How many points does a student need to score 70% on a 80 point test?

Answers

Answer 1

Answer: 56

Step-by-step explanation:

70÷100×80=56

Answer 2

Answer:

56

Step-by-step explanation:

Another way to write this question is "What percent of 80 is 70%."

So we would write a percent proportion:

x/80=70/100

To find x, we will do (80*70)/100 which is 5600/100 which is 56.

You could also use benchmark fractions:

10% of 80 is 8

10% * 7 = 70% so 8 * 7 also equals 70%

8 * 7 = 56

Hope this helped, let me know if you have any questions.

Se lanzan 7 volados consecutivos y en todos ellos ha caído águila. ¿Cuál es la probabilidad de que en el décimo volado también caiga águila? En todos los eventos la probabilidad ha sido ½; por lo cual, en el décimo volado sigue la misma probabilidad 1/2

Answers

Respuesta: 0.5

Explicación paso a paso:

El posible resultado es 2:

1.) que cae un águila

2.) que un águila no cae

Cada resultado posible con igual probabilidad:

Probabilidad = resultado requerido / resultados posibles totales

P (cae un águila) = 1/2

P (el águila no cae) = 1 - 1/2 = 1/2

Por lo tanto, la probabilidad de que un águila caiga en la décima mosca es la misma que las probabilidades previas de que un águila caiga o no y es independiente. El hecho de que el águila haya caído en siete moscas consecutivas no aumenta la probabilidad de que el águila haya caído en la décima mosca.

have a nice day!!!

Answer:

Step-by-step explanation:

Slope intercept form of a line is y=mx+b so we need to solve for y.

y-1=45(x+5) first expand right side

y-1=45x+225 now add 1 to both sides.

y=45x+226

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).

460, 451,442

Find the 37th term.

Answers

Answer:

136

Step-by-step explanation:

This is an arithmetic sequence

The formula is an = a1 + f × (n-1)

n= the number we are trying to find = 37

a= the number in any given space on the sequence

a1= 460

f= the common difference between the numbers

f= -9 because you subtract 9 from each to get the number

a37= 460-9(37-1)

a37= 460-9(36)

a37= 460- 324

a37= 136

Given :

[tex] \\ [/tex]

The first three terms of a sequence are 460, 451, 442

[tex] \\ [/tex]

To Find :

[tex] \\ [/tex]

37th term of sequence = ?

[tex] \\ [/tex]

Solution :

[tex] \\ [/tex]

Clearly these three terms are making an arithmetic sequence, with :

First term, a = 460 Common difference, d = 451 - 460 = - 9

[tex] \\ [/tex]

Now, we have to find 37th term of sequence = [tex] \tt a_{37}[/tex]

[tex] \\ [/tex]

Now, we know that :

[tex] \large \underline{\boxed{\bf{a_{n} = a + (n-1)d}}}[/tex]

[tex] \\ [/tex]

[tex] \tt : \implies a_{37} = a + (37-1)d[/tex]

[tex] \tt : \implies a_{37} = a + 36d[/tex]

[tex] \\ [/tex]

Now, by substituting values of a and d :

[tex] \tt : \implies a_{37} = 460 + 36 \times (-9)[/tex]

[tex] \tt : \implies a_{37} = 460 - 324[/tex]

[tex] \tt : \implies a_{37} = 136[/tex]

[tex] \\ [/tex]

Hence, value of 37th term of given sequence is 136.

Amanda has $56.10 in her bank account in March. In May she has 4 times as much money in her account than she did in March. In June she adds $75.22 to her account. How much money does Amanda have in her account in June?

Answers

Answer:

Step-by-step explanation:

Given

7x(x - 11) - 2(x - 11) = 0 ← factor out (x - 11) from each term

(x - 11)(7x - 2) = 0

Equate each factor to zero and solve for x

x - 11 = 0 ⇒ x = 11

7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]

g(x) is the function from the table which gives values that could come from the exponential function.

What is a function?

A relation is a function if it has only One y-value for each x-value.

We have to find the function from the table which gives values that could come from the exponential function.

The exponential function is a mathematical function denoted by .

As we observe the g(x) function.

When x =1, g(x)=2

x=2, g(x)=4

x=3, g(x)=8

g(x)=2ˣ is the required function which is in exponential form

Hence, g(x) is the function from the table which gives values that could come from the exponential function.

Amount discounted: si

?

Answers

9514 1404 393

Answer:

  $14

Step-by-step explanation:

Computing 40% can be done a couple of ways.

  40% = 40/100 = 4/10 = 2/5

  40% of 35 = (2/5)(35) = 2(35/5) = 2(7) = 14

__

  40% = 4/10 = 2(2(1/10))

  40% of 36 = 2(2(1/10)(35)) = 2(2(3.5)) = 2(7) = 14

The amount discounted is $14.

Mrs. Roberts is 3 times as old as her son. The sum of their ages is 48 years.
How old was Mrs. Roberts when her son was born?

Answers

Answer:

24

Step-by-step explanation:

To find how old Mrs. Roberts was when her son was born, we first need to know both of their ages. I'm going to give Mrs. Roberts the variable m and her son the variable s.

Let's turn the two sentences about their ages into equations:

m=Mrs. Roberts and 3s= three times as old as her son

m=3s

m+s is the sum of their ages

m+s=48

Now substitute the first equation into the second one:

m+s=48

(3s)+s=48

4s=48

s=12

The son is 12 years old. Now substitute s into one of the equations to solve for the mother's age:

m=3s

m=3(12)

m=36

Mrs. Roberts is 36. Since they are asking how old she was when her son was born, we will subtract her son's age from her age, since she would be 12 years younger:

36−12=24

Mrs. Roberts was 24 when her son was born.
