Each month Marla pays a $30 cell phone bill from her bank account. At the
end of one year, what is the change in the amount of money in Marla's account
because of her cell phone bill? Write a multiplication equation to represent the
problem. Explain what the product represents.

Answers

Answer 1

Answer:

-$360.00 change

Step-by-step explanation:

Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change.  But the way the question is worded it is stating she is paying $30 over 12 months.  This means she has paid $360.00 in that 12 months aka 1 year.  Her bank account should have had a balance.  So you could technically say B for balance.  B-30*12.  To get your answer.  Although there are many ways to write an equation expression of this question.  If you know the starting balance then it's better.  But you could assume her starting balance was $0.  Which would be 0-30M*12 where M could represent monthly.  And the same answer would occur of 360.  Is there more information?

30*12= X (x equals the total paid)

X-30*12 (if x is her balance before paying any money)

If the length of a side of a square is increased from 4 to 8, which of the following statements is true?

A.) Both area and perimeter are doubled.
B.) Both the area and perimeter are quadrupled.
C.) The perimeter is doubled and the area is quadrupled.
D.) The perimeter is quadrupled and the area is doubled.

Answers

Answer:

C.) The perimeter is doubled and the area is quadrupled.

Step-by-step explanation:

Original square: side = 4

Area = side^2 = 4^2 = 16 square units

Perimeter = 4 * side = 4 * 4 = 16 units

Larger square: side = 8

Area = side^2 = 8^2 = 64 square units

Perimeter = 4 * side = 4 * 8 = 32 units

Comparison of areas:

(larger square area)/(original square area) = 64/16 = 4

Comparison of perimeters:

(larger square perimeter)/(original square perimeter) = 32/16 = 2

Answer:

C.) The perimeter is doubled and the area is quadrupled.

A group of 8 friends went to lunch and spent a total of $76, which included the food bill and a tip of $16. They decided to split the bill and tip evenly among themselves.

Which equations and solutions describe the situation? Select two options.
The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.
The equation StartFraction 1 over 8 EndFraction (x + 16) = 76 represents the situation, where x is the food bill.
The solution x = 60 represents the total food bill.
The solution x = 60 represents each friend’s share of the food bill and tip.
The equation 8 (x + 16) = 76 represents the situation, where x is the food bill.

Answers

Answer:

1) The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.

2) The solution x=60 represents the total food bill.

These both answers are correct.

Step-by-step explanation:

Since there are 8 group of friends, and the total amount spent by them is $76 including the tip i.e $16.

If x is the food bill our equation can be:

(x+16)/8 = 76/8

 

(x+16)/8 = 9.5

x+16= 9.5*8

x= 76 -16

x= 60

The food bill is x=60.

Part I. A New Bike and Skateboard Problem

Uncle Eddie asked McKenna and Lara to order 108 new wheels for the 42

skateboards and bicycles in his repair shop. How many bicycles and how

many skateboards are in Uncle Eddie's shop?

Answers

Answer:

Number of bicycles = 30

Number of skateboards = 12

Step-by-step explanation:

Let the number of bicycles = x

Let number of skateboards = y

It is given that there are total bicycles and skateboards = 42

∴ x + y = 42  ........(1)

Now a bicycle has two tires and a skateboard has four tires, this gives an equation :

2x + 4y = 108 .......(2)   (Since uncle Eddie asks to order 108 tires)

Therefore, solving equation (1) and (2), we get

2(x+y=42)

2x+4y=108

  2x+2y = 84

- (2x+4y = 108)  

      - 4 y = - 24

    or   4 y = 24

   or      y = 12

Now substituting the value of y in equation (1),

x + 12 = 42

x = 42 -12

x = 30

So number of bicycles = x =30

And number of skateboards = y = 12

Angle of depression

According to the question,

In ΔABC,

∠XCA = ∠CAB = 72°

∠YCB = ∠CBA = 40°

Now,

→ ∠A + ∠B + ∠C = 180°

By putting the values,

  72° + 40° + ∠C = 180°

           112° + ∠C = 180°        

                     ∠C = 180° - 112°

                           = 68°

By applying Sin Rule,

→ [tex]\frac{AB}{Sin \ 68^{\circ}} = \frac{AC}{Sin \ 40^{\circ}}[/tex]

        AC = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex]

We know that,

Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° ...(Equation 1)

Area of ΔABC = [tex]\frac{1}{2}[/tex] × AB × h ...(Equation 2)    

From "Equation 1 and 2",

→ [tex]\frac{1}{2}[/tex] × AB × AC × Sin 72° = [tex]\frac{1}{2}[/tex] × AB × h      

                                   h = AC × Sin 72°

By substituting value of "AC",

                                      = [tex]\frac{360\times Sin \ 40^{\circ}}{Sin \ 68^{\circ}}[/tex] × Sin 72°

                                      = 237.36 or, 273 m

Answer:

45 degrees

Step-by-step explanation:

Using the pythagorean theorem, the 3rd side=19. So the triangle is isosceles and therefore the 2 angles we don't know the measure of are congruent. One angle measures 90 degrees. So the last 2 angles must be 90 together, since we know a triangle equals 180 degrees. Therefore the angle we are trying to find is 45 degrees.

In PQR, Q= 76, PQ = 18, and QR = 27
Please find angle P, T and PR for 5

Answers

Answer:

Step-by-step explanation:

Given:

m<Q = 76°

PQ = r = 18

QR = p = 27

Required:

Find P, T, and PR (q)

Solution:

✔️To find PR(q), apply the Law of Cosines.

Thus:

q² = r² + p² - 2rp×cos(Q)

Plug in the values

q² = 18² + 27² - 2×18×27×cos(76)

q² = 1,053 - 235.148

q² = 817.852

q = √817.852

q = 28.6 (nearest tenth)

✔️Find P by applying the Law of Sines:

[tex] \frac{sin(P)}{p} = \frac{sin(Q)}{q} [/tex]

Plug in the values

[tex] \frac{sin(P)}{27} = \frac{sin(76)}{28.6} [/tex]

[tex] sin(P) = \frac{sin(76)*27}{28.6} [/tex]

[tex] sin(P) = 0.9160 [/tex]

[tex] P = sin^{-1}(0.9160) [/tex]

P = 66.3° (nearest tenth)

✔️R = 180 - (P + Q)

R = 180 - (66.3 + 76)

R = 37.7°

what conclusions can you give why some students decided not to go to school?​

Answers

Step-by-step explanation:

There are a number of reasons why some students decide not to go to school. Some of them may be associated with family and psychological problems such as anxiety and depression, which should be investigated by trained professionals at the school if there is any suspicion of these symptoms.

There is also the possibility that students who have decided not to go to school have been victims of bullying and aggression at school, which causes fear of retaliation and psychological trauma that negatively impact the person's life.

It is important that schools provide psychological support and an active policy that combats bullying and is pro-integration of students and diversity.

Only 3% of turtle hatchlings will live to become breeding adults. How many turtles must have been born if the current number of breeding adults is 1,200?

Answers

Answer:

116400 I believe not 100% sure tho

The total number of turtles born is 40,000.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, only 3% of turtle hatchlings will live to become breeding adults.

The current number of breeding adults is 1,200

Let the total number of turtles born be t.

Now, 3% of t=1200

3/100 ×t=1200

3t=120000

t=40000

Therefore, the total number of turtles born is 40,000.

On a certain hot summers day, 672 people used the public swimming pool. The daily prices are $1.50 for children and 2.50 for adults. The receipts for admission totaled $1289.00. How many children and how many adults swam at the public pool that day?

Answers

Adults = 281
Children = 391

We have two equations: number of people and money. I’ll use a for adults, c for children.

a + c = 672
2.5a + 1.5c = 1289

First we’ll solve for number of adults in terms of c
a = 672-c

Then drop that expression into the second equation to solve for a numerical value for c

2.5(672-c) + 1.5c = 1289
1680 - 2.5c + 1.5c = 1289
-c = -391
c = 391

Now put that into the first equation to get a numerical value for a

a + 391 = 672
a = 281

Checking the math:
2.5(281) + 1.5(391)
= 702.5 + 586.5
= $1289
