Answer:

A

Step-by-step explanation:

using the sine ratio in the right triangle, then

sin 45° = \frac{opposite}{hypotenuse} = \frac{x}{5}

multiply both sides by 5

note the exact value of sin 45° = \frac{\sqrt{2} }{2}

x = 5 × sin 45° = 5 × \frac{\sqrt{2} }{2} = \frac{5\sqrt{2} }{2}

Yasmina eats lunch at Chipotle for $5.25 per day for five days a week. How much does lunch cost...
Paul [167]

Answer:

Step-by-step explanation:

Yasmina:

5.25 x  5 = 26.25 per week

5.25 x 20 = 105 per month

5.25 x 260 = 1365 per year

Camila:

9.75 x 35 = $ 341.25 earnings per week

341.25  x 0.20 = 68.25 saves per week

9.75x35x 4= 1365 earnings per month

1365 x 0.20 = 273 saves per month

9.75 x 35 x 52 =  17745 earnings per year

17745 x 0.20 = 3549 saves per year

I just need a little help on this ??! Please.

1. Since it's m - 7 you would have 7 to both sides so you would in fact have m < 13. If you double check your answer, you see that if m is say 12 (because 12 is obviously less than 13), 12 - 7 < 6

2. Again, use the same process on this problem as the first one. Add 8 to each sides because it's you're subtracting 8 from n. So you end up with n > 13. Check your answer. Say n is 14. 14 - 8 > 5

3. This one is different because you are adding 5 to p. So in order to get p by itself, you need to subtract 5 from both sides. p < 5. Say p is 4, 4 + 5 < 10.

When working with problems like these, you need to isolate the variable on one side and get it by itself.
