Can someone help me please!!?? Eleven and seven-hundredths added to four and twenty-five hundredth the sum is

Answers

Answer:

[tex]15.32[/tex]

Step-by-step explanation:

Eleven and seven-hundredths [tex]=11+\frac{7}{100}[/tex]

(Here, [tex]\frac{1}{100}[/tex] denotes the hundredth)

Four and twenty-five hundredth [tex]=4+\frac{25}{100}[/tex]

Therefore,

Sum of Eleven and seven-hundredths added to four and twenty-five hundredth = [tex]11+\frac{7}{100}+4+\frac{25}{100}[/tex]

[tex]=15+\frac{32}{100}[/tex]

Cecilia has $780 in an account earning 5.2% simple interest. How much more interest would her account earn in 6 years with annually-compounded interest?

Answers

Answer:

$1057.3

Step-by-step explanation:

First we'll find the Interest no. 1, which is simple interest, assuming the time 1 year:

S.I= PRT/100

S.I= 780*5.2*1/100

S.I=$40.56

Now we'll find interest no.2, which is compound interest, time is 6 years, Principal amount (780) will remain the same as well as the rate thus (putting in the formula of compound interest- annual- [tex]A=P(1+\frac{R}{100} )^t[/tex]):

[tex]A= 780(1+\frac{5.2}{100})^6[/tex]

A= $1057.3

4(m-9)=2(2m+1)-40
What is the answer

Answers

Answer: i think that's right if not than t don't have a solution

Step-by-step explanation:4(m−9)=2(2m+1)−40

(4)(m)+(4)(−9)=(2)(2m)+(2)(1)+−40(Distribute)

4m+−36=4m+2+−40

4m−36=(4m)+(2+−40)(Combine Like Terms)

4m−36=4m+−38

4m−36=4m−38

Step 2: Subtract 4m from both sides.

4m−36−4m=4m−38−4m

−36=−38

Step 3: Add 36 to both sides.

−36+36=−38+36

What is the perimeter of triangle ABC?​

Answers

Answer:

[tex]Perimeter =58[/tex]

Step-by-step explanation:

Given

[tex]AB = 24[/tex]

See attachment

Required

The perimeter of ABC

First, calculate the lengths of AC and BC.

From the attachment.

[tex]Ax = Az =10[/tex]

[tex]Cx = Cy = 5[/tex]

[tex]By =Bz[/tex]

So, we have:

[tex]AC = 10 + Cx[/tex]

[tex]AC = 10 + 5[/tex]

[tex]AC = 15[/tex]

Also:

[tex]Az + Bz = AB[/tex]

[tex]Az + Bz = 24[/tex]

Recall that: [tex]Ax = Az =10[/tex]

So:

[tex]10 + Bz = 24[/tex]

[tex]Bz = 24 - 10[/tex]

[tex]Bz = 14[/tex]

So, we have:

[tex]By = Bz = 14[/tex]

To calculate BC, we have:

[tex]BC = 5 + By[/tex]

[tex]BC=5+14[/tex]

[tex]BC = 19[/tex]

The perimeter is then calculated as:

[tex]Perimeter = AB + BC + AC[/tex]

[tex]Perimeter = 24 + 19 + 15[/tex]

[tex]Perimeter = 58[/tex]

help pleaseeee!!!!!!!!!!!

Answers

okay so if the area is 324 square inches and one of the sides is 12 inches, then you would have to divide the area by the width. so, for your length you would get 27. to find the perimeter, you would add all of the sides together (12+12+27+27) and you would get 78 inches.

A 20-foot piece of wire is attached from the top of a flagpole to a stake in the ground 7 feet from the base of the pole. Find the height of the flagpole.

Answers

Answer:

18.73 feets

Step-by-step explanation:

Given that:

Horizontal distance between ground and foot of flagpole = 7 feets

Lenght of wire = 20 feets

The height of the flagpole, h can be obtained using Pythagoras :

Adjacent = sqrt( hypotenus² - opposite²)

Height of flagpole = sqrt((length of wire)² - (horizontal distance between ground and flagpole)²)

Let height of flagpole = h

h = sqrt(20² - 7²)

h = sqrt(400 - 49)

h = sqrt(351)

h = 18.73 feets

On January 1, one share of stock in the LMNOP Corp was worth $85. By
December, it lost 11.6% of its value. What is the new value of one share of LMNOP
stock?​

Answers

Answer:

$75.14

Step-by-step explanation:

The new value of one share of LMNOP stock after 11.6% increment is $75.14

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we are given that:

Initial price of the stock = $85/shareFinal price of the stock in December = initial price - 11.6% of initial price  (since it lost 11.6% of its initial value, so decrement, which is denoted by subtraction).

Now, the 11.6% of initial price is:

[tex]\dfrac{85}{100} \times 11.6 = \$9.86[/tex]

Thus, the final price of the stock in December =  $85 - $9.86 = $75.14
