Step-by-step explanation:

Have a great day ty!

To explain what 27 times 13 means, look at it as 27 added together 13 times. To get the answer, you could just write down the number 27, 13 times and then add the 27 numbers together.

If you have one of those old-fashioned handheld calculators, you can double check that the answer is 351 by pressing 27, then x, then 13, and then = to get the answer.

Answer:

[tex]351[/tex]

Step-by-step explanation:

[tex]27\times \:13[/tex]

Step 1: Line up the numbers; Multiply the top number by the bottom number one digit at a time starting with the ones digit (from right to left)

[tex]\begin{matrix}\space\space&2&7\\ \times \:&1&3\end{matrix}[/tex]

Step 2: Multiply the top number by the bolded digit of the bottom number

[tex]\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}[/tex]

Step 3: Multiply the bold numbers; Carry 2 to the column on the left and write 1 in the result line

[tex]7\times \:3=21\\\\\frac{\begin{matrix}\space\space&2&\space\space\\ \space\space&2&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&\space\space&1\end{matrix}}[/tex]

Step 4: Add the carried number to the multiplication

[tex]2+2\times \:3=8\\\\\frac{\begin{matrix}\space\space&\textbf{2}&\space\space\\ \space\space&\textbf{2}&7\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]

Step 5: Multiply the top number by the bolded digit of the bottom number

[tex]\frac{\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]

Step 6: Multiply the bold numbers

[tex]7\times \:1=7\\\\\frac{\begin{matrix}\space\space&\space\space&2&\textbf{7}\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&\space\space&7&\space\space\end{matrix}}[/tex]

Step 7: Multiply the bold numbers

[tex]2\times \:1=2\\\\\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&7\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&2&7&\space\space\end{matrix}}[/tex]

Step 8: Add the rows. Add zero for simplicity

[tex]\frac{\begin{matrix}\space\space&\space\space&2&7\\ \space\space&\times \:&1&3\end{matrix}}{\begin{matrix}\space\space&0&8&1\\ \space\space&2&7&0\end{matrix}}[/tex]

[tex]81 + 270 = 351[/tex]

Therefore 27 times 3 is 351

Answer:

Step-by-step explanation:

take 60 degree as reference angle

using sin rule

sin 60=opposite/hypotenuse

[tex]\sqrt{3}[/tex]/2=x/8[tex]\sqrt{5}[/tex](do cross multiplication)

2x=[tex]\sqrt{3[/tex] *8[tex]\sqrt{5}[/tex]

2x=8[tex]\sqrt{15}[/tex]

x=8[tex]\sqrt{15}[/tex]/2

x=4[tex]\sqrt{15}[/tex]

for y

using pythagoras theorem

h^2=p^2+b^2

(8[tex]\sqrt{5}[/tex] )^2=(4[tex]\sqrt{5}[/tex] )^2+b^2

320=80+b^2

320-80=b^2

240=b^2

[tex]\sqrt{240}[/tex] =b

4[tex]\sqrt{15}[/tex]=y

First you need to translate (or move) to the right 1 unit, the translate (or move) downwards 5 units.

Then, reflect the points over the y-axis (reflecting is like when you see your reflection in a mirror, how your hand lines up with the hand in the mirror)

Answer:

f(x)=x^2+4x-21

Step-by-step explanation:

Answer:

f(x) = (x + 7)  (x - 3)

Step-by-step explanation:

f(x)=(x+[tex]2)^{2}[/tex]-25

(x + 7) (x - 3) we put the 2 x's because of the (x+2)^2

now the + 7 and - 3, multiply the 2 numbers = -21 then use those 2 in

(x+2)^2 to add for the answer = -25

Answer:

8, 6, 3, 2, 1

Step-by-step explanation:

g(x) = -x + 3

using g(x),

g(-5) = (-1 x -5) + 3

= 5 + 3

= 8

g(-3) = (-1 x -3) + 3

= 3  + 3

= 6

g(0) = 0 + 3

= 3

g(1) = -1 + 3

= 2

g(2) = -2 + 3

= 1

Answer:

FV= $10,342.64

Step-by-step explanation:

Giving the following information:

Initial Investment (PV)= $2,500

Interest rate (i)= 0.095/12= 0.00792

Number of periods (n)= 15*12= 180

To calculate the future value (FV), we need to use the following formula:

FV= PV*(1 + i)^n

FV= 2,500*(1.00792^180)

FV= $10,342.64

110 + 65 + 30 = $205

Answer: Calebs total regular monthly expenses would be $205

Answer:

  $1200.00

Step-by-step explanation:

The balance is given by the formula ...

  A = Pe^(rt) . . . . . principal P invested at annual rate r for t years

Using your numbers, we can find P to be ...

  P = Ae^(-rt) = $1720·e^(-0.045·8) = $1720·e^-0.36

  P ≈ $1200.00

Answer:

D. 3120

Step-by-step explanation:

How many sides does a hexagon have? Six. Let's begin our equation with 6. The area of a triangle formula would be: 1/2 bh. And a hexagon is just six triangles put together. Now our equation is: 6 (1/2 bh) What's bh then? B (base)= 8in. The base is usually always at the bottom. Now we take 10 and add it into the equation. Next we would multiply this by 13. Our equation is now: 6(1/2*8*10)*13. What do you get then? 3120.

For Part B:  Portia's new fish require complete darkness for 12 hours a day. Rather than buying a blackout curtain for her room, she decides to make an aquarium cover out of a tropical print, with a blackout liner. How much tropical print fabric will she need to purchase in order to cover the top and sides of the aquarium?

Now, we're dealing with surface area. What is surface area, anyway? Surface area is the sum of all faces. There are 2 hexagonal faces and 6 sides.

What is 6*1/2 *8? 24! Now what's 10*24? That's right, 240!

8*13=104

6(104)=624

624+240=864

Answer:

Answer:

on the 5th week they would both have the same amount of money they would both have a total of 85$

Step-by-step explanation:

The number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

The solution of the equation means the value of the unknown or variable.

Let x be the number of the weeks and y be the total amount.

Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save $12 per week.

Then the equations will be

y = 5x + 60    ....1

y = 12x + 25  ....2

Subtract equation 1 from equation 2. Then we have

7x – 35 = 0

       7x = 35

         x = 5 weeks

Then the number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

Answer:

A: 57

Step-by-step explanation:

We are told that;

When x = 7, log y = 1.755

Since we want to find the value of y when x = 7, and the log function is in base 10, we will just use anti log to solve for y in the equation.

Thus;

Log₁₀y = 1.755

y = 10^(1.755)

y = 56.89

Approximating to a whole number gives;

y = 57

Answer:

60% decrease

Step-by-step explanation:

Subtract to find how much money it went down by

95 - 38= 57

then use proportions

x/100 = 57/95

then cross multiply

5700 = 95x

60 = x
