PLEASE HELP!
WILL GIVE 20 PTS!!!

Answer:

1:

[tex] \frac{m}{8} + 15 = 20 \\ m + 120 = 160 \\ m = 160 - 120 \\ m = 40[/tex]

[tex]4 = \frac{m}{3} - 6 \\ 12 = m - 18 \\ - m = - 18 - 12 \\ - m = - 30 \\ m = 30[/tex]

44=4t+8

-4t=8-44

-4t=-36

t=9

And the last one is

15+2x=75

2x=75-15

2x=60

x=30

Hope this helps :)

Answer:

A

Step-by-step explanation:

Volume of cylinder= πr²h, where r is the radius

Volume of concrete

= volume of large cylinder -volume of smaller hollow cylinder

Large cylinder:

Diameter= 7m

Since radius= ½(diameter),

Radius= 7 ÷2= 3.5m

Height= 3m

Volume of large cylinder

= π(3.5)²(3)

= 36.75π m³

Small hollow cylinder:

Diameter= 4m

Radius= 4 ÷2= 2m

Height= 3m

Volume of small hollow cylinder

= π(2)²(3)

= 12π m³

Substitute vol. of large and small hollow cylinder with 36.75π and 12π respectively, then substitute 22/7 for π:

Volume of concrete

= 36.75π -12π

= 24.75π

[tex] = 24.75( \frac{22}{7} ) \\ = 77.79 \: m^{3} [/tex]

Answer:

C) 0.375

Step-by-step explanation:

Ok, so the question is to write 3/8 as a decimal. To turn a fraction into a decimal, you divide the numerator by the denominator.

3 ÷ 8 = 0.375

You can check your work by seeing if 0.375 as a fraction simplifies to 3/8

0.375 = 375/1000

Divide 375 and 1000 by 125 to get your simplified fraction, 3/8.

Answer:

these are triangle problems, they are difficult unless you keep in mind that there is an invisible triangle and you use the Mnemonic SOH CAH TOA to keep sin, cos, and tan,  straight..

Step-by-step explanation:

what do we know about the imaginary triangle that is being made from Susan to the lighthouse?  that from Susan's feet  to the lighthouse base is 200 m  so that side of the imaginary triangle is 200 meters.. got it... Susan's eyes are 1.22 meters up   and that her angle of looking up at the top of the lighthouse is 9 degrees.. okay .. we have enough info to solve this.  B/c we have an angle and also the adjacent ( next to )  side to that angle  , great

B/c we have the adjacent side and the angle.. and we want to know the Opposite side.. which will be the height of the light house,  use one of the SOH CAH TOA formulas for those three pieces of info in it.. I see that that TOA has all of those.  Tan(Ф)= Opp / Adj  

Tan(Ф) is our angle

Opp is the Opposite side that we want to find

Adj is the Adjacent side that we know.. 200

Tan(9)=Opp / 200

use algebra to rearrange our formula

Tan(Ф)*Adj = Opp

Tan(9)*200 = Opp

I'll use my calculator to figure out what tan(9) is b/c I don't have that memorized :P and multiply that by 200

31.677 m

Also.. b/c we just figured out the triangle from  Susan's eyes to the lighthouse.. we have to add her eye height off the ground to our answer

31.677+1.22= 32.897

yeah   32.9     looks like the right answer

Answer:

1.1217 x 10^10

Step-by-step explanation:

Since the question is Which number is larger than 1.1213 × 10^10 1.1217 x 10^10

is a number larger then 1.1213 × 10^10 because it has the same exponent as the problem in the question but 1.1217 has .0004 more then the problem in the question.

Answer:

x=1/2

Step-by-step explanation:

7x−6=3+x−5−2x

Step 1: Simplify both sides of the equation.

7x−6=3+x−5−2x

7x+−6=3+x+−5+−2x

7x−6=(x+−2x)+(3+−5)(Combine Like Terms)

7x−6=−x+−2

7x−6=−x−2

Step 2: Add x to both sides.

7x−6+x=−x−2+x

8x−6=−2

Step 3: Add 6 to both sides.

8x−6+6=−2+6

8x=4

Step 4: Divide both sides by 8.

8x /8 = 4 /8

x= 1 /2

Answer:

0

Step-by-step explanation:

We need to factor the GCF (Greatest Common Factor).

The resulting term is a product of the GCF and the original expression divided by the GCF.

In our example, the GCF is equal to X + 2.

I'm not sure if its 0

But mine is "0"

given data

cost of 2.5 pounds is $5.6

A. What is the cost of one pound of cheese? Type your answer in the box.

if 2.5 pounds is $5.6

the 1 pound will cost x

cross multiply we have

x=5.6/2.5

x=$2.24

B. Mrs. Peterson bought 4.75 pounds of cheese. How much money did Mrs. Peterson spend on cheese?

we know that 1 pound cost $2.24

therefore 4.75pound, she will spend= 4.75*2.24=$10.64

C. How could you find the cost for 5 pounds of cheese without finding the cost per pound?

we can use the rate for 2.5 pounds at $5.6

i.e 2.5 pounds at $5.6

   5 pounds will cost x

cross multiply we have

x=5*5.6/2.5

x=28/2.5

x=$11.2

Answer:

Assertive behavior is all about standing up for yourself, but aggression usually involves threatening, attacking, or (to a lesser degree) ignoring others.
