SUPER EASY AND REALLY URGENT!!
Answer:
is your answer $3250
Step-by-step explanation:
so we dont know our I (interest) but :
P (principal) = 10000
R (rate) = 6.5% we'll have to turn it into the decimal which is 0.065
T (time) = 5 years
and our basic formula of finding I is I = PxRxT so :
I = 10000 x 0.065 x 5
I = 3250
There are 225 dozen cookies in the bakery. How many cookies are there?
Answer:
2700 cookies.
Step-by-step explanation:
A dozen is a grouping of twelve, that is a dozen = 12.
If there are 225 dozen cookies in the bakery, then there are
[tex]225\cdot 12=2700[/tex] cookies in the bakery.
there are 2700 cookies in total
Since there are 225 dozen cookies in the bakery, we need to determine the total number of cookies.
To convert dozen to individual units, we multiply the number of dozens ( 225 ) by 12, as there are 12 cookies in each dozen :
225 dozen * 12 cookies / dozen = 2700 cookies
Therefore, there are 2700 cookies in total. By multiplying the number of dozens by 12, we account for the fact that each dozen contains 12 cookies. This calculation allows us to determine the precise quantity of cookies in the bakery.

Jay is 4 years younger than three times Tamia's age. Jay is 20 years old. How old is Tamia?
Final answer:
To find Tamia's age, an equation was set up based on the relationship between Jay and Tamia's ages. Jay is 20 years old and 4 years younger than three times Tamia's age. Solving the equation shows that Tamia is 8 years old.
Explanation:
Jay is 4 years younger than three times Tamia's age. Given that Jay is 20 years old, we can use this information to find out how old Tamia is. Let's denote Tamia's age as T. The relationship between their ages can be represented by the equation: Jay's age = 3 × Tamia's age - 4. Since Jay's age is 20, we can substitute this into the equation, giving us 20 = 3T - 4.
To solve for T, we first add 4 to both sides of the equation, which gives us 24 = 3T. Next, we divide both sides by 3 to find Tamia's age, resulting in T = 8. Therefore, Tamia is 8 years old.
This problem was solved by setting up an equation based on the relationship described between Jay and Tamia's ages, then using basic algebraic steps to solve for Tamia's age.

b- 0.5
c- 0.8
d- 1.4
Answer:
We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallon
Answer:
B
Step-by-step explanation:
70 miles * [1.6 km/mile] = 112 km
Notice when you multiply by km/mile by miles the miles cancel out.
1 gallon will get 112 km
x gallon will get 60 km
1/x = 112/60 cross multiply1 * 60 = 112 * x divide by 11260/112 = x switchx = 60/112 Do the divisionx = 0.54 Which rounds to 0.5Multiply. Express your answer in simplest form. 7/10 × 2/5

Bradley wanted a blue gumball and a green gumball from a vending machine. There were 15 blue gumballs, 12 yellow gumballs, 2 green gumballs, and 16 purple gumballs. How many times would you expect to get a blue gumball or green gumball if a gumball was taken out 250 times?
Answer: Bradley would expect 94 times to get a blue or green gumball.
Step-by-step explanation:
Since we have given that
Number of blue gumballs = 15
Number of yellow gumballs = 12
Number of green gumballs = 2
Number of purple gumballs = 16
Total number of all gumballs = 45
Probability of getting either a blue gumball or green gumball be
[tex]\frac{15}{45}+\frac{2}{45}=\frac{17}{45}[/tex]
So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :
[tex]\frac{17}{45}\times 250=94.4[/tex]
Since we know that it must be less than 94.4.
So, the nearest smallest integer will be 94 times .
Hence, Bradley would expect 94 times to get a blue or green gumball.

On the model scale drawing, approximately how far should each edge of the bed be from its own corner of the wall? Use complete sentences to explain your reasoning.
Solution:
Considering room to be in the shape of Cuboid as well as the Bed to be in the shape of Cuboid.
Dimensions of Room
Let Length of cuboid which is in the shape of room = L
Breadth of cuboid which is in the shape of room = B
Height of cuboid which is in the shape of room = H
Considering, L>B>H
Dimension of Bed
Length=[tex]\frac{L}{6}[/tex] units
Breadth=[tex]\frac{B}{4}[/tex] units
Height=[tex]\frac{H}{6}[/tex] units
Taking one corner at origin i.e (0,0,0)
You can keep your bed at any place inside the room, but you want your bed to be at that place inside the room where the window is located so that proper ventilation and sunlight can enter your room.
Taking bed to be in the middle of room near the window and considering it's upper face
Distance from one corner i.e from length= B- [tex]\frac{B}{4}[/tex]=[tex]\frac{3B}{4}[/tex] Units
Distance from other corner= 0 Units
Distance from Breadth of one side of wall= [tex]\frac{L}{3}[/tex] units
Distance from one corner i.e from Breadth =L - [tex]\frac{L}{3}[/tex]-[tex]\frac{L}{6}[/tex]= [tex]\frac{L}{2}[/tex]
Distance from floor i.e surface=[tex]\frac{H}{6}[/tex] units
Distance from Ceiling= H -[tex]\frac{H}{6}[/tex] = [tex]\frac{5 H}{6}[/tex] units
To find the distance each bed edge should be from the corner in a scale drawing, determine the scale used (such as 1 inch = 6 feet), convert actual bed dimensions using the scale, and ensure measurements on the drawing are precise and noted with the correct line types.
To determine how far each edge of the bed should be from its own corner of the wall in a scale drawing, first establish the scale being used for the model. For example, if the scale is 1 inch = 6 feet, convert the actual dimensions of the bed into the scale size by using ratios that compare the scale distance to the actual distance. If the actual bed is 6 feet long, then the length on the scale model would be 1 inch. When recording measurements, both the actual size and the scale size should be clearly marked to prevent confusion. It is important to use correct line types and to make all the drawings to exact measurements within the constraints of the paper size.
For consistent and accurate representation, the edges of the bed should be measured from the corner of the walls based on the determined scale. This involves calculating the distance of the bed from the wall in actual size, then converting that distance to the scale model size. Pay attention to significant figures and the choice of units (inches, feet, centimeters, meters) to maintain precision in your scale drawing.

Answer: C) 8Brian rented a book from the book shop.The shop charges $2 for the first day and $3 from the second day onwards.Brian took more then 2 days to return the book and he paid $35 while returning the book.How many days did he keep the book with him?
Brian rented the book for 12 days.
Brian rented a book with the condition that the shop charges $2 for the first day and $3 from the second day onwards. He paid a total of $35 upon returning the book. To determine how many days he kept the book, we must calculate the cost for each day and subtract the initial $2 from the total amount paid.
Steps to Calculate the Number of Days:
Subtract the first day's charge from the total amount: $35 - $2 = $33.Divide the remaining amount by the daily charge starting from the second day: $33 / $3 = 11 days.Add the first day to the result: 11 days + 1 day = 12 days.Therefore, Brian kept the book with him for 12 days.

Question: 1. What is the value of x? Show your work to justify your answer. (2 points) 2. What is the value of the exterior angle? Show your work to justify your answer. (2 points)
Answer:
x=56 and the exterior angle is 116
Step-by-step explanation:
We will call the unknown angle in the triangle y. Angle y and the angle (2x +4) form a straight line so they make 180 degrees.
y + 2x+4 =180
Solve for y by subtracting 2x+4 from each side.
y + 2x+4 - (2x+4) =180 - (2x+4)
y = 180-2x-4
y = 176-2x
The three angles of a triangle add to 180 degrees
x+ y+ 60 = 180
x+ (176-2x)+60 = 180
Combine like terms
-x +236=180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply each side by -1
-1*-x = -56*-1
x=56
The exterior angle is 2x+4. Substitute x=56 into the equation.
2(56)+4
112+4
116

The liquid height in the new cylinder will be 4 cm after the volume of liquid from the original cylinder is transferred.
Explanation:In the context of this problem, we are dealing with the concept of the volume of a cylinder. The volume of a cylinder is given by the formula V=πr²h, where r is the radius of the base and h is the height of the cylinder. The given volume in the problem is 36π cm³ and the radius of the second cylinder is 3 cm. We will use the volume formula to find the height.
We know that V=36π cm³ and r=3 cm. Substituting these values into the volume formula, we get 36π=π(3)²h. Simplifying the equation gives us 36π=9πh. Dividing both sides by 9π, we arrive at the solution, h=4 cm. Therefore, the height of the liquid in the new cylinder will be 4 cm.

In 1983 the composition of pennies in the United States was changed due, in part, to the rising cost of copper. Pennies minted after 1983 weigh 2.50 grams while the earlier copper pennies weigh 3.11 grams. a. A roll of pennies contains 50 pennies. If a particular roll of pennies weighs 138.42 grams, how many of the earlier copper pennies and how many of the after 1983 pennies does this roll contain? b. Suppose you measure a roll of pennies on a scale which only reads the weight to the nearest gram. The scale says that the roll of pennies weighs 131 grams. What can you conclude about the pennies in this roll? What if the roll weights 134 grams? Explain.
Answer:
Solution for (a)
Earlier Copper pennies are 22.
After 1983 pennies are 28.
Step-by-step explanation:
Pennies minted after 1983 weigh 2.50g
Earlier copper pennies weigh 3.11g
A roll of pennies contains 50 pennies.
A particular roll of pennies weighs 138.42g
Let the number of pennies minted after 1983 be x and;
Earlier copper pennies be 50 - x
2.50x + 3.11(50 - x) = 138.42
Opening the brackets gives;
2.5x + 155.5 - 3.11x = 138.42
Solving like terms together gives;
-0.61x = -17.08
Dividing through gives;
x = 28
So there are 28 after 1983 pennies and;
50 - 28 = 22 earlier pennies.
