Answer:
Step-by-step explanation:
So we have direct proportions here.
So
715=11
845=x
845*11/715
x=13
To check our work.
715/11=65
65*13=845.
Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/
So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.
Hope this helped, ask me if you have any questions.
En un triangulo ABC, el angulo B mide 64° y el angulo C mide 72°. La bisectriz interior CD corta a la altura BH y a la bisectriz BM en P y Q respectivamente. Hallar la diferencia entre el mayor y menor angulo del triangulo PBQ.
Answer:
The difference between the greatest and the smallest angle of the triangle PBQ is 98°.
Step-by-step explanation:
The question is:
In a triangle ABC, angle B measures 64 ° and angle C measures 72°. The inner bisector CD intersects the height BH and the bisector BM at P and Q respectively. Find the difference between the greatest and the smallest angle of the triangle PBQ.
Solution:
Consider the triangle ABC.
The measure of angle A is:
angle A + angle B + angle C = 180°
angle A = 180° - angle B - angle C
= 180° - 72° - 64°
= 44°
It is provided that CD and BM are bisectors.
That:
angle BCP = angle PCH = 36°
angle CBQ = angle QBD = 32°
angle BHC = 90°
Compute the measure of angle HBC as follows:
angle HBC = 180° - angle BHC + angle BCH
= 180° - 90° - 72°
= 18°
Compute the measure of angle BPC as follows:
angle BPC = 180° - angle PCB + angle CBP
= 180° - 18° - 36°
= 126°
Then the measure of angle BPQ will be:
angle BPQ = 180° - angle BPC
= 180° - 126°
angle BPQ = 54°
Compute the measure of angle PBQ as follows:
angle PBQ = angle B - angle QBD - angle HBC
= 64° - 32° - 18°
angle PBQ = 14°
Compute the measure of angle BQP as follows:
angle BQP = 180° - angle PBQ - angle BPQ
= 180° - 14° - 54°
angle BQP = 112°
So, the greatest and the smallest angle of the triangle PBQ are:
angle BQP = 112°
angle PBQ = 14°
Compute the difference:
d = angle BQP - angle PBQ
= 112° - 14°
= 98°
Thus, the difference between the greatest and the smallest angle of the triangle PBQ is 98°.
Solve for x: -2x + 5 < 7
Answer:
[tex]x>-1[/tex]
Step-by-step explanation:
Solve for x: [tex]-2x+5<7[/tex]
To solve this inequality, we must minus 5 from both of the sides.
[tex]-2x+5-5<7-5[/tex]
This equals
[tex]-2x<2[/tex]
Now we'll make this into a fraction and divide both sides by -2.
[tex]\frac{-2x}{-2} <\frac{2}{-2}[/tex]
After we divided, we got our answer.
[tex]x>-1[/tex]

make x the subject of 5(x-3) = y(4-3x)
Answer:-
5(x-3)=y(4-3x)
5x-15=4y-3xy
5x+3xy=4y+15
x(5+3y)=4y+15
x=>(4y+15)/(5+3y)
:)
Answer:
Step-by-step explanation:
5(x - 3) = y(4 - 3x)
Use distributive property
5*x - 5*3 = y*4 - y*3x
5x - 15 = 4y - 3xy
5x = 4y -3xy + 15
5x + 3xy = 4y +15
x(5 + 3y) = 4y +15
x = [tex]\frac{4y+15}{5+3y}[/tex]

Can someone answer this circle equation question? PLEASE SHOW STEPS
Answer:
A
Step-by-step explanation:
oh steps are here!
Answer:
a) 5
Step-by-step explanation:
2x² - 6x + 2y² + 2y = 45
Complete the square and get it in the form (x-a)² + (y -b)² = r²
2x² - 6x + 2y² + 2y = 45
Divide the equation by 2
x² - 3x + y² + y = 45/2
x² - 3x + ? + y² + y + ?? = 45/2
? -----> (x coefficient by 2)² = (3/2)² = 9/4
?? ----> (y coefficient by 2)² = (1/2)² = 1/4
Add (9/4) & (1/4) to both sides,
x² -3x +(9/4) + y² + y + (1/4) = (45/2)+ (9/4) + (1/4)
(x - 3/2)² + (y + 1/2)² = (90/4) + (9/4) + (1/4)
[tex](x-\frac{3}{2})^{2}+(y+\frac{1}{2})^{2}=\frac{90+9+1}{4}\\\\\\(x-\frac{3}{2})^{2}+(y+\frac{1}{2})^{2}=\frac{100}{4}\\\\\\(x-\frac{3}{2})^{2}+(y+\frac{1}{2})^{2}=25\\\\(x-\frac{3}{2})^{2}+(y+\frac{1}{2})^{2}=5^{2}[/tex]

Point U is on line segment TV. Given UV = 2, TU = 5x, and TV = 3x + 6,
determine the numerical length of TV.
Answer:
TV = 12
Step-by-step explanation:
TV = TU + UV
3x + 6 = 5x + 2
Shift the unknowns to the left, constants to the right.
3x - 5x = 2 - 6
-2x = -4
Divide both sides by -2.
x = 2
Substitute x = 2 into the equation for TV (3x + 6),
3x + 6
= 3(2) + 6
= 6 + 6
= 12
The numerical value of TV will be 12.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that Point U is a line segment TV. Given UV = 2, TU = 5x, and TV = 3x + 6.
The numerical value of TV will be calculated as below:-
TV = TU + UV
3x + 6 = 5x + 2
Shift the unknowns to the left, and constants to the right.
3x - 5x = 2 - 6
-2x = -4
Divide both sides by -2.
x = 2
Substitute x = 2 into the equation for TV (3x + 6),
TV = 3x + 6
TV = 3(2) + 6
TV = 6 + 6
TV = 12
Therefore, the numerical value of TV will be 12.

How would I create a graph for this equation? The equation is c=4.95+3.99b
Answer:
plot two points and draw a line through them
Step-by-step explanation:
The graph is created for this the same way it is for any function: find some points on the graph, plot them, and draw an appropriate curve through them.
Since this is a linear equation, the graph is a straight line. Only two points are needed to allow you to plot the entire line.
For b=0, the point is (b, C) = (0, 4.95)
For b=5, the point is (b, C) = (5, 24.90)
The graph might look like the attached.
_____
For b=5, the equation gives ...
C = 4.95 +3.99(5) = 4.95 +19.95 = 24.90

a college admissions office collects data from each incoming freshman on several quantitative variables distance from their home to campus, number of siblings, how many books they have read in the past month and how long it took them to complete an online survey. classify each variable as discrete or continuous
Answer:
1) Distance from their home to campus → Continuous
2) The number of siblings → Discrete
3) How many books they have read in the past month → Discrete
4) How long it took them to complete an online survey → Continuous
Step-by-step explanation:
A discrete variable is a variable with a constant value which is found to be accurate by counting of articles in the subject.
Examples of discrete variables are the amount of money in a person's pocket, the number of people in a bus
A continuous variable is one that is a variable that if it is possible for the variable to have values between two values, then the variable can have any of the values in between the two values
Example of a continuous variable are
The Height of people within a building
The distance traveled to a location.
Therefore, we have the following classification of the data is given as follows;
1) from their home to campus is a Continuous variable
2) The number of siblings is a Discrete variable
3) How many books they have read in the past month is a Discrete variable
4) How long it took them to complete an online survey is a Continuous variable.
