1/5 of a number is 100 .How much is 2/3 of the number
Answer:
66?
Step-by-step explanation:
Answer:
333.33
Step-by-step explanation:
If we know that 1/5 of an unkown number is 100, then to find then original number we can multiply 100 by 5. This leaves us with 500, the original number. Now, we can multiply 500 by 2/3 to find our final answer.

18 bracelets in 3 hours
Answer:
= 6 items per hour
Explanation:
This is a fraction equal to 18 items ÷ 3 hours
We want a unit rate where 1 is in the denominator, so we divide top and bottom by 3
18 items ÷ 3
3 hours ÷ 3
= 6 items/1 hour
= 6 items/hour
= 6 items per hour

Step-by-step explanation:
to find the volume of a rectangular prism, Volume = length x height x width
Volume is 45 units (given)
length is 5 units (given)
45 = 5 x w x l
45 / 5 = w x l
9 = w x l
only 3 x 3 = 9 works with these numbers
45 = 5 x 3 x 3
Marco invested $3000 into a fund that is expected to grow by 4.23% per year. How long will it take the fund to be worth $6000?
[tex]6000 = 3000(1+0.0424)^{t}[/tex]
t = 16.73 years
Step-by-step explanation:This can be solved using the "exponential growth" formula.
Steps:
A = Final Amount
S = Starting Value
r = rate
c = times in a year ( c = 1 in this equation which is why it's not shown in the actual equation )
1. [tex]A=S(1+\frac{r}{c})^{ct}[/tex] → cancel out S → [tex]\frac{A}{S} = \frac{S(1+\frac{r}{c})^{ct} }{S}[/tex]
2. [tex]\frac{A}{S} = {(1+\frac{r}{c})^{ct} }[/tex] → sperate ct from equation by logging both sides (logging a value with an exponent brings the exponent in front of log) → [tex]log(\frac{A}{S}) = ctlog(1+\frac{r}{c})[/tex]
3. [tex]log(\frac{A}{S}) = ctlog(1+\frac{r}{c})[/tex] → transfer right side log to left side along with the c value to only have t remaining → [tex]\frac{log(\frac{A}{S})}{clog(1+\frac{r}{c})} = \frac{ctlog(1+\frac{r}{c})}{clog(1+\frac{r}{c})}[/tex]
4. Solve for answer: [tex]\frac{log(\frac{A}{S})}{clog(1+\frac{r}{c})} = t[/tex]

The total surface area of the cone is 542.592 square mm
Total surface area of a coneThe formula for calculating the total surface area of a cone is expressed as:
TSA = πr(r + l)
where
r is the radius of the cone
l is the slant of the cone
Given the following parameter
l = 13.6mm
r = 8mm
Substitute
TSA = π(8)(8+13.6)
TSA = 3.14(8)(21.6)
TSA = 542.592 square mm

Round and enter to one decimal place only.
The accounts receivable turnover ratio for the year ended January 31, 2021, for Somerset Corporation is 11.3 times.
What is the accounts receivable turnover ratio?The accounts receivable turnover ratio is a financial measurement of the effectiveness of a company to extend credits and collect debts.
The ratio, which shows the number of times per period that Somerset Corporation can collect its credit sales, can be computed as net credit sales divided by average accounts receivable.
Data and Calculations:Sales on account = $650,000
Accounts receivable balances:
February 1, 2020 = $60,000
January 31, 2021 = $55,000
Average receivable = $57,500 ($60,000 + $55,000)/2
Accounts receivable turnover ratio = Net credit sales/Average receivables
= 11.3 x ($650,000/$57,500)
Thus, the accounts receivable turnover ratio for the year ended January 31, 2021, for Somerset Corporation is 11.3 times.

The length, breadth and height of a cuboid bear the ratio 5:3:2 . If it's total surface area is 279 cm²,find it's volume.
Answer:
810 cm^3
Step-by-step explanation:
Since,the l(length) b(breadth) & h(height) of the cuboid bear the ratio 5 : 3 : 2 ,we could assume it as:
l = 5zb = 3zh = 2zWe know that,
Cuboid ( total surface area)= 2lb+2lh+2hb cubic unitsSo substitute the dimensions we assumed:
We could write it as;[tex] \rm \: Total \; Surface\; area \: of \: the \; cuboid = 2(5z \times 3z + 3z \times 2z + 2z \times 5z[/tex]
[tex] \implies \rm \: 279 = 31 {z}^{2} [/tex]
Find z[tex] \rm \implies {z}^{2} = \cfrac{279}{31} [/tex]
[tex] \rm \implies {z}^{2} = 9[/tex]
[tex] \implies \rm \: z = \sqrt{9} [/tex]
[tex] \rm \implies \: z = \sqrt{3 \times 3} = 3[/tex]
Hence, according to the formula,
Cuboid V = lbhWe got the dimensions of the cuboid, i.e.
Then, solve.
Cuboid V = lbh15 cm * 9 cm * 6 cm810 cm^3Hence,the volume of the cuboid will be 810 cm^3
Two angles of a triangle are the same size. The third angle is 12 degrees smaller than the first angle. Find the measure the angles
Answer:12, 84 and 84
Step-by-step explanation:
since we know 3 angles of a triangle = 180 degrees
1 angle = 12 degrees
12 + x + x = 180
12 + 2x = 180
2x= 180 - 12
2x = 168
x = 168/2
x = 84 degrees
Hope it helps! Mark it as Braniest
Answer:
64° , 64° , 52°
Step-by-step explanation:
Angle sum property of triangle:The two angles that are same be 'x'
Third angle = x - 12
Sum of all angles of triangle = 180
x + x + x -12 = 180
3x - 12 = 180
3x = 180 + 12
3x = 192
x = 192/3
x = 64
x - 12 = 64 - 12
= 52

⚫️n = 1c
⚫️n = 1+c
⚫️c = 1n
⚫️c = 1 + n
Answer:
C=1n
Step-by-step explanation:
So first you look for keywords, the most noticeable one is "total cost." C will be at the end of the equation.
C= ? + ?
Then, each hot dog costs $1 which means no matter how many hot dogs there will be, it will be multiplied by the cost. So, the answer is:
c=1n

identify a major league ballpark in which the distance from home plate to the center field
fence and the height of the center field fence require that a ball hit 2 ft above the ground will
necessitate an angle of elevation less than 0.86 to just clear the center field fence. The
ballpark you will identify today is known as "Comersia Park "aka the home of the Detroit
tigers. The distance between the Homeplate to the center field fence is 420 ft. however the
center field fence height is 9ft. make sure to find out the elevation and velocity?
Answer:
first off the park you've listed is no match for the fact its more then 0.86.
Step-by-step explanation:
[tex]tan^{-1} (\frac{7}{420} )\\\\= arctan (\frac{7}{420} )\\\\= arctan (\frac{1}{60} )\\= 0.95[/tex]
so basically it equals 0.95°
which basically means 0.86 < 0.95.

A topic or recent clinical interest is the possibility of using drugs to reduce infarct size is patients who have myocardial infarction within the past 24 hours. Suppose we know that in untreated patients the mean infarct size 25 (ck - g-EQ/m). Furthermore, in 8 patients treated with a drug the mean infarct size is 16. Suppose σ = 10 . Is there statistical evidence the drug is effective in reducing infarct size?
Yes, there is statistical evidence that the drug is effective in reducing infarct size because p-value is less than the significance value.
How to find hypothetical Evidence?Let us first define the hypotheses;
Null Hypothesis; H₀: µ = 25
Alternative Hypothesis; H₁: µ < 25
Standard Deviation; σ = 10
Sample mean; x' = 16
Sample size; n = 8
z-score is;
z = (16 - 25)/(10/√8)
z = -2.55
From online z-score table, the p-value is 0.005
Since p-value is less than the significance value, then we reject the null hypothesis and conclude that the drug is effective in reducing infarct size.

To use the tree house as the start of the zip line, the cable needs to be
attached to the starting tree at a height 16 feet above the ground.
To meet the slope constraint, Vince wants to change the height 7 feet and
end the zip line at a height 9 feet above the ground. He claims this vertical
change meets the slope constraint.
Test Vince's claim for Tree A and Tree B. Use specific numbers from the
situation to justify or refute whether having a vertical change of 7 feet will
satisfy the slope constraint for each tree.
The minimum allowable value of slope for tree A is 0.052 and rte slope of the zip line is 0.043 in tree B.
How to calculate the slope?The horizontal distance from starting tree is 135 feet. Therefore, the slope of the zipline will be:
= 7/135 = 0.052
The horizontal distance from starting tree for tree B is 160 feet. Therefore, the slope of the zipline will be:
= 7/160

What is composition of function?The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)). It means here function g is applied to the function of x. So, basically, a function is applied to the result of another function.
Given function is:
f ( x ) = 2 x + 2 and g ( x ) = 2 x² + 4 x
So,
(f + g)(x)
