help!! i don’t understand geometry

Answer:

2n^2 + n + 4.

Step-by-step explanation:

7, 14, 25, 40, 59

The differences  are 7, 11, 15, 19 which is  arithmetic sequence so the given sequence is quadratic.

Compile a table:

n                     1      2      3      4      5

term               7    14    25    40    59

Diff:                    7      11     15     19

Diff:                      4       4      4            - this indicates that first part is 2n^2.

2n^2               2    8    18    32     50

term-2n^2      5    6    7     8        9

- the nth term for the last sequence is  5+ (n - 1)d =  

= 5 + (n - 1)* 1

= n + 4.

So nth term for the original sequence is 2n^2 + n + 4.

Answer:

35% of 15=35/100×15=21/4=5.25

Answer:

14.4

Step-by-step explanation:

Area= 72 cm^2

Base= 10 cm

height= ?

Area= base x 1/2 x height

72 = 10 x 1/2 x h

72= 5 x h

72/5 = h

h= 14.4

3) x= 331

Step-by-step explanation:

Answer:

[tex]y = 5 + x[/tex]

[tex]y - x = 5[/tex]

[tex]x = y - 5[/tex]

Step-by-step explanation:

No options were given but the question can still be solved

Given

From the first statement, we have:

[tex]Maria = x[/tex]

From the second, we have:

[tex]Anika = 5\ more[/tex]

Required

Determine the relationship between the amount of rice they bought

5 more means 5 + Maria.

So, [tex]Anika = 5\ more[/tex] becomes

[tex]Anika = 5 + Maria[/tex]

Substitute x for Maria

[tex]Anika = 5 + x[/tex]

For proper expression, let Anika be y

[tex]y = 5 + x[/tex]

Subtract x from both sides

[tex]y - x = 5[/tex]

Make x the subject

[tex]x = y - 5[/tex]

Answer:

XVW and WVT

Step-by-step explanation:

Two angles are supplementary angles when the sum of their measures is equaled to 180 degrees.

180 degrees = a line.

YVZ and WVU are Vertical Angles

YVZ and ZVT are not straight lines together.

XVW and WVU are on the same straight line but you have to add UVT in order to get 180.  

XVW and WVT are the only ones that look like they can add up to 180 degrees.

XVW and WVT should be the answer, I really hope this helps!

Answer:

The least they will have to pay is 235 dollars.

They will have to pay 15 more dollars next year. (250 dollars)

Step-by-step explanation:

25x3=75

40x4=160

75+160=235

25x2=50

40x5=200

50+200=250

Answer: She can read 1.2 chapters of her book in one hour.

Step-by-step explanation:

When we have a relation of: "doing something" in a given "amount of time"

The rate at which you can do that activity per unit of time is:

R = (how much you did)/(time it took)

In this case, we know that

"Tory reads 4/5 of a chapter in 2/3 of an hour"

Then the rate, in this case, could be calculated as:

R = (4/5 chapters)/(2/3 hour) = 1.2 chapter per hour.

This means she can read 1.2 chapters of her book in one hour.

Answer:

the top answer

Step-by-step explanation:

Answer:

6. p = 4

7. m = 7

8. n = 13

9. z = 5

10. x = 4

11. y = 9

Step-by-step explanation:

You can divide the solution by the number next to the letters/variables.

For example, to find 9p = 36 you can do 36 ÷ 9 which equals 4.

To double check, you can multiply your quotient by the divisor.

So to check if p = 4, you can do 9 x 4 which equals 36, therefore it is the solution.

Given:

In a right angled triangle ABC the perpendicular and the base measure 3 cm.

To find:

The hypotenuse and three trigonometric ratios.

Solution:

Pythagoras theorem:

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

Use Pythagoras theorem in triangle ABC.

[tex]Hypotenuse^2=(3)^2+(3)^2[/tex]

[tex]Hypotenuse^2=9+9[/tex]

[tex]Hypotenuse=\sqrt{18}[/tex]

[tex]Hypotenuse=3\sqrt{2}[/tex]

The three trigonometric ratios are

[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin \theta=\dfrac{3}{3\sqrt{2}}[/tex]

[tex]\sin \theta=\dfrac{1}{\sqrt{2}}[/tex]

Similarly,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos \theta=\dfrac{3}{3\sqrt{2}}[/tex]

[tex]\cos \theta=\dfrac{1}{\sqrt{2}}[/tex]

And,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\tan \theta=\dfrac{3}{3}[/tex]

[tex]\tan \theta=1[/tex]

Therefore, the hypotenuse is [tex]3\sqrt{2}[/tex] cm and three trigonometric ratios are [tex]\sin \theta=\dfrac{1}{\sqrt{2}}, \cos \theta=\dfrac{1}{\sqrt{2}}, \tan \theta=1[/tex].

Answer:

Only Cory is correct

Step-by-step explanation:

The gravitational pull of the Earth on a person or object is given by Newton's law of gravitation as follows;

[tex]F =G\times \dfrac{M \cdot m}{r^{2}}[/tex]

Where;

G = The universal gravitational constant

M = The mass of one object

m = The mass of the other object

r = The distance between the centers of the two objects

For the gravitational pull of the Earth on a person, when the person is standing on the Earth's surface, r = R = The radius of the Earth ≈ 6,371 km

Therefore, for an astronaut in the international Space Station, r = 6,800 km

The ratio of the gravitational pull on the surface of the Earth, F₁, and the gravitational pull on an astronaut at the international space station, F₂, is therefore given as follows;

[tex]\dfrac{F_1}{F_2} = \dfrac{ \dfrac{M \cdot m}{R^{2}}}{\dfrac{M \cdot m}{r^{2}}} = \dfrac{r^2}{R^2} = \dfrac{(6,800 \ km)^2}{(6,371 \ km)^2} \approx 1.14[/tex]

∴ F₁ ≈ 1.14 × F₂

F₂ ≈ 0.8778 × F₁

Therefore, the gravitational pull on the astronaut by virtue of the distance from the center of the Earth, F₂ is approximately 88% of the gravitational pull on a person of similar mass on Earth

However, the International Space Station is moving in its orbit around the Earth at an orbiting speed enough to prevent the Space Station from falling to the Earth such that the Space Station falls around the Earth because of the curved shape of the gravitational attraction, such that the astronaut are constantly falling (similar to falling from height) and appear not to experience gravity

Therefore, Cory is correct, the astronauts in the International Space Station, 6,800 km from the Earth's center, are not too far to experience gravity.

Answer:

61 ounces

Step-by-step explanation:

1 pound = 16 ounces

8 pound 3 ounces = 8*16 + 3 = 128 +3 = 131 ounces

No Jesse's weight = 12 pounds = 12*16 = 192 ounces

Weight gained = 192 - 131 =  61 ounces

Answer:

3. [tex]\frac{20}{100}[/tex] and [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Someone already answered b, c, and 2 so here's the third answer :)

10:50 is a ratio, which can be rewritten as [tex]\frac{10}{50}[/tex]

To write an equivalent fraction, we can either multiply or divide.

Multiplying both the numerator and denominator by 2 gets us [tex]\frac{20}{100}[/tex].

Dividing both the numerator and denominator by 10 gets us [tex]\frac{1}{5}[/tex].

Hope this helps!
