The mean of 16 items was found to be 30. On rechecking, it was found that two items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Find the correct mean. Round to the nearest Hundredth.
Answers
Answer: The answer is 31.25 because The mean of 16 items was found to be 30. So once you checked, it was that 2 items were wrongly taken as 22 and 18 instead of 32 and 28 respectively. Sum = mean no of items = 30 16 = 480
(32 +28) – (22 + 18) = 20
Correct mean = = 31.25

A dealer sold 200 tennis racquets. Some were sold at $18 each and others were sold at $33 each. The total sales were 4,800. How many of each priced racquet was sold?
Explain your answer.
Answers
Then, 200 - x = number that sell for $33 each
18x + 33(200 - x) = 4800
18x + 6600 - 33x = 4800
-15x = -1800
x = 120
There were 120 racquets selling for $18 each and 80 racquets selling for $33 each.

Answers
Answer/Step-by-step explanation:
1.
✔️a = 180 - 110 (consecutive angles are supplementary)
a = 70°
✔️b = a (corresponding angles are congruent)
b = 70°
✔️c = 110° (alternate interior angles are congruent)
2.
✔️a = 180 - 120 (linear pair)
a = 60°
✔️b = a (corresponding angles are congruent)
b = 60°
✔️c = a (alternate interior angles are congruent)
c = 60°
3.
✔️a = 55° (corresponding angles are congruent)
✔️b = 55° (Vertical angles are congruent)
✔️c = 180 - 55 = 125° (linear pair)
4.
✔️a = 115° (corresponding angles are congruent)
✔️b = 180 - a (linear pair)
b = 180 - 115
b = 65°
✔️c = b (vertical angles are congruent)
c = 65°
5.
✔️a = 180 - 25 = 155° (supplementary angles)
✔️b = 25° (corresponding angles)
✔️c = 25° (vertical angles)
6.
✔️a = 180 - 10 = 170° (linear pair)
✔️b = a (corresponding angles are congruent)
b = 170°
✔️c = 10° (corresponding angles are congruent)

Answers
The equations that the number 7 makes true will be 11/14 × 7 = 11/2, 3/35 × 7 = 3/5, and 5/7 × 7= 5. Then the correct options are C, D, and E.
What is an equivalent expression?The equivalent is the expression that is in different forms but is equal to the same value.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equations do the number 7 make true will be given as,
Let's check all the options. Then we have
20/21 × 7 = 3/20
20 / 3 ≠ 3 / 20
13/28 × 7 = 5/2
13 / 4 ≠ 5 / 2
11/14 × 7 = 11/2
11 / 2 = 11 / 2
3/35 × 7 = 3/5
3 / 5 = 3 / 5
5/7 × 7= 5
5 = 5
The equations that the number 7 makes true will be 11/14 × 7 = 11/2, 3/35 × 7 = 3/5, and 5/7 × 7= 5. Then the correct options are C, D, and E.

Given AB= 20, BV=12, VA=14 and SR is a mid segment, find the given lengths
Answers
Given:
AB= 20, BV=12, VA=14 and SR is a mid segment.
To find:
The lengths of SR and AR.
Solution:
SR is a mid segment. So, SR is parallel to the non-included side BV and the length of SR is half of BV.
[tex]SR=\dfrac{1}{2}BV[/tex]
[tex]SR=\dfrac{1}{2}(12)[/tex]
[tex]SR=6[/tex]
SR is a mid segment. So, it divides the included sides in two equal parts. It means R is the midpoint of VA.
[tex]AR=\dfrac{1}{2}VA[/tex]
[tex]AR=\dfrac{1}{2}(14)[/tex]
[tex]AR=7[/tex]
Therefore, the measure of SR is 6 units and the measure of AR is 7 units.

Onur is participating in a walkathon fundraiser. Two donors promised to donate money based on the total distance he walks. The money, A, in dollars, that he receives from the first donor given that he walks d kilometers is given by the formula A(d)=10d. The money, B, in dollars, that he receives from the second donor given that he walks d kilometers is given by the formula B(d)=2d+d^2.
Let T be the total money that Onur raises from those donors by walking d kilometers in the walkathon.
Write a formula for T(d), in terms of A(d) and B(d).
T(d)= ?
Write a formula for T(d), terms of d.
T(d)=?
Answers
Answer:
1. T(d) = A(d) + B(d)
2. T(d) = 12d + d²
Step-by-step explanation:
From the question given above, the following data were obtained:
A(d) = 10d
B(d) = 2d + d²
1. Determination of the formula of T(d) in terms of A(d) and B(d).
T(d) is the total money obtained. Thus,
T(d) = A(d) + B(d)
2. Determination of the formula of T(d) in terms of d.
A(d) = 10d
B(d) = 2d + d²
T(d) =?
T(d) = A(d) + B(d)
T(d) = 10d + 2d + d²
T(d) = 12d + d²
