Answer:
900,000
Step-by-step explanation:
rounding is quite simple, the number 927,545, like all numbers, has different number places/values. the number 9 is in the 100,000th place and to round you look at the number in the place to the right of it which is 2. the number 2 is is less than 5 so it can't raise the number 9 to a ten. because of this, it reduces all of the other numbers to 0. leaving you with the number 900,000
7. After 8 months, Joellen has lost 75 pounds. This is a 30% decrease in her starting weight. Find
her starting weight.
Answer:
Started 100% = x pounds
30% = 75 pounds
x= 75*100÷30= 250 pounds
Starting Weight = 250 pounds
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
30% = 75 pounds
100% = 250 pounds
The starting weight was 250 pounds.
What is a percentage?
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
30% decrease = 75 pounds
Starting weight = 100%
Now,
30% = 75
Multiply 100/30 on both sides.
100/30 x 30% = 100/30 x 75 pounds
100% = 10/3x 75 pounds
100% = 10 x 25 pounds
100% = 250 pounds
Thus,
The starting weight was 250 pounds.

Find the interquartile range for a data set having the five-number summary: 5.6, 11.1, 19.2, 24.5, 33.3
A. 13.6
B. 27.7
C. 13.4
D. 14.1
Answer:
C
Step-by-step explanation:
The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁
From the five- number summary , then
Q₃ = 24.5 and Q₁ = 11.1
interquartile range = 24.5 - 11.1 = 13.4 → C

Restaurant A's chicken salad contains the same number of grams of fat as the chicken salad of restaurant C. Restaurant B's chicken salad contains 8 more grams of fat than restaurant A's chicken salad. If the total amount of fat in all three salads is 77 grams, find the number of grams of fat in each salad.
Restaurant A's chicken salad has grams of fat.
Restaurant B's chicken salad has grams of fat.
Restaurant C's chicken salad has grams of fat.
Answer:
Restaurant A and C: 23 grams of fat
Restaurant B: 31 grams of fat
Answer:
Restaurant A's chicken salad has 7.7 grams of fat.
Restaurant B's chicken salad has 61.6 grams of fat.
Restaurant C's chicken salad has 7.7 grams of fat.
Step-by-step explanation:
Restaurant A = C
Restaurant B = 8 × Restaurant A
Total Grams of Salad = 77
Let Reataurat A and C be x
and Reataurant B be 8x
so
A + B + C = 77
x + 8x + x = 77
2x + 8x = 77
10x = 77
x = 77 ÷ 10
x = 7.7
Restaurant A's chicken salad has 7.7 grams of fat.
Restaurant B's chicken salad has 61.6 grams of fat.
Restaurant C's chicken salad has 7.7 grams of fat.
If u want to crass check so
7.7 + 61.6 + 7.7 =
69.3 + 7.7 =

Round each decimal number to the nearest tenth. Then, select the best estimate for the subtraction equation 1.79 − 0.67 = ___.
1
1.1
1.2
1.3
Answer: 1.12
Step-by-step explanation:
Here 1.79 -0.67 = 1.12 ( if we subtract from the large positive number to a minimum number then it's answer always should be positive value )
Now we are looking for the rounding figure with is very near of it which is 2 decimal or percentage value
For example :
1.444- 0.67 = 0.774 ( Here last digit is 4 so its round will be 0.77)
1.444-0.677 = 0.767 ( Here last digit is 7 so its round will be 0.77)
So we will round the value if it's last digit is greater than or equal to 5 value.

9514 1404 393
Answer:
89.0
Step-by-step explanation:
One way to round a number is to add half the place value you're rounding to, then truncate at the desired place value.
Here, we want to round to a tenth (0.1), so we first add half that value:
88.98 + 0.05 = 89.03
Now, we throw away all digits after the tenths place.
89.0 . . . . our rounded value

Help find the measure of of the angle A,
Angle b
Angle c
Angle d
Angle e
Angle f
Angle g
Use degrees.
Answer:
160 degrees
Step-by-step explanation:
starting with the 110 degrees angle. the unnamed angle to the right of the 110 degrees is simply the complement of 110 to 180 degrees = 70 degrees.
then B is actually 180 - 90 - 70 = 20 degrees
and then A is the complementary angle of these 20 degrees to 180 degrees = 160 degrees.

what is the median of the number 10 12 13 15 16 19 25?
Answer:
15 is the middle number
Step-by-step explanation:
BECAUSE IF YOU COUNT FROM THE LEFT AND RIGHT AND WHICH NUMBER APPEARS IN THE MIDDLE IS YOUR MEDIAN
Answer:
15
Step-by-step explanation:
this asks for the median, and not the mean value.
please notice that these 2 values are often if not mostly different from each other.
the median just defines the middle of the value interval, so that half of the different values are left, and half are right of that median value.
here we have 7 values. do we find one, so that 3 other values are smaller, and 3 other values are bigger than that ?
that is 15.
10, 12, 13 are smaller.
16, 19 and 25 are bigger.
so, 15 is the median.
