Which figure has a greater volume and by how much?
The volume of figure 1 is 45 centimeters cubed greater than the volume of figure 2.
The volume of figure 2 is 45 centimeters cubed greater than the volume of figure 1.
The volume of figure 1 is 120 centimeters cubed greater than the volume of figure 2.
The volume of figure 2 is 120 centimeters cubed greater than the volume of figure 1.
Answer:
A) The volume of figure 1 is 45 cm³ greater than the volume of figure 2
Step-by-step explanation:
Let's start by calculating the volumes of both figures
Figure 1
Rectangular prism
V = Bh
V = (15*6)(5)
V = (90)(5)
V = 450 cm³
Triangular prism
V = Bh
V = 1/2(3*15)(6)
V = 1/2(45)(6)
V = 1/2(270)
V = 135 cm³
Add them together, you get 585 cm³
Figure 2
Rectangular prism
V = Bh
V = (6*15)(5)
V = (90)(5)
V = 450 cm³
Rectangular pyramid
V = 1/3 Bh
V = 1/3 (15*6)(3)
V = 1/3 (90)(3)
V = 1/3 (270)
V = 90 cm³
Add them together, you get 540 cm³
Subtract 540 from 585 and get 45
Answer:
A) The volume of figure 1 is 45 cm³ greater than the volume of figure 2
Step-by-step explanation:
Find two numbers, if their sum is 93 and their difference is 9.
Answer:
51 and 42
Step-by-step explanation:
Use
x + y = 93
x - y = 9
Add those two equations together and you get 2x = 102
*y is not in the equation anymore because y + -y = 0*
Divide both sides by 2
x = 51
plug x into one of the equations; let's use x + y = 93
Then you get, 51 + y = 93
Subtract both sides by 51 and you get y = 42
Plug both in the other equation to make sure the numbers work.
51 + 42 = 93; true
51 - 42 = 9; true
Answer:

If each balloon holds 2 oz of water, you can multiply 19 by 2 to find out how many ounces you'll need. 19*2 is equal to 38, but rounding up is 40.
The total amount of water needed by Pat for the balloon fight is 40 ounces.
The correct option is (A).
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers and their relationships.
As per the given data:
The number of balloons needed for a fight is equal to 19.
The amount of water each water balloon holds is also given.
We have to find out the total amount of water needed by Pat for the balloon fight.
The amount of water each water balloon holds = 2 ounces
Total amount of water needed by Pat for the balloon fight:
= number of balloons needed for a fight × amount of water each water balloon holds
= 19 × 2
= 38 ounces (after rounding off to the tenths place, it's equal to 40)
= 40 ounces

A chef at a restaurant uses 14 pounds of butter each day. About how many grams of butter does the chef use each day Start Fraction 16 ounces Over 1 pound End Fraction
and Start Fraction 28.4 grams Over 1 ounce End Fraction
Answer:
6361.6 grams
Step-by-step explanation:
A chef at a restaurant uses 14 pounds of butter each day
Given;
16 ounces per pound
And
28.4 grams per ounces
Converting 14 pounds to gram;
14 pounds × 16 ounces/pound = 224 ounces
Then;
224 ounces × 28.4 grams/ounce = 6361.6 grams
1/2(b+14)=b+14/2. What is the solution to this
The equation 1/2(b + 14) = b + 14/2 simplifies to 14 = 14, suggesting that any value for b is a solution, and the equation is an identity.
The given equation is 1/2(b + 14) = b + 14/2. To solve for the variable b, we can perform algebraic operations. First, we recognize that the equation on the left side is already simplified, but we need to clarify whether the denominator 2 applies to the whole right-hand side or just to the 14 in the equation b + 14/2. Assuming it applies only to the 14, we can multiply both sides of the equation by 2 to eliminate the denominators:
1/2(b + 14) * 2 = (b + 14/2) * 2b + 14 = 2b + 14After simplifying, we see that b on both sides cancels out, leaving us with an equality 14 = 14, which is always true. This means that the equation has infinitely many solutions, since any value of b will satisfy the equation. If the denominator 2 applied to the entire right-hand side (b + 14), then the equation is already balanced as written, again indicating that any value of b would be a solution.
This balance shows that the original equation represents an identity rather than a conditional equation with a specific solution.
The unit of measure of the of the conversion factor should be the unit of
measure which you want to convert.
The correct use of conversion factors will result in the cancellation of the unwanted units and retention of the desired unit.
Conversion factors are essential in unit conversions, allowing us to switch from one unit of measurement to another within the same system, such as U.S. customary units or the SI unit system. To use conversion factors effectively, one must ensure that the unit of measure they wish to convert from or to is correctly positioned in the conversion factor equation. For instance, when converting meters to centimeters, a factor of 1 cm/10-2 m or 100 cm/1 m is used because 'centi' means 10-2 in the SI unit system.
It is important to keep track of units being canceled during the conversion. If you have units in the numerator and denominator that are the same, they will cancel out, leaving only the desired unit. In the process of conversion, if the unit you want to convert is in the denominator of the original quantity, the conversion factor should have that unit in the numerator.
Choosing the right conversion factor and accurately performing the calculations are crucial. A proper conversion factor will cancel out unwanted units. Using an incorrect conversion factor without an opposing unit to cancel out will leave an unwanted unit in your answer, indicating an error in the process.
Dimensional analysis, which often involves conversion factors, simplifies the process of converting units and ensures that measurements within calculations are consistent. This technique is fundamental for scientific calculations and everyday applications, such as determining the appropriate unit to measure large volumes or distances.

The sum of two consecutive even numbers is 206. What is the value of the smallest number?
Answer:
102
Step-by-step explanation:
Since we know that the numbers are two consecutive even numbers, we can write an equation like this where n represents the 2 numbers.
n + (n+2) = 206
Simplify the left side:
n + (n+2) = 206 -----> 2n+2 = 206
Subtract 2 from both sides:
2n = 206-2 -----> 2n = 204
Now divide 204 by 2:
n = 204/2 -----> n = 102
The smallest of two consecutive even numbers, whose sum is 206, is 102.
Explanation:The question is asking for the smallest of two consecutive even numbers whose sum is 206. Let’s denote the smaller even number by n. The next consecutive even number would be n+2 (since even numbers are two units apart).
The problem states that the sum of these two numbers is 206 which can be written in the equation form as n + (n+2) = 206. It simplifies to 2n + 2 = 206. Subtracting 2 from both sides, we get 2n = 204. And finally, dividing by 2, we find that n = 102. So, the smallest number is 102.

A delivery company has 18 vehicles in its fleet. it has 8 vans and 10 trucks All 18 vehicles are on the road every working day The company is reviewing its fuel expenses and therefore gathers some information about each type of vehicle VAN=> average distance travelled per day (in km) is 198 and its average distance travelled per litre is 9 TRUCK=>average distance travelled per day (in km) is 620 and its average distance travelled per litre is 6.2 All the vehicles use the same type of fuel at £1.29 per litre Use this information to work out the bill for 1 working day. You must show all of your working
Answer:
$157.38 per day is used.
Step-by-step explanation:
Van distance 198
9km per L
198÷9=22L
Truck distance 620
6.2km per L
620÷6.2=100L
truck 100L
+van 22L
=122Lx1.29
=157.38
Daily fuel consumption is calculated for trucks and vans by dividing their respective average distances travelled per day by their averages distances travelled per litre. These amounts are multiplied by the respective numbers of each vehicle and then by the cost of fuel (£1.29 per litre) to give a total daily fuel bill of £1,517.04.
Explanation:The first step in calculating the daily bill for the delivery company is to determine how many litres of fuel both the vans and trucks consume per day. To do this, divide the average distance travelled per day by the average distance travelled per litre for each type of vehicle.
For the vans, this would be 198 / 9 = 22 litres per day. For the trucks, 620 / 6.2 = 100 litres per day.
The company has 8 vans and 10 trucks, so the total daily fuel consumption would be: (8 * 22) + (10 * 100) = 176 + 1000 = 1176 litres.
The cost of fuel is £1.29 per litre, so the daily bill would be 1176 * £1.29 = £1,517.04.
Therefore, the delivery company's total fuel bill for one working day is £1,517.04.
