Alexi originally has $43 in his bank account and deposits $7 per week.
Week 1: $50
Week 2: $57
Week 3: $64
Week 4: $71
Week 5: $78
The pattern is that it increased $7 every week starting from $43.
A pattern rule would be: y = 7x + 43 where x represents the number of weeks.

Find the perimeter and the area of the composite shape..
Answer:
area- 36.07 cm^2
perimeter- 28cm
Step-by-step explanation:
1) we could break the composite shape into 2 seperate shapes:
1 shape- measuring 3.1 by 3.4 cm
2nd shape- measuring (3.1)+(3.8)cm by 3.7 cm
since both shapes are rectangles we can find area by multiplying length and width
so 3.1*3.4=10.54
and 3.1+3.8=6.9
6.9*3.7=25.53
we can add both areas up to get TOTAL area of figure:
25.53+10.54=36.07
area- 36.07 cm
to find perimeter: there are 2 unknown sides in this figure, the bottom side length can be found out by adding 3.1 and 3.8, which is 6.9 and the side adjacent to the bottom one can be found by adding 3.4 and 3.7, which is 7.1
now we add up all the numbers: 3.1+3.4+3.8+3.7+6.9+7.1= 28

the perimeter of a stop sign is 99.2 inches. Each side of the stop sign is equal.
Write and solve an equation to find the measurement of one side of the stop sign n.
Answer: The equation can be written as 8n = 99.2.
Step-by-step explanation:
In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.
A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.
Hence, the answer can be represented as 8n = 99.2.

The diagram shows the cross-section of a wall of a cinema. It has to be painted. Work out the area that needs to be painted.
Answer:
Area = 370 m²
Cost to paint = £105
Step-by-step explanation:
Area of the wall of a cinema hall = Area of a trapezoid (1)+ Area of a rectangle (2) + Area of a trapezoid (3)
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
where [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and h is the distance between these sides.
Area of trapezoid (1) = [tex]\frac{1}{2}(11+12)\times 6[/tex]
= 69 m²
Area of the rectangle (2) = Length × Width
= 12 × 15
= 180 m²
Area of the trapezoid (3) = [tex]\frac{1}{2}(12+10)\times 11[/tex]
= 121 m²
Now area of the wall = 69 + 180 + 121
= 370 m²
One tin covers the area = 25 m²
Number of tins required to paint the wall = [tex]\frac{\text{Total area}}{\text{Area covered by one tin}}[/tex]
= [tex]\frac{370}{25}[/tex]
= 14.8
Therefore, number of tins to be purchased = 15
Cost to paint the complete wall = 15 × £7
= £105

Ricardo buys at least 8.5 but no more than 11
gallons of gas each week. The price of gas has
ranged from $2.40 to $2.65 per gallon each
week.
Answer:
Here we have two inequalities.
P is price of the gallon,we have that:
$2.40 ≤ P ≤ $2.65
C is the amount of gallons that Ricardo buys each week.
8,5 ≤ C ≤ 11
Now, with this you can find the maximum and minimum amount that he can spend on a week.
The minimum is when he buys only 8.5 gallons and the price per gallon is $2.40
Cost = 8.5*$2.40 = $20.4
The maximum cost is when he buys 11 gallons, and the price of the gallon is $2.65
Cost = 11*$2.65 = $29.15
So the amount that he spends per week in gas, S, is:
$20.4 ≤ S ≤ $29.15
Circle O is shown. Line segments C O And A O are radii. Lines are drawn from points C and A to point B to form chords B C and B A. Angle C B A is 80 degrees. What is the measure of angle COA? 140° 150° 160° 170°
Answer:
Its 160 on ED
Step-by-step explanation:
Based on the angle-arc relationship, the measure of angle COA is: C. 160°.
What is the Angle-Arc Relationship?The angle-arc relationship relates the measure of an inscribed angle to its central angle, such that the central angle is twice the measure of the intercepted arc.
Given:
m∠CBA = 80° (intercepted arc)m∠COA = ?° (central angle)Therefore:
m∠COA = 2(m∠CBA)
Substitute
m∠COA = 2(80°)
m∠COA = 160°
Therefore, based on the angle-arc relationship, the measure of angle COA is: C. 160°.

1/4
Answer: 4
Step-by-step explanation: a is three units away from o and a’ is 9 units away from o. you add 9+3 to get the total distance and divide that number by 3 to get the scale factor. 12/3=4
The scale factor for the given dilation is 3
What is Dilation?Dilation is a transformation of an object which changes its size. if the dilated image is larger then it is called enlargement. If the dilated image is smaller it is called reduction.
If the dilation has the origin as the center of dilation, we can find points on the image formed by dilation by multiplying the coordinates of the original geometric object like triangle multiplying by the scale factor. For scale factor k, the transformation of the dilation is written as : (x, y) → (k x, k y).
The scale factor ,k = coordinate of image / coordinate of original
Given that Triangle ABC is dilated to create triangle A’B’C’ using point O as the center of dilation as shown in the figure
Scale Factor = coordinate of image / coordinate of original
= OA' / OA = 9/3 = 3
Therefore, the scale factor for the given dilation is 3.

Answer:
Usain Bolt runs about 37,383 meters an hour so he will not exceed the speed limit but will run at about 23 miles per hour.
Step-by-step explanation:
Usain Bolt runs about 37,383 meters an hour so he will not exceed the speed limit but will run at about 23 miles per hour. We get this from 3600 seconds in an hour, 3600÷9.63×100≈37383 meters an hour. 1609.344 meters in a mile. 37383÷1609.344≈23 mph

An American motor company is releasing a new car model. There will be 2 body styles (2 or 4 door) from which to choose. They also offer 3 interior packages (deluxe, luxury, or special edition) and an option of 2 drive trains (front-wheel or four-wheel drive). If a local dealer wanted one of each possible model on her sales lot, how many cars would she need to order?
Answer:
She needs to order 12 cars
Step-by-step explanation:
To find the total number of models, we just need to multiply the number of options for each choice:
body style: 2 options
interior package: 3 options
drive train: 2 options
So the number of different models is:
2 * 3 * 2 = 12 different models
So in order to have all the possible models, she needs to order 12 cars.

10. A school is trying to schedule periods of Chemistry and Algebra II.
They find that a total of 386 students are taking either one or both of
the two courses. If 298 students signed up for Algebra II and 328 have
signed up for Chemistry, what would be the probability that a student
chosen at random from the 386 will be signed up for both of the
courses? Round your answer to the nearest whole number percent.
Answer:
~62%
Step-by-step explanation:
Let n(A) be the number of students signed up for Algebra II.
Given that n(A) = 298
Let n(B) be the number of students signed up for Chemistry.
Given that n(B) = 328
n(A [tex]\cup[/tex] B) will be the number of students who have signed up for either one or both of two subjects.
n(A [tex]\cup[/tex] B) = 386
Formula for n(A [tex]\cup[/tex] B):
n(A [tex]\cup[/tex] B) = n(A) + n(B) - n(A [tex]\cap[/tex] B)
Where n(A [tex]\cap[/tex] B) is the number of students signed up for both the courses.
Putting the values in the formula above:
386 = 298 + 328 - n(A [tex]\cap[/tex] B)
n(A [tex]\cap[/tex] B) = 240
Formula for Probability of an event E:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
[tex]P(A \cap B) = \dfrac{n(A \cup B) }{n(A \cap B)}[/tex]
[tex]\Rightarrow P(A \cap B) = \dfrac{240 }{386}\\\Rightarrow P(A \cap B) = 62.17\%[/tex]
Hence, the required probability is ~62%
The probability that a student chosen at random from the 386 will be signed up for both of the courses should be 62%.
Calculation of the probability:
Since total of 386 students are taking either one or both of the two courses. If 298 students signed up for Algebra II and 328 have signed up for Chemistry
So here the no of students that signed up for both subjects should be
= 298 + 328 - 386
= 240
Now the probability is
[tex]= 240\div 386[/tex]
= 62%
Hence, The probability that a student chosen at random from the 386 will be signed up for both of the courses should be 62%.
