Can someone please help will mark brainliest.

When the balloon is on the ground, it is at point 0. It starts to go up at 5 f/m for a time of 4 minutes. So we will multiply 5 by 4 to get 20. At this point, the balloon is 20 feet off the ground. However, we now know that the balloon descends at 2 f/m at a time of 7 minutes. So we must multiply 2 by 7 to get 14. So we know it was at 20, and then it went down by 14.

20 - 14 = 6 feet

This means that the balloon is now 6 feet above the ground.

I hope I've helped! :)

x ≥ $15

Step-by-step explanation:

At least means ≥

4x ≥ $60     Replace the inequality sign with an = sign and solve the equation.

4x = $60

x  = $60 ÷ 4

x = $15                 Now put the inequality sign back into the problem

 x ≥ $15

Answer:

D. 23/25

Step-by-step explanation:

Add all the numbers inside the venn diagram for the number of outcomes

> 10+2+8+8+6+5+7 = 46

Then add all the numbers inside and outside the venn diagram for the number of possibilities

> 10+2+8+8+6+5+7+4 = 50

[tex]p(a \: u \: b \: u \: c \: ) = \frac{total \: number \: of \: outcomes}{total \: number \: of \: possibilities} [/tex]

[tex]p( a \: u \: b \: u \: c) = \frac{46}{50} [/tex]

[tex]p(a \: u \: b \: u \: c \: ) = \frac{23}{25} [/tex]

Answer:

Step-by-step explanation:

3/9 is the same as 1/3.

It can't be D since 5/12 isn't 1/3.

It can't be A since 2/3 and 3/3 don't equal 1/3.

It can't be C since everything listed is equal to 2/3.

mutiply 92 by 0.10 and you'll get 9.2

So each text costs 10 cents.

181 snacks

27 students

How many snacks she need to make in order for each student to receive 7 snacks.

[tex]7 \times 27[/tex]

[tex] = 189[/tex]

[tex]189 - 181[/tex]

Answer:

x = 25; 47 degrees, 47 degrees, 86 degrees

Step-by-step explanation:

the two triangles are congruent so they have the same angles

that means 2x - 3 = x + 22

2x - 3 = x + 22

subtract x from each side

x - 3 = 22

add 3 to both sides

x = 25

and this is your answer

assuming that the triangles are isosceles triangles two of the angles are the same

the angles with the x on it are 47 after calculating

that means that the other angle across from it is also 47

a triangles angles added up is 180

47 + 47 + n = 180

the last angle after calculating is 86 degrees

Answer:

246

Step-by-step explanation:

Given that,

→ 246 {final answer}

Hence, the answer is 246.

Queremos encontrar dos números enteros tales que su diferencia sea de 6 y la suma de sus cuadrados sea igual a 260.

Veremos que los dos números son 8 y 14.

Primero, podemos definir esos números como A y B.

Entonces tenemos que:

A - B = 6

A^2 + B^2 = 260

Esto es un sistema de ecuaciones.

Para resolverlo, el primer paso es aislar una de las variables en una de las ecuaciones, vamos a hacer esto en la primera.

A - B = 6

A = 6 + B

Ahora reemplazamos esto en la otra ecuación.

A^2 + B^2 = 260

(6 + B)^2 + B^2 = 260

36 + 12*B + B^2 + B^2 = 260

36 + 12*B + 2*B^2 = 260

Ahora podemos resolver esto para B:

2*B^2 + 12*B + 36 - 260 = 0

2*B^2 + 12*B - 224

Las soluciones estan dadas por la formula de Bhaskara:

[tex]B = \frac{-12\pm \sqrt{12^2 - 4*2*(-224)} }{2*2} \\\\B = \frac{-12 \pm 44 }{4}\\\\B = (-3 \pm 11)[/tex]

Entonces las dos soluciones son:

B = -3 + 11 = 8

B = -3 - 11 = -14

Sabemos que los números son positivos, asi que elejimos la primera, entonces tenemos:

B = 8.

Con esto podemos calcular el valor de A como:

A - B = 6

A = 6 + B = 6 + 8 = 14

Entonces los dos números son:

8 y 14.

Answer:

Step-by-step explanation:

12/100 × 20000

= 2400

Price customer must pay = 20,000+ 2400 = 22400.

If price of a machine is given as GHC 20,000 plus VAT. If the VAT rate is 12%. Then 22400 is the price that a customer must pay for the machine.

Percentage, a relative value indicating hundredth parts of any quantity.

Given,

The price of a machine is given as GHC 20,000 plus VAT

The VAT rate is 12%,

We need to find how much a customer has to pay for the machine..

12% is changed to decimal number by dividing with 100.

12/100=0.12

Now multiply 20000 with 0.12 to find 12% of 20000

0.12×20000=2400

Now we have to add 2400 with 20000 to get the cost of machine after adding VTA

20000+2400=22400

Hence 22400 is the price that a customer must pay for the machine.

Answer:

Step-by-step explanation:

To find the original width, multiply 15.8 by w, and by 5.2.

You'll get 327.65 = 15.8w + 82.16.

Next, do the opposite of the symbol from both sides, 327.65 - 82.16 = 15.8w + 82.16.

The constant is 82.16, and the symbol is +, the opposite of plus is -, and thus subtract the constant from both sides.

You'll get 245.49 = 15.8w.

Now do the opposite of the symbol (a number next to a variable is multiplication, so do division, and divide 15.8 on both sides.

245.49/15.8 = 15.8w/15.8, which equals 15.5373417722.

Answer:

110 pounds

Step-by-step explanation:

Let the weight of Sandra, Peter and Martin be S, P and M pounds respectively.

S +P= 275 -----(1)

S +M= 245 -----(2)

S +P +M= 410 -----(3)

(3) -(1):

S +P +M -(S +P)= 410 -275

S +P +M -S -P= 135

M= 135

Substitute M= 135 into (2):

S +135= 245

S= 245 -135

S= 110

Thus, Sarah weighs 110 pounds.
