Answer:
Deal A is best
Step-by-step explanation:
Given
Deal A:
3/4 lb for $2.50
Deal B:
2/10 lb for $5.25
Required
Which deal is the better
To do this, we simply calculate the lb/dollar ratio
i.e.
[tex]Ratio = \frac{Amount}{Size}[/tex]
For Deal A:
[tex]Ratio = \$2.50/\frac{3}{4}lb[/tex]
[tex]Ratio = \$2.50 * \frac{4}{3}lb[/tex]
[tex]Ratio = \frac{\$10}{3}lb[/tex]
[tex]Ratio = \$3.33/lb[/tex]
For Deal B:
[tex]Ratio = \$5.25/\frac{2}{10}lb[/tex]
[tex]Ratio = \$5.25 * \frac{10}{2}lb[/tex]
[tex]Ratio = \frac{52.5}{2}lb[/tex]
[tex]Ratio = \$26.25/lb[/tex]
The better deal is the least expensive:
Hence: Deal A is better

Answer:
22 2/3
Step-by-step explanation:
if it helps make it braintliest please
Answer:
22 10/15
Step-by-step explanation:
You would just convert the 2/3 to 15ths which would be 10/15ths. Then add all of the fractions to get 25/15 and that's equal to 1 10/15 and then add the 7, 5, and 9
Line segment YV of rectangle YVWX measures 24 units. Rectangle Y V W X is shown. A diagonal is drawn from point X to point V. The lengths of sides Y V and X W are 24 units. The angle of V X W is 30 degrees, the angle of X W V is 90 degrees, and the angle of X V W is 60 degrees. What is the length of line segment YX? 8 units 8 StartRoot 3 EndRoot units 12 units 12 StartRoot 3 EndRoot units
Answer:
The correct answer would be 8 root symbol 3
Step-by-step explanation:
because i chose it and got it right
The length of the line segment YX is [tex]8\sqrt{3}[/tex] if the line XW is of 24 units.
What is a trigonometric function?It is a ratio of sides of a right angled triangle.
How to use Trigonometric functions?It can be seen that the diagonal is making a right angle triangle XWV so
we will use the trigonometric function to determine the value of WV which will then be equal to XY because it is a rectangle.
tan(30)=VW/XW
1/[tex]\sqrt{3}[/tex]=VW/24
VW=24/[tex]\sqrt{3}[/tex]
VW=8[tex]\sqrt{3}[/tex] UNITS by multiplying and divide by root 3.
Hence the length of the side XY =8 root 3 units.

Hank likes to bake cake, and so he needs 3 eggs per cake. Write an expression to show how many eggs he will need if he bakes x cakes. Then, write an equation to determine how many eggs he will need to bake 11 cakes. Explain how you came up with the expression or equation, or how to use them to answer the problem
Answer:
3 eggs per cake = 33 eggs for 11 cakes
Step-by-step explanation:
if you multiply by 3 by 11 you get 33 so therefor for each one cake you need three eggs and for 11 cakes you will need 33 eggs

Two lines, A and B, are represented by the equations given below: Line A: y = x − 2 Line B: y = 3x + 4 Which of the following shows the solution to the system of equations and explains why? (−3, −5), because the point does not lie on any axis (−3, −5), because the point satisfies both equations (−4, −8), because the point satisfies one of the equations (−4, −8), because the point lies between the two axes
Answer:
The point (-3,-5) is the solution of the system because it satisfies both equations
Step-by-step explanation:
System of equations
A system of equations represents a situation where multiple conditions apply, and the possible solution to the system, if any, must satisfy all conditions, not just some of them.
We have the system of equations:
[tex]\left\{\begin{matrix}y=x-2\\ y=3x+4\end{matrix}\right.[/tex]
The solution of the system is an ordered pair (x,y) that satisfies both equations.
Test the point (-3,-5):
[tex]\left\{\begin{matrix}-5=-3-2=-5\\ -5=3*(-3)+4=-9+4=-5\end{matrix}\right.[/tex]
We can see both equalities are true, thus the point (-3,-5) is the solution of the system because it satisfies both equations

The volume of a circular cylinder is calculated using the formula = ^2*2ℎ. If the height ℎ is known to be equal to the diameter 2 and ℎ is measured at a percentage error of 2%, find the percentage error in calculating the volume of the cylinder.
Answer:
6%
Step-by-step explanation:
From the information given:
The height h is said to be equal to the diameter which is 2r
h = 2r
r = h/2
Recall that: The volume for calculating a circular cylinder is:
[tex]V = \pi r^2 h[/tex]
[tex]V = \pi (\dfrac{h}{2})^2 h[/tex]
[tex]V =\dfrac{\pi h^3}{2}[/tex]
[tex]\dfrac{dV}{dh} = \dfrac{3 \pi h^3}{4}[/tex]
Thus, the percentage error of the height can now be calculated as:
[tex]\dfrac{dh }{h} \times 100 = 2[/tex]
[tex]dh =\dfrac{h}{50}[/tex]
Now taking the differential of the volume, we have:
[tex]dV = \dfrac{dV}{dh}* dh[/tex]
[tex]dV = \dfrac{3 \pi h^2}{4}* \dfrac{h}{50}[/tex]
FInally, the %age change in the volume is calculated as follows:
[tex]\dfrac{dV}{V} = \dfrac{ \dfrac{3 \pi h^2}{4}* \dfrac{h}{50}}{\dfrac{\pi h^3}{2}}[/tex]
[tex]\dfrac{dV}{V} = \dfrac{3}{50} \times 100 \%[/tex]
[tex]\dfrac{dV}{V} =6 \%[/tex]
Thus; the percentage error in calculating the volume of the cylinder is 6%

∠ 3 = 40°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC for ∠ 1
∠ 1 = 180° - (58 + 90)° = 180° - 148° = 32°
∠ 2 = ∠ 1 = 32° ( vertical angles )
Thus
∠ 3 = 180° - (108 + 32)° = 180° - 140° = 40°

Fourteen minus the product of a number and 15
Answer:
"14-5x".
Step-by-step explanation:
Let the number be x. The given statement is "Fourteen minus the product of a number and 15".
The product of a number and 15 means 15x.
14 minus product of x and 15 = 14-15x
Hence, the given statement means "14-5x".

Veronica is ordering trophies for her school. Company P charges $3.50 for each trophy and a one-time engraving fee of $25. Company R charges $7.50 for each trophy and a one-time engraving fee of $17. Which inequality can be used to find x, the minimum number of trophies that can be ordered so that the total charge at Company P is less than the total charge at Company R?
Answer: Required inequality : [tex]3.50x+25<7.50x+17[/tex]
Solution: x<2.
Step-by-step explanation:
Let x = number of trophies.
Company P charges $3.50 for each trophy and a one-time engraving fee of $25.
Total charge for x trophies from Company P=[tex]3.50x+25[/tex]
Company R charges $7.50 for each trophy and a one-time engraving fee of $17.
Total charge for x trophies from Company R =[tex]7.50x+17[/tex]
When total charge at Company P is less than the total charge at Company R, then
[tex]3.50x+25<7.50x+17\\\\\Rightarrow\ 7.5x-3.5x<25-17\\\\\Rightarrow\ 4x<8\\\\\Rightarrow\ x<2[/tex]
Required inequality : [tex]3.50x+25<7.50x+17[/tex]
Solution: x<2.
Answer:

PLSSSSSSSS HELP! How do I find the domain AND range in the same graph??
Answer:
Step-by-step explanation:
Let's start with definitions.
Domain: Indicates the values that x can be, has a certain set
Range: Indicates the values that y can be, has a certain set
To find the domain of a graph, we want to see where all the x values fit. In the graph below's case, the domain would be -3<x≤1
To find the range, we need to see where all the y values fit. In the graph below's case, the range would be -4≤y<0.
Notice how some of them are < instead of ≤. This is because they have an open circle. When a point has an open circle, it means that point can't be included in the equation, hence the < instead of ≤

11. Members of the student council are conducting a fundraiser by selling school
calendars. After selling 80 calendars, they had a loss of $360. After selling
200 calendars, they had a profit of $600. Write an equation that describes the
relation between y, the profit or loss, and x, the number of calendars sold. How
much profit did they make from selling each calendar? How much would they
have lost if they had sold no calendars?
Answer:
See my explanations below please :)
Step-by-step explanation:
4. y-1 = 3(x-2)
5. y+5= -2(x+3)
6. y+11 = (3/4)(x-4)
7. y = (-1/6)(x-4)
8. y+2 = (5/8)(x+3)
9. y-1 = (3/8)(x+5)
10. Because after simplifying them, the final equations are the same
11. so we have (80,-360) and (200, 600)
m = (600-(-360)) / (200-80) = 960 / 120 =8
=> y+360 = 8(x-80)
Profit selling each = the slope m = $8
Working backwards, when they sold 80 calendars they still have a loss of $360, so the original loss (when x=0) = 80*8 + 360 = 640 + 360 = $1,000
