Answer:

62

Step-by-step explanation:

60 + 58 + y = 180

118 + y = 180

y = 180 - 118

y = 62

Answer:

1250 women

Step-by-step explanation:

1500 / 6 = 250

250 x 5 = 1250

hope this helps

Answer:

There are 1,250 women

Step-by-step explanation:

If the ratio of men to women is 6 to 5, and there are 1,500 men, the actual ratio of men to women is 1,500 to x, where x is equal to the amount of women at the college.

Since 6/5 is equal to 1,500/x, you cross multiply to find that 7,500 is eual to 6x.

Divide both sides by 6 to find that x is equal to 1,250 women.

Answer:

169 meters

Step-by-step explanation:

52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)

13^2=169 (to find the area you square the length of each side)

Answer: If your asking what c is its 9

Step-by-step explanation: How I did it was I did 72/8, which is 9. How I checked was I did 8*9 and I got 72

C is 9 if you multiply 8 and c to get 72.

Answer:

The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m

The equation would be:

144 x 3.14 - 64 x 3.14 = 251.2

Step-by-step explanation:

First, you need to find out what the whole circle is:

The whole circle is 452.16

Then, find the inner circle :

8 x 8 x 3.14  

200.96

Last, subtract the whole by the inner:

452.16 - 200.96 = 251.2

hope this helps!

Answer:

[tex]x=-15.5[/tex]

Step-by-step explanation:

Write down what the problem is saying;

[tex]6(x+9)=2(x-4)[/tex]

Distribute;

[tex]6(x+9)=2(x-4)\\\\(6)(x)+(9)(6)=(2)(x)+(2)(-4)\\[/tex]

Simplify,

[tex]6x + 54 = 2x - 8[/tex]

Inverse operations,

[tex]6x + 54 = 2x - 8\\-2x\\\\4x + 54 = -8\\-54\\\\4x = - 62\\/4\\\\x =-15.5[/tex]

Answer:

4m² + 11m + 6

Step-by-step explanation:

Use foil to expand this value.

(4m+3)(m+2)

Multiply the first terms in the two brackets.

Then multiply the two outer terms.

Followed by multiplying the inner terms.

Finally multiply the last terms

= (4m+3)(m+2)

4m² + 8m + 3m + 6

4m² + 11m + 6

Answer:

  C.  The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).

Step-by-step explanation:

The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.

Additionally, the x-term needs to match the result of multiplying out the factors.

  B.  (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)

  C.  (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)

The factors of C are zero when x=-1, x=5/2.

Answer:

120 children and 388 adults bought tickets for the swimming pool

Explanation:

Create two simultanous equations:

Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being

c

+

a

=

508

then, you now create a second equation for the prices of the tickets.

(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected

so:

1.75

c

+

2.25

a

=

1083.00

now we still know, that

a

=

508

−

c

so we can substitute it into the second formula

1.75

c

+

2.25

(

508

−

c

)

=

1083

now its just simple algebra

1.75

c

+

1143

−

2.25

c

=

1083

60

=

0.5

c

so:

c

=

120

now we know, that 120 children went to the swimming pool.

and we still have the formula from before:

a

=

508

−

c

so

a

=

388

Answer:

ladder length = 10 feet

Step-by-step explanation:

using the Pythagorean theorem:

8² + 6² = length²

64 + 36 = length²

length² = 100

length = 10 feet

Answer:

2(7b+5)

Step-by-step explanation:

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].

Have a terrificly amazing day! :D

Answer:E

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Write your formula

2. Plug it in

3. Solve

these steps will help you out with all of your surface area problems.

Like this

Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...

V = Bh                            (Pie is also known as 3.14)

your big (B) is (pie times r squared) Then you add your height.

so your formula will look like this...

V = pie times r squared...

the full formula will be...

V = (3.14) times (2.5 squared) times the height which in this case is (12)

everything together will be...

V = (3.14) (2.5^2) (12)

all you have to do is multiply all of that and you will get your answer.

The answer is...

V = 236 inches ^2                        (Just a tip, the ^ sign means to the power of)

Answer:

M = 95°

N = 67°

Step-by-step explanation:

180 - 162 = 18°

6y + 5 + 4y + 7 + 18 = 180

10y + 30 = 180

10y = 150

y = 15

M: 6(15) + 5 = 95°

N: 4(15) + 7 = 67°

Verification: 95 + 67 + 18 = 180° (correct)

Answer:

Step-by-step explanation:

Given the value 141700000, we are to express in scientific notation

The standard form is expressed as A * 10^n

A is any integer between 1 and 10

n is also any integer

141700000.= 1.47 * 10^8

Note that the decimal point was shifted back 8 times, main reason the power is 8
