5 seconds after launch.

I have a box that is 5 inches wide, 2 inches deep, and 4 inches tall that I want
to fill with sand. How much sand can I fit inside my box?
Answer:
40in^3Step-by-step explanation:
Step one:
given data
dimension of the box
lengh= 5 in
width= 2 in
height =4 in
Required
the volume of the box
the expression for the volume is
V=L*W*H
V=5*2*4
V=40 in^3
Hence the volume of sand the box can take is 40in^3
Jack left a tip of $5.75 for his waiter. If this represents 20% of his meal, what was the cost, in dollars, of Jack’s meal without the tip?
Answer:
Step-by-step explanation:
This is a commission problem. Here is the formula:
P x R
= 5.75 x 0.20
= $1.15
Jack's tip was $1.15. :D
Key: P = Original Price R = Commission Rate
Reed has made 78 of 90 attempted free
throws last season. How many
consecutive free throws must he make to
bring his free throw percentage to 90%?
Answer: 81 consecutive free throws
Step-by-step explanation: Since 78 of 90 attempted free throws equals to 88.89%, then try adding 3 to 78, (78 + 3) which equals to 81. If you convert 81/90 to a percentage, you get 90%. So your final result or answer is 81 consecutive free throws.
Tip: To convert a fraction to a percentage, divide the denominator by the numerator and you should get a decimal quotient. Lastly, just add a percentage sign.
A biker can travel 8 miles in one hour. How long will it take him to travel 32 miles?
Create a table. Highlight the unit rate. State your answer clearly with a label.
Answer:
4hrs
Step-by-step explanation:
Given parameters:
Rate of the biker = 8mph
Unknown:
Time taken to travel 32miles = ?
Solution:
We have been given the speed of the bike which is 8mp.
Speed is the distance covered per unit of time. It is mathematically expressed as;
Speed = [tex]\frac{distance}{time}[/tex]
So,
Time = [tex]\frac{distance }{speed }[/tex]
Now, insert the parameters and solve;
time = [tex]\frac{32}{8}[/tex] = 4hrs

What is the rate of change of the following equation?
y=x-5
Step-by-step explanation:
rate of change =y/x
= _5
rate of change = 1
What is rate of change?Rate of Change: The speed at which a variable changes over a specific period of time. It is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another. Graphically, this ratio is represented by the slope of a line.
Given equation:
y = x - 5
rate of change = m = ?
Comparing the equation with slope intercept form of line
y = mx + c
slope m = 1
c = -5
Hence the rate of change (slope m) = 1

Answer: 26
Step-by-step explanation: Since you are given the measures of two legs which are 24 (XY) and 10 (XS), you just need to use the formula a^2+b^2=c^2 to find the hypotenuse which is RY.
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
