Answer: 22

Step-by-step explanation:

The area of the picture =l×b = 20×16=320

The length of the frame is 16

If the width is x ( and it's uniform)

672- 320= 352

Area of the frame = 16× x=352

x=352/16

x = 22

stiks02 [169]
The sample space for the experiment has a total of  36  possibilities.

Sample space  for an odd sum is { 1,2  1,4  1,6  2,1  2,3  2,5  3,2  3,4 3,6  4,1  4,3  4,5  5,2 ,5,4  5,6  6,1  6,3  6,5 }

You decide to put $150 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate
zheka24 [161]
The formula is
A=p (1+r/k)^kt
A future value 3000
P present value 150
R interest rate 0.025
T time?
3000=150 (1+0.025/12)^12t
Solve for t
3000/150=(1+0.025/12)^12t
Take the log
Log (3000/150)=log (1+0.025/12)×12t
12t=Log (3000/150)÷log (1+0.025/12)
T=(log(3,000÷150)÷log(1+0.025÷12))÷12
T=119.95 years

2 • (3 • 7) and (2 • 3) • 7 = ?
shusha [124]

Answer:

First one is 42 and the second one is 48.

Step-by-step explanation:

Start with parentheses. I'll use the first one as an example. 3 x 7 is 21. Now that the parentheses are done, multiply it by whatever's left. 21 x 2, that's 42. For the other one, 2 x 3 is 6, x 7, is 48. Have a good day :)
