Find the missing value of x and y.

9514 1404 393

Answer:

  -31/15

Step-by-step explanation:

Put the numbers in the expression and do the arithmetic.

  [tex]c-4x=-\dfrac{7}{15}-4\cdot\dfrac{2}{5}=-\left(\dfrac{7}{15}+\dfrac{8}{5}\right)\\\\=-\left(\dfrac{7}{15}+\dfrac{24}{15}\right)=\boxed{-\dfrac{31}{15}}[/tex]

Answer:

yes I knowww

find root

a) 7

b) -9

Answer:

1,000,000,000 [tex]m^3[/tex]

Step-by-step explanation:

1 kilometer is equal to 1000 meters, and 1 [tex]km^3[/tex] is 1 km * 1 km * 1 km

Therefore,

1000m * 1000m * 1000m = 1,000,000,000 [tex]m^3[/tex]

Hope this answer helped! :)

Answer:

Center= (-9,6) Radius=5

Step-by-step explanation:

correct answer:

( x + 9 ) ² + ( y - 6 ) ² = 25

center = ( -9, 6 )

radius = 5

equations:

we know from the given equation that the center would be (-9, 6) because we have to plug into the equation; ( x – h ) ² + ( y – k ) ² = radius²

how to find the center coordinates:

if youre confused on how we got the -9, by using the negative addition rules:

x - (-9) we can simplify that to ( x + 9 ) like shown above so that how we got -9. It's a little easier to find the 6 because its just x - 6 so we dont have to simplify anything its just 6.

how to find the radius:

the radius is a little more difficult to find, but, since we are given 25, we can just type the square root of 25 (√25) which would be 5!

thats it!! hope this helps<3

Answer:

688.7

Step-by-step explanation:

Top and Bottom

Area = 3/4 * pi * r^2

r = 6

Area = 3/4 * 3.14 * 6^2

Area =                                                               84.78

Don't round yet.

Vertical surface

Vertical surface = 3/4 * pi * d * h

d = 12 inches (the diameter)

Vertical surface = 3/4 * 3.14 * 12 * 15

Vertical surface =                                          423.9

Two inner faces

They are both rectangles

Area = 2 * L * W

L = 15

w=6

Area = 2 * 15 * 6                                            180

Total                                                               688.68

Total = 688.7

Answer:

$40

Step-by-step explanation:

It's very simple, 0.1 * 150 = 15. Then add $25 by 15. 25 + 15 = 40.

Answer:

X can be anything below 4

Answer:

x should be 1,2, or 3

Step-by-step explanation:

because if you take 3x4 it would be 12 (the same) so that's wrong. so it would have to be lower than that

Answer:

La medida del ángulo de la abertura menor es 29°.      

Step-by-step explanation:

Podemos calcular la medida del angulo de la abertura menor hallando el valor de "x" en la siguiente ecuación:

[tex] (x + 5) + (2x + 13) = 90 [/tex]   (1)

Dado que en la figura podemos observar que la suma de ambos ángulos de abertura resulta en un ángulo rectángulo.

Al resolver la ecuación (1) tenemos:                                  

[tex] x + 2x = 90 - 13 - 5 [/tex]

[tex] 3x = 72 [/tex]

[tex] x = 24 [/tex]

Ahora, podemos encontrar los ángulos de abertura.

Angulo de abertura menor:

[tex] x + 5 = 24 + 5 = 29^{\circ} [/tex]

Angulo de abertura mayor:

[tex] 2x + 13 = 2*24 + 13 = 61^{\circ} [/tex]

Por lo tanto, la medida del ángulo de la abertura menor es 29°.

central angle measure

Answer:

25.12 in³

Step-by-step explanation:

v = (1/3)πr²h

Plug in the givens

v = (1/3)(3.14)(4/2)²(6)

v = (1/3)(3.14)(4)(6)

v = 25.12

Answer:

the volume is 25.12. that's the correct answer

Answer:

E = J, and X = 11

Step-by-step explanation:

Okay. So we know that the total degree in a triangle is 180 degrees. We see that the two triangle are similar (E = J) so J = 80, S = 36, and P = 4x +20

We can make this into the equation 80 + 36 +4x +20 = 180

We then simplify 136 + 4x = 180

Isolate 4x 4x = 180 - 136

4x = 44

If Regina wants a mean of 90, she needs to sell 94 books on the 5th day.

Answer:

$45

Step-by-step explanation:

De 11.00am a 3.00pm hay 4 horas de diferencia.

Eso seria 12x4=$48

Pero necesitamos restarle 1/4 de hora, por lo que se estaciono a las 11.15am y no a las 11.00am

1/4 de hora o 15min= $3.00

48-3=45

Answer:35 51 98

Step-by-step explanation:

Answer:

Hello! Thanks for posting the question again!

Anyways here are the answers...

d = 35 because its a vertical angle

e = 51 because its a vertical angle

Now to find f we have to add these up then subtract by 360 then ÷ by 2 so 51 + 51 + 35 + 35 = 172 360 - 172 = 188 188 ÷ 2 = 94 so f = 94

Answer:

I will solve your system by substitution.

y=2;2x+y=8

Step: Solvey=2for y:

Step: Substitute2foryin2x+y=8:

2x+y=8

2x+2=8

2x+2+−2=8+−2(Add -2 to both sides)

2x=6

2x

=

(Divide both sides by 2)

Answer:

The missing angle is 50

Step-by-step explanation:

40 + 90 + x = 180

x = 180 - 90 - 40

x = 50

The missing angle is 50.

Answer:

the answer is 1/8

Step-by-step explanation:

Answer:

a = [tex]4\sqrt{3}[/tex]

b= 4

Step-by-step explanation:

It's a 30-60-90 triangle based on the given picture. A right triangle too

Use sine, cosine, and tangent to solve for the side.

To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.

OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and [tex]x\sqrt{3}[/tex] for long leg

So either way, b = 4

To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.

OR you can use the same rule, 30-60-90 triangle to save time

a will end up = [tex]4\sqrt{3}[/tex]
