Answers

Answer 1

Answer:

x = 7

Step-by-step explanation:

x * (log(2)) = log(128)

x = log(128) / log(2)

x = 7

[tex] \frac{16}{25} [/tex]

have a nice day

Answer:

[tex]\frac{16}{25}[/tex]

Step-by-step explanation:

We have four fractions and are asked to find the next one in the sequence.

So we see that 8/25 and 10/25 are together, which then follows up with 12/25 and 14/25.

Do we see a pattern? Yes indeed, the numerator is going up two values of every sequence, therefore we need to add 2/25 to 14/25 to find the next fraction.

[tex]\frac{14}{25} + \frac{2}{25}[/tex]

[tex]\frac{16}{25}[/tex]

Problem Example: Aladdin has 1/6 apples. A genie multiplied it by 4. How many apples would Aladdin have?

Solution: 4/6 apples.

Step-by-step explanation:

Explanation:

Aladdin has 4/6 apples because 1/6 multiplied by 4 is the same thing as adding 1/6 by 1/6 by 1/6 by 1/6.

Answers

Answer:

3,040$

In a race, 41 out of the 50 bicyclists finished in less than 38 minutes. What percent of bicyclists finished the race in less than 38 minutes? Write an equivalent fraction to find the percent.

Answers

for left put 2 on each
On the box over 100 put 82, and put 82 in the box on the right

to find the percent, you will double everything because you only have 50 as the base and doubled its 100. 41 times 2 it’s equal to 82 so 82% of the bicyclists finished in less than 38 minutes. As a fraction it would be 41 over 50.

Ginger spins the spinner below and rolls the number cube. What is the probability that Ginger's spinner will land on 3 and she will roll a 4?

Because there is 7 numbers on the spinner and 6 on the cube so 7 times 6 is 42

Count how many sides there are on the spinner and then make a fraction to answer it. Also a cube doesn’t have just 3 sides.
