Find a2 and a3 for the geometric sequence 4, a2, a3, 108.
9514 1404 393
Answer:
a2 = 12
a3 = 36
Step-by-step explanation:
Terms of a geometric sequence have a common ratio. If we call that ratio r, then we have ...
a2 = 4r
a3 = (a2)r = 4r^2
108 = (a3)r = 4r^3
27 = r^3 . . . . . . . . . . . divide by 4
3 = r . . . . . . . . . . cube root
__
a2 = 4(3) = 12
a3 = 12(3) = 36
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 =

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.

I need help with this problem.
How do I do it?
Answer:
20
Step-by-step explanation:
For the area of a rectangle we use A = L* W
We know area or A = 420
and we know length or L = 21
Now we need to find the width or W
(420) = (21) * W
Divide both sides of the equation by 21 to isolate the variable.
That leaves us with:
W = 20

88.98 to the nearest tenth
Answer:
89 is the answer
Step-by-step explanation:
88.98
= 89
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

Yes this could be true if there were 127 students taking algebra but not biology, and there were 77 students taking biology but not algebra
Step-by-step explanation:
Not college math just simple subtraction?
Let [tex]a[/tex] be the amount of students taking only algebra
Let [tex]b[/tex] be the amount of students taking only biology.

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
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.
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.
