Answer:
D) (1,-5)
x = 1
y = -5
Step-by-step explanation:
y = 3x - 8
y = -9x + 4
substitute for y:
3x - 8 = -9x + 4
reduce:
12x = 12
x = 1
y = 3 - 8
y = -5
A SECRET CODE has 5 digits. Each digit is different. It is a multiple of 4 and 11. If the middle 3 digits are 926, in that order, what is the product of the first and last digits?
Answer:
The product of the first and last digits is 40.
Step-by-step explanation:
Multiple of 4 rule:
The last two digits must form a number that is divisible by 4.
Multiple of 11 rule:
We find the alternate sum of the digits, and it must be divisible by 11.
A SECRET CODE has 5 digits. The middle 3 digits are 926
So the code is
x926y
Divisible by 4:
This means that the 6y must be divisible by 4, which means that the possible values of y are 0, 4, 8.
Value of x when y = 0:
x9260
x - 9 + 2 - 6 + 0 = x - 13
It will be divisible by 11 when x - 13 = 22, that is, x = 9. However, the digit 9 is already used, which means that y = 0 is not a possible option.
Value of x when y = 4:
x9264
x - 9 + 2 - 6 + 4 = x - 9
It will be divisible by 11 when x - 9 = 0, that is, x = 9, which is not possible, as we saw above. Or
x - 9 = 11
x = 2
The digit 2 is also possible, so y cannot be 4.
Value of x when y = 8:
x9268
x - 9 + 2 - 6 + 8 = x - 5
x - 5 = 0 -> x = 5
So, the number is:
59268
What is the product of the first and last digits?
5*8 = 40
The product of the first and last digits is 40.

The list shows the numbers of each type of pie baked at a bakery today.
.
• 13 apple
•4 pecan
. 3 pumpkin
What percentage of the pies baked today were NOT apple?
A.70%
B.33%
C.66%
D 35 %
Answer: whats the answers
Step-by-step explanation
35% of the pies baked today were NOT apple.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is primarily used to compare and determine ratios and is represented by the symbol %.
Given:
The type of pie baked at a bakery today
13 apple
4 pecan
3 pumpkin
So, Total pie baked = 13 +4 + 3 = 20
So, percentage of the pies baked today were NOT apple
= 7 /20 x 100
= 7x 5
= 35 %
Hence, 35% of the pies baked today were NOT apple.

Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not?
A. No, there is no value in the domain that corresponds to more than one value of the range.
B. Yes, there is no value in the domain that corresponds to more than one value of the range.
C. Yes, the range value 3 corresponds to two domain values, 1 and 2.
D. No, the range value 3 corresponds to two domain values, 1 and 2.
Answer:
its a function so answer is b
Step-by-step explanation:
Answer:
B. Yes, there is no value in the domain that corresponds to more than one value of the range.
Step-by-step explanation:
Since there is one value of
y
for every value of
x
in ( 1 , 2 ) , ( 2 , 3 ) , ( 3 , 4 ) , ( 4 , 5 ) , ( 5 , 6 )
, this relation is a function.
The relation is a function.
Yes, there is no value in the domain that corresponds to more than one value of the range. Hope I helped
The correct option is
(2). Yes, there is no value in the domain that corresponds to more than one value of the range.
Step-by-step explanation: We are given to check whether the following relation is a function or not.
We know that,
the first element of each ordered pair in the relation above makes the domain and the second element of each ordered pair makes the range.
So, the domain will be
and the range will be
A RELATION will be a function if each value in the domain correspond to one and only one value in the range.
Since, in the set R, there is no value in the domain that corresponds to more than one value of the range, so
The given relation 'R' is a FUNCTION.
Thus, the correct option is
(2). Yes, there is no value in the domain that corresponds to more than one value of the range.
Nina buys a small rug in the shape of a kite. The width of the rug is half its height. What are the width and area of the rug? (height 31 inches width 9 inches)
Answer:
[tex]Width = 20\ in[/tex]
[tex]Area = 400\ in^2[/tex]
Step-by-step explanation:
Given
See attachment for kite dimension
Required
Determine the width and the area
From the attachment, the height of the kite is:
[tex]Height = 31\ in + 9\ in[/tex]
[tex]Height = 40\ in[/tex]
The width which is half the height is:
[tex]Width = \frac{1}{2} * Height[/tex]
[tex]Width = \frac{1}{2} * 40\ in[/tex]
[tex]Width = 20\ in[/tex]
The area is:
[tex]Area = \frac{Height * Width}{2}[/tex]
[tex]Area = \frac{40\ in * 20\ in}{2}[/tex]
[tex]Area = 40\ in * 10\ in[/tex]
[tex]Area = 400\ in^2[/tex]

Answer:
I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= [tex]\sqrt{1}[/tex]/2 = 1/2
Sing(45) = [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{2}[/tex]/2
Sin(60)=[tex]\sqrt{3}[/tex]/2 = [tex]\sqrt{3}[/tex]/2
Sin(90)=[tex]\sqrt{4}[/tex]/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = [tex]\sqrt{1}[/tex]/2 = 1/2
Cos(45) = [tex]\sqrt{2}[/tex]/2 = [tex]\sqrt{2}[/tex]/2
Cos(30) = [tex]\sqrt{3}[/tex]/2 = [tex]\sqrt{3}[/tex]/2
Cos(0) =[tex]\sqrt{4}[/tex]/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °
got it? :/

find the height of a trapezium if the sum of the lengths of the parallel sides is 39cm and whose area is 234cm²
Answer:
the answer according to my calculations will be 12
Step-by-step explanation:
the formula of area of trapezium is A=a+b÷2×h
and if we wanna solve for h
h=2 A÷ a+b
h=2 (234)÷39
after calculations...
h= 12
hope it helps:)
Answer:
h = 12 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h ( sum of parallel bases )
Here A = 234 and sum of bases = 39 , then
[tex]\frac{1}{2}[/tex] h × 39 = 234 ( divide both sides by 39 )
[tex]\frac{1}{2}[/tex] h = 6 ( multiply both sides by 2 to clear the fraction )
h = 12

Sam earns a 16% commission when he sells cars. Sam sells $506,325 worth of cars. What is his commission?
Answer:
Commission earned by Sam = $81012
Step-by-step explanation:
Earning of Sam for the sale of cars = 16% of total sales of the cars
Sam sells the car worth $506325
Therefore, commission on the total sales of the cars = Total sales × [tex]\frac{16}{100}[/tex]
= 506325 × 0.16
= $81012
Therefore, commission earned by Sam = $81012
