Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
Answer:
Angle E is 60 degrees
Step-by-step explanation:
So z is an angle.
That would be point E.
This triangle was dilatated so we can match it up with the larger one. In a dilation, angle measures do not change. So matching up the points E would be equal to A, which of course it the only one with an angle measure not given.
All you have to do is add up the two angle measures and subtract that by 180 (total of all angles combined).
So 65+55=120
180-120=60
Angle A is 60
Which makes angle E 60 as well
Hope that helps!

Which expression is equivalent to 5 ( x + 8)?
Answer:
your answer is (B) 5x-0.4
Step-by-step explanation:
The equivalent expression for the given function is -
y = 5x + 40.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is the expression -
5(x + 8)
We can write the equivalent expression for the given function is -
y = 5(x + 8)
y = 5x + 40
Therefore, the equivalent expression for the given function is -
y = 5x + 40.

Graph the relation. Is the relation a function? Why or why not?
{(-5, 6), (-2, 3), (3, 2), (6, 4)}
Yes; there is only one domain value for each range value.
Yes; there is only one range value for each domain value.
No; a domain value has two range values.
No; a range value has two domain values.
Answer:
Yes; there is only one range value for each domain value.
Step-by-step explanation:
For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.

The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?
Answer: 45
Step-by-step explanation:
3(-2m + 5) -6(-4m - 2) =
-6m + 15 + 24m + 12=
18m + 27
18= a 27= b 27 + 18= 45
The value of the expression a + b is 45.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we can simplify the expression using the distributive property:
3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12
Combining like terms, we get:
18m + 27
So, a = 18 and b = 27, which means:
a + b = 18 + 27 = 45
Therefore,
The value of a + b is 45.

Write the equation of
the circle with diameter
endpoints of (17,-3) and
(-13, 3).
The equation of the described circle is:
(x - 2)² + y² = 234
How to write the circle equation?Remember that the equation for a circle whose center is (a, b) and has a radius R, is:
(x - a)² + (y - b)² = R²
Here the endpoints of the diameter are (17,-3) and (-13, 3), then the center is at:
( [17 - 13]/2, (-3 + 3)/2)
(2, 0)
And the radius is the distance between the center and any of these points:
R = √( (2 - 17)² + (0 + 3)²)
R = √234
Then the equation is:
(x - 2)² + (y - 0)² = √234²
(x - 2)² + y² = 234

the half-life of chromium-51 is 38 days. If the sample contained 510 grams. How much would remain after 1 year?
Answer:
About 0.6548 grams will be remaining.
Step-by-step explanation:
We can write an exponential function to model the situation. The standard exponential function is:
[tex]f(t)=a(r)^t[/tex]
The original sample contained 510 grams. So, a = 510.
Each half-life, the amount decreases by half. So, r = 1/2.
For t, since one half-life occurs every 38 days, we can substitute t/38 for t, where t is the time in days.
Therefore, our function is:
[tex]\displaystyle f(t)=510\Big(\frac{1}{2}\Big)^{t/38}[/tex]
One year has 365 days.
Therefore, the amount remaining after one year will be:
[tex]\displaystyle f(365)=510\Big(\frac{1}{2}\Big)^{365/38}\approx0.6548[/tex]
About 0.6548 grams will be remaining.
Alternatively, we can use the standard exponential growth/decay function modeled by:
[tex]f(t)=Ce^{kt}[/tex]
The starting sample is 510. So, C = 510.
After one half-life (38 days), the remaining amount will be 255. Therefore:
[tex]255=510e^{38k}[/tex]
Solving for k:
[tex]\displaystyle \frac{1}{2}=e^{38k}\Rightarrow k=\frac{1}{38}\ln\Big(\frac{1}{2}\Big)[/tex]
Thus, our function is:
[tex]f(t)=510e^{t\ln(.5)/38}[/tex]
Then after one year or 365 days, the amount remaining will be about:
[tex]f(365)=510e^{365\ln(.5)/38}\approx 0.6548[/tex]

Answer:
31°
Step-by-step explanation:
The angle 59° will be equal to the angle c in triangle ABC.
Angle B will be 90°
Angle A + Angle B + Angle C = 180° (ASP)
Angle A + 90° + 59 ° = 180 °
Angle A = 180° - 90° - 59°
Angle A = 31°
Angle A = x
31° = x
