Answer:
The percentage decrease = 25%
Step-by-step explanation:
Given
Starting value = £800Final value = £600To determine
Percentage decreaseUsing the percentage decrease formula
% decrease = [Starting Value - Final Value] / [Starting Value] × 100
= [800 - 600] / [800] × 100
= [200] / [800] × 100
= 0.25 × 100
= 25%
Therefore, the percentage decrease = 25%

Step-by-step explanation:
The solution we're looking at here is a set of all the points between two parallel lines. Let's see what we can find out about those lines from the inequality, and use that the pick the correct option.
We can start by splitting the inequality at the top into two seperate inequalities:
[tex]7\leq y-3x<11\\y-3x\geq7\\y-3x<11[/tex]
From here, we can put each inequality into slope-intercept form:
[tex]y\geq3x+7\\y<3x+11[/tex]
Our slope for both lines is positive, so we can immediately eliminate B and D. A and C both display lines with slopes of 3 and y-intercepts of 7 and 11; the only difference is in which line is dashed and which line is solid.
As a reminder, a dashed line means that the line itself is not included in the solution, a solid line means that it is. Dotted lines always pop up when you see the symbols < and >, while solid lines pop up when you see ≤ and ≥.
[tex]y\geq3x+7[/tex] (Solid)
[tex]y<3x+11[/tex] (Dashed)
This matches up very nicely with the graph in A, our solution.

Which of the following equations, where d is distance in miles and t is time in hours, represents a speed that is less than that of the leatherback sea turtle?
Answer:
Options (A) and (B)
Step-by-step explanation:
Speed of the leatherback sea turtle = 21.92 miles per hour
If the sea turtle travels distance 'd' in 't' hours,
Speed [tex]=\frac{\text{Distance}}{\text{Time}}[/tex]
Speed that is less than 21.92 mph are 2.192 mph and 20 mph,
For speed = 20 mph
20 = [tex]\frac{d}{t}[/tex]
d = 20t
For speed = 2.192 mph
2.192 = [tex]\frac{d}{t}[/tex]
d = 2.192t
Therefore, Options (A) and (B) are the correct options.

The hull speed of a boat in knots per hour is determined by the length of the waterline. The waterline is the length of the boat that is actually in the water. This relationship can be modeled by the function h=1.34l where h is speed of the boat and L is the length of the waterline in feet. What is the length of the waterline if the hull speed is 4 knots
Answer:
The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.
Step-by-step explanation:
Let the function [tex]h = 1.34\cdot l[/tex], where [tex]l[/tex] is the length of the waterline, measured in feet and [tex]h[/tex] is the hull speed of the boat, measured in knots per hour. If we know that [tex]h = 4\,\frac{kt}{h}[/tex], then the length of the waterline is:
[tex]l = \frac{h}{1.34}[/tex]
[tex]l = \frac{4}{1.34}[/tex]
[tex]l = 2.985\, ft[/tex]
The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.

A store charges a restocking fee for any returned item based upon the item price. An item
priced at $200 has a fee of $12. Using a proportion, find the restocking fee for an item
priced at $180.
A. $18.00
B. $10.80
C. $13.33
D. $15.75
Answer:
B
Step-by-step explanation:
This is just a guesstimate because $200 is a $12 fee and all the other ones are high assuming the higher the item price is the high the fee will be, again this is a guesstimate!

Answer:
She left a $4.80 tip.
Answer:
Tip $4.80

Of the 150 students in 6th grade, 10% earned straight As last quarter. How many students earned straight As?
Answer: 15 students
Step-by-step explanation:
From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.
The number of students that earned straight As will be:
= 10% × 150
= 10/100 × 150
= 0.1 × 150
= 15 students

Solve: 5x-3+2x = 5x+3 show your work
Answer:
x = 3
Step-by-step explanation:
5x - 3 + 2x = 5x + 3
subtract 5x from both sides
5x - 5x - 3 + 2x = 5x - 5x + 3
-3 + 2x = 3
add 3 to both sides
-3 + 3 + 2x = 3 + 3
2x = 6
divide both sides by 2
2x/2 = 6/2
x = 6/2
x = 3
Answer:
x = 3
Step-by-step explanation:
5x - 3 + 2x = 5x + 3. that is
7x - 3 = 5x + 3 ( subtract 5x from both sides )
2x - 3 = 3 ( add 3 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
I need help with this if you can please send help my grade depends on it
Answer:
y= 77° x=103°
Step-by-step explanation:
x=103° Alternate angles are equal
y=77° angles on a straight line sum to 180° (180°-103°=77°)
Answer:
For x, we can justify that x=103° and for y, we can justify that it equals 77°.
Step-by-step explanation:
X°: VERTICAL ANGLE THEOREM, or if angles are opposite of each other and are formed by two intersecting straight lines, then they are congruent.
Thus, x°=103°
Y°: SUPPLEMENTARY ANGLE THEOREM, or if two angles are supplementary to the same angle, then the two angles are said to be congruent.
Thus, y°=77°

A family has two cars. During one particular week, the first car consumed 15 gallons of gas. The two cars Drove a combined total of 1475 miles and the sum of their fuel efficiency was 65 miles per gallon. What were the fuel efficiency of each of the cars that week?
Answer:
Car 1 : 40 miles per gallon
Car 2: 25 miles per gallon
Step-by-step explanation:
family has two cars. During one particular week, the first car consumed 15 gallons of gas. The second car consumed 25 gallons of gas. The two cars Drove a combined total of 1475 miles and the sum of their fuel efficiency was 65 miles per gallon. What were the fuel efficiency of each of the cars that week
Given that :
Fuel efficiency , car 1 = x
Fuel efficiency , car 2 = y
x + y = 65 - - (1)
15x + 35y = 1475 - - - (2)
x = 65 - y
15(65-y) + 35y
975 - 15y + 35y = 1475
20y = 14875 - 975
20y = 500
y = 25
Put y = 25 in (1)
x + y = 65
x + 25 = 65
x = 65 - 25
x = 40
