help me please.. im doing 8th grade math with pythagorean theorem i really need help please 10 points!!

Answer:

Radian angle = 1.154

Central angle = 66.123°

Step-by-step explanation:

Area of Sector, A

A = 1/2 * r² * θ ; θ measured in radian

A = 9 π

r = 7

9 π = 1/2 * 7² * θ

9 π = 24.5θ

θ = 9 π / 24.5

θ = 1.154 radian

1 radian = 57.296°

1.154 radian = (57.296 * 1.154)

1.154 radian = 66.123°

Answer:

quadrilateral and parallelogram

Step-by-step explanation:

since it has 4 sides and 4 angles it is quadrilateral and since there are two sets of parallel lines connected and each pair has different lengths, it should be parallelogram

Answer:

[tex]Persephone = 27\frac{3}{7}[/tex]

[tex]Madison = 20\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]Pages = 48[/tex]

[tex]P=8\ mins[/tex] --- Persephone

[tex]M = 6\ mins[/tex] --- Madison

The question is incomplete, however a possible question could be:

To determine the number of pages colored by each of them

First, we determine the ratio of time spent by each:

[tex]P : M = 8 : 6[/tex]

The number of pages covered by Persephone is:

[tex]Persephone = \frac{P}{P + M} * Pages[/tex]

[tex]Persephone = \frac{8}{8+6} * 48[/tex]

[tex]Persephone = \frac{8}{14} * 48[/tex]

[tex]Persephone = \frac{384}{14}[/tex]

Simplify

[tex]Persephone = 27\frac{3}{7}[/tex]

This implies that Madison colors the remaining pages.

This is calculated as:

[tex]Madison = Pages - Persephone[/tex]

[tex]Madison = 48 - \frac{384}{14}[/tex]

Take LCM

[tex]Madison = \frac{48 * 14 - 384}{14}[/tex]

[tex]Madison = \frac{288}{14}[/tex]

Simplify

[tex]Madison = 20\frac{4}{7}[/tex]

Step-by-step explanation:

I just know

Answer:

$50

Step-by-step explanation:

Given data

Cost of sushi= $40

Tax= 5%

Tip= 20%

Let us find the amount of the tax and the tip

Tax

=5/100*40

=0.05*40

=$2

Tip

=20/100*40

=0.2*40

=$8

Hence the total amount paid is

=40+2+8

=$50

Answer:

$50

Step-by-step explanation:

To avoid confusion, we can solve for the sales tax and the tip separately.

Tip

Tax

Total

Answer:

2.5 years/2 years 6 months

Step-by-step explanation:

Half year = 6 months

One year = 12 months

Two years = 24 months

30-24=6 months

2 Years + 6 months = 2.5 years/30 months/2 years 6 months

Answer:A

Answer:

Vertical angles are across from each other on any two intersecting lines and are always congruen

Answer:

Option 3

Step-by-step explanation:

By applying Pythagoras theorem in the given triangle,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

x² = (9.5)² + (10.5)²

x² = 200.5

x = √(200.5)

x = 14.16

x ≈ 14.2

Therefore, measure of the unknown side is 14.2 in.

Option (3) will be the correct option.

Answer:

$5,035

Step-by-step explanation:

First, you have $400 as the first cost in the closing costs.

You Then find 1.5% of the loan amount, which is 70% of $400,000 ($280,000), so 1.5% of $280,000 is $4,200. So you add $4,200 to the $400

Next, you add the notary fee of $60.

Then you add the recording fees of $75.

Lastly, you add the title search of $300.

Now add everything up, $400 + $4,200 + $60 + $75 + $300 = $5,035

Final answer = $5,035

Answer:

61, 63, 65

Step-by-step explanation:

n + n+2 + n+4 = 189

3n = 183

n = 61

Answer:

The three consecutive odd integers are 61, 63, and 65

Step-by-step explanation:

Let the three consecutive odd integers be:

n + 1, n + 3 and n + 5

Therefore:

n + 1 + n + 3 + n + 5 = 189

3n + 9 = 189

3n = 180

n = 60

n + 1 = 61

n + 3 = 63

n + 5 = 65

Answer:

They will mirror each other, but only if they have the same y value. Otherwise they will simply be on opposite sides of the Y line.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

I am assuming that this ball is a perfect sphere.

The volume of a sphere is [tex]\frac{4}{3} *\pi *r^3[/tex]

We have the diameter, and in order to find the radius, we just have to divide by 2. 6/2=3. Now, we have to plug in the 3 to the equation.

[tex]\frac{4}{3} *\pi *3^3[/tex]

3 cubed is 27, so now we have [tex]\frac{4}{3} *\pi *27[/tex]

27*4/3*pi=36pi

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

To calculate the future value, we need to use the following formula:

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12
