Answer:
x=10.4
Step-by-step explanation:
well 20*5=what? 20*5=100 but then x would have to be a decimal. not a tough one though.
10*x (x being 10) 10*10 would be 100 but then you would have to subtract 4 from it. it's easy. 10 *10.4 is 104.
x would = 10.4 to get this result

Answer:
First, we can find the least common denominator for 8 and 3 which is 24.
5/8 = 15/24
1/3 = 8/24
Then we can divide 15/24 by 8/24 which is 2 1/4.
If we then do 16 divided by 2 1/4 we get 7 1/9
Answer = 7 1/9
Step-by-step explanation:
in which groupthe given angels(160,20)will fall,if their sum is 180
Answer:
Supplementary angles.
Step-by-step explanation:
We can define two big groups of pairs of angles.
Complementary and supplementary angles.
Two angles are complementary if the sum of their measures is equal to 90°
Two angles are supplementary if the sum of their measures is equal to 180°
Here, we have the angles 160° and 20°, and we know that their sum is 180°
Then we can conclude that the given angles fall in the group of the supplementary angles.

Marsha likes to take photos with her new camera.She already has 1427 photos. She just bought her camera 15 days ago and took pictures everyday.Approximately how many pictures did she take each day?
Answer:
About 95
Step-by-step explanation:
If she bought her camera 15 days ago, then you just divide 1427 by 15. You can't take parts of pictures, so it has to be a whole number, so you round.
Answer:
95.1333333333 you should probably round it but thats how many photos she took each day
Step-by-step explanation:
1427/15= photos taken each day
What is the measure of ∠x?
Answer:
angle x= 38 degrees
Step-by-step explanation:
Supplementary angles are equal to 180 degrees. We know angle y is equal to 142 degrees. Therefore, the equation is 180-142 which is equal to 38. Angle x is equal to 38 degrees.

I need simple working out thank you for anyone helping me
Answer:
Step-by-step explanation:
we know that the triangle to the center is an isosceles, so the two angle on the circle of that triangle are the same. both 41, so 41*2 =82
all the way around that isosceles triangle is 180 so
180-82 = 98
the angle at O is 98°
the arc BC spans 98°
angle 'a' is 1/2(98°)
a = 49°
En el club de teatro asistieron 15 alumnos a clases .Si en total son 21 ¿ cual es la razon entre el total de alumnos y los ausentes
Answer:
La razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]
Step-by-step explanation:
En el club de teatro asistieron 15 alumnos a clases. En total, son 21 alumnos. Entonces la cantidad de alumnos ausentes se calcula como la diferencia entre la cantidad total de alumnos y la cantidad de asistentes, esto es:
21 alumnos - 15 alumnos= 6 alumnos
La cantidad de alumnos ausentes es 6.
La razón es la comparación de dos cantidades y se mide como el cociente entre dos números o cantidades comparables entre sí, que se expresa como una fracción. Es decir, la razón entre 2 números a y b es el cociente [tex]\frac{a}{b}[/tex].
Entonces, la razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Selecting two marbles from a bag containing the numbers 2,4,6,8,10,12 (with replacement) what is the probability of selecting two numbers less than 10 ?
Given:
A bag containing the numbers 2,4,6,8,10,12.
To find:
The probability of selecting two numbers less than 10.
Solution:
We have,
Total numbers = 6
Numbers less than 10 are 2,4,6,8.
Numbers less than 10 = 4
Probability of getting a number less than 10 is:
[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]
[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]
[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]
We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.
Probability of selecting two numbers less than 10 is:
[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]
[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]
[tex]\text{Required probability}=\dfrac{4}{9}[/tex]
Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].

y=-6x+2
Rewrite in standard form
Answer:
0.000002
Step-by-step explanation:
since its -6+2 you need to move the decimal place in 2, 6 places foward. So the number would go from 2 to 0.000002.
Answer:
6x+y=2

Goran has scored 38, 27, 23, 19, and 26 points in his five basketball games so far. How many points does he need to score in his next game so that his average (mean) is 27 points per game?
Answer:
29
Step-by-step explanation:
(38+27+23+19+26+X)/6=27
133 + X = 162
X = 29
Answer:
29
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be the score required to give a mean of 27 in the 6 games
[tex]\frac{38+27+23+19+26+x}{6}[/tex] = 27 ( multiply both sides by 6 )
133 + x = 162 ( subtract 133 from both sides )
x = 29
He requires to score 29 points
Explain how you would find the perimeter of quadrilateral WXYZ and find it.

I would find the distance of each of the 4 sides and then add them up. There is no picture or numbers to add up for your question.
Answer:
The formula to find the perimeter of the quadrilateral
= sum of the length of all the four sides.
write the slope-intercept form of the equation of the line through the given points.
Answer:
y = 4x - 7 (Answer C)
Step-by-step explanation:
First find the slope of this line. Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.
Thus, the slope, m, is
m = rise / run = 4/1, or m = 4.
Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:
y - k = m(x - h) becomes y - 1 = 4(x - 2)
Solving for y, we get: y = 4x - 8 + 1, or y = 4x - 7 (Answer C)
Three consecutive integers add up to 51. What are these integers
Let the three consecutive integers be x, x+1 and x+2.
According to the question, x+x+1+x+2=51
=>3x+3=51
=>3x+3-3=51-3
=>3x=48
=>x=16
Hence, first integer = 16,
second integer = 16 + 1 = 17 and
third integer = 16 + 2 = 18.

What is the surface area of a cylinder with a height of 20 meters and a diameter of 10 meters? O A) 1884 m2 OB) 863 m2 OC) 353.25 m2 OD) 785 m2
Answer:
785
Step-by-step explanation:
did the math in a calculator I got yoy
Answer:
D. 785
Step-by-step explanation:
the formula to find the surface area of a cylinder is A=2πrh+2πr^2
the diameter is a straight line through the center of a figure so half of that would be the radius and our diameter is 10 so the radius is 5
our height is 20 so now we put it into the equation it will look like this
2·π·5·20+2·π·5^2
once you do the math you will get 785.39816

Given:
ST || RU
To find:
The measure of QS.
Solution:
In triangle QRU and QST,
[tex]\angle RQU\cong \angle SQT[/tex] [Common angle]
[tex]\angle QRU\cong \angle QST[/tex] [Corresponding angle]
[tex]\triangle RQU\sim \triangle SQT[/tex] [AA property of similarity]
The corresponding sides of similar triangles are proportional.
[tex]\dfrac{QR}{QS}=\dfrac{QU}{QT}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{25}{25+50}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{25}{75}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{1}{3}[/tex]
On cross multiplication, we get
[tex]3(23)=1(QS)[/tex]
[tex]69=QS[/tex]
Therefore, the measure of QS is 69.

A = {prime numbers between 4 and 25} B = {odd numbers less than 16} List the outcomes of A, B and explain? List the outcomes of A, B and explain?
The image below better explains it. Thank you.
Answer:
A u B = {1,3,5,7,9,11,13,15,17,19,23}
A n B = {5,7,11,13}
Step-by-step explanation:
The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23
A = {5, 7,11, 13, 17, 19,23}
B are odd numbers less than 16
B = {1, 3 , 5,7,9,11,13,15}
The union of both is the list of all values present in both sets without repeating;
A u B = {1, 3, 5,7,9,11,13,15,17,19,23}
A n B is the set that contains values that are present in both sets
A n B = {5,7,11 , 13}

Answer:
cos A = 24/51
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Cos theta = adj side/ hypotenuse
cos A = 24/51
Step-by-step explanation:
We know that cosA=Base/hypontenuse
➡CosA=24/51
Reason :-This is a right angle triangle
Cos theta=Base/hypontenuse
