Find the area of the compound figure

Answer:

To find the surface area of a rectangular prism you must multiple the length and the width. You can choose the top and do 2(L*W) and one of the square sides 2(L*W) and the front 2(L*W) and add it all up.

2(L*W)+2(L*W)+2(L*W)= surface area

There is a 2 because there are two side of a rectangular that are the same. Since there are 6 sides on a rectangle. Only 3 pairs are similar.

Hope this helps :)

Answer:

166.52 cubic feet.

Step-by-step explanation:

We can Know the volume of a by using the expression below

V =[ (4/3)πr^3] .............eqn(1)

Given Diameter= 8.6 ft

radius= Diameter/ 2 = (8.6 ft)/2 = 4.3 ft

Eqn(1) gives the formula for volume of a WHOLE sphere, but what we need is

HALF of whole sphere, then we have

V =[ (4/3)πr^3] / 2

Then eqn(1) becomes [ (2/3)πr^3]

Volume of hemisphere

= [ (2/3)πr^3].....eqn(2)

If we substitute into eqn(2) we have

Radius= 4.3 ft

V(hemisphere) = (2/3)π(4.3)^3

= 166.52 cubic feet.

Hence, the volume of a hemisphere is

166.52 cubic feet.

Answer:

x = 3, y= -1

Step-by-step explanation:

12x-y=37

-5x-y=-14

12x-y=37

-1(-5x-y)=-1(-14)

12x-y+5x+y=37+14

17x = 51

(17x)/17 = 51/17

x = 3

12(3)-y=37

36-y=37

-y = 1

y = -1

Answer:

the GCF is 3x^3

Step-by-step explanation:

Identifying the greatest common factor of an expression like this one involves finding the GCF of each term  when the terms are placed side by side:  the GCF of -15x^3 and 6x^4 is 3x^3, because 3 and x^3 are the largest factors of their type (constant, power of x) that will divide evenly into -15x^3 and 6x^4.

The end result is 3x^3(-5, 2x).  Once again, the GCF is 3x^3.

Conversion a mixed number 8 1/4

to a improper fraction: 8 1/4 = 8 1/4

= 8 · 4 + 1/4

= 32 + 1/4

= 33/4

To find new numerator:

a) Multiply the whole number 8 by the denominator 4. Whole number 8 equally 8 * 4/4

= 32/4

b) Add the answer from previous step 32 to the numerator 1. New numerator is 32 + 1 = 33

c) Write a previous answer (new numerator 33) over the denominator 4.

Eight and one quarter is thirty-three quarters

Conversion a mixed number 3 2/5

to a improper fraction: 3 2/5 = 3 2/5

= 3 · 5 + 2/5

= 15 + 2/5

= 17/5

To find new numerator:

a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/5 = 15/5

b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17

c) Write a previous answer (new numerator 17) over the denominator 5.

Three and two fifths is seventeen fifths

Subtract: 33/4

- 17/5

= 33 · 5/4 · 5

- 17 · 4/5 · 4

= 165/20- 68/20

= 165 - 68/20

= 97/20

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 5) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 5 = 20. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - thirty-three quarters minus seventeen fifths = ninety-seven twentieths.

Conversion a mixed number 2 1/3

to a improper fraction: 2 1/3 = 2 1/3

= 2 · 3 + 1/3  

= 6 + 1/3  

= 7/3

To find new numerator:

a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3

= 6/3

b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7

c) Write a previous answer (new numerator 7) over the denominator 3.

Two and one third is seven thirds

Subtract: 7/3  - 1/4  

= 7 · 4/3 · 4 - 1 · 3/4 · 3  

= 28/12- 3/12

= 28 - 3/12

= 25/12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - seven thirds minus one quarter = twenty-five twelfths.

Subtract: the result of step No. 3 - the result of step No. 5 = 97/

20  - 25/12  

= 97 · 3/20 · 3  - 25 · 5/12 · 5  

= 291/60  - 125/60

= 291 - 125/60

= 166/60

= 2 · 83/2 · 30

= 83/30

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(20, 12) = 60. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 20 × 12 = 240. In the next intermediate step, , cancel by a common factor of 2 gives 83/30

In words - ninety-seven twentieths minus twenty-five twelfths = eighty-three thirtieths.

Step-by-step explanation:

83/30 is the awnser

you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x

Answer:

Step-by-step explanation:

I searched all of this on YT to try and help

so first we need to know the area of a Trapezoid

A = 1/2h(b + b)

86 = 1/2(18 + b)4

we dont know the base where going to put b

we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.

172 = (18 + b)4

the 4 is multipling so divide it on both ends.

43 = (18 + b)

then do the opposite operation on the 18, by subtracting 18 on both sides.

25 = b

is the base

check the work by plugging it back in

A = 1/2h(b + b)

A = 1/2 4(18+25)

A = 1/2 4(43)

A = 1/2(172)

A = 86in

Answer:

After 3 years Mariah will have $1,805.40 while her sister Isabel will have $1,889.56.

Step-by-step explanation:

Since Mariah will deposit $ 1,530 in an account that earns 6% simple interest every year, while her sister Isabel will deposit $ 1,500 in an account that earns 8% interest compounded annually, and the deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts, to determine the balances of Mariah's account and Isabel account at the end of the 3 years the following calculations must be performed:

Mariah:

1,530 + ((1,530 x 0.06) x 3) = X

1,530 + (91.8 x 3) = X

1,530 + 275.4 = X

1,805.4 = X

Isabel:

1,500 x (1 + 0.08 / 1) ^ 3x1 = X

1,500 x 1.08 ^ 3 = X

1,500 x 1,259712 = X

1,889.568 = X

Therefore, after 3 years Mariah will have $ 1,805.40 while her sister Isabel will have $ 1,889.56.

Answer:

8800 yards

Step-by-step explanation:

The total number of yards ran by Dexter for his training is given by the equation A = 8800 yards

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the total number of yards ran by Dexter be A

Now , the total number of miles ran by Dexter = 5 miles

where from the unit conversion ,

1 mile = 1760 yards

So , the total number of yards ran by Dexter for his training A = 5 x 1760

The total number of yards ran by Dexter for his training A = 8800 yards

Hence , the number of yards is 8800 yards
