Answer:

8

Step-by-step explanation:

a = 4

b = 3

4 / a

= 4 / 4

= 1

b / 3

= 3 / 3

= 1

6 + 4 / a + b / 3

= 6 + 1 + 1

= 8

Answer:

Answer:

48 globos

Step-by-step explanation:

De la pregunta anterior, se nos dice que:

En el cumpleaños de Manolito se inflaron 144 globos.

Por eso:

Para globos rojos

2/9 de los globos eran rojos

Número de globos rojos = 2/9 × 144 globos

= 32 globos

Para globos verdes

5/18 eran verdes

Número de globos verdes = 5/18 × 144 globos

= 40 globos

Para globos amarillos

1/6 eran amarillas

Número de globos amarillos = 1/6 × 144 globos

= 24 globos

Tenga en cuenta que:

Número total de globos =

Globos rojos + Globos verdes + Globos amarillos + Otros colores

Otros colores = 144 globos - (globos rojos + globos verdes + globos amarillos)

Otros colores = 144 globos - (32 + 40 + 24) globos

= 144 globos - 96 globos

= 48 globos

Por lo tanto, la cantidad de globos que son de otros colores = 48 globos

Answer:

-1.1

Step-by-step explanation:

The z-score formula is expressed as;

z = x - m/s

x is the sample size = 495

m is the mean score = 550

s is the standard deviation = 50

Substitute inti the formula;

z = 495 - 550/50

z = = -55/50

z = -11/10

z = -1.1

Hence the z score is -1.1

Answer:

133

Step-by-step explanation:

Because the figure is an irregular figure we need to break it up into two regular figures

The figure would be broken into..

A square with a side length of 4

And a rectangle with a length 13 and a width of 9

We now find the areas of the regular figures and add them together to get our answer

For the square.

To find the area of a square simply square the side length

Area = 4^2 = 16

For the rectangle

to find the area of the rectangle simply multiply the Length by the width

Area = 13*9= 117

Finally add the two areas together to get the area of the composite figure

117 + 16 = 133

Answer:

The trestle meets ground level at 0.875 units and 9.125 units

Step-by-step explanation:

Poorly formatted question.

The given equation is:

[tex]y = -x^2 + 10x - 8[/tex]

Required

The point where the trestle gets to the ground level

To do this, we set [tex]y = 0[/tex]

So, we have:

[tex]-x^2 + 10x - 8 = 0[/tex]

Multiply through by -1

[tex]x^2 -10x + 8 = 0[/tex]

Solve using quadratic formula:

[tex]x= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where:

[tex]a = 1; b =-10; c = 8[/tex]

So, we have:

[tex]x= \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*8}}{2*1}[/tex]

[tex]x= \frac{-(-10) \± \sqrt{68}}{2*1}[/tex]

[tex]x= \frac{-(-10) \± 8.25}{2}[/tex]

[tex]x= \frac{10 \± 8.25}{2}[/tex]

Solve the fraction

[tex]x= 5 \± 4.125[/tex]

Split

[tex]x= 5 + 4.125\ or\ x= 5 - 4.125[/tex]

[tex]x= 9.125\ or\ x= 0.875[/tex]

Answer:

C. 11/2÷9/4

hours, the tank loses 5 + \frac{1}[2} = \frac{5*2 + 1}{2} = \frac{11}{2} gallons. How much does it lose in an hour?

So

\frac{9x}{4} = \frac{11}{2}

Answer: 15$

Step-by-step explanation:

Given

Kendra spent one-third of allowance on a book and two-fifth on snack.

If she had four dollar remaining after purchase

Suppose x is the original amount

[tex]\therefore x-\dfrac{x}{3}-\dfrac{2x}{5}=4\\\\\Rightarrow \dfrac{15x-5x-6x}{15}=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15[/tex]

Thus, 15$ was her total allowance.

The solutions to the quadratic equation [tex]\rm x^2 + 2x = 25[/tex] is [tex]-1\pm \sqrt{26 }[/tex].

Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations.

The given equation is;

[tex]\rm x^2 + 2x = 25\\\\x^2+2x-25=0[/tex]

The solutions to the quadratic equation is determined by the following formula;

[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Where the value of a = 1, b = 2, and c = -25.

Substitute all the values in the formula;

[tex]\rm x =\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\\rm x =\dfrac{-2\pm \sqrt{2^2-4\times 1\times (-25)} }{2\times 1}\\\\ x =\dfrac{-2\pm \sqrt{4+100} }{2}\\\\x =\dfrac{-2\pm \sqrt{104} }{2}\\\\x =\dfrac{-2\pm \sqrt{26 \times 2\times 2} }{2}\\\\x =\dfrac{-2\pm 2\sqrt{26 }}{2}\\\\x = 2 \times \dfrac{-1\pm \sqrt{26 }}{2}\\\\x=-1\pm \sqrt{26 }[/tex]

Hence, the solutions to the quadratic equation [tex]\rm x^2 + 2x = 25[/tex] is [tex]-1\pm \sqrt{26 }[/tex].

The sum of the interior angles in a triangle is 180 degrees. Therefore, if we add all of these angles up, they will be equal to 180.

Answer:

3 pens.

Step-by-step explanation:

x+y=7 where x is # of pens and y =# of pencils

3x + 2y= $18

from first equation, x=-y+7 so substitute that into other equation

3(-y+7)+2y=18

-3y+21+2y=18

-y=18-21

-y=-3

y=3

now replace y =3 into first equation

x+3=7

x=4

Answer:

it's easy the value of y will be 70.

Both are corresponding angles and their sum will be 180

[tex]\\ \sf\longmapsto y+70=180[/tex]

[tex]\\ \sf\longmapsto y=180-70[/tex]

Answer:

21

Step-by-step explanation:

We can set Andrea's current age as x.

In 11 years, her age will be half the square of her age 13 years ago. We get the equation:

[tex]x+11=\frac{(x-13)^2}{2} \\2(x+11)=(x-13)^2\\2x+22=x^2-26x+169\\x^2-28x+147=0\\(x-21)(x-7)=0\\x=21, x=7[/tex]

Ok, now we know that Andreas age could be either 21 or 7. However, the problem states that "in 11 more years my age will be hald the square of my age 13 years ago." It would not make sense for Andrea to be currently 7 if she was not yet born 13 years ago.

Therefore, Andrea's age is 21.

Answer:

27 is the answer

Step-by-step explanation:

We have this proportion....

36 / 12 = x / 9 where x is the model door height

Cross-multiply

36*9 = 12 * x

324 = 12 *x divide both sides by 12

27 = x and that's the model height in centimeters

11/6 = 1. 8333

23/9= 2. 555
