Ben has a collection of baseball cards. He has a total of 1,600 cards. Of the baseball cards, 35% are dated before 1980, 25% are dated from 1980 to 2000, and
the rest are dated after 2000.
How many baseball cards in Ben's collection are dated after 2000?

Answers

Answer:

640 cards

Step-by-step explanation:

If the rest are dated after 2000, that means that 40% are dated after 2000, since 25% + 35% = 60%

To find how many are dated after 2000, multiply 1,600 by 0.4:

1,600(0.6) = 640

So, 640 of the baseball cards are dated after 2000

Absolute value equations are equations where the variable is within an absolute value operator, like |x-5|=9. The challenge is that the absolute value of a number depends on the number's sign: if it's positive, it's equal to the number: |9|=9. If the number is negative, then the absolute value is its opposite: |-9|=9.

You and a group of friends take turns planting 2 trees each at a campsite. After the first person plants 2 trees, there are 12 trees at the campsite. A. Write an equation for the nth term of the arithmetic sequence. Let n represent the position in the sequence and let an represent the number of trees. C. After 8 more people plant trees, how many trees are at the campsite?

Answers

Answer:

The equation for the nth term will be;

An = 10 + 2n

After the 9th planter ( 8 more than the initial one); number of trees will be 28

Step-by-step explanation:

After the first person plant two trees, there were 12 trees at the plant sites

What this mean is that initially, they were 12-2 = 10 trees at the plant site

The nth term of the sequence which represents the number of trees given the number of persons that have planted will be;

An = 10 + 2n

Now, after 8 more people planted, since we had one that already planted, the total number of planters is now 9 planters

So using the equation, n will be 9

So ; A9 = 10 + 2(9)

A9 = 10 + 18

A9 = 28

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression 2a+b when the value of a is 5 and b is 4  is equal to 14.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the expression 2a+b, whose values are needed to be calculated when the value of a is 5 and the value of b is 4. Therefore, the value of the given expression 2a+b can be written as,

2a + b

Substitute the value of a and b,

= 2(5) + 4

= 10 + 4

= 14

Hence, the value of the expression 2a+b when the value of a is 5 and b is 4 is equal to 14.

Which function has the same graph as x + y = 11?

A.
f(x) = -y + 11
B.
f(x) = -x + 11
C.
f(x) = x − 11
D.
f(x) = y − 11

Answers

Answer:

B. f(x) = -x + 11

Step-by-step explanation:

y = f(x)

therefore

x + y = 11 → x + f(x) = 11     |subtract x from both sides

x - x + f(x) = 11 - x

f(x) = -x + 11

The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.

Therefore, the correct answer is:

B. f(x) = -x + 11

Here,

To find the function with the same graph as x + y = 11,

we need to isolate y in the equation to make it of the form y = f(x).

Given equation: x + y = 11

Subtract x from both sides of the equation:

y = 11 - x

Now, we have the equation in the form y = f(x).

so, we get, f(x) = -x + 11

i.e. The function which has the same graph as x + y = 11 is: f(x) = -x + 11

so, we have,

The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.

Therefore, the correct answer is:

B. f(x) = -x + 11

O Perímetro de triângulo isósceles mede 24cm. Qual é a medida de comprimento dos lados congruentes sabendo-se que o lado não congruente mede 7cm de comprimento?

Answers

Answer:

La longitud de los lados congruentes =

B = 8.5cm

C = 8.5 cm

Step-by-step explanation:

El perímetro del triángulo isósceles mide 24 cm.

El lado no congruente mide 7 cm de largo.

Lados congruentes significa lados que son iguales o iguales entre sí.

El perímetro de un triángulo es =

Lado A + Lado B + Lado C

Por lo tanto,

24 = 7 cm + B + C

24 - 7 = B + C

17 cm = B + C

Los dos lados son congruentes,

B = C

Por lo tanto, 17 cm / 2

= 8.5 cm

La longitud de los lados congruentes =

B = 8.5 cm

C = 8.5 cm
