Answer:
B) Associative Property of Multiplication
Step-by-step explanation:
The associative property states you can change where the parentheses (grouping terms) are in a multiplication statement, and you'll get the same product.
More generally:
(a * b) * c = a * (b * c)
Answer:
B) Associative Property Of Multiplication
Step-by-step explanation:
The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
Therefore, changing the grouping of (8x3) or (3x4) does not change the product.
3. For the sequence defined by tn= 3n + 8,
find each indicated term.
a) t1
b) t7
c) t14
Step-by-step explanation:
Hi there!
According to the question;
nth term (tn) = 3n+8
a).
T1 = 3*1+8
= 11
b).
t7 = 3*7+8
= 29
c).
t14 = 3*14+8
= 50
Therefore, t1 = 11, t7 = 29, t14 = 50.
Hope it helps!
Answer:
11, 29, 50
Step-by-step explanation:
To find the appropriate term , substitute the term number into the rule, that is
(a) t₁ = 3(1) + 8 = 3 + 8 = 11
(b) t₇ = 3(7) + 8 = 21 + 8 = 29
(c) t₁₄ = 3(14) + 8 = 42 + 8 = 50
a+b/c=d/4 solve for a
Answer:
a = d/4 - b/c
Step-by-step explanation:
Subtract b/c from both sides. We can subtract a fraction
so
a = d/4 - b/c
To mix a particular shade of purple paint, read paint and blue paint are mixed in the ratio 5:3. To make 80 gallons of this shade of purple paint, how many gallons of red and blue paint should be used?
Answer:
50 gallons of red
30 gallons of blue
Step-by-step explanation:
5 parts of the whole must be red, 3 parts of the whole must be blue, and there are 5+3=8 parts in total.
therefore, 1 part = 80/8 = 10 gallons
red : 5 parts
5×10 = 50 gallons
blue : 3 parts
3×10 = 30 gallons

Solve using elimination
-3x+9y=12
2x-8y=-16
Answer:
x=8 y=4
Step-by-step explanation:
eliminate x: make x of two equation equal to each other
2(-3x+9y=12) : -6x+18y=24 ___[1]
-3(2x-8y=-16) : -6x+24y=48 ___[2]
[2]-[1]= 6y=24
y=4substitute y to any equation;
2x-8y=-16
2x-8(4)= -16
2x= -16+32
2x= 16
x=8Answer:
x=14 and y=6
Step-by-step explanation:
-3x+9y=12.............(i)×2
2x-8y=-16..............(ii)×3
Multiplying equation (i) by 2 and equation (ii) by 3 and adding (i) and (ii)
-6x+18y=12
6x-24y=-48
-----------------
0-6y=-36
or, -6y=-36
So,y=6
From (i)
-3x+9y=12
or,-3x+9×6=12
or,-3x+54=12
or,-3x=12-54
or,-3x=-42
So,x=14

J (0 , -10)
gradient/slope(m) = 2.
We're asked to find K if K is the X- Intercept.
At the x intercept... the corresponding y value is zero. This concept should be pretty clear.
Reason is...
At the Point where the line touches the x axis...If you trace the y value... It will be at point zero(0).
With this Knowledge
We're able to interprete that the points of K is
(x" , 0)
Where x" represents the x coordinate of K
So
J ( 0, - 10)
K ( x" , 0)
m= 2.
Applying the Gradient/Slope Formula
m = y₂ - y₁/x₂ - x₁
x₁ = 0 y₁ = -10
x₂ = x" y₂ = 0
Substituting
2 = 0 - ( -10)/ (x" - 0)
2 = 10/x"
x" = 10/2
x" = 5.
Coordinates of Point K is ( 5 , 0).

Total Time Taken = 16secs
10a). We're asked to calculate the rate of speed change for the first 5secs.
This is another way of saying "Calculate Acceleration" in the first 5sec of Motion.
Why?
Acceleration is the rate of change of speed or the rate at which speed changes.
acceleration = v - u/t
where v = Final Speed
u = initial Speed.
Looking at the graph
You see that
Initial speed(u) = 1m/s
Final Speed(v) = 9m/s
t = 5secs
Acceleration = 9 - 1/ 5
a = 8/5
a = 1.6m/s².✅
10b)
We're asked to calc "t" from the graph.
Given that the acceleration at "t" untill 16sec(end of motion) is 2m/s².
This simply means that Constant Acceleration was held from "t" to the end of the Motion.
Do not confuse Constant Acceleration for Constant Velocity.
At Constant Velocity... Acceleration is zero(0)
At Constant Acceleration...Velocity Changes Uniformly or at the same rate each second and this is what we're dealing with in this question.
Taking the same step as we used in calculating acceleration above
Given a= 2m/s²
a = v - u/∆t
Where ∆t means time change or difference.
From "t" to 16
The change in time is 16 - "t"
2 = 21 - 9/( 16 - t)
2 = 12/16-t
16-t = 12/2
16 - t = 6
t = 16 - 6
t = 10secs.✅

Round the answer to the nearest hundredth please ASAP!!!
Answer:
8.4
Perimeter=a+b+c
3.2+4.2+3.-2
= 8.4
The perimeter of the triangle will be 5 + √17.
What is the perimeter of the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. The sum of all the sides of the triangle will be known as the perimeter of the triangle.
A triangle DEF with vertices D (3,2), E (4,2), and F (3,-2).
Distance between DE will be
DE² = (4 - 3)² + (2 - 2)²
DE² = 1
DE = 1
Distance between EF will be
EF² = (3 - 4)² + (-2 - 2)²
EF² = 1 + 16
EF = √17
Distance between DF will be
DF² = (3 - 3)² + (-2 - 2)²
DF² = 16
DF = 4
Then the perimeter of the triangle will be
P = DE + EF + DF
P = 1 + √17 + 4
P = 5 + √17
The perimeter of the triangle will be 5 + √17.

Answer:
D because it costs less for 7 hours
Answer:
The company that would give you the best deal would be Company D.
Step-by-step explanation:
Company A:
First you set up as an equation.
y=25x+50
I used 25x because 25 represents the hourly rate and x represents the hour it increases.
y=25(7)+50
We have to substitute 7 in for x because it says "If you had planned for 7 hours".
Multiply 25 and 7. You should get 175.
y=175+50
Add 175 and 50. You should get 225.
y=225.
You do the same thing for the rest of the problems.
Company B:
y=30x+40
y=30(7)+40
y=210+40
y=250
Company C:
y=20x+60
y=20(7)+60
y=140+60
y=200
Company D:
y=5x+150
y=5(7)+150
y=35+150
y=180
The company that would give you the best deal would be Company D.

Bananas cost $3 a bunch and apples cost $0.50 each. If b represents the number of bunches of bananas and a represents the number of apples, which of the following expressions represents the total cost?
-
3b + 0.5a
3.50(b + a)
3.50ab
3.50b + a
3b + 0.5a
the variables b and a are unknown values that represent the number of bananas and apples to be bought. These are next to each of its prices for it to be multiplied once we know the variable.
The costs of the fruits are to be added and you will end up with the total cost of fruits.

Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept
We're given that the slope is 6. Plug this into [tex]y=mx+b[/tex] as m:

28. Ashton is hosting a banquet. He plans to spend $400, plus/minus $50, at a
cost of $25 per guest,
a. Find the maximum and minimum number of guests.
b. If there can be up to 7 guests per table, what is the minimum number of
tables Ashton should reserve so everyone has a seat?
Answer:
If he can spend $400 +- $50 ($350 or $450) the maximum number of guests at $25 each is 18 and the minimum is 14. If there can be up to 7 guests, he should prepare to have at least 3 tables to ensure everyone gets a seat if he goes with the $450 option.
Step-by-step explanation:
Please mark Brainliest if this helped :)
Division is one of the four fundamental arithmetic operations. The minimum number of tables Ashton should reserve so everyone has a seat is 2.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Ashton's budget is $400±50. Therefore, the maximum and the minimum budget that Ashton can spend on the banquet are,
Maximum budget = $400 + $50 = $450
Minimum budget = $400 - $50 = $350
A.) Now, the maximum guest will cost the maximum budget, therefore, we can write
Maximum guest = Maximum budget / Budget per guest
= $450 / $25
= 18
Minimum guest = Minimum budget / Budget per guest
= $350 / $25
= 14
B.) Since the minimum number of guests that can come to the banquet is 14, and only 7 people can seat at a table, therefore, the minimum number of tables Ashton should reserve so everyone has a seat is 2.

The three numbers are 29, 31, and 33.
Step-by-step explanation:
Let's imagine that the three consecutive odd integers are 2x−1, 2x+1, and 2x+3. And we are told the sum is 93 right? So, let's equal the three numbers to 93.
2x − 1 + 2x + 1 + 2x + 3 = 93
6x + 3 = 93
-3 -3
-----------------
6x = 90
/6 /6
----------------
x = 15
Now, plug in x into 2x−1, 2x+1, and 2x+3 to find the three numbers.
2x − 1 2x + 1 2x + 3
2(15) - 1 2(15) + 1 2(15) + 3

Now, in order to have the winning time, the last runner must have a time less than the fastest runner so far. So, the winning time is less than 7.09 seconds.
