Step-by-step explanation:
Number of pounds = 8pounds
Cost of pasta = $12
Now;
Unknown:
cost per pound of pasta
Solution:

Change 10/25 to a decimal
Answer:
0.4
Step-by-step explanation:
→ Convert fraction to a denominator of 100
10 / 25 ⇔ 40 / 100
Answer:
0.4
Step-by-step explanation:
An easy way to do this is to get the fraction over 100
So, multiply the fraction by 4 (because 25*4=100)
then you get 40/100 which is 0.4 in decimal form
4x + 5y = -30
slope intercept form
Slope intercept form of the equation 4x + 5y = - 30 is written as,
⇒ y = - 4/5x - 6
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
We have to given that;
The equation is,
⇒ 4x + 5y = - 30
Now, We know that;
Slope intercept form of the equation is,
⇒ y = mx + c
Here, The equation is,
⇒ 4x + 5y = - 30
Subtract 4x both side,
⇒ 4x + 5y - 4x = - 30 - 4x
⇒ 5y = - 4x - 30
Divide by 5 both side, we get;
⇒ y = - 4/5x - 6
Hence, The Slope intercept form of the equation is,
⇒ y = - 4/5x - 6

The hours a week people spend answering and sending emails is normally distributed with a standard deviation of Ï = 150 minutes. How large of a sample size would you need to estimate the mean number of minutes people spend answering and sending emails with an error of 1 minutes with 99% confidence? What would be the practical problem with attempting to find this confidence interval?
Answer:
sample size n would be 149305 large
Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval
Step-by-step explanation:
Given that;
standard deviation α = 150 min
confidence interval = 99%
since; p( -2.576 < z < 2.576) = 0.99
so z-value for 99% CI is 2.576
E = 1 minutes
Therefore
n = [(z × α) / E ]²
so we substitute
n = [(2.576 × 150) / 1 ]²
n = [ 386.4 ]²
n = 149304.96 ≈ 149305
Therefore sample size would be 149305 large
Value of n is too high, that would be the practical problem with attempting to find this confidence interval

Use the diagram to find the length. PB is the perpendicular bisector of AC. QC is the perpendicular bisector of BD. AB = BC = CD.
Given BD = 16 and PC = 10, find PB.
PB =
Answer:
6 units
Step-by-step explanation:
BC = BD/2 = 8
PB² + 8² = 10²
PB² = 100 - 64 = 36 ⇒ PB = 6 units
The length of PB = 6 units
Here, PB is the perpendicular bisector of AC and QC is the perpendicular bisector of BD.
AB = BC = CD
Given that BD = 16 and PC = 10
What is Pythagoras theorem?
Pythagoras theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square of the hypotenuse.
Here, BD = 16 and AB = BC = CD
⇒ BC = BD/2 = 16/2 = 8
And, PC = 10
Now using Pythagoras theorem:
[tex]PC^{2} =PB^{2} + BC^{2}[/tex]
[tex]10^{2} =PB^{2} + 8^{2}[/tex]
[tex]PB^{2} + 64 = 100\\PB^{2} = 100 - 64\\PB^{2} = 36\\PB = \sqrt{36}\\PB = 6[/tex]
Hence the length of PB = 6 Units

how many times greateri is the value of the digit 9 in 90,000 than the value of the digit 9 in 9,000
Answer:
It is 10 times greater.
Step-by-step explanation:
The place value of 9 in 90,000 is in the 10,000th place.
The place value of 9 in 9,000 is in the 1,000th place.
10,000 divided by 1,000 = 10.
In conclusion, the place value of 9 in 90,000 is 10 times greater than the palce value of 9 in 9,000.
Mr. Barnes hired a plumber to fix a leak. The total cost, in dollars, that the plumber charges for a job can be modeled by the function
p() = 45 +35x, where x represents the time, in hours, that the plumber used to complete the job.
Mr. Barnes budgeted $220 to pay the plumber for the job.
After how many hours will the cost of the job exceed Mr. Barnes's budget?
Answer:
After 5 hours
Step-by-step explanation:
Given
[tex]p(x) = 45 + 35x[/tex]
Required
Determine what time the budget would exceed $220
To do this, we simply substitute 220 for p(x)
[tex]220 = 45 + 35x[/tex]
[tex]220 - 45 = 35x[/tex]
[tex]175= 35x[/tex]
Solve for x
[tex]x = 175/35[/tex]
[tex]x = 5[/tex]
So, Mr. Barnes would exceed his budget after 5 hours

Arianna is deciding between two different movie streaming sites to subscribe to. Plan A costs $32 per month plus $1 per movie watched. Plan B costs $7 per month plus $2 per movie watched. Let AA represent the monthly cost of Plan A if Arianna watches xx per month, and let BB represent the monthly cost of Plan B if Arianna watches xx movies per month. Write an equation for each situation, in terms of x,x, and determine the number of monthly movies watched, x,x, that would make the two plans have an equal monthly cost.
Answer:
25 movies
Step-by-step explanation:
First, create the monthly costs for both plans:
Plan A:
A = x + 32
Plan B:
B = 2x + 7
Set these two expressions equal to each other, and solve for x:
x + 32 = 2x + 7
32 = x + 7
25 = x
So, the two plans will have an equal monthly cost after 25 movies.
Answer:
25 movies watched
Step-by-step explanation:
Where x is movies watched
AA = 1x + 32
BB = 2x + 7
Each square and figure DNE has a side length of one unit compare the area of the two figures which figure has more area how much more explain or show your reasoning
Answer:
✅Figure E has more area
✅Figure E has 5.14 units² much more than Figure D.
Step-by-step explanation:
The logic to solving this kind of problem is to decompose and each of the figure to find out how many squares and circles are there in each figure, them calculate the area of each figure using the formula for area of square and area of a circle.
✍️Figure D:
Figure D is composed of 2 squares and 4 semicircles (2 full circles).
Since side length of 1 square = 1 unit, therefore, radius of the semi-circle/circle = 1 unit.
Area of the 2 squares = 2(s²) = 2(1²) = 2 unit²
Area of the 2 full circles = 2(πr²) = 2(3.14*1²) = 6.28 unit²
Area of Figure D = 2 + 6.28 = 8.28 unit²
✍️Figure E:
Figure E is composed of 4 squares and 6 quarter circles (3 full circles).
Area of the 4 squares = 4(s²) = 4(1²) = 4 unit²
Area of the 3 full circles = 3(πr²) = 3(3.14*1²) = 9.42 units²
Area of figure E = 4 + 9.42 = 13.42 unit²
✅Therefore, we can conclude that Figure E has more area.
✅Figure E has 5.14 unit² more area than Figure D (13.42 - 8.28 = 5.14).
