Fred bought 4 new baseball cards to add to his collection. The next day his dog ate half of his collection. There are now only 33 cards left. How many cards did Fred start with ?

Answer:

its a =y+z/w-x

Step-by-step explanation:

First, subtract  

z  and  a w  from each side of the equation to isolate the  

a  terms while keeping the equation balanced

than factor a A from each term on the left side of the equation

now divide each side of the equation by x-w to solve for a while keeping the equations balanced

you then multiply the right side of the equation by a form of 1 to rewrite the expression as

a=-1/-1 x -y & -z/ \-x/-w

than you remove the ones add a addition to y and the z  and then you flip the x and  the why and add multiplication

Answer:

40%

Step-by-step explanation:

2/5= 4/10

4/10= 40%

The percent that is equivalent to two-fifths is 40%. The correct option is 40%.

To determine the percent equivalent to two-fifths, we need to convert the fraction into a percentage.

The fraction two-fifths can be written as 2/5. To convert this fraction to a percentage, we divide the numerator (2) by the denominator (5) and multiply the result by 100.

2/5 x 100

= 0.4 x 100

= 40%

Therefore, the percentage equivalent to two-fifths is 40%.

Among the provided options:

0.4% is incorrect. It represents four-tenths of a percent, not 40%.

2.5% is incorrect. It represents two and a half percent, not 40%.

25% is incorrect. It represents one-fourth or 25%, not 40%.

40% is the correct answer, as explained above.

Hence, the option that represents the percent equivalent to two-fifths is 40%.

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

B (from down below) They are similar but your q does not match up with the picture

Step-by-step explanation:

to determine if two triangles are similar you have to make sure the ratios are the same. So 10 / 8 = 1.25, so all sides should have this ratio. 15 / 12 is also 1.25 so you know to sides are similar and also the triangles ARE SIMILAR. So The statement would be KMN is similar to KLP.

Step-by-step explanation:

The probability of rolling a 6 on a 6-sided die is 1/6, and the probability of rolling a 4 on a 6-sided die is also 1/6.

Assuming that the rolls are independent (i.e., the outcome of one roll does not affect the outcome of the other roll), the probability of rolling a 6 and then a 4 is the product of the probabilities of each individual event:

Probability of rolling a 6 and then a 4 = (Probability of rolling a 6) x (Probability of rolling a 4)

= (1/6) x (1/6)

= 1/36

Therefore, the probability of rolling a 6 and then a 4 on a 6-sided die rolled twice is 1/36, or approximately 0.0278 (2.78%).

Answer:

Slope is 3.

Step-by-step explanation:

Slope is change in y to change in x:

\(\displaystyle{\text{slope} = \dfrac{\Delta y}{\Delta x}}\\\\\displaystyle{\text{slope} = \dfrac{y_2-y_1}{x_2-x_1}}\)

In mathematics, slope is generally declared as "m" variable.

Also, we are given two coordinate points. Let \(x_1\) be -1, \(x_2\) be 1, \(y_1\) be -1 and \(y_2\) be 5.

Therefore:

\(\displaystyle{m = \dfrac{5-\left(-1\right)}{1-\left(-1\right)}}\\\\\displaystyle{m=\dfrac{5+1}{1+1}}\\\\\displaystyle{m=\dfrac{6}{2}}\\\\\displaystyle{m=3}\)

Therefore, the slope is 3.

Answer:

153 units squared

Step-by-step explanation:

first, multiply 10 x9 to find the area of the rectangle, which is 90

then find the area of the triangle. The formula for area of a triangle is

A=1/2bh

so, 7 x 9= 63 divided by 2 is 31.5

since there are 2, multiply 31.5 x 2= 63

add 63 to 90 which is 153

Answer: 153 sq. units

Step-by-step explanation:

Base a = 10

Base b  = 7x2 = 24

Height = 9

area of trapezoid = 1/2 * (a+b) * h

= 10+24 * 9 /2

= 306/2 = 153

Answer: 1526.04 cubic yards

Step-by-step explanation: 3.14 x (9)^2 x 6

Answer: 1526.04 cubic yards

Step-by-step explanation: 3.14 x (9)^2 x 6

=81 x 6 x 3.14

= 1526.04 cubic yards

Answer:

2x - 3y = 18  (1)

5x + 9y = -10​   (2)

<=>

Multiply both sides of (1) by 5, and multiply both sides of (2) by 2, then:

10x - 15y = 90

10x + 18y = -20

Subtract (2) to (1):

=> 33y = -110 => y = -110/33

Substitute y back into (1):

=> 2*x - 3*(-110/33) = 18

=> 2*x + 10 = 18

=> 2*x = 8

=> x = 4

=> Solution: x = 4, y = -110/33

Step-by-step explanation:

You find range by subtracting the lowest amount from your data by the highest amount. The highest number in Ms. Gambino's class is 12, and the lowest is 5.

\(12-5=7\)  This is the range of Ms. Gambino's class

The highest number in Mr. Joe's class is 10 and the lowest is 5

\(10-5=5\\\) This is the range of Mr. Joe's class.

Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.
