4 0

Answer:

A - 22

Step-by-step explanation:

This is because when you add 90 and 68 you get 158. There are 180 degrees in a triangle so you do 180-158 to get 22.

Missing pattern 24,21, blank 15 blank ,blank
never [62]
To figure out this pattern, let's see if there's a constant rule that this sequence follows.
From 24 to 21, you're subtracting 3.
Let's try n-3, and fill in the blanks as we go.
24 - 3 = 21.
21 - 3 = 18.
18 - 3 = 15.
15 - 3 = 12.
12 - 3 = 9.
It seems that n-3 works as a rule, so your rule is:
N-3.
The missing blanks are:
18, 12, and 9.
I hope this helps!

Two of the golf scores at the local tournament were unreadable, but the mean score was 85 and the lowest score was 75. if the re
Vika [28.1K]

Step-by-step explanation:

Assuming the readable scores are:

100, 82, 95, __ , 90, 81, 75, 83, __

We know the mean (or average) is 85, so:

85 = (100 + 82 + 95 + x + 90 + 81 + 75 + 83 + y) / 9

765 = 606 + x + y

159 = x + y

We know the lowest score is 75, so x and y must be at least 76.  Possible answers are:

76 and 83

77 and 82

78 and 81

79 and 80

80 and 79

81 and 78

82 and 77

83 and 76

7) David bought a computer that was 20% off the regular price of $1080. If an 8% sales tax was added to the cost of the computer
Aneli [31]
Hello there! I can help you!

7. Okay. So the computer was originally $1,080, and the discount is 20%, but David would still have to pay 80% of the original price. To find the sale price, let's multiply. 1,080 * 80% (0.8) is 864. The sale price of the compuet is $864, but now we must add the sales tax to find the total price. We will multiply by 108%, because 100% (representing the price + 8% is 108%, and doing this will get us stright to the total price. 864 * 108% (1.08) is 933.12. There. David paid a total price of $933.12 for the computer.

8. Okay. So we are looking for the amount of discount for the sweater Suzanne bought. First off, let's subtract the prices to find the difference. 40 - 25 is 15. Now, let's divide that by 40 (the original price) to find the discount. 15/40 is 0.375. Or 37.5% when converted into a percentage. There. Suzanne received a 37.5% discount on the sweater when she bought it.

9. So the car was bought for x dollars. 0.88 represents 88%, so the value of the car is 88% of the previous year. An expression that is a way to describe the change in car value is x * (100 - 0.12)^t, because you car loses 12% of the remaining value each year, which leaves 88% of it remaining, and having the t as the exponent represents the number of years. That expression helps find the value of the car currently and can help you compare the values.
