Which figure has exactly one line of symmetry? A rhombus, pentagon, rectangle and triangle are shown. A. Rhombus B. Pentagon C. Rectangle D. Triangle
Answers
Answer: The figure that has exactly one line of symmetry is B. Pentagon.
Step-by-step explanation: A line of symmetry is a line that divides a figure into two congruent halves that are mirror images of each other. A figure can have zero, one, or more lines of symmetry depending on its shape and orientation. To find the lines of symmetry of a figure, we can use a paper folding method or a reflection test. A paper folding method involves folding the figure along a line and checking if the two halves match up exactly. A reflection test involves reflecting the figure over a line and checking if the image coincides with the original figure.
Using either method, we can see that:
A. Rhombus has two lines of symmetry: one diagonal and one vertical.
C. Rectangle has two lines of symmetry: one horizontal and one vertical.
D. Triangle has either zero or three lines of symmetry depending on the type of triangle. An equilateral triangle has three lines of symmetry: one vertical and two bisecting the angles. An isosceles triangle has one line of symmetry: the perpendicular bisector of the base. A scalene triangle has no lines of symmetry.
B. Pentagon has either zero or five lines of symmetry depending on the type of pentagon. A regular pentagon has five lines of symmetry: each passing through a vertex and the midpoint of the opposite side. An irregular pentagon has no lines of symmetry.
Therefore, the only figure that has exactly one line of symmetry is B. Pentagon, but only if it is an isosceles pentagon.

Find the length of the missing side in the figure below. a = _______ cm.
a right triangle with short side labelled a, long side labeled 4.7 cm and hypotenuse labelled 7.1 cm. PLEEZE! IM DESPERATE!
Answers
Answer:
\( \frac{2 \sqrt{177} }{5} \)
or
5.32cm correct to 2 decimal places
Step-by-step explanation:
This is a right angled triangle from what I know so we have to apply pythagoras theorem.
\( {7.1}^{2} = {a}^{2} + {4.7}^{2} \)
we need to rearrange this to find a²
\( {a}^{2} = {7.1}^{2} - {4.7}^{2} \)
\(a = \sqrt{ \frac{708}{25} } \)
This can either be written as a fraction or decimal.
\(a = \frac{2 \sqrt{177} }{5} \)
OR
\(a = 5.32\)
correct to 2 decimal places

He did not multiply the numerator and denominator by the correct number to equal 1,500.

Answer:
36b - 2c - 6 / 3
Step-by-step explanation:
16b - 1 × 2/3 (c + 3) - 4b
Multiply the numbers:
1) 16b - 1 ×2/3 (c + 3) - 4b
16b - 2/3 (c + 3) - 4b
Combine multiplied terms into a single fraction:
2) 16b - 2/3 (c + 3) - 4b
16b + -2 ( c + 3) / 3 -4b
Distribute:
3) 16b + -2 (c + 3) / 3 -4b
16b + -2c - 6 / 3 -4b
Combine like terms:
4) 16b + -2c -6 / 3 -4b
12b + -2c -6 / 3
Find a Common Denominator:
5) 12b + -2c -6 / 3
3 × 12b / 3 + -2c - 6 / 3
Combine fractions with a Common Denominator:
6) 3 × 12b / 3 + -2c - 6 / 3
3 × 12b - 2c - 6 / 3
Multiply the numbers:
7) 3 × 12b - 2c - 6 / 3
36b - 2c - 6 / 3

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
