Answer:

x = 240

A = 30 m, B = 60 m, C= 90 m

Step-by-step explanation:

a) Nosotros debemos determinar un numero;

para cual [tex]\dfrac{1}{4}x = 60[/tex]

[tex]0.25 x = 60[/tex]

Divide ambos lados entre 0.25; tenemos :

[tex]\dfrac{0.25 x}{0.25}= \dfrac{60}{0.25}[/tex]

x = 240

b) A 180 m se corta en tres piezas A, B y C

Entonces;

Si la pieza B y la pieza C miden el doble y el triple de esa pieza A, respectivamente. Entonces; tenemos

x + 2x + 3x = 180

6x = 180

Divide ambos lados entre 6; tenemos:

[tex]\dfrac{6x}{6} = \dfrac{180}{6}[/tex]

x = 30 m

Si A = x = 30 m

B = 2x = 2×30 m = 60 m

C = 3x = 3×30 m = 90 m

Así; A = 30 m, B = 60 m, C= 90 m

Answer:

1 : 3

Step-by-step explanation:

¼ of the biscuits are chocolate while the rest are plain.

Since a fraction is a part of a whole, 1, then it means that the fraction that are plain is:

1 - ¼ = ¾

Therefore, the ratio of chocolate biscuits to plain biscuits is:

¼ : ¾

To put this in simplest dorm, multiply both sides by 4, we have:

1 : 3

This is the ratio of chocolate biscuits to plain biscuits.

The ratio of the numbers of the chocolate biscuits to plain biscuits to its simplest form is [tex]\mathbf{1:3}[/tex]

In probability, we know that the sum of all the outcomes is usually equal to one.

Given that:

The number of biscuits that are chocolate on the plate is = 1/4

The rest of the biscuits that are plain will be = 1 - 1/4

[tex]= \mathbf{\dfrac{3}{4}}[/tex]

Now, the ratio of the numbers of the chocolate biscuits to plain biscuits to its simplest form is:

[tex]\mathbf{\dfrac{1}{4}:\dfrac{3}{4}}[/tex]

[tex]\mathbf{\dfrac{1}{4} \times \dfrac{4}{3}}[/tex]

= 1 : 3

Answer:

Sorry dude I am a grade 4 that’s too hard

Step-by-step explanation:

Answer:

y = 2x +13

Step-by-step explanation:

when 2 lines are perpendicular, the product of the two gradients is -1

i.e. m x m1 = -1

so from 10y + 5x = 3, the gradient m is -0.5

m1 = -1 / -0.5 = 2

using m1 = 2 and pt(-7,-1),

the eqn is y = (m1)x +c

-1 = 2(-7) + c

c= 13

thus y = 2x +13

Hey there! I'd be delighted to help you out!

First, let's write down our expression!

[tex](x^2-x)+(8x-2x^2)[/tex]

When we look at this expression, we see that all of the numbers are terms, or numbers that are added. We have four terms in this equation, which are:

[tex]x^2, -x, 8x, -2x^2[/tex]

Now, to simplify, we want to combine like terms. Like terms are numbers that have the same variable (or no variable) and are raised to the same power. 1 and 5 are like terms because they both have no variable and they are both raised to the power of 1 (any number that is itself is raised to this power). 4x and 12x are like terms because they both have an x and a power of 1. 4y and 5x are not like terms because they have different variables. 4x³ and 2x² are not like terms because they are raised to different powers.

Now, we see that  with our numbers, x² and -2x² are like terms, and -x and 8x are also like terms. We can combine accordingly.

[tex]x^2-2x^2=-x^2\\\\-x+8x=7x[/tex]

Now we combine to get our simplified expression!

[tex]-x^2+7x[/tex]

Answer:1 and 6

Step-by-step explanation:1 x 6 = 6

1 + (6) = 7

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x2 + 7x + 6 = 0

If so, the solution to factor the quadratic equation above is:

(X + 1 ) (X + 6)

To summarize, since 1 and 6 multiply to 6 and add up 7, you know that the following is true:

x2 + 7x + 6 = (X + 1 ) (X + 6)

Answer:

Respuesta.- La fracción es 9/7

Step-by-step explanation:

1) Llamando X e Y a la fracción, tenemos: X/Y

Si al numerador se le añade 5, es decir X+5, el valor de la fracción es 2, luego:

(X+5)/Y = 2

Y si al numerador se le resta 2, es decir X-2, el valor de la fracción es 1, luego:

(X-2)/Y = 1

Juntando amabas ecuaciones:

(X+5)/Y= 2

(X-2)/Y = 1

Despejando Y en ambas:

Y = (X+5)/2

Y = (X-2)..........(1)

Igualandolas:

(X+5)/2= (X-2)

De donde:

X+5 = 2X-4

X = 9

Y finalmente, sustituyendo el valor de X = 9 en la ecuaión (1), tendremos:

Y = (X-2)

Y = (9-2)

Y = 7

Respuesta.- La fracción es 9/7

Answer:

y = 3x - 10

Step-by-step explanation:

Answer:

y = 3x -10

Step-by-step explanation:

Slope intercept form is y = mx+b  where m is the slope and b is the y intercept

-9x +3y =-30

Add 9x from each side

-9x+9x +3y =9x-30

3y = 9x-30

Divide each side by 3

3y/3 = 9x/3 -30/3

y = 3x -10

~savannah:))

If there are 125 sheep and 5 dogs in a flock  then the shepherd is 25 years old.

A division is a process of splitting a specific amount into equal parts.

Given,

The number of sheeps are 125

One hundred twenty five

The number of dogs are 5

Five.

We need to find how old is the shepherd

To find this we just need to divide one hundred twenty five by five

125/5

25

Hence, if there are 125 sheep and 5 dogs in a flock  then the shepherd is 25 years old.

Answer:

225

Step-by-step explanation:

first the square

9*9 = 81

then the triangle

a is 8

triangles are l*w/2 so 8*4.5/2

8*4.5 = 36/2 = 18

There are 8 of these triangles

18*8 is 144

144+81 = 225

The surface area of the square pyramid is approximately `196` square cm.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

We can use the Pythagorean theorem to find the slant height of the pyramid:

[tex]$$l = \sqrt{a^2 + \left(\frac{b}{2}\right)^2} \\= \sqrt{8^2 + \left(\frac{9}{2}\right)^2} \\= \sqrt{64+\frac{81}{4}} \\= \frac{\sqrt{433}}{2}$$[/tex]

So, the lateral area of the pyramid is the area of the four triangles with base `b` and height `l`, which is:

[tex]$$A_{lat} = 4\cdot\frac{1}{2}b\cdot l \\= 4\cdot\frac{1}{2}\cdot 9 \cdot \frac{\sqrt{433}}{2} \\= 27\sqrt{433}$$[/tex]

So, The area of the base of the pyramid is a² then

[tex]$$A = A_{lat} + a^2$$[/tex]

=  = 27√433 + 8²

= 27√{433} + 64

= 196.4 cm²

Therefore, the surface area of the square pyramid is approximately `196` square cm.

Answer:

Tyson had the better deal

Step-by-step explanation:

We simply want to know who paid less for the ticket.

Tyson bought 8 tickets for the members of his basketball team and it cost it $168 in total.

The cost of each ticket is therefore:

168 / 8 = $21

He paid $21 for each ticket.

The parent bought her son's ticket for $24.

Therefore, Tyson had the better deal because he paid $3 less than the woman.
