Answer:

for A

the law

V=Bh or V=πr2h

I will use this V=Bh

V= 16·21

V= 336cm³

For E

the law

A= 1/2·(A + B)·H

A= 1/2·(14 + 8)·4

A= 44cm²

V= A·H

V= 44·4

V= 176 cm³

Answer:

53 gallons of fuel

Step-by-step explanation:

Step 1: Set up a fraction given the data (Let "x" represent the distance in miles.)

[tex]\frac{10}{250} = \frac{x}{1325}[/tex]

Step 2: Divide the given values (The given values are 10 over 250. We are doing this because we need to know the difference between those two figures.) (Trick: For this case, all you need to do is cancel both zeros and the answer is 0.04 once divided)

[tex]\frac{10}{250}\\\\10 \div 250\\\\= 0.04[/tex]

Step 3: Multiply the result to the last value (Since we've found the difference between them by division, we will have to do the opposite operation in order to find the answer.)

[tex]1325 \times 0.04\\\\= 53[/tex]

Therefore, 53 is the amount of gallons of fuel needed.

Answer:

x=3

Step-by-step explanation:

4x-8=4

4x=12

4x/4=12/4

x=3

Answer:

x = 3

Step-by-step explanation:

Add 8 to both sides.

4x = 4 + 8

Simplify 4 + 8 to 12.

4x = 12

Divide both sides by 4.

x = 12 ÷ 4

Simplify 12 ÷ 4 to 3

x = 3

Answer:

Step-by-step explanation:

log 3y = log(y)^3 (exponent)

or

= log(y)*log(y)*log(y)  (multiples)

The logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

        [tex]$\log_{b}({b^x})=x[/tex]           {where [b] is logarithmic base}

Given is the following logarithmic expression as -

y = log(3y)

We have the following logarithmic expression -

y = log(3y)

Using the identity of logarithm -

log(AB) = log(A) + log(B)

log(3y) = log(3) + log(y)

Therefore, the logarithmic expression y = log(3y) can be written as sum or difference of common logarithms as log(3y) = log(3) + log(y).

I took the MAP Test.

Answer:

B

-15 < 99 and | -9 | < | 15 |

Step-by-step explanation:

Those lines " | " refer to absolute value, meaning it is the distance from 0. You can easily get this just by cutting off a negative sign.

So we do know -9 is greater than -15 obviously, and the absolute value of -9 is 9, because -9 is 9 units from 0.

-15 is 15 units away, so when using absolute value, -15 is greater than -9.

Btw, you can only give one brainliest, you don't get the option to give two on brainly.

Just saying.

Answer:

810 AUD

Step-by-step explanation:

t is time in months: you have to substitute with the number of months given from the question.

C=65t + 30 ==> substitute t with 12 since the question provided you the number of months.

--> C = 65(12) + 30 = 780 + 30 = 810

Answer:

16 cans per minute

Step-by-step explanation:

Its simple 80 divided by 5 is 16 so ever minute 16 cans are packed.

The ratio of the cans to minutes is 80 : 5 or 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.

A machine can pack 80 cans in 5 minutes.

let's denote the number of cans with X and

Time with T

So we have to find the value of X : T

X = 80 and

T = 5 minutes

X : T = 80 : 5  or

X : T = 16 : 1   (divide by 5 on both sides)

It means the machine can pack 16 cans per minute.

Thus, the ratio of the cans to minutes is 16 : 1, and the machine can pack 16 cans per minute if a machine can pack 80 cans in 5 minutes.

Answer:

x= 0

Step-by-step explanation:

6x-4=2(3x-2)

or,6x-4=6x-4

or,x=o

There are infinite solution of the expression.

We have to given that,

An expression to solve,

6x - 4 = 2 (3x - 2)

Now, We can simplify as,

6x - 4 = 2 (3x - 2)

Apply distributive property,

6x - 4 = 6x - 4

Combine like terms,

6x - 6x = 4 - 4

0 = 0

Hence, There are infinite solution of the expression.

#SPJ6

Answer:

187.5 pounds

Step-by-step explanation:

Fraction of sand = 2/5

Fraction of clay = 2/5

Fraction of peat = 1/5

Pounds of sand = 75

The total pounds of soil required to make Correct mixture : let that be x

Hence,

Using the sand Fraction and pounds which we know :

2/5 of x = 75

2x / 5 = 75

Cross multiply :

2x = 75 * 5

2x = 375

x = 375 / 2

x = 187.5

Required pond of sand =187.5 pounds

Answer:

The value for x is -2 and the value for y is -10 .

Step-by-step explanation:

Firstly , let's write the equations

solving equation 1 to get the values of x

          or ,    -2x+3=7          

      or,  -2x+3-3 =7-3 (subtracting -3 on both sides )

       or ,  -2x=4

        or,  -2x/2  =   4/2  (dividing  by two on both sides )

         or ,  -x =2

           or  x = -2

now let's substitute the values of x  in the equation 2

           3x+1 =5+y (writing second equation as it is )

           or, 3x+1-1=5+y-1 (subtracting  -1 on both sides )

            or , 3x = 4+y  

              or , 3 × -2 = 4+y  (substituting the values of x from equation 1 )

                or ,  -6  =  4 +y

                   or ,  -6-4 = 4+y-4 ( subtracting -4 on both sides  )

                     or ,    -10 = y

      Therefore the values of x and y is -2 and  -10 respectively .

                Hope it helped you .  If you find the answer useful  please rate brainliest , If not Thanks anyway .
