Answer:
31
Step-by-step explanation:
They're technically asking you to find the missing angle. 61+57 is 118. 180-118 is 62. Since they're asking 2x, you do 62 divided by 2, which is 31.
The weeks will it take the grass to grow 12 over 7 centimeters is 3 weeks.
<h3>What is the unitary method?</h3>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
St. Augustine grass can grow at the rate of 4 over 7 centimeters per week.
The weeks will it take the grass to grow 12 over 7 centimeters
4/7 x = 12/ 7
28x = 84
x = 84/28
x = 3
The weeks will it take the grass to grow 12 over 7 centimeters is 3 weeks.

⓵ When I see fractions, I usually start by transforming my fraction into a decimal because I find it easier to work with :
5 ½ = 5 + (1 ÷ 2) = 5 + 0,5 = 5,5%
⓶ Then, once you got rid of that fraction, I usually transform a percentage into a decimal because, again, I find it easier to work with :
5,5% = 5,5 ÷ 100 = 0,055
⓷ The next step would be to add both prices together in order to get one unique price to work with instead of two :
$17,99 + $25,50 = $43,49
⓸ Next, you need to multiply the total price you calculated at #3 by the decimal of the pourcentage that you calculated at #2 in order to find the tax amount on his purchase :
5 ½% of $43,49
↓
5,5% of $43,49
↓
0,055 × $43,49 = 2,39195
Since we are calculating money, you need to round up this number at the hundredths, wich means that you’ll end up with about $2,39 of taxes on your total purchase!
⓹ The last and final step is to add the tax amount that you just calculated in #4 to the total price you calculated at #3 in order to find the total of his purchase including the 5 ½% taxes :
$43,49 + $2,39 = $45,88
If you wanted to be a tiny bit more precise, you could have decided not to round up the tax amount in #4 and just round up the final amount ↠
$43,49 + 2,39195 = 45,88195
Wich would, in this case, given you the same exact answer which is : $45,88
But it is important to keep in mind that sometimes the answer might vary if you round up only at the end, depends on your teacher’s exigences more than anything!
→ So the final answer is that his total purchase including a 5 ½% tax is : $45,88!
I really hope this helps, if there’s anything just let me know! ☻
Slope is the change in Y ( vertical) over the change in X( horizontal).
The slope would be -2 /3
You would multiply the horizontal distance by the slope:
-2/3 x 12 = -8
The answer would be D. v(h)=-2/3h, and the vertical distance is -8 feet.
his average speed as he ran: V = S/t = 100/12 = 25/3 (m/s)
ok done. Thank to me :>
