[tex]\bf Step-by-step~explanation:[/tex]
We are given that BA is perpendicular to BD, so that must mean that m∠ABD is a right angle, or 90º. This means: (8x - 10) + (4x + 52) = 90º, since both of the angles add up to become a right angle. We have to solve for x in order to find m∠CBD.
PART 1
[tex]\bf Step~1:[/tex]
Equation: (8x - 10) + (4x + 52) = 90
Let's add the like values together first.
[tex]\bf 8x+4x=12x\\-10+52 = 42[/tex]
[tex]\bf 12x+42=90[/tex]
[tex]\bf Step~2:[/tex]
Let's subtract 42 from both sides of the equation to isolate the variable we are solving for, x. Our goal is to isolate it completely to get a value that is equal to x.
[tex]\bf12x+42(-42)=90(=42)\\12x=48[/tex]
[tex]\bf Step~3:[/tex]
Divide both sides by 12 to get our final answer for x.
[tex]\bf\frac{12x}{12} =x\\\\\frac{48}{12}= 4\\\\x=4[/tex]
PART 2
Now that we have x, we simply plug it into our equation for m∠CBD.
[tex]\bf Step~1:[/tex]
[tex]\bf4x+52\\4(4)+52[/tex]
[tex]\bf Step~2:[/tex]
Multiply 4 and add 52.
[tex]\bf 4*4=16\\16+52=68[/tex]
[tex]\large\boxed{\bf Our~final~answer: mCBD=68}[/tex]

the angles of a qaudileteral are x,2x,100 and 110 degress find the value of 2x
Answers
Step-by-step explanation:
Hey there!!!!
We generally sum up all the angles to get 360° as per given in our question.
Here, in your question, we have values as,
x, 2x, 100°, 110°.
(We have 360° as the sum quadrilateral).
So, x° + 2x° + 100°+110° = 360°
3x°+210°= 360°
3x° = 360° - 210°
or, 3x° = 150°
[tex]x = \frac{15 0 }{3} [/tex]
Therefore the measure of 2x is (2×50)°=100°.
Hopeit helps...
Answer:
X=50; 2x=2×50=100
Step-by-step explanation:
sum of angles in a quadrilateral is 360°
Therefore; x+2x+100+110=360;
3x+210=360;
3x=360-210;
3x=150;
divide both sides by the co-efficient of x;
3x/3=150/3;
x=50;
therefore 2x=2×50;
2x=100.
A portable music player has 2 gigabytes of storage and can hold about 500 songs. A similar but larger media player has 80 gigabytes of storage. About how many songs can the larger media player hold
Answers
Answer:
20,000.
Step-by-step explanation:
The first music player has 500 songs stored by 2 GB. So 500/2 is 250. You take 250 and you multiply it by 80 and you get 20,000.

Answer:

Step-by-step explanation:
Every weekday after tennis practice, Will buys either a carton of milk or a bottle
of power drink.
Suppose that m is the number of cartons of milk that Will purchased during
the last month. His total cost for beverages in dollars last month can be
represented by the algebraic expression 2m + 3 (20 – m).
Which of the following statements are true? Select all that apply.
The cost of the power drink is $3 per bottle,
Will purchased 20 more bottles of power drink than cartons of milk.
Will purchased a total of 20 beverages during the last month.
The total amount Will spent on power drinks was $60
An equivalent expression for the total cost of Will's beverages during this month is
60 - m dollars
Will purchased 20 more cartons of milk than bottles of power drink
Answers
Answer:
The correct options are;
The cost of milk powder is $3 per bottle
An equivalent expression for the total cost of Will's beverages during this month is 60 - m dollars
Step-by-step explanation:
The given information are;
The items Will buys every weekday after tennis practice = A carton of milk or a bottle of powder drink
The number of milk purchased during the month = m
Will's total cost for beverages in dollars last month = 2·m + 3·(20 - m)
1) Therefore, given that the total amount is factored in dollars, we have;
2·m and 3·(20 - m) are dollar amounts, while, m is a quantity;
Therefore;
Where;
2·m = The total cost of the cartons of milk, then the factor 2 represents $2.00 which is the cost per carton of milk
Similarly, 3·(20 - m) can be said to represent the total cost of the powder drink then the factor 3 represents $3.00 which is the cost per powder drink and the factor (20 - m), represents the number of powder drink Will buys for the month
From which we found the cost of milk powder = $3.00 per bottle
2) The expression, 2·m + 3·(20 - m) simplifies to 2·m + 60 - 3·m, which gives;
2·m + 60 - 3·m = 60 - m which is an equivalent expression for the total cost of Will's beverages for the month.
Find the set of values of k for which the y = kx – 4 intersects the curve of y = x2 – 2x at two distinct points.
Answers
Answer:
For ax^2+bx+c=0,
x^2+x(-2-k)+4=0,
So, b=-2-k,
a=1, c=4, so
(-2-k)^2-(4*1*4)>0,
4+4k+k^2-16>0,
k*2+4k-12>0,
(k+6)*(k-2)>0,
the points of interest are
k=-6, k=2, so
look at k<-6, -6<k<2, and
k>2.
Just plug in values for each
interval and you will see
that k<-6 and k>2.

4x = 88
x = 22
x + 2 = 24
x + 4 = 26
x + 6 = 28
