Answer:
11.5 hrs
Step-by-step explanation:
Divide 230 by 25. Then multiply your quotient by 1.25 which is 1 1/4 to get the number of hours. 230 divided by 25 is 9.2. 9.2 times 1.25 is 11.5

Write the standard form of the line that contains a slope of −1/2 and y-intercept of 1. Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
x + 2y = 4Step-by-step explanation:
Slope-intercept form:
y = mx + bSlope is m = -1/2 and y-intercept is b = 1
The function is:
y = -1/2x + 1Standard form is:
Ax + By = CConverting the function into standard form:
y = -1/2x + 2 ⇒ 2y = - x + 4 ⇒ x + 2y = 4Answer:
Step-by-step explanation:
Slope-intercept form of y = mx + b
Slope is m = -1/2 and y-intercept is b = 1
The function is y = -1/2x + 1
y+1/2x=1
(2y+1x)/2=1
2y+x=2
x+2y=2

Aakash can complete a work in 10 days. If he worked for 4 days and
the remaining work is done by Safal, how much work is done by Safal?
Step-by-step explanation:
Hey there!
According to the question;
Aakash can complete a work in 10 days.
That means;
In 10 days Aakash can complete 1 work.
In 1 day Aakash can complete (1/10) work.
In 4 days Aakash can complete (1/10)*4 part of work.
Therefore, in 4 days he can complete 2/5 part of work.
After 4 days Safal had to work.
So, work left was 1 - (2/5) {work left = whole work - done work}.
[tex]1 - \frac{2}{5} [/tex]
[tex] = \frac{3}{5} [/tex]
Therefore, the work Safal had to do was 3/5 part of work.

The area of a rectangle a=1(w) is represented by the expression 24x6y15. If the width of the rectangle is 2x3y9, what is the length of the rectangle
Answer:
Length of rectangle is: [tex]Length=12x^3y^6[/tex]
Step-by-step explanation:
The area of rectangle = [tex]24x^6y^{15}[/tex]
Width of rectangle = [tex]2x^3y^9[/tex]
We need to find length of rectangle
The formula used is: [tex]Area=Length\times Width[/tex]
Putting values and finding length
[tex]Area=Length\times Width\\24x^6y^{15}=Length\times 2x^3y^9\\Length=\frac{24x^6y^{15}}{2x^3y^9} \\Length=12x^{6-3}y^{15-9}\\Length=12x^3y^6[/tex]
So, Length of rectangle is: [tex]Length=12x^3y^6[/tex]

Find the measure of angle B
Answer:
Step-by-step explanation:
Use the Law of Cosines for this. If we want the measure of angle B, then the equation is set up like this:
[tex]b^2=a^2+c^2-2accosB[/tex]
Filling in:
[tex]9^2=14^2+6^2-2(14)(6)cosB[/tex] and simplifying a bit:
81 = 196 + 36 - 168cosB and a bit more:
81 = 232 - 168cosB and even more:
-151 = -168cosB and divide both sides by -168 to get
.9378881988 = cosB
Now use the 2nd button on your calculator along with the cos button to find the missing angle. Make sure your calculator is in degree mode first. Your angle should be 20.30012152

pages in that time. At what rate, in pages per hour, did Davida read?
Answer:
38 pages per hour
Step-by-step explanation:
Rate of reading = [tex]\frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}[/tex]
By substituting the given values in the question,
Total number of pages read by Davida = [tex]28\frac{1}{2}[/tex] = [tex]\frac{57}{2}[/tex]
Time taken by Davida = 45 minutes
Since, 1 minute = [tex]\frac{1}{60}[/tex] hours
Therefore, 45 minutes = [tex]\frac{45}{60}=\frac{3}{4}[/tex] hours
Rate of reading = [tex]\frac{\frac{57}{2}}{\frac{3}{4} }[/tex]
= [tex]\frac{57}{2}\times \frac{4}{3}[/tex]
= 38 pages per hour
Therefore, rate of reading by Davida is 38 pages per hour.

YALL HELP PLEASE THANK U
Answer:
I am not getting this question
Step-by-step explanation:
Given Vertex (5,4) and focus (8,4)
It can be easily noticed that focus and vertex lie on the same horizontal line y = 4
Obviously, the axis of symmetry is a horizontal line ( a line perpendicular to y-axis). Also, the focus lies to the right of the vertex so the parabola will open up rightward.
(y−k)^2=4a(x−h)
a=8-5=3 as y coordinates are the same.
Since the focus lies to the left of vertex, a = 3
(y−4)^2=4⋅3⋅(x−5)
(y−4)^2=12(x−5)
is the equation of the parabola.
Can someone help me find the missing side length!
Answer:
12
Step-by-step explanation
so what I did is I divided 15 by 5 to get 3 also 9 divided by 3 equals 3 to so you could of also done that.
then i multiplied to 4 x 3 to get the missing side length which equals 12
Answer:
the answer is 12
Step-by-step explanation:
to find the length we us this formula a²+b²=c²
a²+b²=c²
a²+(9)²=(15)²
a²+81=225
a²=225-81
a²=144
a=√144
a= 12 unit

You are eating a slice of pizza that has 391 calories in it. Each time you dip the pizza into ranch dressing, though, you add 7 calories to the total. If your meal wound up being 454 calories in total, how many times did you dip the pizza into ranch dressing? I don't get it
Answer:I think it is about 55 times
Step-by-step explanation:
Answer:
9 times
Step-by-step explanation:
The pizza has 391 calories in it, and everytime you dip it into ranch, you add 7 calories to the 391.
454(calories in total) - 391(calories in the pizza)= 63
63 ÷ 7(calories everytime you dip into ranch) = 9
blake is saving up on a new pair of headphones. He has $20 saved already, and he earns $10 for every lawn he mows. How many lawns will he have to mow to have at least $90 saved . What is the inequality and the solution?
Answer: 20× + 10 < 90
Step-by-step explanation:
Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7
What is inequality?Inequality is a mathematical statement that compares two values, expressing that one value is less than, greater than, less than or equal to, greater than or equal to, or not equal to another value.
Inequalities are commonly represented using symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to).
Let's assume Blake has to mow x lawns to have at least $90 saved.
Since he earns $10 for every lawn he mows, the amount he will earn by mowing x lawns is 10x.
Adding his initial savings of $20 to the amount he will earn from mowing lawns gives us the following inequality:
20 + 10x ≥ 90
Subtracting 20 from both sides:
10x ≥ 70
Dividing both sides by 10:
x ≥ 7
Therefore, Blake will have to mow at least 7 lawns to have at least $90 saved.
The inequality is: 20 + 10x ≥ 90
The solution is: x ≥ 7

Ms. Ruiz bought 12 packages of plates for the party. Each package contains 15 plates. She bought 10 packages of small plates and 2 packages of large plates. How many small plates did she buy? How many large plates did she buy? How many plates did she buy all together
Answer:
a) 150 plates
b) 30 plates
c) 180 plates
Step-by-step explanation:
Given that:
She bought twelve (12) packages of plates for the party in which each package contains 15 plates.
Out of the 12 packages;
10packages are small plates & 2 packages are large plates.
a) The number of small plates she bought = 10 × 15 = 150 plates
b) The number of large plates she bought = 2 × 15 = 30 plates
c) The total number of plates she bought all together is:
= number of small plates bought + = number of large plates bought
= (150 +30) plates
The total number of plates she bought all together = 180 plates
