300:51*100 =
(300*100):51 =
30000:51 = 588.24
Now we have: 300 is what percent of 51 = 588.24
Question: 300 is what percent of 51?
Percentage solution with steps:
Step 1: We make the assumption that 51 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=51$100%=51.
Step 4: In the same vein, $x\%=300$x%=300.
Step 5: This gives us a pair of simple equations:
$100\%=51(1)$100%=51(1).
$x\%=300(2)$x%=300(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{51}{300}$
100%
x%=
51
300
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{300}{51}$
x%
100%=
300
51
$\Rightarrow x=588.24\%$⇒x=588.24%
Therefore, 17% of 300 is 51
Answer:
Answer 17%
Step-by-step explanation:
Solution for 300 is what percent of 51:
300:51*100 =
(300*100):51 =
30000:51 = 588.24
588.24 as a percentage is 17%

A garden is in the shape of a rectangle 85 m by 50m.
Flowers are grown in 32% of the garden.
The rest of the garden is grass.
Work out the area of the garden that is grass.
Show your working out.
Answer:
2,890 meters^2 is grass
Step-by-step explanation:
First find the area of the garden
Area of a rectangle can be found using:
a=lw
a=85*50
a=4,250 meters^2
We know that 32% of the area is flowers, so we can multiply 32% and 4250
32%*4250
Convert 32% to a decimal by dividing by 100
32%/100=0.32
0.32*4250=1360
So, 1360 meters^2 is flowers.
The rest must be grass, so we can find the difference between the total area and the flowers
4250-1360=2890
So, 2,890 meters^2 is grass
Answer:
The answer to your question is 2890 m²
Step-by-step explanation:
Data
length = 85 m
width = 50 m
32% are flowers
Process
1.- Calculate the area of the garden
Area = length x width
-Substitution
Area = 85 x 50
= 4250 m²
2.- Calculate the area of the garden that are flowers
4250 ----------------- 100%
x ------------------ 32%
x = (32 x 4250) / 100
x = 136000/100
x = 1360 m² are flowers
3.- Calculate the area of the garden that is grass
Area of grass = 4250 - 1360
Area of grass = 2890 m²

After two numbers are removed from the list 9,13,15,17,19,23,31,49, the average and the median each increase by 2. What is the product of the two numbers that were removed?
Answer:
247
Step-by-step explanation:
Hello!
We can begin by finding the average and median before two numbers are removed.
(9 + 13 + 15 + 17 + 19 + 23 + 31 + 49) / 8 = 22
And the median!
(17 + 19)/ 2 = 18
Since we know that the average and median will increase by 2, we will have the median after removal as 20, and the average, 24.
For the average, we can see that the total must be 144, that's what 24 * 6 is.
19 must have been one of the numbers because (17 + 23) / 2 = 20.
That's 32 less than the original sum of 176.
So if one of the removed numbers is 19, the other must be 13.
13 * 19 = 247
Thus, the product of the removed numbers are [tex]\boxed{247}[/tex].

in a geometric sequence, the fourth term is 8 times the first term. the sum of the first 10 terms is 2557.5. find the 10th term of this sequence.
Answer: 1280
Step-by-step explanation:
The fourth term is 8 times the first term.
The fourth term = [tex]ar^3[/tex]
[tex]ar^{3} = 8a[/tex]
To find the common ratio:
∴ [tex]\frac{ar^3}{a} = \frac{8a}{a}\\[/tex]
∴ [tex]r^3 = 8\\r = 2\\[/tex]
Common ratio = 2
To find the nth number of terms = [tex]\frac{a(r^n -1)}{r-1\\}[/tex]
∴ [tex]\frac{a(2^{10} -1)}{2-1}[/tex]
∴ [tex]1023a\\[/tex]
The sum of 10 terms = 1023a
The sum of 10 terms = 2557.5
∵ 2557.5 = 1023a
∵ [tex]a = \frac{5}{2}[/tex]
To find the 10th term:
∴ [tex]ar^9\\[/tex]
∴ [tex]\frac{5}{2} *2^9[/tex]
⇒ 1280 ║ answer.
From the question given above, we were told that the fourth term is 8 times the first term. This can be written as:
T₄ = 8a
But
T₄ = ar³
a => is the first term
r => is the common ratio
Thus,
ar³ = 8a
Solving for the common ratio (r):
ar³ = 8a
Divide both side by a
r³ = 8
Take the cube root of both side
r = ³√8
r = 2
Thus, the common ratio (r) is 2
Next, we shall determine the first term (a). This can be obtained as follow:
Sum of 10th term (S₁₀) = 2557.5
Common ratio (r) = 2
Number of term (n) = 10
First term (a) =?Sₙ = a[rⁿ – 1] / r – 1
2557.5 = a[2¹⁰ – 1] / 2 – 1
2557.5 = a[1024 – 1]
2557.5 = 1023a
Divide both side by 1023
a = 2557.5 / 1023
a = 2.5
Thus, the first term is 2.5
Finally, we shall determine the 10th term of the sequence. This can be obtained as follow:
Common ratio (r) = 2
First term (a) = 2.5
10th term (T₁₀) =?T₁₀ = ar⁹
T₁₀ = 2.5 × 2⁹
T₁₀ = 2.5 × 512
T₁₀ = 1280
Therefore, the 10th term of the sequence is 1280

Two semicircles are placed in a rectangle. The width of the rectangle is 7 cm.
Find the area of the shaded region. Use the value 3.14 for pi , and do not round your answer.
Answer:
Total length of the rectangle = 14+14= 28cm
width= 7 cm
Area of the rectangle = 28×7cm²
= 196 cm²
Area of 2 semicircles = Area of 1 circle
= π(7)² = 3.14×49= 153.86cm²
Area of the shaded region = 196-153.86
= 42.14 cm²
Answer: 42.14 [tex]cm^2[/tex]
Step-by-step explanation:
Assuming that the width of the rectangle is 7 cm, the semi-circle's radius is also 7 cm.
Let's calculate the area of the two semi-circles, which in total makes a whole circle.
The formula for a circle is [tex]a=2\pi r^2[/tex]
Since r = 7, plug it in the formula:
[tex]a=2\pi (7)^2[/tex]
[tex]a=49\pi =153.86 cm^2[/tex]
Now, to figure out the length of the rectangle, look at the semi-circles. Their radius is 7 cm, so their diameter is 14 cm. We have two semi-circles with the diameter (14 cm), so we can say that the width is 28 cm.
Area of a rectangle: [tex]a=lw[/tex]
[tex]a=7*28=196cm^2[/tex]
To find the area of the shaded region, we subtract the area of the semi-circles to the rectangle, which should be:
[tex]196 - 153.86=42.14 cm^2[/tex]

The circle below has center K, and its radius is 3 yd. Given that m 2 LKM = 70°, find the length of the major arc LNM.
Give an exact answer in terms of 71, and be sure to include the correct unit in your answer.
Length of major arc LNM :
The length of the major arc LNM, in terms of pi, is 29π/6 yards.
The circle has a radius of 3 yards and the central angle m∠LKM is 70°. Since the question asks for the length of the major arc LNM, we first need to calculate the angle of the major arc. The angle of a full circle is 360°, so the angle of the major arc will be 360° - 70° = 290°.
To find the arc length, we use the formula for arc length (l) which is: l = rθ (in radians). We must convert the angle from degrees to radians by multiplying by π/180. So, 290° becomes (290π/180) radians.
Now, compute the length of the major arc LNM: l = 3 yd * (290π/180) = (870π/180) yd, which simplifies to: 29π/6 yd. Thus, the length of the major arc LNM, in terms of π, is 29π/6 yards.

7. What is the measure of ZE ?
Answer:
70 degrees
Step-by-step explanation:
The adjacent angles in a parallelogram are supplementary and add to 180 degrees
∠CDE+∠DEF=180
We know that ∠CDE is 110 degrees, so we can substitute that in
∠CDE+∠DEF=180
110+∠DEF=180
Subtract 110 from both sides
∠DEF= 70
So, ∠E is 70 degrees
Each lap Jeffery runs is 1 tenth of a mile. He wants to run 3 fifths
of a mile
How many laps does Jeffery need to run?
Answer:
6 laps
Step-by-step explanation:
Jeffery needs to run 3 laps.
Explanation:To find the number of laps that Jeffery needs to run, we can set up a proportion. We know that 1 lap is equal to 1 tenth of a mile, so we can set up the following proportion:
1 lap / 1 tenth mile = x laps / 3 fifths mile
Cross-multiplying and solving for x, we get:
x = (1 lap * 3 fifths mile) / (1 tenth mile)
x = 3 laps / 1 lap
x = 3
Therefore, Jeffery needs to run 3 laps.

Answer:
a) [tex]\sqrt{64+x^2}[/tex]
b) 15
Step-by-step explanation:
a) We know that AB = 8 and BC = x. We can use the Pythagorean Theorem, which states that for a right triangle with sides a, b, and c: [tex]a^2 +b^2=c^2[/tex] , where a and b are the shortest sides and c is the longest.
Here, AB = a = 8 and BC = b = x. So, AC = c. Then:
[tex]AB^2+BC^2=AC^2[/tex]
[tex]8^2+x^2=AC^2[/tex]
[tex]AC=\sqrt{64+x^2}[/tex]
b) We know that AC - AB = 9. Since AB = 8, then AC = 9 + 8 = 17. We also have the expression from above, so set them equal:
[tex]AC=\sqrt{64+x^2}=17[/tex]
[tex]64+x^2=289[/tex]
[tex]x^2=225[/tex]
x = 15
Hope this helps!
Answer:
sqrt(x^2 +64) = AC
x = 15
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 =c^2 a and b are the legs and c is the hypotenuse
We know the legs are x and 8
x^2 + 8^2 = AC^2
x^2 + 64= AC^2
Solving for AC
Take the square root of each side
sqrt(x^2 + 64) = sqrt(AC^2)
sqrt(x^2 +64) = AC
We are given AC - AB = 9
We know AB = 8
AC -8 =9
Add 8 to each side
AC -8+8 = 9+8
AC = 17
AC is the hypotenuse,
x^2 + 64= AC^2
x^2 +64 = 17^2
x^2 +64 = 289
Subtract 64 from each side
x^2 +64-64 = 289-64
x^2 =225
Take the square root
sqrt(x^2) = sqrt(225)
x =15

135g tinned fruit
2) 260 cm²
Step-by-step explanation:
1) 120/4 × 3
90g strawberry jelly
8/4 × 3
6 sponge fingers
420/4 × 3
315ml custard
180/4 × 3
135g tinned fruit
2) area = base × height
= 20 × 13
= 260 cm²
Answers and Step-by-step explanations:
1. Let's find the amount of each ingredient we need for 1 person, and then multiply that by 3 later.
strawberry jelly: we have 120 grams for 4 people, so for 1 person, we need 120/4 = 30 grams
sponge fingers: we have 8 of these for 4 people, so for 1 person, we need 8/4 = 2 sponge fingers
custard: we have 420 mL for 4 people, so for 1 person, we need 420/4 = 105 mL
tinned fruit: we have 180 grams for 4 people, so for 1 person, we need 180/4 = 45 grams
Now, multiply each of these by 3 to find the amount needed for 3 people:
strawberry jelly: 30 grams * 3 = 90 grams
sponge fingers: 2 sponge fingers * 3 = 6 sponge fingers
custard: 105 mL * 3 = 315 mL
tinned fruit: 45 grams * 3 = 135 grams
2. The area of a parallelogram is calculated by the formula: A = Bh, where B is the base length (usually a side length) and h is the height perpendicular to the base. Here, we see that have two potential base lengths: 20 and 15. However, looking at the height, it's only perpendicular to the base with length 20, so we know that B = 20 and h = 13.
Plugging these into the formula, we get: A = 20 * 13 = 260 cm squared.

A television program is 2 hours and 40 minutes long.
a)It starts at 22:45
at which time does it finish?
b)the program contains 8 ADs breaks,each of which lasts 3 min.
find the fraction of the 2 hours 40 min that is taken by ADs.
Give your answer in its simplest form.
Final answer:
The television program finishes at 00:25 after starting at 22:45 and running for 2 hours and 40 minutes. The fraction of the program's total time taken by 8 ad breaks, each lasting 3 minutes, is 3/20 of the total program time.
Explanation:
To calculate the finish time of the television program that starts at 22:45 and is 2 hours and 40 minutes long, we add the duration of the program to the start time. Firstly, we convert 2 hours and 40 minutes into minutes only to simplify addition. That is 160 minutes (120 minutes for 2 hours and 40 minutes for the remaining time). When we add 160 minutes to 22:45, we need to be careful due to the change of day at midnight.
Adding the minutes part first, 45 minutes + 40 minutes = 85 minutes. We subtract 60 minutes to account for one full hour giving us 25 minutes and add an hour to the hour part. 22:45 therefore becomes 23:25 with an additional 1 hour to be added.
We are left with 1 hour to add to 23:25, which simply gets us to 00:25, or 25 minutes past midnight. The television program finishes at 00:25.
Calculating the Fraction of Time Taken by Ads
The program contains 8 ad breaks, each of which lasts 3 minutes. The total time taken by the ads is 8 breaks × 3 minutes per break = 24 minutes of ads.
To find the fraction of time taken by the ads, we need the total duration in minutes, which is 2 hours and 40 minutes or 160 minutes. The fraction is therefore 24/160, which simplifies to 3/20 when we divide both the numerator and the denominator by 8.
Thus, the fraction of the 2 hours and 40 minutes that is taken by ads is 3/20.

Then the friend asked about the bears." there were a seventh as many bears as other animals", replied the trainer. Then the friend asked about the elephants. How should the trainer respond to the question?
Answer:
Step-by-step explanation:
Solution:-
- We will denote:
Number of Lions = x
Number of bears = y
Number of elephants = z
Any other animal = T
- Now we will mathematically each statement given by the trainer.
Statement 1:
"7 times as many lions than other animals (not lions)."
- There were 7 times as many lions than any other animals i.e ( bears and elephants). So we can express:
x = 7*( x + y + T) .... E 1
Statement 2:
"there were a seventh as many bears as other animals"
- There were 1/7 as many bears than any other animals i.e ( lions and elephants). So we can express:
y = (x+z+T) / 7 ... E2
- Now combine two decrypted mathematical expressions.
x + y + z = T
7T + T/7 + z = T

The complete question is
The dimensions of the square pyramid are
Base: 40 inches
Height: 12 inches
step 1
Find the volume of the square pyramid
The volume of the square Pyramid is given by the formula
[tex]V=\frac{1}{3}b^2h[/tex]
where
b is the length side of the square base
h is the height of the pyramid
we have
[tex]b=40\ in\\h=12\ in[/tex]
substitute
[tex]V=\frac{1}{3}(40)^2(12)[/tex]
[tex]V=6,400\ in^3[/tex]
step 2
Find the volume of sand
Multiply the number of bags of sand by the volume of each bag
so
[tex]3(1,200)=3,600\ in^3[/tex]
step 3
Compare the volume of the sand with the volume of the square pyramid
3,600 < 6,400
therefore
Kaytlyn has not enough sand to build the castle

The width of a rectangular rug is 6 feet if the perimeter is 24 feet what is the area of the rug?
Answer:
36 feet squared
Step-by-step explanation:
Finding the perimeter of an object is adding all of the sides together. If the width of the rug is 6 feet then we know that there are two sides that length. Add those together.
6 feet + 6 feet = 12 feet
You would subtract the number you get from the perimeter.
24 feet - 12 feet = 12 feet
And then divide the number by the number of sides left, 2, to get each of their lengths.
12 feet / 2 feet = 6 feet
To find the area of a rectangle you multiply length times width, which in this case both are 6 feets.
6 feet x 6 feet = 36 feet squared
