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.

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

Find the area of the shape shown below.
Answer:
18.75
Step-by-step explanation:
The formula to find the area of a triangle is
A= [tex]\frac{1}{2}[/tex]*b*h
The formula to find the area of a rectangle is simply the length times the base.
Here, you can separate the shapes, two triangle and one rectangle to make it easier to find. Subtract 7.5 and 2.5 to get 5, which will be the base measurements for the triangles.
Next, find the area for the triangles: [tex]\frac{1}{2}[/tex] x 5 x 2.5= 6.25, however, you have two triangles, so multiply by two to get 12.5.
Now, find the area of the rectangle, 2.5 +2.5= 6.25
Lastly, add the measurements together, 12.5 +6.25= 18.75

In a complete paragraph, explain how to scope a speech.
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.
Which set of numbers can represent the side lengths, in inches, of an acute triangle?
o 4,5,7
O 5,7,8
O 6,7, 10
O 7.9, 12
Answer:
5 , 7 , 8 represent the side of acute angled triangle
Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that:
Set of numbers.
Now, We use the following result:
When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.
First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.
if sum > Square of last side ⇒ it is Acute Triangle
if sum = Square of last side ⇒ it is Right Triangle
if sum < Square of last side ⇒ it is Obtuse Triangle
a). 4 , 5 , 7
4² = 16 , 5² = 25 , 7² = 49
16 + 25 = 41
Hence, 41 < 49
⇒ It is an Obtuse Triangle.
b). 5 , 7 , 8
5² = 25 , 7² = 49 , 8² = 64
25 + 49 = 74
Hence, 74 > 64
⇒ It is an acute Triangle.
c). 6 , 7 , 10
6² = 36 , 7² = 49 , 10² = 100
36 + 49 = 85
Hence, 85 < 100
⇒ It is an Obtuse Triangle.
d). 7 , 9 , 12
7² = 49 , 9² = 81 , 12² = 144
49 + 81 = 130
Hence, 130 < 144
⇒ It is an Obtuse Triangle.
Therefore, Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

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.

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

From which store should Dylan make his purchase if he wants to get the best price per unit?
Answer:
Store 1
Step-by-step explanation:
Given
See attachment
Required
Determine the store with the best price per unit
It should be noted that the store with the best has the least price per unit.
So, we have:
Store 1
[tex]Quantity = 10\ ft[/tex]
[tex]Price = \$2.50[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$2.50}{10\ ft}[/tex]
Rate = $0.250 per feet
Store 2
[tex]Quantity = 2\ yd[/tex]
[tex]Price = \$1.85[/tex]
Convert quantity to feet
[tex]Quantity = 2 * 3ft = 6ft[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$1.85}{6\ ft}[/tex]
Rate = $0.308 per feet
Store 3
[tex]Quantity = 12\ ft[/tex]
[tex]Price = \$3.40[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$3.40}{12\ ft}[/tex]
Rate = $0.283 per feet
Store 4
[tex]Quantity = 5\ yd[/tex]
[tex]Price = \$4.00[/tex]
Convert quantity to feet
[tex]Quantity = 5 * 3ft = 15ft[/tex]
The unit rate is:
[tex]Rate = \frac{Price}{Quantity}[/tex]
[tex]Rate = \frac{\$4.00}{15\ ft}[/tex]
Rate = $0.267 per feet
From the calculations above; store 1 has the least unit rate.
Hence, store 1 has the best price per unit
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).

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
