Step-by-step explanation:

Volume of cuboid is length* breadth" height

Volume of cuboid is length* breadth" height=10*8*6= 480cm³

volume of traingular prism= this I don't know

okay wait...imagine there is other half of the traingle such that it becomes cuboid...now find area of cuboid = 5*5*4= 100

now divide by 2 to get half volume ( one triangular prism)

which is 100/2= 50

Volume of traingular prism= 50cm³

Total volume of figure= 480+50= 530cm³

Angela has 3 more dollars than half of sabrina's money. If Angela has 206 dollars, how much does Sabrina have? Define your varie

yan [13]

A=3+(s/2)
a=206

206=3+(s/2)
minus 3 both sides
203=s/2
times 2/1 both sides
406=s

sabrina=406
to check

206=3+(406/2)
206=3+(203)
206=206

Tony has saved dimes and quarters in his piggy bank he has saved a total of four dollars and has 25 coins how many dimes does he

k0ka [10]

Answer:

15 dimes
10 quarters

Step-by-step explanation:

Let q represent the number of quarters. Then Tony's coin value is ...

0.25q +0.10(25 -q) = 4.00

0.15q +2.50 = 4.00 . . . . . . . . eliminate parentheses, collect terms

0.15q = 1.50 . . . . . . . . . . . . . . subtract 2.50

q = 10 . . . . . . . . . . . . . . . . . . . . divide by the coefficient of q

Then the number of dimes is ...

25 -10 = 15

Tony has 15 dimes and 10 quarters.

Amanda's school is due west of her house and due south of her friend Shereen's house. The distance between the school and Sheree

Blizzard [7]

The Amanda's house is 6.7 km far from her school.

<u>Step-by-step explanation:</u>

From the given information,

The Amanda's school is due west of her house forms the base.
The school is due south of the Shereen's house forms the height.
The straight-line distance between Amanda's house and Shereen's house forms the hypotenuse.

Therefore, It can be determined that it forms the right angle triangle.

It is given that,

The distance between the school and Shereen's house is 2 kilometers.

That is, the height of the triangle = 2 km

The straight-line distance between Amanda's house and Shereen's house is 7 kilometers.

That is, the hypotenuse of the triangle = 7 km

Now, the distance between the Amanda's house and her school is the base of the triangle.

Base = $\sqrt{(hypotenuse)^{2}-(height)^{2} }$

⇒ $\sqrt{(7)^{2} -(2)^{2} }$

⇒ $\sqrt{49-4}$

⇒ $\sqrt{45}$

⇒ 6.7 km

Therefore, the Amanda's house is 6.7 km far from her school.

If a boat with a value of $23, 000 depreciates at a rate of 18% per year, what is the value

Naily [24]

Using an exponential function, it is found that the value of the car after 5 years will be of $8,527.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

For this problem, the initial cost and the decay rate are given as follows:

A(0) = 23000, r = 0.18.

Hence the value of the boat after t years is given as follows:

$A(t) = A(0)(1 - r)^t$

$A(t) = 23000(1 - 0.18)^t$

$A(t) = 23000(0.82)^t$

The value after 5 years will be of:

$A(5) = 23000(0.82)^5 = 8527$

The value of the car after 5 years will be of $8,527.
