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]

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°.

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]

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]

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.

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.
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%

Maths > Mensuration
Mensuration
Suppose you want to put a boundary around your garden or field. For that, you need to find out the length of the boundary. Also, what if you want to find out the area and volume of different geometrical shapes. So this is something we are going to see in his chapter. So let us study the topic mensuration and mensuration formulas in detail.
Cylinder
Circles
Polygons
Rectangles and Squares
Trapezium, Parallelogram and Rhombus
Area and Perimeter
Cube and Cuboid
Question. Explain the use of mensuration in daily life?
Answer. The uses of mensuration in real life are many. Some of these uses are as follows:
Measurement of agricultural fields, and site areas for the purpose of purchase/selling transactions.
Measurement of volumes for packaging solid food items, milk, and liquids.
Measurements of surface areas for the purpose of estimating the painting of houses etc.
Question. What is meant by mensuration?
Answer. Mensuration refers to the branch of mathematics which involves the study of various geometrical shapes. Furthermore, it deals with the areas and Volume of such geometrical figures. So, this subject is all about the process of measurement.

Question. Explain what is the volume in mensuration?
Answer. Any solid occupies some region in space. Furthermore, the magnitude of this region is known as the volume of the solid. A standard unit of volume happens to be the cubic centimetre.
Question. What do we understand by mensuration formula?
Answer. A mensuration formula helps in computing the length-related properties of an object. This computation takes place on the basis of known lengths, areas, etc. Beyer (1987) came forward with a collection of mensuration formulas for the various plane and geometric figures. properties of an object.

Identify the written form of this number: 4,812,000. A. four hundred thousand, eight hundred twelve B. four thousand and eight hundred twelfths C. four million, eight hundred twelve thousand D. four billion, eight hundred twelve million Help please
Answer: C. four million, eight hundred and twelve thousand
Step-by-step explanation:
4,812,000.
When a figure consists of 7 numbers, it is regarded as millions. For example, 8,000,000 is right million on words.
4,812,000 will therefore be called four million, eight hundred and twelve thousand.
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.
A line passes through the point (-5,-2) and (0,2) write the equation in point-slope form
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
