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)
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]

Answer:
A) m = 16/5
Step-by-step explanation:
We need to find the slope between a choice of two points in this function table. I'll choose points (5,16) and (10,32) however you can choose any point you want.
To find "m" which is the slope, we need to do the following:
m = (y2-y1)/(x2-x1)
m = (32-16)/(10-5)
m = 16/5
The answer is A) m = 16/5

Answer:
y=4/5x+2
Step-by-step explanation:
Answer:
y=0.8x+2
Step-by-step explanation:
First, you would figure out the slope using the following equation: (y2-y1)/(x2-x1)=slope.
So, (2--2)/(0--5)= 4/5, or 0.8. This would be the slope.
Then, you would figure out b by putting a data point from the given ones. I chose (0, 2).
2=0.8(0) + b --> 2=0 + b --> 2=b
So, the final equation is y=0.8x+2

A=pir^2 solve for pi
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]
Determine whether the given lines are parallel, perpendicular or neither.
2x + 3y = 1
3x – 2y = 1
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
These two equations are perpendicular it's pretty tough to figure it out with the only the equations like last time but if you graph it's more easier because it's visual.
So the equations solved for y is...
[tex]y=-\frac{2}{3} x+\frac{1}{3}[/tex]
[tex]y=\frac{3}{2}x-\frac{1}{2}[/tex]
What is the length of 15,409,000 cubic yard in miles? (to
the nearest hundred)
Answer:
Step-by-step explanation:
The cube root of 15,409,000 = 248.84 yards.
There are 1760 yards in a mile
One edge of a cube = 248.84 / 1760 = .141386 miles.
So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.
Given the figure below find the values of x and z.
Answer:
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.

Find the value of b for the triangle using the Pythagorean Theorem.
Step-by-step explanation:
Hey there!
Given;
The given figure is a Right angled triangle, taking reference angle as angle B.
Hypotenuse= AB=5
Base= CB= 4
Perpendicular= AC=b
Using Pythagorean theorem.
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]b = \sqrt{ {5}^{2} - {4}^{2} } [/tex]
[tex]b = \sqrt{25 - 16} [/tex]
[tex]b = \sqrt{9} [/tex]
Therefore, the value of b is 3.

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?
=============================================
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
The amount of available disk space on a digital video recorder changed from 81% to 9% after recording 12 episodes of a show. Each episode requires the same amount of disk space. Which statement is true? The change in available disk space is 6% per episode. The change in available disk space is −6% per episode. The change in available disk space is 7.5% per episode. The change in available disk space is −7.5% per episode.
Answer:
The change in available disk space is −6% per episode
Step-by-step explanation:
Given that :
Available disk space changed from 81% to 9% after recording 12 episodes of a show
Each episode requires the same amount of disk space
Change in disk space =
Final % = 9%
Initial percentage = 81%
Change = final value - initial value :
(9 - 81)% = -72%
72% reduction in disk space
Space taken up per episode :
Reduction in space / number of episodes
= -72% / 12
=- 6%

Help! marking branliest answer if gotten right!
Answer: x= 65
Step-by-step explanation:
Vertical angles are equal to each other. So, to solve, write the equation:
2x - 10 = 120
Add 10 to both sides
2x = 130
Divide both sides by 2
x = 65
Can someone please help me solve this question? 7-3r=r-4(2+r)
Answer:
There is no solution
Step-by-step explanation:
7−3r=r−4(2+r)
Step 1: Simplify both sides of the equation.
7−3r=r−4(2+r)
7+−3r=r+(−4)(2)+(−4)(r)(Distribute)
7+−3r=r+−8+−4r
−3r+7=(r+−4r)+(−8)(Combine Like Terms)
−3r+7=−3r+−8
−3r+7=−3r−8
Step 2: Add 3r to both sides.
−3r+7+3r=−3r−8+3r
7=−8
Step 3: Subtract 7 from both sides.
7−7=−8−7
0=−15
Answer:

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.
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°.

The graph below shows the amount of Michael’s paycheck based on a 40 hour work week, plus his commission from sales. Michael earns 50% of the total amount of sales that he makes.
Answer:
Option B.
Step-by-step explanation:
The graph attached shows the amount of Michael's paycheck based on 40 hour wok along with commission from the sales.
There are two variables plotted on the graph.
On x-axis → Amount of sales
On y-axis → Amount of paycheck he received
Point (0, 100) shows the y-intercept.
Since, y-coordinates show the amount of paycheck, y-intercept will show the amount ($100) at zero sales.
Therefore, Option B will be the correct option.
