Answer: A. mB = 24.8ᴼ
Step-by-step explanation:
A and B are complementary angles, which means they add to equal 90ᴼ.
To find mB, subtract mA from 90
90 - 65.2 = 24.8
The bisector of the base angles Q and R of an equilateral triangle PQR meet at S. ST and SM are drawn parallel to the sides PQ and PR. Show that QT=TM=MR
Answer:
From TM = MS, MS = MR, and TM = MR
QT = TM = MR Transitive property
Step-by-step explanation:
ΔPQR is an equilateral triangle Given
∠PQR = ∠RPQ = ∠PRQ = 60° Definition of equilateral triangle
∠PQR = ∠SQT + ∠SQP = 60° Addition property of angles
∠PRQ = ∠SRM + ∠SRP = 60° Addition property of angles
In triangle PQR, ∠SQT = ∠SQP = 30° = ∠SRM = ∠SRP Angles bisected by angle bisector
∠STM = ∠PQR - 60° Angle of same side of two parallel lines crossing the same transversal
∠PRQ = ∠SMT = 60° Angle of same side of two parallel lines crossing the same transversal
∠MST = 180 - ∠SMT - ∠STM = 180 - 60 - 60 = 60°
∠MST = ∠SMT = ∠STM = 60°, ΔMST is an equilateral triangle, all angles equal
ST = MS = TM definition of equilateral triangle
∠STQ = 180 - ∠STM = 180° - 60° = 120° (∠STQ and ∠STM are supplementary angles)
∠QST = 180 - ∠SQT - ∠STQ = 180 - 30 - 120 = 30 (Interior angles in the same triangle)
ΔQTS is an isosceles triangle, base angles are equal
∴ ST = QT Definition of equilateral triangle
Similarly
∠SMR = 180 - ∠SMT = 180° - 60° = 120° ∠SMR and ∠SMT are supplementary angles
∠MSR = 180 - ∠SRM - ∠SMR = 180 - 30 - 120 = 30 (Angles in the same triangle)
ΔRMS is an isosceles triangle, base angles are equal
∴ MS = MR Definition of equilateral triangle
Since ST = QT, and, ST = TM, QT = TM Transitive property
Also since TM = MS, and MS = MR, TM = MR Transitive property
Therefore;
QT = TM = MR Transitive property

The correct option is C.
a kennel has40 dogs in total , some are puppies and some are adults dogs . the ratio of puppies to adult dogs is 1:4 how many puppies are there
Answer:
8 puppies
Step-by-step explanation:
Total = 40
Ratio = 1:4
Total Parts = 4+1 = 5
Divide this from the total
=> 40/5 = 8
Now, Multiply the result with the ratios:
=> 4 * 8 = 32
=> 1 * 8 = 8
Answer: total number of puppies:40
Ratio of puppies to adults;1:4
1x+4x=40… 1x puppies
4x adult dogs
5x=40:x=40/5=8
No. Of puppies=1*8(x=8)
No.of adult dogs=4*8:32
PLEASE HELP Which of the following types of data are likely to be normally distributed? Select all that apply
Answer: the correct answer is D and E
Step-by-step explanation:
Based only on the given information, it is guaranteed that AB is perpendicular to CD. True or false
Answer:
true
Step-by-step explanation:
because CD divided AB into equal halves, so they are of course perpendicular.
Answer:
Step-by-step explanation:
This is definitely true. AC is congruent to BD, and by the Isosceles Triangle Theorem, if this congruency is true, then the angles across from these congruent sides are also congruent. This means that angle ACD is congruent to angle BCD. That makes CD a bisector of angle ACB; it also makes CD a bisector of side AB. The definition of a perpendicular bisector is that the segment splits its angle in half (and it does) and that it splits the side it goes through in half (which it does). This makes CD, in a nutshell, the perpendicular bisector of AB (which also means that CD is perpendicular to AB).

Estimate the answer by rounding the percent to the nearest ten and the second number to the nearest thousand. 2828% of 8102
Answer:
First one that is rounded off near 100 is .29 and second one that is rounded off near 1000 is 8102
Step-by-step explanation:
Rounding the percent to the nearest ten and the second number to the nearest thousand gives the estimated answer is 2400.
To estimate the answer, we will round the percent to the nearest ten and the second number to the nearest thousand.
28% of 8102 can be approximated as follows:
Step 1: Round 28% to the nearest ten, which is 30%.
Step 2: Round 8102 to the nearest thousand, which is 8000.
Step 3: Calculate 30% of 8000.
30% of 8000 = 0.30 * 8000 = 2400.
Rounding to the nearest ten and thousand helps simplify calculations while still providing a reasonably accurate estimate. However, it's essential to remember that this is an approximation and might not be as precise as calculating the exact value. Rounding introduces some degree of error, but for quick estimations, it can be a useful technique.

Using the ratio flats : bungalows = 10 : 3
Given there are 30 bungalows then dividing by 3 gives the value of one part of the ratio.
30 ÷ 3 = 10 ← value of 1 part of the ratio, thus
10 parts = 10 × 10 = 100 ← number of flats
Using the ratio houses : flats = 9 : 5
The number of flats = 100 thus dividing by 5 gives
100 ÷ 5 = 20 ← value of 1 part of the ratio, thus
9 parts = 9 × 20 = 180 ← number of houses

Solar energy is considered by many to be the energy of the future. A recent survey was taken to compare the cost of solar energy to the cost of gas or electric energy. Results of the survey revealed that the distribution of the amount of the monthly utility bill of a 3-bedroom house using gas or electric energy had a mean of $120 and a standard deviation of $11. If the distribution can be considered bell shaped, what percentage of homes will have a monthly utility bill of more than $109? Group of answer choices approximately 16% approximately 32% approximately 84% approximately 95%
Answer:
The answer is 132
Step-by-step explanation:
The percentage of homes will have a monthly utility bill of more than $109 is approximately 84%
How is standard deviation calculated?Suppose that the considered data set is x bar.
Then, its standard deviation is the positive square root of the variance of this data set. Variance of data set is the sum of squared differences of the data values from its mean to the total count of data values.
We are given that Mean, m = $92
Standard deviation, s = $13
Now, we have to find calculate percentage of homes will have a monthly utility bill of more than $79 i.e P(X > 79)
Also, P( X > 79) = 1 - P( X < 79)
Z-score for (X = 79 )
Z = -1
From the standard Z value vs P table, we have;
P( Z < -1 ) = 0.1587
Thus,
P( X < 79) = P( Z < -1 ) = 0.1587
therefore,
P(X > 79) = 1 - 0.1587
P(X > 79) = 0.8413
= 0.8413 × 100%
= 84.13%
Hence, the option d) is approximately 84%

Significant figure can be defined in mathematics as the number of integers or digits in a number that tells us how significant and accurate the number is.
Rounding to 1 significant figure, 346 x 904 is 300000
When rounding a number to significant figures, the following rules are important.
Digits with no zeros in them are always significant Zeros between digits with no zeros in them are always significant The zero at the beginning of a number is not insignificant.
346 multiplied by 904 is calculated as:
