Find angle RUS PLEASE HELP ME
Answer:
m∠RUS = 37°
Step-by-step explanation:
In a rhombus, diagonals bisect angles. In other words,
m∠RUS = m∠SUT
Substitute and solve.
10x - 23 = 3x + 19
7x = 42
x = 6
Substitute x = 6 into the equation given for m∠RUS
m∠RUS = (10x-23)
m∠RUS = 37°
match each equation to an equivalent equation written in slope intercept form
Answer:
2x+y=3 --> y= -2x+3
2y-6=x --> y= 1/2x+3
x-3y=-6 --> y= 1/3x+2
-x+1/2y=3 --> y= 2x+6
Step-by-step explanation:
i hope this helps :)
The solution to the system of equations is
2x + y = 3 ; y = -2x + 3
2y - 6 = x ; y = ( 1/2 )x + 3
x - 3y = -6 ; y = ( 1/3 )x + 2
-x + ( 1/2 )y = 3 ; y = 2x + 6
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
a)
Let the equation be 2x + y = 3
Subtracting 2x on both sides of the equation , we get
y = 3 - 2x
So , the equation in slope intercept form is y = 3 - 2x
b)
Let the equation be 2y - 6 = x
Adding 6 on both sides of the equation , we get
2y = x + 6
Divide by 2 on both sides of the equation , we get
y = ( 1/2 )x + 3
So , the equation in slope intercept form is y = ( 1/2 )x + 3
c)
Let the equation be x - 3y = -6
Adding 3y on both sides of the equation , we get
x = 3y - 6
Adding 6 on both sides of the equation , we get
3y = x + 6
Divide by 3 on both sides of the equation , we get
y = ( 1/3 )x + 2
So , the equation in slope intercept form is y = ( 1/3 )x + 2
d)
Let the equation be -x + ( 1/2 )y = 3
Adding x on both sides of the equation , we get
( 1/2 )y = 3 + x
Multiply by 2 on both sides of the equation , we get
y = 2x + 6
So , the equation in slope intercept form is y = 2x + 6
Hence , the equations are solved

Use the parabola tool to graph the quadratic function y=-1? - 2.0 +8
Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.
Answer:
see explanation
Step-by-step explanation:
I don't have graphing facilities but can give you the vertex and 1 other point.
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
y = - x² - 2x + 8 ← is in standard form
with a = - 1 and b = - 2 , then
x = - [tex]\frac{-2}{-2}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y
y = - (- 1)² - 2(- 1) + 8 = - 1 + 2 + 8 = 9
vertex = (- 1, 9 )
To obtain another point substitute any value for x into the equation
x = 0 : y = 0 - 0 + 8 , then (0, 8 ) is a point on the graph
x = 2 : y = - (2)² - 2(2) + 8 = - 4 - 4 + 8 = 0 then (2, 0 ) is a point on the graph

A cooking school is teaching students how to make pasta noodles. The line plot displays how much flour each student used. How many total cups of flour did the students use to make the pasta?
Answer:
[tex]Total = 11\frac{1}{8}\ cups[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
Total number of cups used
The number of dot on each dataset represent the number of student
So, to get the total number of cups, we simply add the product of the number of cups and the number of student for each data item
So, we have:
[tex]Total = \frac{1}{8} * 6 + \frac{1}{4} * 5 + \frac{3}{8} * 2 + \frac{1}{2}*0 + \frac{5}{8} * 4 + \frac{3}{4} * 2 + \frac{7}{8} * 5[/tex]
[tex]Total = \frac{6}{8} + \frac{5}{4} + \frac{6}{8} + 0+ \frac{20}{8} + \frac{6}{4} + \frac{35}{8}[/tex]
Solve
[tex]Total = \frac{6+10+6+0+20+12+35}{8}[/tex]
[tex]Total = \frac{89}{8}[/tex]
[tex]Total = 11\frac{1}{8}\ cups[/tex]
An arithmetic progression consists of 37 terms. The sum of the first 3 terms of
it is 12 and the sum of its last-3 terms is 318, then find the first and last terms
of the progression.
Answers:
First term = 1Last term (37th term) = 109=======================================================
Explanation:
a1 = first term
a2 = second term
a3 = third term
and so on, until we reach a37 to represent the 37th term
We don't know the first term, but we'll call it x for now. We'll also let d be the difference between each adjacent term, aka the common difference.
Meaning that,
a1 = xa2 = a1+d = x+da3 = a2+d = (x+d)+d = x+2da4 = a3+d = (x+2d)+d = x+3dand so on, until,
a35 = x+34da36 = x+35da37 = x+36d---------------------
Add up the first three terms (a1 through a3) and set the sum equal to 12
Then do a bit of algebra to get
a1+a2+a3 = 12
(x)+(x+d)+(x+2d) = 12
3x+3d = 12
3(x+d) = 12
x+d = 12/3
x+d = 4
x = 4-d
Do the same for the last three terms, but the sum here is 318
a35+a36+a37 = 318
(x+34d)+(x+35d)+(x+36d) = 318
3x+105d = 318
3(x) + 105d = 318
3(4-d)+105d = 318 .... replace x with 4-d; isolate d
12-3d+105d = 318
102d+12 = 318
102d = 318-12
102d = 306
d = 306/102
d = 3
The common difference is 3. It means each term is increasing by 3.
Use this value of d to find x
x = 4-d
x = 4-3
x = 1
The first term is 1. That makes the second term x+d = 1+3 = 4, then the third term is x+2d = 1+2*3 = 7, and so on.
The sum of the first three terms is 1+4+7 = 12. That helps partly confirm the answer.
Also we have,
a35 = x+34d = 1+34(3) = 103a36 = x+35d = 1+35(3) = 106a37 = x+36d = 1+36(3) = 109 is the last term (37th term)Or you could note that the 35th term is 103, and then you increase by 3 each time to get the remaining two terms.
The last part of the confirmation is adding up those three last terms: 103+106+109 = 318, so the answer is fully verified at this point.
Side note: An arithmetic sequence never ends. There technically is no "last term"; however, since we're confined to focusing on these specific 37 terms, we can get away with using the phrasing.

also, make a table to show the sample space and find the number of outcomes.
Answer:
12.5% or .125
Step-by-step explanation:
4 options for the spinner all with equal probability, chance of spinning any number is 1/4; 2 options for the coin of equal probability so any side has a probability of 1/2. 1/4*1/2=1/8 chance; this is equal to 12.5% or .125.
there are 8 possible outcomes; 4 with spinner, 2 with coin, 4*2=8.

The best player on a basketball team makes 85% of all free throws. The second-best player makes
75% of all free throws. The third-best player makes 70% of all free throws. Based on their
experimental probabilities, estimate the number of free throws each player will make in his or her
next 40 attempts. Explain.
For the best player, one equation that gives the estimated number of free throws is____. The best player will make about______.
free throws.
Answer:
i. Estimated number of free throws of the best player = 0.85 * 40
ii. 34 free throws
Step-by-step explanation:
Percentage of free throws made by the best player = 85%
Percentage of free throws made by the second best player = 75%
Percentage of free throws made by the third best player = 70%
Therefore, for 40 attempts;
i. Estimated number of free throws made by the best player = 85% x 40
= 0.85 x 40
= 34
ii. Estimated number of free throws made by the second best player = 75%x 40
= 0.75 x 40
= 30
iii. Estimated number of free throws made by the third best player = 70% x 40
= 0.70 x 40
= 28
Thus, the equation that gives the estimated number of free throws is 0.85 * 40.
The best player will make about 34 free throws.

Derrick needs to figure out how he’s doing on his test scores so far this year. You can help by calculating the mean and the median to get an overall picture of his scores. Below are all of his scores:
25, 40, 68, 85, 95, 98, 70, 78, 85, 100
Answer:
Mean = 74.4
Median = 81.5
Step-by-step explanation:
25, 40, 68, 85, 95, 98, 70, 78, 85, 100
Mean = Sum of values / Number of values
Number of values = 10
= 25 + 40 + 68 + 70 + 78 + 85 + 85 + 95 + 98 + 100/10
= 744/10
= 74.4
Median
Rearranging the given data
= 25, 40 ,68 ,70 ,78 ,85 ,85 , 95 ,98 ,100
Formula for median = 1/2(n + 1)th value
n = 10
Hence
1/2(10 + 1)th value
1/2(11)th value
= 5.5 th value
This fall between the 5th and 6th value
5th value = 78
6th value = 85
Hence: 78 + 85/2
= 163 / 2
= 81.5
