Answer: First one is 12
Second is 6:8
Third is 3:5
Fourth is 240
Last one is 3:5
Step-by-step explanation:
If you get 2 loaves of bread for 3 cups of raisins and you need 8 loaves then you do 3x4 to get 12
Do 3x2=6 then 4x2=8 so 6:8
Do 3x4=12 and 5x4=20 so 3:5
12/4 is 3 so we know that we divide by 3 720/3 is 240

11) Find the length of XZ.If WY = 15x -2 and XZ = 9x + 10,TVZY
Answers
Answer:
XZ = 28
Explanation:
The trapezoid is isosceles because it has two equal sides WZ and XY.
The diagonals of isosceles trapezoids have the same length. So, WY is equal to XZ and we can write the following equation:
WY = XZ
15x - 2 = 9x + 10
Then, solving for x, we get:
15x - 2 = 9x + 10
15x - 2 + 2 = 9x + 10 + 2
15x = 9x + 12
15x - 9x = 9x + 12 - 9x
6x = 12
6x/6 = 12/6
x = 2
Therefore, the value of XZ is equal to:
XZ = 9x + 10
XZ = 9(2) + 10
XZ = 18 + 10
XZ = 28
So, the answer is XZ = 28
An aerospace company has submitted bids on two separate federal government defense contracts. The company president believes that there is a 45% probability of winning the first contract. If they win the first contract, the probability of winning the second is 75%. However, if they lose the first contract, the president thinks that the probability of winning the second contract decreases to 52%.
Answers
1. The probability that they win both contract will be 23.4%.
How to calculate the probability?It should be noted that probability simply means the likelihood that an event will occur.
The probability of winning the contract will be:
= Probability of A winning × Probability of B winning
= 45% × 52%
= 0.45 × 0.52
= 0.234
= 23.4%
The probability is 23.4%

Write the equation of the line with the points (0, 2) and (4, 10) in standard form.
Answers
By definition, the of a line written in Standard form is:
[tex]Ax+By=C[/tex]Where "A", "B" and "C" are Integers ("A" is positive).
The Slope-Intercept form of the equation of a line is:
[tex]y=mx+b[/tex]Where "m" is the slope and "b" is the y-intercept.
You know that this line passes through these points:
[tex](0,2);(4,10)[/tex]By definition, the value of "x" is zero when the line intersects the y-axis. Then, you can identify that, in this case:
[tex]b=2[/tex]Now you can substitute the value of "b" and the coordinates of the second point into the following equation and solve for "m":
[tex]y=mx+b[/tex]Then, the slope of the line is:
[tex]\begin{gathered} 10=m(4)+2 \\ 10-2=4m \\ 8=4m \\ \\ \frac{8}{4}=m \\ \\ m=2 \end{gathered}[/tex]Therefore, the equation of this line in Slope-Intercept form is:
[tex]y=2x+2[/tex]To write it in Standard form, you can follow these steps:
- Subtract 2 from both sides of the equation:
[tex]\begin{gathered} y-(2)=2x+2-(2) \\ y-2=2x \\ \end{gathered}[/tex]- Subtract "y" from both sides of the equation:
[tex]\begin{gathered} y-2-(y)=2x-(y) \\ -2=2x-y \\ 2x-y=-2 \end{gathered}[/tex]The answer is:
[tex]2x-y=-2[/tex]Answer:
2x-y =-2
Step-by-step explanation:
To find the equation of the line in standard form, first, we need to find the slope
m = ( y2-y1)/(x2-x1)
m = (10-2)/(4-0)
= 8/4 = 2
Then we can use the slope intercept form
y = mx+b where m is the slope and y is the y-intercept
y = 2x +b
Using the y-intercept ( 0,2)
y = 2x +2
The standard form is Ax +By =C where A is a positive integer and B is an integer
Subtract 2x from each side
-2x +y = 2
Multiply each side by -1
2x-y =-2

Lashonda, Josh, and Brian sent a total of 90 text messages during the weekend, Lashonda sent 10 more messages than Josh. Brian sent 2 times as manymessages as Josh. How many messages did they each send?Number of text messages Lashonda sent:Number of text messages Josh sent:Number of text messages Brian sent:
Answers
Defining:
Number of messages of Lashonda = L
Number of messages of Josh = J
Number of messages of Brian = B
We know that:
L+J+B=90 (Equation 1)
We also know:
L = J+10 (Equation 2)
B=2J (Equation 3)
Now, we can substitue the values for L and B in the first equation
L+J+B=90
J+10 + J + 2J = 90
4J=90-10
4J=80
J=80/4
J=20
Since you found how many messages Josh sent, we can return to Equation 2 and 3:
L = J+10
L = 20 + 10
L = 30
B=2J
B=2*20
B=40
ANSWER:
Number of text messages Lashonda sent: 30

How to determine the solution to the word problem?The statements in the question are:
Two numbers add to 39. One number is 9 less than 7 times the other.Let the numbers in the expressions be x and y
So, we have
x + y = 39
x = 7y - 9
Substitute x = 7y - 9 in the equation x + y = 39
So, we have
7y - 9 + y = 39
Evaluate the like terms
8y = 48
Divide both sides by y
y = 6
Substitute y = 6 in x + y = 39
x + 6 = 39
Evaluate the like terms
So, we have
x = 33
Hence, the numbers are 33 and 6

Answers
First we have to take a look at the expression f(x + 1). This represents an horizontal translation. So this is the first transformation:
1. Horizontal translation
Now we can see that we have to multiply f(x + 1) by -1. This represents a reflexion on the y-axis
2. Reflection on y-axis
Finally we can see that -f(x + 1) is added by 3 units. This represents a vertical translation:
3. Vertical translation
Answer:
1. Horizontal translation
2. Reflection on y-axis
3. Vertical translation
Now let's see the final function:
f(x) = 2x - 5
f(x+1) = 2(x + 1) - 5
f(x+1) = 2x + 2 - 5
f(x+1) = 2x - 3
g(x) = -2x + 3 + 3
g(x) = -2x + 6
So let's plot f and g on the same reference system:

Marco bought 12 roses for $48. Each rose was originally $4 before the discount, and Super Saver Get $2 off each rose when you buy 12 or more roses each rose is $6.
How to calculate discount?The discount formula is as follows: Discount = Marked Price - Selling Price. OR. Formula for Discount Percentage = Marked Price Discount Rate A 10% discount can be calculated in two steps: Step 1 is to convert your percentage to a decimal using the formula 10 / 100 = 0.1. As a decimal, 10% equals 0.1. Step 2 is to multiply your original price by the decimal you chose. The sweaters were originally priced at $80. The store would like to offer a 15% discount on the sweaters. The company converts 15% to the decimal 0.15 to calculate the discount. The result is a figure of $12 after multiplying 0.15 by the original price of $80.Therefore,
Marco bought 12 roses for $48. Each rose was originally $4 before the discount.

A company has determined that the demand function for a certain couch is given by

Determine how many couches should be manufactured and sold in order to maximize profit. Start by finding functions to represent the revenue and the total cost, then find a function for profit
Answers
The number of couches manufactured and sold in order to maximise the profit is 1560.
The demand function will be
p = 2700 - 0.75x
Here p = price per couch and x = number of couch
Total Fixed cost = $760000
Variable cost per couch = $360
Total cost = Fixed cost + variable cost
T(x) = 760000 + 360x
Revenue function will be
R(x) = Px
(2700 - 0.75x)x
2700x - 0.75x²
Since profit function = Pr(x)
Pr(x) = R(x) - T(x)
= 2700x - 0.75x² -760000 -360x
- 0.75x² + 2700x - 360x - 760000
For maximum profit
[tex]\frac{d}{dx}(Pr(x)) = 0[/tex]
[tex]\frac{d}{dx}[-0.75x^{2} + 2340x -760000 ] = 0[/tex]
-1.5x + 2340 = 0
x = 2340/1.5
x = 1560
The couches sold for maximum profit = 1560
Therefore, the number of couches manufactured and sold in order to maximise the profit is 1560.

Answers
The length of the radius of the circle is √61.
Here there are two endpoints of the circle (-7,-4) and (3,8)
To find the distance between the two points we have a formula:
Distance = [tex]\sqrt{(x_{2} -x_{1} ^{2} + (y_{2} - y_{1})^{2} }[/tex]
So here we have
([tex]x_{1} , y_{1}[/tex]) = (-7, -4)
([tex]x_{2} , y_{2}[/tex]) = ( 3,8)
Putting the value we have,
=[tex]\sqrt{(3-(-4))^{2} + (8-(-7))^{2} }[/tex]
=[tex]\sqrt{10^{2} + 12^{2} }[/tex]
=√244
=2√61
The diameter is 2√61
radius = diameter/2
= 2√61/2
= √61
Therefore the length of the radius of a circle is √61.

x - 10
The function of f^(-1)(x) = 3(x + 17) / 2 is:
(2x / 3) - 17
Hence, These are the Match of one-to-one functions with their inverse functions.
