David says,
“72 kilometres per hour is faster than 20 metres per second."
(b) Is David correct?
You must show how you get your answer.
Answer:
no, 72 km/hr is equal to 20m per sec
Step-by-step explanation:
20 m = .02 km
.02 km per hour is equal to .02(3600) per hour, which is 72 km per hour
(you have to multiply my 3600 to get seconds into hours)

Answer:
statement: segment HA is parallel to seg HD and seg HD is parallel to seg AN.
Reason: given
statement: angle 1 is congurent to angle 3.
reason: alternate interior angles are congruent.
statement: angles 2 and 4 are congruent
reason: alternate interior angles are congruent.
statement: Seg DA is congruent to seg DA
reason: reflexive property
statement: angle AHD is congruent to angle AND
reason: since angles 1 and 3 are congruent, and 2 and 4 are congruent, and HDA is a triangle, same with AND, the last angle must be congruent.
statement: seg HD is congruent to seg NA and HA is cong to ND.
reason: ASA angle side angle theorem states that if 2 angles and a side is congruent to the corresponding parts of another triangle, then it is congruent.

A high school drama club is performing a musical to benefit a local charity. Tickets are $5. They also receive donations if $500. They wants to raise at least $2000. How many tickets should they sell to reach their target
Answer: 300 tickets
Step-by-step explanation:
The drama club wants to raise at least $2,000. They have already received donations of $500 so the amount left till target is:
= 2,000 - 500
= $1,500
Tickets are being sold at $5 so the number of tickets needed to get to $1,500 is:
= 1,500/5
= 300 tickets

In the expression 3x - 4y + z, what is the
coefficient of z?
Answer:
1
Step-by-step explanation:
The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.
The coefficient of z in the expression 3x- 4y +z is 1.
What is expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
3x - 4y + z
As, we know a coefficient is a number that is multiplied by a variable.
So, the coefficient of x is 3, coefficient of y is 4 and coefficient of z is 1.

For the polynomial state a common factor of all monomials and factor it out. 3/2*x^2yz-9/8*xyz+15/4*xy
Answer:
3/2x²yz – 9/8xyz + 15/4xy = 3/2xy[xz – 3/4z + 5/2)
Step-by-step explanation:
Given 3/2x²yz – 9/8xyz + 15/4xy. Let's look for a common factor.
3/2x²yz = 3/2 * x * y * z
9/8xyz = 3/2 * 3/4 * x * y * z
15/4 = 3/2 * 5/2 * x * y
Looking at the above; 3/2, x and y are common to all terms. Therefore the factor is:
3/2xy. Now let's factor it from each term
3/2x²yz = 3/2xy(xz)
9/8xyz = 3/2xy(3/4z)
15/4xy = 3/2xy(5/2), therefore we have:
3/2x²yz – 9/8xyz + 15/4xy = 3/2xy[xz – 3/4z + 5/2).
Determine whether statement (3) follows from statements (1) and (2) by the Law of Detachment or the Law of Syllogism. If it does, state which law was used. If it does not, write invalid.(1) If you use a pencil you can erase mistakes. (2) If you can erase mistakes your paper will be neater. (3) If you use a pencil your paper will be neater. Question
Answer:
Law of Syllogism
Step-by-step explanation:
Remember, the Law of Syllogism simply states that if two statements are true, then a third statement that is true can be derived from it. In other words,
(1) If action p results in q , and
(2) If action q results in r.
Then we can derive a third true statement: that says,
(3) If action p then r.
So in summary,
(1) If you use a pencil (action p), you can erase mistakes (results in q).
(2) If you can erase mistakes (q) your paper will be neater (r).
(3) If you use a pencil (if p) your paper will be neater (then r).
This rightly fits into the law of syllogism.

1 can of tomatoes = 6 teaspoons of Oregano
8 can of tomatoes = x teaspoons
Cross Multiply
x = 8 × 6 teaspoons
x = 48 teaspoons of Oregano

Predict the rate of change for the depth of the diver for the intervals of [3, 4], [4, 5], and [5, 6].
Answer:
The rate of change is 1
Step-by-step explanation:
Given
[tex]\{[3, 4], [4, 5], [5, 6]\}[/tex]
Required
Predict the rate of change
Average rate of change (R) is calculated using:
[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]
Here, we have:
[tex][a,f(a)] = [3,4][/tex] and
[tex][b,f(b)] = [5,6][/tex]
Substitute these values in the above equation
[tex]R = \frac{6 - 4}{5 -3}[/tex]
[tex]R = \frac{2}{2}[/tex]
[tex]R = 1[/tex]
Also, check the rate of change using:
[tex][a,f(a)] = [3,4][/tex] and
[tex][b,f(b)] = [4,5][/tex]
The equation: [tex]R = \frac{f(b) - f(a)}{b - a}[/tex] becomes
[tex]R = \frac{5-4}{4-3}[/tex]
[tex]R = \frac{1}{1}[/tex]
[tex]R = 1[/tex]
Hence, the rate of change is 1

Please use your own words.
Answer:
Prepare. You dread public speaking because you don't know what to say.
Psych yourself. ...
Know your audience. ...
Be an expert on your topic. ...
Visualize. ...
Conduct an ocular inspection. ...
Read, watch, and listen to good speakers.
Step-by-step explanation:
To scope a speech you need to narrow dow. what you are talking about into the relevant topic. A easy way to effectivly scope your speech is to ask yourself "what information do I want my audience to know at the end of my speech." Once you've answered his for yourself, use it as your focal point for your speech. Keep what you're talking about relevant to the purpose and thesis of your speech. And make sure to use anything superfluous or extraneous because it will broaden your scope and take the speech away from the ultimate goal.

Answer:
50mph
Step-by-step explanation:
Step one:
given data

Average speed= 200/4
Average speed= 50mph
Two cars leave towns 760 kilometers apart at the same time and travel toward each other. One car's rate is 12 kilometers per hour less than the other's. If they meet in 4 hours, what is the rate of the slower car
Answer:
89 km/hr
Step-by-step explanation:
Distance = Rate(speed) × Time
D = R × T
T = 4 hours
One car's rate is 12 kilometers per hour less than the other's.
Hence:
First's car's rate = r × 4 = 4r
Second car's distance = (r + 12) × 4 = 4r + 48
4r + 4r + 48 = 760
8r + 48 = 760
8r = 760 - 48
8r = 712
r = 712/8
r = 89 km/hr
The rate of the slower car is 89 km/hr
Write and solve a real-world problem that can be represented by the expression (–3)(5), then solve it
Answer and explanation:
(-3)(5) evaluates to -3×5=-15
A real world problem that would represent this would be a case where 5 fruit vendors each give out 3 fruits to 3 of their customers in the spirit of Christmas. Each vendor gives out(subtracts fruits from fruit stock) 3 of their fruits= -3 fruits for each vendor. There are a total of 5 fruit vendors therefore -3×5= -15 fruits given out by all 5 fruit vendors in total. To better understand this, we could compare this to if the vendor were to get(add to stock of fruits) fruits and not actually give out fruits. This would be 3×5= 15 fruits gotten by all the 5 vendors in total.
