Answer:9

Step-by-step explanation:87-24=63 and 63 divided by 7 equals 9

Answer:

when y rename a fraction, you are finding fraction that have the same value but have different name. these are known as equivalent fraction you can rename fraction million of different ways...As long as you multiply numerator and denominator by same number, you will get and equivalent fraction...

Step-by-step explanation:

for example :5/2

5×2/2×2 , 5×3/2×3 , 5×4/2×4 , 5×5/2×5

ANSWER OF THESE EQUIVALENT NUMBERS ARE :

10/4 , 15/6 , 20/8 , 24/10 ....

Answer:

6.3 in.^2

Step-by-step explanation:

The diameter of the circle is 4 in., so the radius of the circle is 2 in.

[tex] A_{sector} = \dfrac{n}{360^\circ} \pi r^2 [/tex]

The two central angles have a total measure of 60 deg + 110 deg = 170 deg.

The central angle of the shaded sector is 360 deg - 170 deg =  190 deg.

We will use n = 190 deg in the area formula.

[tex] A_{sector} = \dfrac{190^\circ}{360^\circ} \pi (2~in.)^2 [/tex]

[tex] A_{sector} = 6.3~in.^2 [/tex]

Answer:

What do you need though...

A basic rundown since I have no clue what you need help with

Parallelograms

(4 sided shapes that always adds up to 360 degrees if you add all the angles inside with opposite sides parallel)

Squares, rectangles (most common)

Triangles

3 sided figures with all the interior angles being added up equals to 180 degrees. The 3 sides of a triangle can be found with a^2+b^2=c^2.

The properties are 2 legs and 1 hypotenuse. To determine if its a triangle, if the 2 legs added up (two of the shortest sides) they must be greater then the hypotnuse (greatest side).

THese are the two of the most common shapes if you need an huything else just lemme know in the comments.

Answer:

with simplify: 1 4/20.

without simplify: 24/20

Step-by-step explanation:

first we have to find the common denominator

can 4 go into 10? no.

can 4 go into 20? yes! it goes into 20, 5 times!

common denominator = 20

_/20 + _/20

what we do to the bottom we do to the top

7 x 2= 14

14/20 + _/20

2 x 5= 10

14/20 + 10/20 = 24/20

now simplify

1 4/20

hope this helped!

Answer:

expansion

Step-by-step explanation:

I believe that the biggest reason for the general upward trend in the stock price is expansion. Amazon has expanded their company immensely over the last 5 years. They have also expanded into different markets such as drones, gaming, cloud streaming, video streaming, etc. All of these expansions and acquisitions have been incredibly profitable for Amazon and therefore reflect on the stock price. This also gives investors faith that the future of the company will continue growing which causes them to buy more stocks and therefore increase the price.

Answer:

es esto correcto? 25?

Step-by-step explanation:

Answer:

w = 3 cm

l = 8 cm

Step-by-step explanation:

let 'w' = width

let '2 + 2w' = length

P = 2l + 2w

22 = 2(2 + 2w) + 2w

22 = 4 + 4w + 2w

22 = 4 = 6w

18 = 6w

w = 3

length = 2 + 2(3) = 18

Answer:

By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2

Answer:

[tex]y=C(x+3)^2[/tex]

Step-by-step explanation:

We are given:

[tex]\displaystyle (x+3)y^\prime=2y[/tex]

Separation of Variables:

[tex]\displaystyle \frac{1}{y}\frac{dy}{dx}=\frac{2}{x+3}[/tex]

So:

[tex]\displaystyle \frac{dy}{y}=\frac{2}{x+3} \, dx[/tex]

Integrate:

[tex]\displaystyle \int\frac{dy}{y}=\int\frac{2}{x+3}\, dx[/tex]

Integrate:

[tex]\displaystyle \ln|y|=2\ln|x+3|+C[/tex]

Raise both sides to e:

[tex]|y|=e^{2\ln|x+3|+C}[/tex]

Simplify:

[tex]|y|=(e^{\ln|x+3|})^2\cdot e^C[/tex]

So:

[tex]|y|=C|x+3|^2[/tex]

Simplify:

[tex]y=\pm C(x+3)^2=C(x+3)^2[/tex]

Answer:

Step-by-step explanation:

1.

Igneous rock can change into sedimentary rock or into metamorphic rock. ... Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool.

2. The three processes that change one rock to another are crystallization, metamorphism, and erosion, and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes.

3. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock.

Step-by-step explanation:

Answer:

100 cm

Step-by-step explanation:

let x be the height of Beth

and y be the height of Beth's Brother

By 1st Condition

y = 140% * x

y = (140/100) * x

y = 1.4 x ..........................(Eq 1)

By 2nd Condition

y = 140

Put the value of y in the equation 1

140 = 1.4 *x

x = 140 / 1.4

x = 100 cm

Answer:

Let's say that x is sam's age and y is Amy's age

x=y-4

and five years ago:

x-5=(y-5)/2

y-4-5=(y-5)/2

2y-18=y-5

y=13

x=9

then:

sam's age is 9 and Amy's age is 13

Answer:

Sam: 9, Amy: 13

Step-by-step explanation:

So five years ago, lets say Sam was 4, and Amy was 8. That would be half Amy's age. If we add on 5 to Sams age, as it says, Amy would then be 13, and Sam would be 9. This is also four years apart. Thus, the answers are Sam: 9 and Amy: 13
