Answer:
a=55
Step-by-step explanation:
This question is asking for you to find the whole (a), given a part (11). This can be done through multiplication. 20% is 1/5 of 100%. This means to find the whole number, you should multiply the part by 5. 11*5=55. So, a must equal 55.
We can check this answer by working backward. Do this by finding 20% of 55, and checking to see if it is 11. To find a percentage of a number, multiply that number by the percent in decimal form. So, 20% of 55 is equal to 0.2*55, which is 11. Therefore, the answer is correct.
Answer: A=55
Step-by-step explanation: 20% of A is 11. 20% of 55 is 11. 55=a
All you do is divide 11 by .2 (11/.2)
solve for x to the nearest tenth

1/4c - 1 + 1/4c ≥ 3
Answer please
Answer:
c ≥ 8
Step-by-step explanation:
1/4c − 1 + 1/4c ≥ 3
Step 1: Add 1/4 to 1/4, since they are on the same side of the equation
1/4 + 1/4c - 1 ≥ 3
1/4 + 1/4 = 1 + 1 / 4
= 2/4
= 1/2
Step 2: Put together the equation
1/2c - 1 ≥ 3
Step 3: Add 1 to both sides.
1/2c − 1 + 1 ≥ 3 + 1
1/2c ≥ 4
Step 4: Multiply both sides by 2.
2 × 1/2c ≥ 2 × 4
c ≥ 8

a teacher gives a 10-point to a class of 10 children.
a. is it possible for 9 of the 10 to score above average on the test? if so, give an example to show how. if not, explain why not.
b. is it possible for all 10 of the children to score above average on the test? if so, give example to show how. if not, explain why not.
Please help!!
Given what we know, we can say that it is possible for 9 out of 10 students to score above average, but it is not possible for all 10 to score above average.
How do we calculate an average score?In order to calculate the average score of the students, we must use addition.
We have to add all of the scores, in this case, 10 scores, and then divide by the number of scores.
One example of 9 out of 10 students scoring above average would be:
[tex]1 + 9 +9+9+9+9+9+9+9+9 = 82[/tex]
[tex]82/10 scores = 8.2[/tex]
This would leave us with an average score of 8.2 and 9 out of 10 students that have scored higher.
Given the way in which we calculate average scores, it is impossible for all 10 students to score above average since even if all 10 students get a perfect score, that would then become the average.

The actual length of a table is 45 1/2 inches. Harriet estimates the length of the table and finds her percent to be less than 4% What range of values represents Hamel's estimated length Enter your answers as decimals or mixed numbers in simplest form by filling in the boxes Harriet's estimated length is between inches and inches
Answer:
43.68 in and 47.32 inStep-by-step explanation:
The actual length is 45 1/2 and the estimate is within 4% of error range.
The lower range is:
45 1/2 - 4% = 91/2 - 4% = 91/2*96/100 = 91*48/100 = 43.68The higher range is:
45 1/2 + 4% = 91/2 + 4% = 91/2*104/100 = 91*47/100 =47.32So the range is between:

What fraction should be added with -4/9 to get 6/17 ?
(A) 104/163 (B) 136/151 (C) 122/153
Answer:
(C) 122/153
Step-by-step explanation:
Let x be the required fraction.
(-4/9) + x = 6/17
Add both sides by 4/9
x = (6/17) + (4/9)
= (54 + 68)/153
= 122/153
Answer:
x = 122/153Step-by-step explanation:
Let's create an equation to solve for the variable x. Then, isolate the x by adding 4/9 to both sides. Lastly, simplify and solve for the x variable.
-4/9 + x = 6/17=> 4/9 - 4/9 + x = 6/17 + 4/9=> x = 6/17 + 4/9=> x = 6(9)/17(9) + 4(17)/9(17)=> x = 54/153 + 68/153=> x = 122/153Looking at all the options, Option C is matching with our result.
Hence, Option C is correct.

The first four terms of an arithmetic sequence are: a, a + d, a + 2d, a + 3d. The first
four terms of another sequence are: A, Ar, Ar2, Ar3, where r 6= 1. The eight terms
satisfy:
a + A = 27 (1)
(a + d) + (Ar) = 27 (2)
(a + 2d) + (Ar2) = 39 (3)
(a + 3d) + (Ar3) = 87 (4)
By using the substitution a = 27 − A, or otherwise, find the all eight terms
The first eight terms of the sequence are 27, 27, 39, 87, 117.378, 147.755, 178.132 and 208.509.
Determination of a given set of successive values of a sequence
By (1) we have that [tex]a = 27 - A[/tex], and we simplify the system of equations as follows:
[tex](27-A)+d + A\cdot r = 27[/tex]
[tex]d + (r-1)\cdot A = 0[/tex] (2b)
[tex](27-A) +2\cdot d + A\cdot r^{2} = 39[/tex]
[tex]2\cdot d + (r^{2}-1)\cdot A = 12[/tex] (3b)
[tex](27-A) +3\cdot d + A\cdot r^{3} = 87[/tex]
[tex]3\cdot d + (r^{3}-1)\cdot A = 60[/tex] (4b)
By (2b), we simplify the system of equations once again:
[tex]2\cdot (1-r)\cdot A+(r^{2}-1)\cdot A = 12[/tex]
[tex][2\cdot (1-r)+(r^{2}-1)]\cdot A = 12[/tex] (3c)
[tex]3\cdot (1-r)\cdot A + (r^{3}-1)\cdot A = 60[/tex]
[tex][3\cdot (1-r) + (r^{3}-1)]\cdot A = 60[/tex] (4c)
And by equalising (3c) and (4c) we have an expression in terms of [tex]r[/tex]:
[tex]\frac{12}{[2\cdot (1-r)+(r^{2}-1)]} = \frac{60}{[3\cdot (1-r)+(r^{3}-1)]}[/tex]
[tex]12\cdot [3\cdot (1-r)+(r^{3}-1)] = 60\cdot [2\cdot (1-r) + (r^{2}-1)][/tex]
[tex]36\cdot (1-r) +12\cdot (r^{3}-1) = 120\cdot (1-r)+60\cdot (r^{2}-1)[/tex]
[tex]84\cdot (1-r) +60\cdot (r^{2}-1)-12\cdot (r^{3}-1) = 0[/tex]
[tex]84-84\cdot r +60\cdot r^{2}-60-12\cdot r^{3}-12 = 0[/tex]
[tex]-12\cdot r^{3}+60\cdot r^{2}-84\cdot r +2 = 0[/tex] (5)
The roots of this third order polynomial are: [tex]r_{1} \approx 0.0242[/tex], [tex]r_{2} = 2.488 + i\,0.831[/tex] and [tex]r_{3} \approx 2.488-i\,0.831[/tex]. Since [tex]r[/tex] must be a real number, then [tex]r \approx 0.0242[/tex].
By (4c) we have the value of [tex]A[/tex]:
[tex]A = \frac{60}{3\cdot (1-0.0242)+(0.0242^{3}-1)}[/tex]
[tex]A \approx 31.130[/tex]
By (2b) we find the value of [tex]d[/tex]:
[tex]d = (1-0.0242)\cdot 31.130[/tex]
[tex]d = 30.377[/tex]
And by (1) we find the value of [tex]a[/tex]:
[tex]a = 27-A[/tex]
[tex]a = 27-31.130[/tex]
[tex]a = -4.13[/tex]
The first eight terms are calculated below:
[tex]n_{1} = 27[/tex]
[tex]n_{2} = 27[/tex]
[tex]n_{3} = 39[/tex]
[tex]n_{4} = 87[/tex]
[tex]n_{5} = [-4.13 + 4\cdot (30.377)]+(31.130)\cdot (0.0242)^{4} = 117.378[/tex]
[tex]n_{6} = [-4.13+5\cdot (30.377)+(31.130)\cdot (0.0242)^{5}] = 147.755[/tex]
[tex]n_{7} = [-4.13+6\cdot (30.377)\cdot (31.130)\cdot (0.0242)^{6}] = 178.132[/tex]
[tex]n_{8} = [-4.13+7\cdot (30.377)\cdot (31.130)\cdot (0.0242)^{7}] = 208.509[/tex]
The first eight terms of the sequence are 27, 27, 39, 87, 117.378, 147.755, 178.132 and 208.509. [tex]\blacksquare[/tex]

How could the partial strategy be applied to 2 digit by 2 digit multiplication problem?
The partial product method involves multiplying each digit of one number in turn with each digit of another where each digit keeps its place. (So the 2 in 23 would actually be 20.) For example, 23 x 42 would become (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).
