Answer:
21.25%
Step-by-step explanation:
To find the percent decrease, take the original amount and subtract the new amount
80-63 = 17
Divide this by the original amount
17/80 =.2125
Multiply by 100 to change to a percent
21.25%
If the length of SR is 4 meters and the length of ST is 8 meters , what is the length of PQ in meters
Answer:
the length of PQ is 8.9 m
Step-by-step explanation:
The computation of the length of PQ in meters is shown below:
Here we applied the Pythagoras theorem
c² = a² + b²
= 4² + 8²
= 16 + 64
= 80
Now square root to the both sides
c = √80
= 8.94427191
= 8.9 m
Hence, the length of PQ is 8.9 m

what is the slope of this line? I'm not sure if I'm doing it right. But I did it like this:
change in y/change in x
-4-4/-4-1
-8/-5
should i simplify it? or keep it a fraction?
Looks like the rise(y) is 2.5 and the run(x) is 1.5. ur going from neagitive to poitive or viseversa so 2.5/1.5. usally use two points on the line. i used (-1.5,0) and (0,2.5) to get 2.5/1.5

What is the total surface area??
Answer:
790 units^2
Step-by-step explanation:
Take the area of each side and add them all up. Remember each side is there twice.
Formula: SA = 2(15*5 + 15*16 + 5*16)
SA = 2(75 + 240 + 80)
SA = 2(395)
SA = 790
The oblique prism has a rectangular base with a width of 10 units and a length of 13 units. An oblique prism with a rectangular base is shown. The rectangular base has a width of 10 units and a length of 13 units. The distance between the top and the bottom base is 17 units. The top base extends 8 units to the right of the bottom base. The top base extends 8 units to the right of the bottom base. What is the volume of the prism? 1,040 cubic units 1,360 cubic units 1,950 cubic units 2,210 cubic units
Answer:
1,950 cubic units
Step-by-step explanation:
The computation of the volume of the prism is shown below:
Area of the rectangle = length × breadth
= 10 units × 13 units
= 130 units^2
Now the volume of the prism is
= Base × height
= 130 units × √(17^2 - 8^2)
= 130 units × 15 units
= 1,950 cubic units
Answer:
1,950 Cubic Units

14)
Sub Answer
acer
Answer:
£290.70
Step-by-step explanation:
Number of notes of $50 = 5
Total value = 50 × 5 = $250
Number of notes of $20 = 2
Total value = 20 × 2 = $40
Number of notes of $10 = 7
Total value = 10 × 7 = $70
Number of notes of $5 = 3
Total value = 5 × 3 = $15
Total value of all notes with John = 250 + 40 + 70 + 15
= $375
Since, $1.29 = £1
Therefore, $1 = £[tex]\frac{1}{1.29}[/tex]
Therefore, $375 = £ [tex]\frac{375}{1.29}[/tex]
= £290.70

Answer:
[tex]\boxed {\boxed {\sf x \approx 23.49 \ cm }}[/tex]
Step-by-step explanation:
This is a right triangle (the small square in the corner signifies a 90 degree angle), so Pythagorean Theorem can be used.
[tex]a^{2} + b^{2} =c^{2}[/tex]
where a and b are the legs of the triangle and c is the hypotenuse. In this triangle, 17 and x are the legs because they form the right angle. 29 in the hypotenuse because it is opposite the right angle.
[tex]a= 17 \\b=x \\c= 29[/tex]
[tex]17^{2} + x^{2} =29^{2}[/tex]
Solve the exponents.
17²=17*17=28929²= 29*29=841[tex]289+x^{2} =841[/tex]
289 is being added to x and the inverse is subtraction. Subtract 289 from both sides to isolate the variable.
[tex]289-289+ x^{2} =841-289\\x^{2} =552[/tex]
x is being squared and the inverse is a square root. Take the square root of both sides of the equation.
[tex]\sqrt {x^{2} }=\sqrt {552}[/tex]
[tex]x=23.4946802489[/tex]
Let's round to the nearest hundredth. The 4 in the thousandth place tells us to leave the 9.
[tex]x \approx 23.49[/tex]
x is approximately 23.49 centimeters.

Answer:
Jessica's trains travels at a faster speed
Step-by-step explanation:
From the question,
Using the graph,
The total distance distance traveled by Khalid after 2 hours is
d = 280 mi.
S = d/t....................... Equation 1
Where S = Khalid's speed, d = Khalid's distance, t = time.
S = 280/2
S = 140 mph.
From the euqation,
The total distance traveled by Jessica after 2 hours is
y = 150×2
y = 300 mi.
Also Using
S' = d'/t
Where S' = Jessica's speed, d' = Jessica's distance
S' = 300/2
S' = 150 mph.
From the above, Jessica's trains travels at a faster speed

Pls help! I dont know what to put im horrible at patterns
Answer:
divide by 4, 12, 21
Step-by-step explanation:
first, look at 20, and 5. How do you get there?
well, there are 2 possible ways.
20/4=5, or 20-15=5
we take it into the next pattern to get
44/4=11, and 44-15=29.
so now we know that the rule is to divide by 4
____________________________________________
36/4 = 12
84/4=21
Answer:
1. 36 / 4 = 9
2. 84 / 4 = 21
Rule: The input divided by 4. (I / 4 = O)
Step by Step explanation:
Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.

What is the surface area of the cone?
14 in²
43.96 in²
50.24 in²
56.52 in²
The surface area of the cone is 56.52 in².
What is Surface Area?An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.
As per the given diagram:
slant height of the cone (l) = 7 inch
radius of the cone (r) = 2 inch
For the surface area of the cone:
= πr(l+r)
= (22/7) × 2 × (7 + 2)
= (396/7)
= 56.52 in²
Hence, the surface area of the cone is 56.52 in²
