What is the volume of the square pyramid shown below with sides that are 12.5 m long and a height of 16 m

Answer:

3455.75

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

Starting with 50

Took out 20

50-20 = 30

Then the balance was 0

We need to subtract 30 to get to get to 0

30-30 = 0

Taking out 30

Withdrawing 30

Spending 30

All are ways of indicating taking out 30 dollars

Answer:

On Tuesday, Devon took 30 dollars out of his checking account.

Step-by-step explanation:

Starting with: $50        -        Ending with $0

Monday: took out $20 or in other words -20   50-20=30

Tuesday: undetermined, but since that was his last day, it would correspond with $0 so, he must've took out $30 and then ended up with none in the end.

30-30=0

So, he took 30 dollars out on tuesday.

Answer:

3.2t-2.4

Step-by-step explanation:

-3.6 - 1.9t + 1.2 + 5.1t

Combine like terms

-3.6+ 1.2  - 1.9t +5.1t

-2.4        + 3.2t

Answer:  3.2t-2.4

Step-by-step explanation:

First thing you need to do is do   -1.9t+5.1t= 3.2t. Then you do -3.6+1.2= -1.2.

Then put all this together and you get 3.2t-1.2. (do not do 3.2t+-1.2 this incorrect because we left the subtracting sign

Just solve the equation

Given:

-2(3a+1) = 5(1+a)

-6a - 2 = 5 + 5a

11 a = -7

a = -7/11

Answer:

a = -7/11

Step-by-step explanation:

Distribute -2 and 5 through the parentheses, -6a - 2 = 5 + 5a

Move the Variable and constant  to a proper side, -6a - 5a = 5 + 2

Calculate like terms, -11a = 7

Divide both sides of the equation by -11, a = -7/11

Final answer, a = -7/11

Answer: 140%

Step-by-step explanation:

STEP 1: FIND THE CHANGE IN # OF PEOPLE:

initial # of people: 144

final # of people: 346

change in # of people = (final - initial)

change in # of people = (346 - 144)

change in # of people = 202

STEP 2: FIND THE % CHANGE

202/144 = x/100

(100)(202/144) = x

100(1.4) = x

140% = x

Answer:

140 %

Step-by-step explanation:

(346-144)/144 * 100

(202/144) * 100

You would need to DIVIDE by 9

Answer:

x=17

Step-by-step explanation:

divide both sides of the equation by 9

Answer:

51cm^2

Step-by-step explanation:

The formula for the area of a parallelogram is : [tex]base*height[/tex]

To work out the area of a parallelogram you would simply multiply the base of 8.5 by the height of 6, this gives you 51cm^2. This is because the formula for the area of a parallelogram is base multiplied by the height.

1) Multiply 8.5 by 6.

[tex]8.5*6=51cm^2[/tex]

Answer:

3 4/11.

Step-by-step explanation:

3/11 = 15/55

2/5 = 22/55

So a number in between  could be 20/55

= 4/11.

So the mixed number could be 3 4/11.

Answer: -19

Step-by-step explanation: when ur adding two negatives it's gonna equal a negative

Answer:

To calculate the balance after 6 years with monthly compounding, we can use the formula for compound interest:

A = P * (1 + r/n)^(n*t)

Where:

A = the final amount (balance) after t years

P = the principal amount (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times interest is compounded per year

t = the number of years

In this case:

P = $1500

r = 4% = 0.04 (as a decimal)

n = 12 (compounded monthly)

t = 6 years

Plugging in the values, we get:

A = 1500 * (1 + 0.04/12)^(12*6)

Calculating the right-hand side:

A = 1500 * (1 + 0.003333)^72

A = 1500 * (1.003333)^72

A ≈ 1500 * 1.265032

A ≈ $1897.55

Therefore, the balance after 6 years with monthly compounding, rounded to the nearest cent, is approximately $1897.55.

Answer:

Step-by-step explanation:

Answer:

112 meters squared

Step-by-step explanation:

Surface Area = 2×(3×2 + 3×10 + 2×10) = 112 meters squared

Answer:

112

Step-by-step explanation:

multiply the mass value by 16

Answer:

112 ounces are in 7 pounds

Step-by-step explanation:

because there are 16 ounces in 1 pound if you multiply 16 by 7 you will get 112 oz.

Answer:

2x - 3y = 18  (1)

5x + 9y = -10​   (2)

<=>

Multiply both sides of (1) by 5, and multiply both sides of (2) by 2, then:

10x - 15y = 90

10x + 18y = -20

Subtract (2) to (1):

=> 33y = -110 => y = -110/33

Substitute y back into (1):

=> 2*x - 3*(-110/33) = 18

=> 2*x + 10 = 18

=> 2*x = 8

=> x = 4

=> Solution: x = 4, y = -110/33

Hope this helps!

Step-by-step explanation:

Answer:

− 24 x 3

This is if you multiply the expressions

Answer:

56 cm

Step-by-step explanation:

The ratio of the lengths of the pieces is 3:4.

The longer piece is 32 cm.

We set up a proportion to find the length of the smaller piece.

Let the length of the smaller piece be x.

3 is to 4 as x is to 32

3/4 = x/32

4x = 3 * 32

4x = 96

x = 24

The smaller piece is 24 cm.

24 cm + 32 cm = 56 cm

Answer: 56 centimeters long.

Step-by-step explanation:

You can find the other value in a ratio by dividing the value given by its corresponding value in the ratio, then multiplying the quotient by the other value in the ratio.

32 is the longer piece, and 4 is longer than 3.

32 / 4 = 8.

8 * 3 = 24

The shorter piece is 24 centimeters long.

The total length of the coil is 24 + 32, or 56 centimeters long.

Well, if a = -1 and b = 4 then when we plug in the values of a and b into the expression we get:

[tex]13(-1)^{-3}\cdot4^{-1}[/tex].

Then simplify it:

[tex]-13\cdot1/4=-\frac{13}{4}[/tex].

The answer is A.

Hope this helps.

Step-by-step explanation:

Step 1:  Substitute -1 for a and 4 for b

[tex]13 * (-1)^-^3 * (4)^-^1[/tex]

[tex]13 * (-1) * \frac{1}{4}[/tex]

[tex]-\frac{13}{4}[/tex]

Answer:  Option A, [tex]-\frac{13}{4}[/tex]
