In parallelogram ABCD if m
Answer:
145 degrees
Step-by-step explanation:
All angles in a parallelogram always add up to 360 degrees when added together.
And all angles are the same as the angle adjacent to them.
Since we already know that angle DAB is 35, then the adjacent angle BCD, is also 35.
And since we know that all the angles add up to 360, we just gotta do the math.
35 + 35 = 70 and when you subtract 70 from 360 you get 290. Now all you have to do is divide 290 by 2, and you get 145, which is also the same as angle ABC since they are adjacent to each other.

Answer:
1) glazed = 48 people
Chocolate = 72 people
Jelly = 24 people
Coconut = 16 people
2)9th grade = 219 students
10th grade = 167 students
11th grade = 147 students
12th grade = 151 students
Step-by-step explanation:
We are solving the examples;
1) We are told that there are 20 students in Kayla's first period class.
No. that preferred glazed donuts = 6
No. that preferred chocolate donuts = 9
No. that preferred jelly donut = 3
Number that preferred coconut donut = 2
Now,there are a total of 160 students in the entire grade. So to find the Number of students in this entire grade that will each prefer the types of donuts listed above, we will solve as;
For glazed donuts; 6/20 × 160 = 48 people
For chocolate donuts; 9/20 × 160 = 72 people
For jelly donut; 3/20 × 160 = 24 people
For coconut donut; 2/20 × 160 = 16 people
2) Total number of students is;
9th grade = 300 students
10th grade = 275 students
11th grade = 250 students
12th grade = 280 students
73% of 9th grade prefer valorant. Thus;
73% × 300 ≈ 219 students
61% of 10th grade prefer valorant. Thus;
61% × 275 ≈ 167 students
59% of 11th grade prefer valorant. Thus;
59% × 250 ≈ 147 students
54% of 12th grade prefer valorant. Thus;
54% × 280 ≈ 151 students
the average of nine number is 16. the average of 4 of these number is 11. what is the average of the other five number ?
Answer:
11
Step-by-step explanation:
We know formula to find average is,
Average=
Numberofnumbers
Sumofnumbers
Since the average of 10, so the sum of numbers is 5×10=50
As the fifth number is given 6, so rest 4 numbers will be = 50−6=44
Average of first four numbers will be Average=

solve for t in d =rt if d =57 and r =30. t=
57 = 30 × t
t = 57/30
t = 19 × 3 / 10 × 3
t = 19/10
t = 1.9
Answer:
t = 1.9
Step-by-step explanation:
Given
d = rt
Substitute d = 57 and r = 30 into the equation
57 = 30t ( divide both sides by 30 )
[tex]\frac{57}{30}[/tex] = t , that is
t = 1.9

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. What is the probability that a randomly chosen person's IQ score will be between 101 and 134, to the nearest thousandth
Answer:
Step-by-step explanation:
IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. What is the probability that a randomly chosen person's IQ score will be between 101 and 134, to the nearest thousandth
z = (x-μ)/σ, where x is the raw score,
μ is the population mean = 100
σ is the population standard deviation = 15
For x = 101
z = 101 - 100/15
z = 0.066667
Probability value from Z-Table:
P(x = 101) = 0.52658
For x = 134
z = 134 - 100/15
z = 2.26667
Probability value from Z-Table:
P(x= 134) = 0.98829
Therefore,

The temperature in Sam's home varies sinusoidal over time. Given the equation T = 4 cos(30(t − 8)) + 16 describes the temperature of the house in degrees celsius in terms of the number of hours since 12 midnight.
Answer:
The temperature is: 14.5 degrees
Step-by-step explanation:
Given
[tex]T = 4 \cos(30(t - 8)) + 16[/tex]
Required
The temperature at 4:15
We have:
[tex]t = 4:15[/tex]
Convert to hours
[tex]t = 4+\frac{15}{60}[/tex]
[tex]t = 4+0.25[/tex]
[tex]t = 4.25[/tex]
So:
[tex]T = 4 \cos(30(t - 8)) + 16[/tex]
[tex]T = 4 \cos(30(4.25 - 8)) + 16[/tex]
[tex]T = 4 \cos(30(-3.75)) + 16[/tex]
Open bracket
[tex]T = 4 \cos(-112.5) + 16[/tex]
[tex]T = 4 *-0.3826 + 16[/tex]
[tex]T = -1.5304 + 16[/tex]
[tex]T = 14.4696[/tex]
Approximate
[tex]T = 14.5^o[/tex]

Determine whether the side lengths could represent a right triangle.
14, 21, 25
Answer:
No
Step-by-step explanation:
Using the given values, 25 is the largest value, so if this were a right triangle, it would be the hypotenuse.
Using Pythagoras' theorem: For this triangle to be a right triangle, √(21² + 14²) must be equal to 25.
√(21² + 14²) = 25.239 (5sf) ≠ 25
Hence the triangle formed is not right.

The circumference of a circle is 16 ft.
The radius is ?
Answer:
8/pi or approximately 2.55 ft
Step-by-step explanation:
The formula for the circumference is
C = 2 * pi *r
16 = 2 * pi *r
Divide each side by 2 pi
16 / ( 2 pi) = 2 * pi * r/ ( 2 pi)
8 / pi = r
Using 3.14 for pi
8 / 3.14 = r
2.54777 = r
2.55 =r
Answer:
Radius ≈ 2.55 ft.
Step-by-step explanation:
GIVEN :-
Circumference of circle = 16 ft.TO FIND :-
Radius of the circleFORMULAE TO KNOW BEFORE SOLVING :-
For a circle with radius 'r' & circumference 'c' ,
[tex]r = \frac{c}{2\pi }[/tex]
SOLUTION :-
[tex]Radius = \frac{Circumference}{2\pi } = \frac{16}{2\pi } = \frac{8}{\pi } = 2.55 ft. (appx)[/tex]

4. (-4,-5), 8
5. (7,3), 12
6. x^2 + (y+5)^2 = 49
7. (x-6)^2 + (y+1)^2 = 144
8. (x+2)^2 + (y-3)^2 = 16
9. (0-0)^2 + (7-3)^2 = r^2
0 + 16 = r^2
=> r = 4
Step-by-step explanation:
remember, the general equating of a circle is
(x-h)^2 + (y-k)^2 = r^2
El agua de un manantial se conduce hasta unos depósitos cilíndricos que miden 12 m de radio de la base y 20 m de altura. Luego se embotella en bidones de 2.5 litros. ¿Cuántos envases se llenan con cada depósito?
Answer:
Con cada depósito se pueden llenar 3,617.28 envases.
Step-by-step explanation:
Dado que el agua de un manantial se conduce hasta unos depósitos cilíndricos que miden 12 m de radio de la base y 20 m de altura, y luego se embotella en bidones de 2.5 litros, para determinar cuántos envases se llenan con cada depósito se debe realizar el siguiente cálculo, sabiendo que el volumen de un cilindro se obtiene multiplicando pi por el radio del cilindro al cuadrado por su altura:
3.14 x (12x12) x 20 = X
3.14 x 144 x 20 = X
452.16 x 20 = X
9,043.2 = X
9,043.2 / 2.5 = X
3,617.28 = X
Por lo tanto, con cada depósito se pueden llenar 3,617.28 envases.

Answer:
z = 30; obtuse isosceles triangle
Step-by-step explanation:
4z + z + 30 = 180
5z + 30 = 180
5z (+ 30 - 30) = 180 - 30
5z = 150
5z/5 = 150/5
z = 30
Since z = 30, and 30 = 30, two angles are congruent to each other and there is only one obtuse angle. Therefore, this is an obtuse isosceles triangle.
Answer:
30, obtuse isosceles
Step-by-step explanation:
Tow sides are the same making it an isosceles triangle. This requires two of the same sides and two of the same angles. This means that z is the sameas 30 degrees.
A statistics student is studying if there is a relationship between the price of a used car and the number of miles it has been driven.

Answer:
y = - 0.181x + 24157.2
Step-by-step explanation:
Equation of the regression line is given from. The table by the Coefficient of the predictor, x variable and the intercept value :
The predictor here is mileage, which has a Coefficient of - 0.181
The constant value = intercept 24157.2
The regression equation is written in the form :
y = mx + c ; m = slope = Coefficient of predictor, ; x = predictor,
