PLEASE HELP ME!!! I'M ALMOST OUT OF TIME!!

Answer:

You do need to be more specific, the volume of a sphere is V = 4/3 π r^3, it does not need to be related to a cylinder. So if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3.

Answer:

Obtuse triangle

Step-by-step explanation:

Given the side lengths :

3, 9, 10

Let :

a = 3 ; b = 9 ; c = 10 (longest side)

If a² + b² = c² (right angle)

If a² + b² > c² (acute angle)

If a² + b² < c² (obtuse angle)

a² + b²

3² + 9²

9 + 81 = 90

c² = 10² = 100

90 < 100

Hence,

a² + b² < c² (then we have an obtuse triangle)

Given:

Amy spent $90 at the store.

She spent [tex]\dfrac{1}{3}[/tex] of her money on food, [tex]\dfrac{1}{6}[/tex] of her money on school supplies, and [tex]\dfrac{1}{9}[/tex] of her money on soda.

To find:

How much did she spend on school supplies?

Solution:

According to the given information, Amy spend [tex]\dfrac{1}{6}[/tex] of her money on school supplies.

Amy spent $90 at the store. So,

Money spend on school supplies = [tex]\dfrac{1}{6}\times 90[/tex]

                                                        = [tex]15[/tex]

Therefore, Amy spend $15 on school supplies.

Rectangular prism is also called cuboid.

Formula :

[tex] \longmapsto [/tex] Volume = (18 × 2) feet[tex]\sf ^3 [/tex]

7. R=income/hours worked so 221/17=13. Not sure if that is what they are asking for.

8. Not sure. Is it $13/hour?

9. still guessing but the constant is $13/hour so to determine how many hours need to be worked to reach $1000, you divide. $1000/13=Approximately 77 hours.

Answer:

Final amount after 11 years = $4021.97

Step-by-step explanation:

We will use the formula to get the final amount after t years,

Final amount = [tex]a(1+\frac{r}{n})^{nt}[/tex]

here a = Initial amount

r = Rate of interest

n = Number of compounding in a year

For Initial amount 'a' = $1500

r = 9%

t = 11 years

n = 12 [Compounded monthly]

F = [tex]1500(1+\frac{9}{12})^{12\times 11}[/tex]

  = $4021.97

Answer: D- a reflection of ^RST across the line y=-x

Step-by-step explanation:

The solution is, O a reflection of RST across the line y=-x, is the reflection which will produce an image of RST with a vertex at (2, -3).

Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point.

here, we have,

from the given figure,

we get,

Triangle RST has,

vertex R ( -1,3)

vertex S ( 3, -2)

vertex t (1, -4)

now we know that,

the rule of a reflection across the line y=-x,

(x, y) ⇒ (-x, -y)

so, we get, here,

vertex S ( 3, -2) ⇒ vertex at (2, -3)

so, there is  O a reflection of RST across the line y=-x.

Answer:

Without the math: 65 hours is 5 half-lives

13 hrs = 1/2

26 hrs = 1/4

39 hrs = 1/8

65 hrs = 1/32

(1/2)^5 = 1/32

400 mg / 32 = 12.5 mg   that is, after 5 half-lives

Answer:

x = 6

y = 45 degrees

Step-by-step explanation:

Here, we want to get the measure of x and y

For a 45-45-90 triangle, the measure of each of the internal angle asides the right angle is 45 degrees

This mean y is 45

To get x, we know we have an isosceles triangle

So the length of the third ungiven leg is x too

Mathematically, the square of the hypotenuse (side facing the right angle) is equal the sum of the squares of the two other sides

(6 √2)^2 = x^2 + x^2

72 = 2x^2

x^2 = 72/2

x^2 = 36

x = √36

x = 6

Answer:

area = 73.37 cm²

Step-by-step explanation:

area of circle:

A = π5² = 78.5 cm²

area of 80° segment:

(80/360)(78.5) = 17.44 cm²

area of isosceles triangle w/ 5 cm legs and 80° angle:

sin 40° = b/5

0.6428 = b/5

b = 3.214

base = 2(3.21) = 6.43   (we only figured for one-half of the base)

cos 40° = h/5

0.7660 = h/5

height = 3.83

A = 1/2(6.43)(3.83) = 12.31 cm²

area of unshaded part:

17.44 - 12.31 = 5.13 cm²

area of total shaded part:

78.5 - 5.13 = 73.37 cm²

A = 10 months

B = First part, the two equations:

Ian: y = 1000 - 60x, where x is the number of months and y is the remaining balance owed.

Ken: y = 600 - 20x.

They will be equal at 1000 - 60x = 600 - 20x

Second part: Solve the equation. Note, if you're equation is incorrect, solve it anyway because you will still get some credit!

1000 - 60x = 600 - 20x

1000 = 600 + 40x

400 = 40x

x = 10 months

y = 600 - 20(10) = 600 - 200 = $400 still owed.

C =

Solve Ian's equation for y = 0, when no money is owed.

1000 - 60x = 0

1000 = 60x

x = 16.66666.... or 17 months.

Ian will not be paid off 6 months after he and Ken owe the same amount. He will still owe money.

Alternatively, six months after 10 is 16 months,

and y = 1000 - 60(16) = 1000 - 960 = 40. He will still owe $40 at 16 months, so he is not paid off.

Answer:

[tex]x=96[/tex]

Step-by-step explanation:

[tex]360=x+\left(x+90\right)+\left(x-18\right)[/tex]

Step 1: Simplify both sides of the equation.

[tex]360=x+x+90+x-18[/tex]

[tex]360=(x+x+x)+(90+-18)[/tex] (Combine Like Terms)

[tex]360=3x+72[/tex]

Step 2: Flip the equation.

[tex]3x+72=360[/tex]

Step 3: Subtract 72 from both sides.

[tex]3x+72-72=360-72[/tex]

[tex]3x=288[/tex]

Step 4: Divide both sides by 3.

[tex]\frac{3x}{3}=\frac{28}{3}[/tex]

[tex]x=96[/tex]
