My little sister, Savannah, is three years old and has a piggy bank that she wants to fill. She
started with five pennies and each day when I come home from school, she is excited when I give her three pennies that are left over from my lunch money. How much money will Savannah have after 10 days? How many days will it take for her to have at least $1.50? Justify your answer with a mathematical model of the problem situation.

Answers

Answer 1

The amount of money Savannah will have after 10 days is $0.35

Convert penny to dollar

1 penny = $0.01

Amount Savannah started with = 5 pennies

= $0.01 × 5

= $0.05

Additional amount per day = 3 pennies

= $0.01 × 3

= $0.03

Number of days = 10

Total savings in 10 days = 0.05 + 0.03(10)

= 0.05 + 0.3

= $0.35

Number of days it will take for her to have at least $1.50 = 0.05 + 0.03d

1.50 - 0.05 = 0.03d

1.45 = 0.03d

d = 1.45 / 0.03

d = 48.33333333333333

Approximately,

d = 48.33 days

Therefore, the number of days it will take for her to have at least $1.50 us 48.33 days

Two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent.

Answers

Two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent: Always TRUE

What exactly does the term "triangle congruency" mean?Two triangles are said to be congruent if their three corresponding sides are equal and their three corresponding angles are equal in size.These triangles can be moved, rotated, flipped, and turned to appear identical.If they are repositioned, they will coincide.Two triangles are congruent if they satisfy all five congruence conditions.They are the side-side-side (SSS), side-angle-side (SAS), angle-side-angle (ASA), angle-angle-side (AAS), and right angle-hypotenuse-side  (RHS).

The statement states that:

Two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent.So, the statement is always true as it satisfies two conditions of congruency which are the SSS condition and AA condition.

Therefore, the statement "two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent" is Always TRUE.

Given two terms of each arithmetic sequence, find a₁ and d . a₃ =5 and a₅ =11

Answers

The two terms of each arithmetic sequence an=a1+(n-1)d are  2,7,12,17,..., 52.

What is sequence?

an=a1+(n-1)d

a1=2

a2=2+5=7

a3=7+5=12

a4=12+5=17

a11=2+(11-1)*5=2+10*5=2+50=52

so terms are 2,7,12,17,..., 52

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

We have to prove that all circles are similar.

We know that ;

A circle is a geometric shape in which the outside points are all equidistant from a center point.

Let's assume there are two circles and the radius of circle A is a and circle B is b .

If we center the circles on the same point, we found that by multiplying the radius of Circle B which is b by an unknown value x will give the radius of Circle A which is a.

At noon, Zoe is 249 miles away from the stadium and Mackenzie is 237 miles away from the stadium. Zoe is driving along the highway at a speed of 58 miles per hour and Mackenzie is driving at speed of 55 miles per hour. Let ZZ represent Zoe's distance, in miles, away from the stadium tt hours after noon. Let MM represent Mackenzie's distance, in miles, away from the stadium tt hours after noon. Write an equation for each situation, in terms of t,t, and determine whether Zoe or Mackenzie is closer to the stadium 2 hours after noon.

Answers

According to the question, the given data are as follows:

Zoe’s distance = ZZ(miles); Stadium time = tt (hours); Mackenzie’s distance = MM(miles)

Distance between Zoe and stadium = 249 miles

Distance between Mackenzie and stadium = 237 miles

Zoe speed = 58 miles per hour

Mackenzie speed = 55 miles per hour

Time = 2 hours

Using standard distance formula:

Distance = (speed)(time)

As per relative speed, distance gets added and speed gets subtracted when objects are away or parallel from each other.

ZZ = 249 -58tt

MM = 237 -55tt

When both are at the same distance, the time will be t = 4 hours

249 -58tt = 237 -55tt

tt = 4 hours

Answer:

Point (0, 0) satisfies the inequalities

Step-by-step explanation:

Sometimes graphing is the best way to determine where the region is that satisfies both inequalities. Then you can choose a point accordingly

The graph of both inequalities is attached. The heavily shaded region in blue represents the region that satisfies both inequalities

If you look at the graph, you can see that (0, 0) falls in the heavily shaded region and therefore it satisfies both constraints

Indeed at (0, 0)

7(0) + 2(0) = 0 which is > -4 since 0 is greater than all negative numbers

Also
-5(0) + 6(0) = 0 which is indeed ≤ 6

So one point is (0, 0)

An equation that could represent a linear combination of the system with  no solution is: B) 0 = 26.

What is no solution?

In Mathematics, no solution is sometimes referred to as zero solution. Additionally, an equation is considered as having no solution when the right hand side and left hand side of the equation are not the same or equal.

From the information provided above, we have this system of equations:

2x/3 + 5y/2 = 15     ........equation 1

4x + 15y = 12           ........equation 2

Multiplying equation 1 by 6, we have:

6 × (2x/3 + 5y/2 = 15)

4x + 15y = 90      ......equation 3

Subtracting the equation 3 from equation 2, we have:

A die is rolled. Find the probability of the outcome. P(1 or 6 )

Answers

The required probability is 1/3

Rolling a die is an equally likely event which means that probability of getting any number on rolling a die is same. When a die is rolled, there are total six outcomes in sample space which are 1, 2, 3, 4, 5, and 6 .

If a die is rolled once, then the probability of getting 1 is 1/6, and the probability of getting 6 is also 1/6.

These two events are mutually exclusive.

Thus, the probability of getting either 1 or 6 in a single throw is,

P(A or B) = P(A) + P(B)

P(A or B) = 1/6 + 1/6 = 2/6

P(A or B) = 1/3

Energy and mass are related by the formula, e=mc2, where m is the mass of the object and c is the speed of light. the equation that finds m, given e and c, is

Answers

Energy and mass are related by the formula, E = mc², where m is the mass of the object and c is the speed of light. The equation that finds m, given e and c, is:   m = E/c²

The equation, E = mc² was coined from Albert Einstein's theory of relativity, which shows the relationship between mass and energy. It shows that energy and mass can be interchanged into each other. The equation tells us that if we multiply the mass of a body (m) with the square of the speed of light (c²), we will get the total amount of energy (E) contained in that body, which can potentially be converted to other forms of energy.

However, if are given the energy contained in a body and the speed of light, then told to find the mass of the body, we will divide the equation by the coefficient of m. The coefficient of m in the equation is c², thus:

                          E = mc²

                          E/c² = mc²/c²

   c² divided by c² is 1, therefore, the new equation is:

                               m = E/c²

 Thus, the equation that finds m, given e and c is m = E/c².

Answers

The probability will:

a) Increase.

b) decrease.

c) increase.

How does the probability change?

We know that as larger is the size (or the diameter at least) of the hole, the easier will be to lading the skee ball on that hole.

So "If the size of the 40-point hole is enlarged, the probability... "

If you increase the size, then it will be easier to land the ball, thus we can conclude that the probability will increase.

" If the 40-point hole is made smaller, the probability..."

Opposite as the case above, this time will be harder to land the ball, thus the probability will decrease.

"If the 40-point hole stays the same size, but the scoring zone is made smaller, the probability..."

If the ball is thrown in a random way, such that the probability of landing in any region of the scoring zone is the same, then the probability of landing on the 40-point hole is equal to the quotient between the area of the hole and the total area of the scoring zone.

Thus, is you decrease the area of the scoring zone, then the probability increases.
