Answer:

x=-7

y=4

Step-by-step explanation:

I am assuming you want the values of x and y. We know that x=-2y+1 and 3x+8y=11. We can substitute the value of x (-2y+1) into the equation 3x+8y=11.

Therefore 3(-2y+1)+8y=11

Using the distributive property:

-6y+3+8y=11

2y+3=11

y=4

To solve for x, we will plug in 4 in -2y+1. So, x= -2(4)+1=-7.

Check: 3(-7)+8(4)=-21+32=11.

64.5 is answer for -[4.1-3(2.2)]/(0.2)^2+2

An expression is a combination of numbers, variables and operators.

-[4.1-3(2.2)]/(0.2)²+2

Use the BODMAS rule to simplify.

Minus of four point one minus three times of two point two. divided by minus zero point two square plus two.

= -[4.1-6.6]/0.04+2

four point one minus six point six is minus two point five.

= -[-2.5]/0.04+2

Two point five divided by zero point zero four

=2.5/0.04+2

Answer:  1000001010 base 2

=======================================================

Explanation:

There are two methods to solving this problem.

One method is to involve having a list of the powers of 2

And so on.

In that list should be 2^9 = 512. So 512 is a power of 2. It is the largest such power that is just under 522. Subtracting it off gets us

522-512 = 10

So that explains why the 2^9 slot in the answer is a '1'. This is the first '1' mentioned in the answer shown above. Then we have a string of '0's until we reach 1010 at the end. That long string of 0s indicate that we don't have any of the following powers: 2^8, 2^7, 2^6, 2^5, 2^4

It's when we get to 2^3 is when we finally have a power of 2 to add on.

Then note how 10-2^3 = 10-8 = 2

So the last term we need to add on is 2^1 = 2. Note the gap from 2^3 to 2^1 because of the first 0 in 1010

So that's how we end up with 1000001010 as our final answer.

Answer:

18 units²

Step-by-step explanation:

there are two ways to calculate the required area.

way 1.

the length of the side AB=7+2=9; the length of CD is 6-2=4 (note, CD⊥AC), then the required area is:

A=9*4/2=18.

way 2.

the coordinates of the vector AB=(0;-9), of vector AC=(4;-3).

The required area can be calculated using the formula: A=0.5*[ABxAC].

[tex]|A|=|\frac{1}{2}*\left[\begin{array}{ccc}0&-9\\4&-3\\\end{array}\right]|=|(-36):2|=18.[/tex]

Suppose the probability of being picked first in your class is 0.05. The odds of being picked first expressed in form of a: b is 1 : 19.

A probability is a number that represents the possibility or chance that a specific event will occur.

[tex]{\mathbf{\text{The probability of an event} = \dfrac{\text{number of desired outcome}}{\text{total number of possible outcome}}}[/tex]

From the given information;

∴

The odds of being picked first can be computed as:

[tex]\mathbf{=\dfrac{0.05}{1-0.05}}[/tex]

[tex]\mathbf{=\dfrac{0.05}{0.95}}[/tex]

[tex]\mathbf{\dfrac{1}{19}}[/tex]

= 1 : 19

Therefore, the odds of being picked first in terms of a: b is 1 : 19

Answer:

9): 64.7

10): 39$

Step-by-step explanation:

Answer:

64.7% and $39

Step-by-step explanation:

Question 9:

This means that the baseball team won 22/34 of their games through their entire season. In order to find the percentages of game they won, you divide 22 by 34, which comes out to 0.64705..., which becomes 64.705%. Rounding this to the nearest tenth, this percentage becomes 64.7%. Therefore, the percentage of games their baseball team is 64.7%.

Question 10:

We can represent this problem as the proportion:

[tex]\frac{27}{69.2} =\frac{x}{100}[/tex]

with x being the original price of the slacks.

We cross multiply to solve this equation. 27 times 100 is 2700. Next, we divide 2700 by 69.2, which comes out to 39.017341. Rounding this to the nearest whole number, this value comes out to 39. Therefore, the original price of these slacks is $39.

Answer:

Step-by-step explanation:

So if mischievous grows 8 7/12 inches every week, you have to multiply 8 7/12  times 4 (for the 4 weeks).

8 7/12 x 4= 34 4/12

Then add that to the snakes current length.

34 4/12+ 17 2/9=///

1) Change the fractions to have common denominators

4/12 x 3= 12/36

2/9 x 4= 8/36

2) Add. 8+12= 20. Denominators stay the same. 20/36.

3) Add the whole numbers. 34+17=51.

4) Put it all together. 51 20/36.

5) Simplify the fractions. 20 and 36 can be divided by 4.

20/4=5  36/4=9, 5/9

So, 34 4/12+17 2/9= 51 5/9

Mischievous will be 51 5/9 inches after 4 weeks.

To convert into feet, divided 51 by 12.

Answer:

f ( x ) = [ x ] + 1

Step-by-step explanation:

Using the normal distribution principle ; the probability that a randomly chosen chocolate is in the celebration box is 0.553

Zscore = (X - μ) ÷ σ

For X = 5 :

Zscore = (5 - 5.8) ÷ 1.3 = - 0.615

For X = 7 :

Zscore = (7 - 5.8) ÷ 1.3 = 0.923

Using a normal distribution table :

P(Z < 0.923) = 0.822

P(Z < - 0.615) = 0.269

P(Z < 0.923) - P(Z < - 0.615) = 0.822 - 0.269 = 0.553

Therefore, the probability of inclusion is 0.553.
