pls help solve question 3

Answer:

20

Step-by-step explanation:

what is 42-22?

it is 20. Next time, use a calculator or get your additon and normal calulations really good.

Step-by-step explanation:

Find the prime factorization of 35

35 = 5 × 7

Find the prime factorization of 56

56 = 2 × 2 × 2 × 7

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 7

1.6

0.4

2 .  0

Answer:

y = 1.6

Step-by-step explanation:

u are finding what y equals so u set up ur equation like this

y + 0.4 =       2

   -  0.4 = - 0.4

----------------------

subtract 0.4 on both sides u get 1.6

and now ur left with y so y = 1.6 ! pretty ez right

Answer:

[tex]Total = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]Carol = \frac{1}{8}[/tex]

[tex]Luke = \frac{3}{8}[/tex]

Required

How far did they row together

To do this, we simply add the distance they both covered.

[tex]Total = Carol + Luke[/tex]

This gives;

[tex]Total = \frac{1}{8} + \frac{3}{8}[/tex]

Take LCM

[tex]Total = \frac{1+3}{8}[/tex]

[tex]Total = \frac{4}{8}[/tex]

Simplify

[tex]Total = \frac{1}{2}[/tex]

Hence, they both rowed 1/2 mile

Answer:

[tex]Area = \frac{25x^2}{2}[/tex]

Step-by-step explanation:

Given

Shape: Parallelogram

[tex]PR = 5x[/tex]

[tex]QS = 5x[/tex]

[tex]\theta = 90[/tex]

Required

Find the area of the parallelogram

Because we were given the measure of the diagonals, the area is:

[tex]Area = \frac{1}{2} * PR * QS * \sin \theta[/tex]

This gives:

[tex]Area = \frac{1}{2} * 5x * 5x * \sin \ 90[/tex]

[tex]Area = \frac{1}{2} * 5x * 5x * 1[/tex]

[tex]Area = \frac{1}{2} * 25x^2[/tex]

[tex]Area = \frac{25x^2}{2}[/tex]

Answer:

1/10 x 5/6 = 5/60 or 1/12

Step-by-step explanation:

multiply the denominator and numerators. If it is needed to be simplified,

find the gcf of 5 and 60. That would be 5. So divided 5/60 by 5. This would be your final answer of 1/12.

Have a nice day, and I hope this helps you!

Answer:

y=8x/3

Step-by-step explanation:

In this question the options are not given clearly but the value of x in terms of y can be written as

[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]

According to the given situation in the question

Andrew calculates that 40% of 50% of x = 20% of 30%  of y

Given that x ≠ 0

The given condition can be formulated in the form of equation (1)  as follows

[tex]\rm 40\% \times 50\% \times x = 20\% \times 30\%\times y ........(1)\\[/tex]

Equation (1) can be further solved to get

[tex]\rm \dfrac{40}{100} \times \dfrac{50}{100} \times x = \dfrac{20}{100}\times \dfrac{30}{100}\times y[/tex]

[tex]\rm 2/5\times (1/2)\times x = (3/50)\times y[/tex]

[tex]\rm x /5 = 3/50 \times y \\x = \dfrac{3y}{10}[/tex]

In this question the options are not given clearly but the value of x in terms of y can be written as

[tex]\rm \bold{x = \dfrac{3}{10} \times y }[/tex]

Answer:

62.48 ft.

Step-by-step explanation:

Initial height: 50 ft.

First rebound: 10 ft.

Second rebound: 2 ft.

Third rebound: 0.4 ft.

Fourth rebound: 0.08 ft.

If we approximate the fourth rebound to zero, we'll have:

50 + 10 + 2 + 0.4 + 0.08 = 62.48 ft.
