caden built a rectangular prism that has a length of 8 units a width of 3 units, and a height of 5 units. what is the volume of the prism. show your work

Answers

Answer 1

Answer: To calculate the volume of a prism you multiply the area of it's cross section by the length Therefore 5 x 3= 15 (Area of the rectangle) 15x8= 120 (Volume of prism)

Answer 2

Answer: Solutions

Caden built a rectangular prism that has a length of 8 units a width of 3 units, and a height of 5 units.To calculate the volume of the prism you have to multiply the area of it's cross section by the length.

5 x 3= 15 (Area)

15 x 8= 120 (Volume of whole prism)

To illustrate the importance of outliers, suppose the 65-year old walks away from the party. Remaining at the party are the five people who are 30 years old, three people that are 32, and one person that is 31.Determine the mean age and standard deviation, to the nearest tenth, of the people who remain at the party.A. The mean age of the remaining people at the party is a0 B. The standard deviation is:

Cho and Jeff each bought a used bike. Jeff's bike was not on sale and cost the same amount as theoriginal price of Cho's bike. Cho's bike was on sale for $20 less than the original price, and her total
cost was half of what Jeff paid. How much money did Jeff pay for his bike?
A. $30
B. $10
C. $20
D. $40

Answers

The right answer for the question that is being asked and shown above is that: "A. $30." Cho's bike was on sale for $20 less than the original price, and her total cost was half of what Jeff paid. Jeff pay A. $30 for his bike

Jeff = x (original price)
Cho = x-20

When i was two, my brother was half my age
now i am 100. what is my brothers age

Answers

When you were 2, your brother were 2/2=1. So you are one year older than your brother.
If you are 100 now, then your brother is 100-1=99.

99 as 2 halved is 1 so 100-1= 99

Marvin walks at a speed of 7 feet per minute. How many miles per hour is this?

Answers

Answer:

$(7)/(88)\ (miles)/(hour)$

$0.08\ (miles)/(hour)$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s ----> the speed

x ----> the distance

y ----> the time

$s=(x)/(y)$

we have

$x=7\ ft$

$y=1\ min$

Remember that

$1\ mile=5,280\ feet$

$1\ hour=60\ minutes$

$x=7\ ft=(7)/(5,280)\ mi$

$y=1\ min=(1)/(60)\ h$

Find out the speed in miles per hout

$s=((7/5,280))/((1/60))=(420)/(5,280)\ (miles)/(hour)$

Simplify

$(7)/(88)\ (miles)/(hour)$

$0.08\ (miles)/(hour)$

Answer & Step-by-step explanation:

Make a fraction using the numerator:

$(48)/(15) =(x)/(y)$

Simplify the fraction. Both the numerator and the denominator are multiples of 3, so divide top and bottom by 3 to the lowest possible integer:

$(16)/(5)$

Insert into the equation:

$(48)/(15)=(16)/(5)$

:Done

In Triangle ABC, which trigonometric ratio has the value a/c?A) tan A
B) cos A
C) tan C
D) cos C
E) sin C

Answers

The answer would be A) tan A, because of SOHCAHTOA (if you don't know this, it means SOH) sin=opposite/hypotenuse, CAH) cos=adjacent/hypotenuse, and TOA) tan=opposite/adjacent).

we know that

In the right triangle ABC

$sin(A)=(BC)/(AC)= (a)/(b)$

$cos(A)=(AB)/(AC)= (c)/(b)$

$tan(A)=(BC)/(AB)= (a)/(c)$

$sin(C)=(AB)/(AC)= (c)/(b)$

$cos(C)=(BC)/(AC)= (a)/(b)$

$tan(C)=(AB)/(BC)= (c)/(a)$

therefore

the answer is the option A

$tan(A)$
