Angle B:22°
Angle C:158°
Step-by-step explanation:
1) c= 180°
22) b= 22 (vertical angle theorem)
a and c = 158 because you subtract b and 22° from 360 and you get 316 then divide by 2 to get a and c

Write the equation for a parabola with a focus at (−4,8)(-4,8)(−4,8)left parenthesis, minus, 4, comma, 8, right parenthesis and a directrix at x=−6x=-6x=−6x, equals, minus, 6.
Answers
Given:
The focus of the parabola is at (-4,8).
The directrix is at x=-6.
To find:
The equation of the parabola.
Solution:
The directrix is at x=-6, which is a vertical line. So, the parabola is horizontal.
The equation of a horizontal parabola is
[tex](y-k)^2=4p(x-h)[/tex]
Where, (h,k) is vertex, (h+p,k) is focus and x=h-p.
The focus of the parabola is at (-4,8).
[tex](h+p,k)=(-4,8)[/tex]
[tex]h+p=-4[/tex] ...(i)
[tex]k=8[/tex]
The directrix is at x=-6.
[tex]h-p=-6[/tex] ...(ii)
Adding (i) and (ii), we get
[tex]2h=-10[/tex]
[tex]h=-5[/tex]
Putting h=-5 in (i), we get
[tex]-5+p=-4[/tex]
[tex]p=-4+5[/tex]
[tex]p=1[/tex]
Putting h=-5, k=8 and p=1 in the standard form of the parabola.
[tex](y-8)^2=4(1)(x-(-5))[/tex]
[tex](y-8)^2=4(x+5)[/tex]
Therefore, the required equation of the parabola is [tex](y-8)^2=4(x+5)[/tex].
Answer:
x=[tex]\frac{(y-8)^{2}-20 }4}[/tex]

Answer: Factor of 0
For example, 5 × 0 = 0 so it is true that 0 ÷ 5 = 0. In this example, 5 and 0 are factors of 0. GCF(5,0) = 5 and more generally GCF(k,0) = k for any whole number k. However, GCF(0, 0) is undefined.

Answer:
Find the LCM
The LCM of
0,5 is 5.
Greatest common divisor is the largest number which divides two given numbers say 'a' & 'b'
Now let's say a=0 and b= 5
We know that: anything × 0 =0
Therefore 0÷5=0
In other words 5 is a divisor of 0
and 5 is the largest number which divides 5...
Therefore 5 is the greatest common divisor of of 0 and 5Or gcd(5,0)=5
Common divisors of 0 and 5 = 1,5 [0=1*0 ; 5=1*5] and [0=5*0 ; 5=5*1]

14 less than the quantity k times 6
(Write it as an algebraic expression)
Answers
Answer:
6k-14
Step-by-step explanation:
The algebraic expression for inequality is 14 < 6k.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the statement
14 less than the quantity k times 6
Now, k times 6 = 6k
and, 14 less than k times 6 can written into mathematical form as
14 < 6k
k > 14/6
k> 7/3.

A field is in the form of a rhombus having each side 81 m and altitude 25 m. What is the side of a square
field which has the same area as that of the rhombus?
Answers
Answer:
the side of a square is 45 m
Step-by-step explanation:
The computation of the side of the square field that contains the similar area as compared with rhombus is given below:
As we know that
Area of rhombus = Base × Altitude
= 81 × 25
= 2025
And, area of Square = Side × side
2025 = side^2
side = √2025
= 45m
Hence, the side of a square is 45 m

he perimeter of parallelogram ABCD is 80 cm. AD is 7 cm more than twice AB. Find the lengths of all four sides of ABCD.
Answers
Answer:
AB = 11
BC = 29
DC = 11
AD = 29
Step-by-step explanation:
First, draw out and label the parallelogram ABCD. I've done so for you below:
Now, to figure out what to label the sides, refer to:
AD is 7 more than twice AB.
"Than" means that whatever we write, we flip it. For example, 7 more then 5 would be 5+7. Though this may not be important for addition, it is for subtraction. For example, 7 less than 5. This would be 5-7, but if you wrote it wrong, it would be 7-5.
"Is" is key word for "=". So:
AD = 7 more than twice AB.
"Twice" means "two times." So:
AD = 7 more than 2(AB).
AD = 2(AB) + 7
Let's label AB as x.
If the perimeter is 80, then that means AD+AB+BC+DC=80.
We know that in a parallelogram, opposite sides are congruent. So:
AD+AD+AB+AB=80
(2x+7) + (2x+7) + x + x = 80
2(2x+7) +2x = 80
4x + 14 + 2x = 80
6x + 14 = 80
6x = 66
x = 11
AB = 11
AD = 2x + 7
= 2(11) + 7
= 22 + 7
= 29

135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

On the first night of Rosh Hashanah, David cuts 5 apple into slices and gives 3/8 of an apple to each of his quests. He has 2 apples left over. How many guests does David have?
Answers
Answer:
Number of guests = 8
Step-by-step explanation:
Total apples David cut = 5
Total apples left over = 2
Total apples David gave his guest = Total apples David cut - Total apples left over
= 5 - 2
= 3
Total apples David gave his guest = 3
Each guest gets = 3/8 of an apple
Number of guests = Total apples David gave his guest ÷ share of each guest
Number of guests = 3 ÷ 3/8
= 3 × 8/3
= 8
Number of guests = 8
