What is the volume of the pyramid?
12 in
8 in
10 in
120 in
320 in
480 in
960 in
Answers
Answer:
B. 320 inches cubed
Step-by-step explanation:
A pyramid's volume is denoted by: V = (1/3) * B * h, where B is the base area and h is the height.
Here, the base is a rectangle with dimensions 10 inches by 8 inches. The area of a rectangle is denoted by: A = lw, where l is the length and w is the width. The length is 8 and the width is 10, so plug these in:
A = lw
A = 8 * 10 = 80
So, we know that B = 80.
We are also given that the height is h = 12, so plug these values into the volume formula:
V = (1/3) * B * h
V = (1/3) * 80 * 12 = 320
The answer is thus B.

Jose starts with $250 and spends $25 a week. Martin starts with $30 and saves $30 a week. When do Jose and Martin have the
same amount of money? Use x for time and y for saving.
Answers
Answer:
4 weeks, Jose and Martin will have the same amount of money in 4 weeks which is $150 each
Step-by-step explanation:
Jose:
y = -25x +250
Martin:
y=30x+30
Substitute x= 6 into the two equations
Jose:
y = -25(6) + 250
= -150+250
y = 100
Martin:
y = 30(6) +30
=180+30
y = 2100
Substitute x=4 into the two equations
Jose:
y = -25(4) + 250
=-100+250
y = 150
Martin:
y = 30(4) + 30
=120+30
y = 150
A contractor bought 8.2 ftsquared of sheet metal. She has used 3.5 ftsquared so far and has $141 worth of sheet metal remaining. The equation 8.2xminus3.5xequals141 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answers
Answer:
The cost of a sheet metal per square foot is $30
Step-by-step explanation:
Given
Size of Sheet Metal = 8.2ft squared
Used Sheet Metal = 3.5ft squared
Worth of leftover sheet = $141
Equation: [tex]8.2x - 3.5x = 141[/tex]
Required
Find the cost per square foot of the sheet metal
Solving for x in the above equation will give the cost per square foot of the sheet metal.
[tex]8.2x - 3.5x = 141[/tex]
[tex]4.7x = 141[/tex]
Divide both sides by 4.7
[tex]\frac{4.7x}{4.7} = \frac{141}{4.7}[/tex]
[tex]x = \frac{141}{4.7}[/tex]
[tex]x = 30[/tex]
Hence, the cost of a sheet metal per square foot is $30

Given Data:
Red ball = 11
Blue ball = 7
Total no of balls = 18
What is the probability that choosing 4 balls all are red.
1. Probability of picking a red ball
= 11/18
2. Probability of picking a blue ball
= 7/18
3. Probability of picking 4 red balls in a roll.
= 11/ 18 * 10/17 * 916 * 8/15
= 11/102

Amanda is making flower arrangements. She has 20 daisies and 16 roses. Each arrangements must hhave the same number of daises and same number of roses. She wants to use all the flowers. What is the greatest number of arrangements she can make? How many daisies and how many roses will be in each?
Answers
Answer:
The greatest number of arrangements she can make would be that she uses 4 groups of 5 daisies and 4 groups of 4 roses.
The greatest number of arrangements is 4, and each group has 5 daises and 4 roses.
What is the greatest common divisor?The biggest positive integer that divides both numbers and is a divisor of both is known as the greatest common divisor of two integers.
Given that, Amanda has 20 daises and 16 roses.
The number of arrangements that can be made using 20 daises and 16 roses is the greatest number that can divide both the numbers 20 and 16.
The greatest number that can divide both 20 and 16 is 4.
Hence, 4 groups of arrangements can be made.
The number of daises in a group is:
20/4
= 5
The number of roses in a group is:
16/4
= 4
Hence, the greatest number of arrangements is 4, and each group has 5 daises and 4 roses.

Un olivar tiene 80 olivos. Sesenta de ellos dan, por término medio, 50 kg 4 hg 60 dag 5 g de aceitunas cada uno, y los otros veinte, 53 kg 2 hg 16 dag 5 g. Si el número de litros de aceite que se obtiene es un quinto de los kilogramos de aceituna que se recogen, calcula la ganancia que obtendremos sabiendo que cada litro de aceite se vende a 2,65 € y que en la recolección nos gastamos 860 €.
Answers
Answer:
1330.808 euros
Step-by-step explanation:
Let's first calculate the total amount of kilograms,
for the first 60, we have to:
50 kg
4 hg = 0.5 kg
60 dag = 0.6
5 g = 0.005 kg
adding: 50 + 0.5 +0.6 + 0.005 = 51.105 kg per tree, but they are 60
51.105 * 60 = 3066.3
now for the other 20:
53 kg
2 hg = 0.2 kg
16 dag = 0.16
5 g = 0.005
adding: 53 + 0.2 +0.16 + 0.005 = 53.365 kg per tree, but they are 20
53,365 * 20 = 1067.3
in total it would be: 3066.3 + 1067.3 = 4133.6
they tell us that 1/5 is the quantity in liters:
4133.6 * 1/5 = 826.72 liters
so to calculate the earnings it would be:
2.65 * 826.72 - 860 = 1330.808
which means that in net earnings are 1330.808 euross

Use a net to find the surface area of the right triangular prism shown below (Please show how you worked it) :
104 square feet
412 square feet
468 square feet
504 square feet
Answers
Answer:
468 square feet; Option C
Step-by-step explanation:
We can see that the base of this triangular prism has dimensions 15 feet by 10 feet, so for starters let us compute the area of this base:
Area ⇒ 15 * 10 = 150 ft^2
Now the rectangular surface next to this base, has dimensions 9 feet by 10 feet, provided that 9 feet is a uniform height of the triangular prism:
Area ⇒ 9 * 10 = 90 ft^2
This third rectangle is provided with one dimensions, of 10 feet. If we were to imagine what part of the 3-d shape is is, it would in fact be the slanted top. To find the second dimension, you would imagine it to be 12 feet. Using that, the area of this rectangle is thus ⇒ 10 * 12 = 120 ft^2
Now the two triangles at the corners each have an area of ⇒ 1/2 * base * height = 1/2 * 12 * 9 = 6 * 9 = 54 ft^2, so they have a total area of ⇒ 108 ft^2
This means the surface area of the right, triangular prism is:
150 + 90 + 120 + 108 = Answer: 468 square feet

Mr. Whittaker’s science class uses tide gauges to measure annual variations in water levels at different parts of a river, and then compares those variations to the average annual trend.
Matea recorded that the water level in one part of the river fell 1.05 millimeters per year for 2.48 years.
Which number represents the rate at which the water level fell? -1.05mm/year
Which number should the rate be multiplied by to find the total variation in water level?
2.48 years
that's the correct answer ^
This data will be compared to the average annual trend, which shows the water level rising 1.8 mm/year.
Which number represents the rate at which the water level fell?
Which number should the rate be multiplied by to find the total variation in water level?
Answers
Answer:
a) Which number represents the rate at which the water level fell? -1.05mm/year
b) Which number should the rate be multiplied by to find the total variation in water level?
2.48 years
Step-by-step explanation:
Total variation in water level is calculated as the rate at which the water level fell multiplied by number of years are which the water level fell.
Mathematically = Rate at which the water level fell(mm/year) × number of years are which the water level fell (years).
Total variation in water levels can be caused by changes in climate conditions or by human activity.
Hence, for the question above,
rate at which the water level fell is
given as -1.05mm/year and the number that the rate be multiplied by to find the total variation in water level is 2.48 years.
Answer:
Which number represents the rate at which the water level fell?
