Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday from his daily transportation allowance for 3 weeks. From these savings, he wants to buy a 3-layered lunch box which costs Php 195.75. How much more must he save?
A) Php 107.55
B) Php 8.20
C) Php 29.40
D) Php 170.55
Answers
Answer: Php 107.55
Step-by-step explanation:
From the question, Marlon saves Php 4.50 on Monday, Php 7.25 on Tuesday, Php 5.55 on Wednesday, Php 3.95 on Thursday, and Php 8.15 on Friday . The Total amount saved will be:
= 4.50 + 7.25 + 5.55 + 3.95 + 8.15
= 29.40
Amount saved for 3 weeks will be:
= 29.40 × 3
= 88.20
Since the lunch box he wants to buy costs Php 195.75 and he has saved Php 88.20. The remaining amount will be:
= 195.75 - 88.20
= 107.55

What is area covered by the beam to the nearest square foot?
31416 satt
184 sq.ft
7330 sq.ft
26389 sq.ft
Answers
Answer:
7330 sq.ft
Step-by-step explanation:
Area covered by the beam = Area of sector
Area of sector = [tex] \frac{\theta}{360} \times \pi r^2 [/tex]
Where,
[tex] \theta = 84° [/tex]
Radius (r) = 100 ft
Plug in the values into the formula
Area of sector = [tex] \frac{84}{360} \times \pi 100^2 [/tex]
Area of sector = [tex] \frac{84 \times \pi \times 10,000}{360} [/tex]
Area of sector = 7,330 ft² (nearest square foot)

At what value of x do the graphs of the equations below intersect?
2x − y = 6
5x + 10y = −10
Answers
Answer:
x = 2
Step-by-step explanation:
You would find a value of y to plug into either of the equations. For example, I chose the equation 2x - y = 6. When I set it equal to y, I got y = 2x - 6Now that I know what y is equal to, I plugged it into the second equation to get 5x + 10 (2x - 6) = -10You then would calculate for x.Your end result should be x = 2, which is the point that the two equations intersectThis works because the two equations are set equal to each other, making them share a common value between them.
You can also plug both of these equations into a graphing calculator, and on the graph select the command to calculate the intersection.
Hope this helped!
Answer:
x = 2
Step-by-step explanation:
Given the 2 equations
2x - y = 6 → (1)
5x + 10y = - 10 → (2)
Multiplying (1) by 10 and adding to (2) eliminates the y- term.
20x - 10y = 60 → (3)
Add (2) and (3) term by term to eliminate y, that is
25x = 50 ( divide both sides by 25 )
x = 2
The value of x at the point of intersection is x = 2
$22 skateboard; 25% discount
Answers
━━━━━━━☆☆━━━━━━━
▹ Answer
$16.50
▹ Step-by-Step Explanation
If you are trying to find the new price, we will deduct 25% from the original cost of $22.
To figure this out, you can multiply 0.25 * 22.
From there, you will get $5.50. This means there will be a $5.50 discount applied. To find the new cost, we will now subtract.
$22 - $5.50 = $16.50
The new cost of the skateboard is $16.50.

determine if l || m based on the information given on the diagram. If yes, state the converse that proves the lines are parallel.
Answers
Answer/Step-by-step explanation:
1. YES.
Converse: If same side interior angles are supplementary, then l || m. (Same side interior angles)
Since the sum of the two same side interior angles, 65° and 115°, equals 180°, therefore, l || m.
2. YES.
Converse: if two angles angles are a linear pair, they are supplementary, therefore l || m. (Linear pair)
Thus,
128° + 53° = 180°.
3. YES.
Converse: if two angles are corresponding angles and congruent, therefore l || m. (Corresponding angles).
Thus,
The indicated angles which are equal to 90°, are corresponding angles therefore, l || m.
4. YES
Converse: if two alternate exterior angles are congruent, then l || m. (Alternate exterior angles)
Thus, the two exterior angles are congruent, therefore l || m.
The converse which would serve as prove that l is parallel to m are given in the answers below:
Considering the information in the given diagrams:
1. Yes, l is parallel to m.
The converse is: "If corresponding angles are equal, then l is parallel to m". One of the corresponding angles plus [tex]115^{o}[/tex] equals [tex]180^{o}[/tex].
Thus, l || m.
2. Yes, l is parallel to m.
The converse is: "if two angles are linear pair, then they sum up to [tex]180^{o}[/tex]".
So then, l || m.
3. Yes, l is parallel to m.
The converse is: "if two corresponding angles are right angles, then they are congruent".
Therefore, l || m.
4. Yes, l is parallel to m.
The converse is: :if two alternate exterior angles are congruent, then l is parallel to m".
Therefore, l || m.

if angle a = (7x-27) and angle b = (3x + 29) , then find the value of x.
Answers
Answer:
x = 14
Step-by-step explanation:
7x - 27 = 3x + 29
Subtract 3x from both sides;
4x - 27 = 29
Add 27 to both sides;
4x = 56
Divide both sides by 4;
x = 14

y = 50
angle AOB = 100
=========================================
Explanation:
Angle x is an inscribed angle that subtends or cuts off minor arc AB. This is the shortest distance from A to B along the circle's edge.
Angle y is also an inscribed angle that cuts off the same minor arc AB. Therefore, it is the same measure as angle x. We can drag point D anywhere you want, and angle y will still be an inscribed angle and still be the same measure as x.
-------------------
Point O is the center of the circle. This is because "circle O" is named by its center point.
Angle AOB is considered a central angle as its vertex point is the center of the circle.
Because AOB cuts off minor arc AB, and it's a central angle, it must be twice that of the inscribed angle that cuts off the same arc.
This is the inscribed angle theorem.
Using this theorem, we can say the following
central angle = 2*(inscribed angle)
angle AOB = 2*(angle x)
angle AOB = 2*50
angle AOB = 100 degrees

A farmer is mapping out one of his fields and is placing markers to section off areas to use for different crops. He has placed marker 1 at the point (2, 1), marker 2 at the point (-3, 1), and marker 3 at the point (2, 5). If each unit on the grid is one kilometer, what's the distance between marker's 1 and 2?
Answers
Answer:
5km
Step-by-step explanation:
The distance between two coordinates is expressed as;
D = √(x2-x1)²+(y2-y1)²
Marker 1 is at coordinate (2,1) and marker 2 at (-3,1)
Substitute into the formula
D = √(-3-2)²+(1-1)²
D = √(-5)²
D = √25
D = 5
Hence the distance between marker one and two is 5km

In the figure below, triangle ABC is similar to triangle PQR, as shown below.
What is the length of side PQ? (1 point)
a-33
b-34
c-35
d-36
Answers
Answer: 36
Step-by-step explanation:
As you can see, side AB is similar with side PQ.
Also, side BC is similar with side QR.
If you divide the length of side QR (34.5) by the length of side BC (11.5)
you get 3.
3 is the ratio that you will use to find the other side. The ratio of triangle ABC to PQR is 1:3
Multiply the side of AB (12) by 3 and you will get 36.
The measure of side PQ in triangle PQR is 35 units. Therefore, option D is the correct answer.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Given that, triangle ABC is similar to triangle PQR.
By similar triangles statement, we have
AB/PQ = BC/QR
12/PQ = 11.5/34.5
12×34.5=PQ×11.5
11.5PQ=414
PQ=414/11.5
PQ=36
Therefore, option D is the correct answer.
