Mrs. Bogaczyk got bored and decided to go on an Amazon spending spree! She bought 3 pairs of flip flops for $14.95 each, a sundress for $21.50 and two tanks tops...One that was $9.99 and one that was $15.44. The tax came to $7.34 but shipping was free. How much did Mrs. B. Spend altogether? If the budget for spending was $100, how much money does Mrs. B. Have left?
Step-by-step explanation:
3 pairs of flip flops = 14.95 x 3 = 44.85
Total amount spent = 44.85 + 21.50 + 9.99 + 15. 44 = 91.78
After adding tax = 91.78 + 7.34 = 99.12
Mrs B spent 99.12 altogether
Budget = 100
Then money left = 100 - 99.12 = 0.88

Answer:
- The number of small boxes that will fill the large box 1 = 64
- The number of small boxes that will fill the large box 2 = 56
Step-by-step explanation:
Complete Question
Items for a fundraiser are packaged in small boxes shaped like rectangular prisms that are 4.5 inches long, 4.5 inches wide, and 8 inches tall. To transport the items to an event, you want to know how many of the small boxes will fit in larger boxes. The larger boxes are available in two sizes. Large Box 1 is 24.25 inches long, 18 inches wide, and 24 inches tall. Large Box 2 is 20.5 inches long, 18.5 inches wide, and 24 inches tall. Both the small and large boxes must remain upright.
Solution
To know how many of the small boxes will fit in larger boxes, we need to obtain the volumes of the small box, large box 1 and large box 2.
Volume of a cuboid = L × W × H
For the small box,
Length = L = 4.5 inches
Width = W = 4.5 inches
Height = H = 8 inches
Volume of the small box = 4.5 × 4.5 × 8 = 162 in³
For large box 1,
Length = L = 24.25 inches
Width = W = 18 inches
Height = H = 24 inches
Volume of the large box 1 = 24.25 × 18 × 24 = 10,476 in³
For large box 2
Length = L = 20.5 inches
Width = W = 18.5 inches
Height = H = 24 inches
Volume of the large box 2 = 20.5 × 18.5 × 24 = 9,102 in³
The number of small boxes that'll fill the large box 1 = (10,476/162) = 64.667 = 64 small boxes (rounded down because the fraction cannot be forced into the large box 1.
The number of small boxes that will fill the large box 2 = (9,102/162) = 56.185 = 56 small boxes.

What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
2(x + 1)² + 6 = 134
Simplify the equation, then we have

2(x + 1)² = 128
(x + 1)² = 128 / 2
(x + 1)² = 64
Take square root on both sides. Then we have
(x + 1) = ± 8
x = - 1 ± 8
x = - 1 - 8, - 1 + 8
x = - 9, 7
The missing step that Sarah has to write as the result of Step 1 will be 2(x + 1)² = 128.

Tina and Tammy both get paid an equal hourly wage of $12 per hour. This week, Tina made an additional $46 in overtime. Select the expressions below that represent the weekly wages of both if x the number of hours
Tina worked this week and y= the number of hours Tammy worked this week
Answer:
Expressions B, D and E
Step-by-step explanation:
Here, we are to select which of the options is correct.
Let’s put in mind that they bought earn $12 per hour
x represents the number of hours Tina worked this week; the total amount of money she made would thus be x * 12 = $12x
Remembering that she made $46 overtime, the total amount of money she made that we would be $12x + 46
The total amount Tammy made, earning $12 per hour and working for y hours = $12 * y = $12y
The total amount of money both made is thus;
12x + 46 + 12y
= $(12x + 12y + 46)
Now, we have similar expressions in the question;
These are; expression B, expression D and expression E
While expression B is straightforward, the others are not
expression D is gotten by factoring out 12; 12x + 12y + 46 = 12(x + y) + 46
expression E just involved putting what each of the two earned in brackets
There are 30 fruits, all apples and peaches, in a basket. Take out any three of them and at least one will be an apple. How many peaches might there be in the basket?
Answer:
There are a maximum of 2 peaches in the basket.
Step-by-step explanation:
There are 30 fruits in a basket, all apples and peaches.
If 3 fruits are taken out of the basket, it is said that at least one of the 3 fruits would be an apple.
For this to be possible, it means, picking 3 fruits, at random from the basket guarantees at least 1 of them being an apple.
This means that the maximum number of peaches obtainable from the basket is 2, to guarantee a sure case of the last fruit of 3 selected fruits being an Apple. There has to be a minimum of 28 apples in the basket for this statement to be absolutely non-contestable.

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.
To the nearest cent, how much interest will he earn in 5 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer:
A = $ 7,299.92
A = P + I where
P (principal) = $ 6,000.00
I (interest) = $ 1,299.92
Step-by-step explanation:
A = P(1 + r/n)nt
Where:
A = Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
R = Annual Nominal Interest Rate in percent
r = Annual Nominal Interest Rate as a decimal
r = R/100
t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
n = number of compounding periods per unit t; at the END of each period
Simplify Negative 3 over 2 divided by 9 over 6.
Answer:
-1
Step-by-step explanation:
So in this case your dividing -3/2 by 9/6
So a strategy I learned was KCF aka. keep change and flip.
Therefore, in this case you keep -3/2
You change the dividing sign into multiply and then you flip 9/6 which makes 6/9.
These leaves us with -3/2 x 6/9
After multiplying, you'll probably get -18/18.
Which leaves us with -1 since if you divide a positive by a negative or a negative by a positive it'll give you a negative number.
Hopefully this helped! :)

Donnie deli man delivered 595 box lunches for the robotics convention. There were 20 more turkey sandwiches then roast beef. There were twice as many roast beef has PB&J. How many of each type of BoxLunch did Donnie delivered?
Answer:
250 turkey sandwiches were delivered.
There were 230 roast beef delivered.
115 PB&J were delivered.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
x is the number of turkey sandwiches.
y is the number of roast beef.
z is the number of PB&J.
Donnie delivered 595 box lunches
This means that [tex]x + y + z = 595[/tex]
There were 20 more turkey sandwiches then roast beef.
This means that [tex]x = y + 20[/tex]
There were twice as many roast beef has PB&J.
This means that [tex]y = 2z[/tex].
So in the second equation, we have that [tex]x = 2z + 20[/tex]
Replacing this in the first equation:
[tex]x + y + z = 595[/tex]
[tex]2z + 20 + 2z + z = 595[/tex]
[tex]5z = 575[/tex]
[tex]z = \frac{575}{5}[/tex]
[tex]z = 115[/tex]
115 PB&J were delivered.
[tex]x = 2z + 20 = 2*115 + 20 = 250[/tex]
250 turkey sandwiches were delivered.
[tex]x = y + 20[/tex]
So
[tex]y = x - 20 = 250 - 20 = 230[/tex]
There were 230 roast beef delivered.

Here is a diagram of a person standing next to a lorry.
The diagram shows two centimetre rulers.
The person and the lorry are drawn to the same scale.
The lorry is approximately 9.5 m in length.
Using the scale diagram, estimate the height of the person in metres.
Answer:
The person is a about 2m
The height of the person is 0.475m.
What is the scale factor?The scale factor is the ratio of the size image in scale and original size of the image.
Scale factor= new size/ original size
Here given that the length of the lorry is 9.5 m= 9.5*100 cm= 950 cm
But in scale, the length of the lorry is 10cm
scale factor =new size/ original size= 10/950= 1/95
Similarly for the person height of the person on the scale is given = 2cm
As from above it is clear that
scale factor= 1/95
new size/ original size= 1/95
2/ original size= 1/95
original size= 95/2
original size= 47.5 cm
original size= 47.5/100 m= 0.475 m
Therefore the height of the person is 0.475m.

Find the GCF of the numbers 16 and 72
Answer:
8
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
The Greatest Common Factor of two numbers is the largest whole number that goes into both of them. To find it, we can lay out all the factors of each number and pick the largest one.
Factors of 16: 1, 2, 4, 8, 16
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
The largest number that shows up on both lists of factors is 8, so the GCF of 16 and 72 is 8.
A car traveled 360 miles in 4 hours. If its speed were to be 15 mph slower, how long would it take to travel the same distance?
Answer: 4.8 hours.
Step-by-step explanation:
To find how long it would take to travel the same distance at a slower speed, find the speed the car is currently driving at.
Speed is distance over time, or in this case, miles per hour.
360 / 4 = 90 miles per hour.
The car is travelling 15 miles per hour slower, so the new speed is 90 - 15, or 75 miles per hour.
You can now use the same equation to find the time travelled:
360 / x = 75
360 = 75x
Divide both sides by 75 to get your answer:
4.8 = x
It would take the car 4.8 hours to travel the same distance.
