Refer to the figure at the right. If
m22 = (a + 15)° and m23 = (a + 35)°, find the
value of a such that HĽ I HJ.
Answers
Answer:m∠1 = 145°
m∠2 = 35°
m∠3 = 35°
m∠4 = 145°
m∠5 = 145°
m∠6 = 35°
m∠7 = 35°
m∠8 = 145°
Step-by-step explanation:
The required value of a is 20°.
What are complementary angles?In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles.
Now it is given that,
m22 = (a + 15)° and m23 = (a + 35)°
Let m22 and m33 be the angle between HL and HJ.
And since HL is perpendicular to HJ therefore they are complement ot each other.
Thus,
m22 + m23 = 90°
⇒ (a + 15)° + (a + 35)° = 90°
⇒ a° + 15° + a° + 35° = 90°
⇒ 2a° +50° = 90°
⇒ 2a° = 90° - 50°
⇒ 2a° = 40°
⇒ a° = 40°/2
⇒ a° = 20°
Thus, the required value of a is 20°.

On Monday, Jayla raised $ 30 and Carlos raised $ 50. After that, Jayla raised $ 12 per day and Carlos raised $ 7 per day. After how many days will they have raised the same amount? They will raise the same amount after days. (Only type in the number for your final answer)
Answers
Answer:
4 days
Step-by-step explanation:
For Jayla:
[tex]Base\ Amount = \$30[/tex]
[tex]Additional = \$12[/tex] daily
For Carlos:
[tex]Base\ Amount = \$50[/tex]
[tex]Additional = \$7[/tex] daily
Represent the number of days with d
Jayla's expression can be represented using:
[tex]30 + 12*d[/tex]
Carlos' can be represented as:
[tex]50 + 7 * d[/tex]
Equate both expressions:
[tex]50 + 7 * d = 30 + 12 * d[/tex]
[tex]50 + 7d = 30 + 12d[/tex]
Collect Like Terms
[tex]12d - 7d = 50 - 30[/tex]
[tex]5d = 20[/tex]
Solve for d
[tex]d = 20/5[/tex]
[tex]d = 4[/tex]

The equation for lines can be written as y = –6x + 2. Line t includes the point (–6, –7) and is perpendicular to line s. What is the equation of line t?
Answers
y=1/6x-6
Explanation:
What we know:
- Equation for line S: y=-6x+2
- Line T is perpendicular to line S
- Line T passes through the point (-6,-7)
To find the answer, we would need to understand two things, the first being what exactly is going on with the equation: y=-6x+2.
It’s organized in slope-intercept form, which is y=mx+b. Here’s what the variables mean:
Y=the y variable
M=the slope
X=the x variable
B=the y-intercept (the point on the line that crosses the y axis)
Knowing this, we can look at the equation for line S again: y=-6x+2. -6 is the slope of line S and 2 is the y-intercept of line S.
The second thing we need to understand is that the slope of a second line that is perpendicular to the first line is equal to the NEGATIVE RECIPROCAL of the slope of the first line.
Reciprocal: the “flip” of a fraction where the denominator and the numerator switch places
So, for example, let’s say the slope of line A=6. The slope of the line perpendicular to line A would be -1/6.
Let’s try another example: the slope of line B=-4/5. The slope of the line perpendicular to line B would be 5/4 (because two negatives makes a positive)
And here, for your question, the slope of line S=-6. Therefore, the slope of line T would be 1/6.
Awesome! We found the slope, which means so far, the equation of line T looks like this:
y=1/6x+b
All we need now is the y-intercept, which is “b” in the equation y=mx+b.
To do this, we plug in the point that the question provided us, (-6,-7), and solve. We would plug in -7 as the y variable and -6 as the x variable.
y=1/6x+b
-7=1/6(-6)+b
1) multiply 1/6 and -6
-7=-1+b
2) add 1 to both sides of the equation to isolate b
-6=b
Aha! There we have it, -6 is the y-intercept of line T.
Now, we have completed our equation:
y=1/6x-6
I hope this helps! Please comment if you have any questions.

(5, -8) m = -3
Write an equation in point-slope form
Answers
Answer:
y + 8 = - 3(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (5 - 8) , thus
y - (- 8) = - 3(x - 5) , that is
y + 8 = - 3(x - 5)
the function f(x)=5(2)x represents number of bacteria, f(x), growing in a culture after x hours. How many bacteria are in the culture after 3 hours?
Answers
=============================================
Explanation:
Assuming the function is f(x) = 5(2)^x, then we replace every x with 3. Then we use the order of operations PEMDAS to simplify. Or we can use a calculator to simplify in one step.
f(x) = 5(2)^x
f(3) = 5(2)^3
f(3) = 5(8)
f(3) = 40

Is anyone able to help me with finding the volume of the triangular prism
Answers
Answer:

Step-by-step explanation:
Volume = area * height.
Take any of the given faces. I have taken 12m & 12 m.
Area of this face = 1/2 * 12m * 12m
= 72 m²
Height = 18 m.
Thus,
Volume = 72m² * 18m = 1296 m³

A=pir^2 solve for pi
Answers
Given problem;
A = [tex]\pi[/tex] r²
Solve for π;
To solve for π implies that we make it the subject of the expression.
So;
A = π r²
Now multiply both sides by [tex]\frac{1}{r^{2} }[/tex]
So;
A x [tex]\frac{1}{r^{2} }[/tex] = [tex]\pi[/tex] x r² x [tex]\frac{1}{r^{2} }[/tex]
r² cancels out from the right side and leaves only π;
π = [tex]\frac{A}{r^{2} }[/tex]
So [tex]\pi = \frac{A}{r^{2} }[/tex]

Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So first I would do...[tex]9x+39+12x-48=180[/tex] first because it'll give me the x value, so....
[tex]9x+39+12x-48=180\\21x-9=180\\21x=189\\x=9[/tex]
So now we know that the x equals 9 so we plug it in for (9x+39) because it's vertical to the other angle across from it and vertical angles are always congruent, so...
[tex]z=9(9)+39\\z=81+39\\z=120[/tex]
so now we know that x=9 and z=120.
