Answer 1

Answer:

30 square millimeters

Step-by-step explanation:

3 x 3 = 9

3 x 1 = 3

there are two sides with the area 9 therefore...

9 x 2 = 18

There are four sides with the area 3 therefore...

3 x 4 = 12

Therefore the suface area is

12 + 18 = 30

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?

Answers

Answer:

[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]

18 bracelets in 3 hours

Answers

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

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?

Answers

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.

The total surface area of the cone is 542.592 square mm

Total surface area of a cone

The 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

A hot dog costs $1 at the ballpark. Which equation shows the total cost, C, of n hot dogs?
⚫️n = 1c
⚫️n = 1+c
⚫️c = 1n
⚫️c = 1 + n

Answers

c=1n is the answer because the cost of hotdogs equals the price times the number of hotdogs

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

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.

Answers

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 = 2z

We know that,

Cuboid ( total surface area)= 2lb+2lh+2hb cubic units

So 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 = lbh

We got the dimensions of the cuboid, i.e.

Then, solve.

Cuboid V = lbh15 cm * 9 cm * 6 cm810 cm^3

Hence,the volume of the cuboid will be 810 cm^3

Somerset Corporation just completed its fiscal year ended January 31, 2021. All sales were on account and totaled 650,000 for the year.

Round and enter to one decimal place only.

Answers

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.

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

Answers

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

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

The three angles are 64° , 64° , 52°

Trigonometry in baseball

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?
